ABSTRACT
BACKGROUND: Uniportal robotic-assisted thoracic surgery (uRATS) has emerged as a promising technique with potential advantages over multiportal approaches. This study aims to evaluate our initial outcomes of uRATS. MATERIAL AND METHODS: Five patients underwent anatomic lung resections with systematic nodal dissection through a uniportal robotic approach by one surgeon. The results were compared to the results of the first five uniportal video-assisted thoracic surgery (uVATS) anatomical resections performed by the same surgeon. RESULTS: No adverse events occurred during the uRATS-procedures. Comparable surgical outcomes were observed between uRATS and uVATS, including hospital stays, complication rates, and blood loss. The average procedural time was slightly but non-significantly longer in the uRATS-group. Average pain-scores were lower in the uRATS group. One patient in each group experienced major postoperative complications, with one case of in-hospital mortality in the uRATS-group. CONCLUSION: The outcomes of uRATS/uVATS were comparable, highlighting the potential and the feasibility of this technique. Prospective studies comparing the learning curves, complication rate and hospital-stay are required in order to justify the superiority of robotics over uVATS.
ABSTRACT
BACKGROUND AND AIMS: Intraoperative localization of pathologic parathyroid glands is of major importance for the hyperparathyroidism treatment. Based on the small size and the anatomic variability, the localization can be very challenging. The current practice is to compare preoperative ultrasonography with Technetium-99m sestamibi scintigraphy (MIBI) and plan the resection accordingly. In this study, we implemented indocyanine green angiography for the intraoperative localization of parathyroid glands. MATERIALS AND METHODS: This is a retrospective analysis of 37 patients with primary, secondary, or tertiary hyperparathyroidism who were operated using indocyanine green angiography for the intraoperative localization of pathological parathyroid glands. An indocyanine green solution of 2.5 mg was were intravenously administered for parathyroid gland visualization. Different fluorescence scores were correlated with changes in postoperative parathyroid hormone levels. RESULTS: Patients were divided into two groups depending on the presence of uniglandular or multiglandular disease. Sixty-four lesions were resected, and the final histopathologic analysis confirmed the parathyroid origin in 62 of them (96.8%). None of the patients with uniglandular disease developed postoperative hypoparathyroidism, whereas three patients in the multiglandular group developed temporary hypoparathyroidism symptoms. Indocyanine green imaging had higher sensitivity for the intraoperative detection of parathyroid glands compared with ultrasonography and MIBI (p < 0.001). CONCLUSION: Indocyanine green angiography indicated high sensitivity for the intraoperative identification of pathologic parathyroid glands leading to a resection rate of 95.16%. The modality was useful, especially in cases of revisional surgery or ectopic parathyroid glands. Randomized trials have already proven the value of indocyanine green imaging in predicting postoperative hypocalcemia. Our results support the regular use of this method during parathyroid surgery.
