Prospective, observational study of intraperitoneal onlay mesh repair with defect closure versus SCOLA for primary ventral hernia

Abstract

Introduction The last decade has witnessed several modifications in the laparoscopic techniques for ventral hernia. The aim of this study was to compare an established repair such as laparoscopic intraperitoneal onlay mesh repair with defect closure (IPOM plus) with subcutaneous onlay endoscopic approach (SCOLA) for medium ventral hernia. Patients and Methods From June 2019 to November 2021, 29 patients undergoing IPOM plus and 22 patients undergoing SCOLA for medium ventral hernia (umbilical and epigastric hernia of size 2–4 cm) were included in the study. A comparative analysis was performed in terms of surgical outcomes and post-operative pain. Results The two groups were comparable in terms of age and body mass index. The mean operation time of the SCOLA group was higher but not statistically significant. The Visual Analogue Scale score for pain after IPOM plus was significantly higher on post-operative day 1, at discharge and on the first follow-up visit. Around 45.4% of patients in the SCOLA group were discharged with the drain in situ which was later removed on the outpatient visit. However, no drains were placed in the IPOM plus group. The rate of seroma formation was 10.34% in the IPOM plus group and 27.27% in the SCOLA group. The material cost of IPOM plus procedure was significantly higher than that of the SCOLA. At the end of 1 year, there was no recurrence in either group. Conclusion Our study showed that the post-operative pain after SCOLA is significantly less compared to IPOM plus. SCOLA is feasible for medium midline ventral hernia. However, a study with larger sample size and longer follow-up is warranted to compare the operative morbidity of the two procedures.
