Results of Laparoscopic Sleeve Gastrectomy

Background: In Iran, the type and main cause of obesity is different than in western society. Therefore, the treatment plan should be differentiated, and the type of surgery for morbid obesity should be carefully chosen. In most western centers laparoscopic Roux-en-Y gastric bypass (LRYGBP) is the most effective weight loss surgical procedure performed. However, LRYGBP may be associated with higher risk of peri- and postoperative complications in contrast to a purely restrictive procedure to justify this procedure on all patients. Laparoscopic sleeve gastrectomy (LSG) as a staged or non-staged procedure may be an alternative procedure. The aim of this study is to report on the short-term outcomes of LSG, the effect on operative risk reduction.
Methods: A retrospective review of 38 patients who underwent consecutive LSG from November 2007 to November 2008 was performed. LSG was performed through one 5-mm, three 12-mm ports and one 15-mm port, using the Endo-GIA stapler to create a lesser curve gastric tube over a 48-Fr bougie.
Results: Median BMI was 41.60 kg/m2 (33–50). The overall median postoperative excess weight loss (EWL) was 43% at 6 months, 54.50% at 12 months. Of the patients, 39% had resolution of type 2 diabetes mellitus, 48% had resolution of dyslipidemia, 29% in hypertension, 52% in obstructive sleep apnea. In our series we had no complications and the mortality rate was zero.
Conclusion: LSG does minimize postoperative complication rates significantly on high-risk patients and achieves effective short-term weight loss with resolutions in comorbidities. Additional studies are required to evaluate if LSG without the second-stage duodenal switch operation has been an effective weight loss operation. In our experience, LSG was a safe and effective procedure in achieving significant weight loss in obese Iranian patients.
