Abstract
BACKGROUND: We present a comparative series to utilize minimally invasive endoscopic, total extraperitoneal laparoscopic (TEP-lap), and transabdominal preperitoneal robotic perforator (TAP-RAP) harvest of the deep inferior epigastric (DIE) vessels for autologous breast reconstruction (ABR) to mitigate donor site morbidity. We hypothesized that TEP-lap and TAP-RAP harvests of abdominal-based free flaps are safe techniques associated with decreased fascial incision when compared with the endoscopic harvest.
METHODS: We designed a retrospective cohort series of subjects with newly diagnosed breast cancer who presented for ABR using endoscopic (control), laparoscopic, or robotic assistance between September 2017 and April 2019. The primary outcome variables were flap success (i.e., absence of perioperative flap loss), fascial incision length, and intraoperative complications. Secondary variables included operating time, costs, and postoperative complications within 90 days (arterial thrombosis, venous congestion, bulge/hernia, and operative revision). Exclusion criteria included < 90 days follow-up.
RESULTS: In total 94, 38, and 3 subjects underwent endoscopic, TEP-lap, and TAP-RAP flap harvests. Mean lengths of fascial incisions for the endoscopic and laparoscopic cohorts were 4.5 ± 0.5 cm and 2.0 ± 0.6 cm (p < 0.0001), while incision length depended on the concurrent procedure in the robotic cohort. No subjects required conversion to an open harvest. There were no bleeding complications, intra-abdominal injuries, flap losses, or abdominal bulges/hernias noted in the TEP-lap and TAP-RAP cohorts.
CONCLUSION: Minimally invasive DIEP flap harvest may decrease fascial injury when compared with conventional open harvest. There are significant trade-offs among harvest methods. TEP-lap harvest may better balance the trade-off related to abdominal wall morbidity.
