Comparison of Post-Operative Pain and Hospital Stay in Patients Undergoing Intraperitoneal Onlay Mesh (IPOM) with open Sublay Mesh Repair Hernioplasty

Abstract

Objective: To compare the outcome (in-terms of mean post-operative pain and hospital stay) of intraperitoneal onlay mesh (IPOM) with open sublay mesh repair in patients undergoing ventral hernia repair. Materials and Methods: A total number of 150 patients of ventral hernia planned for hernia repair were included in this randomized controlled trial from Jan-2020 to June-2021. Patients were divided into Group I (IPOM) and group II (OSM). IPOM; in these patients intraperitoneal onlay mesh (IPOM) repair was done laparoscopically. OSM group; in these patients open mesh repair was done. Post-operative pain score and hospital stay were main study outcomes. Results: Mean duration of herniation was 5.96±3.24 months in IPOM and 6.28±2.35 months in OSM group (p-value 0.49). Hypertension was the commonest morbidity was hypertension, diagnosed in 40 (53.3%) patients in IPOM and in 41 (54.7%) patients in OSM group (p-value 0.88). Mean post-op pain was significantly high in OSM group; 2.60±1.06 versus 1.68±1.06 in OSM group (p-value <0.0001). Mean hospital stay was shorter in IPOM group; 4.44±1.62 days versus 5.65±1.98 days in OSM group (p-value <0.0001). Conclusion: IPOM repair is a viable and safe option, according to the results of our research. The open SUBLAY approach has a higher morbidity than IPOM laparoscopic ventral hernia repair. A shorter hospital stay is another benefit of the IPOM. Keywords: undergoing intraperitoneal onlay mesh (IPOM), open sublay mesh repair hernioplasty, post-operative pain.
