The Obesity Paradox in Thyroid Surgery: Is Higher BMI Protective Against Hypoparathyroidism?

BACKGROUND: With a demonstrated association between adiposity and parathyroid hormone (PTH) levels, we hypothesized that patients with a higher body mass index (BMI) would have lower rates of postoperative hypoparathyroidism following total thyroidectomy. METHODS: retrospective review of patients undergoing total thyroidectomy from 2015 to 2021. Demographics, BMI, surgical indications, and laboratory data including pre- and postoperative PTH values were examined. RESULTS: Of the 352 patients with complete clinicopathologic data, most were female (n = 272, 77.3%) with an average age of 42.7 (SD+/-19.4). Obese (BMI 30-39.99) was most common BMI group (n = 108, 30.8%), with 11.7% (n = 41) morbidly obese (BMI > 40). Morbidly obese patients had significantly higher postoperative PTH levels than BMI < 18.5 (46.0 vs 19.3 pg/mL, P = .004). Patient race was significantly associated with pre- and postoperative PTH (P = .03, P = .004.) On multivariable analysis, preoperative PTH, race, and BMI were independent predictors of higher postoperative PTH (P < .05 for all). DISCUSSION: Patients with higher BMI and non-white race have relative protection from postoperative hypoparathyroidism.

Structured Resident Training in Robotic Surgery: Recommendations of the Robotic Surgery Education Working Group.

OBJECTIVE: A universal resident robotic surgery training pathway that maximizes proficiency and safety has not been defined by a consensus of surgical educators or by surgical societies. The objective of the Robotic Surgery Education Working Group was to develop a universal curriculum pathway and leverage digital tools to support resident education. DESIGN: The two lead authors (JP and YN) contacted potential members of the Working Group. Members were selected based on their authorship of peer-review publications, their experience as minimally invasive and robotic surgeons, their reputations, and their ability to commit the time involved to work collaboratively and efficiently to reach consensus regarding best practices in robotic surgery education. The Group's approach was to reach 100% consensus to provide a transferable curriculum that could be applied to the vast majority of resident programs. SETTING: Virtual and in-person meetings in the United States. PARTICIPANTS: Eight surgeons (2 females and 6 males) from five academic medical institutions (700-1541 beds) and three community teaching hospitals (231-607 beds) in geographically diverse locations comprised the Working Group. They represented highly specialized general surgeons and educators in their mid-to-late careers. All members were experienced minimally invasive surgeons and had national reputations as robotic surgery educators. RESULTS: The surgeons initially developed and agreed upon questions for each member to consider and respond to individually via email. Responses were collated and consolidated to present on an anonymized basis to the Group during an in-person day-long meeting. The surgeons self-facilitated and honed the agreed upon responses of the Group into a 5-level Robotic Surgery Curriculum Pathway, which each member agreed was relevant and expressed their convictions and experience. CONCLUSIONS: The current needs for a universal robotic surgery training curriculum are validated objective and subjective measures of proficiency, access to simulation, and a digital platform that follows a resident from their first day of residency through training and their entire career. Refinement of current digital solutions and continued innovation guided by surgical educators is essential to build and maintain a scalable, multi-institutional supported curriculum.

Common Components of General Surgery Robotic Educational Programs.

OBJECTIVE: Robotically assisted surgery has become more common in general surgery, but there is limited guidance from the Accreditation Council for Graduate Medical Education (ACGME) regarding this type of training. We sought to determine common elements and differences in the robotic educational curricula developed by general surgery residency programs. DESIGN: Robotic educational curricula were obtained from the 7 individuals who presented at the workshop, "Robotic Education in General Surgery" at the 2023 Association of Program Directors in Surgery annual meeting. RESULTS: All 7 general surgery programs had training beginning intern year, required online robotic modules, had at least 1 dedicated simulation training console not used for clinical purposes, and ran dry and wet (tissue) robotic labs at least annually. All programs had bedside and console surgeon case minimums and had administrative support to run the educational programs. Differences existed regarding how training intern year was executed, the simulations required, clinical practice minimum requirements, how progress was monitored over time, and how case numbers were tracked. Some programs had salary support for a director of robotic education. CONCLUSIONS: There are several common elements to robotic educational curricula in general surgery, however significant variation does exist between programs. Given the frequency of robotic use in general surgery and current lack of standardization, formal guidance from the ACGME specifically regarding robotic education in general surgery residency is warranted.

