Prospective, double center, 1-year results of adjustable gastric banding with MIDBAND (gastro-gastric suture . non-gastro-gastric suture).

PURPOSE

Although laparoscopic adjustable gastric banding (LAGB) is a popular bariatric procedure, few comprehensive studies have been investigated on the use of non-gastro-gastric sutures (NGGSs) for decreasing postoperative complications. This study aimed to assess and compare the safety and effectiveness of MIDBAND with or without gastro-gastric sutures (GGSs).

METHODS

Between February 2013 and March 2014, 41 severely obese patients underwent primary LAGB using pars flaccid technique at double center in South Korea. Excess weight loss, operative time and postoperative complications were assessed and compared between a GGS group (group 1) and a NGGS group (group 2), and patients were followed monthly for 1 year.

RESULTS

Mean body mass indices in groups 1 and 2 were 38.4 ± 4.7 and 38.9 ± 5.0 kg/m, respectively, and mean percentage excess weight losses (%EWLs) were 59.9% ± 28.4% and 50.9% ± 20.0%, respectively, at 6 months, and 75.8% ± 26.6% and 72.5% ± 27.5%, respectively, at 12 months, and these intergroup differences of %EWL were not significant (P = 0.256 and P = 0.704, respectively). Mean operative time (57.2 minutes) was shorter in group 2 than in group 1 (79.2 minutes) (P < 0.001). In terms of complications, pouch dilatation rates were similar in the 2 groups, and no case of gastric band erosion was encountered.

CONCLUSION

Operative time was shorter in the NGGS group, and pouch dilatation rates and %EWL were similar in the 2 groups. We conclude NGGS using MIDBAND is both straightforward and effective. A long-term prospective comparative study is needed to demonstrate the safety and efficacy of NGGS.
