Patient, thyroid, and surgeon related factors that make thyroidectomy difficult-cohort study.

ABSTRACT:

Introduction

When thyroidectomy is performed under optimal conditions within a milieu of sound anatomical and physiological knowledge combined with meticulous surgical skills, complications are minimal. However, thyroidectomy can be difficult, and its complications can be life-threatening. The factors that predict difficult thyroidectomy can be patient-, thyroid-, or surgeon-related, and we aimed to study these three factors. .

Materials and methods

This prospective study was performed in a tertiary care center between September 2016 and March 2017. We developed and validated modified thyroidectomy difficulty scale (TDS), with 11 items. Preoperatively, height, weight, neck length, and other parameters were recorded. Postoperatively, the modified TDS form was filled out by the surgeon and assistant, blinded to each other's responses. The minimum score was 19 and maximum was 54. The surgeon's baseline pulse rate was monitored throughout the procedure using a pulse oximeter probe that was On-The-Go (OTG) compatible. The probe was placed over the ear lobule/pinna of the surgeon and connected to an Android phone that was comfortably placed in the surgeon's pocket inside the gown. An application USB SPO₂, was used in recording the pulse rate.

Results

A total of 52 patients undergoing hemi- or total thyroidectomy were included in this study. All had benign cytology on fine needle aspiration cytology (colloid, 71.42%). A total of 104 modified TDS questionnaires filled by the operating surgeon and assistant were analyzed. The pulse rate of the operating surgeon, as measured by the novel pulse oximeter, was recorded in 52 surgeries. The minimum score was 20, maximum score was 35.50, and mean score was 26.85 ± 2.80. There was an interobserver agreement in most domains of the modified TDS except mobility. The surgeon was found to have the maximum heart rate when performing recurrent laryngeal nerve (RLN) dissection in 38 patients (73.07%).

Discussion

We found that majority of the trainees found thyroidectomy to be a vigorously intense activity. Thyroidectomy is a demanding surgery, which requires meticulous identification and dissection of the RLN and parathyroid glands for optimum outcome.

Project description:ObjectivesLevothyroxine suppressive therapy following thyroidectomy for thyroid cancer patients is considered as a risk factor for osteoporosis and fragility fractures. We evaluated the association of regular exercise and exercise habit change with fracture risk in adults older than 40 years who underwent thyroidectomy for thyroid cancer.MethodsWe enrolled the patients who underwent thyroidectomy for thyroid cancer older than 40 years between 2010 and 2016 from the Korean National Health Insurance Service data, and they were followed through 2019. Based on the questionnaire of health examination within 2 years before and after surgery, whether regular exercise once a week was evaluated. The reference group for the statistical analysis was the continuing lack of physical activity group that did not exercise before or after surgery. For fractures newly diagnosed during the follow-up period, univariate and multivariate Cox regression analyses were performed for risk evaluation.ResultsWe evaluated 74,774 subjects, of whom 2,924 (3.9%) experienced any fractures during a median follow-up of 4.5 years. Compared with the group consistently lack of physical activity, the group that exercised before and after surgery showed a significant decrease in the risk of any fracture, vertebral fracture, and hip fracture: adjusted hazard ratio 0.848 (95% Confidence Interval 0.771-0.932), 0.703 (0.591-0.836), and 0.405 (0.224-0.732), respectively. For vertebral fracture, a significant reduction in fracture risk was confirmed even in patients who started their regular exercise after surgery: adjusted hazard ratio 0.779 (0.648-0.936). The risk reduction for vertebral fractures upon the initiation of exercise was found to be significant in the high-risk groups of patients: women and total thyroidectomy patients.ConclusionWe suggest that maintaining or starting regular exercise after surgery may help prevent fractures in thyroid cancer patients older than 40 years who have undergone thyroidectomy.

