RESUMO
BACKGROUND: In this study, we aimed to evaluate the educational value and students' satisfaction with the hand-made low-cost cricothyrotomy simulation model. MATERIALS AND METHODS: A low-cost and hand-made model and a high-fidelity model were used to assess the students. The students' knowledge and satisfaction were evaluated using a 10-item checklist and a satisfaction questionnaire, respectively. Medical interns in the present study participated in a two-hour briefing and debriefing session held in the Clinical Skills Training Center by an emergency attending doctor. RESULTS: Based on the results of data analysis, no significant differences were found between the two groups in terms of gender, age, the month of internship, and last semester's grade (P = .628, .356, .847, and .421, respectively). We also found no significant differences between our groups in terms of the median score of each item in the assessment checklist (P = .838, .736, .805, .172, .439, .823, .243, .950, .812, and .756, respectively). The study groups had no significant difference in the median total scores of the checklist as well (P = .504). Regarding the students' satisfaction, our results showed that interns evaluated their experience of the model as positive (median scores of 4 and 5 out of 5). They also gave the hand-made model a median score of 7 in comparison with the high-fidelity model and 8 out of 10 for its usability. CONCLUSION: The study results showed that a low-cost model could be as effective as an expensive high-fidelity model for teaching the necessary knowledge of cricothyrotomy techniques to medical trainees.

BACKGROUND: Robotic-assisted surgery has become a common platform for performing colorectal procedures. Educators must determine how best to teach and train residents to use the technology safely. There is a paucity of literature on how non-operative skills are being taught and integrated into colorectal training. Herein we describe the implementation and assessment of a pilot simulation-based Robotic Colorectal Surgery Non-Technical Skills curriculum. MATERIALS AND METHODS: Since 2017 six colon and rectal surgery residents participated in two scenarios: pelvic bleeding and CO2 embolism. The scenarios were administered in a simulated operating room twice during the academic year (fall and spring), and audio-video recorded. In addition to self-assessment, videos were evaluated by faculty utilizing the validated Interpersonal and Cognitive Assessment for Robotic Surgery system. To understand the role of scenario difficulty with respect to perceived cognitive workload and performance residents completed a NASA-Task Load Index assessment form. RESULTS: Between the fall and spring sessions residents significantly improved in intraoperative leadership skills for both the CO2 embolism and bleeding scenarios, and decision-making and situational awareness for the embolism case. Assessment between resident (self) and expert (faculty) did not correlate (P < 0.05) for either scenario during the fall session. A correlation for both scenarios was appreciated following the spring session revealing resident non-technical skills improved over time. Other than for physical demand, NASA-Task Load Index scores were similar for both scenarios. CONCLUSIONS: We were able to successfully develop and implement a pilot Robotic Colorectal Surgery Non-Technical Skills curriculum in a risk-free simulated environment. Non-technical skill curriculums should be considered for both training and assessment in robotic surgery.

BACKGROUND: International medical graduates (IMGs) are often relegated to preliminary positions in general surgery (GS) owing to uncertainties about the candidate's performance in the American healthcare setting. We aimed to determine the comparative performance of IMGs and American medical graduates (AMGs) at baseline and assess these trends over the course of their GS internship. METHODS: Evaluations of all IMG preliminary and AMG categorical interns from 2013 to 2017 at our GS residency program were obtained from three faculty members to score overall performance, technical skills, interpersonal communication, and medical knowledge on a 10-point Likert scale. Scores on the American Board of Surgery In-Training Exam, an in-house preparation test, United States Medical Licensing Exam, and performance during the biannual multistation objective assessments were compared between the two resident groups. RESULTS: Seventy-two interns (28 [39%] AMG categorical and 44 [61%] IMG preliminary) met inclusion criteria. The AMG group had significantly higher median Step 1 and Step 2 scores compared with our IMG group (243 versus 231, P = 0.002, and 250 versus 246, P = 0.03, respectively).Although in-house preparation test scores were higher among IMGs (median [interquartile range] of 36 [33-40] among AMGs and 38 [34-45] among IMGs; P = 0.002), there were no statistically significant differences between the American Board of Surgery In-Training Exam scores of the two groups. The median scores for the four faculty evaluation components were similar between the AMG (7, 8, 7, 7) and IMG resident groups (7, 7, 7, 7; P = nonsignificant). IMGs scored significantly higher in both biannual multistation objective assessments than AMGs (median [interquartile range] July: 59 [47-91] versus 55 [37-62], P = 0.005; January: 103 [86-116] versus 91 [87-104], P = 0.03). CONCLUSIONS: It is reassuring to confirm that no matter where they are from, great candidates can perform well as surgical interns in a GS training program.

