PMID: 36719329.


A woman in her 70s with a medical history of hypertension and dyslipidemia was admitted for colonoscopy due to long-term abdominal pain. During the procedure, a sharp cylindrical foreign body was identified in the sigmoid colon, imprisoned in two diametrically opposite diverticular orifices, with purulent drainage and exuberant reactive inflammatory tissue in each diverticulum. Carefully mobilization from both diverticular orifices into the colon lumen and safety removal were performed using a rat tooth forceps, without intercurrences. The removed foreign body corresponded to a chicken bone about 3 cm in size. The plain abdominal X-ray had no evidence of pneumoperitoneum. Empirical antibiotic therapy was started with complete resolution of abdominal pain during follow-up. Most foreign bodies lodged in the colon are treated conservatively as they typically pass without intervention, however, they can cause damage to the colonic mucosa and lead to perforation or infections (namely peritonitis, peritoneal abscesses, and fistulas).
