Brief summary

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.

Detailed description

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.

Secondary

MeasureTime frameDescription
Number of Complications3 monthsDetermined by medical examinations: Whether there is seroma, haematoma or ecchymosis at 1st- and 3rd-month controls (in terms of number)
Postoperative pain1 weekPostoperative 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)
postoperative recovery1 dayPostoperative 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)
