Patient satisfaction and results of vertical banded gastroplasty and gastric bypass

Morbid obesity contributes to many health risks, including physical, emotional, and social problems. Various surgical treatments for morbid obesity have developed and have so far met with good results. This study compares vertical banded gastroplasty (VBG) with gastric bypass (GBP) and the patients' satisfaction with either procedure.

Between April 1993 and July 1997, 63 bariatric surgical procedures were performed at Eisenhower Army Medical Center. Of those, complete follow-up was obtained for 29 patients. The parameters evaluated included age, preoperative and postoperative weights, body mass index (BMI), type of surgery, complications, and the patient's level of satisfaction.

The study group consisted of 27 women and 2 men. The average preoperative weight was 135 kg, and the average preoperative BMI was 48.3 kg/m2. There were 17 VBGs and 12 GBPs performed. The average total weight loss was 45.1 kg. The average postoperative BMI was 33.2 kg/m2. There were no statistically significant differences in weight loss between VBG and GBP. Four of 17 patients had complications after VBG, and three of 12 patients had complications after GBP. After VBG, 94.1 % of patients were satisfied, and after GBP, 100% were satisfied. Twenty-seven of 28 patients stated that they would have the surgery again.

There were no statistically significant differences in weight loss or complications after VBG or GBP. Patient satisfaction was high after both procedures. Therefore, bariatric surgery is important in the treatment of appropriately selected, morbidly obese patients.
