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)...

Ultrasonography, especially 3D, is essential in the diagnosis and preoperative evaluation of gynecologic surgeries and is important in surgical planning and counseling of patients. In addition, it is useful during hysteroscopic procedures, particularly difficult Asherman syndrome cases, resection of transverse vaginal septum, and treatment of hematometria. 3D ultrasound is especially helpful for fibroid mapping as the simultaneous visualization of the endometrium and myometrium with the coronal view is possible, it can be done by the gynecologist and at a lower cost than an magnetic resonance imaging...

REVIEW
Emre Huri, Mehmet Ezer, Eddie Chan
Laparoscopic surgery is routinely used to treat many urological conditions and it is the gold standard treatment option for many surgeries such as radical nephrectomy. Due to the difficulty of learning, laparoscopic training should start outside the operating room. Although it is a very different model of laparoscopic training; the aim of this review is to show the value of human cadaveric model for laparoscopic training and present our experience in this area. Fresh frozen cadaveric model in laparoscopic training, dry lab, cadaveric model, animal models and computer based simulators are the most commonly used models for laparoscopic training...
