[A Case of Strangulation Ileus Caused by Pseudomyxoma Peritonei of Appendiceal Origin].

The patient was a 38-year-old woman who visited our hospital with a chief complaint of abdominal pain. She was diagnosed with strangulation ileus and was subsequently admitted to our hospital to undergo surgery. During the surgical procedure, we observed mucus adhesion accumulating within the peritoneal cavity and identified strangulation ileus resulting from a cord-like structure. We did not observe intestinal necrosis. Given that the appendix was swollen, we made the diagnosis of strangulation ileus caused by pseudomyxoma peritonei of appendiceal origin and performed ileocolic resection. The patient recovered well postoperatively and was discharged on postoperative day 9. Pseudomyxoma peritonei is often diagnosed in patients who present with ascites, abdominal swelling, or appendicitis. This is the first case report of pseudomyxoma peritonei diagnosed in a patient with strangulation ileus.
