原发性甲状旁腺功能亢进症的外科治疗

目的　总结原发性甲状旁腺功能亢进症的外科治疗经验。方法　回顾性分析 1985～2 0 0 2年在我科行外科手术治疗的 5 5例原发性甲状旁腺功能亢进症患者的临床资料。全组病例均行甲状旁腺切除术。结果　 5 5例患者中无症状者 8例 ,骨、关节病变 2 4例 ,泌尿系结石病变 10例 ,骨和泌尿系结石病变 13例 ,病理性骨折 16例。全组血钙均升高 ,在 2 7～ 3 9mmol/L之间 ,平均 (3 1± 0 4 )mmol/L。 5 0例患者术前测定甲状旁腺激素升高在 10 2～ 2 0 0 0pg/ml之间 ,平均 (489 2±6 9 2 ) pg/ml。联合B超、CT、核素扫描术前定位诊断率达 90 9%。术后全组均随访 6个月～ 2年 ,术后临床表现缓解 ,骨质疏松改善 ,骨折愈合 ,有 39例患者出现短期低血钙 ,37例出现面部、手足麻木 ,10例出现手足抽搐。术后有 15例患者血钙正常 ,1例略高于正常值 ,低血钙者经骨化三醇和钙剂治疗 1～ 3周均可改善 ,血钙恢复正常。术后 4 7例患者甲状旁腺激素均在 2个月内恢复到正常 ,3例略高于正常值。结论　甲状旁腺切除术是治疗原发性甲状旁腺功能亢进症的有效方法。经术前影像学定位后行小范围、小创伤的甲状旁腺切除术是可行的手术方法。及时将原发性甲状旁腺功能亢进症患者转入内分泌外科治疗可达到早期治疗、减少骨关节和泌

Surgical treatment for patients with primary hyperparathyroidism

OBJECTIVE: To evaluate the feasibility and efficacy of surgical treatment for patients with primary hyperparathyroidism (pHPT). METHODS: The studies were analyzed for 55 patients with pHPT who underwent parathyroidectomy in our hospital from 1985 to 2002. RESULTS: Eight patients were asymptomatic. The skeletal manifestations were found in 24 cases, urinary stones in 10 cases, and both skeletal manifestations and urinary stones in 13 cases. Pathological bone fractures occurred in 16 cases. Hypercalcemia was discovered in all patients with the average value of (3.1 +/- 0.4) mmol/L, ranging from 2.7 to 3.9 mmol/L and. Fifty patients showed elevated parathyroid hormone (PTH) with the average value of (489.2 +/- 69.2) pg/ml, ranging from 102 to 2,000 pg/ml. Preoperatively all patients underwent sonography, CT and/or scintigraphy. The overall preoperative image-directed localization rate was 90.9%. Follow-up was done from 6 months to 2 years after surgery. The symptoms and signs of all patients relieved postoperatively with the improving of osteoporosis and healing of bone fracture. Of all cases, 39 presented with temporary hypocalcemia, 37 showed circumoral paresthesia in whom 10 showed tetany, 15 showed eucalcemia and one had mild hypercalcemia after operation. The serum calcium was normal in all cases with hypocalcemia by Rocaltrol and calcium supplementation for 1 - 3 weeks. PTH level decreased to normal fro 2 weeks to 2 months in 47 cases and was still mildly higher than normal in 3 cases. CONCLUSIONS: Parathyroidectomy is an effective approach to patients with pHPT. With preoperative image-directed localization techniques, minimally invasive parathyroidectomy is a valid surgical strategy.
