Case Report

A 62-year-old male presented with abdominal pain in the right lower quadrant for 1 day. The patient’s history included an ambulant colonoscopy with no pathological findings 3 weeks prior. Clinical examination revealed tenderness in the right hypochondrium. Moderate inflammation with C-reactive protein 56.6 mg/L but normal white blood cell count was assessed. An enhanced computed tomography scan of the abdomen showed signs of non-specific segmental colitis in the ascending colon (Figure 1). Colonoscopy revealed a perforation of the ascending colon by a double-pointed wooden toothpick (Figure 2).

Figure 2. Colonoscopy showed a wooden toothpick impacted in the ascending colon.

The foreign body was successfully removed endoscopically using a disposable polypectomy snare. After complete removal of the toothpick, the endoscope was withdrawn, re-inserted with a mounted and loaded over-the-scope clip (OTSC) device, and positioned toward the perforation site (Figure 3). After the tissue was grasped with an OTSC anchor, a 9-mm OTSC was released and the perforation site was closed (Figure 4). The postinterventional period was uneventful. Follow-up colonoscopy 2 weeks later revealed no displacement of the OTSC or other complications.

Ingestion of a toothpick is a rare incident, and gastrointestinal (GI) perforation has been reported to occur in 0.2 per 100,000 people every year in the United States.1Extremes of age, personality disorders, mental retardation, artificial dentures, palatal insensitivity, and alcoholism have been described as predisposing factors.2 Diagnosis is difficult due to unspecific clinical findings, and toothpicks were apparent with imaging techniques in only 14% of cases.3 Most patients present with abdominal pain (70%), as our patient did.3 Definitive diagnosis of a toothpick injury is commonly made at laparotomy (53%) followed by endoscopy (19%).3 The most common sites of perforation are the duodenum and sigmoid colon.3 Complications include bleeding, obstruction, fistula formation, sepsis, and death, with an overall mortality of 18%.3,4

In the past, standard treatment for GI toothpick perforation had been surgery. Recently, invasive endoscopic treatment has provided an alternative approach. One of the recently established devices is the OTSC system, which has been developed for hemostasis of GI bleeding as well as closure of iatrogenic perforations of the colon. GI defects <30 mm in diameter can be closed with OTSC.5 Our case report demonstrates the successful endoscopic treatment of a colon perforation caused by a toothpick using the OTSC system, without the need for surgery.
