RESUMO
Introducción. La ileostomía derivativa de protección se realiza con el objetivo de proteger la anastomosis intestinal después de una resección colorrectal. Esta resección intestinal es el procedimiento extendido más frecuentemente realizado en pacientes con cáncer de ovario, con el fin de lograr una citorreducción completa. Conocer las indicaciones, el uso, las técnicas y las complicaciones de las ileostomías es importante para los grupos multidisciplinarios que tratan estas pacientes. Métodos. Se realizó una búsqueda en PubMed vía Medline y una revisión narrativa actualizada de los principales hallazgos sobre las indicaciones, las técnicas quirúrgicas, complicaciones y el uso de la ileostomía derivativa en el cáncer de ovario. Resultados. El uso de la ileostomía derivativa en cáncer de ovario sigue siendo un tema controvertido. Hasta la fecha, ni la ileostomía de derivación ni la ileostomía fantasma se han asociado con una reducción en la incidencia de la fuga anastomótica, pero ambas técnicas podrían disminuir su gravedad. Conclusión. La ileostomía de derivación en cáncer de ovario se usa para proteger una anastomosis distal tras una resección intestinal, en caso de fuga anastomótica si no se ha realizado una ostomía previa o en caso de obstrucción intestinal.
Introduction. Protective diverting ileostomy is performed with the aim of protecting the intestinal anastomosis after a colorectal resection. This intestinal resection is the most frequently performed extended procedure in patients with ovarian cancer, in order to achieve complete cytoreduction. Knowing the indications, use, techniques and complications of ileostomies is important for multidisciplinary groups that treat these patients. Methods. We conducted a search in PubMed via Medline and an updated narrative review of the main findings on the indications, surgical techniques, complications and use of diverting ileostomy in ovarian cancer. Results. The use of diverting ileostomy in ovarian cancer remains a controversial issue. To date, neither diverting ileostomy nor ghost ileostomy have been associated with a reduction in the incidence of anastomotic leak, but both techniques could decrease its severity. Conclusion. The diverting ileostomy in ovarian cancer is used to protect a distal anastomosis after intestinal resection, in case of anastomotic leak if a previous ostomy has not been performed or in case of intestinal obstruction.

OBJECTIVES: To investigate the incidence of intravalvular leak after aortic valve replacement with the Inspiris Resilia valve. DESIGN: This study was a retrospective chart review. SETTING: This study used data from a single tertiary care academic center. PARTICIPANTS: A total of 81 patient charts and echo images were reviewed. INTERVENTIONS: All patients underwent an aortic valve replacement using the Inspiris Resilia valve. Pediatric patients and patients receiving an aortic valve conduit were excluded. MEASUREMENTS AND MAIN RESULTS: Transesophageal echocardiography (TEE) images were reviewed independently by 2 echocardiographers for the incidence and severity of intravalvular leak after Inspiris Resilia valve placement. Outpatient follow-up imaging was then compared to intraoperative findings. Valve size and mean gradients were documented as well. Of the 81 TEEs that were reviewed, 56 (69.1%) were found to have a strut leak at the time of implantation. Among these 56 cases, 30 were classified as trace regurgitation, 21 as mild regurgitation, and 5 as moderate regurgitation. Only 1 case necessitated a return to cardiopulmonary bypass owing to persistent intravalvular leak. Follow-up transthoracic echocardiography reports were available for 50 of the patients with no persistent leaks. CONCLUSIONS: This pattern of intravalvular leak is unique to the Inspiris Resilia valve and is commonly found in the intraoperative period. While many hypotheses exist for the origin of this leak, the exact mechanism is unclear. Given the high frequency of this postprocedure finding, it is essential that intraoperative echocardiographers be able to distinguish this clinically insignificant leak based on its origin, severity, and direction and to provide appropriate recommendations to our surgical colleagues.

