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.
ObjectiveTo assess the clinical efficacy of percutaneous transplantation of parathyroid glands into the subcutaneous tissue of the epigastrium for treating malignant secondary hyperparathyroidism (SHPT). MethodsThe clinical data of the patients with SHPT who were treated by puncturing the subcutaneous tissue of the epigastrium and transplanting parathyroid glands in the Xuzhou Central Hospital from January 2020 to June 2022 were collected retrospectively. The preoperative and postoperative parathyroid hormone (PTH) level, calcium ion concentration, alkaline phosphatase (ALP) level, and phosphorus ion concentration, as well as postoperative follow-up results were analyzed. The data analysis was conducted using SPSS 23.0 software, with a testing level of 0.01. ResultsA total of 21 patients successfully underwent this surgery, including 12 males and 9 females, with a median age of 48 years old and a range of 32–71 years old. The dialysis time was (8.62±2.27) years, and 12 patients had hypertension, 9 patients had anemia, 17 patients had bone pain, and 11 patients had skin itching. On day 1 after treatment, the PTH level decreased from (1 893.23±539.30) ng/L to (5.99±3.50) ng/L (P<0.001), the calcium ion concentration decreased from (2.52±0.31) mmol/L to (2.24±0.35) mmol/L (P=0.003), and the phosphorus ion concentration decreased from (2.25±0.71) mmol/L to (1.76±0.38) mmol/L (P=0.006) as compared with the values before surgery. Although the ALP level decreased from (321.78±151.01) U/L to (229.32±89.32) U/L, there was no statistically significant difference (P=0.016). Among the 12 patients with hypertension before surgery, 6 patients improved and reduced the use of antihypertensive drugs after surgery; among the 9 patients with anemia, 3 patients improved before discharge; 17 patients with bone pain showed markedly relief before discharge; and 9 patients with skin itching improved before discharge. There were no complications such as hoarseness, choking cough when drinking water, or incision infection after the operation. All 21 patients were followed up for 6–12 months. The parathyroid hormone levels of the 21 patients all dropped to the normal level within 12 months after the operation. Among them, 3 patients recovered to the normal level at the 3rd month after the operation, 16 patients recovered to the normal level at the 6th month after the operation, and 2 patients recovered to the normal level at the 12th month after the operation. The time to return to the normal level was (5.86±2.70) months. No serious complications occurred in all patients, and there was no recurrent case during follow-up period. Conclusion From the analysis results of our study, parathyroid autotransplantation into the subcutaneous tissue of the epigastrium via puncture is a safe and effective method for patients with SHPT.
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 investigate the significance of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT in the diagnosis of primary hyperparathyroidism, and its relationship with the level of serum calcium (CA).
MethodsThe clinical data of 73 patients with parathyroid dysfunction (serum parathyroid hormone (PTH) > 130 pg/mL) were retrospectively analyzed. The 99Tcm-MIBI SPECT double phase imaging were performed in 73 cases, 63 cases underwent cervical B-ultrasound examination, and 16 cases underwent CT examination. According to the serum calcium (CA) levels, the patients were divided into CA < 2.7 mmol/L group and CA > 2.7 mmol/L group, and the postoperative pathological examination and followed-up results were as the standard, the sensitivity, specificity, positive predictive value, and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT for diagnosis of PHPT in different serum CA levels were compared.
ResultsThe sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 87.6%, 81.8% and 35.7%, respectively; the specificity was 87.5%, 75.5% and 50.0%, respectively; the positive predictive value was 98.2%, 93.7% and 83.3%, respectively; and the negative predictive value was 46.7%, 33.3% and 10%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging and B-ultrasound examination for diagnosis of PHPT were significantly higher than those of CT examination(P < 0.05). The sensitivity, specificity, positive predictive value and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging for diagnosis of PHPT were higher than those of B-ultrasound examination, but the difference was not statistically significant (P > 0.05). In the CA < 2.7 mmol/L group, the sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 91.1%, 84.7% and 37.9%, respectively; the specificity was 80.2%, 72.9% and 49.7%, respectively; the positive predictive value was 96.8%, 96.0% and 79.4%, respectively; and the negative predictive value was 50.0%, 37.5% and 10.0%. In the CA > 2.7 mmol/L group, The sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 87.9%, 83.9% and 42.8%, respectively; the specificity was 83.3%, 79.2% and 50.0%, respectively; the positive predictive value was 96.9%, 94.1% and 75.0%, respectively; and the negative predictive value was 50.0%, 40.5% and 20.0%. There were no significant difference in the diagnostic accuracy between the 3 methods and the level of serum CV in different levels.
ConclusionsThe diagnostic accuracy of 99Tcm-MIBI SPECT dual-phase imaging and B-ultrasound examination for diagnosis of PHPT patients with PTH > 130 pg/mL (especially parathyroid adenoma) were higher than that of CT examination, and it is not associated with the serum CA concentration.
