Laparoscopic surgery is commonly called “minimally invasive” surgery because it involves smaller incisions than traditional open surgery. Incisions are typically 0.5-1 cm, compared with several inches for open surgery. Laparoscopic surgery is a latest advancement in the field of all the types of abdominal cancers- esophageal, gastric, pancreas, liver, gall bladder and bile ducts, colon & rectum and appendiceal.
The only difference between the classical open and laparoscopic surgery is in the approach of entering inside abdomen. The extent of surgery remains same in both the methods and people must not think that in laparoscopic surgery cancer is not taken out completely.
For the procedure, your stomach is inflated with carbon dioxide gas to create a visual field and enough room for your surgeon to work. At the outset, surgeon makes a small incision near your belly button and inserts a special camera known as a laparoscope. The purpose is to make sure the operation can be done safely. Certain conditions, such as a large amount of inflammation, may obscure your surgeon’s view and require a larger incision to operate safely.
Doctor then makes other small incisions, or ports, and passes instruments shaped like tubes through each port. These instruments are long and narrow, and have clamps, scissors and sutures at the end. Surgeon the use these instruments throughout the surgery to manipulate, cut and sew tissue while watching the video from the laparoscope on high-resolution monitors in the operating room.
The advantages of laparoscopic surgery over open surgery may include:
- Shorter recovery time
- Less pain
- Less scarring
In some situation, surgeons opt to create a port large enough to insert their hand during the operation. This technique is called hand-assisted laparoscopy. It requires a port larger than typical laparoscopic incisions, but still smaller than the incision made during open surgery.
