RESUMEN

BACKGROUND: Intraoperative conversion to open surgery is an adverse event during minimally invasive distal pancreatectomy (MIDP), associated with poor postoperative outcomes. The aim of this study was to develop a model capable of predicting conversion in patients undergoing MIDP. METHODS: A total of 352 patients who underwent MIPD were included in this retrospective analysis and randomly assigned to training and validation cohorts. Potential risk factors related to open conversion were identified through a literature review, and data on these factors in our cohort was collected accordingly. In the training cohort, multivariate logistic regression analysis was performed to adjust the impact of confounding factors to identify independent risk factors for model building. The constructed model was evaluated using the receiver operating characteristics curve, decision curve analysis (DCA), and calibration curves. RESULTS: Following an extensive literature review, a total of ten preoperative risk factors were identified, including sex, BMI, albumin, smoker, size of lesion, tumor close to major vessels, type of pancreatic resection, surgical approach, MIDP experience, and suspicion of malignancy. Multivariate analysis revealed that sex, tumor close to major vessels, suspicion of malignancy, type of pancreatic resection (subtotal pancreatectomy or left pancreatectomy), and MIDP experience persisted as significant predictors for conversion to open surgery during MIDP. The constructed model offered superior discrimination ability compared to the existing model (area under the curve, training cohort: 0.921 vs. 0.757, P < 0.001; validation cohort: 0.834 vs. 0.716, P = 0.018). The DCA and the calibration curves revealed the clinical usefulness of the nomogram and a good consistency between the predicted and observed values. CONCLUSION: The evidence-based prediction model developed in this study outperformed the previous model in predicting conversions of MIDP. This model could contribute to decision-making processes surrounding the selection of surgical approaches and facilitate patient counseling on the conversion risk of MIDP.

RESUMEN

Background and Objective: Early discharge following robot-assisted kidney transplantation (RAKT) is a cost-effective strategy for reducing healthcare expenses while maintaining favorable short- and long-term prognoses. This study aims to identify predictors of postoperative delayed discharge in RAKT patients and develop a predictive model to enhance clinical outcomes. Materials and Methods: This retrospective study included 146 patients aged 18 years and older who underwent RAKT at a single tertiary medical center from August 2020 to January 2024. Data were collected on demographics, comorbidities, social and medical histories, preoperative labs, surgical information, intraoperative data, and postoperative outcomes. The primary outcome was delayed postoperative discharge (length of hospital stay > 7 days). Risk factors for delayed discharge were identified through univariate and multivariate regression analyses, leading to the development of a risk scoring system, the effectiveness of which was evaluated through receiver operating characteristic curve analysis. Results: 110 patients (74.8%) were discharged within 7 days post-transplant, while 36 (24.7%) remained hospitalized for 8 days or longer. Univariate and multivariate logistic regression analyses identified ABO incompatibility, BUN levels, anesthesia time, and vasodilator use as risk factors for delayed discharge. The RAKT score, incorporating these factors, demonstrated a predictive performance with a C-statistic of 0.789. Conclusions: This study identified risk factors for delayed discharge after RAKT and developed a promising risk scoring system for real-world clinical application, potentially improving postoperative outcome stratification in RAKT recipients.

RESUMEN

Cleft lip re-repair is a procedure frequently endorsed to enhance a compromised nasolabial appearance. However, the actual effect of such revision surgery on the nasolabial appearance has scarcely been studied. Therefore, the aim of this study was to critically review surgical outcomes of patients that underwent surgical re-do of their cleft lip, using well-validated objective and subjective methods and standardised outcome measures. 20 patients with at least 6 months follow-up after cleft lip re-repair were assessed. Standardised pre- and postoperative photographs were analysed. The objective assessment was carried out using the SymNose-software. Furthermore, a subjective evaluation of the nasolabial area was conducted by ten examiners who rated seven parameters using a Likert-scale ranging from 1to5. The objective evaluation showed substantial improvement regarding symmetry values. Significant postoperative decrease in labial asymmetry from 26.42% (±8.13) to 18.77% (±6.28) (p < 0.001) and upper lip asymmetry in relation to the facial midline (26.91% (±8.03) vs. 18.27% (±5.17) (p < 0.001)) was observed. Similar results were corroborated in the subjective analysis. Differences regarding the ratings were detected considering the examiners' professional background and level of expertise. Cleft re-repair was found to significantly improve upper lip symmetry and lead to a more harmonious nasolabial appearance.

