The Predictive Performance of General Surgery Milestones on Post-Graduation Outcomes.

OBJECTIVE: To establish whether Accreditation Council for Graduate Medical Education Milestones predict future performance of general surgery trainees. SUMMARY BACKGROUND DATA: Milestones provide bi-annual assessments of trainee progress across six competencies. It is unknown whether the Milestones predict surgeon performance after the transition to independent practice. METHODS: We performed a retrospective cohort study of surgeons with complete Milestone assessments in the fourth and fifth clinical years who treated patients in acute care hospitals within Florida, New York, and Pennsylvania, 2015-2018. To account for the multiple ways in which the Milestone assessments might predict post-graduation outcomes, we included 120 Milestones features in our elastic net machine learning models. The primary outcome was risk-adjusted patient death or serious morbidity. RESULTS: 278 general surgeons were included in the study. Milestone assessments 6-months into the fourth clinical year displayed a normal score distribution while multicollinearity and low score discrimination at the final assessment period were detected. Individual Milestones features from the Patient Care, Professionalism, and Systems-based Practice domains were most predictive of patient-related outcomes. For example, surgeons with worse patient outcomes had significantly lower scores in Patient Care 3 when compared to surgeons with better patient outcomes (High DSM, yes: 2.86 vs. no: 3.04, P=0.011). CONCLUSIONS: The Milestones features that were most predictive of better patient outcomes related to intraoperative skills, ethical principles, and patient navigation and safety, measured 12-18 months prior to graduation. The development of a parsimonious set of evidence-based Milestones that better correlate with surgeon experience could enhance surgical education.

Accreditation Council for Graduate Medical Education Milestone Training Ratings and Surgeons' Early Outcomes.

Importance: National data on the development of competence during training have been reported using the Accreditation Council for Graduate Medical Education (ACGME) Milestones system. It is now possible to consider longitudinal analyses that link Milestone ratings during training to patient outcomes data of recent graduates. Objective: To evaluate the association of in-training ACGME Milestone ratings in a surgical specialty with subsequent complication rates following a commonly performed operation, endovascular aortic aneurysm repair (EVAR). Design, Setting, and Participants: This study of patient outcomes followed EVAR in the Vascular Quality Initiative (VQI) registry (4213 admissions from 208 hospitals treated by 327 surgeons). All surgeons included in this study graduated from ACGME-accredited training programs from 2015 through 2019 and had Milestone ratings 6 months prior to graduation. Data were analyzed from December 1, 2021, through September 15, 2023. Because Milestone ratings can vary with program, they were corrected for program effect using a deviation score from the program mean. Exposure: Milestone ratings assigned to individual trainees 6 months prior to graduation, based on judgments of surgical competence. Main Outcomes and Measures: Surgical complications following EVAR for patients treated by recent graduates during the index hospitalization, obtained using the nationwide Society for Vascular Surgery Patient Safety Organization's VQI registry, which includes 929 participating centers in 49 US states. Results: The study included outcomes for 4213 patients (mean [SD] age, 73.25 [8.74] years; 3379 male participants [80.2%]). Postoperative complications included 9.5% major (400 of 4213 cases) and 30.2% minor (1274 of 4213 cases) complications. After adjusting for patient risk factors and site of training, a significant association was identified between individual Milestone ratings of surgical trainees and major complications in early surgical practice in programs with lower mean Milestone ratings (odds ratio, 0.50; 95% CI; 0.27-0.95). Conclusions and Relevance: In this study, Milestone assessments of surgical trainees were associated with subsequent clinical outcomes in their early career. Although these findings represent one surgical specialty, they suggest Milestone ratings can be used in any specialty to identify trainees at risk for future adverse patient outcomes when applying the same theory and methodology. Milestones data should inform data-driven educational interventions and trainee remediation to optimize future patient outcomes.

Supersaturation dependent nucleation of methane + propane mixed-gas hydrate.

