Perforated duodenal ulcer after laparoscopic gastric bypass.

A patient with a history of a laparoscopic gastric bypass presented with a perforated duodenal ulcer. The ulcer was laparoscopically oversewn, and an omentoplasty was performed. Postoperatively, a broad spectrum antibiotic and a proton pump inhibitor were administrated. Several questions arise regarding the diagnosis and treatment of duodenal ulcers after gastric bypass. What are the diagnostic tools to detect a duodenal ulcer, and how should Helicobacter pylori be diagnosed after gastric bypass? The key question is whether the bypassed stomach should be resected as a definitive treatment for complicated duodenal ulcers.

Roux-en-Y gastric bypass as a re-do procedure for failed restricive gastric surgery.

BACKGROUND: Gastric restrictive procedures such as laparoscopic gastric banding or vertical banded gastroplasty show, at longer follow up, more and more failures and complications. This study focuses on the results of Roux-en-Y gastric bypass procedure (RYGBP) done as a re-do procedure, both after a technically failed restrictive procedure or when the restrictive procedure failed to obtain substantial weight loss. METHODS: We reviewed data concerning the postoperative complications and weight loss of 36 patients undergoing re-do surgery for failed restrictive procedures. RESULTS: Over a period of two years, 36 patients with a mean age of 40.9 years were converted to a RYGBP. Median time to conversion was 4.9 years, median follow up after conversion was 6.6 months. Early postoperative complications (less than 30 days postoperatively) were noted in 11 patients (30%). A greater number of early complications were noticed in group A (technical complications) compared to group B (insufficient weight loss) (39% vs. 22%). Late postoperative complications were seen in six patients (16%). In this relatively short follow up period we noticed a drop in body mass index (BMI) from a mean of 38.8kg/m(2) to 30.9 kg/m(2) with a mean excess body weight loss (EBWL) of 33.1% after the re-do procedure. Body mass index decreased from a mean preoperative value of 37.6kg/m(2) to 28.9 kg/m(2) in group A patients with an EBWL 36%, while group B patients had a change in BMI from 40.1kg/m(2) to 32.9 kg/m(2) with a mean EBWL of 30%. CONCLUSION: Based on the literature, we can presume that restrictive surgery for morbidly obese patients will require many reoperations in the future. The standard operation of choice is RYGBP. In our study this procedure showed a higher, but not significantly early morbidity rate when the indication for re-do surgery was a technical complication of the initial procedure.

Gastric perforation after cardiopulmonary resuscitation: review of the literature.

The risk of complications of cardiopulmonary resuscitation (CPR) does not outweigh the benefit of a successful restoration of a spontaneous circulation. Despite the frequent occurrence of gastric distension (caused by air entering the stomach because of too forceful and/or too quick rescue breathing), there are few reports of massive gastric distension causing gastric rupture and pneumoperitoneum after CPR. We reviewed all 67 case reports of gastric perforation that have been reported after CPR. Although uncommon, this review stresses the need to consider this potentially lethal complication after initial successful resuscitation.
