title: Esophageal intramural pseudodiverticulosis associated with esophageal perforation.
abstract: We report a rare case of esophageal intramural pseudodiverticulosis with lower esophageal stricture which perforated into the peritoneal cavity after the patient vomited. A 61-year-old man was admitted with severe chest and epigastric pain after dysphagia and vomiting. Under a diagnosis of upper gastrointestinal perforation, laparotomy was performed. The anterior wall of the abdominal esophagus was found to have ruptured, and proximal gastrectomy with abdominal esophagectomy was performed. Histological examination revealed esophageal intramural pseudodiverticulosis with esophageal stricture distal to the site of rupture, and postoperative endoscopy showed diffuse pseudodiverticulosis in the remaining esophagus. The patient is free of symptoms 5 years after the surgery. This case suggests that careful treatment may be indicated in patients with esophageal intramural pseudodiverticulosis with stricture and elevated intraluminal pressure, to minimize the possibility of severe complications such as esophageal perforation.
