Rationale:Ulcerative colitis (UC) is a chronic, nonspecific, inflammatory disease of the colon. Colorectal is the main target organ of UC, while other digestive tract involvement is rare. This report describes 2 rare cases of duodenal mucosa lesions in patients with UC after total colectomy.Patient concerns:In case 1, a patient of 45-year-old with intermittent diarrhea and bloody mucosanguineous feces who was diagnosed as UC, revealed diffuse erosive ulcers in the descending duodenum through gastroscopy after total colectomy. In case 2, a 55-year-old Chinese female with UC, aggravated to colon cancer and received total colectomy. Eighteen months after surgery, the patient was admitted to hospital following upper abdominal pain and acid regurgitation. A gastroscopy found inflammation in the descending part of the duodenum.Diagnosis:UC, duodenal mucosa lesionsInterventions:In case 1, the patient was treated with oral mesalazine (1 g/tid) and hydrocortisone (0.3 g/d) but symptoms did not improve, and the treatment was changed to oral methylprednisolone (0.6 g/d) and a hydrocortisone enema (0.1 g/late). Finally, the patient underwent a total colectomy and ileostomy. In case 2, the patient was treated with sulfasalazine, mesalazine, and intermittent hormone enemas. A total colectomy and ileostomy were performed with the patient after diagnosed as colon cancer. After surgery, the patient received N1-(2 tetrahydrofuryl)-5-fluorouracil (FT-207), 8 g, 300 mg, and 100 mg oxaliplatin chemotherapy, and biologic therapy.Outcomes:In case 1, the patient presented with duodenal necrosis and died of septic shock. In case 2, the patient recovered well without recurrence by taking proton pump inhibitor.Lessons:The occurrence of UC related ulcerative gastroduodenal mucosal lesions may be associated with progressing UC or total colitis that does not respond to hormone therapy, leading to requirement of total colectomy.
