Background
This study aimed to identify differences in pattern recognition skill among individuals with varying surgical experience.Methods
Participants reviewed laparoscopic cholecystectomy videos of various difficulty, and paused them when the cystic duct or artery was identified to outline each structure on the monitor. Time taken to identify each structure, accuracy and work load, which was assessed using the NASA-Task Load Index (TLX), were compared among the three groups.Results
Ten students, ten residents and eight attendings participated in the study. Attendings identified the cystic duct and artery significantly faster and more accurately than students, and identified the cystic artery faster than residents. The NASA-TLX score of attendings was significantly lower than that of students and residents.Conclusions
Attendings identified anatomical structures faster, more accurately, and with less effort than students or residents. This platform may be valuable for the assessment and teaching of pattern recognition skill to novice surgeons.Short summary
Accurate anatomical recognition is paramount to proceeding safely in surgery. The assessment platform used in this study differentiated recognition skill among individuals with varing surgical experience. 相似文献2.

Background
Emergency surgical airway is a low frequency, high risk clinical scenario. Implementing a simulation-based curriculum may bridge the gap in surgical training and address quality assurance/performance improvement (QAPI) needs.Methods
We designed and implemented an Advanced Surgical Airway Curriculum (ASAC) modeled after proficiency-based training. General Surgery residents and student nurse anesthetists were enrolled. Evaluation consisted of cognitive tests, procedure checklists and questionnaire.Results
In total, 78 participants successfully completed the ASAC. Trainees agreed that the curriculum provided the cognitive and psychomotor skills necessary to perform both an open and needle cricothyroidotomy.Conclusions
In the age of increased patient safety concerns, QAPI initiatives can serve as a driver for simulation-based training curricula, with particular focus on individualized, active learning. This may be particularly useful in high risk, low frequency scenarios in which the traditional method of “See one, Do one, Teach one,” is not feasible. 相似文献3.

Objective
We incorporated a hybrid-abdominal wound simulation to teach/assess the acquisition of three essential clinical skills in the ACS/ASE Medical Student Simulation-based Surgical Skills Curriculum.Method
Third year students (N?=?43) attended a workshop based on the ACS/ASE surgical skills curriculum for drain care/removal, staple removal and Steri-Strip application. Following a didactic session and demonstration using a simulated patient, student skill acquisition was assessed using the ACS/ASE module rating tool. Student interest/perceived usefulness of the workshop was evaluated using Keller's Motivational Survey.Results
We used median scores to identify low proficiency (n?=?20; scores 17–28) and high proficiency (n?=?23; scores 29–35) groups. The high proficiency group was more knowledgeable, performed better drain care, had a higher global score and was more confident than the low proficiency group. The students rated the workshop highly based on the Keller's Motivational Survey.Conclusion
All students were proficient in the procedure tasks and communication skills and most felt that the course was beneficial. The ACS/ASE Medical Student Simulation-based Surgical Skills Curriculum was successfully integrated into our third year surgical clerkship. 相似文献6.

Basic research (biomechanics).Introduction
The high degree of motion that occurs at the thumb metacarpophalangeal (MCP) joint must be taken into account when immobilizing a partially torn or repaired thumb ulnar collateral ligament.Purpose of the Study
To determine the efficacy of a radial-based thumb MCP-stabilizing orthosis in resisting abduction across the thumb ulnar collateral ligament.Methods
Ten fresh cadaveric hands were mounted to a custom board. An anteroposterior radiograph of the thumb was obtained with a 2 N preload valgus force applied to the thumb, and the angle between the Kirschner wires was measured as a baseline. Subsequently, 20, 40, 60, 80, and 100 N valgus forces were applied 15 mm distal to the MCP joint. Anteroposterior radiographs of the thumb were obtained after each force was applied. The angle of displacement between the wires was measured and compared with the baseline angle. The angles were measured with an imaging processing tool. A custom radial-based thumb MCP-stabilizing orthosis was fashioned for each cadaveric thumb by a certified hand therapist. The aforementioned loading protocol was then repeated.Results
The radial-based thumb MCP-stabilizing orthosis significantly reduced mean abduction angles at each applied load.Discussion
We found that our orthosis, despite being hand-based and leaving the thumb IP and CMC joints free, significantly reduced mean abduction angles at each applied load.Conclusions
This investigation provides objective evidence that our radial-based thumb MCP-stabilizing orthosis effectively reduces the degree of abduction that occurs at the thumb MCP joint up to at least 100 N.Level of Evidence

