Nerve monitoring in endocrine surgery: Practice patterns differ among surgeons for parathyroidectomy and thyroidectomy.

BACKGROUND: It is unknown whether intraoperative nerve monitoring is associated with reduced vocal cord dysfunction after parathyroidectomy. We aimed to investigate intraoperative nerve monitoring use among Collaborative Endocrine Surgery Quality Improvement Program surgeons and factors associated with vocal cord dysfunction after parathyroidectomy. METHODS: Patients who underwent parathyroidectomy included in the Collaborative Endocrine Surgery Quality Improvement Program (2014-2022) were identified. The annual percent change in parathyroidectomies performed with intraoperative nerve monitoring was calculated using joinpoint regression. Multivariable logistic regression was used to compare outcomes between patients undergoing parathyroidectomy with/without intraoperative nerve monitoring. To compare surgeon-specific trends, Collaborative Endocrine Surgery Quality Improvement Program thyroidectomy and parathyroidectomy datasets (2014-2021) were combined. Parathyroidectomies performed by surgeons who used intraoperative nerve monitoring consistently in thyroidectomy were identified. Factors associated with intraoperative nerve monitoring were examined using multivariable logistic regression. RESULTS: A total of 9,813 patients underwent parathyroidectomy. Intraoperative nerve monitoring was used in 49% of cases (n = 4,818). There was an increase in parathyroidectomies with intraoperative nerve monitoring from 2014 to 2018 (annual percent change 22.2, P = .01), followed by a plateau (2018-2022 annual percent change -0.66, P = .85). Few patients (0.44%, n = 43) developed vocal cord dysfunction. Vocal cord dysfunction was not associated with intraoperative nerve monitoring (adjusted odds ratio 0.92, P = .75). Whereas 41% (n = 56/138) of surgeons used intraoperative nerve monitoring routinely in parathyroidectomy, 65% (n = 90/138) used it routinely in thyroidectomy. Among surgeons who used intraoperative nerve monitoring routinely in thyroidectomy, only 57% used it routinely in parathyroidectomy; factors associated with intraoperative nerve monitoring during parathyroidectomy included reoperation (adjusted odds ratio 2.51, P < .01), secondary/tertiary hyperparathyroidism (adjusted odds ratio 1.42, P = .02), multiglandular disease (adjusted odds ratio 1.76, P < .001), and non-localized disease (adjusted odds ratio 1.65, P < .001). CONCLUSION: Endocrine surgeons use intraoperative nerve monitoring selectively. Surgeons who routinely use intraoperative nerve monitoring during thyroidectomy are more likely to use it during parathyroidectomy. Future studies should determine who may benefit most from intraoperative nerve monitoring in parathyroidectomy.

Somatic and Germline Mutations in Atypical Parathyroid Tumors.

This case series examines somatic and germline mutations in atypical parathyroid adenomas using broad next-generation sequencing of tumor samples obtained from patients who underwent surgical resection from 2020 to 2022.

Feasibility and efficacy of cryoneurolysis analgesia in robotic-assisted thoracoscopic surgery (CARTS): a pilot study.

Opioid therapy has been the mainstay therapy of post-operative pain management in thoracic surgery patients. With the high incidence of chronic pain in thoracic surgery patients and adverse effects of opioids, we examined the safety and efficacy of cryoneurolysis as an adjunct for narcotic-free pain management in robotic-assisted thoracoscopic lobectomies. Ten consecutive patients undergoing robotic-assisted (DaVinci) pulmonary resection and cryoneurolysis were compared to ten patients managed without intraoperative cryoneurolysis. All patients received multimodal pain regimen including paravertebral blocks as per our institutional enhanced recovery pathway. Patients with chronic pain and chronic opioid use were excluded. We compared inpatient and outpatient opioid consumption measured in morphine equivalents (mme), incidence of opioid-free outpatient recovery, and adverse events. The two groups did not differ significantly in terms of baseline demographics. Both inpatient (88.13 vs 26.92 mme) and outpatient (118.5 vs 34.5 mme) use of narcotics were significantly lower in the cryoneurolysis group (p < 0.05) with seven of ten patients receiving cryoneurolysis able to recover without the use of opioids in the outpatient setting, compared to two in the control group. One patient reported post-operative neuralgia in each cryoneurolysis and control group. There were no readmissions in either group and mean length of stay was identical at 1.7 days in control group and 1.1 days in experimental group (p = 0.33). The use of intraoperative intercostal cryoneurolysis may safely reduce the utilization of outpatient opioids in patients undergoing robotic-assisted thoracoscopic surgery. A randomized controlled trial is warranted to validate these findings in a larger cohort of patients.
