Abstract

Introduction:

Primary hyperparathyroidism is one of the most common endocrine disorders requiring surgical parathyroidectomy for its definitive treatment. Surgical exploration is traditionally performed through conventional open neck approach. A wide range of minimal access and minimally invasive endoscopic techniques (gas less and with gas) have been attempted in the past two decades. In this context, we evaluated the feasibility and safety of an innovative transoral endoscopic parathyroidectomy (EP) technique, which represents a paradigm shift in transluminal endocrine surgery.

Materials and Methods:

This is a prospective study conducted at a tertiary care Endocrine Surgery Department in South India between May 2016 and August 2017. We employed a novel transoral, lower vestibular route for EP. All the clinical, investigative, operative, pathological and post-operative data were collected from our prospectively filled database. Statistical analysis was performed with SPSS 20.0 version.

Operative Technique:

Under inhalational general anaesthesia, access to the neck was obtained with 3 ports (central frenulotomy and two lateral port sites), dissected in subplatysmal plane and insufflated with 6 mm Hg CO2for working space. Rest of surgical steps is similar to conventional open parathyroidectomy.

Results:

Out of the 38 hyperparathyroidism cases operated during the study, 12 (32%) were operated by this technique. Mean operative time was 112 ± 15 min (95-160). The post-operative course was uneventful with no major morbidity, hypocalcemia or recurrent laryngeal nerve palsy. Cure and diagnosis were confirmed by> 50% fall in intraoperative parathyroid hormone levels and histopathology (all were benign solitary adenomas).

Conclusions:

Through this study, we opine that this novel transoral vestibular route parathyroidectomy is a feasibly applicable approach for primary sporadic hyperparathyroidism, especially with solitary benign adenomas.