Before hydrates can be widely used in industry, we should better understand the problematic issues of hydrate nucleation, particularly its stochastic nature. Here, we report on measurements of the nucleation probability of mixed-gas hydrates in which the guest molecules are a mixture of methane and propane. For the pure cases, at a supersaturation near 1.0, we had previously measured an induction time for the methane hydrate of about 1 h, whereas for the propane hydrate, it was over one day. Using the same experimental setup, we examine here the nucleation probability for a mixture of 90% methane and 10% propane as the guest gas for a range of supersaturations. For the experiments, the temperature was 274 ± 0.5 K and the stirring rate was about 300 rpm. The experiments were repeated at least ten times under the same condition, exchanging the sample water every time. We define the nucleation probability at a given time as the fraction of trials that nucleated by that time and then determine the nucleation probability distribution. The resulting nucleation frequency is found to have a power-law relation to supersaturation. Then, we examine how the nucleation frequency is affected by the existence of ultrafine bubbles in the initial water. We find that the ultrafine bubbles increase the nucleation frequency but much less than that of typical changes in supersaturation.

The Association of ACGME Milestones With Performance on American Board of Surgery Assessments: A National Investigation of Surgical Trainees.

OBJECTIVE: To determine the relationship between, and predictive utility of, milestone ratings and subsequent American Board of Surgery (ABS) vascular surgery in-training examination (VSITE), vascular qualifying examination (VQE), and vascular certifying examination (VCE) performance in a national cohort of vascular surgery trainees. BACKGROUND: Specialty board certification is an important indicator of physician competence. However, predicting future board certification examination performance during training continues to be challenging. METHODS: This is a national longitudinal cohort study examining relational and predictive associations between Accreditation Council for Graduate Medical Education (ACGME) Milestone ratings and performance on VSITE, VQE, and VCE for all vascular surgery trainees from 2015 to 2021. Predictive associations between milestone ratings and VSITE were conducted using cross-classified random-effects regression. Cross-classified random-effects logistic regression was used to identify predictive associations between milestone ratings and VQE and VCE. RESULTS: Milestone ratings were obtained for all residents and fellows(n=1,118) from 164 programs during the study period (from July 2015 to June 2021), including 145,959 total trainee assessments. Medical knowledge (MK) and patient care (PC) milestone ratings were strongly predictive of VSITE performance across all postgraduate years (PGYs) of training, with MK ratings demonstrating a slightly stronger predictive association overall (MK coefficient 17.26 to 35.76, ß = 0.15 to 0.23). All core competency ratings were predictive of VSITE performance in PGYs 4 and 5. PGY 5 MK was highly predictive of VQE performance [OR 4.73, (95% CI, 3.87-5.78), P <0.001]. PC subcompetencies were also highly predictive of VQE performance in the final year of training [OR 4.14, (95% CI, 3.17-5.41), P <0.001]. All other competencies were also significantly predictive of first-attempt VQE pass with ORs of 1.53 and higher. PGY 4 ICS ratings [OR 4.0, (95% CI, 3.06-5.21), P <0.001] emerged as the strongest predictor of VCE first-attempt pass. Again, all subcompetency ratings remained significant predictors of first-attempt pass on CE with ORs of 1.48 and higher. CONCLUSIONS: ACGME Milestone ratings are highly predictive of future VSITE performance, and first-attempt pass achievement on VQE and VCE in a national cohort of surgical trainees.

Industry Payments Received by Residents During Training.

