Laparoscopic transabdominal lumboperitoneal shunt.

Communicating hydrocephalus can be handled either by the ventriculoperitoneal or, occasionally, the ventriculoatrial shunt. The lumboperitoneal shunt is another option. It does not require a transcranial approach; therefore, it is safer for the patient. We describe a technique that can be performed easily by a skilled laparoscopic surgeon through an anterior approach transabdominally. The lumboperitoneal (LP) shunt is placed laparoscopically under direct videoscopic vision, with the catheter inserted transabdominally through the L3 disc space into the thecal sac. In our patient, the lumboperitoneal shunt was placed at the L3 disc space for communicating hydrocephalus. There were no intraoperative or postoperative complications. The LP shunt can be easily placed by a skilled laparoscopic surgeon. The incidence of infection and complications is lower, and the patency rate is higher. This should be the initial choice for communicating hydrocephalus.

Major vascular injuries during laparoscopic cholecystectomy. An institutional review of experience with 2589 procedures and literature review.

BACKGROUND: Since the introduction of laparoscopic cholecystectomy, major vascular injury has been a rare but very serious complication of the procedure. METHODS: All 2,589 laparoscopic cholecystectomies performed at our institution between May 1, 1990, and December 31, 1996, were retrospectively reviewed to identify major vascular injury and the mechanisms involved. All these procedures were performed either by surgical attendings or senior surgical residents. RESULTS: During the 1,372 operations performed here between May 1, 1990, and May 1, 1994, there were three major vascular injuries. One was to a portal vein, due to dissection during lysis of adhesions; the other two, to the aorta and vena cava, were due to trocar insertions. There was one mortality secondary to liver failure following repair of the portal vein injury. Between May 1, 1994, and December 1, 1996, there were no major vascular injuries; our overall incidence was 0.11%. A review of the literature on this subject is included. CONCLUSIONS: Laparoscopic cholecystectomy is a very safe procedure; major vascular injury is a rare complication, but mandates early recognition and consideration of prompt exploratory laparotomy. These injuries can be avoided by strict adherence to laparoscopic guidelines: obtaining pneumoperitoneum by the open technique, inserting side trocars under direct vision, elevating the abdominal wall prior to trocar insertion, and training surgeons in a laparoscopic laboratory.
