Outcomes of concurrent parathyroidectomy and thyroidectomy among CESQIP surgeons.

BACKGROUND:Studies comparing endocrine-specific outcomes following parathyroidectomy (PTx) versus concurrent parathyroidectomy and thyroidectomy (PTx + Tx) are few. METHODS:10,019 patients were selected from the Collaborative Endocrine Surgery Quality Improvement Program (2014-2019). Baseline characteristics and short-term (≤30 days) outcomes for PTx + Tx vs PTx patients were compared using bivariate and multivariable methods. RESULTS:PTx + Tx patients were more likely to experience clinical hypoparathyroidism (6.7% vs 0.5%, p < 0.001), recurrent laryngeal nerve transection, (0.4% vs 0.1%, p = 0.002) and hematoma requiring evacuation (1.0% vs 0.2%, p < 0.001). Readmissions and ED visits for hypocalcemia were more frequent after PTx + Tx vs PTx. Concurrent surgery was associated with an 8-fold increase in risk of short-term complications (Odds Ratio (OR): 8.0, 95% Confidence Interval (CI): 5.7-11.1, p < 0.001). CONCLUSIONS:Patients undergoing PTx + Tx have increased rates of postoperative complications, ED visits, and readmissions compared to patients undergoing parathyroidectomy alone. These findings could help guide surgeon-patient discussions on the risks of concurrent surgery.
