Objective To evaluate the diagnostic significance and to analyze reasons of false negative cases forpreoperative ultrasonography， 99Tcm-sestamibi scintigraphy （MIBI scintigraphy）， and CT in primary hyperparathyroidism（PHPT）. Methods Clinical data of 69 patients with PHPT， who underwent operation in Affiliated Shengjing Hospital of China Medical University between Jan. 2003 and Aug. 2012 were retrospectively analyzed. Results There were 76 parathyroid lesions in 69 PHPT patients proved by operation and pathology， including 58 cases of parathyroid adenoma with 60 lesions， 7 cases of parathyroid hyperplasia with 11 lesions， and 4 cases of parathyroid carcinoma with 5 lesions. The sensitivity of ultrasonography， CT， and 99Tcm-MIBI scintigraphy were 81.94% （59/72）， 61.76% （21/34）， and 69.57% （16/23）， the accuracy of 3 kinds of tests were 78.67% （59/75）， 61.76% （21/34）， and 66.67% （16/24）， the positive predictive value were 95.16% （59/62）， 100% （21/21）， and 94.12% （16/17） respectively. There was significant differ-ence only between ultrasonography and CT in sensitivity （P=0.03）， no other significant difference was found （P＞0.05）.Conclusions Ultrasonography is complementary to 99Tcm-MIBI scintigraphy， but CT has little significance in diagnosis of PHPT. Both of ultrasonography and 99Tcm-MIBI scintigraphy should be used before operation routinely to localize parathyroid lesions.
Objective To analysis causes of reoperation for primary hyperparathyroidism and its clinical characteristics. Method The clinical data of the patients with primary hyperparathyroidism who had undergone reoperation from January 1993 to May 2017 were retrospectively analyzed. Results A total of 11 patients underwent reoperation were collected in the 226 patients with primary hyperparathyroidism. Of the 11 cases, 8 cases underwent twice operations, 2 cases underwent thrice operations, 1 case underwent quintic operation. After the initial operation, 3 cases were persistent diseases and 7 cases were recurrent diseases, 1 patient was not defined as the persistent or recurrent disease. The main clinical manifestations before the reoperation were fatigue, pain in joints, bones, or muscle. The reasons for reoperation included 3 cases of ectopic parathyroid lesions, 3 cases of recurrent parathyroid carcinomas, 1 case of enlarged operation extent for parathyroid carcinoma, 2 cases of regrowth of double parathyroid aedomas, 1 case of missing adenoma, 1 case of parathyroid hyperplasia. Among the location examinations, the 99Tcm-MIBI was most sensitivity (8/9). Eight cases were received reoperation on the original incision, and the remaining 3 ectopic parathyroid lesions on the new incision. After the reoperation, 2 patients were lost of follow-up, 1 patient died, and the remaining 8 patients had no recurrences during follow-up period. Conclusion A comprehensive approach with multiple imageology examinations which attribute to accurate location of lesions, experienced surgeons and well knowledge of parathyroid anatomy and embryology help to descend reoperation ratio and improve success rate of reoperation.
ObjectiveTo compare the clinical effects of unilateral neck exploration (UNE) and direct minimally invasive parathyroidectomy (DPT) in the treatment of primary hyperparathyroidism (PHPT). MethodsThe clinical datas of 87 PHPT patients treated with intraoperative parathyroid hormone monitoring (IPM) -assisted UNE and DMIP in Guizhou Provincial People’s Hospital between January 2016 and December 2021 were analyzed retrospectively. ResultsThe average age of patients was (47.5±13.1) years, and there were 24 males (27.6%) and 63 females (72.4%). The pathological types of 87 cases were parathyroid adenoma in 78 cases (89.7%), atypical parathyroid adenoma in 5 cases (5.7%), parathyroid hyperplasia in 4 cases (4.6%), and no parathyroid carcinoma. Two cases (2.3%) developed recurrent laryngeal nerve injury, and 3 cases (3.4%) developed postoperative persistent hyperparathyroidism, of which 1 (1.1%) case underwent secondary surgery. There were no significant differences in the incidence of recurrent laryngeal nerve injury (2.0% vs. 2.6%, P=0.855) and postoperative persistent hyperparathyroidism between the UNE group and the DMIP group (2.0% vs. 5.3%, P=0.713). However, the intraoperative bleeding volume, operative time, hospitalization time, incision length, and pain score in the DMIP group were significantly less than or shorter than or lower than those in the UNE group (P<0.001). ConclusionThere is no significant difference in the efficacy between the DMIP and UNE in the treatment of PHPT, but DMIP can significantly shorten the operative time and hospitalization time, and reduce the trauma.