Importance: Those responsible for medical education-specialties, sponsoring institutions, and program directors (PD)-are independently associated with the professional identity formation of the trainees with respect to potential conflicts of interest. Objective: To identify the relative degree to which factors in the training environment are associated with resident acceptance of payments from pharmaceutical and medical device companies. Design, Setting, and Participants: Cross-sectional, retrospective study of residents enrolled in the 3 largest primary-care specialties (internal medicine [IM], family medicine [FM], obstetrics and gynecology [OBGYN]) and 3 largest surgical disciplines (general surgery [GS], orthopedic surgery, and urology) during academic year 2020 to 2021. All analyses were conducted January through August 2023. Exposures: Specialty, sponsoring institutions' ownership (nonprofit, for-profit, federal government, local government, or state government), and the number of payments PDs accepted. Main outcomes and measures: Modified Poisson regression assessed the relative risk of ownership, specialty, and PD behavior on residents' acceptance of industry payments as recorded in the Open Payments Program (OPP) database. Results: In total, there were 124 715 residents in all training programs during 2020 to 2021, 12% of whom received payments totaling $6.4 million. There were 65 992 residents in training during 2020 to 2021 in the 6 specialties evaluated in this study, with 4438 in orthopedics, 1779 in urology, 9177 in GS, 5819 in OBGYN, 14 493 in FM, and 30 286 in IM. OPP records $3.9 million in payments to the 8750 residents (13.4%) who received at least 1 industry payment. The record of all payments to residents in OPP totals $6.4 million. Compared with residents in federal sponsoring institutions, those affiliated with for-profit institutions were 3.50 (95% CI, 2.32-5.28) times more likely to accept industry payments, while those affiliated with nonprofit organizations were 2.00 (95% CI, 1.36-2.93) times more likely to accept payments. Compared with IM, residents in each of the following specialties have an elevated risk of accepting payments: orthopedics, 3.21 (95% CI, 2.73-3.77) times; urology, 2.95 (95% CI, 2.44-3.56) times; GS, 1.21 (95% CI, 1.00-1.45) times; OBGYN, 1.30 (95% CI, 1.05-1.62) times. The difference in the risk of accepting a payment between FM and IM residents was not statistically significant. The number of payments PDs accepted slightly elevated the risk of residents to accept a payment by 1.01 (95% CI, 1.01-1.01). Conclusions and relevance: In this cross-sectional, retrospective study, receipt of industry payments by residents was associated with specialty, institutional control, and PD behavior.

Gender Bias and Ophthalmology Accreditation Council for Graduate Medical Education Milestones Evaluations.

Importance: Women remain underrepresented in ophthalmology and gender-based disparities exist in salary, grant receipt, publication rates, and surgical volume throughout training and in practice. Although studies in emergency medicine and general surgery showed mixed findings regarding gender differences in Accreditation Council for Graduate Medical Education (ACGME) Milestones ratings, limited data exist examining such differences within ophthalmology. Objective: To examine gender differences in ophthalmology ACGME Milestones. Design, Setting, and Participants: This was a retrospective cross-sectional study of postgraduate year 4 (PGY-4) residents from 120 ophthalmology programs graduating in 2019. Main Outcomes and Measures: PGY-4 midyear and year-end medical knowledge (MK) and patient care (PC) ratings and Written Qualifying Examination (WQE) scaled scores for residents graduating in 2019 were included. Differential prediction techniques using Generalized Estimating Equations models were performed to identify differences by gender. Results: Of 452 residents (median [IQR] age, 30.0 [29.0-32.0] years), 275 (61%) identified as men and 177 (39%) as women. There were no differences in PC domain average between women and men for both midyear (-0.07; 95% CI, -0.11 to 0; P =.06) and year-end (-0.04; 95% CI, -0.07 to 0.03; P =.51) assessment periods. For the MK domain average in the midyear assessment period, women (mean [SD], 3.76 [0.50]) were rated lower than men (mean [SD], 3.88 [0.47]; P = .006) with a difference in mean of -0.12 (95% CI, -0.18 to -0.03). For the year-end assessment, however, the average MK ratings were not different for women (mean [SD], 4.10 [0.47]) compared with men (mean [SD], 4.18 [0.47]; P = .20) with a difference in mean of -0.08 (95% CI, -0.13 to 0.03). Conclusions and Relevance: Results suggest that ACGME ophthalmology Milestones in 2 general competencies did not demonstrate major gender bias on a national level at the time of graduation. There were, however, differences in MK ratings at the midyear mark, and as low ratings on evaluations and examinations may adversely affect career opportunities for trainees, it is important to continue further work examining other competencies or performance measures for potential biases.

Association of Surgical Resident Competency Ratings With Patient Outcomes.

