44 Laparoscopic and Robotic-Assisted Surgeries need for true dimensions arises, this view does not suffice. There are several minimally invasive procedures which require real-time measurements : 1. Sleeve Gastrectomy : during sleeve gastrectomy, the stomach is resected in proximity to the pylorus. It is essential that this resection is 2cm below the pylorus. Too close may lead to a tear, and too far may lower the success rate of the procedure. 2. Intestine Resection : procedures like Roux-en-Y gastric bypass, bilio- pancreatic diversion, or gastrectomy for oncological purposes require resection of the intestine. Here the surgeon wants to avoid bile reflux on the one hand and malabsorption on the other hand, so the length of the resected portion must Laparoscopic and Robotic-Assisted Surgeries (RAS) are taking up a larger portion of the surgical activity world-wide. Thischangeisaresultof theaccuracyofsuch procedures which leads to superior clinical outcomes. Both are performed using video cameras for visualization - a good solution for visibility in the close confinement of the peritoneal cavity. However, when the INTRA-OP VIRTUAL MEASUREMENTS IN LAPAROSCOPIC AND ROBOTIC-ASSISTED SURGERIES