RESUMEN

BACKGROUND: Supra-sphincteric and high trans-sphincteric fistula are very challenging procedures for both the patient and the surgeon. We aimed to evaluate the outcomes of anal sphincter repair in the management of supra-sphincteric and high trans-sphincteric fistula-in-ano in terms of postoperative wound infection, bleeding, incontinence to flatus or stool, and recurrence within 1 year. PATIENTS AND METHODS: This single-center prospective cohort trial conducted from June 2020 to December 2023 at the Ain Shams University Hospitals included 20 patients who presented with supra-sphincteric or high trans-sphincteric fistula. There were nine (45%) male and 11 (55%) female patients, with a mean age of 41.5 years postoperatively. RESULTS: The mean duration of the procedure was 90.3 min (SD ± 11.9). During the first 2 weeks, ten (50%) patients scored their postoperative pain as mild, eight (40%) as moderate, and two (10%) as severe. Wound infection occurred in two (10%) patients and postoperative bleeding in three (15%) patients in the form of spotting after defecation. There were no cases of incontinence to stool. However, there were three (15%) cases of incontinence to gases. There were two cases (10%) of recurrence at the 1­year follow-up. Postoperative patient satisfaction was assessed on a 5­point Likert scale after 2 weeks: One patient (5%) was very dissatisfied, three (15%) patients were dissatisfied, and two (10%) patients were unsure, while five (25%) patients were satisfied and nine (45%) were very satisfied. CONCLUSION: Immediate sphincter repair in supra-sphincteric and high trans-sphincteric fistula through a lay-open procedure was determined to be safe, easier than classic operations, and associated with a low incidence of recurrence at the 1­year follow-up and a high quality of life.

RESUMEN

OBJECTIVE: While the benefits of minimally invasive aortic valve surgery compared with standard sternotomy have been widely described, the impact of preservation of pleural integrity (PPI) in minimally invasive surgery is still widely discussed. This study aims to define the role of PPI on postoperative and long-term outcomes after minimally invasive aortic valve replacement (MIAVR). METHODS: All 2,430 consecutive patients undergoing MIAVR (ministernotomy or right anterior minithoracotomy) between 1997 and 2022 were included in the study. Patients were divided into 2 groups: patients with and without PPI. PPI was considered the maintenance of the pleura closed without the need for a chest tube insertion at the end of the surgical procedure. A propensity-matched analysis was used to compare the PPI and not-PPI groups. RESULTS: After propensity matching, 848 patients were included in each group (PPI and not-PPI). The mean age was 70.21 versus 71.42 years, and the mean Society of Thoracic Surgeons predicted risk of mortality was 0.31% versus 0.30% in not-PPI versus PPI, respectively. The mean follow-up time was 147.4 months. Postoperatively, not-PPI versus PPI patients had a longer intensive care unit stay (9.7 vs 17.3 h, P < 0.001) and hospital length of stay (5.2 vs 8.9 days, P < 0.001). The rate of respiratory complications including the incidence of pneumothorax or subcutaneous emphysema, pulmonary atelectasis, and pleural effusion events requiring thoracentesis/drainage was significantly higher in not-PPI versus PPI. The 30-day all-cause mortality was higher in not-PPI versus PPI (0.029 vs 0.010, P = 0.003). Perioperative, short-term, and long-term all-cause mortality was significantly higher in the not-PPI group. CONCLUSIONS: PPI after MIAVR is associated with reduced incidence of postoperative complications, reduced lengths of stay, and improved overall survival compared with not-PPI. Therefore, a MIAVR tailored patient-procedure approach to maintaining the pleura integrity positively impacts short-term and long-term outcomes.

