Using Concurrent Complication Reporting to Evaluate Resident Critical Thinking and Enhance Adult Learning.

OBJECTIVE: Critical thinking and accurate case analysis is difficult to quantify even within the context of routine morbidity and mortality reporting. We designed and implemented a HIPAA-compliant adverse outcome reporting system that collects weekly resident assessments of clinical care across multiple domains (case summary, complications, error analysis, Clavien-Dindo Harm, cognitive bias, standard of care, and ACGME core competencies). We hypothesized that incorporation of this system into the residency program's core curriculum would allow for identification of areas of cognitive weakness or strength and provide a longitudinal evaluation of critical thinking development. DESIGN: A validated, password-protected electronic platform linked to our electronic medical record was used to collect cases weekly in which surgical adverse events occurred. General surgery residents critiqued 1932 cases over a 4-year period from 3 major medical centers within our system. These data were reviewed by teaching faculty, corrected for accuracy and graded utilizing the software's critique algorithm. Grades were emailed to the residents at the time of the review, collected prospectively, stratified, and analyzed by post-graduate year (PGY). Evaluation of the resident scores for each domain and the resultant composite scores allowed for comparison of critical thinking skills across post-graduate year (PGY) over time. SETTING: Data was collected from 3 independently ACGME-accredited surgery residency programs over 3 tertiary hospitals within our health system. PARTICIPANTS: General surgery residents in clinical PGY 1-5. RESULTS: Residents scored highest in properly identifying ACGME core competencies and determining Clavien-Dindo scores (p < 0.006) with no improvement in providing accurate and concise clinical summaries. However, residents improved in recording data sufficient to identify error (p < 0.00001). A positive linear trend in median scores for all remaining domains except for cognitive bias was demonstrated (p < 0.001). Senior residents scored significantly higher than junior residents in all domains. Scores > 90% were never achieved. CONCLUSIONS: The use of an electronic standardized critique algorithm in the evaluation and assessment of adverse surgical case outcomes enabled the measure of residents' critical thinking skills. Feedback in the form of teaching faculty-facilitated discussion and emailed grades enhanced adult learning with a steady improvement in performance over PGY. Although residents improved with PGY, the data suggest that further improvement in all categories is possible. Implementing this standardized critique algorithm across PGY allows for evaluation of areas of individual resident weakness vs. strength, progression over time, and comparisons to peers. These data suggest that routine complication reporting may be enhanced as a critical thinking assessment tool and that improvement in critical thinking can be quantified. Incorporation of this platform into M&M conference has the potential to augment executive function and professional identity development.

Outcome prediction in bariatric surgery through video-based assessment.

INTRODUCTION: The relationship between intraoperative surgical performance scores and patient outcomes has not been demonstrated at a single-case level. The GEARS score is a Likert-based scale that quantifies robotic surgical proficiency in 5 domains. Given that even highly skilled surgeons can have variability in their skill among their cases, we hypothesized that at a patient level, higher surgical skill as determined by the GEARS score will predict individual patient outcomes. METHODS: Patients undergoing robotic sleeve gastrectomy between July 2018 and January 2021 at a single-health care system were captured in a prospective database. Bivariate Pearson's correlation was used to compare continuous variables, one-way ANOVA for categorical variables compared with a continuous variable, and chi-square for two categorical variables. Significant variables in the univariable screen were included in a multivariable linear regression model. Two-tailed p-value < 0.05 was considered significant. RESULTS: Of 162 patients included, 9 patients (5.5%) experienced a serious morbidity within 30 days. The average excess weight loss (EWL) was 72 ± 12% at 6 months and 74 ± 15% at 12 months. GEARS score was not significantly correlated with EWL at 6 months (p = 0.349), 12 months (p = 0.468), or serious morbidity (p = 0.848) on unadjusted analysis. After adjusting, total GEARS score was not correlated with serious morbidity (p = 0.914); however, GEARS score did predict EWL at 6 (p < 0.001) and 12 months (p < 0.001). All GEARS subcomponent scores, bimanual dexterity, depth perception, efficiency, force sensitivity, and robotic control were predictive of EWL at 6 months (p < 0.001) and 12 months (p < 0.001) on multivariable analysis. CONCLUSION: For patients undergoing sleeve gastrectomy, surgical skill as assessed by the GEARS score was correlated with EWL, suggesting that better performance of a sleeve gastrectomy can result in improved postoperative weight loss.