Case series.Introduction
A salvaged limb is one that has undergone a major traumatic injury, followed by repeated surgical attempts in order to avoid amputation. Psychological recovery for individuals with lower extremity limb salvage has been examined in a number of studies. However, psychosocial reactions for individuals with upper extremity (UE) limb salvage are understudied in the literature.Purpose of the Study
The purpose of this study was to explore the process of psychosocial adaptation for 3 trauma cases after UE limb salvage.Methods
The Reactions to Impairment and Disability Inventory was used to assess psychosocial adaptation. Physical function outcomes (pain, range of motion, edema, sensation, and dexterity) are presented. The Disabilities of the Arm, Shoulder, and Hand measure was used to assess perceived disability. Medical and rehabilitation history are discussed for each case, in order to provide in-depth understanding of the impact of these injuries.Results
Reactions to injury varied across the cases; however, outcomes suggest that psychosocial adaptation may be influenced by the experience of pain, the ability to participate in valued roles and activities, and having a supportive social network.Discussion
For this population, therapists may consider emphasizing pain management, focusing on client-centered goals and interventions, and facilitating peer support. Providers should closely monitor patients for signs of poor adaptation, such as hand-hiding behaviors.Conclusions
This study is among the first to examine psychological outcomes for the UE limb salvage population. Future research would be beneficial to provide deeper understanding of the psychosocial challenges for these individuals. 相似文献8.

Background
Robotic surgery is increasingly adopted into surgical practice, but it remains unclear what level of robotic training general surgery residents receive. The purpose of our study was to assess the variation in robotic surgery training amongst general surgery residency programs in the United States.Methods
A web-based survey was sent to 277 general surgery residency programs to determine characteristics of resident experience and training in robotic surgery.Results
A total of 114 (41%) programs responded. 92% (n?=?105) have residents participating in robotic surgeries; 68%(n?=?71) of which have a robotics curriculum, 44%(n?=?46) track residents’ robotic experience, and 55%(n?=?58) offer formal recognition of training completion. Responses from university-affiliated (n?=?83) and independent (n?=?31) programs were not significantly different.Conclusions
Many general surgery residencies offer robotic surgery experience, but vary widely in requisite components, formal credentialing, and case tracking. There is a need to adopt a standardized training curriculum and document resident competency. 相似文献9.

Background
Adhesive bowel obstruction is associated with considerable morbidity and mortality, but the magnitude of the risk is debated.Method
In a national cohort of all Danish women with an abdominal operation (N?=?665,423) between 1977 and 2013, the risk of adhesive bowel obstruction was assessed by Cox multiple regression. Covariates were the number of abdominal operations, the surgical methods, the anatomical site involved, and the calendar year.Results
In the cohort, 1.4% experienced an episode of adhesive bowel obstruction. The risk increased 33–43% during the study period, was lower after gynecological and obstetrical procedures compared to gastrointestinal (HR 0.36 [0.34–0.38]), lower after laparoscopic compared to laparotomic surgery (HR 0.51 [0.48–0.54]) and increased proportionally after each additional operation.Conclusions
The risk of adhesive bowel obstruction after abdominal operations depends on the site of earlier operations, the method of access and the number of earlier operations. 相似文献10.

Introduction
Several studies demonstrated that simulator-acquired skill transfer to the operating room is incomplete. Our objective was to identify trainee characteristics that predict the transfer of simulator-acquired skill to the operating room.Methods
Trainees completed baseline assessments including intracorporeal suturing (IS) performance, attentional selectivity, self-reported use of mental skills, and self-reported prior clinical and simulated laparoscopic experience and confidence. Residents then followed proficiency-based laparoscopic skills training, and their skill transfer was assessed on a live-anesthetized porcine model. Predictive characteristics for transfer test performance were assessed using multiple linear regression.Results
Thirty-eight residents completed the study. Automaticity, attentional selectivity, resident perceived ability with laparoscopy and simulators, and post-training IS performance were predictive of IS performance during the transfer test.Conclusions
Promoting automaticity, self-efficacy, and attention selectivity may help improve the transfer of simulator-acquired skill. Mental skills training and training to automaticity may therefore be valuable interventions to achieve this goal. 相似文献11.