ObjectiveTo summarize the research status of normocalcemic parathormone elevation after parathyroidectomy for patients with primary hyperparathyroidism.
MethodsThe related literatures on normocalcemic parathormone elevation after parathyroidectomy were collected and reviewed.
ResultsMost of the patients with primary hyperparathyroidism received radical treatment postoperation. NPE didn't predict failure of operation. The relationship between normocalcemic parathormone elevation and recurrent primary hyperparathyroidism remained to be further explored. Patients with normocalcemic parathormone elevation after parathyroidectomy had a higher risk of cardiovascular disease. Postoperative vitamin D and calcium supplementation could reduce the incidence of normocalcemic parathormone elevation.
ConclusionsThe clinical significance of normocalcemic parathormone elevation is still unknown at present. Further researches of multicenter, huge sample, and long-term follow-up will be necessary.
Objective To investigate the clinical value on application of endoscopic parathyroiddectomy by gasless unilateral axillary approach, and perioperation management of patients. Methods Twenty-four patients with primary hyperparathyroidism were enrolled and were divided into open group (14 patients underwent open parathyroid surgery) and lumpectomy group (10 patients underwent endoscopic thyroidectomy by gasless unilateral axillary approach) according to the surgical method. All patients received the “5A” model management. The indexes related with perioperative conditions, postoperative incisional pain, and anterior cervical function were compared between the two groups. Results In the open group, 1 patient suffered from transient hoarseness after operation, 5 patients suffered from hypocalcemia on the first day after operation, and 6 patients suffered from temporary hypoparathyroidism. In the lumpectomy group, hypocalcemia occurred in 3 cases and temporary hypoparathyroidism occurred in 3 cases. There were no incision hematoma and infection cases occurred. There was no significant difference between the two groups in the incidence of hypocalcemia and the incidence of temporary hypoparathyroidism after operation (P>0.05). There was no case of incisional hematoma and infection, incisional pain, coughing and sputum excretion or painful swallowing with pain ≥3 in either group. The swallowing disorder index on postoperative day 3 and at 6 months, the scar assessment score and cosmetic satisfaction score at 6 months were higher in the open group than those in the lumpectomy group (P<0.05). Conclusion Patients underwent parathyroidectomy by gasless unilateral axillary approach have the advantages of good cosmetic results and preservation of the function of the anterior cervical region while safely removing the lesion.
ObjectiveTo summarize the mechanism, risk factors, clinical manifestations, and medical treatment of hungry bone syndrome (HBS) in patients with hyperparathyroidism after parathyroidectomy, and to provide clinicians with reference for disease diagnosis and treatment.MethodThe related literatures about HBS in patients were collected and reviewed with clinical experience.ResultsHBS was a group of clinical syndromes mainly manifested as hypocalcemia after parathyroidectomy in patients with high bone turnover state before operation, with a high incidence, and the main purpose of treatment was achieved by supplementing calcium and vitamin D.ConclusionsHBS requires reasonable diagnosis and timely treatment by clinicians. Patients can achieve long-term blood calcium and phosphorus stability and bone mass growth through medical treatment.
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.
ObjectiveTo analyze the factors influencing the hungry bone syndrome (HBS) in patients with secondary hyperparathyroidism (SHPT) after parathyroidectomy. MethodsThe clinical data of patients who underwent parathyroidectomy for SHPT in the 900th Hospital of the Joint Logistics Support Force from January 2016 to May 2021 were retrospectively analyzed. The risk factors for HBS were analyzed by binary logistic regression analysis. The cut-off value of risk factors for predicting postoperative HBS was analyzed by using recieve operating characteristic (ROC) curve. ResultsA total of 89 patients were included in this study, including 44 males and 45 females, with (47±11) years old. There were 42 (47.2%) patients with HBS. Compared with the patients without HBS, the patients with HBS was younger and had higher levels of preoperative parathyroid hormone, potassium, and alkaline phosphatase (ALP), the differences were statistically different (P<0.05). The multivariate binary logistic regression analysis showed that the higher preoperative ALP level was a risk factor for the HBS [OR (95%CI) = 1.014 (1.007, 1.020), P<0.001]. The area under the ROC curve (95%CI) of the preoperative ALP level in distinguishing the patients with HBS from without HBS was 0.957 (0.919, 0.996), and the optimal cut-off value of ALP for predicting postoperative HBS was 278.90 U/L. ConclusionsFrom the preliminary results of this study, it can be concluded that bone conversion status can be differentiated according to preoperative ALP level in patients with SHPT. When preoperative ALP level is higher than cut-off value, it is recommended that calcium supplementation should be given as soon as possible and blood calcium level should be closely monitored.
