Objective：To investigate the 5 year efficacy of laparoscopic sleeve gastrectomy for the treatment of morbid obesity.
Methods：The clinical data of 31 patients with severe morbid obesity and related complications who were admitted to the Shengjing Hospital of Chinese Medical University from January 2006 to December 2007 were retrospectively analyzed. The 31 patients received laparoscopic sleeve gastrectomy and were followed up for 5 years to observe the perioperative condition, incidence of long term complications, application of hypoglycemic drug and insulin before and after operation, the body mass index (BMI) was detected 6 months, 1, 2, 3, 4, 5 years after operation, and the decrease of excess weight loss (EWL) was analyzed. The remission rate of complications, incidence of complications and the patient satisfaction score were recorded. The count data were analyzed using the chi square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated measure ANOVA, a Greenhouse Geisser adjustment was used to correct serial dependency.
Results：Twenty five patients were followed up for 5 years postoperatively. Of the 25 patients, 4 (16.0%) had gastroesophageal reflux disease, and were cured by medical treatment; 1 patient (4%) had anastomotic stenosis; the percentage of EWL of 2 patients (8.0%) was under 60%; 4 patients (16.0%) had occasional obdominal pain. The percentage of patients with diabetes mellitus was decreased from preoperative 9.7%(3/31) to postoperative 4.0%(1/25), with a significant difference ( P <0.05). The percentage of patients with fatty liver was decreased from preoperative 93.5% (29/31) to postoperative 32.0%(8/25), with significant difference ( χ 2 =35.51, P <0.05). The level of BMI was decreased from preoperative (38.8±4.2)kg/m 2 to postoperative (28.5±3.1)kg/m 2, with significant difference ( F=113.36, P <0.05). The percentage of EWL was increased from preoperative 42% ±16%, with significant difference ( F=41.71, P <0.05). There was no significant difference in the patient satisfaction score between each year within the 5 years ( F=0.92, P >0.05).
Conclusions：Laparoscopic sleeve gastrectomy is effective in losing weight with few long term complications.
