Background: Because anastomotic leaks after gastric bypass surgery can have devastating consequences for the patient, early detection is highly desirable. This and many other bariatric surgical centers have discontinued routine use of upper gastrointestinal contrast x-ray because of the lack of cost-effectiveness, discomfort to the patient, and the failure of the study to detect some leaks. We postulated that drain amylase levels from a juxta-anastomotic drain would detect the presence of salivary amylase and be a sensitive test for gastrojejunostomy leak.

We sought to define a rational approach to ventral hernia management in the gastric bypass patient in a university hospital setting.
Methods: We performed a retrospective, single-institution analysis of all patients who had undergone concomitant ventral hernia repair (VHR) during antecolic gastric bypass.
Background: The routine use of closed suction drains and upper GI (UGI) series has been used to aid in the diagnosis and management of gastrojejunal leak after gastric bypass as well as diagnose intra-abdominal bleeding.
Materials And Methods: 352 consecutive laparoscopic gastric bypass procedures were performed without the use of routine drains or post-operative UGI series.
Results: There were no adverse events related the lack of routine drains or UGI studies.
Background: Central venous access devices play an integral role in providing long-term venous access. Percutaneous and cut-down techniques have been used with varying complications.
Methods: Between January 1998 and July of 2001, 358 venous access devices were placed at Albert Einstein Medical Center in Philadelphia, Pennsylvania.
