Laparoscopic Extraperitoneal Approach for Lateral Pelvic Node Dissection in Rectal Cancer: Techniques and Short-Term Outcomes.

BACKGROUND: Lateral pelvic lymph node dissection has been performed selectively in rectal cancer cases; however, it involves highly skilled techniques because of the complex adjacent anatomical structures. MATERIALS AND METHODS: Laparoscopic EP-LPND was performed in Korea University Anam Hospital from June 2018, and short-term surgical outcomes were analyzed from June to December 2018. Among the patients with histologically diagnosed rectal adenocarcinoma, patients who were suspected Lateral pelvic lymph node metastasis at magnetic resonance imaging were selected for this procedure. RESULTS: Seven patients underwent laparoscopic extraperitoneal approach for lateral pelvic lymph node dissection in the study period. The mean number of retrieved lymph node was 4.57, and metastatic lymph nodes were identified in 3 patients (42.8%). All of the lymph nodes with suspected metastasis preoperatively were removed in postoperative images. There was no immediate postoperative complication beyond the moderate grade associated with lateral pelvic lymph node dissection. The median follow-up was 9 months, and there were no local recurrence nor complications related to sexual and voiding functions. CONCLUSIONS: The laparoscopic extraperitoneal approach might be an efficient way to perform lateral pelvic lymph node dissection using the same principles as the conventional method without violation of the peritoneum.

Validation of a Modified Version of Interpersonal Reactivity Index for Medical Students Using Rasch Analysis.

Construct: Empathy has been accepted to interweave both cognitive aspects (the ability to put oneself in another person's place), and affective (or emotional) aspects, indicating an emotional reaction or response to another person's emotional state. Literature supports the positive influences of empathy on doctor-patient relationship, patient satisfaction, and positive clinical outcomes. Background: Many studies have dealt with the development of empathy measurement tools for physicians and medical students. A frequently used empathy measuring instrument for medical students is the "Interpersonal Reactivity Index" (IRI) which was designed to measure the multi-dimensional aspects of empathy in the general adult population. Most previous literature which validated IRI for medical students has used factor analysis, whilst studies applying Rasch models have been limited. Our study aimed to investigate the psychometric properties of a modified version of IRI for medical students using Rasch analysis. Approach: Medical students (1,293) from 15 medical schools in South Korea participated in an online questionnaire consisting of 28 items of the Korean translated version of IRI. We applied exploratory factor analysis (EFA) using polychoric correlation matrix to determine the optimal number of factors followed by Rasch analysis and McDonald's Omega calculation. Findings: The adapted IRI-MS (IRI for medical students) consisted of 17 items in four dimensions: empathic concern (5), fictitious situation (4), perspective taking (4), and personal distress (4). The overall fit of IRI-MS revealed an acceptable goodness-of-fit for all 17 items and a positive point measure correlation for all items. Reliability indices from the Rasch modeling and McDonald's Omega values of all four dimensions were satisfactory for research. We found the Wright-Andrich maps and category probability curves of the IRI's four dimensions to be less than optimal in measuring empathy levels with adequate precision. Conclusions: Rasch analysis of IRI-MS fell short from being able to prove satisfactory validity in measuring the multidimensional nature of empathy in medical students. However, our study applying Rasch analysis may serve as groundwork for future studies, to further develop from the shortcomings of our findings.Supplemental data for this article are available online at at www.tandfonline.com/htlm .

A Minimally Invasive Pelvic Multivisceral Resection Approach for Locally Advanced Primary Colorectal Cancers: A Single-Institution Experience.

Background: The role of minimally invasive surgery (MIS) in locally advanced colorectal cancers (CRCs) suspected of direct invasion to adjacent organs or structures remains controversial. The aim of this study is to verify the safety and feasibility of minimally invasive multivisceral resection (MVR) surgery for locally advanced CRCs compared with conventional open surgery. Materials and Methods: Prospectively collected data from patients who underwent MVR for locally advanced CRCs from 2007 to 2017 were retrospectively reviewed. Patients with preoperative clinically suspected T4b stage cancers were enrolled in the study. Results: There were 30 and 19 patients in the MIS and open surgery groups, respectively. Seven patients in the MIS group required conversion, and the most common reason for conversion was ureter and bladder invasion. Tumor sizes were significantly larger in the open group (5.46 cm versus 7.48 cm, P = .010), whereas the MIS group included more patients with rectal cancers (56.7% versus 21%, P = .021). No differences were observed between the two groups in terms of operation time, estimated blood loss, and postoperative hospital stay. Curative (R0) resection was achieved in all patients, and the median follow-up period was 23 months. The 3-year overall survival in the MIS group was 73.6% and 77.9% in the open group (P = .445), and the 3-year total disease-free survival (DFS) was 59.2% and 51.4%, respectively (P = .695). Three-year local DFS was 83.3% for the MIS group, and 51.4% for the open group (P = .120). Conclusion: MIS for primary T4b CRCs without urinary tract invasion is safe and feasible.

