Improved outcomes for lap-banding using the Insuflow device compared with heated-only gas

Abstract

Background and objectives: Preconditioning gas by humidification and warming the pneumoperitoneum improves laparoscopic outcomes. This prevents peritoneal desiccation and detrimental events related to traditional cold-dry gas. Few comparisons have been done comparing traditional cold-dry, heated-only, and humidified-warmed carbon dioxide.

Methods: A prospective, controlled, randomized, double-blind study of laparoscopic gastric banding included 113 patients and compared traditional dry-cold (n=35) versus dry-heated (n=40), versus humidified-warm gas (n=38). Pain medications were standardized for all groups. Endpoints were recovery room length of stay, pain location, pain intensity, and total pain medications used postoperatively for up to 10 days.

Results: The humidified-warmed group had statistically significant differences from the other 2 groups with improvement in all end points. The dry-heated group had significantly more pain medication use and increased shoulder and chest pain than the other 2 groups had.

Conclusion: Using warm-humidified gas for laparoscopic gastric banding reduces shoulder pain, shortens recovery room length of stay, and decreases pain medication requirements for up to 10 days postoperatively. Dry-heated gas may cause additional complications as is indicated by the increase in pain medication use and pain intensity.