Hypoglycemia and Dysautonomia After Bariatric Surgery: a Systematic Review and Perspective.

INTRODUCTION: With the increasing performance of bariatric surgery, rare complications are becoming prevalent. We review the diagnosis and treatment of dysautonomia after bariatric surgery and the limited treatment options available. We summarize the suggested mechanisms and explain why a complete understanding of the etiology has yet to be determined. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review was performed. RESULTS: Of 448 studies identified in the literature search, 4 studies were reviewed, describing 87 patients diagnosed with dysautonomia. We present a patient who developed severe dysautonomia following conversion of sleeve gastrectomy to gastric bypass. CONCLUSION: Treatment needs to focus on optimizing nutrition, avoiding hypoglycemia, and optimizing volume status.

A Nerve of McKenzie With a Variant Communicating Branch Between the Vagus Nerve and Cranial Root of the Accessory Nerve: A Cadaveric Case Report.

Anatomical variations of the craniocervical junction including a nerve of McKenzie, a branch between the spinal accessory nerve (XI) and the ventral root of the first cervical nerve (C1), have been identified. During routine dissection, a nerve of McKenzie with an interneural connection between the cranial root of the accessory nerve and the vagus nerve was observed on the left side. To our knowledge, a case with these two anatomical variations in the same cadaver and on the same side has not previously been reported. These variants may complicate surgery of the nerves of the craniocervical junction, and should thus be appreciated by the surgeon. Here, we discuss this case, its possible embryological origins, and the clinical significance.

Case of simultaneous Chiari 1.5 malformation and syringobulbia.

Chiari 1.5 malformation (C1.5) is a rare condition characterized by caudal descent of the brain stem, together with descent of the cerebellar tonsils characteristic of Chiari I malformation (CIM). Syringobulbia (SB) is rarely associated with CIM and to date has not been reported in a patient with C1.5. An adolescent female presented with Valsalva-induced headaches and a left abducens nerve palsy. Imaging revealed C1.5 and a huge syringomyelia extending cranially into the herniated medulla oblongata as syringobulbia. Simultaneous cases of C1.5 and syringomyelia (SM) have been described, but, to our knowledge, this is the first reported case of simultaneous C1.5 and SB. As SB can have life altering consequences, the clinician should keep this possibility in their differential diagnosis.

Adult Pineal Region Atypical Teratoid Rhabdoid Tumor: A Case for Aggressive Surgical and Chemoradiation Management with Comprehensive Literature Review.

BACKGROUND: Atypical teratoid rhabdoid tumor (ATRT) is a rare, highly malignant central nervous system neoplasm classified as an embryonal grade IV neoplasm by the World Health Organization. ATRT generally occurs in children younger than 3 years, with 85 pathologically confirmed cases reported in adults. It is most commonly supratentorial, with only 9 confirmed adult cases localized to the pineal region. CASE DESCRIPTION: The case is described of a 29-year-old man with a history of chronic migraines and a previously negative computed tomography scan of the head presenting with worsening headaches and new-onset diplopia with upward gaze palsy. Computed tomography and magnetic resonance imaging showed a hemorrhagic pineal mass with extension into the right thalamus. After resection, the immunohistochemical staining and cytogenetic profile proved consistent with ATRT, making it the ninth reported case of pineal ATRT in an adult, which was treated aggressively with good outcome. CONCLUSIONS: Adult ATRT is rare, especially in the pineal region, with only 9 cases reported. Because of the aggressiveness, ATRT must be considered in the differential diagnosis of pineal region lesions because early diagnosis and aggressive treatment are key to prolonged survival.
