Hand-assisted laparoscopic aortoiliac surgery: preliminary report of 25 cases

Laparoscopic Vascular Surgery: A Systematic Review

OBJECTIVE

The objective of this systematic review is to evaluate the results of clinical studies on laparoscopic surgery for aorto-iliac disease.

METHODS

A systematic review of the literature from 1966 to September 2006 on laparoscopic and robotic vascular surgery was performed. Only patient series containing more than 5 cases were included. Operative, clamping and anastomosis times, conversion, mortality and morbidity and hospital stay were evaluated.

RESULTS

Thirty studies were identified. These were all descriptive and included 9 comparative studies. Operative times varied widely, the shortest being for hand-assisted procedures (2.5-4 hours) and the longest for totally laparoscopic procedures (4-6.5 hours). Clamping times were all<1 hour in hand-assisted procedures while in other techniques clamping times from 1-2.5 hours were seen. The conversion rate varied from <5% up to 16% in smaller series. The mortality rate was approximately 5% and frequently caused by cardiac ischemia. A variety of problems ranging from minor local wound problems to cardiopulmonary- and renal insufficiency, bleeding, ureter lesions and graft thrombosis were described. Mean hospital stay for nearly all procedures was <1 week.

CONCLUSIONS

Experience of laparoscopic surgery for aorto-iliac disease is still limited. Most study results are biased by patient selection. Only a few surgeons have mastered the required surgical technique and more data are needed to asses the clinical potential of this type of surgery, in comparison with the endovascular alternative. For wider implementation simplification of the surgical procedure seems necessary.

Hand-assisted Laparoscopy Versus Conventional Median Laparotomy for Aortobifemoral Bypass for Severe Aorto-iliac Occlusive Disease: A Prospective Randomised Study

OBJECTIVES

To demonstrate that hand-assisted laparoscopy for aortofemoral bypass for severe aorto-iliac occlusive disease reduces morbidity with earlier recovery of bowel function and shorter in-hospital stay.

DESIGN

Randomised controlled trial.

MATERIALS AND METHODS

Thirty-six consecutive patients with severe aorto-iliac occlusive disease (TASK C/D) without history of major abdominal surgery necessitating an aortobifemoral bypass were randomised between a hand-assisted laparoscopic (HALS) approach and a conventional medial laparotomy. Operative data, early recovery data, quality of life and vascular outcome were analysed.

RESULTS

No significant differences in operative data were found. Fluid and solid diet were resumed earlier (28.8 hrs vs. 76.9 hrs; p = 0.016) (45.6 hrs vs. 105.6 hrs; p = 0.02) and in-hospital stay was shorter (7.5 vs. 8.9 days; p = 0.005) in the HALS group. Six weeks post-operatively social functioning measured by the SF-36 survey score was better in patients randomised to HALS (p=0.023).

CONCLUSIONS

HALS is a less invasive approach for aortofemoral bypass.

Hand assisted laparoscopic surgery of aortoiliac occlusive disease: initial results

OBJECTIVES

Open aortobifemoral bypass grafting has been the procedure of choice for many years in patients with symptomatic aortoiliac occlusive disease (AIOD). Hand assisted laparoscopic surgery (HALS) for AIOD could have advantages like faster recovery, faster oral intake and shorter hospital stay compared to the conventional technique. We documented the results of patients who underwent HALS for AIOD in our hospitals.

MATERIALS AND METHODS

from January 1999 to December 2002, 33 consecutive patients underwent HALS for AIOD. Peri- and postoperative results were prospectively registered. Three different laparoscopic approaches were applied: transperitoneal, retroperitoneal and apron approach.

RESULTS

There were 23 males and 10 females, with a mean age of 59 years (range 39-85). The surgical technique applied was: transperitoneal: 22 patients, retroperitoneal: 7 patients, apron: 4 patients. Per-operative results (median) of the transperitoneal, retroperitoneal and apron approach are: operating time 240, 420 and 263 minutes, cross clamp time 32.5, 40 and 33.5 minutes, blood loss 1150, 2100 and 950 ml, respectively. Postoperatively oral intake was fully resumed in 3, 4.5 and 2 days after performing the transperitoneal, retroperitoneal and apron technique. During the ICU stay patients received artificial respiration for 0, 1 and 0 days, admission to the ICU was 0.5, 1 and 0.75 days for the transperitoneal, retroperitoneal and apron approach. Finally, hospital stay was 8, 12.5 and 7 days after the transperitoneal, retroperitoneal and apron approach. Four patients (12%) had a minor complication, 4 patients (12%) had a major complication; pneumonia with ARDS, sepsis, bypass occlusion and chylo-abdomen. No patients died.

CONCLUSIONS

HALS for AIOD is a technically demanding operation with a long learning curve. All three approaches are feasible. In this series of patients, we feel the transperitoneal and apron approach have the most advantages because of the larger working space. Finally, randomized trials will determine if laparoscopic assisted or total laparoscopic aortoiliac surgery has the potential to reduce morbidity for the patient compared to the conventional technique.

Total Laparoscopic Aortobifemoral Bypass

AIM

To assess the feasibility of aortobifemoral bypass by a laparoscopic approach.

MATERIAL AND METHODS

During November 2002 through July 2003 a total of 21 patients with aorto-iliac occlusive disease underwent total laparoscopic aortobifemoral bypass surgery.

RESULTS

The median operative time was 240 (range 150-420) min with a median aortic cross-clamp time of 60 (30-120) min. Operating time was reduced with experience. The median blood loss was 500 (100-2500) ml. One conversion to open surgery for acute dilation of the small bowel was necessary. Post-operative complications occurred in five patients (coagulation problems, disseminated intravascular coagulation secondary to thrombosis of the left limb, cerebro-vascular accident, dyspnoea, lymph leak) and there was no peri-operative death. Median hospital stay was 7 (5-30) days.

CONCLUSION

Aorto-bifemoral bypass using a total laparoscopic approach can be performed safely. As all new techniques, a learning curve is observed. This new technique should be evaluated in a larger randomised trial to assess its clinical value in comparison to conventional surgery.
