Abstract

PURPOSE
Laparoscopic total extraperitoneal (TEP) repair of inguinal hernia is technically challenging enough to build high barrier to entry. The purpose of this study was to identify clinical factors influencing technical difficulty with laparoscopic TEP according to learning period.
METHODS
We conducted a retrospective study of 112 adult patients who underwent laparoscopic TEP for unilateral inguinal hernia from January 2009 to September 2013. A technically difficult case was defined as the 70th percentiles or more in the distribution curve of operative time, major complication, or open conversion.
RESULTS
The rate of body mass index (BMI) above 25 kg/m2 was significantly higher in the difficult group than the nondifficult group in the learning period of laparoscopic TEP (57.9% vs. 26.8%, respectively, P = 0.020). However, in the experience period, it revealed no statistical difference with technical difficulty (31.3% vs. 33.3%, respectively, P = 0.882). In multivariate analysis, BMI (> or =25 kg/m2) was identified as a significant independent factor for technical difficulty with laparoscopic TEP in the learning period (odds ratio, 4.572; P = 0.015).
CONCLUSION
Patient's BMI (> or =25 kg/m2) can create technical difficulty with laparoscopic TEP only in the learning period, but not in the experience period. Therefore BMI could be applied as one of the guidelines for patient selection, especially for surgeons in the learning curve of laparoscopic TEP.
