Core Tip

Core tip: We report a case of a 53-year-old female who underwent colonoscopy and was diagnosed with cecal adenoma. Endoscopic mucosal resection (EMR) was performed, and she experienced right-lower abdominal pain 7 h post surgery. The following day, laboratory tests revealed a neutrophil count of 14144/mm3, and a C-reactive protein level of 2.20 mg/dL. Computed tomography also revealed appendiceal wall thickening and swelling, so acute appendicitis following EMR was diagnosed. Antibiotics were initiated leading to total symptom resolution, and the patient was discharged on the sixth post-operative day. Acute appendicitis following EMR is rare, and cecal EMR may be a rare cause of acute appendicitis.
