Adenocarcinoma is a common histological type of ulcerative colitis-associated cancer (UCAC), whereas neuroendocrine carcinoma (NEC) is extremely rare. UCAC is generally diagnosed at an advanced stage, even with regular surveillance colonoscopy. A 41-year-old man with a 17-year history of UC began receiving surveillance colonoscopy at the age of 37 years; 2 years later, dysplasia was detected in the sigmoid colon, and he underwent colonoscopy every 3 to 6 months. Approximately 1.5 years thereafter, a flat adenocarcinoma lesion occurred in the rectum. Flat lesions with high-grade dysplasia were found in the sigmoid colon and surrounding area. The patient underwent laparoscopic total proctocolectomy and ileal pouch-anal anastomosis with ileostomy. Adenocarcinoma was diagnosed in the sigmoid colon and NEC in the rectum. One year postoperation, recurrence or metastasis was not evident. Regular surveillance colonoscopy is important in patients with long-term UC. A histological examination of UCAC might demonstrate NEC.

In Western countries, the gold-standard therapeutic strategy for rectal cancer is preoperative chemoradiotherapy (CRT) following total mesorectal excision (TME), without lateral lymph node dissection (LLND). However, preoperative CRT has recently been reported to be insufficient to control lateral lymph node recurrence in cases of enlarged lateral lymph nodes before CRT, and LLND is considered necessary in such cases. We performed a literature review on aspects of pelvic anatomy associated with rectal surgery and LLND, and then combined this information with our experience and knowledge of pelvic anatomy. In this review, drawing upon research using a 3-dimensional anatomical model and actual operative views, we aimed to clarify the essential anatomy for LLND. The LLND procedure was developed in Asian countries and can now be safely performed in terms of functional preservation. Nonetheless, the longer operative time, hemorrhage, and higher complication rates with TME accompanied by LLND than with TME alone indicate that LLND is still a challenging procedure. Laparoscopic or robotic LLND has been shown to be useful and is widely performed; however, without a sufficient understanding of anatomical landmarks, misrecognition of vessels and nerves often occurs. To perform safe and accurate LLND, understanding the landmarks of LLND is essential.

The U-40 generation of surgeons are practicing through trial and error, and form various careers. At the 51st Annual Meeting of the Japanese Society of Cardiovascular Surgery, U-40 Special Project, we looked back on the U-40 generation and more senior doctors to see what kind of future visions, problems and careers they have had. We conducted a questionnaire for the purpose of visualizing the future prospects of the U-40 generation. In this article, we report the results.

Purpose: This study aimed to report on the multidisciplinary web conferences for patients with heart failure to strengthen medical collaboration and provide seamless support. Method: We described and analyzed the web conferences by retrospectively collecting data on the conferences. Result: Main subjects of the conferences were those who lived alone and had inadequate nursing care, and those to whom the intervention of multidisciplinary professionals needed to be strengthened to prevent readmission. Using web conferencing tools, we shared issues and solutions for discharge with considering the anonymity of the patient’s personal information. The conferences were held once weekly for 30 minutes when the patients were in the stages of preliminary discharge planning. Participating physicians and healthcare professionals included cardiologists, nurses, pharmacists, physical therapists, nutritionists, palliative care physicians, and home doctors. The cardiology staff used a multifaceted checklist to clarify issues while sharing the patient’s condition and treatment plan. The palliative care physicians made suggestions about value-based treatment plans and decision support, and the home doctor made suggestions about home services, drug adjustment, and lifestyle guidance necessary to prevent readmission. Discussion: Further improvement in the web conferences and evaluation on the effect of the conferences are needed.

Methods: Nineteen volunteers (16 men, three women) lifted a 60-kg doll from a seated position to a standing position. The first transfer was performed without the HAL for Care Support, and the second was performed with the HAL for Care Support assistive robot. We evaluated transfer performance, the visual analog scale (VAS) score for lumbar fatigue, and electromyogram analyses of the trunk and hip. Results: Four participants (two men, two women) succeeded with the HAL for Care Support even though they were unable to perform the task without it. The mean lumbar fatigue VAS score for all participants without the HAL for Care Support was 62 mm, while that with it was 43 mm. With lumbar assistance from the HAL for Care Support, subjective lumbar fatigue during the transfer decreased significantly. A power analysis indicated adequate statistical power to detect a difference in the VAS score for lumbar fatigue (0.99). The activity of the left gluteus maximus alone increased significantly during transfers with the HAL for Care Support. No adverse events occurred during use of the HAL for Care Support for transfers. Conclusions The HAL for Care Support was able to reduce lumbar load in a simulated patient transfer.

