RESUMEN
BACKGROUND: Current thyroid hormone replacement therapy (THRT) is built on weight-based standard calculation of dose. A novel Poisson regression model, which accounts for seven clinical variables, was recently proposed to improve accuracy of THRT. We aimed to compare the accuracy of estimated THRT dose to reach euthyroid and the difference in predicted dose between the Poisson (scheme A) and the weight-based standard (scheme B) in patients following total thyroidectomy for benign disease. METHODS: We retrospectively reviewed medical record of patients who underwent total or completion thyroidectomy for benign disease at a single institution between 2011 and 2019. The THRT dose was calculated using both schemes. We compared the difference between calculated THRT and prediction rates for optimal THRT dosing needed to achieve a euthyroid state between dosing schemes. Patients were evaluated for achieving euthyroid state, defined as TSH 0.45-4.5 mIU/L. We also compared dosing error rates (> 25 mcg over- and underdosing) between schemes. Prediction rates were compared by BMI tertiles to account for the effect of BMI extremes in achieving euthyroid state. The difference in predicted dose between schemes was calculated in both the total sample size and patients that met euthyroid. A measure of agreement, Kappa, was used to estimate agreement between dosing schemes. RESULTS: A total of 406 patients underwent total thyroidectomy for benign disease, with 184 having sufficient follow up data confirming euthyroid state. Of the 184 patients, 85.9% (n = 158) were women, 81% (n = 149) were Hispanic, and 56.5% (n = 104) were obese with a median BMI of 30.8 kg/m2. Scheme A resulted in a higher, but not statistically significant, accuracy rate (A: 60.3%, n = 111 versus B: 53.8%, n = 99; P = 0.21). Overdosing errors were lower with Scheme A (A:17.9% versus B: 32.1%; P = 0.0025) and less extreme > 25 µg (A: 17.9% versus B: 26.1%; P = 0.08). A trend in improved accuracy in patients with a BMI > 35 kg/m2 was noted (A: 46.9% versus B: 34.4%; P = 0.20). Scheme A also resulted in less overdosing errors in obese patients compared to Scheme B (A: 19.2% versus 45.2%; P = 0.0006). The average difference in predicted dose between schemes was an entire dose difference, mean of 16.0 µg and 15.8 µg for the total and euthyroid samples respectively. Furthermore, for the majority of patients the predicted dose did not match between the two dosing schemes for total and euthyroid samples, 76% (n = 311) and 76% (n = 141) respectively. In patients that achieved euthyroid, agreement between dosing schemes was low to moderate (Kappa = 0.360). CONCLUSIONS: Lower rates of overdosing were found for scheme A, particularly with obese patients. No statistically significant differences in predicted THRT dose was observed between schemes. The difference in predicted dose between schemes was on average 15 ug, correlating with an entire dose. The consideration of clinical variables other than weight (scheme A) when determining optimal THRT dosing may be of importance to prevent overdoses, with particular clinical relevance in patients with higher BMIs.

BACKGROUND: Perioperative opioid use has been linked to abuse potential by patients, leading surgeons to scrutinize their postoperative prescribing practices. The goal of the study was to review analgesic regimens for patients undergoing thyroidectomy and parathyroidectomy and extrapolate changes that could be made to decrease opioid use while maintaining adequate pain control. MATERIALS AND METHODS: A literature review was performed. Inclusion criteria were studies 1) written in English, 2) published within the last 20 years, and 3) that included human subjects. Exclusion criteria were studies that 1) evaluated anesthesia regimens exclusively, 2) compared surgical approaches and their effects on pain (e.g., open neck exposure vs. transoral route for thyroidectomy), or 3) included patients undergoing concurrent lateral neck dissection. Of 951 studies originally identified, 10 studies met the criteria. RESULTS: Ten studies were identified, and each evaluated a different analgesic regimen. Five of the studies found a decrease in pain with multimodal regimens. Of the remaining studies, three found no difference in pain control, one found an increase in pain when only an opioid patient-controlled analgesia was used, and one found that 93% of patients required less than 20 oral morphine equivalents postoperatively. CONCLUSIONS: There is no postoperative analgesic regimen that has been established as optimal for patients undergoing parathyroidectomy and thyroidectomy in the current medical literature. However, half of the studies included in this review found that nonopioid adjuncts decreased patients' need for postoperative opioids.

