Case report: successful endoscopic treatment of a large bowel perforation caused by chicken bone ingestion

Abstract Rationale: Large bowel perforations by a foreign body are rarely diagnosed pre-operatively due to non-specific clinical symptoms. The safety and efficacy of foreign body removal via upper endoscopy is well-established and strongly recommended. There is far less experience of endoscopic treatment of sharp foreign bodies impacted in lower parts of gastrointestinal tract. Patient concerns: The patient was 78-year-old female with abdominal pain and nausea. Symptoms had begun 48 hours prior to hospital admission. She had lost over 10 kg of body weight in the previous couple of months Diagnosis: A multidetector-row computed tomography (MDCT) examination of the abdomen revealed mural thickening and enhancement of the cecum with haziness and linear areas of high attenuation in the pericecal fat tissue. A colonoscopy showed, the clear presence of a sharp 5.5-cm-long chicken bone perforating the cecal wall at the antemesenteric site close to the Bauchini valve. Interventions: A quarter of the bone that had penetrated the cecal wall was pulled out with a flexible colonoscopy using a polypectomy snare. Due to the form and length of the bone, it was withdrawn through the entire colon, using pointed end trailing. Outcomes: The patient was discharged three days after colonoscopy with normal laboratory results and without any pain. Lessons: In cases where sharp foreign bodies stuck into the large bowel, it is highly advisable to try to remove them via colonoscopy, before deciding to resolve the issue through a surgical intervention.
