A 70-year-old male underwent endoscopic resection for an adenoma in the ascending colon in February 2013. At the end of December 2014, he was admitted to our hospital with a complaint of right lower abdominal pain and fever. CT showed swelling of the appendix-and a clip in the appendix lumen；the patient was hospitalized with a diagnosis of acute appendicitis. We began conservative treatment with antibiotic medication, but his symptoms did not improve. Five days after admission, we performed emergency surgery. The appendix was found to be swollen and surrounded by an abscess. The middle portion of the appendix had severe inflammation due to incarceration of the clip. We performed an appendectomy and drainage. Although adverse events due to a dropped clip are extremely rare, it may cause acute appendicitis due to incarceration in the appendix as in this case.