RESUMEN

Introduction This study highlights the relation between compound muscle action potential (CMAP) latency variations and the predictive value of facial nerve (FN) proximal-to-distal (P/D) amplitude ratio measured at the end of vestibular schwannoma resection. Methods Forty-eight patients underwent FN stimulation at the brainstem (proximal) and internal acoustic meatus (distal) using a current intensity of 2 mA. The proximal latency and the P/D amplitude ratio were assessed. House-Brackmann grades I & II indicated good FN function, and grades III to VI were considered fair/poor function. A P/D amplitude ratio > 0.6 was used as a cutoff to indicate a good FN function, while a ratio of ≤ 0.6 indicated a fair/poor FN function. Results The P/D amplitude ratio was measured for all patients, and the calculated sensitivity (SE), specificity (SP), positive predictive value (PPV), and negative predictive value (NPV) were 85.2, 85.7, 88.5, and 81.8%, respectively. The CMAPs from the mentalis muscle were then classified based on their proximal latency into group I (< 6 ms), group II (6-8 ms), and group III (> 8 ms). The SE, SP, PPV, and NPV became 90.5, 90.9, 95, and 83.3%, respectively, in group II. In group I, SE and NPV increased, whereas SP and PPV decreased. While in group III, SP and PPV increased, whereas SE and NPV decreased. Conclusion At a latency between 6 and 8 ms, the P/D amplitude ratio was predictive of outcomes with high SE and SP. When latency was < 6 ms or > 8 ms, the same predictive ability was not observed. Knowing the strengths and limitations is important for understanding the predictive value of the P/D amplitude ratio.

RESUMEN

BACKGROUND: Despite improvements, survival rates for gastric cancer remain low, even in developed countries, confirming the role of primary and secondary prevention. OBJECTIVE: This study aims to demonstrate the role of additional suspension sutures on the esophagojejunal anastomosis (EJA) to strengthen the anastomosis, i.e., relieve the mechanical suture. METHODS: A retrospective cohort study was conducted from 2011 to 2022 at the Clinic for Surgery, University Clinical Center Tuzla, Bosnia and Herzegovina. The experimental group consisted of patients placed with a suspension suture at the esophagojejunal anastomosis (EJA) site after total gastrectomy. The control group was patients without a suspension suture. The clinical and laboratory parameters available from the medical history were analyzed, X-ray passage, surgical complications, non-surgical complications, the length of hospitalization, the postoperative course, time of onset of postoperative complications, postoperative radiological follow-up and endoscopic postoperative follow-up were then analyzed. RESULTS: A total of 212 patients were included in the study: 87 in the experimental group with suspension sutures on the EJA and 125 in the control group without suspension sutures on the EJA. The two cohorts did not differ in other clinicopathologic parameters except perineural invasion, which was more prevalent in the control group. Patients in both groups were anemic and elevated values of C reactive protein (CRP) and decreased levels of proteins, albumin and globulin, with no significant difference between the two groups. The most common general complication was pleural effusion (28%), followed by pneumonia (∼22%). The most common complication in the experimental group was an intraabdominal abscess, while in the control group, it was a surgical wound infection. CONCLUSION: Our study did not show a statistically significant difference between the two analyzed EJA techniques created with a circular stapler, when it comes to postoperative course and outcome in patients with gastric cancer.