Physician-Targeted Interventions Reduce Surgical Expense and Improve Value-Driven Health Outcomes.

INTRODUCTION: Increasing health-care costs in the United States have not translated to superior outcomes in comparison to other developed countries. The implementation of physician-targeted interventions to reduce costs may improve value-driven health outcomes. This study aimed to evaluate the effectiveness of physician-targeted interventions to reduce surgical expenses and improve care for patients undergoing total thyroidectomies. METHODS: Two separate face-to-face interventions with individual surgeons focusing on surgical expenses associated with thyroidectomy were implemented in two surgical services (endocrine surgery and otolaryngology) by the surgical chair of each service in Jun 2016. The preintervention period was from Dec 2014 to Jun 2016 (19 mo, 352 operations). The postintervention period was from July 2016 to January 2018 (19 mo, 360 operations). Descriptive statistics were utilized, and differences-in-differences were conducted to compare the pre and postintervention outcomes including cost metrics (total costs, fixed costs, and variable costs per thyroidectomy) and clinical outcomes (30-d readmission rate, days to readmission, and total length of stay). RESULTS: Patient demographics and characteristics were comparable across pre- and post-intervention periods. Post-intervention, both costs and clinical outcomes demonstrated improvement or stability. Compared to otolaryngology, endocrine surgery achieved additional savings per surgery post-intervention: mean total costs by $607.84 (SD: 9.76; P < 0.0001), mean fixed costs by $220.21 (SD: 5.64; P < 0.0001), and mean variable costs by $387.82 (SD: 4.75; P < 0.0001). CONCLUSIONS: Physician-targeted interventions can be an effective tool for reducing cost and improving health outcomes. The effectiveness of interventions may differ based on specialty training. Future implementations should standardize these interventions for a critical evaluation of their impact on hospital costs and patient outcomes.

Surgical Treatment of Hyperthyroidism Can Be Performed Safely Before a Euthyroid State is Achieved.

Background: The 2016 American Thyroid Association guidelines recommend that hyperthyroid patients should be euthyroid before thyroidectomy. This recommendation is based on low-quality evidence. In this retrospective cohort study, we compare peri- and post-operative outcomes of patients with hyperthyroidism who were controlled versus uncontrolled at the time of thyroidectomy. Methods: A retrospective cohort study was performed on 275 hyperthyroidism patients at a single institution from December 2015 to November 2022. Patients were defined as hyperthyroid if they had a diagnosis of hyperthyroidism with at least one suppressed thyrotropin (TSH). Patients were considered uncontrolled if triiodothyronine or thyroxine (T4) was elevated immediately before surgery. Patient demographics, perioperative data, and postoperative outcomes were compared with Chi-square and Wilcoxon Rank Sum tests, as appropriate. Results: Of the 275 patients, 84.3% were women and 51.3% were uncontrolled at time of surgery. Controlled patients had higher median [interquartile range] TSH (0.4 [0.0, 2.4] mIU/L vs. 0.0 [0.0, 0.0] mIU/L, p < 0.001) and lower free T4 (fT4) (0.9 [0.7, 1.1] ng/dL vs. 3.1 [1.9, 4.4] ng/dL, p < 0.001), respectively. Uncontrolled patients were more likely to be diagnosed with Grave's disease (85.1% vs. 67.9%, p < 0.001) and to undergo surgery due to medication intolerance (12.1% vs. 6%) or history of thyroid storm (6.4% vs. 1.5%) (p = 0.008). Uncontrolled patients were also more likely to take a larger number of preoperative medications (2.3 vs. 1.4, p < 0.001). No patient in either group experienced thyroid storm precipitated by surgery. Controlled patients had shorter operative times (7.3% vs. 19.8% <1 hour, p < 0.014) and decreased median estimated blood loss (15.0 [5.0, 30.0] mL vs. 20.0 [10.0, 50.0] mL, p = 0.002). Both groups experienced similar, low rates of postoperative complications, apart from an increase in temporary hypocalcemia in the uncontrolled group (13.4% vs. 4.7%, p = 0.013). Conclusion: Our study is the largest to date examining the postoperative outcomes of patients with uncontrolled hyperthyroidism who undergo thyroidectomy. Our results affirm that thyroidectomy in actively thyrotoxic patients is safe and will not precipitate thyroid storm.