Purpose: Laparoscopic sleeve gastrectomy (LSG) is one of the most common surgical procedures worldwide for the treatment of morbid obesity. Blake-type drains are widely used in this procedure despite the lack of clear evidence regarding their benefits in the diagnosis and treatment of common postoperative complications such as gastric suture line leak (GSLL) and postoperative bleeding (PB). Materials and Methods: A retrospective descriptive study with prospective case registry was conducted, analyzing all patients who underwent LSG between January 2012 and December 2022 at a high-volume center. Our primary outcome was to evaluate the role of drains for diagnosis and treatment of GSLL and PB in LSG. Our secondary outcome was to determine drain related surgical site infection (DRSSI) rate. Results: A total of 335 LSG were performed in the studied period. In all patients one abdominal drain was placed during surgery. Six GSLL (1.79%) and 5 PB (1.49%) were recorded. Drain placement did not prove to ensure early diagnosis or conservative management of GSLL or PB after LSG. Furthermore, an incidence of DRSSI of 4.1% (14 patients) was found. Conclusion: In our study, no clear diagnostic or therapeutic benefits of the systematic use of drains for GSLL or PB in LSG was found; but drain use did show a considerable rate of DRSSI, which must be taken into consideration prior to considering drain systematic use. While no randomized prospective trials have been performed, the retrospective data does not support drain systematic use.
RESUMO
Massive bleeding due to rupture of hypogastric artery pseudoaneurysm is an exceptional complication of colorectal anastomotic leakage. A 41-year-old woman with history of rectal cancer surgery, who debuted with massive rectorrhagia and hypovolemic shock due to rupture of a hypogastric artery pseudoaneurysm as a late complication of a colorectal anastomosis leak. The ruptured hypogastric artery pseudoaneurysm should be taken into account in the differential diagnosis of patients with massive rectorrhagia and history of colorectal anastomosis leak. Endovascular embolization is considered the first-line treatment.

PURPOSE: Coloanal anastomosis with loop diverting ileostomy (CAA) is an option for low anterior resection of the rectum, and Turnbull-Cutait coloanal anastomosis (TCA) regained popularity in the effort to offer patients a reconstructive option. In this context, we aimed to compare both techniques. METHODS: PubMed, Cochrane, and Scopus were searched for studies published until January 2024. Odds ratios (RRs) with 95% confidence intervals (CIs) were pooled with a random-effects model. Statistical significance was defined as p < 0.05. Heterogeneity was assessed using the Cochran Q test and I2 statistics, with p-values inferior to 0.10 and I2 >25% considered significant. Statistical analysis was conducted in RStudio version 4.1.2 (R Foundation for Statistical Computing). Registered number CRD42024509963. RESULTS: One randomized controlled trial and nine observational studies were included, comprising 1,743 patients, of whom 899 (51.5%) were submitted to TCA and 844 (48.5%) to CAA. Most patients had rectal cancer (52.2%), followed by megacolon secondary to Chagas disease (32.5%). TCA was associated with increased colon ischemia (OR 3.54; 95% CI 1.13 to 11.14; p < 0.031; I2 = 0%). There were no differences in postoperative complications classified as Clavien-Dindo ≥ IIIb, anastomotic leak, pelvic abscess, intestinal obstruction, bleeding, permanent stoma, or anastomotic stricture. In subgroup analysis of patients with cancer, TCA was associated with a reduction in anastomotic leak (OR 0.55; 95% CI 0.31 to 0.97 p = 0.04; I2 = 34%). CONCLUSION: TCA was associated with a decrease in anastomotic leak rate in subgroups analysis of patients with cancer.

