Abstract

Morgagni hernia (MH) is a rare diaphragmatic hernia which needs surgical repair. The conventional reconstruction involves reduction of hernia, closure of the defect and placement of an intraperitoneal onlay mesh often using robotic platform for ease of dissection and suturing the mesh (r-IPOM). We propose a novel robotic preperitoneal repair (r-TAPP) of MH in four cases and compare them with conventional r-IPOM technique. Between August 2017 and August 2020 nine patients underwent repair of MH. Five cases underwent repair by r-IPOM (group I). For the other four cases, r-TAPP was used (group II). Among the nine cases, the mean age was 53 years in group I and 55 years in group II, mean defect size was 33 mm in group I and 55 mm in group II. Operative time was longer in group II compared to group I (220 min vs 135 min, p = 0.022). Mean length of hospital stay was 1.3 days in group I compared to group II (4.5 and 4.5 vs 1.3 days, p = 0.03). There was statistically significant difference in reduced post-operative pain and time to return to work in group II compared to group I. There was no difference in complications, 30-day readmissions or recurrence of hernia between the two groups. We conclude that compared to the conventional r-IPOM repair, the r-TAPP technique is associated with less pain, early discharge, and faster return to work, translating into overall cost savings for the hospital.
