Abstract Background Cholesterol crystal embolism (CCE) is caused by small crystals of cholesterol dispersed from atherosclerotic plaques of the aorta. There is an increasing interest in CCE because of the increased use of endovascular treatments. Here, we report a rare case of intestinal stenosis caused by CCE after functional end-to-end anastomosis (FEEA). To our knowledge, this is the first report of CCE causing such an anastomotic stenosis. Case presentation A 77-year-old male patient underwent laparoscopy-assisted low anterior resection and protective ileostomy for rectal carcinoid tumor. He was admitted to our hospital with ileus 1 year after stoma closure. Eosinophils and creatine kinase level were slightly elevated. Computed tomography revealed a stricture with thickened intestinal wall just distal to the anastomosis site of the ileostomy. The wall of the descending aorta appeared shaggy due to thrombosis. The patient underwent laparoscopic small-bowel resection because ileus reoccurred after any oral intake. Histopathological findings of the resected specimen showed fibrotic changes distal to the anastomosis site, and needle-shaped cholesterol embolus was observed in the submucosal layer. Thus, the stenosis was considered to be caused by CCE. Conclusion This appears to be the first published report of stenosis due to CCE at such an anastomotic site. Intestinal CCE is difficult to diagnose preoperatively and is associated with poor prognosis. If eosinophilia is present or shaggy aorta is observed, CCE should be suspected to make correct diagnosis and prevent recurrence of CCE. |
