Peritoneal shunt tube placement performed using an endoscopic threaded imaging port. Technical note

The authors used an endoscopic threaded imaging port that originally was developed for laparoscopy to access the peritoneal cavity, and applied this device to the placement of a peritoneal shunt tube in patients suffering from hydrocephalus. Using this system, the peritoneum can be opened quickly under direct vision by using an endoscope through a small skin incision. The peritoneal cavity is secured by replacing the cannula with a polyvinyl chloride (PVC) tube. At the end of surgery, the terminal end of the shunt tube is inserted through the PVC tube, which serves as a guiding catheter. Only one or two skin stitches are needed for closure. This method has proved to be safe, quick, and less invasive than conventional minilaparotomy.
