Vertical ring gastroplasty for morbid obesity. Five year experience with 1,463 patients

Abstract

Vertical gastroplasty is a safer and simpler operation than gastric bypass for morbid obesity, but to produce permanent long-term weight loss, a permanent support is needed for the outlet of the newly created gastric pouch in vertical gastroplasty. The most important finding in this study of 1,463 patients with vertical gastroplasties was the development of a safe and practical use of a Silastic ring to permanently support the outlet. Using an uncovered Silastic ring, erosion of the ring has not been observed and long-term weight loss of 36.7 percent of original weight or 63.4 percent of excess weight has been obtained, which is equivalent to that reported for gastric bypass or other gastric reduction procedures. In addition, lower mortality and lower morbidity rates have been achieved than those reported in studies using other gastric reduction methods. Silastic ring vertical gastroplasty with an uncovered ring is the safest and most effective of the gastric reduction procedures in our experience.