RESUMEN

Introduction: Patients with chronic pancreatitis (CP) as well as with pancreatic head carcinoma (CA) undergo the surgical intervention named "pylorus-preserving pancreatoduodenectomy according to Traverso-Longmire (PPPD)", which allowed a comparative analysis of the postoperative courses. The hypothesis was that patients with CA would have worse general as well as immune status than patients with CP due to the severity of the tumor disease and that this would be reflected in the more disadvantageous early postoperative outcome after PPPD. Methods: With the aim of eliciting the influence of the different diagnoses, the surgical outcome of all consecutive patients who underwent surgery at the Dept. of General, Abdominal, Vascular and Transplant Surgery at the University Hospital at Magdeburg between 2002 and 2015 (inclusion criterion) was recorded and comparatively evaluated. Early postoperative outcome was characterized by general and specific complication rate indicating morbidity, mortality, and microbial colonization rate, in particular surgical site infection (SSI, according to CDC criteria). In addition, microbiological findings of swabs and cultures from all compartments as well as preoperative and perioperative parameters from patient records were retrospectively documented and used for statistical comparison in this systematic retrospective unicenter observational study (design). Results: In total, 192 cases with CA (68.1%) and 90 cases with CP (31.9%) met the inclusion criteria of this study. Surprisingly, there were similar specific complication rates of 45.3% (CA) vs. 45.6% (CP; p = 0.97) and in-hospital mortality, which differed only slightly at 3.65% (CA) vs. 3.3% (CP; p = 0.591); the overall complication rate tended to be higher for CA at 23.4% vs. 14.4% (CP; p = 0.082). Overall, potentially pathogenic germs were detected in 28.9% of all patients in CP compared to 32.8% in CA (p = 0.509), and the rate of SSI was 29.7% (CA) and 24.4% (CP; p = 0.361). In multivariate analysis, CA was found to be a significant risk factor for the development of SSI (OR: 2.025; p = 0.048); the underlying disease had otherwise no significant effect on early postoperative outcome. Significant risk factors in the multivariate analysis were also male sex for SSI and microbial colonization, and intraoperatively transfused red cell packs for mortality, general and specific complications, and surgical revisions. Conclusions: Based on these results, a partly significant, partly trending negative influence of the underlying disease CA, compared to CP, on the early postoperative outcome was found, especially with regard to SSI after PPPD. This influence is corroborated by the international literature.

RESUMEN

Introduction The position of finger immobilization after flexor tendon rupture repair is changed to the extended position to prevent flexion contracture of the interphalangeal (IP) joint. However, in Strickland's assessment, We believe that a reduction in TAF (total active flexion) affects the outcome and that extension fixation is not necessarily the primary focus. For example, there are management methods that swap the fixed position between day and night. It is assumed that some effect is sought by placing the fingers in the flexed position. That is, the method of fixation is currently selected at individual facilities through twists and turns; however, the indications and criteria for selecting finger fixation positions are ambiguous, and they are apparently subject to the experience of therapists. This study aimed to characterize follow-up outcomes of flexion and extension fixation after zones I and II flexor tendon rupture repair. Methods This nonrandomized controlled trial with historical controls included 25 patients with flexor tendon ruptures of 30 fingers. The flexion fixation group consisted of 12 patients (n=16 fingers) and the extension fixation group consisted of 13 patients (n=14 fingers). The group with flexion fixation comprised patients who slept with their injured fingers in the flexed position (intervention group). The group with extension was retrospectively selected between April 2017 and March 2019, who slept with their injured finger in the extended position (historical control group). Strickland assessments of the range of motion (ROM) of each joint at the conclusion of hand therapy, the ratio of total active motion of the repaired, to the healthy finger (%TAF), and IP joint extension limitation angles were compared using Mann-Whitney U tests. Ratios of excellent and good ratings based on the Strickland assessment were compared using Fisher exact tests. Result The results of the Strickland assessment showed excellent or good outcomes for 22 (73%) of 30 fingers, which was in line with our previous findings. Strickland ratings of excellent were achieved in seven (44%) of 16 fingers and four (28%) of 14 fingers in the groups with flexion and extension fixation, respectively. The outcomes for two (22%) of 16 fingers and seven (78%) of 14 fingers in the groups with flexion and extension fixation were, respectively, rated as good. The proportion of patients rated as excellent was significantly higher in the group with flexion than extension fixation (p=0.040). The %TAF and the active flexion angle of the distal interphalangeal (DIP) joint were higher in the group with flexion than extension fixation (p=0008 and p=0.025, respectively). Furthermore, the total angle of the IP joint limit of extension did not significantly differ between the groups. Conclusion Flexion fixation after flexor tendon rupture achieved an excellent Strickland rating and was more effective than extension fixation, especially in terms of the active flexion ROM of the DIP joint. Flexion fixation might be an alternative to extension fixation because the range of flexion should be greater and might provide a range of finger extension motion equivalent to that of extension fixation.

