CASE REPORT A 59-year-old man was referred for colonoscopy to evaluate a complaint, approximately 6 months in duration, of intermittent left lower quadrant discomfort and a finding of fecal occult blood. His past medical history included hypertension and mild depression, with no history of previous surgical procedures. The patient was taking fluoxetine and diltiazem, had a 40 pack-year history of tobacco use, and consumed small amounts of alcohol infrequently. Review of systems was negative for melena, gross blood per rectum, fever, weight loss, or change in bowel habits or stool caliber. The patient's only additional complaint was increased flatus during the last month. Physical examination revealed a moderately obese man, with upper dentures in place. Vital signs were normal, and he was in no evident discomfort. General examination was normal except for the abdomen, which revealed mild discomfort to deep palpation in the left lower quadrant. There were no palpable masses, and no guarding or peritoneal signs. Colonoscopy disclosed sigmoid diverticulosis and a foreign body at approximately the mid-sigmoid level. A toothpick was noted to be lodged in the lumen with surrounding erythema and edema (Fig. 1). One end was impacted within a diverticulum and the other in the wall opposite.

GASTROINTESTINAL ENDOSCOPY
Figure 1, Endoscopic view of toothpick impacted in wall of sigmoid colon. Gentle probing with a biopsy forceps freed one end, which was then grasped and cautiously removed from the diverticulum. On extraction, purulent fluid flowed immediately from a small divot in the bowel wall. On colonoscopic delivery of the 6.7 • 0.2 cm wooden toothpick per anus, the patient noted a dramatic and immediate decrease in his left lower quadrant discomfort. Subsequent questioning yielded no history of known toothpick ingestion or of meals served with toothpicks, and the patient did not chew on toothpicks. At the conclusion of the procedure, the patient was given one dose of ampicillin]sulbactam. He was advised to continue parenteral antibiotic therapy and remain under observation for 24 to 48 hours; an abdominal CT was ordered. However, the patient left the hospital against medical advice within 5 hours; he was given oral antibiotics on discharge. Four days after leaving the hospital, the patient presented again, this time with complaints of 2 days of watery diarrhea and low-grade fever. He was found to have a temperature of 101~ a normal examination of the abdomen, and a white blood cell count of 19,000/mm 3 (normal value 4800 to 10,000/mm3). CT of the abdomen and pelvis showed sigmoid diverticulosis and significant fluid and fat stranding in the proximal sigmoid flexure, with a localized pneumoperitoneum walled off by omentum (Fig. 2). Treatment with broad spectrum parenteral antibiotics was reinstituted and continued for 7 days. The patient had an uneventful hospital course; the white blood cell count returned to normal within 72 hours. A follow-up CT 4 days later revealed interval improvement. The patient did well after discharge. A follow-up CT 9 weeks later showed complete resolution of the inflammatory process.

Brief Reports
tion, peritonitis, or an obstructive process. Some m a y present with features mimicking appendicitis or ileitis. 2 A large n u m b e r of reports support the belief t h a t perforation is more common with sharp or pointed objects such as chicken or fish bones, metal objects, and wooden splinters. One 4-year survey found 8176 toothpick-related injuries in the United States, a rate of 3.6/100,000 persons/year. Five percent of these injuries involved i n t e r n a l organs. 3 Toothpick ingestion appears to be commonly implicated in intestinal perforations due to the length and bilateral pointed ends of this foreign body. The consequences of impaction in the GI tract have been commented on since at least 1941, when it was reported t h a t 9% of perforations in one series of ingested foreign bodies were due to wood splinters, toothpicks, or pencils. 4 Historically, toothpick impaction in the lower GI tract has been m a n a g e d by early surgery. As the devices and skills of the endoscopist improve, this approach to m a n a g e m e n t should be reconsidered. One review of a 10-year experience with 101 foreign body ingestions in 100 patients showed t h a t the choice of management among the available options of serial radiographic evaluation, endoscopic retrieval, and operative intervention was based, in part, on whether the foreign body lodged in the esophagus, passed easily to the stomach, or was suspected of causing "impending" perforation. 5 Admittedly, impending perforation was diagnosed with difficulty in most cases. Half of the patients undergoing surgery (or 6% of the total in the study) were asymptomatic at the time and some, in retrospect, might have been candidates for nonsurgical management. With little data on colonoscopic retrieval in such cases, it is difficult to establish definitive guidelines. Obviously, operative removal of a frankly perforating toothpick is prudent, but it appears that in some cases endoscopic intervention m a y be accomplished at acceptable rates of morbidity and mortality. Several case reports describe endoscopic removal of toothpicks from the duodenum, appendix, transverse colon, and rectum.6-9 Rex and Bilotta 1~ described 2 patients with chicken bones impacted in the sigmoid colon, w i t h o u t peritoneal signs, who were successfully m a n a g e d colonoscopically. Another report of successful endoscopic diagnosis and t r e a t m e n t of a chicken bone ingestion by Tarnasky et a1.11 illustrates several factors strongly associated w i t h foreign body inges-
