Toothpick ingestion complicated by cecal perforation : case report and literature review

Background: Diverticulitis and carcinoma represent the most common causes of colon perforation, but other causes, like ingestion of foreign bodies, should be taken into account. Case presentation: We report the case of a 64-year old man presenting in our Emergency Department with a 2 days history of right lower abdominal pain, nausea, vomiting and low grade fever. Physical examination evocated mild pain with positive rebound tenderness in the right lower abdominal quadrant, and positive right costovertebral angle tenderness. Routine blood tests, abdominal X-rays and CT scan were inconclusive for perforation. At explorative laparoscopy a cecal perforation with localized peritonitis was found, and a right colectomy was performed due to the suspicion of cancer. Histological examination confirmed the presence of a perforation caused by a piece of wood (toothpick) of 6 cm in length. Conclusions: Foreign body ingestion should be taken into account in the evaluation of acute abdominal pain. A detailed patient's history may be crucial for a correct diagnosis and treatment.