RESUMEN

BACKGROUND: The most difficult hernia surgery is the repair of the ventral hernia, which is caused by aberrant organ or tissue protrusions through the abdominal wall. Factors like obesity, smoking, and chronic medical conditions contribute to their formation. Surgical strategies have evolved from anatomical repair to mesh hernioplasty, with mesh placement playing a significant role in outcomes. The ideal anatomical location for mesh placement remains debated due to varying results. So, the objective of the study is to compare early postoperative complications, surgical site infection, and incidence of recurrence between sublay and onlay mesh placement repair of incisional hernias of <10 cm in diameter, at a tertiary hospital in Ranchi. METHODS:  This retrospective comparative study was conducted over a period of January 2022 to January 2024 at the Rajendra Institute of Medical Science, Ranchi, India. During the study period, 96 patients were operated on, and their demographic details, along with their position of mesh placement and postoperative complications (seroma formation, wound infection, postoperative hospital stays, and recurrence), were retrieved from the hospital data. Comparisons between onlay and sublay groups in terms of post-operative complications were made. RESULTS: Within the study period, a total of 96 patients were operated on for incisional hernia. In this study, 36 (37.5%) were male and 60 (62.5%) were female, with a male-to-female ratio of 0.6:1. Out of the total number of patients, 56 (58.4%) had a past history of emergency surgery. It was observed that there was a higher incidence of seroma formation in the onlay group compared to the sublay with a statistical significance p-value of 0.027. The incidence of wound infection was found to be statistically significant (p-value = 0.035) between the onlay and sublay groups. In a period of six-month follow-up, three patients of the total study population had an incidence of recurrent incisional hernia, of which two from the onlay group and one from the sublay group were present, and there was no statistical significance (p-value > 0.5). CONCLUSIONS: Based on our retrospective analysis, we can say that there is a lower incidence of postoperative complications and recurrence in sublay repair, along with a shorter postoperative hospital stay, making it a preferred method of repair over onlay.

RESUMEN

The increased availability of large clinical datasets together with increasingly sophisticated computing power has facilitated development of numerous risk prediction models for various adverse perioperative outcomes, including acute kidney injury (AKI). The rationale for developing such models is straightforward. However, despite numerous purported benefits, the uptake of preoperative prediction models into clinical practice has been limited. Barriers to implementation of predictive models, including limitations in their discrimination and accuracy, as well as their ability to meaningfully impact clinical practice and patient outcomes, are increasingly recognised. Some of the purported benefits of predictive modelling, particularly when applied to postoperative AKI, might not fare well under detailed scrutiny. Future research should address existing limitations and seek to demonstrate both benefit to patients and value to healthcare systems from implementation of these models in clinical practice.

RESUMEN

Arterial pressure monitoring and management are mainstays of haemodynamic therapy in patients having surgery. This article presents updated consensus statements and recommendations on perioperative arterial pressure management developed during the 11th POQI PeriOperative Quality Initiative (POQI) consensus conference held in London, UK, on June 4-6, 2023, which included a diverse group of international experts. Based on a modified Delphi approach, we recommend keeping intraoperative mean arterial pressure ≥60 mm Hg in at-risk patients. We further recommend increasing mean arterial pressure targets when venous or compartment pressures are elevated and treating hypotension based on presumed underlying causes. When intraoperative hypertension is treated, we recommend doing so carefully to avoid hypotension. Clinicians should consider continuous intraoperative arterial pressure monitoring as it can help reduce the severity and duration of hypotension compared to intermittent arterial pressure monitoring. Postoperative hypotension is often unrecognised and might be more important than intraoperative hypotension because it is often prolonged and untreated. Future research should focus on identifying patient-specific and organ-specific hypotension harm thresholds and optimal treatment strategies for intraoperative hypotension including choice of vasopressors. Research is also needed to guide monitoring and management strategies for recognising, preventing, and treating postoperative hypotension.

