Retroperitoneal versus Transperitoneal Approach for Repair of Abdominal Aortic Aneurysms / 日本心臓血管外科学会雑誌

ABSTRACT

Between 1988 and 1991, 231 patients underwent surgical repair for abdominal aortic aneurysm. Among them 132 patients underwent isolated Y graft replacement electively. They were divided into two groups, according to the operative procedure; transperitoneal approach (<i>n</i>=51) and retroperitoneal approach (<i>n</i>=81), and the surgical results were compared retrospectively. There was no significant difference in operative time, amount of operative bleeding, operative transfusion, total transfusion, autotransfusion, duration of intubation, total use of analgesia or length of postoperative stay in the two groups. The amount of fluid drained from the nasogastric tube was significantly greater in the transperitoneal group. The initiation of drinking and eating were both significantly prolonged in the transperitoneal group. The transperitoneal approach is indicated for cases with thoracic or thoracoabdominal aneurysm which may be operated on in the future, cases of bilateral common iliac aneurysms and cases with heart disease. Otherwise it is preferable to select the retroperitoneal approach as the first choice for elective surgical treatment of abdominal aortic aneurysm, because the retroperitoneal approach is superior in terms of the recovery of gastro-intestinal movement.