PURPOSE: Accurate assessment of clinical performance is essential to ensure graduating residents are competent for unsupervised practice. The Accreditation Council for Graduate Medical Education milestones framework is the most widely used competency-based framework in the United States. However, the relationship between residents' milestones competency ratings and their subsequent early career clinical outcomes has not been established. It is important to examine the association between milestones competency ratings of U.S. general surgical residents and those surgeons' patient outcomes in early career practice. METHOD: A retrospective, cross-sectional study was conducted using a sample of national Medicare claims for 23 common, high-risk inpatient general surgical procedures performed between July 1, 2015, and November 30, 2018 (n = 12,400 cases) by nonfellowship-trained U.S. general surgeons. Milestone ratings collected during those surgeons' last year of residency (n = 701 residents) were compared with their risk-adjusted rates of mortality, any complication, or severe complication within 30 days of index operation during their first 2 years of practice. RESULTS: There were no associations between mean milestone competency ratings of graduating general surgery residents and their subsequent early career patient outcomes, including any complication (23% proficient vs 22% not yet proficient; relative risk [RR], 0.97, [95% CI, 0.88-1.08]); severe complication (9% vs 9%, respectively; RR, 1.01, [95% CI, 0.86-1.19]); and mortality (5% vs 5%; RR, 1.07, [95% CI, 0.88-1.30]). Secondary analyses yielded no associations between patient outcomes and milestone ratings specific to technical performance, or between patient outcomes and composites of operative performance, professionalism, or leadership milestones ratings ( P ranged .32-.97). CONCLUSIONS: Milestone ratings of graduating general surgery residents were not associated with the patient outcomes of those surgeons when they performed common, higher-risk procedures in a Medicare population. Efforts to improve how milestones ratings are generated might strengthen their association with early career outcomes.

Giant Coronary Aneurysm with Coronary-Pulmonary Artery Fistula in a Jehovah's Witness.

With an incidence of 3 in 100 million, giant coronary artery aneurysm (CAA) with coronary artery fistula (CAF) is a very rare condition. To prevent rupture, giant CAA with CAF should be swiftly treated. We present a Jehovah's Witness patient with giant CAA and coronary-pulmonary artery fistula. We resected the giant CAA in one piece, while ligating the CAF, without allogeneic blood transfusion. Due to rarity of these conditions, many thoracic surgeons lack direct experience in its surgical procedures. Herein, we share footage of this surgery as an example of how to safely resect CAA with minimal bleeding.

Predicting Performance at Graduation From Early ACGME Milestone Ratings: Longitudinal Learning Analytics in Professionalism and Communication in Vascular Surgery.

OBJECTIVE: Program directors in surgical disciplines need more tools from the ACGME to help them use Milestone ratings to improve trainees' performance. This is especially true in competencies that are notoriously difficult to measure, such as professionalism (PROF) and interpersonal and communication skills (ICS). It is now widely understood that skills in these two areas have direct impact on patient care outcomes. This study investigated the potential for generating early predictors of final Milestone ratings within the PROF and ICS competency categories. DESIGN: This retrospective cohort study utilized Milestone ratings from all ACGME-accredited vascular surgery training programs, covering residents and fellows who completed training in June 2019. The outcome measure studied was the rate of achieving the recommended graduation target of Milestone Level 4 (possible range: 1-5), while the predictors were the Milestone ratings attained at earlier stages of training. Predictive probability values (PPVs) were calculated for each of the 3 PROF and two ICS sub-competencies to estimate the probability of trainees not reaching the recommended graduation target based on their previous Milestone ratings. SETTING: All ACGME-accredited vascular surgery training programs within the United States. PARTICIPANTS: All trainees completing a 2 year vascular surgery fellowship (VSF) in June 2019 (n = 119) or a 5 year integrated vascular surgery residency (IVSR) in June 2019 (n = 52) were included in the analyses. RESULTS: The overall rate of failing to achieve the recommended graduation target across all PROF and ICS sub-competencies ranged from 7.7% to 21.8% of all trainees. For trainees with a Milestone rating at ≤ 2.5 with 1 year remaining in their training program, the predictive probability of not achieving the recommended graduation target ranged from 37.0% to 71.5% across sub-competencies, with the highest risks observed under PROF for "Administrative Tasks" (71.5%) and under ICS for "Communication with the Healthcare Team" (56.7%). CONCLUSIONS: As many as 1 in 4 vascular surgery trainees did not achieve the ACGME vascular surgery Milestones targets for graduation in at least one of the PROF and ICS sub-competencies. Biannual ACGME Milestone assessment ratings of PROF and ICS during early training can be used to predict achievement of competency targets at time of graduation. Early clues to problems in PROF and ICS enable programs to address potential deficits early in training to ensure competency in these essential non-technical skills prior to entering unsupervised practice.

