“The purpose of this study was to compare the rates of small bowel obstruction, anastomotic complications, and wound infections between stapled and handsewn closures of loop ileostomies. The diverting loop ileostomy is a commonly used stoma, often employed to diminish the consequences of an anastomotic leak in low colorectal anastomoses, ileal pouch-anal anastomoses, and in situations where reversible patient factors increase the risk of an anastomotic dehiscence. They are also used to divert the fecal stream in the event of an anastomotic leak and, occasionally, in severe fistulizing perianal disease.”Continue reading

Guideline on the role of endoscopy in the evaluation and management of choledocholithiasis
“The aim of this document is to provide evidence-based recommendations for the endoscopic evaluation and treatment of choledocholithiasis based on rigorous review and synthesis of the contemporary literature, using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. The GRADE framework is a system for rating the quality of evidence and strength of recommendations that is comprehensive and transparent and has been recently adopted by the American Society for Gastrointestinal Endoscopy (ASGE). This document addresses the following 4 clinical questions:”
1. “What is the diagnostic utility of EUS versus MRCP to confirm choledocholithiasis in patients at intermediate risk of choledocholithiasis?
2. In patients with gallstone pancreatitis, what is the role of early ERCP?
3. In patients with large choledocholithiasis, is endoscopic papillary dilation after sphincterotomy favored over sphincterotomy alone?
4. What is the role of ERCP-guided intraductal therapy (EHL and laser lithotripsy) in patients with large and difficult choledocholithiasis?”
Efficacy of UGI and CT in Bariatric Surgery
“According to our results, a CT scan triggered by clinical suspicion must be considered the first-line procedure to detect a postoperative leak following primary sleeve gastrectomy or Roux-en-Y gastric bypass.”Continue reading
Predicting risk of anastomotic leakage after gastrectomy
A multivariate analysis showed the following adverse risk factors for AL: age > 65 years, hemoglobin < 8.0 g/dL and malnourishment. A multivariable model for AL showed a strong optimism-adjusted discrimination (concordance index, 0.675).Continue reading
ABI staging for acute bowel ischemia: Imaging findings
“Acute bowel ischemia (ABI) can be life threatening with high mortality rate. The radiologist plays a central role in the initial diagnosis and preventing progression to irreversible intestinal ischemic injury or bowel necrosis. The most single imaging findings described in the literature are either non-specific or only present in the late stages of ABI, urging the use of a constellation of features to reach a more confident diagnosis”Continue reading
High impact complications after Whipple procedure
Mirrielees JA, et al. Pancreatic Fistula and Delayed Gastric Emptying Are the Highest-Impact Complications After Whipple. J Surg Res. 2020 Jun;250:80-87.
Full-text for Emory users.
Results: About 10,922 patients undergoing pancreaticoduodenectomy were included for analysis. The most common postoperative complications were DGE (17.3%), POPF (10.1%), incisional SSI (10.0%), and organ/space SSI (6.2%). POPF and DGE were the only complications that demonstrated sizable effects for all clinical and resource utilization outcomes studied. Other complications had sizable effects for only a few of the outcomes or had small effects for all the outcomes.Continue reading
Retained Gastric Antrum Syndrome
Dumon K, Dempsey DT. (2019). Postgastrectomy Syndromes. Shackelford’s Surgery of the Alimentary Tract, 8th ed.: 719-734.
“Hypergastrinemia after distal gastrectomy can be caused by gastrinoma or retained antrum. In the latter there is residual antral tissue left in continuity with the duodenal stump after gastric resection with Billroth II anastomosis. The G cells in this retained antral tissue are not exposed to luminal acid, resulting in continuous secretion of gastrin and intense stimulation of acid production by parietal cells in the proximal gastric remnant. The exposure of the unbuffered jejunum to this high acid level at the Billroth II GJ results in marginal ulcer (see Fig. 62.12B ).Continue reading
