Reports laparoscopic deroofing of liver cysts have drawn our attention recently. A laparoscopic approach has advantages as minimal access surgery, but has the possibility of causing complications by hemorrhage and bile leakage. In this paper, we described three surgical cases of symptomatic giant liver cysts. In case 1, hemorrhage occurred when we resected the cyst wall by electrocautery with the aid of a laparoscope. Therefore, in case 2, we resected the cyst wall with an endoscopic stapling device (ENDO GIA) for complete hemostasis and control of bile duct, because the peritoneal surface of the cyst was overlaid by thin parenchymal tissue. In case 3, we resected the cyst wall with laparoscopic coagulating shears (LCS), because the peritoneal surface of the cyst was mainly extrahepatic. This device reduces the risk of hemorrhage and damage to the liver. These patients were asymptomatic after operation and developed no signs of recurrence. We suggest that the laparoscopic deroofing of liver cysts with these devices, a simple, safe procedure, may become a primary method of treating symptomatic liver cysts.

　The higher level postgraduate education hospitals are required to have a system with well-developed programs, instruction, and supervision of doctors in clinical training. The Social Medical Corporation Kojunkai Daido Hospital has been maintaining efforts to be a clinical training hospital of excellence.

　In order to nurture supervisory doctors, the first workshop for supervisory doctors in clinical training was held at Daido Hospital on February 22nd and 23rd, 2014. With consciousness reform in mind, interprofessional relations between the many types of medical professional were established.

　Daido Hospital was evaluated by the Japan Council for Evaluation of Postgraduate Clinical Training on December 12th, 2014. It was an opportunity to recognize the need for further improvement as a clinical training hospital.

　On March 7th, 2015 the Objective Structured Clinical Examination for the second year of training doctors in Daido Hospital was held. Clinical training guidance doctors, Nurses, and paramedics learned the skills necessary for the methods and the evaluation in clinical teaching and evaluation.

　Daido Hospital continues making efforts by conducting a review of the clinical training based on the evaluation of the clinical ability of residents, the ability for education and the clinical skill of teaching doctors, and the training environment.

　Social Medical Corporation Kojunkai Daido Hospital is aiming to be the best training hospital. By enhancing seminars in the hospital, we commenced a postdoctoral training program for medical instructors in February 2014 and November 2015. Since we received an accreditation for the clinical training program in 2014, we created an OSCE program on our own for trainees in August 2015 and June 2016. We also collaborated with the University of Nagoya for the OSCE program and held seminars in August 2015 and June 2016. We introduced the EPOC system for the evaluation of trainees in 2014, and Cybouze® for the constructive evaluation of and sharing of information on trainees in April 2016. Our residents obtained high scores for in the examination to evaluate knowledge of trainees held in February 2016, which shows the high quality of our educational program, established by the endless efforts of the educational committee and instructors.
