Laparoscopic Surgery

This is also known as Keyhole Surgery. Using small holes between the sizes of 5mm to 15mm, surgeons can perform many operations which in the past requires big wounds. This means less pain for the patient, faster recovery, shorter hospital stay and faster return to usual activities.


It is becoming the standard way of surgery for many conditions including gallstones, hernia and colon cancer.


In the past, surgical operations for diseases of the abdomen would be done via an open cut in the abdomen. After the operation, the patient usually has significant pain from the big wound. This pain results in them staying in bed longer, as getting out of bed is painful and difficult. The hospital stay becomes longer. There is also a higher risk of wound problems such as infection and hernia. The scar is also longer and more obvious. There is a greater degree of internal scarring, called adhesions, which can lead to future problems such as bowel obstruction and frequent abdominal pain.


In 1985, Prof Dr Erich Mühe, a German surgeon, performed a keyhole operation to remove the gallbladder. Using 4 small holes ranging in size from 5mm to 10mm, he removed the gallbladder. If he did it the using traditional open technique, the wound would be about 10 to 15cm long.

Advantages of the laparoscopic or keyhole operation
  • Less pain
  • Shorter stay in hospital (after keyhole operation for gallbladder removal, the patient only stays one night)
  • Able to get out of bed earlier and walk
  • Able to return to usual activities such as work or social activities earlier
  • Better cosmesis as the scars are very small
  • Less adhesions (internal scars)
  • Less wound complications

In the early 1990s, laparoscopic surgery was introduced to Singapore. Today, laparoscopic surgery has become the standard operation for many conditions.
