Abstract
BACKGROUND: Radical tumor resection and immediate lower abdominal wall reconstruction in patients with aggressive neoplasm invading full-thickness abdominal wall are challenging because of their close proximity and possible invasion to bone and great vessels, as well as consequent giant defect. METHODS: Data on 16 patients were reviewed retrospectively. Radical neoplasm resection and immediate abdominal wall reconstruction using the combined technique of intraperitoneal mesh placement, sublay technique, pedicled great omentum flap, and rotation skin graft were performed. RESULTS: Sixteen patients underwent radical abdominal wall neoplasm resection, achieving clear margin of >3 cm. The mean size of consequent giant defect was 226.5 ± 65.5 cm(2), with a mean polypropylene mesh size of 160.7 ± 40.5 cm(2) and a mean compound mesh size of 330.8 ± 100.2 cm(2). Sixteen patients had a mean follow-up duration of 32.5 ± 12.5 months. Four patients developed incisional infections, and 1 patient died of several metastatic lesions 24 months postoperatively. No ventral hernia and abdominal wall recurrence were observed. CONCLUSIONS: Radical neoplasm resection and immediate abdominal wall reconstruction are appropriate for patients with aggressive neoplasm in the lower abdominal wall.
