Abstract

Background: The authors analyzed surgical factors and outcomes data in the largest single institutional study comparing endoscopic (ECS) and open component separation (OCS) in ventral hernia repairs (VHR).

Results: Twenty-five ECS patients underwent subsequent laparoscopic hernia repair, and 17 underwent open repair. Operative time for ECS was longer than OCS (334 vs. 239 min; P < 0.001); however, there was no difference in length of stay (4 days in both groups, P = 0.64) and estimated blood loss (ECS: 97 vs. OCS: 93 cc, P = 0.847). In a sub-analysis of ECS patients, those who underwent laparoscopic hernia repair had a 96 min shorter operative time (P < 0.001) and lower EBL (63 vs. 147 cc, P < 0.001) than open repair. Wound complications were 24 % in the ECS (n = 10) and 32 % in OCS group (n = 11). There was one midline hernia recurrence in the ECS group (mean follow-up of 8 months, range 0.5–34.5 months) and no hernia recurrences in the OCS group (mean follow-up 10 months, range 0.5–30 months). Three of the patients in the ECS group developed new lateral abdominal wall hernias post-operatively.

Methods: A prospectively maintained database was reviewed, identifying 76 patients who underwent component separation for VHR with mesh from 2010 to 2013: 34 OCS and 42 ECS. Comparisons were made for demographics, surgical risk factors, and peri-operative outcomes. Wound complications and hernia occurrence post-operatively were reviewed. Risk analyses were performed to determine the association of pre-operative risk factors with surgical site occurrences.

Conclusions: The ECS group had a significantly longer operative time than the OCS group. Post-operative wound complications were similar between ECS and OCS groups. Patients in the ECS group who underwent subsequent laparoscopic VHR had a shorter operative time and blood loss than open repair.
