Summary
Minimally invasive video-assisted thyroidectomy (MIVAT) shows a significant learning curve. With experience, MIVAT reduces operative time and complications, making it a viable thyroid surgery option.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Endocrine Surgery
Background:
- Minimally invasive video-assisted thyroidectomy (MIVAT) is an emerging surgical technique.
- MIVAT requires a dedicated learning period for surgeons to achieve proficiency.
Purpose of the Study:
- To evaluate the impact of surgical experience on MIVAT outcomes.
- To assess the learning curve associated with MIVAT.
Main Methods:
- A retrospective analysis of 100 MIVAT procedures performed between July 2005 and December 2006.
- Patients were grouped based on case number (1-25, 26-50) and cumulative experience (1-50, 51-100).
Main Results:
- Operative time significantly decreased from 101.7 min (cases 1-25) to 84.6 min (cases 26-50) (p < 0.03).
- Further reduction in operative time was observed from 91.07 min (cases 1-50) to 63.06 min (cases 51-100) (p < 0.004).
- Complications, including hypocalcemia and nerve palsy, decreased with increasing surgical experience.
Conclusions:
- The MIVAT procedure demonstrates a clear learning curve, with significant improvements after the initial 25 cases.
- Increased experience with MIVAT leads to reduced operative times and fewer complications.

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