Postoperative Hypocalcemia in Hyperthyroid Patients: The Parathyroids Aren't Always to Blame.

INTRODUCTION: Hypocalcemia is commonly reported after thyroidectomy and has multiple possible etiologies including: parathyroid devascularization, reactive hypoparathyroidism from relative hypercalcemia in thyrotoxicosis, and abrupt reversal of thyrotoxic osteodystrophy. In patients that are actively hyperthyroid and undergoing thyroidectomy, it is not known how many experience hypocalcemia from nonhypoparathyroidism etiologies. Therefore, our aim was to examine the relationship among thyrotoxicosis, hypocalcemia, and hypoparathyroidism. METHODS: A retrospective review was performed of prospectively-collected data from all patients undergoing thyroidectomy for hyperthyroidism by 4 surgeons from 2016 to 2020. All patients carried a diagnosis of Graves' disease or toxic multinodular goiter. Patient demographics, preoperative medications, laboratory reports, and postoperative medications were reviewed. Hypocalcemia within the first month of surgery despite a normal parathyroid hormone (PTH) level was the primary outcome of interest and was compared between patients with and without thyrotoxicosis. Secondary outcomes were duration of postoperative calcium use and the relationship between preoperative calcium supplementation and postoperative calcium supplementation. Descriptive statistics, Wilcoxon rank-sum, and chi-square tests were used for bivariate analysis, as appropriate. RESULTS: A total of 191 patients were identified, with mean age of 40.5 y (range 6-86). Most patients were female (80%) and had Graves' disease (80%). At the time of surgery, 116 (61%) had uncontrolled hyperthyroidism (thyrotoxic group, Free Thyroxine >1.64 ng/dL or Free Triiodothyronine > 4.4 ng/dL), with the remaining 75 (39%) considered euthyroid. Postoperative hypocalcemia (calcium < 8.4 mg/dL) developed in 27 (14%), while hypoparathyroidism (PTH < 12 pg/mL) was observed in 39 (26%). Thyrotoxic patients comprised a majority of those with hypocalcemia (n = 22, 81%, P = 0.01) and hypoparathyroidism immediately following surgery (n = 14, 77%, P = 0.04). However, a majority of initially hypocalcemic, thyrotoxic patients had normal PTH values within the first month after surgery (n = 17, 85%), pointing to a potential nonparathyroid etiology. On bivariate analysis, no significant relationship was found for thyrotoxic patients with initial postoperative hypocalcemia (18%) and hypoparathyroidism <1-month after surgery (29%, P = 0.29) or between 1 and 6 mo after surgery (2%, P = 0.24). Of the 19 patients in the nonhypoparathyroidism group, 17 (89%) were off all calcium supplements by 6 mo postop. CONCLUSIONS: In patients with hyperthyroidism, those in active thyrotoxicosis at time of surgery have a higher rate of postoperative hypocalcemia compared to euthyroid patients. When hypocalcemia lasts >1 mo postoperatively, data from this study suggest that hypoparathyroidism may not be the primary etiology in many of these patients, who typically require calcium supplementation no more than 6 mo postoperatively.

