Association of super-super-obesity and male gender with elevated mortality in patients undergoing the duodenal switch procedure.

Background: Previous studies have reported that risk factors for elevated mortality after Roux-en-Y gastric bypass include male gender, as well as a very elevated BMI. The present study was aimed at determining whether these same risk factors applied to patients undergoing the duodenal switch (DS) operation.

Materials And Methods: A retrospective chart review was performed of a cohort of 385 patients who underwent DS.

Beneficial effects of humidified, warmed carbon dioxide insufflation during laparoscopic bariatric surgery: a randomized clinical trial.

Background: Recent data has shown that the use of warmed, humidified carbon dioxide (CO2) insufflation during laparoscopic surgery may be associated with better outcomes.

Methods: We performed a randomized, doubleblind, prospective controlled clinical trial of 30 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP). Patients were randomized into 2 groups.