There are no standard management protocols for the treatment of bile leak (BL) after liver transplantation. The objective of this study is to describe treatment options for BL after pediatric LT. METHODS: Retrospective analysis (January 2010-March 2023). VARIABLES STUDIED: preoperative data, status at diagnosis, and postoperative outcome. Four groups: observation (n = 9), percutaneous transhepatic cholangiography (PTC, n = 38), ERCP (2), and surgery (n = 27). RESULTS: Nine hundred and thirty-one pediatric liver transplantation (859 LDLT and 72 DDT); 78 (8.3%) patients had BL, all in LDLT. The median (IQR) peritoneal bilirubin (PB) level and fluid-to-serum bilirubin ratio (FSBR) at diagnosis was 14.40 mg/dL (8.5-29), and 10.7 (4.1-23.7). Patients who required surgery for treatment underwent the procedure earlier, at a median of 14 days (IQR: 7-19) versus 22 days for PTC (IQR: 15-27, p = 0.002). PB and FSBR were significantly lower in the observation group. In 11 cases, conservative management had resolution of the BL in an average time of 35 days, and 38 patients underwent PTC in a median time of 22 days (15-27). Twenty-seven (34.6%) patients were reoperated as initial treatment for BL in a median time of 17 days (1-108 days); 25 (33%) patients evolved with biliary stricture, 5 (18.5%) after surgery, and 20 (52.6%) after PTC (p = 0.01). CONCLUSION: Patients with BL who were observed presented significantly lower levels of PB and FSBR versus those who underwent PTC or surgery. Patients treated with PTC presented higher rates of biliary stricture during the follow-up.

Pancreatic leaks occur when a disruption in the pancreatic ductal system results in the leakage of pancreatic enzymes such as amylase, lipase, and proteases into the abdominal cavity. While often associated with pancreatic surgical procedures, trauma and necrotizing pancreatitis are also common culprits. Cross-sectional imaging, particularly computed tomography, plays a crucial role in assessing postoperative conditions and identifying both early and late complications, including pancreatic leaks. The presence of fluid accumulation or hemorrhage near an anastomotic site strongly indicates a pancreatic fistula, particularly if the fluid is connected to the pancreatic duct or anastomotic suture line. Pancreatic fistulas are a type of pancreatic leak that carries a high morbidity rate. Early diagnosis and assessment of pancreatic leaks require vigilance and an understanding of its imaging hallmarks to facilitate prompt treatment and improve patient outcomes. Radiologists must maintain vigilance and understand the imaging patterns of pancreatic leaks to enhance diagnostic accuracy. Ongoing improvements in surgical techniques and diagnostic approaches are promising for minimizing the prevalence and adverse effects of pancreatic fistulas. In this pictorial review, our aim is to facilitate for radiologists the comprehension of pancreatic leaks and their essential imaging patterns.
RESUMO
Background: For individuals with pure aortic regurgitation (AR), transcatheter aortic valve implantation (TAVI) is cautiously recommended only for those with a high or prohibitive surgical risk. We aimed to describe the results of a case series of transcatheter implantation of a balloon-expandable aortic valve bioprosthesis (BEV) for the treatment of noncalcified native valve AR. Methods: From February 2022-November 2022, we performed TAVI in patients with severe pure AR. Cases were indicated on the basis of symptoms, high/prohibitive surgical risk, or patient refusal of conventional treatment. Results: Five patients underwent successful TAVI. The mean age was 81.9 ± 6.6 years, 3 (60%) female and 5 (100%) in NYHA class III or IV. The baseline echocardiogram showed an ejection fraction of 49.0 ± 10.6% and left ventricular end-systolic diameter 28.5 ± 4.7â mm/m². The average area of the aortic annulus was 529.1 ± 47.0mm² and the area oversizing index was 17.6 ± 1.2%. In the 30-day follow-up, there were no cases of prosthesis embolization, annulus rupture, stroke, acute myocardial infarction, acute renal failure, hemorrhagic complication or death. One patient required a permanent pacemaker and another had a minor vascular complication. The clinical follow-up were 19.8 months (16.7-21.8). During this period, all patients remained alive and in NYHA class I or II. One of the patients developed a moderate paravalvular leak. Conclusion: TAVI with a BEV proved to be safe and effective in this small case series of patients with noncalcified native valve AR in a follow-up longer than 1 year.
