Background
Band slippage is a significant complication of laparoscopic adjustable gastric band (LAGB) surgery for the treatment of morbid obesity. This involves prolapse of part of the stomach, with varying degrees of gastric obstruction. The original perigastric technique (PGT) was associated with slippage rates of up to 25%. The pars flaccida technique (PFT) is the more commonly used technique today, reducing slippage rates to as low as 1.4%. We report a technique not previously described, the modified PFT with the use of mesh, and compare slippage rates between these three techniques for band placement.
Methods
A prospectively entered, retrospective review of 1,446 consecutive patients undergoing LAGB by a single surgeon was undertaken. Patients were divided into five consecutive groups: PGT learning curve (PGTLC) (n = 68), PGT (n = 19), mesh PFT (MPFT) (n = 415), mesh plication PFT (MPPFT) (n = 131), and MPPFT with inadequate follow-up (n = 813). Patient characteristics, band slippage, and other complication rates were compared between groups.
Results
The slippage rates for each group were: PGTLC (10%), PGT (5%), MPFT (0.8%), and MPPFT (0%). This demonstrated a statistically significant difference between the slippage rates for each group (p < 0.001). Combining the MPFT and MPPFT groups, there was a statistically significant difference in band slippage compared to the PGT group (p < 0.001).
Conclusion
While the MPFT is associated with low band slippage rates, the MPPFT results in further reductions in band slippage. The routine use of this modification to the MPFT is safe and may reduce operative morbidity. A randomized comparison of these techniques is warranted.
