Purpose
Open anterior release of the external oblique fascia to enable midline closure of large abdominal wall defects is associated with relevant morbidity due to extensive subcutaneous dissection. Using endoscopic techniques, wound complications can be minimized. However, identification of the correct entry point (e.g. for balloon trocar insertion) can be challenging especially in adipose patients. We therefore present a technical modification facilitating the entire procedure.
Methods
A novel technique for endoscopic anterior component separation using a trocar system allowing blunt and sharp dissection under direct vision is described. This brief communication also contains our initial experience and learning curve with this novel approach.
Results
Endoscopic release of the external oblique fascia was successfully performed 29 times in a total of 15 patients. Body mass index accounted for 30.8 kg/m2 (median; range 21.6–42.5). Transverse width of midline defect accounted for 7 cm (median; range 4–12). Subsequent hernia repair was successfully done using sublay mesh reinforcement (n = 13) or a laparoscopic intraperitoneal onlay mesh procedure (n = 2) with midline closure in all cases. One hematoma was seen at site of release managed conservatively.
Conclusions
Using a trocar system allowing blunt and sharp dissection under direct vision may be a viable option for the endoscopic anterior component separation.
