Five-year results of laparoscopic sleeve gastrectomy.

Background: Laparoscopic sleeve gastrectomy (LSG) is gaining popularity, but studies reporting long-term results are still rare. The objective of this study was to present the 5-year outcome concerning weight loss, modification of co-morbidities, and late complications.

Methods: This is a retrospective analysis of a prospective cohort with a minimal follow-up of 5 years. A total of 68 patients underwent LSG either as primary bariatric procedure (n = 41) or as redo operation after failed laparoscopic gastric banding (n = 27) between August 2004 and December 2007. At the time of LSG, the mean body mass index (BMI) was 43.0 ± 8.0 kg/m(2), the mean age 43.1 ± 10.1 years, and 78% were female. The follow-up rate was 100% at 1 year postoperatively, 97% after 2 years, and 91% after 5 years; the mean follow-up time was 5.9 ± 0.8 years.

Results: The average excessive BMI loss was 61.5% ± 23.4% after 1 year, 61.1% ± 23.4% after 2 years, and 57.4% ± 24.7% after 5 years. Co-morbidities improved considerably; a remission of type 2 diabetes could be reached at 85%. The following complications were observed: 1 leak (1.5%), 2 incisional hernias (2.9%), and new-onset gastroesophageal reflux in 11 patients (16.2%). Reoperation due to insufficient weight loss was necessary in 8 patients (11.8%).

Conclusions: LSG was effective 5.9 years postoperatively with an excessive BMI loss of almost 60% and a considerable improvement or even remission of co-morbidities.
