Abstract
INTRODUCTION: Percutaneous endoscopic gastrojejunostomy (PEG-J) is a convenient and safe enteral feeding tool for patients with oropharyngeal dysfunction accompanied by gastroesophageal reflux. However, serious complications have not been fully characterized. PRESENTATION OF CASE: A 22-year-old man with cerebral palsy was referred to our department with complaints of vomiting and massive bloody stools for 10 h. On imaging examination, strangulated bowel obstruction due to the PEG-J tube was suspected because the tube was located on the right side of the body, and the small intestine was diffusely dilated with a reduced wall contrast effect. Urgent laparoscopy revealed a small bowel volvulus (SBV) twisted 180° clockwise around the superior mesenteric artery, which was repaired manually without intestinal resection. The patient was treated in the intensive care unit postoperatively but required partial ileal resection and colostomy owing to the difficulty in managing watery diarrhea and intestinal infection. The patient was discharged after stoma closure 121 days after initial surgery. DISCUSSION: Although SBV rotated at the site of PEG insertion has been reported as a rare complication, there are no reports of rotation of the PEG-J tube itself associated with SBV. In the present case, abnormal positioning of the PEG-J tube on imaging was helpful for diagnosis. CONCLUSION: SBV should be recognized as a potential complication of PEG-J, since delayed diagnosis can lead to irreversible ischemia of the extensive small intestine.
