Abstract
INTRODUCTION: Gastric emptying (GE) and food tolerance (FT) can be altered after Roux-en-Y gastric bypass (RYGB) has been performed, especially when it involved the use of a restrictive mechanism (such as a silastic ring). AIM: To assess GE and FT in patients who underwent banded (BRYGB) or non-banded Roux-en-Y gastric bypass (RYGB). METHODS: Forty-seven BRYGB patients and 47 RYGB patients underwent gastric emptying scintigraphy (GES) and FT assessment (by means of a questionnaire) between 6 months and 2 years postoperatively. RESULTS: GES was performed on average 11.7 ± 5.0 months (6 to 24) postoperatively. T½ medians (time taken for the gastric radioactivity to decrease to half of the original value in the gastric pouch) in the RYGB and BRYGB groups were 48.7 min (40.6-183.0 min) and 56.3 min (41.1-390.9 min), respectively (p = 0.031). The median of total questionnaire scores was 24 points (18-27) in the RYGB group and 20 points (13-27) in the BRYBG group (p < 0.001). CONCLUSIONS: The band (silastic ring) delays GE time and does not affect patient satisfaction or food tolerance to vegetables, bread, or rice, but does affect tolerance to the intake of meat, salad, and pasta. The best tolerated foods are vegetables, salad, and fish. Banded patients are more likely to regurgitate and vomit. Gastric emptying does not affect FT.