RESUMO
Introduction: The anastomotic leak (AL) is one of the most feared complications of colorectal surgery, since it is associated with a high rate of morbidity, mortality, length of hospital stay and cost of care. Our aim was to determine the risk factors associated with anastomosis leak in colorectal cancer patients who underwent surgical resection with anastomosis. Methods: A multicentre observational, analytical, retrospective and case-control study was carried out. For each case, two controls were included from three national hospitals from Lima, Peru during the period 2021-2022. To determine the degree of association, multivariate logistic regression model was carried out. Results: A total of 360 patients were included, 120 from each hospital. The mean age of the population was 68.03 ± 14.21 years old. The majority were 65 years old or older (66.1%), 52.8% were female, and 63.3% had clinical stage III. The 40% of the patients had albumin levels lower than 3.5 g/dL. Regarding the surgery, 96.4% were elective, 68.9% underwent open approach, and 80.8% had an operative time of more than 180 minutes. Most of them had right colon cancer (50.8%). In the multivariate analysis, a significant association was found with the age variable (OR = 2.48; 95%CI:1.24-4.97), clinical tumour level (OR = 2.71; 95%CI:1.34-5.48), American Society of Anesthesiologists (ASA) Score (OR = 3.23; 95%CI:1.10-9.50), preoperative serum albumin (OR = 22.2; 95%CI:11.5-42.9). Conclusion: The most important independent risk factors associated with AL among patients with colorectal cancer were pre-operative such as lower preoperative serum albumin levels, followed by a higher ASA Score, clinical-stage III-IV, and an age ≥65 years old.
RESUMO
BACKGROUND AND OBJECTIVES: This study evaluates the Tri-Staple™ technology in colorectal anastomosis. METHODS: Patients who underwent rectosigmoidectomy between 2016 and 2022 were retrospectively evaluated and divided into two groups: EEA™ (EEA) or Tri-Staple™ (Tri-EEA). The groups were matched for age, sex, American Society of Anesthesiologists (ASA), and neoadjuvant radiotherapy using propensity score matching (PSM). RESULT: Three hundred and thirty-six patients were included (228 EEA; 108 Tri-EEA). The groups were similar in sex, age, and neoadjuvant therapy. The Tri-EEA group had fewer patients with ASA III/IV scores (7% vs. 33%; p < 0.001). The Tri-EEA group had a lower incidence of leakage (4% vs. 11%; p = 0.023), reoperations (4% vs. 12%; p = 0.016), and severe complications (6% vs. 14%; p = 0.026). There was no difference in complications, mortality, readmission, and length of stay. After PSM, 108 patients in the EEA group were compared with 108 in the Tri-EEA group. The covariates sex, age, neoadjuvant radiotherapy, and ASA were balanced, and the risk of leakage (4% vs. 12%; p = 0.04), reoperation (4% vs. 14%; p = 0.014), and severe complications (6% vs. 15%; p = 0.041) remained lower in the Tri-EEA group. CONCLUSION: Tri-Staple™ reduces the risk of leakage in colorectal anastomosis. However, this study provides only insights, and further research is warranted to confirm these findings.

Introduction. Perforated peptic ulcer remains one of the critical abdominal conditions that requires early surgical intervention. Leakage after omental patch repair represents one of the devastating complications that increase morbidity and mortality. Our study aimed to assess risk factors and early predictors for incidence of leakage. Methods. Retrospective analysis of data of the patients who underwent omental patch repair for perforated peptic ulcer in the period between January 2019 and January 2022 in Mansoura University Hospital, Egypt. Pre, intra and postoperative variables were collected and statistically analyzed. Incriminated risk factors for leakage incidence were analyzed using univariate and multivariate analysis. Results. This study included 123 patients who met inclusion criteria. Leakage was detected in seven (5.7%) patients. Although associated comorbidities (p=0.01), postoperative intensive care unit admission (p=0.03), and postoperative hypotension (p=0.02) were significant risk factors in univariate analysis, septic shock (p=0.001), delayed intervention (p=0.04), preoperative hypoalbuminemia (p=0.017), and perforation size >5mm (p= 0.04) were found as independent risk factors for leakage upon multivariate analysis. Conclusion. Delayed presentation in septic shock, preoperative hypoalbuminemia, prolonged perforation, operation interval, and large perforation size > 5mm were detected as independent risk factors for leakage. Postoperative tachypnea and tachycardia with increased levels of C-reactive protein and total leucocytic count are alarming signs for incidence of leakage
