title: Long-term follow-up after laparoscopic sleeve gastrectomy: 8-9-year results.
abstract: BACKGROUND
  Laparoscopic sleeve gastrectomy (LSG) has rapidly gained popularity as a definitive bariatric procedure despite the sparse long-term follow-up data. On the basis of extensive experience with the open Magenstrasse and Mill operation, we began practice of LSG in 2000. The objective of the present study was to analyze 8-9 years of our follow-up data for LSG at a university hospital in the United Kingdom.
  
  
  METHODS
  From January 2000 to December 2001, 20 patients underwent LSG. A 32F bougie was used for calibration in all cases.
  
  
  RESULTS
  The preoperative median body mass index was 45.8 kg/m(2) (range 35.8-63.7), and 9 patients (45%) were superobese (body mass index ≥ 50 kg/m(2)). For LSG as a definitive bariatric procedure, 8-9-year follow-up data were available for 13 patients. Of the remainder, 4 patients underwent revision surgery and 3 were lost to follow-up after 2 years. For the entire cohort, the median excess weight loss (EWL) was 73% (range 13-105%) at 1 year, 78% (range 22-98%) at 2 years, 73% (range 28-90%) at 3 years, and 68% (range 18-85%) at 8 or 9 years (P = .074). Of the 13 LSG-only patients with 8-9 years of follow-up, 11 (55% of the starting cohort) had >50% EWL at 8 or 9 years. No significant difference was found in the initial body mass index between the LSG-only patients with >50% EWL and others (45.9 kg/m(2), range 35.8-59.4 versus 45.7 kg/m(2), range 38.9-63.7, respectively; P = .70). The LSG-only patients with >50% EWL had a marginally significantly greater EWL at 1 year compared with the others (76%, range 48-103% versus 45%, range 13-99%, respectively; P = .058).
  
  
  CONCLUSIONS
  At 8-9 years of follow-up, 55% of patients had >50% EWL from LSG as a definitive bariatric procedure.
