Causes of recurrence after laparoscopic hernioplasty. A multicenter study
Surgical Endoscopy
|April 16, 1998
Summary
Recurrence after laparoscopic hernioplasty is rare (0.4%) in experienced hands. Factors like mesh fixation and size, and missed hernias, contribute to recurrence, with experience reducing some of these issues.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Hernia Repair
Background:
- Recurrence after laparoscopic hernioplasty can occur due to factors beyond surgical learning curves.
- Investigating common causes of failure in laparoscopic hernia repair is crucial for improving outcomes.
Purpose of the Study:
- To identify common factors contributing to recurrence after laparoscopic hernioplasty.
- To analyze failure mechanisms in a large, multicenter cohort of laparoscopic hernia repairs.
Main Methods:
- Retrospective review of 10,053 laparoscopic hernioplasties (Transabdominal Preperitoneal - TAPP, or Totally Extraperitoneal - TEP) performed between 1990 and 1996.
- Analysis of recurrence causes in patients followed for at least 6 months, with a median follow-up of 36 months.
Main Results:
- A low recurrence rate of 0.4% (35 out of 10,053 repairs) was observed in patients with adequate follow-up.
- Identified causes of recurrence included inadequate mesh fixation (lateral and medial), mesh size issues, missed lipomas, missed hernias, and mesh defects.
- Recurrence rates related to missed hernias and small mesh size decreased with surgeon experience.
Conclusions:
- Laparoscopic hernioplasty by experienced surgeons yields extremely low recurrence rates.
- Some recurrence causes are mitigated by surgical experience, while others necessitate technical or equipment modifications.
