Does the Lens Deflection Angle Affect Laparoscopic Camera Navigation?

In laparoscopic surgery, a 30° lens is frequently used to obtain a wider field of view. However, it is difficult for inexperienced surgeons to maintain the horizontal state of the image in laparoscopic camera navigation (LCN). If there is a great deviation in the camera's horizontal axis, it may result in ambiguous anatomical recognition, which could impair patient safety.

Open versus mini-invasive partial and radical nephrectomy complications: results from the French national health database.

Background: Laparoscopic surgery is associated with a lower morbidity than open surgery. No recent data compared kidney cancer surgery in the French population using the National Health Insurance database (PMSI-MCO).

Aims: We explore and compare the surgical morbidity rates between laparoscopic and open laparotomy for kidney cancer.
