CSENDES J, Attila et al. Horizontal gastroplasty with Roux en Y anastomosis in morbidly obese patients. Preliminary results . Rev. méd. Chile [online]. 1999, vol.127, n.8, pp.953-960. ISSN 0034-9887.

Background: Morbidly obese subjects have a high incidence of complications. The poor results of dietary treatments, has prompted the search of new therapies for obesity and among these, surgical procedures. Aim: To report the long term results of horizontal gastroplasty with Roux en Y anastomosis in morbidly obese subjects. Patients and methods: Fifty patients with an initial body mass index of 41.3 ± 6 kg/m2 have been subjected to a horizontal gastroplasty with Roux en Y anastomosis. During the study period, surgical techniques were modified, reducing the gastric pouch size, adding a truncal vagotomy, cholecystectomy, and increasing the length of the Roux en Y loop from 70 to 100 cm. Twenty five patients have been followed for two years. Results: There was no operative mortality and one patient had an anastomotic leak that required 35 days of hospitalization. During follow up, in one patient, the stapled suture line loosened. After two years of follow up, weight decreased from 112 ± 19 to 77.2 ± 14 kg. Conclusions: Horizontal gastroplasty with Roux en Y anastomosis achieved an adequate weight loss with a low rate of complications in this group of morbidly obese subjects.
