With increasing multidisciplinary management and emphasis on masterly inactivity for abdominal fibromatosis (AF), the indications for surgery are evolving. This retrospective analysis looked at outcomes following surgery. Two groups of patients who underwent surgery for AF between November 2011 and August 2021 were identified—intra-abdominal fibromatosis (IAF) and abdominal wall fibromatosis (AWF). All treatment-related details and follow-up data were gathered from a database and analyzed. Sixteen patients underwent surgery for IAF. R0 resection (wide margin) was achieved in 13 patients (81.2%). Over a median follow-up period of 51.7 (range 5–103) months, 5 patients developed recurrence (31.2%). The conditional probabilities of OS and DFS at 5 years were 80% (95% CI 58.7–100) and 42.2% (95% CI 20.3–87.8), respectively. Ten patients with AWF underwent surgery. R0 resection was achieved at 70% (7/10). Over a median follow-up period of 54.8 (range 12.9–96.7) months, 2 patients (20%) developed recurrence. The conditional probabilities of OS and DFS at 5 years were 88.9% (95% CI 70.6–100) and 77.8% (95% CI 54.9–87.8), respectively. Surgery has a vital role in the management of AF presenting with progressive/symptomatic lesions, especially when watchful waiting is not an option, and must be considered as one of the first-line active therapy. Timely curative surgery avoids disease progression and its morbidity with acceptable recurrence rates and provides durable remissions.