Modification of a Transvalvular Microaxial Flow Pump for Instantaneous Determination of Native Cardiac Output and Volume.

BACKGROUND: The current Impella cardiopulmonary (CP) pump, used for mechanical circulatory support in patients with cardiogenic shock (CS), cannot assess native cardiac output (CO) and left ventricular (LV) volumes. These data are valuable in facilitating device management and weaning. Admittance technology allows for accurate assessment of cardiac chamber volumes. OBJECTIVES: This study tested the ability to engineer admittance electrodes onto an existing Impella CP pump to assess total and native CO as well as LV chamber volumes in an instantaneous manner. METHODS: Impella CP pumps were fitted with 4 admittance electrodes and were placed in the LVs of adult swine (n = 9) that were subjected to 3 different hemodynamic conditions, including Impella CP speed adjustments, administration of escalating doses of dobutamine and microsphere injections into the left main artery to result in cardiac injury. CO, according to admittance electrodes, was calculated from LV volumes and heart rate. In addition, CO was calculated in each instance via thermodilution, continuous CO measurement, the Fick principle, and aortic velocity-time integral by means of echocardiography. RESULTS: Modified Impella CP pumps were placed in swine LVs successfully. CO, as determined by admittance electrodes, was similar by trend to other methods of CO assessment. It was corrected for pump speed to calculate native CO, and calculated LV chamber volumes trended as expected in each experimental protocol. CONCLUSIONS: We report, for the first time, that an Impella CP pump can be fitted with admittance electrodes and used to determine total and native CO in various hemodynamic situations. CONDENSED ABSTRACT: Transvalvular mechanical circulatory support devices such as the Impella CP do not have the ability to provide real-time information on native cardiac output (CO) and left ventricular (LV) volumes. This information is critical in device management and in weaning in patients with cardiogenic shock. We demonstrate, for the first time, that Impella CP pumps coupled with admittance electrodes are able to determine native CO and LV chamber volumes in multiple hemodynamic situations such as Impella pump speed adjustments, escalating dobutamine administration and cardiac injury from microsphere injection.

Association Between Surgical Indication and Outcomes for Outpatient Adrenalectomy.

INTRODUCTION: Despite a favorable risk-benefit profile, inpatient admission postoperatively for minimally invasive adrenalectomy (MIA) has remained common. Prior studies have shown that outpatient MIA was not associated with an increased 30-day complications or readmission. However, this has not been explored in-depth by adrenalectomy indication. We aimed to examine whether the safety profile of outpatient MIA varies by adrenal indication. MATERIALS AND METHODS: Clinicopathologic parameters were examined for all MIAs entered into an adrenal database at our institution from 2012 to 2021. Predictor variables included patient demographics, surgical indication, and operative time. Outcomes were 30-day emergency department visit, readmission, and complication rates between surgical indications, comparing outpatient and inpatient groups. Statistical analyses were performed using Kruskal-Wallis, Wilcoxon, Mann-Whitney, and Chi-squared tests, as appropriate. RESULTS: A total of 185 MIA patients were included. Outpatient MIA was performed in 53 patients (28.6%). Outpatient discharge post-MIA was related to both surgical indication and operative time. Pheochromocytoma (PC) patients were less likely to be discharged as an outpatient postoperatively when compared to all other indications (13.0% versus 33.8%, P = 0.007). Among all patients with operations 2-3 h in length, PC patients were less likely to be discharged home as an outpatient (10% versus 33.3%, P = 0.040). No significant differences were identified between outpatient and inpatient MIA groups for complications, emergency department visits, or readmission (P > 0.05 for all). Only six outpatient MIA patients had any complication (11.3%) and six were readmitted (11.3%). CONCLUSIONS: Outpatient MIA was demonstrated to be associated with similar, low complication and readmission rates compared to inpatient MIA, although it was used less often for patients with PC or prolonged operative times. Our study highlights potential evidence that outpatient MIA can be safely used in selected patients across all indications for adrenal surgery.

