Gastrointestinal perforation secondary to accidental ingestion of toothpicks: A series case report

Rationale: Toothpicks are widely used as a tooth cleaning tool after meals in China. Most of the Chinese toothpicks are made of wood or bamboo with a hard texture and sharp ends. This characteristic has proven to be potentially dangerous when toothpicks are accidentally ingested, as they can cause damage and perforation of the digestive tract and other subsequent complications.

Patient concerns: The main clinical complaints of 5 patients in this study were mainly acute or chronic abdominal pain, duration from 2 days to 2 months, 1 case with vomiting, 1 case with fever.

Diagnoses: Four cases were initially diagnosed by computed tomography (CT) scan; However, the first case was misdiagnosed as appendicitis so the patient did not undertake a preoperative CT scan and it was diagnosed by laparoscopy.

Interventions: All the cases were treated by laparoscopy and the toothpicks were removed successfully.

Outcomes: Toothpick-caused digestive perforation was confirmed by laparoscopy in all this 5 cases, the perforation sites were 2 cases at the antrum of stomach, 1 case at the third part of duodenum, 1 case at the ileocecal junction and 1 case at the sigmoid colon. 4 cases had perforation repair . Operative time :48-67 min. Intraoperative bleeding: 25-80 ml. 1 patient had a secondary liver injury. No postoperative complications occurred in all cases. The length of hospital stay was between 4-25 days.

Lessons: Our case series study suggests that laparoscopy is a safe and feasible surgical procedure for definitive management of digestive tract perforation by toothpick ingestion. We also suggest all the people should have healthy life behaviors and use the toothpicks correctly.
