Idiopathic Mesenteric Phlebosclerosis Treated With Laparoscopic Subtotal Colectomy: A Case Report

Idiopathic mesenteric phlebosclerosis is a rare entity characterized by chronic intestinal ischemia due to calcification and obstruction of the mesenteric veins. Here, we report a patient with idiopathic mesenteric phlebosclerosis treated with laparoscopic subtotal colectomy after evaluation by imaging studies. The patient was a 68-year-old Japanese woman with recurrent abdominal pain who had taken a Chinese herbal medicine for more than 20 years. Abdominal CT showed wall thickening of the right colon with calcification of branches of the superior mesenteric vein. Colonoscopy showed cyanotic mucosa from the cecum to the sigmoid colon. The affected area seen on colonoscopy extended to the distal colon. Despite discontinuation of the herbal medicine, her symptoms did not improve. Laparoscopic subtotal colectomy was performed. This report highlights the importance of appropriately evaluating the extent of the affected preoperatively area based on findings from colonoscopy, CT, and contrast enema.
