Minimally invasive surgery for primary hyperparathyroidism: a systematic review.

Area of Science:

• Endocrine Surgery
• Surgical Innovation
• Evidence-Based Medicine

Background:

• Primary hyperparathyroidism management often involves parathyroidectomy.
• Minimally invasive techniques offer potential advantages over traditional open surgery.
• Systematic review needed to evaluate safety and efficacy of minimally invasive parathyroidectomy (MIP).

Purpose of the Study:

• To systematically review literature on safety and efficacy of MIP.
• Compare unilateral or endoscopic exploration with bilateral open neck exploration.
• Assess outcomes of MIP in primary hyperparathyroidism patients.

Main Methods:

• Literature search of MEDLINE, EMBASE, Current Contents, and Cochrane Library (up to August 1998).
• Search terms included variations of 'minimally invasive', 'endoscopic', 'unilateral', and 'parathyroidectomy'.
• Inclusion of human studies comparing MIP with bilateral open neck exploration; animal studies on technique development also included.

Main Results:

• Data analysis favored the unilateral technique, but with large confidence intervals (CI).
• Certainty in preferring the unilateral procedure is limited due to wide CI.
• Potential selection bias exists due to strict enrollment criteria for unilateral surgery.

Conclusions:

• MIP is proposed for primary hyperparathyroidism patients with unilateral parathyroid pathology.
• Monitoring MIP introduction via a trial in Australia is suggested.
• Data accrual to a register is recommended to assess safety and efficacy thoroughly.
