Faster Recovery and Reduced Pain With Minimally Invasive Inguinal Hernia Repair: A Prospective Comparative Analysis

Inguinal hernia repair is one of the most common surgical procedures worldwide, with open (Lichtenstein) and minimally invasive (laparoscopic/robotic) techniques being widely used. This study aimed to compare postoperative outcomes between open and minimally invasive inguinal hernia repair, focusing on complications, chronic pain, recovery and quality of life.

This prospective observational study included 50 male patients undergoing elective inguinal hernia repair at a tertiary care centre in India. Patients were divided into two groups: Group A (n = 25, open Lichtenstein repair) and Group B (n = 25, minimally invasive TEP/TAPP or robotic-assisted TAPP). Data on demographics, comorbidities, surgical techniques, postoperative complications, pain, recovery time and patient satisfaction were collected and analysed. Statistical analysis was performed using SPSS version 17.0, with p < 0.05 considered significant.

Group A patients were older (mean age 66.12 vs. 58.84 years) and had more comorbidities (58% vs. 42%). Minimally invasive repair demonstrated superior outcomes, with 36% of Group B patients discharged within 1 day (vs. 20% in Group A) and lower chronic pain rates (16% vs. 40%). Group B also showed faster return to daily activities (68% within 2 days vs. 12%). However, Group B had a slightly higher need for pain medication and one recurrence due to mesh infection. Both techniques had high patient satisfaction, though open repair remained preferred for high-risk patients (24% ASA III in Group A vs. 0% in Group B).

Minimally invasive inguinal hernia repair offers faster recovery and reduced chronic pain compared with open techniques, making it favourable for healthier patients. However, open repair remains relevant for elderly and high-risk individuals.
