“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
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
“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

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

“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

Abstract: Leakage from the duodenal stump has been the most feared complication of the Billroth II reconstruction following gastric resection. The purpose of our study was to evaluate four methods of duodenal stump closure in 200 patients. One hundred and forty-seven (74%) patients had duodenal ulcers; 28 (14%) had gastric ulcers; and 25 (13%) had a variety of other inflammatory conditions. The most common indication for operation was acute hemorrhage (51%), followed by perforation (24%), intractability (15%), and obstruction (10%). Conventional duodenal closures were performed in 160 (80%) patients, Nissen’s closure in 25 (13%), Bancroft’s closure in 6 (3%), and tube duodenostomy in 9 (5%). Duodenal leaks occurred in four (2.5%) patients with conventional closures and in three (33%) patients with tube duodenostomies. No leaks occurred in patients with Nissen’s or Bancroft’s closures. The hospital mortality rate for the series was 9.5%; however, no patient who developed a duodenal leak died. We conclude that Nissen’s and Bancroft’s closures were safe and effective, but that tube duodenostomy did not reliably prevent uncontrolled leakage.Continue reading
