Background Giant inguinal hernia (GIH) is a rare condition in the developed world, and the literature is scarce. Case reports describe different techniques in an attempt to prevent abdominal compartment syndrome (ACS). We aimed to review our experience with GIH repair. Method A retrospective review of the medical records of all consecutive patients who underwent a tension-free mesh GIH repair using a transverse inguinal incision between 2014 and 2021 at a tertiary university referral center. In brief, the technique included head-down positioning, maximal pre-incision reduction of hernia contents, and repair with mesh. Follow-up was conducted in outpatient clinic. We compared the results to a time-based open standard inguinal hernia repair group (control group). Results During the study period, 58 patients underwent an open GIH repair with mesh without abdominal preparation. 232 patients were included in the control group. The mean surgery duration was 125.5 min in the GIH group and 84 min in the control group (p < 0.001). Bowel resection was not necessary in any case. In-hospital complication rates were 13.8% vs. 5.6% in the GIH and control groups, respectively (p = 0.045). Early complication rates (up to 30 days post-operatively) were 62.1% vs. 14.7% in the GIH and control groups, respectively (p < 0.001). Late complications rate was similar (p = 0.476). ACS and mortality were not reported. No recurrence event was reported in the GIH group. Conclusion Tension-free mesh repair for GIH using a standard transverse inguinal incision is feasible and safe and there is no need for abdominal cavity preparation. Early complications are more common than in the control group, but there were no higher rate of late or severe complications and no recurrence event.
