A randomized clinical trial comparing early patient-reported pain after open anterior mesh repair versus totally extraperitoneal repair of inguinal hernia

Abstract

Background This was a prospective, multicentre, non-blinded, randomized clinical trial involving two parallel groups of patients. Methods Adult patients with symptomatic unilateral primary inguinal hernia were included in this study. Patients were enrolled and treated in five Finnish hospitals. Eligible patients were randomized by use of a computer-based program to receiving either open anterior repair (modified Lichtenstein) with glue mesh fixation or totally extraperitoneal (TEP) repair. The primary aims were to compare 30-day patient-reported pain scores and return to work after surgery between the two groups. Results A total of 202 patients were randomized: 98 patients to TEP repair and 104 patients to open repair. All randomized patients received their allocated treatment. A total of 86 patients (88 per cent) in the TEP group and 94 patients (90 per cent) in the Lichtenstein group completed the 30-day follow-up. Patients experienced less early pain (P < 0.001) and used less analgesics after TEP repair, compared to those who had modified Lichtenstein repair. Two patients in the TEP group and five in the Lichtenstein group developed superficial wound infection (P = 0⋅446). Only one reoperation was performed in the Lichtenstein group due to haematoma. Conclusion TEP inguinal hernia repair is associated with less early postoperative pain compared to the open glue mesh fixation technique. Trial registration NCT03566433 (http://www.clinicaltrials.gov).

A Narrative Review on Polypropylene Mesh Complications in Inguinal Hernia Repair - is Titanized Mesh an Option?

“…TAPP was associated with a lower seroma rate, and TEP was associated with a lower edema rate according to a meta-analysis [37]. There was less early pain and fewer analgesics after TEP repair, compared to Lichtenstein repair with similar infection rates in this Randomized Controlled Trial (RCT) [38].…”

Laparoscopic vs. Open Approach in Emergent Inguinal Hernia: Our Experience and Review of Literature

“…Different techniques and approaches for inguinal hernia repair have been introduced parallel to surgery development in recent decades. In this context, the introduction of minimally invasive approaches in elective inguinal hernia repair has already demonstrated many advantages: a faster return to daily activities, less postoperative pain and analgesic consumption, and lower rate of wound infection when comparing to open approaches [6][7][8][9]. Nevertheless, the application of laparoscopic approaches to emergent repairs is still under discussion [4,9,10].…”