BACKGROUND: Our group has shown that personalized video feedback (PVF) is better than a task demonstration video at increasing wound closure skills among incoming surgical interns. However, offering PVF can be time-consuming. We sought to compare the educational effects and time required for group video feedback (GVF) and PVF. METHODS: We have mailed our matched incoming "surgical" interns a "welcome package" in mid-March for the past 3 y. The package includes similar resources each year. Incoming interns were asked to video record themselves performing six tasks three separate times between April 1 and June 15. After each submission in 2016 and 2017, incoming interns received 2 min of personalized feedback on their three separate wound closure videos (PVF). In 2018, incoming interns received 5 min of group-based feedback three separate times covering all six tasks (GVF). We compared performance (July Surgical Olympics) of these six skills against the interns from the previous 2 y who received PVF on only one skill (suturing). RESULTS: Twenty-three incoming interns received the pre-residency package and participated in the 2018 Surgical Olympics. This 2018 GVF class had a higher overall mean score for six stations (31.5 [standard deviation = ±7.7]) than the 2016 and 2017 PVF classes (25.6 [standard deviation = ±8]; P < 0.0001). Knot tying ability and suturing skill were similar between the classes. The GVF group performed better on the remaining four skills . The total time of surgical staff and educators spent per class in 2018 (GVF class) was 30 min and includes six tasks compared with 276 min of effort in each of the 2016 and 2017 classes (PVF included one task). CONCLUSIONS: GVF and PVF as a component of preemptive training had the same effect on improving suturing skills among the interns. GVF required less educator editing and voice over time. GVF is effective and efficient in enhancing incoming interns' performance in multiple skills.

BACKGROUND: Surgeons and gastroenterologists in training benefit from simulation-based endoscopy education, yet the price of most training endoscopy simulators is prohibitive. We set out to create and evaluate a low-cost endoscopic simulator and box model trainer for learning fundamental endoscopic skills. METHODS: After adding a wireless network-enabled camera (total cost, $20) to a discarded clinical endoscope, we paired this with an easily constructed box trainer (cost $32) to generate an endoscopic simulator system (YazanoScope) for simulation training. Participants (general surgery interns, research fellows, and medical and college students) used the YazanoScope to train to mastery on 5 FES tasks. Outcomes included skill assessments on a computer simulator and trainees' perceptions comparing the physical model to the computer simulator. RESULTS: Forty trainees participated. The median (range) training time was 110 (60-180) min. Only 10% of trainees were able to reach the cecum at baseline compared to 100% after training. The mean (SD) time was 253 (154) s at baseline (including completers and non-completers) and 249 (89) after training (P = 0.88). On a retention test 2 wk later, 21 of 22 (96%) completed the computer simulator assessment (endoscope tip reached the cecum). Mean time was 214 (67) s (P = 0.32 compared with immediate posttraining). All 40 trainees believed the YazanoScope provided better haptic feedback than the computer simulator. CONCLUSIONS: Training with this inexpensive, portable endoscopic simulator (YazanoScope) was associated with increased procedure completion with no change in procedure time. All participants favored the haptic feedback of the $52 YazanoScope over a computer simulator.

