title: Comparative study of laparoscopic sleeve gastrectomy with and without partial enterectomy and omentectomy.
abstract: BACKGROUND
  Laparoscopic sleeve gastrectomy (LSG) is a novel bariatric surgical procedure that constitutes the first-stage procedure of laparoscopic Roux-en-Y gastric bypass in high-risk patients, the long-term results of which are unknown. Our objective was to establish whether partial enterectomy and omentectomy are necessary in addition to LSG to achieve weight loss in obese patients. The setting was a case series in a provincial hospital.
  
  
  METHODS
  A total of 40 obese patients (29 women and 11 men) were separated into 2 equal groups according to patient choice. Group 1 underwent LSG alone, and group 2 underwent LSG plus partial enterectomy and omentectomy. The partial enterectomy left the first 100 cm of the jejunum and the last 200 cm of the ileum. The data were collected during the follow-up examinations, performed at 1, 3, 6, and 12 months postoperatively.
  
  
  RESULTS
  The body mass index loss (BMIL) was 3.9 ± .5 kg/m(2) and 9.4 ± 1.3 kg/m(2) at 1 and 12 months in group 1, respectively. The BMIL was 4.5 ± .9 kg/m(2) and 10.4 ± 1.9 kg/m(2) at 1 and 12 months in group 2, respectively. At 1 and 12 months postoperatively, the percentage of excess body weight loss was 32.2% ± 12.6% and 81.5% ± 20.4% in group 1 and 35.5% ± 10.5% and 83.8% ± 24.5% in group 2, respectively. Except for the BMIL at 1 month after surgery, no significant differences were found in the BMIL or percentage of excess body weight loss.
  
  
  CONCLUSIONS
  LSG with and without partial enterectomy and omentectomy in our study was an effective method of bariatric surgery, but they did not differ in their effect on weight loss. However, the long-term effect of weight loss with LSG alone or combined with partial enterectomy and omentectomy needs additional study.
