Keyhole surgery

​

By means of keyhole surgery (laparoscopic surgery) , the operation is performed through a number of small incisions (5 or 12 mm). A working port (trocar) is placed into the abdominal cavity through each of these incisions. A camera is inserted into one of these working ports. Via the camera, the surgeon has an overview of the abdominal cavity without the necessity of  a large incision. Through the other working ports, the operation is performed using a number of instruments specifically designed for keyhole surgery. In order to create enough working space, the abdominal cavity is inflated to a pressure of 12-15 mmHg using CO2 gas.

Benefits of keyhole surgery

​

Keyhole surgery (laparoscopy) is part of the concept of ' minimally invasive surgery'. This means that the operation is performed in the least invasive way possible in order to avoide tissue damage as much as possible. The advantages of laparoscopy over open surgery have already been proven extensively: 

​

- Less pain

- Less blood loss during surgery

- Faster recovery

- Shorter hospital stay

- Limited scars and better cosmetic result

- Less risk of incisional hernia

- Fewer adhesions in the abdominal cavity

Which operations via keyhole surgery

​

Both the gastric bypass and the sleeve gastrectomy are usually performed via keyhole surgery. The vast majority of revisional surgery is also performed via keyhole surgery.

​

​

Robotic surgery is also a form of keyhole surgery and is categorized as 'minimally invasive surgery'.
