BACKGROUND Colonoscopy is widely used for examination,diagnosis,and treatment because of its low incidence of associated complications.Post-colonoscopy appendicitis(PCA)is very rare and is easily misdiagnosed as electrocoagulation syndrome or colon perforation.Therefore,clinicians should pay close attention to this complication.CASE SUMMARY A 47-year-old female patient underwent a colonoscopy for a systematic physical examination,and the procedure was uneventful with normal endoscopic and histologic findings.However,the bowel preparation was suboptimal(Boston 2-3-2).After the examination,the patient experienced pain in the lower abdomen,which progressively worsened.Computed tomography of the lower abdomen and pelvis revealed appendiceal calcular obstruction and appendicitis.As the patient refused surgery,she was managed with antibiotics and recovered well.CONCLUSION In the current literature,the definition of PCA remains unclear.However,abdominal pain after colonoscopy should be differentiated from acute appen-dicitis.
