- difficult handling of the instruments
- very restricted mobility
- difficult hand-eye coordination
- no tactile perception

This is the most frequently done minimally-invasive operation. The endoscopic
camera is put in the abdoman through the navel, the instruments through
small incisions with approximately 5-15 mm diameter. In the upper left corner, the endoscopic view is displayed.
Endoscopic procedures in the human abdoman are also called 'laparoscopy'.
