Spontaneous Regression of Polyposis following Abdominal Colectomy and Helicobacter pylori Eradication for Cronkhite-Canada Syndrome

Abstract

The etiology of Cronkhite-Canada syndrome (CCS) remains unknown and many cases are refractory to treatment. Therefore, new therapies are urgently needed. Furthermore, a number of CCS cases with gastrointestinal carcinoma have been reported. Our patient had rapid onset of CCS and early development of colon carcinoma associated with adenomas. High anterior resection of the sigmoid colon and ileostomy were performed, and her symptoms and endoscopic and histological findings improved. Helicobacter pylori eradication was carried out 2 years later, surgical closure of an ileal fistula the following year. After 4 months, upper gastrointestinal endoscopy and colonoscopy showed that the CCS lesions had completely disappeared, and biopsies confirmed a normal stomach, duodenum, ileum and colon histologically. The patient has maintained remission for 2 years. The clinical course of this case, showing complete regression of CCS lesions following abdominal colectomy and H. pylori eradication, suggests the significance of H. pylori infection in the treatment of CCS.