Objectives : We sought to present data relative to valvular heart surgeries from the Japan Cardiovascular Surgery Database in 2017 and 2018 to show current status and trend in Japan. Methods : We extracted data relative to cardiac valve surgeries performed in 2017 and 2018 from the Japan Cardiovascular Surgery Database. We obtained total number of aortic valve replacement procedures and showed trend for these 6 years from 2013 to 2018. The operative mortality rates were shown for representative valve procedures stratified by age group with the aim of showing a bench mark of Japan. Data regarding minimally invasive procedures and transcatheter aortic valve implantation which the Japan Cardiovascular Surgery Database can provide were also presented. Results : Despite dramatic increase of number of transcatheter aortic valve implantation in 2017 and 2018 compared to in 2015 and 2016, surgical aortic valve replacement also increased from 26,054 to 28,202. Regarding the operative mortality of first time valve procedures, it was 1.8% in isolated aortic valve replacement, 0.9% in isolated mitral valve repair, 8.2% in mitral valve replacement with biological prostheses, and 4.6% with mechanical prostheses. For first time valve procedures with concomitant coronary artery bypass, the operative mortality was 5.2% in aortic valve replacement, 4.9% in mitral valve repair. Regarding prosthetic valve selection, 72.6% of patients had biological prosthesis for aortic valve replacement procedures in their 60's, showing trend of increasing percentages of biological valve choice. Regarding minimally invasive procedure, 31.8% of first time isolated mitral valve plasty were performed via right thoracotomy. Though patients who underwent surgery via right thoracotomy had better clinical outcomes, it was also apparent that the patients who underwent surgery via right thoracotomy had lower operative risk profile. Aortic clamp time and cardiopulmonary bypass time were longer in the right thoracotomy patients. 6.3% of the patients who had isolated aortic valve replacement underwent surgery via right thoracotomy. The right thoracotomy aortic valve replacement patients had better clinical outcomes and had more percentage of lower risk profile. The overall mortality of transcatheter aortic valve implantation and surgical aortic valve replacement were 1.5% and 1.8%, respectively. Conclusion : We reported data related to heart valve surgery in 2017 and 2018 from the Japan Cardiovascular Surgery Database.

Objectives : Data of valvular heart surgeries from the Japan Cardiovascular Surgery Database in 2015 and 2016 were analyzed to demonstrate the associated mortality and morbidity rates and choice of surgical procedures. Methods : We used the Japan Cardiovascular Surgery Database to extract data of cardiac valve replacement procedures performed in 2015 and 2016. The cases were further evaluated depending upon the type of procedure, and prosthesis used at each site. The rate of bio-prosthesis usage was derived for each valve position and age groups. The rates of operative mortality and morbidity were calculated for each valve position and type of procedures. Results : In total, 26,054 aortic valve replacements were performed in 2015 and 2016, showing a slight increase in number since the last report(2013-2014). A total of 3,305 transcatheter aortic valve replacements, 5,652 mitral valve replacements, and 12,024 mitral valve repair procedures were performed. The rate of bio-prosthesis usage in aortic valve replacement was 96.5%, 92.7% and 63.5% for patients in their 80s, 70s and 60s, respectively, demonstrating an increase in usage since 2013-2014. Mechanical valves were preferred in patients on chronic hemodialysis. The mortality rates of aortic valve replacement, mitral valve replacement, mitral valve repair, and tricuspid valve replacement procedures were 4.1%, 7.1%, 2.2%, and 10.5%, respectively. Conclusion : We evaluated recent trends in valvular heart surgery in Japan with respect to the type of procedure and prosthesis preferred and the postoperative outcomes. We found that bio-prosthesis usage was the most common.

From the start, World Health Organization has proposed that palliative medicine is applicable early in the course of illness. However, regrettably, palliative care has been usually provided to patients in the advanced cancer stage, as a terminal care. Recently, palliative medicine begins at the time-point when patients are diagnosed with cancer. In response to change in clinical settings of palliative medicine, cancer pain management has also changed. Considering long-term cancer treatment periods and increasing numbers of cancer survivors, cancer pain management should be recommended based on not only non-opioid pharmacotherapy but also the exercise/rehabilitation medicine and the cognitive-behavioral therapy. Especially, the exercise/rehabilitation medicine can provide beneficial effects on both pain management and cancer treatment itself: Sarcopenia is closely associated with poor prognosis of cancer and debilitating complications of chemotherapy. Further, non-sarcopenia patients can maintain their quality of life higher and show less fatigue during cancer treatment periods. To accomplish such favorable effects for cancer patients and cancer survivors, cancer pain should be managed adequately.
