Background:
The sleeve gastrectomy is a surgical technique to treat morbid obesity by both restrictive and probably hormonal action. Originally developed as a first stage to gastric bypass, it is more and more performed as a sole procedure. Therefore it is important to report results on weight loss and reduction in co-morbidity.
Methods:
A consecutive series of 74 morbid obese patients were evaluated. Parameters were operative variables, complications, weight loss and the need for medication for co-morbidity at least six months postoperatively.
Results:
Six procedures included the removal of a band and twice a vertical banded gastroplasty was performed previously. Median operating time diminished over time to 71 min. Three procedures were converted into open approach. Major complications were rhabdomyolysis (2), bleeding (2) and leakage (4). Four days was the mean hospital stay. The median follow-up was 12 months (range 6-33). The median percentage of excess weight loss was 49.6% (range 22-96%EWL). The median loss in BMI points was 23.1% (range 9-50%BMIL). Three quarters of the patients were able to diminish or stop their medication for diabetes, hypertension and hyperlipedemia.
Conclusion:
The laparoscopic gastric sleeve is effective in reduction of both weight and co-morbidity and has potential as a sole procedure. Patient's selection is, however, recommendable for initial surgical experience and longer follow-up will be necessary.