The relationship between medical students' empathy and burnout levels by gender and study years.

OBJECTIVE: To investigate the multifaceted factors affecting empathy in medical students. METHODS: 1293 medical students from 15 South Korean medical schools participated in an online survey. Affective empathy was measured with the 'empathy concern' and 'personal distress' dimensions from the Interpersonal Reactivity Index for Medical Students (IRI-MS). Cognitive empathy was assessed with IRI-MS' 'perspective taking' and Jefferson Scales for Physician Empathy for Student (JSPE-S). Maslach Burnout Inventory for Medical Students (MBI-MS) assessed the burnout levels of the participants. RESULTS: A significant gender difference in affective and cognitive empathy was found using JSPE-S. Different patterns were seen in the empathy dimensions between the study years and genders. Burnout scores showed no gender differences, while exhaustion and cynicism increased, and academic efficacy decreased with seniority. Academic efficacy was a consistently influential factor for both affective and cognitive empathy in both genders, all study years and the three domains of burnout. CONCLUSION: Academic efficacy was a significant factor influencing both affective and cognitive empathy. PRACTICAL IMPLICATIONS: The comprehensive nature of empathy in medical students may be better investigated by applying multi-dimensional empathy measurement tools and by analyzing multiple factors such as gender, study year and burnout.

A scoping review on adaptations of clinical education for medical students during COVID-19.

Rapid advances in clinical education in response to the COVID-19 pandemic are taking place globally. This scoping review updated the educational strategies which could be applied by clinical educators in their practice to effectively maintain clinical attachment programs for medical students amidst public health crises. Almost all elements of clinical teaching were deliverable, whether it was online, onsite, virtual or blended, their educational effectiveness should be further examined. Increase in the number of telemedicine related publications were remarkable, and they could serve as a scalable model for future educational programs to be incorporated into the medical student curricula.

A Preliminary Study on Uncovering Medical Students' Unprofessional Behaviors from YouTube Videos.

Creation of guidelines and education on digital professionalism have been sluggish despite the ever-increasing use of social media by digitally native medical students, who are at risk of blurring the line between their professional and personal lives online. A qualitative thematic analysis was applied on 79 videos extracted from 70,154 YouTube videos uploaded by Korean medical students between March and April 2020. We found 20% contained at least one concerning behavior themed under 'failure to engage,' 'disrespectful behaviors,' or 'poor self-awareness.' Professional lapses identified were classified into seriousness levels. Mostly were "controversial' or 'concerning' but some 'highly concerning' contents were also found. This is the first study on digital professionalism behavior on medical students' YouTube videos. The potential negative impact on the medical profession of the easily accessible public online videos cannot be ignored and thus we suggest the need for them to be taken more seriously.

How the coronavirus disease 2019 pandemic changed medical education and deans' perspectives in Korean medical schools.

PURPOSE: This study explored how the Korean Medical Colleges responded to the coronavirus disease 2019 (COVID-19) pandemic and the medical deans' perspectives on what and how these adaptions influence the present and the future of medical education. METHODS: An email survey combining short and open-ended questions was distributed to all 40 Korean school deans in May 2020. Thirty-seven deans out of 40 medical schools in Korea (92.5%) participated. RESULTS: Most lectures moved online but students' assessments were delayed and later held onsite. Clinical rotations continued except for an average of 3-week suspension during the first COVID-19 wave. The deans' remarks on the positive influences far outweighed the negative impact of COVID-19 on medical education. Although technological adaptations caused initial hardship, the experience gained through the use of various online learning systems led to attitudinal changes on the importance of adopting new technology and a tailored and student centric curriculum in medical education. CONCLUSION: The deans' perspective changes has shown the possibility of the deans' generation aligning more closely with the current Generation Z medical students. They projected further innovations in teaching and learning methods, especially applying flipped learning and highlighted the need to invest in faculty development so medical educators can be equipped and competent in diverse ICT (information and communications technology) learning platforms. Also, the need for advance preparations in medical education for future similar public health crises were stressed. Unprecedented changes brought by COVID-19 positively impacted Korean medical education in parts and the Korean deans envisioned further innovations using the experiences gained during this crisis.

A survey investigating the current situation of the international visiting scholar program at the department of surgery in Korea.

