Dr. Pandelidis studies surgical interventions and diagnostic processes related to managing primary hyperparathyroidism and breast lesions. He has investigated minimally invasive parathyroidectomy, a less invasive surgical option for treating an overactive parathyroid gland, which can lead to various health issues. In addition, he analyzes the accuracy of biopsies used to detect breast abnormalities, such as atypical ductal hyperplasia and ductal carcinoma in situ, focusing on the reliability of these methods to ensure patients receive appropriate treatment.
Key findings
In a study of 111 minimally invasive parathyroidectomies, the success rate was 98.2%, with only 2 patients experiencing complications post-surgery.
The accuracy study found that 13.2% of ductal carcinoma in situ cases and 13.5% of atypical ductal hyperplasia cases were underestimated by the 11-gauge vacuum-assisted biopsy.
The likelihood of missing invasive cancer increases significantly when the targeted breast lesion is a larger area of calcifications, greater than 1.5 cm.
Frequently asked questions

Plain English This study looked at a type of surgery called minimally invasive parathyroidectomy (MIP) to treat primary hyperparathyroidism, performed at a community hospital without measuring hormone levels during the operation. Out of 111 MIP surgeries done, only 2 patients had issues afterward, giving a high success rate of 98.2%. This matters because it shows that MIP can be done effectively even without certain intraoperative tests, making the procedure simpler for both patients and surgeons.

Plain English The study looked at how accurate an 11-gauge vacuum-assisted biopsy is for detecting certain breast conditions, specifically atypical ductal hyperplasia (ADH) and ductal carcinoma in situ (DCIS). Researchers found that this type of biopsy underestimated the severity of the disease in 13.2% of DCIS cases and 13.5% of ADH cases. It was particularly likely to miss invasive cancer when the targeted lesion was a larger area of calcifications, greater than 1.5 cm, highlighting the importance of careful monitoring for these patients.
Who this helps: This information benefits doctors and patients undergoing breast biopsies, especially those with DCIS or ADH.
