Laparoscopic mesh removal for otherwise intractable inguinal pain following endoscopic hernia repair is feasible, safe and may be effective in selected patients

Background Laparoscopic inguinal hernia repair is preferred over an open technique because of reduced recovery time, favorable cost effectiveness, and less chronic postoperative inguinal pain. Nevertheless, some patients develop a nociceptive inguinal pain syndrome possibly related to the presence of the mesh. This is the first study describing feasibility, safety, and effectiveness of laparoscopic mesh removal in patients with chronic pain after endoscopic hernia repair. Methods Pre- and intraoperative data of chronic pain patients scheduled for endoscopic mesh removal were prospectively collected by a standard evaluation form. Long-term efficacy was determined using pain scores, patient satisfaction, and quality of life questionnaire. A Wilcoxon signed-rank test was used to determine significant differences between pre- and postoperative pain scores. Results Fourteen patients were studied (11 males, median 52 years). Median operating time was 103 min. Conversion to open surgery was not required. One intraoperatively recognized bladder laceration was laparoscopically closed. Otherwise, no intraoperative or postoperative complications occurred. Eight months postoperatively (median), pain scores had dropped from eight to four ( p
