Increased Gastric Retention Capacity Assessed by Scintigraphy after APC Treatment of Dilated Gastrojejunal Anastomosis

摘要

BackgroundWeight regain occurs in about 20% of patients after Roux-en-Y gastric bypass (RYGB). Studies have reported that in most cases this regain is associated with dilatation of the gastrojejunal anastomosis. To correct this dilatation, one of the methods used is the application of argon plasma coagulation (APC).