Objectives
Structural valve deterioration (SVD) remains a major bioprosthesis-related complication, as recently described for the Mitroflow valve (models LX and 12A) (LivaNova, London, United Kingdom). The real incidence of the SVD risk remains unclear, often due to methodologic pitfalls by systematically using the Kaplan-Meier estimator and/or the Cox model. In this report, we propose for the first time a precise statistical modeling of this issue.Methods
Five hundred sixty-one patients who underwent aortic valve replacement with the aortic Mitroflow valve between 2002 and 2007 were included. We used an illness–death model for interval-censored data. Median follow-up was 6.6 years; 103 cases of SVD were diagnosed.Results
The 4-year and 7-year SVD cumulative incidences after the first anniversary of surgery were 15.2% (95% confidence interval, 11.9-19.1) and 31.0% (95% confidence interval, 25.8-37.2), respectively. Female gender, dyslipidemia, chronic obstructive pulmonary disease, and severe patient-prosthesis mismatch were significant risk factors of SVD. The occurrence of SVD was associated with a 2-fold increase in the risk of death.Conclusions
Appropriate statistical models should be used to avoid underestimating the SVD complication associated with worse long-term survival. 相似文献12.

Two-group randomized controlled trial.Introduction
Upper limb orthoses worn during functional tasks are commonly used in pediatric neurologic rehabilitation, despite a paucity of high-level evidence.Purpose of the Study
The purpose of this study was to investigate if a customized functional wrist orthosis, when placed on the limb, leads to an immediate improvement in hand function for children with cerebral palsy or brain injury.Methods
A 2-group randomized controlled trial involving 30 children was conducted. Participants were randomized to either receive a customized functional wrist orthosis (experimental, n = 15) or not receive an orthosis (control, n = 15). The box and blocks test was administered at baseline and repeated 1 hour after experimental intervention, with the orthosis on if randomized to the orthotic group.Results
After intervention, there were no significant differences on the box and blocks test between the orthotic group (mean, 10.13; standard deviation, 11.476) and the no orthotic group (mean, 14.07; standard deviation, 11.106; t[28], ?0.954; P = .348; and 95% confidence interval, ?12.380 to 4.513).Discussion
In contrast to the findings of previous studies, our results suggest that a functional wrist orthosis, when supporting the joint in a ‘typical’ position, may not lead to an immediate improvement in hand function.Conclusions
Wearing a functional wrist orthosis did not lead to an immediate improvement in the ability of children with cerebral palsy or brain injury to grasp and release. Further research is needed combining upper limb orthoses with task-specific training and measuring outcomes over the medium to long term. 相似文献13.

Background
We hypothesized that medical experts would concur the American College of Surgeons/Association for Surgical Education Medical Student Simulation-based Surgical Skills Curriculum (“ACS/ASE Curriculum”) could be used to teach and assess Entrustable Professional Activities (EPAs).Methods
A “crosswalk” was created between ACS/ASE Curriculum modules and eight EPAs. Medical education experts participated in a Delphi process regarding feasibility of using the modules for teaching and assessing EPAs.Results
Twenty-eight educators from six clinical fields participated. There was consensus that five of the EPAs could be taught and assessed by the ACS/ASE Curriculum. A median of nine hours per month outside the surgical clerkship was recommended for skills training.Conclusions
The ACS/ASE Curriculum lays the framework for implementing select EPAs into medical student education. Experts recommended increased time for skills training with incorporation of the modules into the first three years of medical education, with assessments planned in the third to fourth years. 相似文献14.

Case series.Introduction
Upper extremity (UE) trauma and subsequent immobilization affects functional performance.Purpose of the Study
Determine the usefulness and feasibility of unilateral hand training (UHT) on improving functional performance in patients with UE trauma.Methods
Nine participants received UHT within 10 days of immobilization. Functional performance, dexterity, grip, and pinch strength were measured at initial and 4-week visits. Qualitative interviews were coded to develop themes.Results
All Jebsen-Taylor hand function test subtests improved from pretest to post-test. Disabilities of the Arm, Shoulder and Hand scores of all 9 participants improved. Functional performance was more impaired for participants with dominant UE injury. Four themes emerged: participants were forced to alter or avoid most daily activities, had an increased dependency on others, took longer to perform activities, and felt UHT decreased the impact of UE trauma on function.Discussion
Functional performance was impaired for all participants. Participants believed that UHT was useful and contributed to improved function.Conclusion
This case series tracked a comprehensive intervention based on a holistic activities of daily living framework that considered the nuances of individual complexities of immobilization following hand trauma. Knowledge from this study supports an early intervention like UHT to educate clients on effective strategies to improve immediate activities of daily living functioning and potentially prevent longer term impairments. 相似文献15.