The Use of Learning Analytics to Enable Detection of Underperforming Trainees: An Analysis of National Vascular Surgery Trainee ACGME Milestones Assessment Data.

OBJECTIVE: This study aims to investigate at-risk scores of semiannual Accreditation Council for Graduate Medical Education (ACGME) Milestone ratings for vascular surgical trainees' final achievement of competency targets. SUMMARY BACKGROUND DATA: ACGME Milestones assessments have been collected since 2015 for Vascular Surgery. It is unclear whether milestone ratings throughout training predict achievement of recommended performance targets upon graduation. METHODS: National ACGME Milestones data were utilized for analyses. All trainees completing 2-year vascular surgery fellowships in June 2018 and 5-year integrated vascular surgery residencies in June 2019 were included. A generalized estimating equations model was used to obtain at-risk scores for each of the 31 subcompetencies by semiannual review periods, to estimate the probability of trainees achieving the recommended graduation target based on their previous ratings. RESULTS: A total of 122 vascular surgery fellows (VSFs) (95.3%) and 52 integrated vascular surgery residents (IVSRs) (100%) were included. VSFs and IVSRs did not achieve level 4.0 competency targets at a rate of 1.6% to 25.4% across subcompetencies, which was not significantly different between the 2 groups for any of the subcompetencies ( P = 0.161-0.999). Trainees were found to be at greater risk of not achieving competency targets when lower milestone ratings were assigned, and at later time-points in training. At a milestone rating of 2.5, with 1 year remaining before graduation, the at-risk score for not achieving the target level 4.0 milestone ranged from 2.9% to 77.9% for VSFs and 33.3% to 75.0% for IVSRs. CONCLUSION: The ACGME Milestones provide early diagnostic and predictive information for vascular surgery trainees' achievement of competence at completion of training.

[A Case of pagetoid Carcinoma of the Breast with Pathological Complete Response by Neoadjuvant Chemotherapy].

We herein report a 63-year-old woman who presented with about 20 mm-sized mass in the right breast and the right nipple with erosion. Preoperative examinations revealed a diagnosis of HER2-type pagetoid carcinoma with axillary lymph node metastasis. After neoadjuvant chemotherapy(pertuzumab, trastuzumab, and docetaxel, followed by adriamycin and cyclophosphamide), a pathological complete response was achieved. The patient was treated with anti-HER2 therapy without recurrence.

[A Case of Long-Term Survival Achieved by Multimodal Treatments for Postoperative Lung Metastasis and Mediastinal Lymph Node Metastasis after Surgery for Ascending Colon Cancer].

A 52-year-old male patient with Stage Ⅲc ascending colon cancer underwent laparoscopic right hemicolectomy with D3 lymph node dissection. Adjuvant chemotherapy was administered for 6 months, and no recurrence was observed during the follow-up period. Left lung metastasis was detected and surgically removed 7 years after the initial surgery. He underwent open partial small bowel resection with lymph node dissection when mesenteric lymph node metastasis was identified 2 years later. Although chemotherapy was conducted on the identification of mediastinal lymph node metastasis 2 years later, the mediastinal lymph nodes increased. Although attempted, lymph node dissection was impossible because of the strong adhesion to the trachea. Subsequently, chemotherapy and radiation therapy were administered. However, an infiltration of the mediastinal lymph nodes into the trachea was observed. The patient underwent bronchoscopic laser tumor ablation. The patient died 4 months after the resumption of chemotherapy(18 years after the initial surgery). Mediastinal lymph node recurrence after curative resection for colon cancer is a rare clinical condition. Nevertheless, long-term survival could be achieved by multimodal treatments in such patients.

Successful endoscopic clipping management of a left atrioesophageal fistula after atrial fibrillation catheter ablation: A case report of a young male patient.