Comparison of Perioperative Outcomes Between Single-Port and Multi-Port Robotic Adrenalectomy.

BACKGROUND: Single-port (SP) robotic surgery has been utilized in several surgical procedures. We aim to describe our institution's approach and perioperative experience with SP robotic adrenalectomy and compare it to the traditional multi-port (MP) approach. METHODS: We retrospectively reviewed all patients who underwent robotic adrenalectomy by a single surgeon between March 2019 and March 2020. Patient demographic, perioperative factors, and pathologic outcomes were recorded and analyzed using t-tests, chi-square, or Fisher's exact tests. RESULTS: Thirty-six patients underwent SP (n = 11) and MP (n = 25) robotic adrenalectomy. Age, body mass index, gender, operative time, major Clavien-Dindo complications, and margin status showed no differences. Patients undergoing SP adrenalectomy had a lower estimated blood loss (18.1 ± 13.0 vs 65.6 ± 95.0 cc, P = .02) and smaller lesion size (2.8 ± 1.3 vs 4.1 ± 1.8 cm, P = .04) compared to those undergoing MP. CONCLUSIONS: SP adrenalectomy appears to be a feasible approach in select adrenal masses. Further studies are needed to establish its safety and cost effectiveness.

The University of Alabama at Birmingham Surgery Community Network: Tackling the Challenges of Rural Surgery.

Over the past 5 years, The University of Alabama at Birmingham (UAB) Department of Surgery has taken a keen interest in the practice of surgery in rural Alabama and has established the UAB surgery community network. Our goal is to improve the delivery of surgical care in rural areas through active recruitment of rural surgeons, the development of research around rural surgery practice, and the expansion of a surgery network throughout the state. Here, we will present the challenges faced by rural surgery, our early work to address these challenges, and offer a plan for moving forward.

Concurrent Validity Evidence for Entrustable Professional Activities in General Surgery Residents.

BACKGROUND: A subset of Entrustable Professional Activities (EPAs) has been developed for general surgery. We aim to contribute validity evidence for EPAs as an assessment framework for general surgery residents, including concurrent validity compared to ACGME milestones, the current gold standard for evaluating competency. STUDY DESIGN: This is a cross-sectional study in a general surgery training program within a tertiary academic medical center. EPA assessments were submitted using a mobile app and scored on a numerical scale, mirroring milestones. EPA score distribution was analyzed with respect to post-graduate year (PGY) level and phase of care. Proportional odds logistic regression identified significant predictors. Spearman rank and Wilcoxon rank tests were used for comparisons with milestone ratings. RESULTS: From August 2018 to December 2019, 320 assessments were collected. EPA scores increased by PGY level. Operative phase EPA scores were significantly lower than nonoperative phase scores. PGY level, operative phase, and case difficulty significantly influenced entrustment scoring. EPA scores demonstrated strong correlation with nonoperative milestones patient care-1, medical knowledge-1, interpersonal and communication skills-2, interpersonal and communication skills-3, professionalism-1, professionalism-3, and practice-based learning and improvement-2 (ρ > 0.5, p < 0.05) and a weaker correlation with operative milestones patient care-3 and medical knowledge-2 (ρ < 0.5, p < 0.05). CONCLUSIONS: The influence of PGY level and operative phase on entrustment scoring supports the validity of EPAs as a formative evaluation framework for general surgery resident performance. In addition, evident correlations between EPA scores and respective milestone ratings provide concurrent validity evidence.

Smart Drain for Post-Cardiac Surgery Left Ventricular Volumes Evaluated in Large Animal Models.

