Purpose: Thyroidectomy is the treatment of choice for malignant thyroid diseases as well as for benign conditions who cannot be treated medically. The most common complication following thyroidectomy is hypocalcaemia and hypoparathyroidism that usually results from accidental damage or removal of one or more parathyroid glands. Parathyroid gland autotransplantation has been one of the most common intraoperative strategies applied to tackle this problem.

Multiple factors have been linked with increased risk of anastomotic leak in bowel surgery, including infections, inflammatory bowel disease, patient comorbidities and poor surgical technique. The aim of this study was to investigate the positive effect, if any, of adipose derived mesenchymal stem cells (MSCs) mixed with platelet-rich plasma (PRP) in the healing of bowel anastomoses, in an inflammatory environment after establishment of experimental colitis. Thirty-five male Wistar rats were divided into five groups of seven animals: normal controls, colitis controls, PRP, MSCs, and PRP+MSCs.
