Bariatric Surgery Using Different Adjustable Gastric Bands: the Results of Prospective Randomised Study

It has been estimated that LAGB represents about 42% of bariatric operations performed worldwide. There are a number of different adjustable gastric bands available. Few attempts have been made to compare the influence of band design differences for efficiency and complication rate. There are no accepted criteria for choosing this particular operation. In the dissertation we compared one year results after adjustable gastric banding using different adjustable gastric bands – SAGB and MiniMizer Extra. We have determined that laparoscopic adjustable gastric banding is effective and safe bariatric procedure: the average percentage of initial excess body mass index loss was 33,1 ± 21,9%; 34.1% of patients achieved fair, 30,6% - good, 9,4% - very good and 2,4% - excellent results according to BAROS; only 5 (4,9%) major complications were diagnosed. No radical differences were stated between the efficiency and complication rate of the compared adjustable gastric bands: the average percentage of initial excess body mass index loss in SAGB and MiniMizer Extra groups was 28,9 ± 21,3% and 36,8 ± 22.1% respectively, p=0.075; major complication rate was 0 (0%) and 5 (9.3%) respectively, p=0.069. Patients at the age of 40 and older achieved better results using MiniMizer Extra band - the average percentage of initial excess body mass index loss was 37,5 ± 20,8% versus 23,6 ± 13,8% in SAGB group, p=0.002. Patients with initial BMI ≤ 47 achieved better results using MiniMizer Extra band - the average percentage of initial excess body mass index loss was 46,4 ± 20% versus 33,6 ± 24% in SAGB group, p=0,048