Introducción. La úlcera péptica perforada es una de las afecciones abdominales críticas que requiere una intervención quirúrgica temprana. La fuga después de la reparación con parche de epiplón representa una de las complicaciones más devastadoras, que aumentan la morbilidad y la mortalidad. Nuestro estudio tuvo como objetivo evaluar los factores de riesgo y los predictores tempranos de fugas. Métodos. Análisis retrospectivo de los datos de los pacientes sometidos a reparación con parche de epiplón por úlcera péptica perforada, en el período comprendido entre enero de 2019 y enero de 2022, en el Hospital Universitario de Mansoura, Egipto. Se recogieron y analizaron estadísticamente variables pre, intra y postoperatorias. Los factores de riesgo asociados a la incidencia de fugas se analizaron mediante análisis univariado y multivariado. Resultados. Este estudio incluyó 123 pacientes que cumplieron con los criterios de inclusión. Se detectó fuga en siete (5,7 %) pacientes. Aunque las comorbilidades asociadas (p=0,01), el ingreso postoperatorio a la unidad de cuidados intensivos (p=0,03) y la hipotensión postoperatoria (p=0,02) fueron factores de riesgo en el análisis univariado, el shock séptico (p=0,001), el retraso en la intervención (p=0,04), la hipoalbuminemia preoperatoria (p=0,017) y el tamaño de la perforación mayor de 5 mm (p=0,04) se encontraron como factores de riesgo de fuga independientes en el análisis multivariado. Conclusión. Se detectaron como factores de riesgo independientes de fuga la presentación tardía en shock séptico, la hipoalbuminemia preoperatoria, la perforación prolongada, el intervalo operatorio y el tamaño de la perforación mayor de 5 mm. La taquipnea posoperatoria y la taquicardia con niveles elevados de proteína C reactiva y recuento leucocitario total son signos de alarma sobre la presencia de fuga.

Introducción: La hipotensión intracraneal espontánea es un síndrome causado por la disminución del volumen de líquido cefalorraquídeo consecuencia de su fuga al espacio extradural. Aunque la ICHD-3 proporciona un alto nivel de especificidad diagnóstica, esta enfermedad puede manifestarse de forma atípica. Hasta en un 30% no es posible establecer el punto de escape, pero con el refinamiento de los exámenes de imágenes este porcentaje se ha reducido a un 15%-20%. Actualmente, su manejo no se encuentra estandarizado y las recomendaciones se basan en evidencia de limitada calidad metodológica, además de la variabilidad de protocolos entre distintos centros. Desarrollo En esta revisión actualizamos los procedimientos diagnósticos y terapéuticos. Por un lado, analizamos el rol de la resonancia nuclear magnética de encéfalo y médula espinal completa como primer paso diagnóstico y, por otro lado, señalamos los exámenes destinados a determinar la fuga de líquido cefalorraquídeo. Tal es el caso de la mielo-resonancia, la mielo-tomografía computarizada, tanto estándar, dinámica y por sustracción digital, además de la cisternografía con 111-Indium-DPTA. Sin embargo, determinar cuál de estos exámenes es el óptimo es objeto de debate. Lo mismo ocurre con el tratamiento: reposo; parche sanguíneo epidural a ciegas, parche guiado por fluoroscopia o tomografía computarizada, parche de fibrina; o cirugía. Conclusiones Se requiere de una mayor investigación, especialmente con trabajos multicéntricos controlados, para una mejor comprensión de la fisiopatología, el diagnóstico por imágenes, los enfoques terapéuticos y evaluación objetiva de los resultados clínicos. Solo así se establecerán pautas diagnósticas y de tratamiento validadas.
