Laparoscopic repair vs open surgery for incisional hernias: a comparison study

Area of Science:

• Abdominal Surgery
• Minimally Invasive Surgery
• Surgical Innovation

Background:

• Incisional hernias occur in 2-11% of laparotomies, with primary closure recurrence rates of 20-46%.
• Despite advancements, a definitive gold standard for incisional hernia repair remains undefined.
• Laparoscopic repair is a promising technique, though limited data exists.

Purpose of the Study:

• To compare the outcomes of laparoscopic repair (LR) versus open prosthetic repair (OR) for incisional hernias.
• To evaluate key metrics including operative time, complications, hospital stay, and recurrence rates.

Main Methods:

• A comparative study of 11 patients undergoing LR and 15 patients undergoing OR.
• Data collected included patient demographics, hernia characteristics, operative details, and postoperative outcomes.
• Prosthetics used were e-PTFE for LR and e-PTFE or Polypropylene for OR; peripheral hernias were excluded.

Main Results:

• Laparoscopic repair (LR) had longer operative times but shorter hospital stays compared to open repair (OR).
• No intraoperative complications occurred in LR, versus one in OR. LR group had fewer early and late complications.
• Follow-up showed no recurrences in either group (mean 18 months for LR, 40 months for OR).

Conclusions:

• Laparoscopic repair of incisional hernias is as effective as open prosthetic repair.
• The minimally invasive approach offers advantages such as reduced prosthesis manipulation and fewer infectious complications.
• LR presents a safe and effective alternative for incisional hernia treatment.
