A comparison of total laparoscopic and open repair of abdominal aortic aneurysms

ObjectiveThe feasibility of total laparoscopic abdominal aortic aneurysm (AAA) repair has been well established. In a previous case-control study, we showed that the postoperative courses of total laparoscopic and open AAA repairs were similar. The purpose of this study was to compare the long-term results of these techniques in the same cohort of patients.MethodsThirty patients with AAAs treated by total laparoscopic repair between July 2003 and December 2004 (group I) were matched in a case-control fashion by morphology and American Society of Anesthesiologists class with 30 patients who underwent open AAA repair between April 1997 and May 2004 (group II). Patients who survived the intervention were followed up during 5 years. Follow-up consisted of physical examination and duplex ultrasonography at 1 month and yearly thereafter. Group I patients had an additional control computed tomography scan within the first 3 months postoperatively.ResultsFive-year cumulative survival rates were similar (group I: 83% ± 7% vs group II: 79% ± 7%; log-rank test, P = .69). No late aneurysm-related death occurred during the follow-up period. Incisional hernias were more likely to occur in group II patients (group I: 0% vs group II: 15.4%; P = .047). Incidence of postoperative sexual dysfunction was similar in both groups (group I: 22.2% vs group II: 25.0%; P = not significant [NS]). No late reintervention was recorded in group I, whereas 2 patients in group II had incisional hernia repair. At 5 years, no graft sepsis or anastomotic pseudoaneurysm was reported.ConclusionsThis study suggests that total laparoscopic AAA repair provides good long-term results, comparable to those of open repair in terms of aneurysm-related mortality and morbidity. It may reduce the incidence of laparotomy-related complications

Total laparoscopic abdominal aortic aneurysm repair with reimplantation of the inferior mesenteric artery

AbstractWe performed a total laparoscopic reimplantation of the inferior mesenteric artery (IMA) during laparoscopic infrarenal aortic aneurysm repair. The postoperative course was uneventful, and angiograms showed a patent IMA after reimplantation. To our knowledge, total laparoscopic reimplantation of the IMA in human beings has not previously been described