Introducction: Spontaneous intracranial hypotension is a syndrome caused by decreased CSF volume secondary to its leakage into the extradural space Although ICHD-3 provides a high level of diagnostic specificity, manifestations may be atypical, making diagnosis challenging. The site of leakage may be undetermined in point Up to 30% of cases, although with recent refinement of imaging, this percentage has been reduced to 15-20%. Currently, management is not standardized and recommendations are based on inconclusive evidence, with variability of protocols between centres. Development. In this review, we update diagnostic and therapeutic procedures. We analyse the role of whole brain and spinal cord MRI as a first investigation and review tests aimed at determining cerebrospinal fluid leakage, such as MRI myelography, conventional CT myelography, dynamic CT myelography, and digital subtraction CT myelography, as well as 111-Indium-DPTA cisternography. Determining optimal use of these investigations remains a matter of debate. The same is true for treatment: rest, blind epidural blood patch, fluoroscopy or CT-guided epidural blood patch, fibrin patch and surgery are discussed. Conclusión: Further research, especially multicentre controlled studies, is required to improve understanding of pathophysiology, diagnostic imaging, therapeutic approaches and to objectively assess clinical outcomes. Only then will diagnostic and treatment guidelines be evidence-based.
RESUMO
La filtración de la esófagoyeyuno anastomosis (FEYA) es una de las complicaciones más graves tras una gastrectomía total, ya que se asocia a un aumento de la morbimortalidad quirúrgica. El manejo óptimo de la FEYA aún es controversial, existiendo cada vez más opciones mínimamente invasivas, especialmente endoscópicas. El objetivo de la presente revisión es comparar la evidencia científica publicada y actualizada referente al tratamiento médico, endoscópico y quirúrgico de una FEYA y sus resultados a corto y largo plazo además de proponer un algoritmo de manejo que permita orientar la práctica clínica. Finalmente se presenta la experiencia nacional en relación a los avances presentados en los últimos años en torno manejo clínico de FEYA.
Leakage of the esophagojejunostomy (LEY) is one of the most serious complications after total gastrectomy, as it is associated with increased surgical morbidity and mortality. The optimal management of LEY is still controversial, with increasing minimally invasive options, especially endoscopic ones. The aim of this review is to compare the published and updated scientific evidence regarding the medical, endoscopic and surgical treatment of LEY and its short and long-term results, in addition to propose a management algorithm that allows guiding clinical practice. Finally, the national experience is presented in relation to the advances presented in recent years regarding clinical management of LEY.

Introduction: Endoscopic endonasal approaches are the procedures of choice for medial tumors in the cranial base given their safety and effectiveness. Repair of the cranial base constitutes a high challenge. Objective: To evaluate the effectiveness of constructing a cranial base reconstruction barrier in patients with cranial base tumors operated on by endoscopic endonasal approaches. Method: A descriptive study was carried out, which included 70 patients from the Hermanos Ameijeiras Hospital operated on for cranial base tumors using endoscopic endonasal approaches. A cranial base repair barrier was constructed to isolate the sinonasal and intracranial compartments. The efficiency of the repair barrier was determined through clinical and endoscopic aspects. Aspects were defined to be evaluated in relation to the vitality of the repair barrier with the use of fibrin rich in platelets and leukocytes. Results: An efficient repair barrier was evident in 98.6 percent. In relation to the state of vitality of the barrier, adhesion and granulation were observed in 98.6 percent of patients, while angiogenesis was observed in 97.1 percent. The incidence of postoperative cerebrospinal fluid leak was only 1.4 percent. Conclusions: The present study shows the positive effect of the construction of an efficient repair barrier of the cranial base in endoscopic endonasal approaches with a significant reduction in cerebrospinal fluid leak and its complications(AU)

Background: Colon leakage score (CLS) was developed for risk prediction of anastomotic leak (AL) in the left-sided colorectal surgery. Although the risk factors for leakage are well known and accepted by the surgical community, an accurate forecast of AL is still a difficult task. Objective: The study aims to apply the CLS in patients undergoing left-sided colorectal surgery. Methods: Retrospective study in patients with the left-sided colorectal surgery and primary anastomosis without diverting stoma. CLS was calculated in patients, who were classified in AL and NO-AL groups. Predictive value of CLS was evaluated by receiver operator characteristic. Correlation between CLS and AL was determined. 208 patients (55% male, mean age 59 years) were included in the study. Results: Overall, AL was 7.2%. Mean CLS of all patients was 7.2 ± 3.2 (0-17). Patients with AL had a higher CLS (11.8 ± 2.3) than NO-AL patients (6.8 ± 3) (p = 0.0001). The area under the curve for the prediction of AL by CLS was 0.898 ([CI] 0.829-0.968, p = 0.0001). A CLS of 8.5 had 93% sensitivity and 72% specificity. There was a statistically significant odds ratio for CLS and AL (0.58: [CI] 0.46-0.73, p = 0.0001). Conclusion: CLS is a useful tool to predict AL in the left-sided colorectal surgery.
