Ischemic colitis is a serious complication of abdominal aortic surgery. Patients with bilateral internal iliac aneurysm have a high risk of ischemic colitis after operation. A 72-year-old man had infrarenal abdominal aneurysm, bilateral common and internal iliac aneurysm and an occluded right internal iliac artery. We examined the flow of the superior rectal artery during operation by transanal Doppler, and intramucosal pH of the sigmoid colon by a tonometer after operation. The flow of the superior rectal artery did not change after clamping of the left common iliac artery, clamp of the infrarenal aorta. He underwent uneventful abdominal aortic aneurysmectomy, Y-grafting and exclusion of bilateral internal iliac aneurysms. The intramucosal pH of the sigmoid colon returned to the normal range 25h after surgery. He had no complications after surgery. Transanal Doppler examination was essential for the successful prevention of postoperative colonic ischemia, and intestinal intramural pH by tonometry was an early reliable marker of the absence of ischemic colitis.

Medical recording is an important learning issue for the clerkship curriculum. Privacy laws require that medical students' access to patient information be managed by faculty members. The Workshop of Medical Education was convened at the Medical Education Development Center, Gifu University, in October 2004 to discuss the management of electronic medical recording systems for clinical clerkships. The purpose of this article is to propose management guidelines and rules for electronic medical recording systems for clinical clerkships in Japan.

Early clinical exposure has been implemented worldwide as an effective method of medical education. The duration of early clinical exposure is 1 year in some universities in Western countries. In Japan, however, early clinical exposure occurs most often through health and welfare services, and its duration varies. One-year early clinical exposure and reflection upon it were implemented for first-year students at Mie University School of Medicine in 2006 to motivate them and to teach them about professionalism. The effectiveness of this program was evaluated with a questionnaire, a daily log, and a portfolio.1) The questionnaire survey revealed that students considered the program extremely valuable. They had learned much about communication skills, the relationship between medicine and society, patients' families, and professionalism.2) An analysis of the daily logs clearly showed that students were unsure and hesitant at the start of the program. However, they gradually became accustomed to participating in this program and began to learn earnestly.3) Qualitative analysis of the portfolios revealed that students considered 10 items important in the practice of medicine, including communication skills, responsibility, the value of being a physician, professionalism, and the motivation to study medicine.4) In their final reports, the students described the expected behaviors of physicians they should seek to perform, by learning medical ethics or through professionalism.5) In conclusion, 1-year early clinical exposure is a more effective method than short-term or intermittent exposure for medical students because of its uniqueness and the maintenance of motivation.

Between January 1991 and December 1998, we performed two successful procedures to repair abdominal aortic aneurysm with primary aortoenteric fistula. We had 197 surgical repair proceduers of aortic aneurysm during the same period. Incidence of primary aortoenteric fistula in abdominal aortic aneurysm was 1% in our institute. We performed primary closure of the fistula and removal of the possibily infected aneurysmal wall followed by anatomical grafting. We utilized omental wrapping for prophylaxis of potential graft infection. We achieved excellent surgical results in both patients by this approach.
