Background: Gastric banding is currently one of the most performed procedures for morbid obesity. Results are related in part to the surgical technique and the quality of follow-up. Several bands are currently on the market, and it may bethat the type of band also plays a role in long-term results. The aim of this prospective randomized study was to compare the long-term results of the Lapband and the SAGB.Patients and methods: In three institutions with a common bariatric surgeon, consecutive patients undergoing laparoscopic gastric banding for morbid obesity were randomized to receive either a Lapband or a SAGB. The Lapband was placed using the perigastric and the SAGB with the pars flaccida technique. All data were collected prospectively. The median duration of follow-up was 131 months (103-147). Patients who lost their band were excluded from analysis as of band removal.Results: 180 patients were included between December 1998 and June 2002, 90 in each group. Except for age, which was lower in SAGB patients, the pre-operative characteristics were similar in the two patient groups. Early band-related morbidity was higher in the SAGB group (6,6 vs 0 %, p=0,03). Patients with a Lapband lost weight quicker than those with SAGB (EBMIL 50,8 vs 39,8 after 12 months, p<0,001), but the two weight loss curves joined after 24 months, and no difference could be observed later on up to 12 years after surgery (EBMIL 53,7 vs 58,1 % after 10 years, P=0,68). Long-term complications developed in 91 patients (50,5 %). Severe complications leading to band removal±conversion to another procedure developed in 30 and 40 patients in the Lapband and SAGB group respectively (33,3 vs 44,4 %, p=0,16).Conclusions: This prospective randomized study shows no significant difference in the long-term results of gastric banding between the Lapband and the SAGB. Both bands were associated with significant long-term complication and band removal/conversion rates. Patients who retain their band have acceptable long-term weight loss. It is likely that the concept of gastric banding rather than the device itself plays the most important role in longterm results.