Antecedentes: La puntuación de fugas de colon (CLS) se desarrolló para la predicción del riesgo de fuga anastomótica (AL) en la cirugía colorrectal del lado izquierdo, con la finalidad de obtener un pronóstico preciso. Objetivo: Este estudio tiene el objetivo de aplicar el CLS en pacientes con cirugía colorrectal de lado izquierdo. Método: Estudio retrospectivo en pacientes con cirugía colorrectal izquierda y anastomosis primaria sin estoma de derivación. Se calculó el CLS en los pacientes, los cuales fueron clasificados en los grupos con AL y sin AL. Resultados: La media del CLS de todos los pacientes fue de 7.2 ± 3.2 (0-17). Los pacientes con AL tenían un CLS más alto (11.8 ± 2.3) que los pacientes sin AL (6.8 ± 3) (p = 0.0001). El área bajo la curva para la predicción de la AL mediante el CLS fue de 0.898 (intervalo de confianza (CI) 0.829-0.968; p = 0.0001). Un CLS de 8.5 tuvo una sensibilidad del 93% y una especificidad del 72%. Además, se obtuvo un Odds Ratio con una diferencia estadísticamente significativa para el CLS y AL (0.58; CI 0.46-0.73; p = 0.0001). Conclusión: La CLS es una herramienta útil para predecir la AL en la cirugía colorrectal del lado izquierdo.
RESUMO
Incidental durotomies are frequent complications of spine surgery associated with cerebrospinal fluid (CSF) leak-related symptoms. Management typically involves prolonged bed rest to reduce CSF pressure at the durotomy site. However, early ambulation may be a safer, effective alternative. PubMed, Web of Science, Embase, Cochrane, and Scopus were systematically searched for studies comparing early ambulation (bed rest ≤ 24 h) with prolonged bed rest (> 24 h) for patients with incidental durotomies in spine surgeries. The outcomes of interest were CSF leak, hypotensive headache, additional surgical repair, pseudomeningocele, and pulmonary complications. Systematic reviews and meta-analysis were performed following the Cochrane Handbook for Systematic Reviews of Interventions. We included a total of 704 patients from 6 studies. There was a significant reduction in the incidence of pulmonary complications (RR 0.23; 95% CI 0.08-0.67; p = 0.007) in the early mobilization group. The incidence of CSF leak (RR 1.34; 95% CI 0.83-2.14; p = 0.23), hypotensive headache (RR 0.72; 95% CI 0.27-1.90; p = 0.50), additional repair surgery (RR 1.29; 95% CI 0.76-2.2; p = 0.35), and pseudomeningocele (RR 1.29; 95% CI 0.20-8.48; p = 0.79) did not differ significantly. In patients with incidental durotomy following spinal surgery, early mobilization was associated with a lower incidence of pulmonary complications as compared with prolonged bed rest. There was no significant difference between groups in terms of CSF leak, need for additional repair, pseudomeningocele, and hypotensive headache.

