Abstract
A 91-year-old man was referred to our hospital with intermittent dysphagia. He had undergone esophagectomy for esophageal cancer (T3N2M0 Stage III) 11 years earlier. Endoscopic examination revealed an anastomotic stricture; signs of inflammation, including redness, erosion, edema, bleeding, friability, and exudate with white plaques; and multiple depressions in the residual esophagus. Radiographical examination revealed numerous fine, gastrografin-filled projections and an anastomotic stricture. Biopsy specimens from the area of the anastomotic stricture revealed inflammatory changes without signs of malignancy. Candida glabrata was detected with a culture test of the biopsy specimens. The stricture was diagnosed as a benign stricture that was caused by esophageal intramural pseudodiverticulosis. Accordingly, endoscopic balloon dilatation was performed and anti-fungal therapy was started in the hospital. Seven weeks later, endoscopic examination revealed improvement in the mucosal inflammation; only the pseudodiverticulosis remained. Consequently, the patient was discharged. At the latest follow-up, the patient was symptom-free and the pseudodiverticulosis remained in the residual esophagus without any signs of stricture or inflammation.
