Mesh-reinforced reconstruction after abdominal wall desmoid tumor resection: a retrospective analysis of 16 cases.

Purpose: Managing the defect after abdominal wall desmoid tumor resection is challenging due to the wide excision required. This report aims to review our institutional experience with mesh-reinforced reconstruction following desmoid tumor resection in the abdominal wall.

Methods: We retrospectively reviewed patients who underwent abdominal wall desmoid tumor resection with mesh-reinforced reconstruction between April 2014 and January 2019. Patient records were analyzed to collect data on demographic characteristics, surgical procedures, and complications.

Results: Sixteen eligible patients were identified, including one patient who underwent simultaneous resection of affected intra-abdominal organs. The mean size of the abdominal wall defect was 88.1 ± 71.6 cm², and the mean mesh size was 160.3 ± 56.5 cm². The mean operative time was 87.5 ± 41.4 min, the mean hospital stay was 15.7 ± 6.0 days, and the mean follow-up period was 83.8 ± 18.0 months. Complications included seroma (n = 1) and abnormal sensation (n = 2). Tumor recurrence was observed in 1 patient, who died due to cancer progression (lung cancer). No surgical site infections or mesh infections were observed. Additionally, no patients developed ventral hernias or abdominal bulging.

Conclusion: Mesh-reinforced reconstruction is a feasible and effective approach for patients requiring abdominal wall desmoid tumor resection.
