General Surgery Education Across Three Continents

Surgical education has seen tremendous changes in the US over the past decade. The Halstedian training model of see one, do one, teach one that governed surgical training for almost 100 years has been replaced by the achievement of the ACGME competencies, milestones, entrustable professional activities (EPAs), and acquisition of surgical skill outside the operating room on simulators. Several of these changes in American medical education have been influenced by educators and training paradigms abroad. In this paper, we review the training paradigms for surgeons in the UK, Japan, and Mexico to allow comparisons with the US training paradigm and promote the exchange of ideas

Successful recovery from a subclavicular ulcer caused by lenvatinib for thyroid cancer: a case report

Background: There are currently no effective therapeutic methods for locally recurrent, metastatic, or progressive radioactive iodine (RAI)-refractory differentiated thyroid cancer. However, multitargeted tyrosine kinase inhibitors (TKIs) such as lenvatinib or sorafenib have been approved for patients with RAI-refractory differentiated thyroid cancer as a second targeted therapy, and these agents can prolong patient survival. However, several cases have been reported that TKIs have caused fatal complications such as fistula formation or bleeding. Case presentation: We report a case of a 53-year-old woman, who underwent repeated neck dissections and RAI therapy after total thyroidectomy in an outside hospital. Pathology revealed a papillary carcinoma of the tall cell variant. Locoregional recurrence was not under control; therefore, she visited our hospital. Although surgery was performed for locoregional recurrences three times in our hospital, they were not under control and distant metastases were found in the lung and bone a year later. Therefore, although sorafenib was initiated, the locoregional recurrence progressed 6months later and computed tomography (CT) showed a 7-cm mass in the right subclavicular lesion. Lenvatinib was started at a dose of 24mg daily. However, although tumor was rapidly reduced, an ulcer occurred in the right subclavicular lesion and was gradually increasing in size. The pulsation of subclavicular artery was found in the deep portion of the ulcer. Therefore, a pectoralis major myocutaneous flap was transplanted to cover the ulcer. Lenvatinib was an antiangiogetic TKI; therefore, it was preoperatively discontinued for 8days and postoperatively for 12days. The postoperative course was uneventful. Conclusions: Fistula formation or bleeding is known to be a severe side effect of antiangiogenic TKIs such as lenvatinib or sorafenib. There is a possibility that severe complications can occur when initiating TKIs in patients whose tumor has invaded into the skin, vessels, trachea, esophagus, and other areas. Therefore, it is necessary to use antiangiogenic TKIs very carefully. It is important to determine the appropriate time to start TKIs; however, there is no established protocol for this, and it is a problem that needs urgent attention

Surgical assessment system reflexes and facilitates the developing the surgical skills of trainees for the Laparoscopic Distal Gastrectomy

Background: To assess laparoscopic distal gastrectomy (LDG) for gastric cancer (GC), the Japanese Operative Rating Scale (JORS) for LDG has been developed. This study evaluated the learning curve of the initial experience of LDG for GC using JORS-LDG.Methods: Thirty-one cases of LDG were performed by a trainee. The trainee and an instructor scored the surgical performance using JORS-LDG immediately after LDG. The 31 cases were evenly divided into early phase (EP), middle phase (MP), and late phase (LP).Results: The trainee successfully completed all cases of LDG without any complications. There were also no severe postoperative complications with Clavien–Dindo classification grade III or higher. The average JORS-LDG points were stable after 24 cases of experience in the CUSUM analysis. The median JORS-LDG points in EP were significantly lower than those in LP (EP: MP: LP = 43.5: 44.3: 45.5, P = 0.02). In operative data, procedure time, bleeding, and the drain fluid amylase level were correlated with the JORS-LDG points.Conclusion: The JORS-LDG scoring system is a practical tool to evaluate surgical performance in the initial LDG experience

Interleukin 6 in autoimmune and inflammatory diseases: a personal memoir

In this review, the author discusses the research that led to the identification and characterization of interleukin 6 (IL-6), including his own experience isolating IL-6, and the roles this cytokine has on autoimmune and inflammatory diseases. The cDNAs encoding B-cell stimulatory factor 2 (BSF-2), interferon (IFN)-β2 and a 26-kDa protein were independently cloned in 1986, which in turn led to the identification of each. To resolve the confusing nomenclature, these identical molecules were named IL-6. Characterization of IL-6 revealed a multifunctional cytokine that is involved in not only immune responses but also hematopoiesis, inflammation, and bone metabolism. Moreover, IL-6 makes significant contributions to such autoimmune and inflammatory diseases as rheumatoid arthritis (RA)

Associations of Glucose and Blood Pressure Variability with Cardiac Diastolic Function in Patients with Type 2 Diabetes Mellitus and Hypertension: A Retrospective Observational Study

We evaluated the effects of glucose metabolism and blood pressure（BP） variability on cardiac diastolic function in patients with type 2 diabetes mellitus（T2DM） and hypertension. A total of 23 inpatients with T2DM underwent ambulatory BP monitoring（ABPM） and echocardiography. BP variability was assessed by measuring the mean BP and the standard deviation（SD） of systolic and diastolic BP over 24 hours, as well as daytime and nighttime ABPM. Cardiac diastolic function was assessed using the echocardiography E/e′ ratio. Participants had a mean age of 69.0±10.6 years, disease duration of 11.0±10.5 years, glycated hemoglobin（HbA1c） of 8.2％±1.3％, and glycated albumin（GA） of 22.0％±4.2％. Univariate analysis showed that the nighttime systolic BP, nighttime SDs of systolic and diastolic BP, urinary albumin, estimated glomerular filtration rate, and GA/HbA1c ratio were all significantly correlated with the E/e′ ratio. Moreover, stepwise multiple regression analysis identified nighttime SD of diastolic BP, urinary albumin, and GA/HbA1c ratio as independent contributors to the E/e′ ratio. In patients with T2DM and hypertension, cardiac diastolic function was associated with nighttime diastolic BP variability and the GA/HbA1c ratio

Delphi Method Consensus-Based Identification of Primary Trauma Care Skills Required for General Surgeons in Japan

Purpose General surgeons at regional hospitals should have the primary trauma care skills necessary to treat critically ill trauma patients to withstand transfer. This study was conducted to identify a consensus on primary trauma care skills for general surgeons. Methods An initial list of acute care surgical skills was compiled, and revised by six trauma experts (acute care surgeons); 33 skills were nominated for inclusion in the Delphi consensus survey. Participants (councilors of the Japanese Society for Acute Care Surgery) were presented with the list of 33 trauma care skills and were asked (using web-based software) to rate how strongly they agreed or disagreed (using a 5-point Likert scale) with the necessity of each skill for a general surgeon. The reliability of consensus was predefined as Cronbach’s α ≥ 0.8, and trauma care skills were considered as primarily required when rated 4 (agree) or 5 (strongly agree) by ≥ 80% participants. Results There were 117 trauma care specialists contacted to participate in the Delphi consensus survey panel. In the 1st round, 85 specialists participated (response rate: 72.6%). In the 2nd round, 66 specialists participated (response rate: 77.6%). Consensus was achieved after two rounds, reliability using Cronbach’s α was 0.94, and 34 items were identified as primary trauma care skills needed by general surgeons. Conclusion A consensus-based list of trauma care skills required by general surgeons was developed. This list can facilitate the development of a new trauma training course which has been optimized for general surgeons
