Background: Component separation (CS) for tension-free approximation of fascial edges is the established technique for the repair of large ventral hernias mostly regarding midline defects. Recent studies suggest lower complication rates following a modified version of this technique using a partially endoscopic-assisted approach, whereas little is known about the quality of life (QoL) in the long-term evaluation of these patients.
Methods: A retrospective study and analysis of patients undergoing hernia repair using an open CS (OCS) and endoscopically assisted CS (ECS) technique, respectively, from 2011 to 2016 at the Rostock University Medical Center. Patients underwent a mesh-based sublay reinforcement following a distinct CS with closure of the linea alba. Patient characteristics, technical details, and short-term postoperative outcomes were determined by a physician chart review. A health-related QoL survey (EQ-5D) including a pain assessment was evaluated at a median of 19.5 months postoperatively.
Results: Thirty-five patients had a CS: 25 OCS and 10 ECS. Perioperative variables were comparable except for the median defect size (169 cm2 OCS vs. 86 cm2 ECS; p < 0.05) and maximum width of hernia (25 vs. 13 cm). Hospitalization lasted 16.6 days in the OCS group and 7.9 days in the endoscopic group (p = 0.04). Wound complications occurred in 24% of OCS and 10% of ECS patients.
Conclusions: Patients in the ECS group had a shorter hospital stay and less minor and major wound complications. These advantages led to a faster recovery directly affecting the QoL in the ECS group. This effect diminishes in the long-term follow-up with a positive trend towards the OCS technique.
