A Novel Auxiliary Device for Preventing Band Slippage After Laparoscopic Adjustable Gastric Banding: Infra-Band Fixation Using S-Loop.

BACKGROUND

Band slippage is known to be a troublesome complication of laparoscopic adjustable gastric banding (LAGB), often requiring surgical intervention. To prevent band slippage, a new auxiliary device "S-loop" was developed.

METHODS

From July 2010 to January 2014, a total of 814 LAGBs were performed by a single surgeon. The patients were divided into two groups based on the application of S-loop: conventional LAGB group (n = 378) and S-loop group (n = 436). The operative outcomes were compared between the two groups.

RESULTS

The mean operative time and the length of hospital stay were significantly longer in the conventional LAGB group than in the S-loop group (64.3 minutes versus 57.1 minutes; P < .001 and 5.0 hours versus 3.6 hours; P < .001, respectively). The complications occurred in 7.1% of the conventional LAGB group and 1.6% in the S-loop group (P < .001). Slippage was the most common complication: 13 cases were observed in the conventional LAGB group, whereas no slippage was observed in the S-loop group.

CONCLUSION

Infra-band fixation using S-loop is a simple and effective method for preventing band slippage compared with the conventional LAGB.
