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.
Objective To summarize the changes of serum vitamin D level in patients with primary hyperparathyroidism (pHPT), the correlation between vitamin D and clinical manifestations, and feasible pathogenesis of pHPT. Method The literatures related to vitamin D and pHPT in recent years were reviewed. Results The level of vitamin D was decreased in patients with pHPT. Vitamin D level was negatively correlated with the weight of parathyroid adenoma, parathyroid hormone and blood calcium level, and positively correlated with bone mineral density. Conclusions Vitamin D nutritional status affects the severity of symptoms, main biochemical indexes and main clinical complications of patients with pHPT. There are various reasons accounted for the decline of vitamin D level, and the specific pathogenesis needs to be further explored. For patients with pHPT, vitamin D should be supplemented carefully and appropriately before surgical operation.
Objective To summarize the research progress of the treatment of primary hyperparathyroidism (PHPT) in multiple endocrine neoplasm type 1 (MEN1). Method The literature about the treatment of PHPT in MEN1 in recent years was reviewed. Results When the symptoms of MEN1 related PHPT were obvious, surgery was an effective treatment. In addition to conventional total parathyroidectomy with autotransplantation and subtotal parathyroidectomy, less-than subtotal parathyroidectomy, and single gland excision had also been proved to be effective recently. Conclusions Combining the clinical manifestations with the actual involvement of the parathyroid of MEN1 related PHPT patients, personalized selection of appropriate timing and methods of parathyroidectomy can help MEN1 related PHPT patients obtain ideal parathyroid function and ensure the quality of life to the greatest extent.
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.
