Vertical banded gastroplasty: is obesity worth it?
Obesity is a public health issue of major concern for the United States and other developed nations. In the last several decades, bariatric surgery has developed as a means of treating morbid obesity. Vertical banded gastroplasty (VBG) is an attractive procedure because it has fewer side effects than other forms of bariatric surgery and maintains physiological continuity of the gut. VBG was performed in 36 patients at a rural community hospital from 1982-1990. There was only one intraoperative complication necessitating splenectomy and two early postoperative complications--gastric leak and marginal stress ulcer--necessitating reexploration. Twenty-five patients were available for follow-up, at which time they were an average of 6.4 years out of surgery. Two of these patients had died, both from cardiac arrest months or years after VBG. The remainder had gone from a preoperative average of 86.7% over ideal weight according to 1983 Metropolitan Life insurance Tables to 54.5% over ideal weight. Mean BMI for this group had changed from 41.2 preoperatively to 34.7 at follow-up. Success was defined as weight loss to < 60% over ideal or BMI < 35, removing the individual from the morbidly obese category. According to this criteria, VBG provided successful weight loss in 72% of subjects in the follow-up group. Weight loss results may have been biased as a significant number of patients were lost to follow-up and may have constituted failures. In general, most individuals did not make concomitant changes in diet or sedentary life-style which would have supported weight loss effected by VBG. Moreover, regain of weight was progressive and possibly inexorable. Nearly all individuals nonetheless reported great satisfaction with their surgery. VBG is a viable option in the treatment of morbid obesity, but criteria for success needs to be better defined in order to determine whether the procedure is "worth it."
