The role of dumping syndrome in weight loss after gastric bypass surgery
Abstract
Background Roux-en-Y gastric bypass is the most commonly performed operation for the treatment of morbid obesity in the US. Dumping syndrome is an expected and desired part of the behavior modification caused by gastric bypass surgery; it can deter patients from consuming energy-dense food. In this study we assessed the role dumping has in weight loss and its relationship with the patient's eating behavior. Methods Fifty patients who underwent gastric bypass between January 2008 and June 2008 were enrolled. Two questionnaires, the dumping syndrome questionnaire and the Three-Factor Eating Questionnaire (TFEQ), were used to record the patients' responses. The diagnosis of dumping syndrome was based on the Sigstad scoring system, where a score of 7 and above was considered positive. TFEQ evaluated the patients' eating behavior under three scales: cognitive restraint, uncontrolled eating, and emotional eating. The results were analyzed with descriptive and parametric statistics where applicable. Results The prevalence of dumping syndrome was 42 %, with 66.7 % of the subjects being women. The nondumpers were observed to have a greater mean decrease in body mass index than the dumpers at 1 and 2 years (18.5 and 17.8 vs. 14.4 and 13.7 respectively). There was no definite relationship between the presence of dumping syndrome and the eating behavior of the patient. However, the cognitive restraint scores, greater than 80 %, were associated with an average decrease in BMI of 19 and 20…

Dumping syndrome is a common complication of esophageal, gastric or bariatric surgery.

Dumping syndrome has been reported to occur in approximately 20% of patients who undergo vagotomy with pyloroplasty, in up to 40% of patients after Roux-en-Y gastric bypass or sleeve gastrectomy, and in up to 50% of patients who undergo esophagectomy.

Weight loss after Roux-en-Y gastric bypass was not dependent on the presence of dumping symptoms.
“However, although it has previously been suggested that dumping symptoms might be essential for weight loss after bariatric surgery, a prospective series demonstrated that weight loss after Roux-en-Y gastric bypass was not dependent on the presence of dumping symptoms, and other studies suggest that some patients with dumping syndrome may exhibit weight gain (5,17,18).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
