Duodenal perforation as a postoperative complication after ventriculoperitoneal shunt: A case report

Ventriculoperitoneal shunt (VP shunt) is the one of the most common and important tools for the treatment of hydrocephalus. It requires simple technique and demonstrates effectiveness in treating hydrocephalus. However, many complications have been reported such as infection, valve obstruction, valve dysfunction and abdominal complications. Complications of intestinal perforation and catheter penetrating the intestine are very rare, accounting for 0.01-0.07% of abdominal complications. In the literature, 94 cases of intestinal perforation and catheter penetration and only 2 cases of duodenal perforation have been reported.

In this study, we report a successful surgical treatment of a duodenal perforation complication after 5 months of VP shunt. Gastroscopy showed the distal tip penetrating into the D2 segment of the duodenum. Surgery was performed to relocate the abdominal tip and to repair the perforation. Meningitis was treated with antibiotics. The patient was stable and discharged after 3 weeks.

The epidermiology, presentation and diagnosis and strategy of treatments as well as their outcomes were discussed.

Intestinal perforation with VP shunt catheter is rare. Diagnosis is simple if the catheter comes out of the anus, mouth, vagina, penis, scrotum, navel. In case when the catheter is inside the lumen of the gastrointestinal tract, diagnosis often requires imaging such as abdominal computed tomography, and gastrointestinal endoscopy. Surgery treatment was to replace the drainage valve and to close the perforation the digestive tract.
