Hypothesis: Older patients experience the same benefits from a laparoscopic gastric banding (LGB) operation as younger patients.Design: A case series of 320 morbidly obese and superobese patients who underwent LGB within a 46-month period.

We report the first case of robot-assisted thoracoscopic resection of a mediastinal parathyroid adenoma in the aorto-pulmonary window. Intervention planning was based on preoperative CT-MIBI image fusion, a new imaging modality that enabled reliable and precise localization of the parathyroid. The technique consists of taking MIBI-SPECT and CT separately, using a fixation unit that provides reproducible positioning of the patients head and neck. The data sets are then superimposed upon each other using special software. After the localization process, a minimally invasive operation was performed using the DaVinci operating robot. The procedure proved not only to be feasible but also safe and not time-consuming. The postoperative course was uneventful, and the patient was discharged 4 days postoperatively. Compared to conventional thoracoscopic surgery, the robotic operating system provides better visualization of the operating field and facilitates the movement of the instruments. Precise preoperative imaging enables the careful planning of robot-assisted surgery for ectopic parathyroids located at relatively inaccessible regions such as the anterior mediastinum.

This study provides evidence that CT-MIBI-SPECT image fusion is superior to MIBI-SPECT alone in preoperative localization of enlarged parathyroid glands in patients with hyperparathyroidism and previous neck surgery. This should be kept in mind if the results are compared to earlier studies concerning CT-MIBI-SPECT image fusion.

This study provides evidence that CT-MIBI-SPECT image fusion is superior to CT or MIBI-SPECT alone for preoperative localization of enlarged parathyroid glands in patients with single-gland primary hyperparathyroidism.
