Remote mentoring in laparotomic and laparoscopic cancer surgery during Covid-19 pandemic: an experimental setup based on mixed reality.

In this paper, Mixed Reality (MR) has been exploited in the operating rooms to perform laparoscopic and open surgery with the aim of providing remote mentoring to the medical doctors under training during the Covid-19 pandemic. The employed architecture, which has put together MR smartglasses, a Digital Imaging Player, and a Mixed Reality Toolkit, has been used for cancer surgery at the IRCCS Hospital 'Giovanni Paolo II' in southern Italy. The feasibility of using the conceived platform for real-time remote mentoring has been assessed on the basis of surveys distributed to the trainees after each surgery.

Experimental Setup Employed in the Operating Room Based on Virtual and Mixed Reality: Analysis of Pros and Cons in Open Abdomen Surgery.

Currently, surgeons in operating rooms are forced to focus their attention both on the patient's body and on flat low-quality surgical monitors, in order to get all the information needed to successfully complete surgeries. The way the data are displayed leads to disturbances of the surgeon's visuals, which may affect his performances, besides the fact that other members of the surgical team do not have proper visual tools able to aid him. The idea underlying this paper is to exploit mixed reality to support surgeons during surgical procedures.

An Intrapancreatic accessory spleen presenting as a neuroendocrine tumor.

Although the second most common site of the accessory spleen is the tail of the pancreas, intrapancreatic accessory spleens (IPAS) are rarely recognized radiologically. When an accessory spleen is located in the pancreas, it may mimic a hypervascular pancreatic tumor. We report a case of intrapancreatic accessory spleen which radiologically (on TC) mimicked a neuroendocrine pancreatic tumor (PNET).

Intestinal perforation secondary to blunt abdominal trauma in pre-existing inguinal hernia.

Inguinal hernias are very common in men. We report a rare case of intestinal perforation following blunt abdominal trauma in a 80-year-old man with pre-existing inguinal hernia. A careful and serial physical examination, with the information obtained from the computed tomography (CT) scan guides the prompt surgical exploration.

Retrorectal multilocular cyst in a adult female. Case report and review of literature.

Tumors occurring in the retrorectal space are heterogeneous and uncommon. Multiple embryologie remnants derived from a variety of tissues are found in this space and this explains the heterogeneous pathology of cysts and tumors that arise in retrorectal space. Presacral cysts are rare in adults.
