A newer method of seroma reduction by fenestration of pseudo-sac during laparoscopic repair of direct inguinal hernia: A randomised, controlled pilot study
Abstract
Background: Minimally invasive surgeries for inguinal hernia repair have been reduced post-operative morbidity. However, certain complications such as seroma formation are unavoidable. In this study, we introduce a newer technique of reducing seroma formation by fenestration of the pseudo-sac (thickened transversalis fascia) in patients undergoing laparoscopic hernia repair for uncomplicated direct inguinal hernia. Patients and Methods: A randomised, controlled pilot study was conducted from January 2019 to December 2020 for the patients undergoing laparoscopic hernia repair for uncomplicated direct inguinal hernia. Study participants were randomised into interventional group and control groups. Demographics, operative duration and complications including post-operative pain and seroma on days 1, 10 and 30 were analysed between both the groups. Results: A total of 20 cases with 30 hernias were included in the study. Demographic data were comparable between the two groups. The intervention group showed a statistically significant decrease in the incidence of seroma formation on the post-operative day 10 (13.3% vs. 46.6%, P = 0.046). The mean volume of seroma on day 10 was also less compared to the non-fenestration group (2.5 vs. 6.58 ml, P = 0.048). After the 30th day, no patient had a presence of seroma. There were no statistically significant differences in terms of mean operative duration, post-operative pain and other complications. Conclusion: Fenestration of pseudo-sac in laparoscopic hernia repair for uncomplicated direct inguinal hernia is a simple and effective technique. It has reduced the incidence and volume of seroma formation without any increased risk of infection, acute or chronic pain and recurrence.
