Comparison of Laparoscopic Intraperitoneal Onlay Mesh (IPOM) Hernioplasty With Laparoscopic IPOM-Plus: Our Initial Experience in Pakistan

Objectives Laparoscopic intraperitoneal onlay mesh hernioplasty (IPOM) for ventral hernias has been used for a long time. However, there have been some issues associated with it, thereby leading to the introduction of a new technique that involves laparoscopic closure of the fascial defect with suture followed by intraperitoneal onlay mesh placement (IPOM-Plus). We carried out this study to compare the outcome of laparoscopic IPOM with fascial defect closure versus without defect closure in midline ventral hernia repair in terms of recurrence. Methodology This comparative study was carried out in the Department of Surgery, Services Hospital, Lahore, from October 16, 2020, to April 15, 2022. A total of 84 patients of both genders, aged between 18 and 70 years, presenting with midline ventral hernia were included in the study. Patients with recurrent hernia, unstable cardiopulmonary conditions, neurological or psychiatric diseases, chronic renal disease, congestive cardiac failure, and chronic obstructive pulmonary disease (COPD) were excluded from the study. Patients were assigned to two groups. Group 1 underwent IPOM with the closure of the defect, and Group 2 underwent IPOM without the closure of the defect. Patients were observed for immediate postoperative complications. Patients were monitored for one year to assess recurrence through clinical evaluation and ultrasonography. Results In this study, seroma formation was found in 3 (7.14%) patients for laparoscopic IPOM with fascial defect closure and 10 (23.81%) in those undergoing laparoscopic IPOM without defect closure (P -value = 0.035). Recurrence was identified in 2 (4.76%) patients undergoing laparoscopic IPOM with fascial defect closure and 9 (21.43%) in those undergoing laparoscopic IPOM without defect closure (P -value = 0.024). Conclusions This study concluded that the frequency of recurrence is less after laparoscopic IPOM with fascial defect closure in midline ventral hernia repair than after laparoscopic IPOM without fascial defect closure.
