Objective To compare the clinical features and surgical effect between ectopic and orthotopic parathyroid lesions. Methods The clinical data of 136 patients with parathyroid lesions who had undergone parathyroidectomy between May 2010 and May 2017 were retrospectively analyzed. Results The ectopic parathyroid location was detected in 20 patients (14.7%) of the 136 patients with parathyroid lesions. Of the 20 patients, prevalence of superior mediastinal ectopic lesions accounted for 30.0% (6/20), prevalence of thyrothymic ligament accounted for 20.0% (4/20), prevalence of intrathymic accounted for 15.0% (3/20), prevalence of tracheoesophageal groove accounted for 25.0% (5/20), prevalence of submandibular accounted for 5.0% (1/20), prevalence of carotid sheath accounted for 5.0% (1/20), respectively. Patients with ectopic lesions had significantly higher level of serum parathyroid hormone (PTH) and alkaline phosphatase (AKP) than patients with orthotopic parathyroid lesions (P≤0.05). In addition, osteitis fibrosa cystica of metabolic bone disease was significantly more frequent in patients with ectopic parathyroid lesions than those with orthotopic parathyroid lesions (P=0.04). Preoperative ultrasonography had a sensitivity of 50.0% (10/20) for ectopic lesions and 90.1% (100/111) for orthotopic lesions. Preoperative 99Tcm methoxyisobutylisonitrile (99Tcm-MIBI) had a sensitivity of 100% (19/19）for ectopic lesions and 95.3% (101/106) for orthotopic lesions. Preoperative CT had a sensitivity of 81.3% (13/14) for ectopic lesions and 93.6% (102/109) for orthotopic lesions. Preoperative combination examination had a sensitivity of 100% (20/20) for ectopic lesions and 99.1% (108/109) for orthotopic lesions. Of the 20 patients with ectopic leisions, 17 patients (85.0%) had undergone 1 time of operation, 2 patients (10.0%) had undergone twice operations, 1 patient (5.0%) had undergone trice operations. The onset of hypocalcemia happened in 13 patients (65.0%) after operation. Of 116 patients with orthotopic leisions, only 1 patient had twice operations, the onset of hypocalcemia happened in 74 patients (63.8%) after operation. The reoperation rate of orthotopic leisions was lower than that of patients with ectopic leisions (P=0.01), but there was no significant difference on the incidence of hypocalcemia (P=0.92). Excessive bleeding and recurrent laryngeal nerve injury didn’t happen after all operations. Of 136 patients, 111 patients had followed-up, among which 17 patients with ectopic leisions and 94 patients with orthotopic leisions. During the followed-up period, there were no recurrence happened. Conclusions The ectopic parathyroid lesions are associated with higher serum PTH and AKP levels and more frequent metabolic bone disease in comparison with the orthotopic parathyroid lesions, as well as high reoperation rate. Combined examination, including cervical ultrasonography, 99Tcm-MIBI, and cervical enhanced CT are needed for preoperative location. Parathyroid lesions resection is the main surgical approach, and patients with parathyroid lesions are prone to be onset of hypocalcemia.
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.
