Anatomical peculiarities of dissection in the transabdominal preperitoneal procedure for inguinal hernias.

Abstract

Inguinal hernia, a common surgical pathology, has substantial medical, social, and economic implications. Over time, various repair techniques have been explored to optimize outcomes, considering multiple postoperative factors beyond recurrence risk. This article aims to define anatomical and technical aspects impacting the immediate and late postoperative evolution of patients with inguinal hernia. Precise knowledge of anatomical structures and standardized surgical gestures result in the reduction of intraoperative and postoperative complications. Throughout history, the alloplastic procedure has demonstrated superiority over the anatomical approach, reinforcing the potential for ongoing advancements. Correct performance according to well-defined principles improves patients' quality of life after inguinal hernia surgery. These principles encompass the exact knowledge of anatomy, dissection steps, dissection limits, the sequence of dissection, and the prosthetic materials used. We describe our approach, with the laparoscopic method representing over 90% of cases at our clinic, indicating the shift towards minimally invasive techniques and emphasizing adherence to rigorous principles to achieve low perioperative complications.
