Identifying intersegmental planes is considered the key step during segmentectomy. Several techniques, including modified inflation-deflation techniques, target-segment jet ventilation, and infrared-fluorescence-enhanced methods, have been reported for the identification of intersegmental planes. However, limitations of these methods have also been reported. Here, we described an improved collateral ventilation method to identify the inflation-deflation line without waiting and without any auxiliary materials needed during robotic-assisted anatomic segmentectomy. We present this handy technique of identifying the intersegmental planes and comment on its advantages, including decreased operative time and improved clarity of the inflation-deflation line.

Background: Near-infrared fluorescence (NIF)-mapping with indocyanine green dye (ICG) facilitates the identification of the intersegmental plane during minimally invasive segmentectomy. Our pilot study showed that ICG is associated with an increase in oncological margin distance from the tumour, greater than the surgeon's best judgment. We hypothesized that, with greater experience, the surgeon's judgement will improve, and the benefit of ICG will diminish.

An athlete's performance and musculoskeletal health hinges on their ability to adapt their movements to varying environmental constraints. However, research has yet to offer a thorough understanding of whether coordination variability is altered in response to different synthetic and natural turf surfaces. The purpose of this study was to investigate lower extremity coordination variability during hopping and running on four turf surfaces-three synthetic and one natural.

The plane running between two adjacent pulmonary segments consists of a very thin layer of connective tissue through which the pulmonary vein also runs. To perform an anatomically correct segmentectomy, this segmental plane needs to be divided. Before the operation, the locations of vessels and bronchi are confirmed by three-dimensional computed tomography.

Background: Anatomical liver resection has been altered by a deeper understanding of the internal structure of the liver, highlighting the importance of the intersegmental plane, a region lacking Glissonean branches. These insights have enabled a novel surgical technique focused on the precise detachment of the intersegmental plane, supported by indocyanine green (ICG) fluorescent imaging and robotic platforms, enhancing the precision and safety of liver resection.
Methods: This study involved four patients who underwent robotic left hepatectomy using the Da Vinci Xi system.
