Malignant Leakage After Sleeve Gastrectomy: Endoscopic and Surgical Approach

PURPOSE: Gastric leak occurs after sleeve gastrectomy (SG) in 2% of cases. Most staple-line disruptions (SLD) can be successfully treated with first-line endoscopic procedures. Less favorable situations may lead to more complex therapeutic strategies, like conversion to Roux-en-Y gastric bypass (RYGBP). The aim of our study is to predict the factors of endoscopic treatment failure and to assess the safety of conversion to RYGBP. METHODS: We included all patients treated in two centers of academic excellence (n = 100) between 2013 and 2017 who had a malignant SLD after SG. A "malignant" leakage met one of the following poor prognosis criteria suggested in the literature: unsuccessfully treated by the first-line endoscopic treatment; generalized peritonitis; anatomical anomalies; gastro-cutaneous or gastro-pleural fistula (GCF/GPF); or chronic leaks (\textgreater 4 weeks). RESULTS: No deaths occurred during the follow-up (20 ± 12 months). The endoscopy reported an anatomically abnormal gastric tube in 35 (35%) patients (stenosis [n = 21 (21%)], twist [n = 9 (9%)], or both [n = 5 (5%)]). We could maintain the SG in place in 92% of cases without stenosis, twist, or GCF/GPF. Conversion to RYGBP due to leakage was necessary in 37 (37%) patients. Stenosis, twist, or GCF/GPF significantly prevented healing in multivariate analysis (respectively: p = 0.020, OR = 0.17, and p \textless 0.001, OR = 0.07-logistic regression). CONCLUSION: Endoscopy is the treatment of choice for the management of chronic leaks after SG. The association of anatomical anomalies and GCF/GPF should lead to consideration of conversion to RYGBP

Effect of time to surgery in resectable pancreatic cancer: a systematic review and meta-analysis.

PURPOSE Achieving surgical resection is essential if patients with pancreatic ductal adenocarcinoma (PDAC) have a chance for cure. The objective of this study was to evaluate the effect of time to surgery on resection rates in patients with resectable PDAC. METHODS A systematic literature search was performed to identify studies reporting times to surgery and resection rates. Meta-regression models were then produced to assess the relationship between time to surgery and resection rates, using both intra- and inter-study comparisons. RESULTS A total of 21 studies were included, comprising n = 2171 patients, with a pooled resection rate of 76%. Intra-study meta-analysis of the five studies that reported comparisons between patients with vs. without preoperative biliary drainage (PBD) or with long vs. short delays to surgery found earlier surgery to be associated with a significantly higher rate of resection (pooled odds ratio 1.93, 95% CI: 1.25-2.97, P = 0.003). Inter-study meta-regression across all studies found a tendency for resection rates to decline with increasing time from CT or ERCP to surgery (gradient - 0.13 log-odds per week, 95% CI - 0.28, 0.03, P = 0.100), although this did not reach statistical significance, in part due to considerable heterogeneity between studies. CONCLUSION Pathways to reduce the time to surgery, primarily by avoiding PBD, demonstrate significantly greater resection rates. Early surgery, including avoidance of PBD, not only provides patients with the benefit of avoiding harm associated with PBD but also with a greater chance of undergoing resection
