Emergency room visits after laparoscopic Roux-en-Y gastric bypass for morbid obesity.
Patients can be symptomatic after laparoscopic Roux-en-Y gastric bypass because of either surgical complications or physiologic changes and adjustment to the new anatomy. The aim of this study was to evaluate the factors that could influence the rate of postoperative emergency room admissions (ERAs) and the clinical implication of these visits for patients who have undergone laparoscopic Roux-en-Y gastric bypass. ⋯ Our results suggest that the rate of potential ERAs should not be disregarded. A prolonged operative time and early postoperative complications were significant predictors for late ERAs. Abdominal pain with or without vomiting was the most common presenting symptom. Most patients can be treated conservatively.

Accuracy of upper gastrointestinal swallow study in identifying strictures after laparoscopic gastric bypass surgery.
Stricture at the gastrojejunal anastomosis after Roux-en-Y gastric bypass is a significant sequela that often requires intervention. The diagnosis of stricture is usually established by a recognized constellation of symptoms, followed by contrast radiography or endoscopy. The purpose of this report was to evaluate the accuracy of contrast swallow studies in excluding the diagnosis of gastrojejunal stricture. ⋯ The results of our study have shown that a positive upper GI swallow study is 100% specific for the presence of stricture. However, the sensitivity and negative predictive value of upper GI swallow studies were poor, making this modality unsatisfactory in definitively excluding the diagnosis of gastrojejunal stricture.
