Up until now, the removal of bowel tumors in the lesser pelvis (rectal cancers) involved a major, generally invasive operation. This operation can now be done in a much gentler way using an innovative procedure, robotic surgery. Thanks to a better three-dimensional view of the operating area and robotic instruments that allow highly accurate surgery to be performed in the anatomically constricted space of the lesser pelvis, surgical trauma and incisions for the operation can be kept to a minimum, while, at the same time, achieving excellent surgical results.