BACKGROUND: The opioid epidemic prompted reevaluation of surgeons' opioid prescribing practices. This study aimed to demonstrate noninferiority of a staged analgesic regimen after endocrine surgery. METHODS: We conducted a randomized controlled trial comparing analgesic regimens after thyroidectomy and/or parathyroidectomy. Adult patients (≥18 years) were randomized to study arm (A) as-needed acetaminophen + codeine or (B) scheduled acetaminophen/as-needed tramadol. Patients recorded pain scores and analgesics consumed in a study log. Clinical variables were collected from the medical record. RESULTS: Target enrollment was achieved (n = 126), and randomization was even (A: 44.5%, B: 55.6%). There was no difference between enrolled patients and those who returned the study log (52.4%) by sex (P = .667), age (P = .513), final pathology (P = .137), procedure (P = .667), or randomization arm (P = .795). Most patients (50.8%) reported moderate pain scores (4-6) with no difference between study arms (P = .451). There was no difference in average consumption by morphine milligram equivalents (A: 11.5 ± 12.1 vs B: 12.49 ± 18.07; P = .792) nor total analgesic doses (A: 7.29 ± 7.48 vs B: 8.5 ± 5.36; P = .445). However, a significant difference in average percentage of opioid doses was noted (A: 79.71 ± 33.31 vs B: 27.38 ± 31.88; P < .001). CONCLUSION: Patients reported moderate pain scores with low requirements for analgesics after endocrine surgery. The staged analgesic regimen is noninferior to combination opioids and led to reduced overall consumption.

INTRODUCTION: We describe a multimethod, multi-institutional approach documenting future competencies required for entry into surgery training. METHODS: Five residency programs involved in a statewide collaborative each provided 12 to 15 subject matter experts (SMEs) to participate. These SMEs participated in a 1-hour semistructured interview with organizational psychologists to discuss program culture and expectations, and rated the importance of 20 core competencies derived from the literature for candidates entering general surgery training within the next 3 to 5 years (1â¯=â¯importance decreases significantly; 3â¯=â¯importance stays the same; 5â¯=â¯importance increases significantly). RESULTS: Seventy-three SMEs across 5 programs were interviewed (77% faculty; 23% resident). All competencies were rated to be more important in the next 3 to 5 years, with team orientation (3.87 ± 0.81), communication (3.82 ± 0.79), team leadership (3.81 ± 0.82), feedback receptivity (3.79 ± 0.76), and professionalism (3.76 ± 0.89) rated most highly. CONCLUSIONS: These findings suggest that the competencies desired and required among future surgery residents are likely to change in the near future.

