The Impact of High Surgical Volume on Outcomes From Laparoscopic (Totally Extra Peritoneal) Inguinal Hernia Repair.

Abstract

Laparoscopic hernia repair is characterised by a steep learning curve for the surgeon, and proficiency and outcomes are dependent on experience. The aim of this study was to compare laparoscopic totally extra peritoneal (TEP) inguinal hernia repair outcomes conducted by a single surgeon as experience changed over time. Clinical records of 100 consecutive patients who underwent laparoscopic TEP inguinal hernia repair (n=113 hernias) at Kent and Canterbury Hospital by a single laparoscopic surgeon over a four-year period were reviewed for postoperative outcomes. Outcomes were compared with a previous cohort of patients undergoing TEP repair in the preceding three years. One patient experienced chronic postoperative pain, but there were no recurrences, wound infections, haematomas, or conversions compared to three recurrences, three conversions to open operations, one haematoma, and one episode of postoperative pain in the preceding period. Laparoscopic TEP inguinal hernia repair can be further improved with surgical proficiency and high surgical volumes.
