Many cardiovascular surgeons are well aware of the importance of non-technical skills but don't know what behaviors with high quality non-technical skills are in the operating room. The Non-Technical Skills for Surgeons (NOTSS) system was developed to be used as a debriefing tool for supervisors to assess the non-technical skills of trainee surgeons and provide feedback immediately after surgery. The NOTSS system has the four categories containing three elements respectively, with "good behavior" and "bad behavior" indicated for each element. The purpose of this column is to introduce the NOTSS and to provide an opportunity to think about how cardiovascular surgeons should behave in the operating room. Jpn. J. Cardiovasc.

This column is a roundtable discussion featuring three U40 members who have been extensively involved in the organization and planning of hands-on training, along with Mr. Park, the CEO of EBM Corporation. The four participants discuss hands-on training in the field of cardiovascular surgery. Drawing on their experiences with programs such as the Cardiovascular Surgery Summer School, Basic Lecture Course (BLC), Online BLC, Advanced Lecture Course (ALC), and the coronary anastomosis competition “Challengers' Live Demonstrations,” they explore the essence of hands-on training, current challenges, and future prospects in this field.

Along with clinical practice and education, research is among the most important activities for medical doctors. The same is true in cardiovascular surgery: Young cardiovascular surgeons are expected to improve their surgical techniques and prioritize their clinical practice. However, their perspective on the role of research in their field of expertise is unknown. Therefore, we conducted a survey of and discussion with young cardiovascular surgeons to clarify their thoughts and concerns about performing research. Here we review and report the survey and discussion results.

Background/Aims:
We retrospectively analyzed Crohn’s disease (CD) patients with small intestinal strictures who underwent single-balloon enteroscopy (SBE) to ascertain whether prototype SBEs with a passive bending mechanism and high force transmission insertion tube had better insertability in the small intestine than a conventional SBE.
Methods:
Among 253 CD patients who underwent SBE, we identified 94 CD patients who had undergone attempted endoscopic balloon dilatation (EBD) for small intestinal stenosis for inclusion in this study. We analyzed whether the type of scope used for their initial procedure affected the cumulative surgery-free rate. For the insertability analysis, patients who underwent SBE at least twice were divided into 3 groups according to the type of scope used: conventional SBE only, prototype SBE only, and both conventional and prototype SBEs. For each group, depth of insertion, procedure time, and number of EBDs were compared in the same patient at different time points.
Results:
The success rate of EBD was 88.3%. The 5- and 10-year cumulative surgery-free rate was 75.7% and 72.8%, respectively. Cox regression analysis indicated that the factors contributing to surgery were long stricture (≥2 cm), EBD failure, and elevated Crohn’s Disease Activity Index, but not the type of scope used for EBD. The prototype SBEs significantly improved the depth of insertion (P=0.03, Wilcoxon’s signed-rank test).
Conclusions
In CD patients with small intestinal stenosis, the prototype SBEs with a passive bending mechanism and high force transmission insertion tube did not improve long-term EBD outcome but did improve deep insertability. (Clinical Trial Registration No. UMIN000037102)

Purpose: The objective of this study was to investigate whether body fat rate (BFR) and triceps skinfold thickness (TSF) are associated with estimated fentanyl absorption in patients treated with the fentanyl transdermal matrix patch for moderate to severe cancer pain, by measuring the residual content of fentanyl in used matrix patches. Methods: Adult Japanese inpatients experiencing chronic cancer-related pain and receiving treatment for the first time with a transdermal fentanyl matrix patch (Durotep®MT patch) were included in the present study. During the initial application period, BFR was measured using a body fat scale, and TSF was measured by an experienced nurse with an adipometer. One patch was collected from each patient. The residual fentanyl content in used matrix patch was determined by high-performance liquid chromatography. The transdermal fentanyl delivery efficiency was estimated based on the fentanyl content of the used matrix patches. Results: Fifteen adult patients (5 males and 10 females) were included in this study. Nine patches with a release rate of 12.5μg/h and 6 patches with a release rate of 25μg/h were collected. The application site was the chest or upper arm. BFR and TSF both showed a significant positive correlation with delivery efficiency. Conclusion: In malnourished or low-body fat patients receiving DMP, pain intensity should be more carefully monitored, and fentanyl dose adjustment may be required. Additional parameters, such as nutritional status including body fat change, the degree of dry skin, and plasma fentanyl concentration, also require detailed evaluation.

Objectives:
As the population ages worldwide, including in Japan, there is a growing expectation for older adults to remain active participants in society. The act of sharing one’s experiences and knowledge with younger generations through social engagement not onlyenriches the lives of older individuals, but also holds significant value for our society. In thisstudy, we examined both positive and negative perceptions of older adults and investigated the correlation between these perceptions and generativity among older citizens. Additionally, we evaluated the impact of life satisfaction on these factors.
Methods:
We conducted a survey of 100 older adults in Japan (mean age, 71.68 years) and utilized multiple regression analyses, using positive and negative perceptions of older adults, life satisfaction, and demographic factors as independent variables. The sub-categories of generativity—namely, generative action, concern, and accomplishment—were used as dependent variables.
Results:
Participants who held a more positive perception of older adults demonstrated a higher level of generative actions and concerns. Additionally, participants who reported higher levels of life satisfaction also exhibited more generative actions, concerns, and accomplishments. Conversely, those who held a more negative perception of older adults were found to have higher levels of generative actions.
Conclusion
Enhancing positive perceptions of older adults among them can boost the subcategories of generativity. This study, which was conducted from an exploratory perspective, has several limitations, including a potential sampling bias. A more comprehensive examination of the relationship between perceptions of older adults and generativity is anticipated in future research.

BACKGROUND/AIMS: There are few prospective studies on cold forceps polypectomy (CFP) using jumbo cup forceps. Therefore, we examined patients with diminutive polyps (5 mm or smaller) treated with CFP using jumbo cup forceps to achieve an adenoma-free colon and also assessed the safety of the procedure and the recurrence rate of missed or residual polyp after CFP by performing follow-up colonoscopy 1 year later. METHODS: We included patients with up to 5 adenomas removed at initial colonoscopy and analyzed data from a total of 361 patients with 573 adenomas. One-year follow-up colonoscopy was performed in 165 patients, at which 251 lesions were confirmed. RESULTS: The one-bite resection rate with CFP was highest for lesions 3 mm or smaller and decreased significantly with increasing lesion size. Post-procedural hemorrhage was observed in 1 of 573 lesions (0.17%). No perforation was noted. The definite recurrence rate was 0.8% (2/251 lesions). The probable recurrence rate, which was defined as recurrence in the same colorectal segment, was 17%. Adenoma-free colon was achieved in 55% of patients at initial resection. Multivariate analysis revealed that achievement of an adenoma-free colon was significantly associated with number of adenomas and years of endoscopic experience. CONCLUSIONS: CFP using jumbo biopsy forceps was safe and showed a high one-bite resection rate for diminutive lesions of 3 mm or smaller. The low definite recurrence rate confirms the reliability of CFP using jumbo biopsy forceps. Number of adenomas and years of endoscopic experience were key factors in achieving an adenoma-free colon.
