[Experiences of unilateral exploration of parathyroid adenoma].

In a series of 135 cases of primary hyperparathyroidism encountered in PUMC Hospital. Unilateral exploration was performed in 55 cases including 49 cases single adenoma, 1 double adenomas, 3 cases hyperplasia, 2 carcinoma and one MEN-I case. All the 3 cases of hyperplasia and 1 double adenomas were reoperations. There was only one case failed due to misguided by imaging diagnosis. The overall success rate of unilateral exploration was 98%. The reason of unilateral exploration is that about 80%-85% cases of hyperparathyroidism were caused by single adenoma. For single adenoma, unilateral exploration is enough and reasonable. The authors considered that once the diagnosis was made and preoperative localization has positive findings in experienced surgeon's hand the successful rate was very high, 2% of failure is acceptable. Technique point was discussed for unilateral exploration.
