Minimally invasive diagnostic and therapeutic surgery for an intra-abdominal desmoid tumor: A case report.

•Intra-abdominal desmoid tumor is rare with no particular imaging features, so preoperative diagnosis is quite difficult.•R0 resection is essential for treatment but often requires extensive surgical trauma, which can be a risk for recurrence.•A laparoscopic approach for this tumor was effective, with the resulting diagnosis and resection being less traumatic.•The first report of successful laparoscopic complete resection and reconstructive procedures were demonstrated.
