Incisional hernia after open versus laparoscopic sigmoid resection.

Area of Science:

• Colorectal Surgery
• Minimally Invasive Surgery
• Surgical Complications

Background:

• Incisional hernias are common after open surgery, with up to 20% incidence over 10 years.
• Long-term hernia risk data after laparoscopic colonic surgery is limited.
• This study aimed to compare long-term hernia incidence after laparoscopic versus open sigmoid resection.

Purpose of the Study:

• To evaluate and compare the long-term incidence of incisional hernias following laparoscopic sigmoid resection versus open sigmoid resection.
• To provide data on the comparative safety and efficacy of these surgical approaches regarding hernia development.

Main Methods:

• Prospective matching of patients undergoing laparoscopic sigmoid resection (1995-2004) with a consecutive open surgery cohort.
• Telephone questionnaires followed by clinical examination for suspected hernias.
• Data collection on primary operation factors, hernia status, and general risk factors.

Main Results:

• A total of 201 patients completed the study (58 laparoscopic, 143 open).
• Median follow-up was 4.6 years for laparoscopy and 4.9 years for open surgery.
• Incisional hernia incidence was 3.4% in the laparoscopic group versus 14.7% in the open surgery group (P=0.026).

Conclusions:

• Laparoscopic sigmoid resection is associated with a significantly lower incidence of incisional hernias compared to open surgery.
• Minimally invasive sigmoid resection offers a potential advantage in reducing long-term hernia complications.
