title: Laparoscopy and major retroperitoneal vascular injuries (MRVI).
abstract: Injury to major retroperitoneal vessels is a potential serious complication of laparoscopy occurring when the Veress needle or trocar is inserted. This report is a review of major retroperitoneal vascular injuries (MRVI) occurring during laparoscopy, as these injuries have not been well documented in the literature. A retrospective, observational review of general surgical laparoscopy cases was conducted over a 3.5-year period in three community, university-affiliated hospitals. We identified 4 MRVI in 3591 laparoscopic procedures. These cases were critically analyzed and compared. The incidence of MRVI was approximately 0.1%. All cases occurred with the closed (blind) insertion technique of Veress needle and primary trocar insertion technique with disposable "safety" shield trocars. All patients sustaining MRVI had acute hypotension introperatively and significant blood loss necessitating postoperative transfusions. Recognition and rapid conversion to laparotomy are keys to enhancing outcome. There is significant potential for morbidity and mortality with laparoscopic MRVI, although each patient in this series was discharged without obvious short-term problems. The advantages of an open approach for primary trocar insertion are numerous and should alleviate the risk of MRVI associated with general laparoscopic surgery.