BACKGROUND: Open heart surgeries for coronary arterial bypass graft and valve replacements are performed on 400,000 Americans each year. Unexplained hypotension during recovery causes morbidity and mortality through cerebral, kidney, and coronary hypoperfusion. An early detection method that distinguishes between hypovolemia and decreased myocardial function before onset of hypotension is desirable. We hypothesized that admittance measured from a modified pericardial drain can detect changes in left ventricular end-systolic, end-diastolic, and stroke volumes. METHODS: Admittance was measured from 2 modified pericardial drains placed in 7 adult female dogs using an open chest preparation, each with 8 electrodes. The resistive and capacitive components of the measured admittance signal were used to distinguish blood and muscle components. Admittance measurements were taken from 12 electrode configurations in each experiment. Left ventricular preload was reduced by inferior vena cava occlusion. Physiologic response to vena cava occlusion was measured by aortic pressure, aortic flow, left ventricle diameter, left ventricular wall thickness, and electrocardiogram. RESULTS: Admittance successfully detected a drop in left ventricular end-diastolic volume (P < .001), end-systolic volume (P < .001), and stroke volume (P < .001). Measured left ventricular muscle resistance correlated with crystal-derived left ventricular wall thickness (R2 = 0.96), validating the method's ability to distinguish blood from muscle components. CONCLUSIONS: Admittance measured from chest tubes can detect changes in left ventricular end-systolic, end-diastolic, and stroke volumes and may therefore have diagnostic value for unexplained hypotension.

Mediastinal parathyroidectomy: Utilization of a multidisciplinary, robotic-assisted transthoracic approach in challenging cases.

BACKGROUND: The majority of ectopic mediastinal parathyroid adenomas are accessible transcervically and those not amenable to this approach pose a significant clinical and technical challenge. METHODS: Retrospective review of transthoracic robot-assisted mediastinal parathyroidectomy (TTRMP) for primary hyperparathyroidism between 2012 and 2019 at a single institution. RESULTS: 16 patients underwent TTRMP, 63% were female with a mean age of 64 ± 2.0 years. Nine of 16 had prior parathyroidectomy; 80% had persistent disease and a mean 2.8-year delay from index operation until TTRMP. Locations included: intrathymic (8), AP window (4), carina (3), and retroesophageal (1). Two patients underwent parathyroid reimplantation. Mean post-operative calcium and PTH were 9.2 ± 0.2 mg/dL and 20.2 ± 5.6 pg/mL, respectively. Complications included: temporary hypocalcemia (4), permanent hypocalcemia (1), DVT (1), hoarseness (1), and subcostal neuralgia (1). CONCLUSION: In experienced hands, TTRMP is a safe and effective approach to mediastinal parathyroids not accessible transcervically. A multidisciplinary approach should be used in reoperative cases.

Prevalence, Bias, and Rank List Impact of Illegal Questions in Surgical Specialty Residency Interviews.

OBJECTIVE: The purpose of this study is to characterize illegal questions as defined by federal law and to assess their impact on applicants' rank lists across four surgical specialties. DESIGN: A survey was developed and sent to surgical specialty residency applicants. The survey asked demographics, the frequency of questions about age, gender, religion, sexual orientation, family status and impact on final rank list. Applicants were asked to respond anonymously based on their experience at all institutions at which they interviewed during the interview cycle. Results were compared by applicant specialty and gender. SETTING: A large university-affiliated academic medical center PARTICIPANTS: Survey was administered to 3854 applicants (comprising between 28.9% and 41.2% of applicants nationwide) to general surgery, orthopaedic surgery, urology, and otolaryngology residency programs at a single institution during the 2018 and 2019 cycles. A total of 1066 applicants completed the survey. RESULTS: A total of 789 (74.0%) of applicants reported being asked at least one illegal question during the interview process at any institution. Applicants to orthopaedic surgery programs were most likely to be asked illegal question (n = 315, 81.6%), and general surgery applicants were least likely to be asked illegal questions (n = 324, 66.8%, p < 0.001). Females were more likely than males to be asked about gender (n = 99, 26.3% vs. n = 18, 2.6%, p < 0.001) and plans for pregnancy (n = 78, 20.8% vs. n = 78, 11.4%, p < 0.001). 152 (19.4%). Applicants reported that being asked an illegal question lowered a program on their rank list. Female applicants were more likely to lower a program on their rank list as a result of an illegal question (n = 102, 35.4% vs. n = 50, 10.1%, p < 0.001). CONCLUSIONS: Illegal questions in surgical specialty residency interviews are common, vary by specialty and applicant gender, and lower programs on applicants' rank lists. This data should serve to inform larger and more inclusive studies in the future. Programs should focus on educating interviewers on illegal topics in an effort to minimize illegal topics that may alienate applicants and contribute to workplace discrimination.

