Donatini G, Marciniak C, Lenne X, et al. - Via performing a nationwide retrospective cohort study on the “Programme de Medicalisation des Systemes d’Information,” the French administrative database that obtains information on all healthcare facilities’ discharges, researchers here examined the incidence of redo surgery after targeted parathyroidectomy for primary hyperparathyroidism. In the study period, a focused parathyroidectomy by open (88.7%) or endoscopic approach was performed on 13,247 patients (median age 63, F/M = 3.6). Remedial surgery was required in 2.8% at 2 years. Multivariate analysis suggested the following factors as predictive of redo surgery: cardiac history, obesity, endoscopic approach, and low-volume center. An annual caseload of 31 parathyroidectomies was identified to be the best threshold to differentiate high-volume centers and suggested carrying the lowest morbidity/failure rate.
