Objective: To study and compare the specific postoperative complications of thyroidectomy in a population with a BMI R25 with a population having a BMI below 25. Design: A prospective study was carried out from September 2010 to January 2013. Methods: Postoperative calcemia, laryngeal mobility, bleeding or infectious complications, postoperative hospital stay, and operation time were studied and compared statistically by a c 2 -test or Student's t-test.Results: A total of 240 patients underwent total thyroidectomy and 126 underwent a partial thyroidectomy. Of them, 168 patients had a BMI below 25 and 198 patients had a BMI R25. There was no statistically significant difference in the occurrence of early or permanent hypoparathyroidism, recurrent laryngeal nerve palsy, bleeding complications, or postoperative duration of hospital stay. There was, however, a significant operative time in patients with a BMI R25. Conclusion: Despite the longer operative time, thyroidectomy (total or partial) can be performed safely in patients with a BMI R25.

ARS is not a predictive score efficient enough in a French population maybe due to different metabolic data and genetic conditions.

Objectives: The parathyroid cysts (PCs) are rare and their diagnosis and therapeutic management are not clearly established. The aim of the study was to evaluate the characteristics of parathyroid cysts. Methods and Materials: Twenty-five patients with PC were included in this retrospective study. The PCs were discovered as follows: cervical mass (n = 18), screening for other pathologies (n = 7). Intracystic parathyroid hormone determination was performed in 6 cases. Results: Eight patients presented a hyperparathyroidism. Mean cyst size was 21.1 mm (ext 4 -70 mm) by 19.8mm (5 -45 mm). Twenty four cysts were cervical (resection by cervicotomy), and one was mediastinal (resection by sternotomy). In addition to the resection of the PC, 3 adenomas, 1 hyperplasia of the parathyroid glands, 14 benign thyroid diseases and 4 papillary carcinomas were recognized and treated during the cervicotomies. Conclusion: The diagnosis of PC is uncommon and must be based primarily on the study of the cyst liquid obtained by percutaneous puncture (intracystic parathyroid hormone measurement). True PCs are non functional.
