Objective: We assessed the effectiveness and appropriateness of our original off-the-job training (Off JT) system using data acquired from recruited medical students and doctors.Materials and Methods: We presented our original homebuilt Off JT system, which is simple and inexpensive. In our unique system, we performed anastomosis at the bottom of a plastic pot, which mimics the actual open surgical procedure at a deep site. There were four evaluation points: (A) operating time, (B) performance of anastomosis by semi-automatically analyzing the image with the coefficient of variation (standard deviation/length) of the “bite” and the “pitch,” (C) scoring of the total surgical skill evaluated by the trainers according to the Operative Performance Rating System (OPRS), and (D) the relationship of these three factors (A, B, and C).Results: The procedural time and coefficient of variation of the bite and pitch decreased and the OPRS score increased after training. There was a strong correlation between procedural time, anastomotic performance, and OPRS score.Conclusion: The effectiveness of our original homebuilt system was shown by reduced procedural time, improved anastomotic quality, and increased OPRS score.

Here we describe a hybrid procedure, that is, a combination of open isolation and coil embolization, to treat a saccular middle colic artery aneurysm deep behind the pancreas. The middle colic artery provided the collateral blood flow necessary to bypass a chronic segmental aortic occlusion. For preservation of the collateral vessels, we surgically excluded and bypassed the aneurysm and then performed endovascular embolization of the pancreaticoduodenal arteries flowing into the aneurysm, resulting in complete isolation of the aneurysm without jeopardizing blood flow. This hybrid procedure for visceral artery aneurysms can be effective when the collateral vessels need to be preserved.
