A Case of Ascending Colon Stricture Following Appendicitis with Abscess Formation.

Colonic stricture secondary to appendicitis is exceptionally rare. We report a unique case of ascending colon stricture developing one year after treatment for complicated appendicitis in a patient on long-term hemodialysis. A 68-year-old male with a 26-year history of hemodialysis underwent percutaneous drainage for appendicitis with abscess formation, followed by an interval laparoscopic appendectomy. One year postoperatively, he developed nausea and vomiting. Colonoscopy revealed a circumferential stricture in the ascending colon without mucosal abnormalities. A contrast enema demonstrated a 2 cm apple-core stricture. Laparoscopic right colectomy was successfully performed despite extensive adhesions. Histopathological examination confirmed chronic inflammatory stricture with submucosal fibrosis and no evidence of malignancy. The patient recovered well with the resolution of symptoms. This case demonstrates that complicated appendicitis with abscess formation can cause delayed colonic stricture, particularly in immunocompromised patients such as those on chronic hemodialysis. Clinicians should be aware of this potential delayed complication when managing patients with a history of complicated appendicitis.
