Open preperitoneal versus anterior approach for recurrent inguinal hernia: a randomized study.

Area of Science:

• General Surgery
• Surgical Oncology

Background:

• Inguinal herniorrhaphy is a common procedure, with 15% of cases involving recurrence.
• Repairing recurrent inguinal hernias is challenging due to tissue distortion and anatomical changes.

Purpose of the Study:

• To compare posterior preperitoneal versus anterior tension-free approaches for unilateral recurrent inguinal hernia repair.
• To evaluate complications and early recurrence rates between the two surgical methods.

Main Methods:

• A randomized study involving 120 patients divided into two groups: posterior preperitoneal approach (Group A) and anterior tension-free repair (Group B).
• Primary endpoint: recurrence. Secondary endpoints: time off work, postoperative pain, scrotal swelling, and wound infections.

Main Results:

• Group A showed significantly shorter mean hospital stays (1.2 days) and return-to-work times (8.2 days) compared to Group B (4.7 and 11.2 days, respectively).
• Recurrence rates were 3.3% in Group A and 6.25% in Group B.
• Group B experienced higher postoperative pain scores and overall complication rates.

Conclusions:

• The open preperitoneal repair demonstrates a low recurrence rate and effectively covers defects with a single mesh.
• This approach is significantly superior to the anterior method for recurrent inguinal hernia repair.