OBJECTIVE: To determine the efficacy of serum procalcitonin (PCT) and C-reactive protein (CRP) in the early diagnosis of anastomotic leak (AL) in patients undergoing colorectal surgery. METHOD: Diagnostic test in a tertiary care hospital. Patients who did not have preoperative measurements of PCT and CRP were excluded. Those with postoperative infection not related to AL were eliminated. The diagnostic efficacy measures were sensitivity (Sn), specificity (Sp), positive (PPV) and negative (NPV) predictive values, positive (LR+) and negative (LR-) likelihood ratios, and area under the receiver operating characteristic curve (AUROC). RESULTS: Thirty-nine patients were analyzed; six had AL (15.4%). PCT and CRP increased on the second postoperative day, only in patients with AL. The cut-off points at the second postoperative day were 1.55 ng/mL for PCT and 11.25 mg/L for CRP. The most efficacious test was PCR at second postoperative day (AUROC: 1.00; Sn: 100%; Sp: 96.7%; PPV: 85.7%; NPV: 100%; LR+: 33.0). CONCLUSIONS: CRP at second postoperative day was the most effective test in the early diagnosis of AL in patients undergoing colorectal surgery, with a cut-off point lower than that reported in the international literature.
OBJETIVO: Determinar la eficacia de la procalcitonina (PCT) y la proteína C reactiva (PCR) séricas en el diagnóstico de fuga anastomótica (FA) en los pacientes sometidos a cirugía colorrectal. MÉTODO: Prueba diagnóstica en un hospital de tercer nivel. Se excluyeron los pacientes que no tuvieron mediciones preoperatorias de PCT y PCR. Se eliminaron los que cursaron con infección posoperatoria no relacionada con FA. Las medidas de eficacia diagnóstica fueron sensibilidad (S), especificidad (E), valores predictivos positivo (VPP) y negativo (VPN), razones de verosimilitud positiva (RV+) y negativa (RV−), y área bajo la curva característica operativa del receptor (AUROC). RESULTADOS: Se analizaron 39 pacientes, de los cuales 6 (15.4%) tuvieron FA. La PCT y la PCR aumentaron al segundo día posoperatorio solo en los pacientes con FA. Los puntos de corte al día 2 fueron 1.55 ng/ml para PCT y 11.25 mg/l para PCR. La prueba más eficaz fue la PCR al día 2 (AUROC: 1.00; S: 100%; E: 96.7%; VPP: 85.7%; VPN: 100%; RV+: 33.0). CONCLUSIONES: La PCR en el segundo día posoperatorio fue la prueba más eficaz en el diagnóstico temprano de FA en los pacientes sometidos a cirugía colorrectal, con un punto de corte inferior a lo reportado en la literatura internacional.

Background: Patients with anterior skull base fractures after traumatic brain injury have a high risk of cerebrospinal fluid leak through the nostrils. Timely and appropriate management is important, avoiding complications. The "HP protocol" for surgical treatment was developed. Objectives: To communicate the utility of the "HP protocol" in the management of the anterior skull base cerebrospinal fluid leak. Methods: Retrospective cross-sectional study; patients ≥ 15 years old with a diagnosis of nasal cerebrospinal fluid leak after traumatic brain injury, who were admitted at the hospital from 1/1/2016 to 8/31/2021 and required surgery. Included 28 patients, p value Ë0.05 (statistically significant). Results: 96.4% men, mostly young adults with mild traumatic brain injury; 82.1% presented early cerebrospinal fluid leak. All required frontal transcranial repair, in 67.9% it was bilateral. Repair before 7 days was in 39.3%, 7-21 days in 46.4%, and after 21 days in 14.3%. Use of continuous lumbar drainage: preoperative 10.7%, intraoperative 60.7%, postoperative 46.4%. In 89.3%, the location of the intraoperative cerebrospinal fluid leak was consistent with the CT scan. Since 2020, the management of the cerebrospinal fluid leak was systematized. The recurrence was 10.7% before 2020; after it was 0% and associated with low Glasgow and onset of cerebrospinal fluid leak 7 days after traumatic brain injury (p<0.05). Complications: meningitis 28.6%, seizure 25%, anosmia 14.3%, high tension pneumocephalus 7.1% and abscess 3.6%. Cerebrospinal fluid leak mortality: 3.6%. Cure 96.4%. Conclusions: The application of the "HP Protocol" had satisfactory results. The post traumatic brain injury nasal cerebrospinal fluid leak recurrence rate was 0%