Self-regulated learning is optimized when instructional supports are provided. We evaluated three supports for self-regulated simulation-based training: practice schedules, normative comparisons, and learning goals. Participants practiced 5 endoscopy tasks on a physical simulator, then completed 4 repetitions on a virtual reality simulator. Study A compared two practice schedules: sequential (master each task in assigned order) versus unstructured (trainee-defined). Study B compared normative comparisons framed as success (10% of trainees were successful) versus failure (90% of trainees were unsuccessful). Study C compared a time-only goal (go 1 min faster) versus time + quality goal (go 1 min faster with better visualization and scope manipulation). Participants (18 surgery interns, 17 research fellows, 5 medical/college students) were randomly assigned to groups. In Study A, the sequential group had higher task completion (10/19 vs. 1/21; P < .001), longer persistence attempting an ultimately incomplete task (20.0 vs. 15.9 min; P = .03), and higher efficiency (43% vs. 27%; P = .02), but task time was similar between groups (20.0 vs. 22.6 min; P = .23). In Study B, the success orientation group had higher task completion (10/16 vs. 1/24; P < .001) and longer persistence (21.2 vs. 14.6 min; P = .001), but efficiency was similar (33% vs. 35%; P = .84). In Study C, the time-only group had greater efficiency than time + quality (56% vs. 41%; P = .03), but task time did not differ significantly (172 vs. 208 s; P = .07). In this complex motor task, a sequential (vs. unstructured) schedule, success (vs. failure) orientation, and time-only (vs. time + quality) goal improved some (but not all) performance outcomes.

BACKGROUND: Quality-improvement efforts at our institution have identified chest tube dislodgement as a preventable complication of tube thoracostomy. Because proper fixation techniques are not well described in the literature and are seldom formally taught, techniques vary among residents. OBJECTIVE: Our aim was to develop and test a framework for teaching and assessing chest tube securement. METHODS: A repeated-measures study design was used. At baseline, 19 emergency medicine residents (program years 1-3) placed and secured a chest tube in a cadaver. After a 45-min proficiency-based teaching session using a low-cost chest tube simulator (approximate cost, $5), each resident again placed and secured a chest tube in a cadaver, followed by 3-month retention testing. All securements were evaluated by two raters using a four-point checklist and a five-point global assessment scale (GAS). The checklist addressed suture selection, tying knots down to the tube, wound approximation, and tube displacement relative to skin. RESULTS: After the initial educational intervention, median scores for the group improved significantly over baseline for the GAS (p < 0.001), checklist (p < 0.001), and amount of displacement (p = 0.01). At 3 months, GAS, checklist, and displacement scores did not differ significantly from the immediate post-test scores. Inter-rater reliability was substantial, with weighted κ values of .77 for the GAS and .70 for the checklist. CONCLUSIONS: Quality of chest tube securement by emergency medicine residents can be significantly improved with an inexpensive chest tube simulator and a brief workshop. The four-point checklist served as a reliable and effective means for teaching and assessing chest tube securement.

A 56-year-old female diagnosed with hypertrophic obstructive cardiomyopathy and myocardial bridge (MB) of the left anterior descending (LAD) coronary artery underwent septal myectomy with resolution of her left ventricular outflow tract gradient. She had ongoing refractory symptoms of exertional angina and fatigue for over a decade and finally presented to our clinic to be re-evaluated for treatment. Provocative angiographic testing confirmed significant ischemia secondary to LAD MB. She underwent robotic totally endoscopic off pump unroofing of the LAD MB with complete relief of her symptoms and return to full activity. We conclude that patients undergoing septal myectomy for hypertrophic obstructive cardiomyopathy should be evaluated for MB and undergo unroofing of the bridge at the time of surgery. Learning objective: A myocardial bridge (MB) is a condition in which a coronary artery, most often the left anterior descending, takes an intramuscular route and is covered by the myocardium leading to compression and potential ischemia. This case report adds to the growing body of evidence supporting the significance of considering MB in the overall management of hypertrophic obstructive cardiomyopathy, and the symptomatic relief that a patient can obtain from an unroofing procedure.
RESUMO
OBJECTIVE: Femoral artery cannulation is the most commonly used approach for cardiopulmonary bypass (CPB) in robotic cardiac procedures. However, without adding a distal perfusion cannula, leg ischemia can occur in up to 11.5% of patients. There is a well-described 2 to 4 mm size arterial branch that originates from the medial side of the external iliac artery or inferior epigastric artery, immediately above the inguinal ligament, and connects to the obturator artery. Therefore, it was historically named the corona mortis, which means "crown of death" in Latin. When peripheral cannulation is performed above this branch in the external iliac artery, we consider it a corona "vitae" because of its role as a limb-saving collateral. We report herein our standard technique of peripheral cannulation without the need of a distal perfusion cannula and preventing limb ischemia. METHODS: We included all patients who underwent robotic cardiac surgery with peripheral cannulation over a 16-month period at our institution. We cannulated just above the level of the inguinal ligament through a 2 to 3 cm transverse skin incision. The incidence of limb ischemia and vascular complications was recorded and analyzed. RESULTS: During the study period, 133 patients underwent robotic cardiac procedures with peripheral "external iliac" CPB. The size of the cannula was 21F or larger in 73% and 23F in 54% of the patients. No leg ischemia or femoral artery complications requiring additional intervention occurred. CONCLUSIONS: External iliac cannulation can be successfully performed in robot-assisted cardiac surgery using relatively large cannulas without the need of a distal limb perfusion catheter, with good results. In our view, given the importance of the corona mortis ("crown of death" in Latin) in perfusing the limb during CPB, we propose a new name for this artery in robotic cardiac surgery, namely, the corona vitae ("crown of life" in Latin).

