Midline Extraperitoneal Approach for Obturator Hernia Repair

Area of Science:

• Surgical Innovation
• Hernia Repair
• Gastrointestinal Surgery

Background:

• Obturator hernia (OH) is a rare cause of bowel obstruction, predominantly affecting elderly women.
• Current surgical approaches for OH lack a definitive consensus.
• The midline extraperitoneal approach is evaluated for OH treatment.

Purpose of the Study:

• To assess the efficiency and safety of the midline extraperitoneal approach for obturator hernia repair.
• To evaluate the outcomes in elderly female patients undergoing this surgical technique.

Main Methods:

• Retrospective analysis of six elderly female patients with OH.
• Surgical repair using the midline extraperitoneal approach.
• Evaluation of patient characteristics, intraoperative findings, and postoperative course.

Main Results:

• All patients were elderly women (median age 90 years) with OH.
• Two patients required bowel resection due to ischemia; none experienced recurrence or infection.
• The approach facilitated diagnosis, repair of coexisting hernias, and bowel resection when necessary.

Conclusions:

• The midline extraperitoneal approach is an efficient and safe method for OH repair.
• This technique improves visualization, reduces risks to obturator vessels, and allows simultaneous repair of other pelvic hernias.
• It is particularly beneficial in elderly patients, potentially lowering mesh infection risk during bowel resection.
