A Giant Mesenteric Fibromatosis Case Presenting with Mechanical Intestinal Obstruction and Successfully Resected with Partial Duodeno-Jejunectomy and Right Hemicolectomy

The term "desmoid" was coined by Muller in 1838 and is derived from the Greek word "desmos", meaning band or tendon. 1 Mesenteric fibromatosis accounts for approximately 0.03% of all malignant and benign neoplasms. 2It often arises from the abdominal wall or the extremities of parous women.It can also originate, though rarely, from the mesentery. 3It may be locally aggressive but does not metastasize.Its biological behavior is similar to that of fibrous lesions and fibrosarcoma.The most common symptoms are abdominal pain, nausea, vomiting, abdominal mass on palpation, weight loss, and fever.The tumor may lead to complications such as small bowel or ureteric obstruction, intestinal perforation, enterocutaneous fistula, and intestinal hemorrhagia. 4,5 57-year-old male presented to our hospital with complaints of abdominal pain, vomiting, distension, and swelling.The patient had been suffering abdominal discomfort for five years and had undergone two colonoscopic examinations in those five years, but no disorders had been found.Abdominal examination revealed distension, a metallic sound, muscular rigidity, and tenderness.X-ray examination revealed multiple air-fluid levels (Figure 1).An abdominal ultrasound showed a large solid mass in the right upper quadrant of the abdominal region.Since the intravesical pressure was measured as 25 cm H 2 O, the patient was diagnosed with mechanical intestinal obstruction, and laparotomy was performed