Hypertrophic obstructive cardiomyopathy is a disease of the heart in which the patient develops left ventricular outflow tract obstruction due to the interaction of the mitral valve and the intraventricular septum. Although septal myectomy remains the gold standard treatment for hypertrophic obstructive cardiomyopathy, several other approaches have been described in the literature, such as a transaortic, transapical or transmitral approach via a sternotomy. All of these approaches have been shown to produce reliable reduction in left ventricular outflow tract gradients. Robotic-assisted cardiac surgery has recently become a safe and effective alternative approach to a sternotomy for several intracardiac procedures, especially mitral valve repair and, in experienced centres, septal myectomy.

OBJECTIVE: Robotic totally endoscopic coronary artery bypass (TECAB) grafting is the least invasive form of coronary bypass surgery. However, despite its advantages, this approach has not gained widespread adoption. One possible reason is the advanced and complex robotic skills required to execute a totally endoscopic sutured coronary anastomosis. We prepared a novel, inexpensive, easy to set up robotic TECAB simulator. METHODS: A pig heart was placed in a cardboard box, and 3 holes were made on the side to mimic the exposure and surgical ergonomics of TECAB port placement. Four robotic ports were placed and docked to the da Vinci Si robot (Intuitive Surgical, Sunnyvale, CA, USA). Monofilament 7:0 suture (7 cm long) was used to perform the anastomosis to the left anterior descending artery using remnant conduit. Seven cardiac surgeons of various training levels participated and were asked to fill out a 10-point questionnaire. RESULTS: The cost of the simulator totaled $20 per session, with 20 min to assemble. Each session allowed each trainee to practice 3 to 4 coronary anastomoses. Three cardiac surgeons completed the survey and strongly agreed that the model was easy to set up, the anastomotic exercise was realistic, and that this practice helped them gain confidence. CONCLUSIONS: Our TECAB simulator is inexpensive, easy to set up, and allows trainees to practice endoscopic coronary suturing. We believe this to be a valuable training tool to learn how to do TECAB for established surgeons and that such a simulator may be of great value to cardiothoracic training programs and their trainees. Further studies are warranted.
RESUMO
INTRODUCTION: Accurately confirming surgical trainees have met the requirements of entrusted professional activities (EPAs) will require rigorous staff input. We pondered whether such simulation-driven evaluations might prove useful to the current ABS/APDS pilot effort on EPA analysis. METHODS: Our surgical trainees participate biannually in a 59-min simulation-based assessment (X-Games) which covers surgical technique, knowledge and critical thinking in a host of domains. The content and difficulty of the stations differed between the PGY levels. Only 4 EPA topics (inguinal hernia repair, appendectomy, cholecystectomy, and trauma resuscitation) were tabulated for this study. RESULTS: 16-PGY-2s, 8-PGY-3s, 10-PGY-4s, and 10-PGY-5s surgical residents completed the X-Games. Performance within and between PGY levels was variable. The mean(SD) EPA scores for all PGY levels are listed in Table- 1. CONCLUSION: Analysis gleaned from a 59-min OSCE in a simulated-setting offers objective data that appears to have construct-validity. Refining our Surgical X-Games to cater to the specific EPA scoring system may better allow objective analysis of when trainees cross the threshold from "can do with some help" to "can do autonomously".

