Totally extraperitoneal (TEP) endoscopic hernia surgery is increasingly popular since it is associated with little postoperative pain and with early return to work. Previous appendectomy may preclude preperitoneal dissection in patients with right-sided hernias. The feasibility of TEP surgery in these patients was the subject of the present study.
Between January 2005 and February 2007 all consecutive patients undergoing TEP surgery were included in a prospective cohort study. The study group consisted of patients with right-sided and bilateral hernias. Operative times, conversions, complication rates, and return to daily activities were recorded. Patients were divided into two groups according to previous appendectomy.
A total of 462 patients with right-sided hernias underwent TEP surgery: 421 patients without previous abdominal surgery (group 1) and 41 patients with previous appendectomy (group 2). The conversion rate was significantly higher in group 2: four patients (10%) were converted to open Lichtenstein repair versus five (1%) in group 1 (p = 0.005). However, we found no significant differences in complication rate, operative time, and return to daily activities.
A right-sided (or bilateral) TEP procedure may be performed safely in patients after previous appendectomy. Despite a higher conversion rate, the vast majority of patients can be operated endoscopically.
完全腹膜外(TEP)内镜疝修补术因术后疼痛轻且能早期恢复工作而越来越受欢迎。既往阑尾切除术可能会妨碍右侧疝患者的腹膜前分离。本研究的主题是TEP手术在这些患者中的可行性。
2005年1月至2007年2月期间,所有连续接受TEP手术的患者均纳入一项前瞻性队列研究。研究组包括右侧和双侧疝患者。记录手术时间、中转率、并发症发生率及恢复日常活动的情况。根据既往阑尾切除术将患者分为两组。
共有462例右侧疝患者接受了TEP手术:421例无腹部手术史的患者(第1组)和41例有阑尾切除术史的患者(第2组)。第2组的中转率显著更高:4例患者(10%)中转至开放的Lichtenstein修补术,而第1组为5例(1%)(p = 0.005)。然而,我们发现并发症发生率、手术时间和恢复日常活动方面无显著差异。
既往阑尾切除术后的患者可以安全地进行右侧(或双侧)TEP手术。尽管中转率较高,但绝大多数患者可以通过内镜进行手术。
