Endoscopic sclerotherapy using sodium morrhuate has been used to treat patients with weight regain after Roux-en-Y gastric bypass whose presumed etiology is loss of restriction due to gastrojejunostomy dilation. Weight loss and stability have been demonstrated in several studies with short-term follow-up evaluation. This retrospective review evaluated all the patients who underwent sclerotherapy for a dilated gastrojejunostomy between 2007 and 2012. The study identified 48 patients with a mean follow-up period of 22 months (range 12-60 months). The mean age of these patients was 47.5 +/- A 10.5 years, and 92 % were women. The average weight loss from the primary procedure was 132.5 +/- A 54.82 lb, and the average weight regain from the lowest weight to the maximum weight before sclerotherapy was 46 +/- A 40.32 lb. The median number of sclerotherapy sessions was two (range 1-4). The pre-procedure mean gastrojejunostomy diameter was 20 +/- A 3.6 mm, and the mean volume of sodium morrhuate injected per session was 12.8 +/- A 3.7 ml. The average weight loss from sclerotherapy to the final documented weight was 3.17 +/- A 19.70 lb, which was not statistically significant. The following variables in the multivariate analysis were not associated with statistically significant weight loss: volume of sodium morrhuate, patient age, gastrojejunostomy diameter, number of sclerotherapy sessions, decrease in gastrojejunostomy diameter between the first and second sessions, and number of follow-up years. Weight stabilization or loss was achieved by 58 % of our cohort, with a mean weight loss of 15.9 +/- A 14.6 lb in this subgroup. The long-term follow-up evaluation of patients undergoing sclerotherapy of the gastrojejunostomy for weight regain after gastric bypass showed only a marginal weight loss, which was not statistically significant in our study population, although more than 50 % of the patients achieved weight loss or stabilization.
