Abstract
BACKGROUND: The incidence of complications following gastric bypass surgery has decreased markedly over the last 30 years; nevertheless, significant morbidity and mortality is still associated with this procedure. Much of the improved risk of this technique can be attributed to the numerous modifications that have taken place in its evolution. METHODS: We compared our series of 640 primary cases of vertical banded gastroplasty-Roux-en-Y gastric bypass (VBG-RGB), a form of gastric bypass, with gastric bypass series reported in the literature from 1966 to 1996. Incidences considered were those of subphrenic abscess, gastrointestinal leaks, obstruction of the excluded segment of gastrointestinal tract, splenectomy and death. RESULTS: The overall trend during the last 30 years has been a reduction in the rate of major complications. In our series, we had one major complication, a subphrenic abscess. This compares favorably with the incidence of major complications reported in the literature. CONCLUSIONS: The gastric bypass is a significantly safer operation today than three decades ago. We believe that the relatively low complication rate of VBG-RGB results from: (1) the anatomic location of the gastric pouch; (2) the type of stapling device used in its construction; (3) a pouch outlet restricted by a prosthetic band rather than a narrow anastomosis; and (4) the construction of a retrocolic, retrogastric Roux-en-Y gastrojejunal anastomosis.
