RESUMEN

BACKGROUND: The way that pain is assessed in the PACU could impact on postoperative pain and analgesic consumption. However, there is currently no evidence to support this speculation. The authors hypothesised that using a comfort scale reduces postoperative opioid consumption when compared with a standard numerical rating scale (NRS) to evaluate pain in the PACU. METHODS: In this cluster-randomised trial, patients were assessed using either a comfort scale (comfort group) or a pain NRS (NRS group). The primary outcome was the opioid consumption in the PACU. The main secondary outcomes were postoperative pain, nausea and vomiting, length of stay in the PACU, and satisfaction. RESULTS: Of 885 randomised patients, 860 were included in the analysis. Opioid consumption in the PACU was comparable in the comfort and NRS groups (median [interquartile range [IQR] 0 (0-5) vs 0 (0-6); P=0.2436), irrespective of the type of surgical procedure. The majority of patients did not need any postoperative opioid (59% in the comfort group and 56% in the NRS group, P=0.2260). There was no difference in postoperative pain, nausea and vomiting, time to reach an Aldrete score ≥9 after extubation, and global satisfaction. CONCLUSIONS: Using a comfort scale to assess pain in the PACU did not spare any opioid compared with use of a standard NRS. Further studies focusing on patients at risk of increased postoperative opioid consumption are necessary. CLINICAL TRIAL REGISTRATION: NCT05234216.

RESUMEN

BACKGROUND: Sclerosing Encapsulating peritonitis (SEP) is a rare chronic fibro-inflammatory disease of the peritoneum. The aetiology can be either primary or secondary. The knowledge around this topic is poor. CASE PRESENTATION: Based on the report of a 64-year-old man suffering from intestinal obstruction and its management with a final diagnosis of primary SEP, herein we review the literature concerning this specific entity of primary SEP and its challenge in both diagnosis and treatment. CONCLUSION: whereas SEP is a rare entity, imagery is helpful to make the diagnosis.

RESUMEN

Introduction: Biliary duct injury (BDI) is a serious complication during cholecystectomy. Perioperative cholangiography (POC) has recently been generating interest in order to prevent BDI. However, the current literature (including randomized controlled trials) cannot conclude whether POC is protective or not against the risk of BDI. The aim of our study was to investigate whether POC could demonstrate earlier BDI and which criteria are required to make that diagnosis. Methods: We performed a retrospective study between 2005 and 2018 in our French tertiary referral center, which included all patients who had presented following BDI during cholecystectomy. Results: Twenty-two patients were included. Nine patients had POC, whereas 13 did not. When executed, POC was interpreted as normal for three patients and abnormal for six. In this latter group, only two cases had a BDI diagnosed intraoperatively. In other cases, the interpretation was not adequate. Conclusion: BDIs are rare but may reduce patients' quality of life. Our study highlights the surgeon's responsibility to learn how to perform and interpret POC in order to diagnose and manage BDIs and potentially avoid catastrophic consequences.

RESUMEN

The introduction of biological or absorbable synthetic meshes has provided an alternative to conventional repair for incisional hernia. The ability to predict the development of complications after hernia surgery is important, as it guides surgical planning and patient management. This retrospective study assessed whether the postoperative C-reactive protein (CRP) level can predict complications after incisional hernia repair using biological mesh reinforcement. Patients who underwent incisional hernia repair surgery using biological meshes between February 2009 and February 2015 were screened for study inclusion. Patients included in the study were divided into two groups: those with and without postoperative complications. The two groups were analysed based on sex, surgical operation, length of intensive care unit stay (ICU), complications and mortality. Laboratory values, including white blood cell (WBC) count and CRP levels, were determined preoperatively and up to postoperative day (POD) 10. Postoperative complications requiring further management occurred in 32 of the 60 patients (53.3%). Among 47 patients, the mean CRP and WBC levels were 6.6 mg/L and 9.073 G/L in the group without complications vs. 141.0 mg/L, 16.704 G/L in the group with complications (p < 0.001). Patients with complications also had a longer ICU stay (10.1 vs. 0.6 days, p < 0.0001). A cut-off was 101 mg/L and offered 80.00% sensitivity (IC 61.43% to 92.29) and 95.24% specificity (76.18% to 99.88%) for postoperative complication. The rate of postoperative complications before POD10 was 95% in the group with CRP > 100 mg/L vs. 46% in the group with CRP < 100 mg/L (p = 0.000372). A high postoperative CRP level (> 100 mg/L) up to POD10 may serve as a predictor of postoperative complications in patients undergoing incisional hernia using biological meshes.