OBJECTIVE: While dedicated research time (DRT) offers international medical graduates (IMGs) exposure to the US healthcare system and helps boost their residency application, it can lengthen time away from clinical activity. We aimed to determine the value of DRT/protected research time for an IMG applying to general surgeryresidency (GSR). DESIGN: Cross-sectional survey. SETTING: Academic, tertiary care center with a large GSR program (Mayo Clinic, Rochester, MN). PARTICIPANTS: IMG applicants to our GSR program (2015-2018) and general surgery program directors (PDs) in the United States. METHODOLOGY: Separate surveys were emailed to all IMG applicants to our GSR program (2015-2018) and general surgery PDs. Surveys to the applicants focused on the details of DRT spent in the US prior to residency and match outcomes. Surveys to the PDs focused on the importance of different aspects of an IMG applicant's research experience. RESULTS: Applicants: 320 applicants responded of which 148 (46%) applicants spent DRT in the US prior to residency. Among the research group, the median (interquartile range [IQR]) number of first author podium and poster presentations from the DRT were 1 (0-4) and 2 (1-5), respectively. At the time of match application, the median (IQR) number of published manuscripts among the research group was higher than that among the applicant group which did not pursue DRT (5[2-12] vs 1[0-2], p < 0.0001). Pursuing DRT and/or the duration of the research did not affect the match outcomes (p > 0.05). PROGRAM DIRECTORS: Seventy-six PDs responded to our survey. A median (IQR) of 2.5 (2-3) publications, and 2 (2-3) presentations per year of DRT were considered "productive." Sixty-three percent of PDs did not recommend IMGs take time off to engage in research; only 54% attributed some importance to an IMG's research experience. CONCLUSIONS: DRT does not seem to be associated with better outcomes for IMGs targeting GSR. Most PDs advocate against taking time off after graduation to engage in research activity. Decisions to pursue DRT should be individualized.

BACKGROUND: Selecting the right applicants for general surgery training is critical and difficult. We refined our selection process by using a pre-interview preparation package and simulation-based assessments. METHODS: Sixty applicants invited for categorical general-surgery residency interview were mailed an educational package which included a link to instructional videos, surgical instruments and low-cost models for suturing, open knot tying, and adrenal anatomy knowledge. During the interview day, applicants participated in a 48-min simulation-based assessment consisting of same tasks included in the package. Performance scores were used to assist in ranking applicants. The matched 2018class was compared to our previous intern classes on several objective assessments (Surgical-Olympics and ABSITE score). RESULTS: Students scored >50tile moved high in our final rank-list. The 2018 class scored significantly higher in 10 of 15 Surgical-Olympic stations compared to our 2015-17class with no significant difference on ABSITE score. CONCLUSIONS: By mailing out a pre-interview welcome package and adding a simulation based assessment to our General Surgery categorical interview process, we believe early objective data suggests we positively influenced our 2018 NRMP match.

