Abstract
We conducted a meta-analysis of randomized and 2-arm prospective or retrospective
studies that compared the efficacy of PTX and TPTX+AT in patients with medically uncontrollable
secondary HPT due to chronic renal failure. Citations were identified in the Medline,
Cochrane, EMBASE, and Google Scholar databases through April 2014. The primary outcome
of interest was HPT recurrence rate, while secondary outcomes included changes in
serum calcium (Ca++ ), parathyroid hormone (PTH), alkaline phosphatase (ALP), and phosphate (P) levels.
Five studies were included in the present analysis. The NOS score of all the included
studies was 7 or above, and heterogeneity among the studies was minimal for 3 of the
5 outcomes. The HPT recurrence rate was similar for patients who underwent SPTX vs.
TPTX+AT [odds ratio (OR)=0.825; 95% confidence interval (CI)=0.368 to 1.846; p=0.639].
The changes in serum Ca++ , PTH, ALP, and P were also similar between the 2 treatment groups (Ca++ : Std diff in means=− 0.166; 95% CI=− 0.703 to 0.371; p=0.545; PTH: pooled diff in
means=561.17; 95% CI=–174.30 to 1296.6; p=0.135; ALP: pooled diff in means=0.58; 95%
CI=− 70.07 to 71.24; p=0.987; P: pooled Std diff in means=0.26; 95% CI=− 0.091 to
0.630; p=0.143). Our findings indicate that SPTX and TPTX+AT are equally successful
in preventing recurrent HPT and improving secondary HPT. We therefore, conclude that
the choice of procedure can be left to the surgeons.
