An overview of laparoscopic techniques in abdominal aortic aneurysm repair.
BACKGROUND: Since 1993, various laparoscopic techniques have been developed to make laparoscopic treatment of abdominal aortic aneurysms (AAAs) a possible therapeutic alternative. We aim to review all published clinical studies on laparoscopic surgery of AAAs and juxtarenal abdominal aortic aneurysms (JAAAs). METHODS: A thorough search of English-language literature published between January 1966 and December 2012 was performed. Studies that reported the results of laparoscopic surgical procedures as the intended repair strategy in patients with AAAs and JAAAs were selected using specific inclusion criteria. Only case series containing more than five patients were included. Outcome measures of eligible studies were extracted, tabulated, and then analyzed cumulatively, using a purely descriptive approach. RESULTS: Fourteen studies were included in the analysis encompassing 933 patients with AAAs (mean age, 68.5 years; age range, 46-88) averaging 55.8 mm in diameter and 96 patients with JAAAs (mean age, 71 years; age range, 50-81) averaging 57 mm in diameter. The mean follow-up was 15.3 months for the AAA cases and 32.8 months for the JAAA cases. Hand-assisted laparoscopy, in particular, had a low 30-day mortality rate, short cross-clamping and operative times, few perioperative and postoperative complications, high graft patency rates, and short length of both hospital and intensive care unit stay. CONCLUSIONS: Laparoscopic surgical procedures are a safe, feasible, and worthwhile alternative for patients with AAAs and JAAAs. Hand-assisted laparoscopy, in particular, was associated with low morbidity and mortality and short hospital and intensive care unit stay. However, the final decision regarding the best laparoscopic treatment should be left to the surgeon because of the limits of the data.