Atrioesophageal fistula (AEF) is a rare and serious complication of atrial fibrillation (AF) ablation, forming a connection between the atrium and esophagus. A systematic treatment approach for AEF has not been established to date. Herein, we report the case of a young male patient with left AEF after AF catheter ablation, which was successfully treated with the Over-the-Scope Clip (Ovesco Endoscopy AG, Tübingen, Germany) and conservative management. Despite having a double-orifice mitral valve and tricuspid valve, the patient had no symptoms or valve disease. The patient was readmitted three weeks after the procedure owing to fever, hematemesis, consciousness disturbance, hemiplegia, and systemic convulsions. Indigenous bacteria in the oral cavity were detected in blood culture. Magnetic resonance imaging of the brain showed multiple cerebral infarctions. Chest computed tomography showed mediastinal air, suggesting an AEF diagnosis. Subsequently, an endoscopic closure using the Over-the-Scope Clip was performed, leading to a successful recovery and patient discharge on day 87 after admission. This is the first case report of a successful management of AEF after radiofrequency ablation using the Over-the-Scope Clip system. Although surgery is the main treatment for AEFs, we performed nonsurgical management using the clip, demonstrating a potential treatment option for AEF. Learning objective: Surgical intervention is usually superior to endoscopic intervention and conservative management for treatment of atrioesophageal fistula. To the best of our knowledge, this is the first case to be successfully managed by endoscopic clipping and conservative management.

Trends in Industry Payments to Physicians in the First 6 Years After Graduate Medical Training.

Importance: Financial incentives and conflicts of interest may influence physician decision-making. It is important to understand financial interactions between the pharmaceutical and medical device industries and newly independent physicians who have recently completed their graduate medical education using a national transparency program. Objective: To identify trends in industry payments to recent graduates of Accreditation Council for Graduate Medical Education-accredited residency or fellowship programs in orthopedic surgery, neurosurgery, and internal medicine. Design, Setting, and Participants: This retrospective cohort study analyzed Open Payments reports of industry payments made between July 1, 2015, and June 30, 2021, to newly independent physicians from residency or fellowship programs in neurosurgery, orthopedic surgery, and internal medicine who graduated between January 1, 2015, and December 31, 2019. Exposures: Specialties (neurosurgery and orthopedic surgery, with internal medicine as a comparison group). Main Outcomes and Measures: Industry payments to newly independent physicians, including any general payments (noninvestment or nonresearch) and at least $5000 of general payments in aggregate value per year, which are considered significant financial conflicts of interest. The percentage of newly independent physicians accepting general payments during the first 6 years after graduation was analyzed by specialty and sex using cumulative incidence curves and hazard ratios (HRs) in univariable and multivariable analyses. Results: There were 45 745 recent graduates (28 137 men [62%]; median age at graduation, 33.0 [IQR, 31.0-35.0 years]) in neurosurgery (n = 595), orthopedic surgery (n = 3481), and internal medicine (n = 41 669). In the first 2 years of independent practice, 95% (n = 3297), 92% (n = 546), and 59% (n = 24 522) of newly independent physicians in orthopedic surgery, neurosurgery, and internal medicine, respectively, accepted any general payments. A higher percentage of the newly independent physicians in orthopedic surgery and neurosurgery accepted any general payments (orthopedic surgery vs internal medicine: HR, 5.36 [95% CI, 4.42-6.51] for women and 7.01 [95% CI, 6.35-7.73] for men; neurosurgery vs internal medicine: HR, 3.25 [95% CI, 2.24-4.72] for women and 4.08 [95% CI, 3.37-4.94] for men; P = .03). A higher percentage of male physicians compared with female physicians accepted any general payments (orthopedic surgery, 2884 of 3026 [95%] vs 413 of 455 [91%]; P < .001; neurosurgery, 466 of 502 [93%] vs 80 of 93 [86%]; P = .01; and internal medicine, 15 462 of 24 609 [63%] vs 9043 of 17 034 [53%]; P < .001) and at least $5000 of general payments (orthopedic surgery, 763 of 3026 [25%] vs 71 of 455 [16%]; P < .001; neurosurgery, 87 of 502 [17%] vs 5 of 93 [5%%]; P < .001; and internal medicine, 882 of 24 609 [4%] vs 210 of 17 034 [1%]; P < .001). Conclusions and Relevance: In this cohort study of newly independent physicians in orthopedic surgery, neurosurgery, and internal medicine, the financial relationship with potential conflicts of interest between newly independent physicians and industry began to develop soon after training programs and continued to expand in the early years of newly independent physician practice. Newly independent physicians in surgical specialties and male physicians accepted significantly higher industry payments. Further studies are needed to evaluate whether modifiable factors are associated with the future outcome of newly independent physicians accepting general payments.