This case presentation involves a 57-year-old-male who suffered multiple adverse sequels from the delayed diagnosis of a large presacral mass. He initially presented with lower extremity deep vein thrombosis (DVT). Several months later, he had developed a pulmonary embolus. Imaging demonstrated a 13 × 14 cm presacral pelvic mass that occluded the right-sided venous return from the leg and caused the DVT and pulmonary embolism. An inferior vena cava filter was placed and eventually clotted. He then was referred to our institution for surgical consultation. The patient received lytic therapy and unfortunately developed hematemesis and a significant hemoglobin drop. An esophagogastroduodenoscopy (EGD) showed a black esophagus. A transthoracic echocardiogram showed a patent foramen ovale. The patient eventually stabilized and a repeat EGD a week later showed resolution of the ischemic esophagus. The patient later underwent a resection of the pelvic mass. The surgical approach and the surgical decision-making will be discussed.
RESUMO
BACKGROUND: Human understanding of how to efficiently train learners in procedural skills is imperfect. The concept of self-efficacy - confidence in one's ability to successfully complete a task - may be useful to learners. Theories of motivation and instructional design suggest there are specific targets for improving learner success. We aimed to study the effects of induced conceptions of ability on motor learning using both undergraduate and medical students. METHODS: Forty undergraduate and medical students underwent a 15-minute training session teaching the basics of colonoscopy on a low-cost, moderate fidelity colonoscopy simulation model. Students were then tasked to intubate the cecum of a similarly constructed colonoscopy model with a real colonoscope. Before each task, participants were given a note which either read "90% of your peers completed the task in less than 5 minutes" (positive [+] comparison group) or "10% of your peers completed the task in less than 5 minutes" (negative [-] comparison group). Immediately after receiving the note, participants were then asked to complete a self-efficacy questionnaire, ranking their confidence on a scale from 0 to 10 for successfully completing the task. A NASA TLX was collected to understand the students' mental effort with the task. Participants then underwent stratified randomization into 2 crossover groups (G1â¯=â¯+ note, then - note; G2â¯=â¯- note, thenâ¯+â¯note) and again performed the colonoscopy task. Following the session completion, all students had received both notes and crossed over to complete both tasks. Time spent on both tasks and task completion (reaching the cecum) was the measured outcomes. RESULTS: Self-efficacy (confidence) levels were significantly higher in the positive note condition for both comparison groups in (p < 0.05). However, task completion rates were higher in the negative note group in Task 1 (p < 0.05) and the same in Task 2 (pâ¯=â¯0.6). Time spent by participants in each task was longer in the negative note groups in both tasks (pâ¯=â¯0.06 in Task 1; pâ¯=â¯0.07 in Task 2). No difference was found between both groups in the mental effort after each task (Table 1). CONCLUSIONS: This prospective, cross-over study suggests that performance expectancies can be influenced by preinduced conceptions. Performance was enhanced in Task 1 when participants were given a relatively "low success rate prediction." This may be due to an enhanced focus that led to increased performance-while participants who were given the prediction of a "higher success rate" were more confident but performed less well. The crossover groups for Task 2 performed in a similar manner despite different confidence levels. This study supports the idea that self-efficacy expectations are relevant for trainee education and performance.

INTRODUCTION: Knowledge of anatomy is essential for surgeons. We sought to determine whether it is possible to effectively assess and differentiate the anatomic knowledge of general surgery residents, using pieces of fabric and yarn. METHODS: Postgraduate years 2, 3, and 4 general surgery residents were assessed during a simulation-based assessment known as the Surgical X-Games. Residents were allowed 3 minutes to assemble the anatomic structures of the right upper quadrant region and 2 minutes to create the right lower quadrant of the abdomen, using colored felt and yarn. One point (each) was given for naming and placing the structures in the correct position. A checklist was used to assess trainees with a maximum combined score of 150 points. RESULTS: A total of 34 residents (postgraduate year 2 = 16, postgraduate year 3 = 8, postgraduate year 4 = 10) participated in the 2017 fall Surgical X-Games and 31 residents (postgraduate year 2 = 13, postgraduate year 3 = 9, postgraduate year 4 = 9) participated in the spring Surgical X-Games. Total scores increased respective to the level of clinical training in both the fall Surgical X-Games (postgraduate year 2 = 77, postgraduate year 3 = 84, postgraduate year 4 = 93, P = .04) and the spring Surgical X-Games (postgraduate year 2 = 94, postgraduate year 3 = 101, postgraduate year 4 = 109). We observed significant improvement in the right upper quadrant, right lower quadrant, and total scores from the fall to the spring postgraduate year (P < .001). CONCLUSION: Surgical residents showed an increase in mean anatomical scores from postgraduate years 2 to postgraduate years 3 to postgraduate years 4, using low-fidelity models. This inexpensive, 5-minute test based on a simple checklist may offer surgical educators insight in to residents' anatomic knowledge and potential readiness for clinical rotations.