Introduction
The aim of this study was to determine whether complications following mastectomy with immediate breast reconstruction (IBR) were associated with breast cancer recurrence.Methods
A retrospective review was performed of women diagnosed with stage I-III breast cancer who underwent mastectomy with IBR between 2005 and 2010. Patient demographics, tumor data, surgical wound complications, treatment details and timing were recorded and analyzed.Results
We identified 458 women with a median follow up time of 7.6 years. A total of 22% of patients experienced IBR complications. There was a delay in initiation of adjuvant therapy in patients who had a complication (52 vs 41 days, p?<?0.001). There was no significant difference in recurrences between groups with and without complications (p?=?0.65).Conclusions
In breast cancer patients who undergo mastectomy with IBR, wound complications delayed initiation of adjuvant systemic therapy, but were not associated with an increased risk of cancer recurrence. 相似文献16.

Background
There are notable disparities in the training, recruitment, promotion, and evaluation of men and women in surgery. The qualitative assessment of surgical residents may be implicitly gender biased.Methods
We used inductive analysis to identify themes in written evaluations of residents. We also performed a content analysis of words fitting previously defined communal, grindstone, ability, and standout categories.Results
Differences in themes that emerged from evaluations of male and female residents were notable regarding overall performance, references to the future, professional competency, job domains, disposition and humanism, and overall tone of evaluations. Comments about men were more positive than those about women, and evaluations of men included more standout words.Conclusions
The more positive evaluations of men may handicap women if they are seen as less likely to perform well based on these evaluations. These differences suggest that implicit bias may play a role in the qualitative evaluation of surgical residents. 相似文献17.

Background
This study examines the alignment of quantitative and qualitative assessment data in end-of-rotation evaluations using longitudinal cohorts of residents progressing throughout the five-year general surgery residency.Methods
Rotation evaluation data were extracted for 171 residents who trained between July 2011 and July 2016. Data included 6069 rotation evaluations forms completed by 38 faculty members and 164 peer-residents. Qualitative comments mapped to general surgery milestones were coded for positive/negative feedback and relevance.Results
Quantitative evaluation scores were significantly correlated with positive/negative feedback, r?=?0.52 and relevance, r?=??0.20, p?<?.001. Themes included feedback on leadership, teaching contribution, medical knowledge, work ethic, patient-care, and ability to work in a team-based setting. Faculty comments focused on technical and clinical abilities; comments from peers focused on professionalism and interpersonal relationships.Conclusions
We found differences in themes emphasized as residents progressed. These findings underscore improving our understanding of how faculty synthesize assessment data. 相似文献18.

Clinical measurement study.Introduction
The push-off test (POT) was recently conceived and found to be reliable and valid for assessing weight bearing through injured wrist or elbow. However, further research with larger sample can lend credence to the preliminary findings supporting the use of the POT.Purpose of the Study
This study examined the interrater reliability, construct validity, and measurement error for the POT in patients with wrist conditions.Methods
Participants with musculoskeletal (MSK) wrist conditions were recruited. The performance on the POT, grip isometric strength of wrist extensors was assessed. The shortened version of the Disabilities of the Arm, Shoulder and Hand and numeric pain rating scale were completed. The intraclass correlation coefficient assessed interrater reliability of the POT. Pearson correlation coefficients (r) examined the concurrent relationships between the POT and other measures. The standard error of measurement and the minimal detectable change at 90% confidence interval were assessed as measurement error and index of true change for the POT.Results
A total of 50 participants with different elbow or wrist conditions (age: 48.1 ± 16.6 years) were included in this study. The results of this study strongly supported the interrater reliability (intraclass correlation coefficient: 0.96 and 0.93 for the affected and unaffected sides, respectively) of the POT in patients with wrist MSK conditions. The POT showed convergent relationships with the grip strength on the injured side (r = 0.89) and the wrist extensor strength (r = 0.7). The POT showed smaller standard error of measurement (1.9 kg). The minimal detectable change at 90% confidence interval for the POT was 4.4 kg for the sample.Conclusions
This study provides additional evidence to support the reliability and validity of the POT. This is the first study that provides the values for the measurement error and true change on the POT scores in patients with wrist MSK conditions. Further research should examine the responsiveness and discriminant validity of the POT in patients with wrist conditions. 相似文献19.
