Summary

Laparoscopic inguinal hernia repair involves a learning curve. Outcomes like complications and recurrences significantly improve after surgeons gain experience with the transabdominal preperitoneal (TAP) technique.

Area of Science:

  • General Surgery
  • Minimally Invasive Surgery

Background:

  • Laparoscopic inguinal hernia repair requires specialized skills not always included in general surgery training.
  • Assessing the learning curve is crucial for surgeons adopting new laparoscopic techniques.

Purpose of the Study:

  • To prospectively audit the initial experience of three surgeons performing laparoscopic inguinal hernia repair.
  • To identify and quantify the learning curve associated with the transabdominal preperitoneal (TAP) mesh repair technique.

Main Methods:

  • 172 consecutive transabdominal preperitoneal (TAP) mesh repairs were performed by three surgeons with limited prior experience.
  • Repairs were divided into two groups: the first 90 (Group 1) and the subsequent 82 (Group 2).
  • Outcomes including hospitalization, conversion rates, complications, recurrences, and return to activity were compared between groups.

Main Results:

  • Group 1 (first 90 repairs) showed higher rates of overnight hospitalization (37% vs. 31%), conversion (2.2% vs. 1.2%), complications (11.7% vs. 0%), recurrence (12.2% vs. 0%), and delayed return to activity (11 vs. 8 weeks).
  • Patient satisfaction was higher in Group 2 (9.0/10) compared to Group 1 (8.2/10).
  • Lack of prior TAP experience correlated with increased conversions, complications, and recurrences.

Conclusions:

  • A surgeon's initial experience with laparoscopic herniorrhaphy demonstrates an identifiable learning curve.
  • Complication and recurrence rates, along with patient satisfaction, improve significantly after the initial learning phase.
  • Prior experience is critical; a complete lack of it increases conversions, complications, and recurrences in laparoscopic inguinal hernia repair.