BACKGROUND: The transition from fourth-year medical student to surgical intern is difficult. A lack of repetitions, experience, and knowledge is problematic. We report our experience using simulation-based technical and nontechnical skills to assess the competency of surgical interns in July and January of their intern year. DESIGN: As part of a larger assessment effort, our general surgery interns (2010-2016) have been tested on performing an emergent cricothyrotomy, interpreting 2 arterial blood gases, and reading 3 chest x-rays in fewer than 7 minutes. We retrospectively analyzed general surgery interns' performance on these 3 tests (total score = 20). RESULTS: A total of 210 interns completed both July and January (identical) assessments. Overall mean scores improved from July (12.62 ± 3.44) to January (16.5 ± 2.46; P < .05). During the study period general surgery interns' mean baseline scores improved in both July (P < .05) and in January (P < .05). Although most individual general surgery interns did improve their total scores (92% improved, 3% same, 5% worse) between July and January (P < .05), in January 40% could not perform an emergent cricothyrotomy swiftly, and 6% missed a tension pneumothorax on chest x-ray. CONCLUSION: Our data suggest that surgical interns start residency training with low levels of skill and comprehension with emergent cricothyrotomy, arterial blood gas, and chest x-ray. They improve with 6 months of clinical and simulation training. Encouragingly, overall scores for both July and January assessments have improved during the study period. Given that some interns still struggle in January to perform these three tasks, we believe that 2018 interns are better, but still potentially lack critical knowledge and skill.

OBJECTIVE: Simulation sutures are a low-cost option for training purposes, but they may not perform as well as the more expensive clinical suture. Trainees at our institution have raised concerns about their quality and integrity compared with clinical suture. The objective was to determine whether significant differences in strength of the sutures and knot holding capabilities between low and high-cost sutures existed. METHODS: Two sutures were compared: 3-0 braided silk simulation suture (Sim*Vivo LLC, Willsboro, NY) and 3-0 Perma-Hand silk braided clinical suture (Ethicon, Somerville, NJ). The diameter of the suture was assessed with light microscopy. Tensile strength of the suture and knotted suture were assessed. Both sutures were tested dry and wet. RESULTS: Tensile strength of the sutures, knotted or unknotted, were not significantly different. Knot type did not change this comparison. Soaking in saline did not change the tensile strength but did introduce a substantial difference in knot failure mode between sutures. The mean diameter of the Ethicon suture was larger than that of the Sim*Vivo suture, which could influence suture behavior. CONCLUSIONS: The applied mechanical tests identified that clinical and simulation sutures differ some in their inherent mechanical characteristics related to suture handling. However, these differences did not translate to a key measure of performance of a sutured junction, namely, the strength of the knotted suture. Based on the results of the study, any subjective impressions of simulation suture strength and knot holding should not negatively impact its use for medical education.

BACKGROUND: Continuous Ambulatory Peritoneal Dialysis (CAPD) catheter placement is typically a straightforward surgical procedure performed on chronically ill patients with end-stage renal disease (ESRD). Post-operative outcomes and reoperative rates vary greatly in the medical literature. We report our experience using both minimally invasive and open techniques in placing CAPD catheters and offer our surgical outcomes. METHODS: This study is an IRB-approved, retrospective review (2005-2018) of all patients undergoing CAPD catheter placement at Mayo Clinic-Rochester. Analysis focused on specific patient outcomes, including early (< 30â¯days) versus late (≥ 30â¯days) complication and reoperation rates. RESULTS: A total of 173 patients with ESRD (mean ASA scoreâ¯=â¯3.1) underwent laparoscopic (nâ¯=â¯22) and open (nâ¯=â¯151) CAPD catheter placement (mean follow-upâ¯=â¯309â¯days; range: 1-3497â¯days). The total index operation complication rate was 41%. The total index reoperation rate was 37% and was similar in open and laparoscopic approaches. CAPD catheters malfunctioned in 19 patients (11% of total) and each underwent reoperation. CAPD catheter infections occurred in 30 patients (17% of total), and 24 required reoperation; 6 patients were treated successfully with antibiotics. CAPD catheter migrations occurred in 21 patients (12% of total) and all underwent reoperation. CONCLUSION: Although CAPD catheter placements in patients with ESRD are technically easy to accomplish, the long term outcomes suggest as many as one in three patients will struggle with catheter function or infection. This study has led to changes in our technical CAPD catheter placement procedures, as well as the post-operative patient care algorithm.