Patient Satisfaction is Equivalent for Inpatient and Outpatient Minimally-Invasive Adrenalectomy.

INTRODUCTION: Same-day surgery in the carefully selected patient decreases costs, improves inpatient capacity, and decreases patient exposure to hospital-acquired conditions. Outpatient adrenalectomy has been shown to be safe and effective, but patients' perspectives have yet to be addressed. This study compares patient satisfaction following inpatient and outpatient adrenalectomy. METHODS: An institutional database was queried for minimally-invasive adrenalectomies performed from 2017 to 2020. Patients were contacted up to two times to participate in a phone survey consisting of 25 questions modeled after the Outpatient and Ambulatory Surgery Consumer Assessment of Healthcare Providers and Systems Survey (OAS CAHPS) assessing preparation for surgery, discharge experience, post-operative course, and overall satisfaction. Statistical analysis was performed using Kruskal Wallis, Wilcoxon-Mann Whitney, and Chi-square tests, as appropriate. RESULTS: One hundred five adrenalectomy patients were identified, of which 98 were contacted and 58 responded (59%). Two surgeons contributed patients, with no difference in the percentage of patients in the outpatient group (51.7% versus 62.1%, P = 0.423). Outpatient adrenalectomy patients had slightly higher overall experience scores, but this difference was not statistically significant (9.12 ± 1.36 versus 8.93 ± 1.51, P = 0.367). Patients undergoing outpatient adrenalectomy were more likely to have their discharge plan discussed pre-operatively (94% versus 62%, P = 0.005), but no significant differences were noted between inpatient and outpatient groups regarding preparation for surgery, readiness for discharge, night of surgery experiences, or self-reported pain or complications (P > 0.05 for all). Significantly higher overall experience scores were reported by patients counseled about their discharge plan (9.27 versus 7.9, P = 0.036), felt prepared for recovery (9.39 versus 5.5, P < 0.001), received information about pain control (9.13 versus 7.00, P = 0.031), felt prepared at time of discharge (9.33 versus 5.80, P < 0.001), and received information about potential complications (9.29 versus 7.00, P = 0.001). Although not statistically significant, there was a trend towards outpatients being more likely to choose the same approach if they were to undergo surgery again (97% versus 84%, P = 0.081). CONCLUSIONS: Patient satisfaction following adrenalectomy is significantly associated with patients' self-reported degree of preparation for surgery and discharge, with no significant difference in patient satisfaction between inpatient and outpatient groups. Patients undergoing outpatient adrenalectomy would be likely to choose the same approach compared to inpatients. Targeted pre-operative counseling can contribute to enhanced patient outcomes for all patients undergoing adrenalectomy.

Safety of outpatient adrenalectomy across 3 minimally invasive approaches at 2 academic medical centers.