PURPOSE: The number of international visiting scholars has been on the increase in Korea and we aim to investigate the program's current situation. METHODS: This cross-sectional study is based on an online survey questionnaire responded by international visiting scholars in surgical departments of 8 Korean hospitals between 2014 and 2018 about their experiences and satisfaction with the visiting scholar program. RESULTS: A total of 1,496 international scholars from 80 countries visited various surgical departments in 8 Korean hospitals between 2014 and 2018. The numbers have been on the increase over the years. Out of 355 visiting scholars in 2018, 71 replied to the online survey, of whom 52 were male and 19 female, and mostly in their 30s and 40s. Information about the program was accessed mostly through friends or colleagues (42.3%) and international conferences (36.6%). The commonest funding source was private (35.2%) and more than half stayed for less than 3 months. The visiting scholar's main roles were mostly observation or participation in surgery and clinical research. All but 1 were satisfied with the program (98.6%) and would recommend it to friends and colleagues, although the language barrier was identified as an inconvenience. Those aged 20-39 years with governmental or institutional funding were associated with stays of more than 1 year. CONCLUSION: The number of international visiting scholars at surgical departments in Korean hospitals has been on the increase with high satisfaction levels. Improvements need to be made on funding sources and lengthening visiting period to maximize the benefits of the program.

Medical students' perspectives on recommencing clinical rotations during coronavirus disease 2019 at one institution in South Korea.

PURPOSE: Clinical rotations of medical students across the world have inevitably been affected due to the coronavirus disease 2019 (COVID-19) pandemic. The aims of this study were to explore medical students' perception on the school's response and management of clinical rotation during the COVID-19 pandemic and on how it had affected the quality of their education. METHODS: An online questionnaire was distributed to third year medical students at one institution whose clinical rotations re-started during the pandemic. The questions asked about the students' satisfaction with the school's policy and feelings of safety, and the impact of COVID-19 on clinical learning. RESULTS: The students' perception on the school's response to the pandemic was mixed. Re-commencement of the clinical rotations and procurement of personal protective equipment was positive but a third of students still felt unsafe. The decreased number of hospital patients did not seem to have impacted their overall clinical education with praise on the role of the supervising physicians. Seventy-six-point seven percent of students conferred the positive educational opportunities on medical professionalism presented to them only as the clinical rotation during the ongoing pandemic. CONCLUSION: Our observations on the re-commencement of clerkship during this pandemic may help equip medical institutions on future public health crisis.

Minimally invasive complete mesocolic excision for right colon cancer.

Complete mesocolic excision (CME) with central vascular ligation (CVL) follows the same principles as the total mesorectal excision (TME) in the rectum of following the embryological planes for right-sided cancers. The number of lymph nodes yielded increased with a resultant improvement in the oncological outcomes and by reducing local recurrence rates. Hohenberger's radical CME and CVL and the East's modified CME with D3 lymphadenectomy, which traditionally followed the embryological plane dissection for most of its intraabdominal cancer resection, have both shown to harvest significantly higher number of lymph nodes leading to a higher overall survival rate than the traditional right hemicolectomies of the West. To achieve the oncologically superior excision of the CME, awareness of the significant vascular anatomical variation will enhance the precision of the oncosurgery as well as minimize the risk of vascular complications. There has been an increasing body of evidence emerging on the safety of minimally invasive surgery (MIS); both its oncological safety as well as complication rates in the hands of expert and trained surgeons. The surgical technique of a CME right hemicolectomy is described step by step to aid standardization. There is mounting evidence that CME + CVL/ D3 improves survival in patients with colon cancer. Whilst the technical aspect of MIS is more challenging than the left, with a standardized technique and systematic teaching method, safety and benefits for patients can be achieved.

The clinical significance of changes in red blood cell distribution width in patients with community-acquired pneumonia.

OBJECTIVE: Red cell distribution width (RDW) is associated with mortality in patients with community-acquired pneumonia (CAP). However, little is known about the effect of changes in RDW during treatment on mortality. Thus, the objective of this study was to evaluate the association between RDW changes and mortality in hospitalized patients with CAP. METHODS: Retrospective analyses were performed using medical records of patients hospitalized for CAP from April 2008 to February 2014. The abstracted laboratory values included RDW (from days one to four), clinical variables, and pneumonia severity index (PSI) scores. The ΔRDWn-1 was defined as the change in RDW calculated as: (RDWday1-RDWday-n)/RDWday1×100 (%), where 'day n' refers to hospital day. RESULTS: During the study period, a total of 1,069 patients were hospitalized for CAP. The 30-day mortality was 100/1,069 (9.4%). The median RDW at baseline was 14.1% (range, 11.1 to 30.2) and differed significantly between survivors and non-survivors (P<0.05). There were 470 patients with available serial RDW data (30-day mortality 58/470 [12.3%]). Of those, age, PSI score, blood urea nitrogen level, total protein concentration, albumin level, RDW at day 1, and the ΔRDW4-1 differed significantly between survivors and non-survivors. Multivariate Cox regression analysis showed that the significance of the relationship between ΔRDW4-1 and 30-day mortality risk remained after adjusting for age, PSI score, RDW at day 1, total protein concentration, and initial albumin level. CONCLUSION: RDW change from day 1 to day 4 was an independent predictor of mortality in patients with CAP.
