Weight loss and quality of life after bariatric surgery: a study of 200 patients after vertical gastroplasty or adjustable gastric banding


Background and objectives:

Long term evaluation of bariatric surgery must include quality of life measurement.


Quality of life (QoL) was evaluated using the original Moorehead–Ardelt questionnaire for 200 patients operated for massive obesity in a single centre between 1994 and 2003. QoL and physical data were obtained by retrospective mail questionnaire. Surgical procedures were vertical-banded gastroplasty according to Mason (VBGM) and adjustable gastric banding (AGB) in 61 and 39% of patients, respectively. The aim of the study was to assess the nutritional outcome and QoL according to the procedure.


Overall, the body mass index (BMI) decreased from 50±8 kg/m2 before surgery to 35.2±7.5 kg/m2 at the time of the questionnaire. The percentage of weight loss was 28.8±12.2%. In the group treated with VBGM, the mean initial weight (P=0.003) and the percentage of weight loss (P<0.001) were significantly higher, and the QoL was better (P=0.003) than in the group treated with AGB. On the basis of the time spent since surgery, a regular weight loss was observed during the first 5 years, whereas weight subsequently increased over the five following years. Similarly, the total QoL score gradually improved during the first 5 years and worsened thereafter. However, it remained better than before surgery. A linear regression analysis showed a positive correlation between the percentage of weight loss and the QoL score (P<0.001).


This study suggests that the bariatric surgery, particularly the VBGM technique, improved the QoL of obese patients, at least in the first 5 years following surgery.
