Weight changes after vertical banded gastroplication.
OBJECTIVE
This study assessed the patterns of weight change in response to surgical treatment for obesity.


METHODS
Vertical Banded Gastroplication (VBG) was performed during the period 1994-2000. Patients were required to follow a liquid diet (800 kcals)for 12 weeks before surgery. The same diet plus a multivitamin capsule (Forceval) was followed for 12 weeks postoperatively, after which normal foods were introduced. Data from 23 patients, 16 women and 7 men, aged 33-63 years (mean, SD; 42 +/- 8 yrs), with BMI from 38 to 69 kg/m2 (52.5 +/- 8.1 kg/m2) at the time of the surgery were available for analysis. Follow up was 3 to 7 years (mean 4 years).


RESULTS
An initial weight loss of 44.4 +/- 24.3 kg (min 11.5, max 110.5 kg) was reached during the first two years (mean BMI decrease 15.8 kg/m2). However a regain in weight (36% of the initial weight loss = 5.6 kg/m2) up to 3 to 7 years after surgery was usual. Average annual regain was 13.6 kg (n=17), 9.45 kg (n=11) and 0.8 kg (n=8) during the 3rd, 4th and 5th year after surgery). Five participants reached a BMI below 30 but only one, BMI < 25, has maintained all the weight loss after 5years.


CONCLUSIONS
Weight lossfollowing VBG ceased after twoyears with a subsequent substantial weight regain. Auxiliary therapies to counteract weight regain are necessary after VBG.
