Minimally Invasive Parathyroidectomy as the Surgical Management of Single Parathyroid Adenomas: A Tertiary Care Experience

The aim of our study is to assess the feasibility, safety and adequacy of focused parathyroidectomy for single parathyroid adenoma accurately localized preoperatively by ultrasound neck and Tc99m sestamibi scan. The study was conducted in the department of Otorhinolaryngology of SMS Medical College and Hospital, Jaipur on 116 patients of primary hyperparathyroidism who underwent minimally invasive parathyroidectomy (MIP) for single gland adenoma localized by USG neck and tc99m sestamibi scans. S. Calcium and S. PTH followed up on day 1, 6th week and 6th month. Outcomes were determined on the basis of cure rate, duration of hospitalization, complication rates and disease persistence/recurrence rate. 82 (70.68%) females and 34 (29.31%) males belonging to the age group of 21–67 years (43.02 ± 14) formed the basis of our study. Skeletal (73.27%) and renal (62.93%) were the most common presentations. Accuracy of USG and sestamibi accurately was 93.10% and 96.55% respectively with combined accuracy of 100%. Preoperative serum calcium levels of 10.7–16.03 mg/dl (13.09 ± 2.11) and serum PTH 127–2196 pg/ml (846.57 ± 776.55) were observed. Cure rate of MIP was 99.13%. No permanent complications seen. MIP can be used as the surgical procedure of choice for PHPT caused by single gland adenoma aided by USG and sestamibi scan. The cure rates are equivalent to the bilateral neck exploration (> 95%) with minimal morbidity and complications. Hence, it is a more feasible, safe and effective treatment option.
