Intraperitoneal onlay mesh versus laparoscopy-assisted ventral hernia patch mesh repair in small primary ventral hernias: A randomised control trial

Abstract

Aims: The aim of this study is to compare and evaluate short-term outcomes of laparoscopy-assisted composite patch mesh repair versus laparoscopic intraperitoneal onlay mesh in small primary midline ventral hernias. Materials and Methods: Eighty consecutive patients with small (<2 cm) midline ventral hernia admitted to the Department of General and Laparoscopic surgery at Sir Ganga Ram Hospital, New Delhi, from January 2017 to May 2019 were included in the study and randomised into two groups. Group A included patients who underwent laparoscopic intraperitoneal onlay mesh repair with the classical barrier flat mesh and Group B patients underwent laparoscopy-assisted ventral hernia patch-mesh repair. Parameters assessed at the follow-up were early post-operative pain by Visual Analogue Scale score, wound complications, early recurrence and hospital stay. Results: Early post-operative pain was more in the laparoscopic intraperitoneal onlay mesh group and the difference was statistically significant. Usage of additional analgesia in the post-operative period was required only in the laparoscopic intraperitoneal onlay mesh group. There was a statistically significant difference between the two groups in terms of hospital stay. Conclusion: For primary midline ventral hernia, with defect size <2 cm, laparoscopy-assisted composite patch mesh repair is feasible and safe. It causes less pain and necessitates less usage of additional analgesia enabling patients to be discharged earlier.