Project description:Importance:It is important that clinicians understand consequences of thyoridectomy on swallowing from the patient perspective to better care for this population. Objective:Using rigorous qualitative methodology, this study set out to characterize the effect of swallowing-related symptoms after thyroidectomy on patient quality of life and swallowing-related outcomes. Design, Setting, and Participants:Prospective, grounded theory analysis of interviews with 26 patients at 3 time points after thyroidectomy (2 weeks, 6 weeks, and 6 months). Data were collected from an ongoing clinical trial (NCT02138214), and outpatient interviews were conducted at the University of Wisconsin Hospital and Clinics. All participants were age 21 to 73 years with a diagnosis of papillary thyroid cancer without cervical or distant metastases and had undergone total thyroidectomy. Exclusion criteria were preexisting vocal fold abnormalities (eg, polyps, nodules), neurological conditions affecting the voice or swallowing ability, and/or development of new-onset vocal fold paresis or paralysis (lasting longer than 6 months) after total thyroidectomy. Interventions:Total thyroidectomy. Main Outcomes and Measures:Symptoms of dysphagia and related effects on quality of life elicited through grounded theory analysis of semistructured interviews with patients after thyroidectomy designed to foster an open-ended, patient-driven discussion. Results:Of the 26 patients included, 69% were women (n?=?18); mean (SD) age, 46.4 (14.1) years; mean (SD) tumor diameter 2.2 (1.4) cm. Two weeks after thyroidectomy, 80% of participants (n?=?20) reported at least 1 swallowing-related symptom when prompted by the interview cards; during the open interview, 53% of participants (n?=?14) volunteered discussion of swallowing-related symptoms unprompted. However, only 8% of participants in this study (n?=?2) qualified for a follow-up dysphagia evaluation, indicating that the majority of reported symptoms were subjective in nature. Six weeks and 6 months after thyroidectomy, 42% (n?=?11) and 17% (n?=?4) of participants, respectively, reported continued swallowing symptoms using the prompts; 12% (n?=?3) discussed symptoms without prompting cards at both time points. Conclusions and Relevance:Swallowing symptoms after thyroidectomy are underreported in the literature. This study revealed that as many as 80% of patients who have thyroidectomy may experience swallowing-related symptoms after surgery, and many develop compensatory strategies to manage or reduce the burden of these symptoms. Considering the large number of individuals who may experience subjective dysphagia, preoperative counseling should include education and management of such symptoms.

Project description:ImportanceAlthough the association between annual surgeon total thyroidectomy volume and clinical outcomes is well established, published methods typically group surgeons into volume categories. The volume-outcomes association is likely continuous, but little is known about the point at which the annual surgeon procedure volumes begin to be associated with a decrease in complication rates.ObjectiveTo model the volume-outcomes association as a continuous function and identify the point at which increasing surgeon volume begins yielding better outcomes.Design, setting, and participantsA retrospective cohort study was conducted in 2018 to 2019 on 10 546 patients from 2 Kaiser Permanente regions (Northern and Southern California), who underwent total thyroidectomy from January 1, 2008, through December 31, 2015, and were followed up through December 31, 2017. The association between annual surgeon procedure volume and outcomes was modeled with analyses that accounted for an association of unknown form and surgeon-specific effects, after adjusting for sociodemographics, prior-year utilization, and multiple comorbidities. Data were analyzed from October 2018 to April 2019.ExposureTotal thyroidectomy.Main outcomes and measuresPresence or absence of transient and permanent hypoparathyroidism and vocal cord paralysis (VCP) in relation to surgeon volume of total thyroidectomies.ResultsOf 10 546 patients in this study, 8500 (81.0%) were male and 4877 (46.2%) aged 45 to 64 years. Surgeons with annual volumes of 1 to 9 total thyroidectomies operated on 2912 patients (27.7%), those with an annual volume of 10 to 19 operated on 3404 (32.6%), and those with an annual volume of 20 or more operated on the remaining 4232 (40.6%). During 2008-2015, a mean of 53.5 (range, 46-198) thyroidectomies were performed each year by surgeons with an annual volume of 40 or more procedures. A generalized additive model showed that the occurrence rates of VCP and hypoparathyroidism began to decrease at annual surgeon procedure volumes of 18.2 (95% CI, 15.0-21.5) and 18.1 (95% CI, 13.8-21.3) procedures per year, respectively. The model revealed a subsequent increase in complication rates for transient VCP. With the use of a refined model, statistically significant decreases were noted in the occurrence rates of complications as annual surgeon volumes increased. Among all 10 546 patients who underwent total thyroidectomy, 632 (6.0%) experienced transient hypoparathyroidism and 170 (1.6%) experienced permanent hypoparathyroidism, whereas 440 (4.2%) experienced transient VCP and 182 (1.7%) experienced permanent VCP. Absolute decreases in complication rates when all surgeons had modeled minimum annual procedure volumes greater than 40 were low, ranging from 0.6% for permanent VCP and hypoparathyroidism to 1.5% for transient hypoparathyroidism.Conclusions and relevanceIn this study, occurrence rates of transient and permanent hypoparathyroidism and VCP appeared to decrease as the annual surgeon procedure volume increased, but the absolute decrease may be modest if the affected health system already has low complication rates. Shifting patients to higher-volume surgeons to realize these reductions may be of variable attractiveness in systems with low baseline complication rates.