Treatment of thigh abscess caused by retroperitoneal perforation of cecal cancer: A case report.

Introduction and importance: Iliopsoas and iliacus abscesses are caused by hematogenous and lymphatic infections and the spread of inflammation in neighboring organs. A small number of cases have been reported in which inflammation spread not only within the iliopsoas muscle but also to the thigh. Here we report a case of retroperitoneal infiltration and perforation of cecal cancer that caused extensive abscess formation from the iliacus muscle to the thigh. Case presentation: An 80-year-old man who had undergone chemotherapy for cecal cancer had abdominal pain and right thigh pain without any particular attraction. CT images showed extensive abscess formation from the iliacus muscle to the subcutaneous part of the thigh due to retroperitoneal infiltration and perforation of cecal cancer. Ileocecal resection, colostomy, and retroperitoneal abscess drainage were performed for perforation of cecal cancer and pelvic abscess. Although the thigh was initially drained by a small incision, the infection did not heal. Extensive debridement and drainage were required for all of the contaminated areas, and after all the infection was completely cured. Clinical discussion: The optimal treatment for an abscess that has spread from the inguinal region to the thigh is unclear. In this case, active debridement and drainage of the infected area were effective and should have been done early. Conclusion: We believed that debridement and drainage should have been performed from the time of the first surgery not only by the small incision drainage but also for all of the contaminated areas when the infection had been widespread.

Expert consensus on the conceptual alignment of Accreditation Council for Graduate Medical Education competencies with patient outcomes after common vascular surgical procedures.

BACKGROUND: The quality and effectiveness of vascular surgery education should be evaluated based on patient care outcomes. To investigate predictive associations between trainee performance and subsequent patient outcomes, a critical first step is to determine the conceptual alignment of educational competencies with clinical outcomes in practice. We sought to generate expert consensus on the conceptual alignment of the Accreditation Council for Graduate Medical Education (ACGME) Vascular Surgery subcompetencies with patient care outcomes across different Vascular Quality Initiative (VQI) registries. METHODS: A national panel of vascular surgeons with expertise in both clinical care and education were recruited to participate in a modified Delphi expert consensus building process to map ACGME Vascular Surgery subcompetencies (educational markers of resident performance) to VQI clinical modules (patient outcomes). A master list of items for rating was created, including the 31 ACGME Vascular Surgery subcompetencies and 8 VQI clinical registries (endovascular abdominal aortic aneurysm repair, open abdominal aortic aneurysm, thoracic endovascular aortic repair, carotid endarterectomy, carotid artery stent, infrainguinal, suprainguinal, and peripheral vascular intervention). These items were entered into an iterative Delphi process. Positive consensus was reached when 75% or more of the participants ranked an item as mandatory. Intraclass correlations (ICCs) were used to evaluate consistency between experts for each Delphi round. RESULTS: A total of 13 experts who contributed to the development of the Vascular Surgery Milestones participated; 12 experts (92%) participated in both rounds of the Delphi process. Two rounds of Delphi were conducted, as suggested by excellent expert agreement (round 1, ICC = 0.79 [95% confidence interval, 0.74-0.84]; round 2, ICC = 0.97 [95% confidence interval, 0.960-.98]). Using the predetermined consensus cutoff threshold, the Delphi process reduced the number of subcompetencies mapped to patient care outcomes from 31 to a range of 9 to 15 across the 8 VQI clinical registries. Practice-based learning and improvement, and professionalism subcompetencies were identified as less relevant to patient outcome variables captured by the VQI registries after the final round, and the only the systems-based practice subcompetency that was identified as relevant was radiation safety in two of the endovascular registries. CONCLUSIONS: A national panel of vascular surgeon experts reported a high degree of agreement on the relevance of ACGME subcompetencies to patient care outcomes as captured in the VQI clinical registry. Systems-based practice, practice-based learning and improvement, and professionalism competencies were identified as less relevant to patient outcomes after specific surgical procedures.