Historically, thyroidectomies have been performed as inpatient operations due to concerns of postoperative bleeding and symptomatic hypocalcemia. We aim to demonstrate that outpatient thyroidectomy can be performed safely. METHODS: This report outlines a 7-year retrospective analysis (2009-2016) of outpatient vs inpatient thyroidectomies, with outcomes including hematoma, blood loss, recurrent laryngeal nerve injury, symptomatic hypocalcemia, and postoperative emergency room (ER) visits. RESULTS: A total of 1460 thyroidectomies were performed: 1272 (87%) outpatient and 188 (13%) inpatient. Five outpatients: 4 total thyroidectomies (TT), 1 TT with a central lymph node dissection (CLND), and 1 partial thyroidectomy (PT) developed postoperative hematomas (0.34%) at post-discharge hour 3, 9, 10, 13, and 42. Average time to discharge was 2 hours and 37 minutes. Hematomas were evacuated successfully in the operating room under local anesthesia with a 2-day average hospital stay. There were no differences between TT, thyroid lobectomy (TL), and PT procedures for postoperative hematoma (p=0.17). Outpatient compared to inpatient thyroidectomy was more likely to have been performed in patients with lower American Society of Anesthesia scores (2.3 vs 2.9, p<0.0001), less mean blood loss (74 vs 227 ml, p<0.0001), lesser age (52 vs 56 years, p=0.0012), less extensive dissection (p<0.0001), and fewer RLN injuries (2.4% vs 8.5%, p<0.0001). There was no difference between outpatient and inpatient symptomatic hypocalcemia (6.3% vs 9.6%, p=0.09), 30-day postoperative ER visits (8.8% vs 9.6%, p=0.73), and postoperative hematoma (0.39% vs 0%, p=0.39). There was one inpatient mortality from stroke. CONCLUSION: Postoperative hematomas can be managed safely without life-threatening complications suggesting outpatient thyroidectomy can be performed safely by an experienced surgeon, and adverse sequelae dealt with in a safe and effective manner.

INTRODUCTION: Operative treatment of renal tumors can be associated with a high rate of perioperative morbidity related to hemorrhage and injury to adjacent anatomical structures. This morbidity of solid organ surgery is especially prevalent when the lesion involves chronic inflammation or a desmoplastic reaction from a rapidly growing tumor. No consensus on the use of transarterial embolization has been fashioned as the number of prospective studies is small. This study proposes to examine the beneficial effects of selective transarterial embolization of the kidney prior to surgical resection. PRESENTATION OF CASE: A retrospective case matched review was performed of consecutive nephroureterectomies evaluating outcomes of patients receiving transarterial embolization versus those patients who received no embolization. The records were obtained from University Medical Center of El Paso for the time period of 05/2011-12/2014. Data examined included patient demographics, operative blood loss, operative time, transfusion requirements, and pathology. Previous studies have shown that preoperative embolization of renal tumors resulted in a decreased need for blood transfusion. CONCLUSION: Our review showed transarterial embolization had a decrease in blood loss and required no transfusions. It also facilitated a larger and more advanced tumor resection. Our series of patients tolerated transarterial embolization well and had good surgical outcomes. Transarterial embolization of kidneys prior to radical nephroureterectomy results in a safe and uncomplicated operative course with less perioperative morbidity when compared to resection alone.
RESUMEN
PURPOSE: To identify, using tissue microarray (TMA), an immunohistochemical panel predictive of response to ionizing radiation (IR) in rectal cancer. METHODS: TMA constructs were prepared from archived stage II/III rectal tumors and matching adjacent mucosa (n=38) from patients treated with pre-operative chemoradiation. Immunohistochemistry (IHC) was performed for MIB, Cyclin E, p21, p27, p53, survivin, Bcl-2, and BAX. Immunoreactivity along with clinical variables was subjected to univariate and forward stepwise logistic regression analyses. RESULTS: Pathological complete response (pCR) was 23.9%. The number of positive lymph nodes obtained in the resected specimen was associated with pCR. Immunoreactivity for MIB (Sn 15%, Sp 65%, OR 0.33), p53 (Sn 3%, Sp 84%, OR 0.16), Bcl-2 (Sn 11%, Sp 74%, OR 0.35), and BAX (Sn 92%, Sp 80%, OR 46) was associated with pathological response (all p's<0.001). Forward stepwise logistic regression analysis demonstrated that MIB was an independent predictor of a response to chemoradiation (p=0.001). CONCLUSIONS: A combined panel of mediators of apoptosis alone or combined with clinical factors is a feasible approach that can be applied to rectal tumor biopsies to predict a response to chemoradiation. The most sensitive factor was BAX; while MIB independently predicted a response to chemoradiation.
