Laparoscopic injury of abdominal wall blood vessels: a report of three cases.
BACKGROUND: Operative laparoscopy is being used for an increasing number of applications. Many of these innovative techniques require the insertion of large trocars through the anterior abdominal wall at points lateral to the midline. Because of the rich vascular supply of the anterior abdominal wall, the incidence of abdominal wall vessel injuries appears to be increased by these techniques. CASES: Three cases are reported in which abdominal wall blood vessels were injured during operative laparoscopy. Case 1 describes laceration of the inferior epigastric artery above the pubic crest. Despite initial hemostasis with a transabdominal suture ligation, postoperative blood loss necessitated transfusion and reoperation to control bleeding. Case 2 describes hematoma formation after unrecognized injury to one of the epigastric vessels. The hematoma resolved without sequelae with conservative treatment. Case 3 describes hematoma formation under a laparoscopic trocar incision lateral to the umbilicus that progressed to an abscess and was treated with drainage, irrigation, and antibiotics. CONCLUSIONS: Choosing appropriate trocar types and insertion sites based on a thorough understanding of anterior abdominal wall anatomy may minimize the risk of vessel injury during operative laparoscopy. However, because of anatomical variation, strategies for managing vessel injuries and their sequelae are also necessary.
