BACKGROUND: Roux-en-Y gastric bypass (RYGB) is considered the gold standard for the treatment of morbid obesity. There is no consensus over ideal limb length when the bypass is created and published studies do not take into account the influence of the common limb (CL) on weight loss. The objective was to study the influence of the common limb after RYGB. The setting was the Virgen de la Arrixaca University Clinical Hospital in Murcia, Spain.
MATERIAL AND METHODS: This prospective study includes 151 patients undergoing laparoscopic RYGB surgery for morbid obesity. The patients were divided into 2 groups according to their body mass index. The small intestine (SI) was measured using micro forceps so that the percentage of common limb (%CL) could then be compared against the total SI in each patient. The percentage of excess weight loss (%EWL) in relation to the %CL was calculated at 3, 12, and 24 months. A series of tests was conducted simultaneously to analyze nutritional deficiencies and their relation to the %CL.
RESULTS: The total jejunoileal segment and the %CL in the groups of both obese and super-obese patients had no influence on the %EWL in either group for any of the periods studied. The patients with a %CL<50% had greater nutritional deficiencies in the follow-up period and required supplements and more frequent laboratory tests.
CONCLUSIONS: The %CL has no effect on weight loss in RYGB patients. A lower %CL is related to greater nutritional deficiencies.
