Comparison of TEP and eTEP Methods in Inguinal Hernia Repair

The enhanced-view totally extraperitoneal (eTEP) technique provides a wider operative field than the conventional totally extraperitoneal (TEP) technique and may facilitate dissection, instrument manipulation, and mesh placement. This study evaluates the potential advantages of eTEP compared with TEP in laparoscopic inguinal hernia repair.

About this study

The aim of this study was to compare the laparoscopic totally extraperitoneal (TEP) and enhanced-view totally extraperitoneal (eTEP) techniques for inguinal hernia repair. The two techniques were compared in terms of perioperative parameters, postoperative complications, early recurrence, length of hospital stay, postoperative pain, and quality of postoperative recovery. Quality of recovery was assessed using the Turkish version of the 15-item Quality of Recovery questionnaire (QoR-15T), and the outcomes were statistically compared between the TEP and eTEP groups.

  2. Postoperative pain

    Time frame: 1 week

    Postoperative pain was assessed using the Visual Analogue Scale (VAS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst possible pain. VAS scores were assessed on postoperative day 1 and at postoperative week 1. (in terms of number)

  3. postoperative recovery

    Time frame: 1 day

    Postoperative recovery was assessed using the 15-item Quality of Recovery questionnaire (QoR-15), with a total score ranging from 0 to 150. Higher scores indicate better postoperative recovery, whereas lower scores indicate poorer recovery. The QoR-15 score was assessed at 24 hours postoperatively. (in terms of number)