Evaluating the burden of the COVID-19 pandemic on patients with colorectal cancer.

After the emergence of the coronavirus disease 2019 (COVID-19) pandemic, individuals needing medical help preferred to not go to the hospital to avoid the risk of severe acute respiratory syndrome coronavirus 2 infection. The present study investigated the influence of the COVID-19 pandemic on patients with colorectal cancer. Patients with colorectal cancer treated between January and December 2019 were classified as the pre-pandemic group (pre-group) and those treated between April 2020 and March 2021 as the post-pandemic group (pandemic group). The clinicopathologic features of patients who underwent surgery for colorectal cancer in the two groups were retrospectively compared. A total of 161 patients were enrolled: 79 In the pre-group and 82 in the pandemic group. Although no significant differences were observed in tumor location and surgical procedure between the two groups, circumferential lesions (P<0.001), colorectal stenting (P=0.016) and Stage IV classification (P=0.019) had a higher frequency in the pandemic group compared with the pre-group; additionally, surgical curability was significantly lower (P=0.036) in the pandemic group. The spread of COVID-19 has increased the incidence of patients with advanced colorectal cancer. To reduce this incidence, healthcare professionals should inform the general public not only about the risk of COVID-19, but also about the increased incidence of advanced colorectal cancer after the pandemic.

[Successful Surgical Correction of Partial Atrioventricular Septal Defect in an Elderly Patient:Report of a Case].

There are only few reports on surgery for partial atrioventricular septal defect( pAVSD) in patients aged over 70 years. This report is about successful surgical correction of pAVSD in a 79-year-old women. Echocardiography showed left-sided atrioventricular valve regurgitation with cleft and ostium primum atrial septal defect, but without ventricular septal defect. Accordingly, she was diagnosed with pAVSD. Treatment plan included direct cleft closure, patch closure for the ostium primum atrial septal defect, and right atrioventricular annuloplasty. The postoperative course was uneventful. She was followed up without complications for four years. To the best of our knowledge, our patient is the oldest to undergo such surgical techniques in Japan to date.

Efficacy of polyglycolic acid sheeting with fibrin glue for perforations related to gastrointestinal endoscopic procedures: a multicenter retrospective cohort study.

OBJECTIVES: Gastrointestinal (GI) perforations are one of the major adverse events of endoscopic procedures. Polyglycolic acid (PGA) sheets with fibrin glue have been reported to close GI perforations. However, its clinical outcome has not yet been fully investigated; thus, we conducted a multicenter retrospective observational study to assess the efficacy of PGA sheeting for GI perforation. METHODS: The medical records of patients who underwent PGA sheeting for endoscopic GI perforations between April 2013 and March 2018 in 18 Japanese institutions were retrospectively analyzed. PGA sheeting was applied when the clip closure was challenging or failed to use. Perforations were filled with one or several pieces of PGA sheets followed by fibrin glue application through an endoscopic catheter. Nasal or percutaneous drainage and endoscopic clipping were applied as appropriate. Clinical outcomes after PGA sheeting for intraoperative or delayed perforations were separately evaluated. RESULTS: There were 66 intraoperative and 24 delayed perforation cases. In intraoperative cases, successful closure was attained in 60 cases (91%). The median period from the first sheeting to diet resumption was 6 days (interquartile range [IQR], 4-8.8 days). Large perforation size (≥ 10 mm) and duodenal location showed marginal significant relationship to higher closure failure of intraoperative perforations. In delayed perforation cases, all cases had successful closure. The median period from the first sheeting to diet resumption was 10 days (IQR, 6-37.8 days). No adverse events related to PGA sheeting occurred. CONCLUSION: Endoscopic PGA sheeting could be a therapeutic option for GI perforations related to GI endoscopic procedures.
