Laparoscopic Intraperitoneal Onlay Mesh Repair for Non-Midline Incisional Hernias: A Single-Center Clinical Study

Area of Science:

• Abdominal wall surgery
• Minimally invasive surgery
• Hernia repair

Background:

• Non-midline incisional hernias present surgical challenges.
• Limited evidence exists for laparoscopic intraperitoneal onlay mesh (IPOM) in this context.

Purpose of the Study:

• Evaluate the safety and efficacy of laparoscopic IPOM for non-midline incisional hernias.
• Assess the impact of different defect closure techniques on perioperative outcomes.

Main Methods:

• Single-center retrospective study of 43 patients undergoing laparoscopic IPOM for non-midline incisional hernias.
• Data collected included demographics, hernia characteristics, closure techniques, operative details, complications, and recurrence.
• Kruskal-Wallis test used for comparisons among closure groups.

Main Results:

• Mean defect area was 57.15 cm², operative time 133.51 minutes, blood loss 20.65 mL, and hospital stay 5.79 days.
• Overall complication rate was 7.0% (chronic pain, seroma, ileus); 1 recurrence occurred.
• Combined closure technique associated with larger defects and longer operative times, but comparable early outcomes.

Conclusions:

• Laparoscopic IPOM demonstrates safety and efficacy for non-midline incisional hernias with low complication and recurrence rates.
• Combined closure technique is effective for larger defects, managing operative time without adverse early perioperative effects.