目的 探讨原发性甲状旁腺功能亢进症(PHPT)的诊治经验。 方法 回顾性分析我院近15年间18例手术治疗的PHPT患者的临床资料。结果 初诊病例术前核素99Tcm-sestamibi扫描和B超检查阳性定位诊断率分别为100%（9/9）和88%（15/17）。18例均经手术治疗，其中1例为再手术病例。术后病理诊断甲状旁腺腺瘤13例，其中1例为双腺瘤； 甲状旁腺增生4例； 甲状旁腺腺癌1例。首次手术治愈率为88%（15/17）。2例甲状旁腺增生病例未治愈。再手术1例因损伤了单侧喉返神经致术后声音嘶哑。结论 术前核素99Tcm-sestamibi扫描和B超检查对制定手术方案有重要意义，大多数PHPT病例适合行单侧颈部探查术。甲状旁腺增生病例的手术治愈率低。
Vague preoperative localization and ectopic parathyroid often lead to the failure of operation in primary hyperparathyroidism. From Jun 1989 to March 1998, 11 cases of primary hyperparathyroidism had been treated surgically in the general surgery department of our hospital. Of them, 10 cases were operated successfully with the pathological diagnosis of adenoma and one parathyroid removed was reported normal. Preoperative localization, the knowledge of ectopic parathyroids, careful exploration during operation and the postoperative medical treatment are important for the perioperative management. Postoperative followup has emphasized to benefit the treatment in primary hyperparathyroidism.
Objective To summary the experience in diagnosis and managements for primary hyperparathyroidism（PHPT）. Methods The clinical data of 73 patients with PHPT who underwent parathyroidectomy in our hospital from Jan. 2003 to Dec. 2010 were analyzed retrospectively. Results There were 1 case of hyperplasia （1.4%）， 67 cases of adenoma （91.8%）， and 5 cases of adenocarcinoma （6.8%） among the 73 cases of PHPT. The common presentations involved with pain in bones and joints in 63 cases （86.3%）， pathologic fractures in 17 cases （23.3%）， osteoporosis in 59 cases （80.8%）， fatigue in 28 cases （38.4%）， abdominal pain in 4 cases （5.5%）， urolithiasis in 17 cases （23.3%）， malignant hypertension in 1 case （1.4%） who suffered multi-endocrine neoplasm （MEN）Ⅱa， and so on. The preoperativeserum parathyroid hormone （PTH） abnormally elevated in all 73 patients， and serum calcium abnormally elevated in 59 patients （80.8%）， and alkaline phosphatase abnormally elevated in 62 patients （84.9%） before operation. The positive rate of lesion locations by ultrasonography， CT， 99Tcm-sestamibi （MIBI） scan， and the combination of 3 kinds of tests were 82.8% （53/64）， 83.3% （20/24）， 90.2% （46/51）， and 91.8% （67/73） respectively， but 6 cases were not traced preop-eratively. Parathyroidectomy was conducted to all the cases， besides， regional neck lymphadenectomy was performed for those 5 adenocarcinoma cases. Tetany in 16 cases， hoarseness in 2 cases， acute pancreatitis in 1 case， acute left heart failure in 1 case were observed after operation. Sixty nine cases were follow-up for 3-72 months （average 17.3 months）. During the followed-up period， most of them were alleviated from bone pain （43 cases） and fatigue （18 cases）within 1 month. However， the recovery of PTH and serum calcium back to normality were relatively slow. One case ofadenoma recurred， 1 case of adenocarcinoma suffered lung metastasis， 1 case of adenocarcinoma survived for 37 monthsprior to death for postoperative lung and bone metastasis， the other cases （including 1 case of adenocarcinoma developed from adenoma） were still alive and had no metastasis or recurrence by the end of follow-up. Conclusions The symptoms of PHPT vary and lack of specificity， hence， the enhancement of knowledge to this disease and screenings conducted for parathyroid function and serum calcium will increase the rate of diagnosis. Parathyroidectomy is the effective management for PHPT， and preoperatively accurate position contribute to minimal exploration.
目的 探讨甲状旁腺腺瘤所致无症状原发性甲状旁腺功能亢进症（PHPT）的诊断和治疗。方法 回顾性分析中国医科大学附属第一医院1990年1月至2013年4月期间收治的24例甲状旁腺腺瘤所致无症状PHPT患者的临床资料。结果 24例甲状旁腺腺瘤所致无症状PHPT患者中男9例，女15例；年龄（47.92±12.96）岁。均无骨关节疼痛、病理性骨折、泌尿系结石或胃肠道症状等典型PHPT的临床表现，均为体检和并存或误诊为甲状腺疾病时发现。24例患者术前血钙升高18例，正常6例；血磷降低7例，正常17例；16例术前行血甲状旁腺激素检测患者中11例升高，正常5例；22例患者术前测定血碱性磷酸酶升高9例，正常13例。血钙与甲状旁腺激素均正常者4例，其中1例为体检时超声发现甲状旁腺病变，3例为手术治疗甲状腺疾病术中探查发现。24例患者术前均行超声检查，15例行甲状旁腺ECT检查，14例行甲状旁腺增强CT检查，阳性率分别为66.67% （16/24）、93.33% （14/15）及78.57% （11/14）。15例术前定性定位检查获得明确诊断，5例定性或定位检查高度怀疑甲状旁腺病变，4例术前误诊为甲状腺病变。均行甲状旁腺腺瘤切除，其中甲状旁腺腺瘤位于左侧上位2例、左侧下位9例、右侧上位2例、右侧下位11例。肿瘤最大径为（2.22±0.88） cm。24例患者中13例合并甲状腺病变。本组患者术后有8例出现手足、口周麻木，给予静脉或口服补钙后缓解，其余患者均无自觉症状。术后血钙及甲状旁腺激素均有不同程度下降，术后2周均降至正常范围。结论 甲状旁腺腺瘤所致无症状PHPT临床症状不典型，血清钙和甲状旁腺激素同步升高即可诊断，具有手术指征的患者应积极手术治疗。
