A tutorial education system for medical students was introduced at Kinki University in 1998. To evaluate the efficacy and to identify problems of the system, questionnaires were given to both students and tutors. Many students (approximately 80%) enjoyed the system and felt that tutorial lectures were effective. Many students believed that their selflearning time had increased and that they had developed the ability to think scientifically. However, they also thought that the material for tutorials was insufficient and that some tutors lacked teaching ability. Tutors thought that students had developed motivation (52%), problem-solving ability (58%), and debating skills (77%). Tutors also pointed out several problems, e.g., that some students had not developed self-leaning ability. Also, some tutors were poorly motivated. These findings suggest that we need to improve tutorial materials and the quality of tutors as well as fostering the self-learning ability of students.

A 63-year-old woman underwent coronary artery bypass grafting and mitral annuloplasty 4 years previously. She was readmitted owing to heart failure. Cardiac catheterization revealed worsened mitral regurgitation, although the internal thoracic artery (ITA) graft had good patency. Reoperation was performed by median resternotomy and continuous retrograde cardioplegia without clamping the ITA graft. The mitral valve had a perforation in the anterior leaflet, and was replaced by a 29mm Carbo-Medicus valve. The patient was discharged with transient myocardial ischemia. Although median resternotomy and continuous retrograde cardioplegia at reoperation provided on excellent view and myocardial protection, myocardial ischemia in the region perfused by the ITA graft may occur when the ITA graft cannot be clamped during continuous retrograde cardioplegia.

Introduction: Patients of end-stage heart failure often develop dyspnea. Although morphine is used for dyspnea, these patients are often inappropriate group for using morphine due to renal failure. Case: A seventy-year-old male with end-stage heart failure due to dilated cardiomyopathy developed dyspnea. We used continuous oxycodone infusion for dyspnea with small dose as an alternative to morphine due to renal failure. His dyspnea was relieved in dose-dependent without heart failure recovery. Conclusion: Oxycodone may be an alternative therapy for dyspnea with end-stage heart failure with renal failure.

OBJECTIVE: Uterine carcinosarcoma (UCS) is a rare type of high-grade endometrial cancer (EC) that has been understudied with population-based statistics due to its rarity. This study examined temporal trends in the proportion of UCS among women with EC. METHODS: This is a retrospective observational study examining The Surveillance, Epidemiology, and End Results program between 1973–2013. Primary EC cases were eligible for analysis, and a time-specific proportion of UCS was examined during the study period. RESULTS: UCS was seen in 11,000 (4.7%) women among 235,849 primary EC cases. Mean age at UCS diagnosis increased from 65.9 to 71.7 years between 1973–1989 and then decreased from 71.7 to 67.0 years between 1989–2013 (both, p < 0.001). Proportion of Black women significantly increased during the study period (11.9%–20.0%, p < 0.001), whereas the proportion of White women decreased from 86.0% to 60.5% between 1987–2013 (p < 0.001). There was a significant increase in the proportion of UCS among primary EC from 1.7% to 5.6% between 1973–2013 (p < 0.001). Among type II ECs (n=76,118), the proportion of UCS also increased significantly from 6.0% to 17.5% between 1973–2013 (p < 0.001). An increasing proportion of UCS was seen in both young and older women but the magnitude of interval increase was larger in the older age group between 1973–2013 ( < 60 years, from 1.3% to 3.3%. p < 0.001; and ≥60 years, from 2.6% to 7.0%, p < 0.001). CONCLUSION: Our study demonstrated that the proportion of UCS has significantly increased among EC, accounting for more than 5% in recent years.

OBJECTIVES: Intraoperative tumor manipulation and dissemination may possibly compromise survival of women with early-stage cervical cancer who undergo minimally-invasive radical hysterectomy (RH). The objective of the study was to examine survival related to minimally-invasive RH with a “no-look no-touch” technique for clinical stage IB1 cervical cancer. METHODS: This retrospective study compared patients who underwent total laparoscopic radical hysterectomy (TLRH) with no-look no-touch technique (n=80) to those who underwent an abdominal radical hysterectomy (ARH; n=83) for stage IB1 (≤4 cm) cervical cancer. TLRH with no-look no-touch technique incorporates 4 specific measures to prevent tumor spillage: 1) creation of a vaginal cuff, 2) avoidance of a uterine manipulator, 3) minimal handling of the uterine cervix, and 4) bagging of the specimen. RESULTS: Surgical outcomes of TLRH were significantly superior to ARH for operative time (294 vs. 376 minutes), estimated blood loss (185 vs. 500 mL), and length of hospital stay (14 vs. 18 days) (all, p < 0.001). Oncologic outcomes were similar between the 2 groups, including disease-free survival (DFS) (p=0.591) and overall survival (p=0.188). When stratified by tumor size (<2 vs. ≥2 cm), DFS was similar between the 2 groups (p=0.897 and p=0.602, respectively). The loco-regional recurrence rate following TLRH was similar to the rate after ARH (6.3% vs. 9.6%, p=0.566). Multiple-pelvic recurrence was observed in only 1 patient in the TLRH group. CONCLUSION: Our study suggests that the no-look no-touch technique may be a useful surgical procedure to reduce recurrence risk via preventing intraoperative tumor spillage during TLRH for early-stage cervical cancer.

The Laparoscopic Approach to Cervical Cancer (LACC) trial demonstrated that minimally invasive radical hysterectomy was inferior to the open approach [1]; this unexpected result could be attributed to the spillage of cancer cells [2]. Following the LACC trial, laparoscopic radical hysterectomy without an intrauterine manipulator upon completion of a vaginal cuff closure became the new standard treatment method [3]. However, the lack of intrauterine manipulator results in poor visualization and inadequate paracervical tissue resection. This study describes the no-look no-touch technique to address this difficulty. The core procedures in our no-look, no-touch laparoscopic radical hysterectomy are: (Step 1) Creation and closure of a vaginal cuff; (Step 2) Manipulation of the uterus without an intra-uterine manipulator; and (Step 3) Exposure of the paracervical tissues by the suspension technique. The patient eligibility for our procedure is as follows: 1) previously untreated cervical cancer (those who underwent diagnostic conization could be included); 2) clinical stage IA2, IB1, IB2, and IIA1 based on the 2018 International Federation of Gynecology and Obstetrics staging system; 3) histologically confirmed cervical cancer, including squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma. The important indication for this procedure is in cases where the tumor is less than 4 cm in diameter. We previously reported that our no-look no-touch technique enables smooth performance of laparoscopic radical hysterectomy without worsening oncologic outcomes [4]. According to a recent systematic review and meta-analysis [5], minimally invasive radical hysterectomy with vaginal cuff closure is a safe treatment option; however, it involves a steep learning curve, which has impeded its increased application. This video will hopefully make minimally invasive radical hysterectomy with protective maneuvers against cancer cell spillage more accessible. Based on our experiences, we propose that our transvaginal cervical tumor-concealing no-look no-touch technique will mitigate the risk of surgical spill of tumor cells during minimally invasive radical hysterectomy. The informed consent for use of this video was taken from the patient.