RESUMEN

OBJECTIVE: To investigate the risk factors influencing the postoperative outcome of arthroscopic rotator cuff repair (ARCR) and develop a nomogram prediction model. METHODS: A retrospective study was conducted on 302 patients who underwent ARCR from January 2019 to August 2023. Patients were categorized into two groups: a control group with 150 patients showing good recovery and an observation group with 152 patients exhibiting poor recovery. Relevant clinical data were collected and statistically analyzed. A nomogram model was constructed based on the results of multivariate logistic regression analysis. The model's accuracy, discrimination, and clinical utility were evaluated using calibration charts, AUC, c-index, and decision curve analysis. Internal validation was performed through self-random sampling. RESULTS: Univariate and multivariate regression analysis identified having a frozen shoulder, large rotator cuff tear, increased intraoperative rivet use, diabetes, and traumatic tear as predictive risk factors for poor postoperative outcomes. These factors were utilized to develop a clinical predictive nomogram. The nomogram model demonstrated excellent predictive accuracy for poor postoperative outcomes, both internally and externally. The unadjusted concordance index (C-index) was 0.793 [95% confidence interval (CI), 0.825-0.995]. The AUC for the nomogram was 0.788. Decision curve analysis revealed that the predictive model was clinically useful when the threshold probability ranged from 20 to 60%. CONCLUSION: The presence of a frozen shoulder, large rotator cuff tear, increased intraoperative rivet use, diabetes, and traumatic tear elevate the risk of suboptimal outcomes following ARCR. Conversely, having a higher preoperative University of California at Los Angeles Shoulder Rating Scale score mitigates this risk. This study introduces a novel nomogram model, exhibiting relatively high accuracy, which enables clinicians to precisely assess the postoperative adverse risk among patients with rotator cuff injuries requiring arthroscopic repair at the outset of treatment.

RESUMEN

Objective: Frailty, representing the physiological reserve and tolerance of the body, serves as a crucial evaluation index of the overall status of the older adults. This study aimed to investigate the prevalence of preoperative frailty and its impact on postoperative outcomes among older adults with lumbar degenerative disease in China. Patients and Methods: In this prospective study, a total of 280 patients aged 60 and above, diagnosed with lumbar degenerative disease and scheduled for surgical intervention were enrolled. The prevalence of frailty pre-surgery was evaluated using the Tilburg Frailty Indicator (TFI) and the modified Frailty Index 11 (mFI-11). The primary outcome was postoperative complication within 30 days post-surgery. The secondary outcomes were the length of hospital stay, hospital costs, reoperation within 30 days post-surgery and unplanned readmission within 30 days post-discharge. Both univariable and multivariable logistic regression were employed to screen and identify the risk factors predisposing patients to postoperative complications. Results: A total of 272 older adults were included in the study ultimately. The frailty detection rates of TFI and mFI-11 were 15.8% (43/272) and 10.7% (29/272) respectively. Thirty-four patients (12.5%) encountered complications. Significantly elevated rates of complications, prolonged hospital stays, increased hospital costs, and heightened readmission rates were observed in the frail group compared to the non-frail group (P<0.05). Univariable analysis showed that the potential factors related to complications are TFI, mFI-11 and albumin. Multivariable logistic regression revealed that TFI was an independent risk factor for postoperative complications (OR=5.371, 95% CI: 2.338-12.341, P < 0.001). Conclusion: Frailty was an independent predictor of postoperative complications in older adults undergoing lumbar fusion surgery. Frailty assessment should be performed in such patients to improve preoperative risk stratification and optimize perioperative management strategies.

