However, its utility in PHPT caused by multiple\u2010gland disease (MGD) is still debated, for both detection and prediction of adequate resection. Our hypothesis is that once MGD is encountered during an operation, more stringent criteria for determining adequate resection can improve cure rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective cohort study of patients with PHPT who were found to have MGD during the course of focused parathyroidectomy.

Of the 207 study patients with MGD, 193 were cured and 14 had persistent hyperparathyroidism. After final gland excision, the mean \u00b1 SEM percentage decrease in IOPTH from the baseline was of significantly greater magnitude for the cured group (90.0 \u00b1 0.5%) than for the persistent group (74.0 \u00b1 3.8%) (<jats:italic>p<\/jats:italic> &lt; 0.01). The mean \u00b1 SEM IOPTH after completed multigland excision was higher in the persistent group (44.0 \u00b1 8.4 pg\/ml) than in the cured group (34.0 \u00b1 3.5 pg\/ml) (<jats:italic>p<\/jats:italic> = 0.19), although both were within the normal range (12\u201365 pg\/ml). When the groups were analyzed for an incremental fall of IOPTH from the baseline, the criteria of \u226575% drop and into the normal range improved the positive predictive value from 93.2 to 96.6%
