Giant Abdominal Wall Desmoid Tumor: Surgical Resection and Combined Reconstruction with Biological and Synthetic Prostheses

Introduction: Desmoid fibromatosis is an extremely rare but locally aggressive soft tissue tumor. When radical resection is indicated, the surgical team faces the challenge of abdominal wall reconstruction, for which optimal technique is still debated. We present the case of a giant abdominal wall desmoid tumor identified in the ante-partum period, showing a growth in the post-partum period which was subsequently resected. Presentation of the case: 37 years old woman suffered from rapidly grew desmoid tumor of abdominal wall explored by CT scan and a biopsy which revealed a large abdominal wall tumor invading completely the right part of abdominal rectus and oblique muscles without developing in the abdominal peritoneal cavity. The 30cm×25cm mass was successfully resected with negative margins. The formed defect was repaired following a combined method using a synthetic bi face mesh Ventra light ST and an absorbable biological mesh Phasix®. The patient had an uncomplicated post-operative course and was discharged on day 14. Discussion: There is no consensus regarding the surgical technique to close the abdominal defects. Nowadays, in the most cases, surgeons use different types of synthetic meshes. The advent of biological matrices has added a valuable option to the field of abdominal wall reconstruction. Conclusion: We present a case of large abdominal wall desmoid tumor excision followed by reconstruction with biological implant.
