Gasless videoendoscopic implantation of aortobifemoral vascular prostheses via transperitoneal versus extraperitoneal approach in an animal model

Abstract

Gasless videoendoscopic implantation of aortobifemoral vascular prostheses in animal subjects is both practicable and reproducible using either a transperitoneal or extraperitoneal approach. The extraperitoneal approach has proven advantages over the transperitoneal approach. The in vitro fluid tightness achieved with endoscopically sutured aortic end-to-side anastomoses is comparable to conventionally sutured anastomoses.

A model for laparoscopic aortic aneurysm resection

“…Most studies refer to experimental or clinical work for occlusive aortoiliac disease [1,4,5,9,10,16,18,21]. Less has been reported concerning the laparoscopic treatment of the infrarenal aortic aneurysm [6,7,11], for the obvious reason that laparoscopic treatment of the latter entity is much more demanding.…”

Intestinal retractor for transperitoneal laparoscopic aortoiliac reconstruction

“…The mean postoperative hospital stay was 6 days (range, [3][4][5][6][7][8][9][10][11][12][13], and six of the eight patients left the hospital on or before day 6.…”

Gasless videoendoscopic implantation of aortobifemoral vascular prostheses via transperitoneal or extraperitoneal approach in an animal model

“…Why did Dr. Bruns et al [1] employ the straight and 30°a ngular optic for dissection and a 50°angular optic for the anastomoses, seeing we believe that using the 50°angular optic demands a higher degree of laparoscopic coordinating capability? I also would be grateful to know how the ''specially configured retractor net'' was constructed, which apparently was used to retain the displaced intestine in the upper abdomen.…”

“…I read with great interest the article by Dr. Bruns et al [1] and congratulate the authors for having continued with the project of laparoscopic vascular surgery in the pelvic region that I had initiated at the same Department of Surgery at the University Hospital of Cologne back in 1992 [2][3][4][5].…”
