Donatini G, Marciniak C, Lenne X, et al. - Researchers conducted a nationwide retrospective cohort study investigating the incidence of redo surgery after targeted parathyroidectomy for primary hyperparathyroidism. Using the “Programme de Medicalisation des Systemes d’Information,” the French administrative database, they identified 13,247 patients (median age 63, F/M = 3.6) who had a focused parathyroidectomy by open (88.7%) or endoscopic approach from 2009 to 2018. Despite the value of focused parathyroidectomy as a standardized operation, there were strong correlations of cure rate with annual hospital caseload, type of procedure (endoscopic), and patients’ features (obesity, cardiac history). Based on findings, they emphasize considering an open surgery in a high-volume center for patients with risk factors for redo surgery.
