Is gastro-gastric fixation suture necessary in laparoscopic adjustable gastric banding? A prospective randomized study

BACKGROUND:

The reason for gastro-gastric suture (GGS) in laparoscopic adjustable gastric banding (LAGB) is to prevent migration, slippage, and pouch dilatation. Despite various suturing techniques, these complications are still quite common. In our study, we prospectively randomized patients for GGS and analyzed outcome.

METHODS:

Between September 2006 and February 2008, eighty patients were randomized before LAGB procedure with pars flaccida technique. Forty patients had GGS for band fixation (Group 1), and 40 patients did not (Group 2). Groups were compared for length of surgery (LOS), length of hospital stay (LOHS), early and late complications, and percent of excess weight loss (%EWL). Mann-Whitney U test was used to define statistical differences between groups. P<.05 was accepted as significant.

RESULTS:

Mean body mass index (BMI) of groups 1 and 2 were 43.3±4.9 and 42.2±4.3 kg/m(2), respectively. Mean LOHS was 29.2±9.3 and 25.2±10.5 hours in groups 1 and 2, respectively. There was no statistically significant difference between groups 1 and 2 in comparison of %EWL (P=.344 and P=.132, respectively). There was a significant difference in LOS between groups, and it was shorter in group 2 (P<.05). In terms of complications, slippage rate was higher, migration and port complications were lower in group 2 although not statistically significant (P>.05). Pouch dilatation rate was similar in both groups.

CONCLUSIONS:

LOS is shorter without GGS. There is no difference in rates of slippage, migration, pouch dilatation complications, and %EWL between either approach. In light of our findings, we think that routine use of GGSs should be revisited.
