Nutritional markers following duodenal switch for morbid obesity.

Background: Laparoscopic duodenal switch with gastric reduction (LapDS) is a minimally invasive hybrid operation combining moderate intake restriction with moderate malabsorption for treatment of morbid obesity. In LapDS, both the quantity of food ingested and the efficiency of digestion are reduced.

Methods: A cohort of 589 sequential LapDS patients had laboratory studies drawn annually.

Laparoscopic technique for performing duodenal switch with gastric reduction.

Background: The duodenal switch procedure with gastric reduction (DS) is a hybrid procedure for morbid obesity that combines moderate intake restriction with moderate malabsorption. This report describes the laparoscopic hand-assisted technique for the duodenal switch procedure (LapDS).

Methods: Restriction is achieved via a greater curvature gastrectomy, reducing gastric capacity to 120 ml.
