Transabdominal Preperitoneal Procedure

Area of Science:

• Surgical techniques
• Hernia repair
• Quality improvement in surgery

Background:

• Transperitoneal inguinal herniorrhaphy has evolved through continuous quality improvement.
• Hernia repair techniques aim to minimize recurrence and complications.

Purpose of the Study:

• To identify and elucidate the principles of successful transperitoneal inguinal herniorrhaphy.
• To evaluate the efficacy of different transperitoneal hernia repair methods.

Main Methods:

• A retrospective analysis of 278 patients undergoing 348 hernia repairs between 1989 and 1993.
• Four groups were compared: mesh repair of visualized defect, mesh support of entire inguinofemoral area, staple fixation of mesh (Group I), and staple fixation of mesh (Group II).

Main Results:

• Recurrence rates varied significantly: Group I (23%), Group II (6%), Group III (33%), and Group IV (0%).
• The most common complication was small bowel obstruction due to peritoneal flap dehiscence.
• Adherence to refined principles resulted in 0% recurrence and prompt return to activity over 3 years.

Conclusions:

• Complete dissection and mesh coverage of the entire inguinofemoral area are crucial.
• Staple fixation of mesh prevents displacement, and close reapproximation of peritoneal edges is vital.
• These principles have led to 0% recurrence rates and rapid recovery in recent years.
