Quality of life before and after laparoscopic sleeve gastrectomy. A prospective cohort study.
BACKGROUND There is a lack of adequate prospect i ve data on quality -of-life ( QOL ) and its predictors in patients undergoing laparoscopic sleeve gastrectomy ( LSG ) .  The aim of this study was to assess longitudinal changes in QOL after LSG with the use of the obesity-specific Moorehead-Ardelt II question naire ( MAII ) and to identify clinical parameters associated with QOL outcome . METHODS Morbidly obese patients consecutively admitted for LSG , over a 30-month period , were prospect ively studied . QOL was assessed using the vali date d Greek version of the MAII question naire and a visual analogueue scale ( VAS ) , preoperatively and at 6 , 12 , and 24 months postoperatively . Anthropometric data and obesity-related co-morbidities were recorded . RESULTS A total of 111 patients with a mean age 36.8±9.2 years were included . Mean preoperative body mass index ( BMI ) was 49.1±7.5 kg/m2 . Percentage excess BMI loss ( % EBL ) was 51.1±14.9 , 64.2±17.9 and 66.4±18.0 at 6 , 12 , and 24 months , respectively . Postoperatively , all obesity-related co-morbidities were significantly improved . MAII score increased from -.40±1.30 preoperatively to 1.75±.83 , 2.18±.80 , and 1.95±.71 at 6 , 12 , and 24 months postoperatively ( trend P<.001 ) . Preoperative median ( interquartile range ) VAS was 3 ( 1 ) increasing to 9 ( 2 ) , 10 ( 1 ) , and 9 ( 1 ) at 6 , 12 , and 24 months postoperatively ( P<.001 ) . % EBL and reduction in obesity-related co-morbidities , especially resolution of diabetes and sleep apnea , correlated significantly with higher QOL during the course of the study . CONCLUSION LSG , a safe and effective bariatric operation , results in sustained weight loss and significant improvements in QOL . Both weight loss and amelioration of co-morbidities contribute to higher level of postsurgical QOL
