Background
Various types of adjustable gastric bands are used during LAGB, but there is insufficient data comparing different bands in the long term. We carried out a prospective randomized study to compare two different bands.
Methods
Between January 1, 2009 and January 31, 2010, 103 morbidly obese patients were randomized between SAGB and MiniMizer Extra adjustable gastric bands. The SAGB was used in 49 and MiniMizer Extra in 54 patients. Weight loss, comorbidities, long-term complications, and quality of life were evaluated after 5 years.
Results
Patient baseline characteristics were similar in the two groups. The mean patient age was 45.9 ± 11.7 years, and mean preoperative BMI was 47.5 ± 7.3 kg/m2. A total of 90 of 103 patients (87.3 %) completed the 5-year follow-up. The mean excess weight loss was 44.1 and 50.3 % in SAGB and MiniMizer groups, respectively (p = 0.14). A proportion of patients who reached a BMI < 35 kg/m2 was significantly larger in MiniMizer Extra group (52.9 vs 25.5 %; p = 0.01). Complications developed in 15 patients (14.5 %) and consisted of 5 band erosions, 4 port-related complications, 3 band slippages, and 3 band intolerances. All five band erosions developed in MiniMizer Extra group, but the difference was not significant (p = 0.058). No difference was found regarding postoperative complications, resolution of comorbidities, and quality of life between compared groups.
Conclusions
SAGB and MiniMizer Extra bands demonstrated similar long-term results regarding the weight loss, resolution of comorbidities, morbidity, and quality of life.
