Uterine artery pseudoaneurysms (UAP) are rare but potentially life-threatening lesions. They may occur after traumatic deliveries, cesarean sections, and other interventions. We present a case of a 39-year-old woman with a UAP. The patient was accurately diagnosed using ultrasound imaging, with subsequent diagnostic hysteroscopy and laparoscopic excision of the UAP. In the present case, a ligation of the artery branch was performed to provide accurate hemostasis during UAP dissection. The vascular lesion was partially enucleated and removed, followed by recreation of the previous uterine shape...

INTRODUCTION: Studies have shown that using robotic-assisted laparoscopy (RL) increases performance compared to conventional laparoscopy (CL) due to its mechanical advantages but have not assessed distraction as a factor. To determine whether the immersive aspect of the 3D optics in RL contributes to improved performance, we compared the outcomes of laparoscopic skills by using just the 3D optics of the da Vinci versus the conventional 2D monitor with and without distraction. METHODS: Thirty-two participants without any laparoscopic experience were randomized evenly into four groups: RL, robotic-assisted laparoscopy with distraction (RL + D), CL, and conventional laparoscopy with distraction (CL + D)...

PURPOSE: For safe and reliable laparoscopic surgery, it is important to determine individual differences of blood vessels such as the position, shape, and branching structures. Consequently, a computer-assisted laparoscopy that displays blood vessel structures with anatomical labels would be extremely beneficial. This paper details an automated anatomical labeling method for abdominal arteries and veins extracted from 3D CT volumes. METHODS: The proposed method represents a blood vessel tree as a probabilistic graphical model by conditional random fields (CRFs)...
