When a part of the large intestine or colon gets affected by cancer, the process of removing that part by surgery is called Hemicolectomy.
It is mainly required to treat the cancer of vowels or the type of Crohn's disease. The surgical process includes the removal of the infected area of the bowel and replacing it with a new part which may be grafted from the skin or an artificial implant.
It is mostly an advanced measure that is taken when the part of the colon cannot be cured by the means of any medicinal measure. It also depends on how much the damage is and the extent of infection in the colon.
When a person is suffering from some acute condition of the stomach then he or she is an eligible candidate for Hemicolectomy.
Mostly in the case of bowel cancer, doctors prefer to use the surgical technique of hemicolectomy. The conditions of ulcerative colitis also make the patient an ideal candidate for the procedure of hemicolectomy. The other conditions include Crohn's disease, polyps or growths, and diverticulitis.
The polyp growth in the stomach is the one that requires close attention as they don’t normally get cured by the traditional medicinal procedure. There are several methods that can achieve hemicolectomy and these are based on the complications of the patient.
Following are the factors which influence the cost of hemicolectomy:
The last part of the gastrointestinal system is referred as the colon and it is 5-6 cm long. It is ‘U’ shaped and it starts from the distal part of the small intestine and is connected to the rectum and anus. It absorbs the fluids, processes the metabolic waste products, and eliminates through the rectum and anus. The removal of the colon is called colectomy.
There are different types of colectomies such as complete colectomy, right hemicolectomy, left hemicolectomy, sigmoid colectomy, and proctocolectomy. The surgical removal of the left side of the colon (descending colon) is called left hemicolectomy surgery. The surgical removal of the cecum, ascending colon, and the hepatic flexure (right side of the colon) is called as the right hemicolectomy surgery.
Some of the conditions that require complete colectomy or hemicolectomy surgery include the following:
A hemicolectomy procedure can be performed as a laparoscopic or open surgery. The type of the surgery to be performed is decided by the surgeon during the evaluation and the decision depends on the age and the condition of the patient.
Sometimes the laparoscopic procedure can also be turned into open surgery, depending on the feasibility of the procedure with respect to safety and accuracy. Overall, the following parameters decide whether a laparoscopic or an open surgical procedure will be performed:
You will be informed by your surgeon about the type of surgical procedure that you will benefit you the most. You will be taken to the operating room, and blood pressure and breathing will be monitored.
You will be positioned in lithotomy Trendelenburg (modified Lloyd-Davis) position and your both arms will be abducted on arm boards. The legs will be placed in stirrups and soft padding will be placed underneath to prevent pressure and injuries to the skin and nerves.
After positioning, you will be given general anaesthesia so that you do not feel any pain during the procedure. Sometimes, a peripheral nerve block may also be given to control pain during and after the surgery.
You will be positioned in the supine position initially and later you may be taken to the Trendelenburg position (lying by facing upwards on a tilted bed with pelvis higher than the head).
After positioning, you will be administered general anaesthesia and an additional epidural block for pain management. The catheter will be placed for monitoring the urine output during and after the procedure. The laparoscopic right hemicolectomy procedure or open surgery can be performed, depending on the condition of the colon.
During the hemicolectomy procedure, your surgeon may take any of the following approaches:
