Abstract

Background

Laparoscopic sleeve gastrectomy (LSG) has been validated as a safe and effective treatment for morbid obesity. However, data of the long-term outcome remains lacking.

Methods

A total of 1759 LSG was performed as primary bariatric procedure from 2005 to 2017 with mean age of 35.2 ± 10.3 years old (14–71), female 69.7%, mean body mass index (BMI) 37.9 ± 7.7 kg/m2, and mean waist width 113.7 ± 17.9 cm. All patients were evaluated and managed under a strict multidisciplinary team approach. A retrospective analysis of a prospective bariatric database and telephone interview of patients who defaulted clinic follow-up at 10 years was conducted.

Results

The mean operating time, intraoperative blood, and hospital stay of LSG were 121.5 ± 36.5 min, 40.8 ± 69.7 ml, and 2.8 ± 2.7 days, respectively. The 30-day postoperative major complication occurred in 25 (1.4%) patients. The major complication rate was 15% at first year and 0% at the last year. The follow-up rate at 1, 5 and 10 years were 89.3%, 52.1 and 64.4%. At postoperative 1, 5, and 10 years, the mean percentage of total weight loss (%TWL) and excess weight loss (EWL%) of LSG patients were 33.4, 28.3, and 26.6% and 92.2, 80.1, and 70.5%, respectively. The mean BMI became 27, 26.2, and 27.1 kg/m2 at postoperative 1, 5, and 10 years. At follow-up, a total 69 patients needed surgical revision due to reflux disease (n = 45), weight regain (n = 19), persistent diabetes (n = 2), and chronic fistula (n = 3). The type of revision procedures were hiatal repair and gastropexy (n = 29), Roux-en Y gastric bypass (RYGB) (n = 23), and single anastomosis bypass (n = 17) with median time to revision 33 months (range 3–62). At 10 years, the overall revision rate was 21.5% (14/65) and 11(16.9%) of 65 patients were converted to RYGB. The other 54 patients remained at LSG anatomy, but 45% of them required proton pump inhibitor for reflux symptoms.

Conclusions

Our results showed that primary LSG is a durable primary bariatric procedure with sustained weight loss and a high resolution of comorbidities at 10 years, but about half the patients had de novo GERD. The need for conversion to RYGB was 16.9% at 10 years.
