This study compares two tools used during thyroid removal surgery: LigaSure and bipolar diathermy. The goal is to see which one leads to shorter surgery time, less pain, and fewer complications. Thirty adults having partial or total thyroid removal will take part.

This study tests a computer vision model called PTAIR that helps surgeons identify parathyroid glands and recurrent laryngeal nerves during endoscopic thyroid surgery. About 100 adults with thyroid disease will take part. The model's ability to spot these structures will be compa…

This study will measure how much of the pesticide chlordecone is stored in the thyroid and nearby fat tissue of 69 adults having thyroid surgery in Guadeloupe. Researchers will also look at blood levels and ask about diet and job history to see what factors affect accumulation. T…