RESUMEN

BACKGROUND: Biological acellular porcine dermis mesh, such as Permacol™, has been used since 2009 to treat abdominal incisional hernias in a septic context. This study investigated the risk factors for incisional hernia recurrence after biological mesh augmentation. RESULTS: Over a period of 6 years from February 2009 to February 2015, 68 patients underwent surgery. The mesh was placed intraperitoneally with closure of the anterior fascia in 27 cases (39.7%). The biological mesh was placed in the retromuscular pre-fascial plane in 1 case (1.5%) and pre-aponeurotic plane in 1 case (1.5%). Closure of the anterior fascia was not achieved in 39 cases, including 20 cases in which the mesh was placed intraperitoneally (intraperitoneal bridging group, 29.4%) and 19 cases in which the mesh was placed between the edges of the fascia (inlay bridging group, 27.9%). There were 37 cases of postoperative surgical site infections (54.4%), and Clavien-Dindo morbidity staging indicated stage I-II and III-IV complications in 19.1% and 44.1% of the cases, respectively. The recurrence rate was 61.8%, and the mortality rate was 0%. The rate of recurrence was significantly lower in the «fascia approximated¼ group (37%), p = 0.001). Univariate analyses of risk factors for procedural failure indicated an increased risk of recurrence in cases of postoperative surgical site infections, complications of Clavien-Dindo grade III or higher, an absent fascial closure in front of the mesh (OR = 8.69), an operating time longer than 180 min, and a VHWG score higher than 2. After logistic regression, the risk factors for recurrence were postoperative infections (OR = 6.2), placement of bridged biological mesh (OR = 22.3), and postoperative morbidity grade III or higher (OR = 16.7). CONCLUSIONS: Patients with postoperative surgical site infections are at an increased risk for recurrence, and bridged mesh placements lack efficacy. Overall, this study challenges the purported advantage of biologics in treating incisional hernia repairs.

RESUMEN

Hartmann's reversal procedures are often fraught with complications or failure to recover. This being a fact, it is often difficult to select patients with the optimal indications for a reversal. The post-recovery morbidity and mortality rates in the literature are heterogeneous between 0.8 and 44%. The identification of predictive risk factors of failure of such interventions would therefore be very useful to help the practitioner in his approach. Given these elements, it was important to us to analyze the practice of two French university hospitals in order to highlight such risk factors and to allow surgeons to select the best therapeutic strategy. We performed a bicentric observational retrospective study between 2010 and 2015 that studied the characteristics of patients who had undergone Hartmann surgery and were subsequently reestablished. The aim of the study was to identify factors influencing morbidity and postoperative mortality of Hartmann's reversal. Primary outcome was complications within the first 90 postoperative days. 240 patients were studied of which 60.4% were men. The mean age was 69.48 years. The median time to reversal was 8 months. 79.17% of patients were operated as emergency cases where the indication was a diverticular complication (39.17%). Seventy patients (29.2%) underwent a reversal and approximately 43% of these had complications within the first 90 postoperative days. The mean age of these seventy patients was 61.3 years old and 65.7% were males. None of them benefited from a reversal in the first three months. We identified some risk factors for morbidity such as pre-operative low albuminemia (p = 0.005) and moderate renal impairment (p = 0.019). However, chronic corticosteroid use (p = 0.004), moderate renal insufficiency (p = 0.014) and coronary artery disease (p = 0.014) seem to favour the development of anastomotic fistula, which is itself, a risk factor for mortality (p = 0.007). Our study highlights an important rate of complications including significant anastomotic fistula after Hartmann's reversal. Precarious nutritional status and cardiovascular comorbidities should clearly lead us to reconsider the surgical indication for continuity restoration.

RESUMEN

We report the case of a 17-year-old male admitted to our academic hospital with massive rectal bleeding. Since childhood he had reported recurrent gastrointestinal bleeding and had two exploratory laparotomies 5 and 2 years previously. An emergency abdominal computed tomography scan, gastroscopy and colonoscopy, performed after hemodynamic stabilization, were considered normal. High-dose intravenous proton pump inhibitor (PPI) therapy was initiated and bleeding stopped spontaneously. Two other massive rectal bleeds occurred 8 h after each cessation of PPI which led to a hemostatic laparotomy after negative gastroscopy and small bowel capsule endoscopy. This showed long tubular duplication of the right colon, with fresh blood in the duplicated colon. Obscure lower gastrointestinal bleeding is a difficult medical situation and potentially life-threatening. The presence of ulcerated ectopic gastric mucosa in the colonic duplication explains the partial efficacy of PPI therapy. Obscure gastrointestinal bleeding responding to empiric anti-acid therapy should probably evoke the diagnosis of bleeding ectopic gastric mucosa such as Meckel's diverticulum or gastrointestinal duplication, and gastroenterologists should be aware of this potential medical situation.

RESUMEN

This clinical study reports that blood levels of the pro-inflammatory mediator platelet-activating factor (PAF) did not change in colorectal cancer patients. In contrast, plasma levels of two enzymatic activities, one implicated in PAF production (i.e. phospholipase A2) and one in PAF degradation (i.e. PAF acetylhydrolase activity) were significantly elevated.

RESUMEN

The lipid mediator platelet-activating factor (PAF) plays a role in cancer. We investigated its presence in human colon carcinoma by assessing the levels of tissue phospholipase A(2) (PLA(2), the key enzyme in the generation of the lyso-PAF precursor), lyso-PAF, PAF and acetylhydrolase activity (AHA, the key enzyme in PAF degradation) in colorectal cancer patients and by correlating them with Dukes' classification. The results highlighted that the tumour tissues of Dukes' A and B patients had significantly higher PLA(2), lyso-PAF, PAF and AHA levels as compared with nontumour tissues. Dukes' C patients had higher PLA(2), lyso-PAF and AHA levels but unchanged PAF. Dukes' D patients had higher AHA levels but unchanged PLA(2), lyso-PAF and PAF. A pathophysiological role for PAF is suggested in human colon carcinoma.