RESUMEN

BACKGROUND: Surgical risk stratification is crucial for enhancing perioperative assistance and allocating resources efficiently. However, existing models may not capture the complexity of surgical care in Brazil. Using data from various healthcare settings nationwide, we developed a new risk model for 30-day in-hospital mortality (the Ex-Care BR model). METHODS: A retrospective cohort study was conducted in 10 hospitals from different geographic regions in Brazil. Data were analysed using multilevel logistic regression models. Model performance was assessed using the area under the receiver operating characteristic curve (AUROC), Brier score, and calibration plots. Derivation and validation cohorts were randomly assigned. RESULTS: A total of 107,372 patients were included, and 30-day in-hospital mortality was 2.1% (n=2261). The final risk model comprised four predictors related to the patient and surgery (age, ASA physical status classification, surgical urgency, and surgical size), and the random effect related to hospitals. The model showed excellent discrimination (AUROC=0.93, 95% confidence interval [CI], 0.93-0.94), calibration, and overall performance (Brier score=0.017) in the derivation cohort (n=75,094). Similar results were observed in the validation cohort (n=32,278) (AUROC=0.93, 95% CI, 0.92-0.93). CONCLUSIONS: The Ex-Care BR is the first model to consider regional and organisational peculiarities of the Brazilian surgical scene, in addition to patient and surgical factors. It is particularly useful for identifying high-risk surgical patients in situations demanding efficient allocation of limited resources. However, a thorough exploration of mortality variations among hospitals is essential for a comprehensive understanding of risk. CLINICAL TRIAL REGISTRATION: NCT05796024.

RESUMEN

Background Gastrointestinal malignancy surgeries are known to have a risk of postoperative complications. Preoperative nutritional status has been suggested as a potential predictor of postoperative outcomes, with low serum albumin levels utilized as a marker of malnutrition and increased risk of postoperative complications. This paper investigated the association between preoperative serum albumin levels and postoperative outcomes in patients undergoing colorectal cancer surgery. Methods This retrospective data-maintained study was based on all patients aged 18 years and above who underwent colorectal cancer surgery at King Abdulaziz Medical City, Riyadh, Saudi Arabia between 2015 and 2022. Results A total of 400 patients were included in the study. With an average age of 64.43 years. Males represented 254 (63%) of the patients, while females accounted for 146 (37%). Thirty percent of patients had hypoalbuminemia (i.e., albumin level below 35 g/L) before surgery. Among the sample, 112 (28%) experienced complications after surgery. The mean albumin level for patients who experienced postoperative complications was 30.46 g/L while patients without complications had a normal albumin level. As for the length of hospital stay, it was eight days for patients with a normal albumin level and 23 days for hypoalbuminemia patients. Conclusion In conclusion, preoperative hypoalbuminemia is associated with poor patient outcomes and can be utilized as a prognostic marker for patients in need of colorectal cancer surgery.

RESUMEN

Background: General anaesthesia is provided to more than 300 million surgical patients worldwide, every year. It is administered either through total intravenous anaesthesia, using only intravenous agents, or through inhalational anaesthesia, using volatile anaesthetic agents. The debate on how this affects postoperative patient outcome is ongoing, despite an abundance of published trials. The relevance of this topic has grown by the increasing concern about the contribution of anaesthetic gases to the environmental impact of surgery. We aimed to summarise all available evidence on relevant patient outcomes with total intravenous anaesthesia versus inhalational anaesthesia. Methods: In this systematic review and meta-analysis, we searched PubMed/Medline, Embase and Cochrane Central Register of Controlled trials for works published from January 1, 1985 to August 1, 2023 for randomised controlled trials comparing total intravenous anaesthesia using propofol versus inhalational anaesthesia using the volatile anaesthetics sevoflurane, desflurane or isoflurane. Two reviewers independently screened titles, abstracts and full text articles, and assessed risk of bias using the Cochrane Collaboration tool. Outcomes were derived from a recent series of publications on consensus definitions for Standardised Endpoints for Perioperative trials (StEP). Primary outcomes covered mortality and organ-related morbidity. Secondary outcomes were related to anaesthetic and surgical morbidity. This study is registered with PROSPERO (CRD42023430492). Findings: We included 317 randomised controlled trials, comprising 51,107 patients. No difference between total intravenous and inhalational anaesthesia was seen in the primary outcomes of in-hospital mortality (RR 1.05, 95% CI 0.67-1.66, 27 trials, 3846 patients), 30-day mortality (RR 0.97, 95% CI 0.70-1.36, 23 trials, 9667 patients) and one-year mortality (RR 1.14, 95% CI 0.88-1.48, 13 trials, 9317 patients). Organ-related morbidity was similar between groups except for the subgroup of elderly patients, in which total intravenous anaesthesia was associated with a lower incidence of postoperative cognitive dysfunction (RR 0.62, 95% CI 0.40-0.97, 11 trials, 3834 patients) and a better score on postoperative cognitive dysfunction tests (standardised mean difference 1.68, 95% CI 0.47-2.88, 9 trials, 4917 patients). In the secondary outcomes, total intravenous anaesthesia resulted in a lower incidence of postoperative nausea and vomiting (RR 0.61, 95% CI 0.56-0.67, 145 trials, 23,172 patients), less emergence delirium (RR 0.40, 95% CI 0.29-0.56, 32 trials, 4203 patients) and a higher quality of recovery score (QoR-40 mean difference 6.45, 95% CI 3.64-9.25, 17 trials, 1835 patients). Interpretation: The results indicate that postoperative mortality and organ-related morbidity was similar for intravenous and inhalational anaesthesia. Total intravenous anaesthesia offered advantages in postoperative recovery. Funding: Dutch Society for Anaesthesiology (NVA).

