Purpose: Surgical repair of complex abdominal wall hernias remains technically demanding and is widely recognized as a risk factor for unfavorable outcomes with high recurrence and morbidity rates. The objective is to assess short- and long-term complications after open intraperitoneal onlay mesh (IPOM) repair combined with bilateral anterior component separation (ACS) for large and difficult incisional hernias, alongside evaluating hernia recurrence rates.
Methods: This retrospective analysis utilized data sourced from Hospital electronic health records and a prospective database at an academic tertiary referral center. Data collection was carried out from patients operated between January 2006 and December 2017. Eligible patients had complex incisional hernias measuring at least 10 cm in their transverse diameter and had an open IPOM repair with bilateral ACS.
Results: In our study group of 45 patients, the 30-day surgical site occurrence (SSO) rate was high (37.8%), primarily consisting of superficial postoperative complications as seroma (17.8%) and wound dehiscence (6.7%). Among six patients (13.3%), wound complications escalated to chronic infected mesh-related problems, leading to complete mesh removal in four cases (8.9%) and partial mesh removal in two cases (4.4%). Regarding long-term complications, five patients (11.1%) developed enterocutaneous fistula. The recurrence rate was modest [5 out of 41 (12.2%)] over a median follow-up period of 99 months.
Conclusions: Despite a high SSO rate, application of the open IPOM technique with ACS could serve as a valuable rescue option for managing large and complex hernias, with acceptable hernia recurrence rates at long-term follow-up.
