Background Secondary aortoenteric fistula is a fatal cause of gastrointestinal bleeding after aortic reconstructive surgery with a prosthesis. In most cases, the proximal suture line is involved. We herein report a rare case in which the fistula formed between the suture line of inferior mesenteric artery reimplantation and the jejunum. Case Presentation An 82‐year‐old man was transferred to our hospital due to hematemesis with severe hypovolemic shock. Although he fell into cardiopulmonary arrest, immediate resuscitation achieved return of spontaneous circulation. As his surgical history of aortic reconstruction and computed tomography findings suggested potential secondary aortoenteric fistula, emergency surgery was carried out. The anastomosis between the inferior mesenteric artery and aortic graft was communicating with the jejunum. Partial jejunal resection was undertaken, and the aortic graft was replaced. Conclusion The anastomosis between the inferior mesenteric artery and aortic graft in the previous aortic replacement can become the site of secondary aortoenteric fistula.

Aim The Bleeding Control Basic (BCon) course was developed by the American College of Surgeons to teach laypeople and health‐care providers (HCPs) how to stop life‐threatening bleeding. The first BCon course in Japan was held for HCPs in July 2018. Our study aimed to evaluate the utility of the course, the satisfaction and confidence level of the HCPs that participated, and their experience with using vascular tourniquets. Method The BCon participants were asked to complete a survey after the BCon courses from December 2018 to December 2019. These participants included different types of HCPs (physicians, nurses, and emergency medical technicians). After the course, the participants were asked to evaluate: (i) the perceived utility of the course, (ii) their satisfaction with the course, (iii) their confidence in the techniques that they learned in the course, (iv) their experience of using tourniquets in eight specific areas using a 10‐point Likert scale. Results A total of 163 HCPs, including 108 physicians, 27 nurses, and 28 emergency medical technicians completed the BCon course. The respondents rated the course highly, showing an average value of approximately 9 for each item for perceived utility, satisfaction, confidence, and experience in using tourniquets. In particular, nurses rated the overall activity more highly than physicians (P
