A laparoscopy involves two cuts approximately 5-10mm long. The first cut is made just below the navel. A hollow needle is inserted. This is then connected to a supply of carbon dioxide gas, which is pumped through the needle and into the abdomen. This lifts the wall of the abdomen away from the organs inside, making it easier and safer to insert the laparoscope and examine the internal organs.
The procedure uses a laparoscope. This is a long thin instrument with a light source at its tip, to light up the inside of the abdomen or pelvis. Fibre optic fibres carry images from a lens, also at the tip of the instrument, to a video monitor, which the surgeon and other theatre staff can view in real time.
The laparoscope is inserted through a second small cut made on the abdomen. The exact position depends on the reason for the procedure. For instance, women having a gynaecological investigation will usually have the incision in the belly button. This minimises visible scarring.
General anaesthetic following an operation can make you feel drowsy, nauseous, thirsty and weak, so plenty of rest afterwards will be recommended. It is natural to worry about such things but this is a routine procedure and you will be in and out in no time, possibly without even knowing anything much about it.
