Foreign bodies in the colon are encountered with increasing frequency, but, to date,
only sporadic reports concerning their management have appeared in the literature
[1]
[2]
. While most ingested foreign bodies usually pass through the gastrointestinal tract
uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal
perforation and may even result in death [3].
We describe the case of a woman with abdominal pain caused by a toothpick perforating
the sigmoid colon. The foreign body was diagnosed and removed during colonoscopy after
abdominal exploration and appendectomy had not disclosed any abnormalities.
A 52-year-old woman with a 2-week history of upper and lower abdominal pain was admitted
with acute pain in the right lower quadrant. A presumptive diagnosis of appendicitis
was made, and the patient underwent emergency laparotomy. The appendix was normal,
and an abdominal exploration disclosed no abnormalities. Postoperatively, the symptoms
remained with progressive abdominal distension and pain, and were followed by the
appearance of rectal bleeding. A colonoscopy was performed 10 days after laparotomy
and revealed a fixed sigmoid loop with a toothpick of 9 cm length that had perforated
the sigmoid colon (Figure [1]). The toothpick was removed using foreign-body extraction forceps (Figure [2]). Although the abdominal radiograph showed free air as a sign of perforation, the
patient9s recovery was uncomplicated, with antibiotic therapy. The perforation edges
were closed primarily. The circumstances of the foreign body ingestion remained unclear.

This case emphasizes the uncommon but potentially lethal hazards associated with the
ingestion of toothpicks. Such sharp objects may cause localized acute inflammatory
mass or acute diffuse peritonitis and present with signs of an acute abdomen or an
appendicitis. If this unusual but important cause of abdominal pain is taken into
account and diagnosed in time, endoscopic management is possible.
