Background The total extraperitoneal (TEP) technique is known for its complexity compared to the transabdominal preperitoneal technique (TAPP). This study aimed to streamline the TEP procedure by introducing the 3-2-1 method, which involves creating three surgical planes, implementing two transitions, and establishing a spacious preperitoneal space. The objective was to comprehensively evaluate the safety, efficacy, and reliability of this approach.
Methods A total of 358 patients with 380 inguinal hernias underwent TEP repair using the 3-2-1 method via the retromuscular approach. Patient characteristics, operative time, hospital stay, complications, and recurrence rates were assessed.
Results Among the hernias, 190 were on the right side, 140 on the left side, and 50 were bilateral. The distribution of hernia types included indirect hernia (201), direct hernia (132), compound hernia (16), complex hernia (6), and femoral hernia (3). The average operative time was 58 minutes for unilateral hernias and 110 minutes for bilateral hernias. Postoperative complications occurred in 32 cases (8.9%), but no serious complications were observed. The average hospital stay was 7 days, and patients were followed up for an average of 49 months. There were no cases of chronic pain or recurrence.
Conclusions The 3-2-1 method for laparoscopic TEP repair of inguinal hernias proves to be a simple, safe, effective, and reliable approach.
