With the widespread introduction of minimally invasive surgery (MIS) in late 1987 by laparoscopic cholecystectomy, the practice and expectation of general surgery were changed forever. As the development of scientific technology, new techniques of MIS have sprung up all around the world. 3D laparoscopy surgery, natural orifice transluminal endoscopic surgery, da Vinci surgical system and other new technologies also need time to be verified, and this is the only way all new things should get though. They are very unique in their own right, and all have advantages and disadvantages...

INTRODUCTION: Conventional two-dimensional (2D) laparoscopy systems have the drawback of poor depth perception and spatial orientation. Three-dimensional (3D) laparoscopic systems have stereoscopic vision in which depth perception is achieved by different unique images received by each eye. We evaluated 3D laparoscopy in comparison with conventional 2D laparoscopy in urological procedures in a prospective randomized study. MATERIALS AND METHODS: Over a 19 month study period, 108 patients scheduled to undergo various urological procedures were randomized to either conventional 2D or 3D laparoscopy (2D n = 53; 3D n = 55)...

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)...
