- Background: Minimal invasive laparoscopic resection of liver tumors is less traumatic compared with open surgical resection and may be a better option for many patients. However, localization of intrahepatic tumors remains a challenge. Availability of hybrid operating rooms, equipped for high performance radiologic imaging, allows for new methods of surgical navigation. Methods: Twelve patients planned for laparoscopic resection of liver tumors were included. Before resection started, tumors were marked with radiopaque fiducials. Four fiducials were positioned with ultrasound within 1 cm of the tumor. Tumor and fiducials were localized with contrast enhanced cone beam computed tomography. Fluoroscopy with an overlay of cone beam computed tomography markings was projected side-by-side on the same screen as the laparoscopic view to visualize tumor location. The fiducials were eventually removed. Laparoscopic ultrasound, the standard method of localizing a tumor, was also used. The benefits of the 2 visualization methods were estimated by the operator. Procedure times, radiation doses and resection margins were recorded. Results: Fluoroscopy with radiopaque fiducials provided valuable information, complementing the laparoscopic ultrasound, particularly during the early phase of resection. In the later phase, mobilization of the tumor-containing liver segment caused significant displacement of the fluoroscopic overlay. The technique evolved during course of the study, with decreasing procedure times and radiation doses. Radical resection was achieved for all patients. Conclusions: Radiopaque fiducials and fluoroscopy can complement laparoscopic ultrasound for guiding resection of liver tumors. Combining radiologic and optical imaging in a hybrid operating suit may facilitate development of augmented reality techniques for surgical navigation. Copyright © 2021 The Author(s).

- AIM: The aim of this study was to survey the occurrence of musculoskeletal disorders in the population of gynecologists and general surgeons performing laparoscopic surgery. METHODS: A questionnaire was distributed to 558 general surgeons and gynecologists and 378 were answered (68%). Descriptive data analysis and statistical calculations were performed. RESULTS: One or more disturbing symptoms were common among laparoscopists. More than 70% of the laparoscopists had one or more symptom. Pain was the most common symptom followed by fatigue and stiffness. Lower back, neck, and shoulders were most frequently affected. Headache and visual discomfort were also reported. Longer workload over time and ageing resulted in significantly more disorders (P<0.01). Female physicians had significantly more disorders (P<0.01). CONCLUSIONS: This study revealed musculoskeletal disorders in a majority of laparoscopists. The laparoscopic technique often requires static and tiring work positions, sometimes extreme, which can explain musculoskeletal disorders among general surgeons and gynecologist.
