ABSTRACT Introduction The American Association of Endocrine Surgeons (AAES) drafted Entrustable Professional Activities (EPAs) for Endocrine Surgery (ES) to assess general surgery residents and ES fellows in core topics. Here, we examine learner and teacher concordance of entrustability ratings. Methods Fourteen EPAs were defined (10 “core”–6 with pre‐, intra‐, and post‐operative phases, four single‐phase–and four elective EPAs). Ten institutions collected three‐item micro‐assessments (MAs) of learner EPA performance using a web‐based platform, where entrustment was assessed on observable behaviors using a five‐point scale. Learner provided self‐assessment ratings, while teachers separately assigned ratings for the same activities. Spearman rank correlation tests were applied to compare learner‐teacher ratings for EPAs. Results MAs ( n = 698) were submitted between 7/2022‐9/2023. Programs submitted between 3 and 468 MAs. Among 3‐phase core EPAs, the intraoperative phase was most assessed ( n = 496), followed by pre‐ and post‐operative phases ( n = 108 and 55, respectively). Thirty‐nine single‐phase EPAs were submitted. Learner self‐assessment and teacher ratings were equivalent for 32% of pre‐operative EPAs, 53% of intra‐operative EPAs, 29% of post‐operative EPAs, and 64% of single phase of care EPAs. Spearman rank correlation between teacher and learner ratings for all phases of care combined was 0.66. Correlation was highest for the intra‐operative phase (0.73), followed by single‐phase (0.65), pre‐operative phase (0.27), and post‐operative phase (0.20). Rating concordance did not differ when high and low scores were examined independently. Learners were more prone to underestimate performance than to overestimate it when ratings were discordant. Conclusions Learners' self‐assessment and teacher ratings of endocrine surgery EPAs are strongly concordant with operative technical skills. However, learners often underestimate their performance of pre‐ and post‐operative care compared to faculty ratings when using EPAs.

ABSTRACTIntroductionThe outcomes of completion thyroidectomy are not well‐documented. The study aim is to compare the risks of total thyroidectomy (TT), thyroid lobectomy (TL), and completion thyroidectomy (CT) using a large multi‐institutional database.MethodsAll cases of thyroidectomy without lymphadenectomy were identified using the CESQIP national database (2013–2023). Completion thyroidectomy was defined as contralateral lobectomy following previous lobectomy. Outcomes were examined including hematoma requiring evacuation, vocal cord dysfunction on post‐op laryngoscopy, and clinical concern for hypoparathyroidism.ResultsAmong 33,154 cases, TT, TL, and CT were performed in 19,057 (57%), 13,135 (40%) and 962 (3%), respectively. 30‐day hematoma rates were overall low: 135 (0.8%) in TT, 57 (0.5%) in TL, and < 10 (0.7%) in CT (p < 0.01). 30‐day vocal cord dysfunction was documented in 233 (1.4%), 159 (1.3%), and < 10 (1.0%) for TT, TL, and CT, respectively (p = 0.65). Temporary hypoparathyroidism was more common after TT than CT (989 (6%) versus 20 (2%), p < 0.01). Among 16,311 (49%) patients with reported long‐term outcomes, there were no differences in the rates of vocal cord dysfunction by type of operation (p = 0.34). However, long‐term hypoparathyroidism was more likely after TT than CT (237 (2.5%) versus < 10 (0.7%), p < 0.01).ConclusionIn this multi‐institutional endocrine surgery database, the reported long‐term complication rates after completion thyroidectomy were the same as for first‐time thyroid lobectomy. However, clinical hypoparathyroidism was 2.5‐fold more likely for total thyroidectomy than for completion thyroidectomy at 30‐days and remained 3.7‐fold higher in the long term suggesting that completion thyroidectomy does not pose a higher risk of complications.

ImportanceAdrenalectomy is the definitive treatment for multiple adrenal abnormalities. Advances in technology and genomics and an improved understanding of adrenal pathophysiology have altered operative techniques and indications.ObjectiveTo develop evidence-based recommendations to enhance the appropriate, safe, and effective approaches to adrenalectomy.Evidence ReviewA multidisciplinary panel identified and investigated 7 categories of relevant clinical concern to practicing surgeons. Questions were structured in the framework Population, Intervention/Exposure, Comparison, and Outcome, and a guided review of medical literature from PubMed and/or Embase from 1980 to 2021 was performed. Recommendations were developed using Grading of Recommendations, Assessment, Development and Evaluation methodology and were discussed until consensus, and patient advocacy representation was included.FindingsPatients with an adrenal incidentaloma 1 cm or larger should undergo biochemical testing and further imaging characterization. Adrenal protocol computed tomography (CT) should be used to stratify malignancy risk and concern for pheochromocytoma. Routine scheduled follow-up of a nonfunctional adrenal nodule with benign imaging characteristics and unenhanced CT with Hounsfield units less than 10 is not suggested. When unilateral disease is present, laparoscopic adrenalectomy is recommended for patients with primary aldosteronism or autonomous cortisol secretion. Patients with clinical and radiographic findings consistent with adrenocortical carcinoma should be treated at high-volume multidisciplinary centers to optimize outcomes, including, when possible, a complete R0 resection without tumor disruption, which may require en bloc radical resection. Selective or nonselective α blockade can be used to safely prepare patients for surgical resection of paraganglioma/pheochromocytoma. Empirical perioperative glucocorticoid replacement therapy is indicated for patients with overt Cushing syndrome, but for patients with mild autonomous cortisol secretion, postoperative day 1 morning cortisol or cosyntropin stimulation testing can be used to determine the need for glucocorticoid replacement therapy. When patient and tumor variables are appropriate, we recommend minimally invasive adrenalectomy over open adrenalectomy because of improved perioperative morbidity. Minimally invasive adrenalectomy can be achieved either via a retroperitoneal or transperitoneal approach depending on surgeon expertise, as well as tumor and patient characteristics.Conclusions and RelevanceTwenty-six clinically relevant and evidence-based recommendations are provided to assist surgeons with perioperative adrenal care.