RESUMEN

Background: There is an increasing number of patients undergoing transfemoral aortic valve replacement (TAVR) with sedation. There is limited data assessing the efficacy and safety of the different types of sedative drugs. The objective was to compare two sedation techniques with regard to the need for vasoactive support, respiratory support, rate of conversion to general anesthesia (GA), common perioperative morbidities, intensive care unit (ICU) stay, and in-hospital mortality. Methods: A retrospective chart review study conducted among patients who underwent TAVR at a specialized cardiac center between January 2016 and December 2019. Data collection included patient diagnosis, preoperative comorbidities, intraoperative outcomes, and postoperative outcomes. Results: A total of 289 patients received local anesthesia; 210 received propofol infusion and 79 received a mixed propofol-ketamine infusion (Ketofol). The average age was 75.5 ± 8.9 years and 58.1% of the patients were females. Comparing propofol and ketofol groups, 31.2% and 34.2% of the patients required drug support, 7.6% and 6.3% required conversion to GA, 46.7% and 59.5% required respiratory support, respectively. These intraoperative outcomes were not significantly different between groups, P = 0.540, P = 0.707, and P = 0.105, respectively. In-hospital 30-day mortality in propofol and ketofol groups were 1.9% and 3.8%, respectively, P = 0.396. In both groups, the median post-procedure coronary care unit stay was 26 hours while post-procedure hospital stay was 3 days. Conclusions: There were no significant differences in perioperative or postoperative outcomes in TAVR patients receiving either propofol or ketofol. Propofol infusion, either alone or with ketamine, is reliable and safe, with minimal side effects.

RESUMEN

AIM: This study aimed to evaluate the effects of Fried Frailty Phenotype Questionnaire (FFPQ) scores on patient-reported postoperative outcomes. METHODS: This secondary analysis of a prospective observational study included 230 inpatients aged ≥65 years undergoing elective abdominal cancer surgery. The primary outcome was the Quality of Recovery-15 score on postoperative days 2, 4 and 7. The secondary outcomes included disability-free survival, defined as a 12-item World Health Organization Disability Assessment Schedule 2.0 score of <16% at 3 months. The associations of the FFPQ scores, ranging from 0 (robust) to 5 (frailty), with the primary and secondary outcomes were assessed using multiple analysis. RESULTS: After confirming the linearity of the FFPQ score for the outcomes, multiple regression analysis adjusted for prominent factors showed that the FFPQ score was a significant factor influencing the decrease in the Quality of Recovery-15 score on postoperative day 2 (ß = -2.67, 95% confidence interval -5.20, -0.15), 4 (ß = -3.54, 95% confidence interval -5.77, -1.30) and 7 (ß = -3.70, 95% confidence interval -5.75, -1.65). The adjusted odds ratio of the FFPQ score for disability-free survival postoperatively was 0.66 (95% confidence interval 0.49-0.90). CONCLUSIONS: Patients with higher FFPQ scores before elective major abdominal cancer surgery were likely to have lower postoperative Quality of Recovery-15 scores and poor disability-free survival.