BACKGROUND: Outpatient adrenalectomy has the potential to decrease costs, improve inpatient capacity, and decrease patient exposure to hospital-acquired conditions. Still, the practice has yet to be widely adopted and current studies demonstrating the safety of outpatient adrenalectomy are limited by sample size, extensive exclusion criteria, and no comparison to inpatient cases. We aimed to study the characteristics and safety of outpatient adrenalectomy using the largest such sample to date across 2 academic medical centers and 3 minimally invasive approaches. METHODS: All minimally invasive adrenalectomies were identified, starting from the time outpatient adrenalectomy was initiated at each institution. Cases involving removal of other organs, bilateral adrenalectomies, and cases in which a patient was admitted to the hospital before the day of surgery were excluded. Patient, tumor, and case characteristics were compared between outpatient and inpatient cases, and multivariable regression analysis was used to assess odds of 30-day readmission and/or complication. RESULTS: Of 203 patients undergoing minimally invasive adrenalectomy, 49% (n = 99) were performed on an outpatient basis. Outpatient disposition was more likely in the setting of lower estimated blood loss, case completion before 3 pm, and for surgery performed in the setting of nodule/mass and primary hyperaldosteronism versus Cushing's syndrome, pheochromocytoma, and metastasis (P < .05). There were no significant differences in patient age, body mass index, American Society of Anesthesiologists class, procedure performed, or total time under anesthesia between inpatient and outpatient cases. On adjusted analysis, outpatient adrenalectomy was not associated with increased 30-day readmission rate (odds ratio 0.23 [confidence interval 0.04-1.26] P = .09) or 30-day complication rate (odds ratio 0.21 [confidence interval 0.06-0.81] P = .02). CONCLUSION: Outpatient adrenalectomy can be performed safely without increased risk of 30-day complications or readmission in appropriately selected candidates.

THE NOVEL USE OF STEREOTACTIC RADIOTHERAPY FOR REMNANT ADRENAL TISSUE IN NELSON SYNDROME.

OBJECTIVE: Recurrent Cushing disease (CD) is a rare complication that occurs in patients who have undergone bilateral adrenalectomy (BLA). We report a case of recurrent CD in a patient with Nelson syndrome and adrenalectomy due to remnant adrenal tissue, and a novel treatment strategy using stereotactic body radiation therapy (SBRT) to the adrenal glands. METHODS: We report a case of recurrent CD in a woman with Nelson syndrome and adrenalectomy and describe her clinical course and management. We also include a literature review of CD management and adrenal radiation. RESULTS: The patient had persistent pituitary CD despite pituitary surgery and radiosurgery and underwent BLA. She developed recurrent CD due to a remnant adrenal gland post adrenalectomy. She then underwent SBRT to both adrenal beds to treat the remnant adrenal tissue. Her serum cortisol dropped rapidly after adrenal radiation and she experienced minimal side effects. She has been in remission for over 2 years. CONCLUSION: This is the first reported case of recurrent CD in a patient post adrenalectomy that was successfully treated with SBRT to the remnant adrenal tissue.

Sleep and stress before and after duty across residency years under 2017 ACGME hours.

INTRODUCTION: Residents may differentially experience high stress and poor sleep across multiple post-graduate years (PGYs), negatively affecting safety. This study characterized sleep and stress among medical and surgical residents across multiple PGYs and at specific times surrounding duty. METHOD: Thirty-two medical and surgical residents (Mage = 28.6 years; 56% male) across PGYs 1-5 participated in 3 appointments (immediately before duty, after duty, and on an off day) providing 96 data points. Sleep, stress, and occupational fatigue were measured by both self-report and objectively (actigraphy, salivary coritsol). RESULTS: Residents averaged 7 h of actigraphy-estimated sleep per night but varied ±3 h day-to-day. Residents reported clinically poor sleep quality. Life stress decreased by PGY-2. All residents averaged elevated life stress values. Poor sleep quality did not differ among PGY cohorts. DISCUSSION: Poor sleep quality is similar between early residency cohorts (PGY-1) and later residency cohorts (PGY-3+). Persistent fatigue is highest in later residency cohorts. Even the most experienced residents may struggle with persisting fatigue. Current hour policies may have shortcomings in addressing this risk.
