Technique for ectopic intrathymic parathyroid adenoma: the uniportal subxiphoid approach

[Management of primary hyperparathyroidism with rare localization of ectopic adenoma parathyroid gland]

Topical diagnosis can be severely complicated in patients with primary hyperparathyroidism (PHPT) due to the ectopic placement of parathyroid gland (PTG) formations. We report a clinical case of PHPT in an 84-year-old patient caused by ectopic PTG adenoma located behind the right internal jugular vein at the level of the right submandibular gland. The impossibility of surgery for a long time due to the absence of a topical diagnosis has necessitated conservative treatment was required to get the hypercalcemia under control. In view of the concomitant deficiency of vitamin D, an attempt was made to use therapy with saturating doses of cholecalciferol under dynamic monitoring of the indicators of phosphorus-calcium metabolism, which allowed to achieve a significant decrease in PTH levels while maintaining normocalcemia.

Clinical Application of Thoracoscopic Resection of Anterior Mediastinal Tumors under the Xiphoid Process

Objective

To explore the feasibility and advantages of thoracoscopic resection of anterior mediastinal tumors through subxiphoid and lateral thoracic approaches.

Method

74 patients with anterior mediastinal tumors hospitalized in our hospital from January 2019 to January 2022 were retrospectively analyzed. They were divided into the lateral chest group (31 cases) and the infraxiphoid group (43 cases) according to different operation methods. The tumor size, operation time, intraoperative bleeding, postoperative pain score, postoperative complications, postoperative drainage tube removal time, and hospital stay were compared between the two groups.

Result

The intraoperative bleeding and postoperative pain scores in the subxiphoid group were better than those in the lateral chest group. There was no significant difference in operation time and postoperative complications between the two groups.

Conclusion

Compared with the lateral thoracic approach, the thoracoscopic subxiphoid approach can be more safe and effective in resectioning anterior mediastinal tumors.
