Complex inguinal hernia repairs.

Area of Science:

• General Surgery
• Surgical Innovation
• Hernia Repair Techniques

Background:

• Complex inguinal hernias pose a surgical challenge, often requiring approaches beyond the standard Lichtenstein repair.
• Recurrent or giant hernias necessitate alternative surgical strategies to minimize poor outcomes.
• Preperitoneal approaches, including open (Nyhus, Stoppa) and laparoscopic (TAPP, TEP) methods, are described for complex cases.

Purpose of the Study:

• To evaluate the efficacy and safety of an open preperitoneal approach for managing complex, including giant and recurrent, inguinal hernias.
• To present a standardized technique for open preperitoneal repair in challenging inguinal hernia cases.
• To assess the outcomes, including recurrence and morbidity rates, of this surgical approach.

Main Methods:

• A retrospective analysis of 188 patients undergoing 255 inguinal hernia repairs between November 1993 and December 2007.
• Patients were treated using the Nyhus or Stoppa open preperitoneal approach based on hernia laterality (unilateral/bilateral).
• Progressive preoperative pneumoperitoneum was employed for all patients with oversized inguinal hernias.

Main Results:

• The study involved 121 unilateral and 67 bilateral inguinal hernia repairs.
• Only two instances required orchiectomy; two recurrences were noted among all repairs.
• Zero mortality and acceptable morbidity were reported despite the complexity of the cases.

Conclusions:

• The open preperitoneal approach with mesh prosthesis is a safe and effective treatment for complex inguinal hernias.
• This method achieves very low recurrence and morbidity rates in challenging hernia repairs.
• Progressive preoperative pneumoperitoneum is a key factor for successful intraoperative and postoperative results in giant hernias.
