Abstract
A 35-year-old man had undergone ventriculoperitoneal (VP) shunt placement and chemoradiotherapy for pineal tumor-associated hydrocephalus at 19 years of age, and had shown no disease recurrence. In February 2010, he experienced disturbed consciousness and gait impairment, and visited a local clinic. A cranial CT scan revealed hydrocephalus, and he was referred to the department of neurosurgery of our hospital. Plain X-ray examination of the head showed VP shunt catheter disconnection, and abdominal plain X-ray examination and CT scan revealed that the VP shunt catheter had disconnected and migrated into the peritoneal cavity. The patient underwent single port laparoscopic removal of the catheter. Single incision laparoscopic surgery is considered to be minimally invasive and useful in the present case.
