Massive gastrointestinal bleeding and obstruction of the ureter caused by the migration of a swallowed toothpick from the sigmoid colon--a case report.
In this study, a case of an ingested toothpick partially migrating from the sigmoid colon, causing massive lower gastrointestinal bleeding due to arterial-colic fistula, and stricture of the left ureter is presented. A 70-year-old male was admitted to the emergency department after having feces mixed with fresh and coagulated blood for the past two days. Computed tomography and retrograde ureteropyelography showed the stricture of the left ureter, 1.5 cm below the branching of iliac artery, without any signs of malignancy. Colonoscopy showed fresh blood in the rectum and sigmoid colon up to the neoplasm like granulation tissue mixed with fresh and coagulated blood, which almost obstructed the lumen. Explorative laparotomy showed a foreign body (toothpick) perforating the sigmoid colon through the mesenterial wall, and being stocked with one-third into the left internal iliac artery, causing arterial-colic fistula. The remaining part of the toothpick was surrounded by granulation tissue and chronic inflammatory process, pressing on the distal third of the left ureter. We conclude that a swallowed toothpick may cause a significant gastrointestinal injury with a wide variety of clinical manifestations, and it must be treated with caution. The imaging studies are often inadequate in detecting toothpicks, and thus, we insist on a physical examination, as the best indicator of injury.
