Hemicolectomy Colon Removal Surgery

What is Hemicolectomy?

A Hemicolectomy – colon removal surgery, is one in which a side of the colon is removed. There are two types of hemicolectomy, they are right and left colectomy. A right hemicolectomy is a surgical procedure where the right side of the colon is removed and the small intestine is attached to the part of the colon that’s remaining. A left hemicolectomy is the same as right colectomy but the only difference is that in this procedure the left side of the colon is removed. The left side of the colon is attached to the rectum and during the procedure the surgeon attaches the transverse colon directly to the rectum.

Why is the procedure carried?

The procedure is carried out for the following reasons:
  • 1.Colon cancer
  • 2.Bowel cancer
  • 3.Inflammatory bowel disease
  • 4.Crohn’s disease
  • 5.Abnormal tissue growth in the colon that may lead to cancer
  • 6.Diverticulitis, a condition where diverticula in the colon gets infected or inflamed

How to get ready for the surgery?

The doctor will advise a full physical examination before the surgery, to check for any other complication that needs to be addressed before surgery. The doctor will inform the patient about the requirement of having a ‘stoma’ after the surgery. A stoma is an opening in the belly wall that is made during the surgery by the doctor in order for the waste to leave the body, which doesn’t happen if there is no bowel movement through the rectum. The waste from the stoma collects in the colostomy bag. If you have a prior medical condition and you are taking medicines prescribed by a doctor please make sure you inform the surgeon beforehand. If you have a habit of smoking you will be advised to stop smoking a few weeks prior to the date of the operation as smoking may result in other complications or may cause infections resulting in failure of the procedure. Quitting smoking enhances the chances of success. The doctor will prescribe laxatives a few days before the surgery; this will help in clearing out the digestive tract. The patient is required to stop drinking or eating anything before 12 hours of the surgery.

How is the surgery performed?

There are two approaches that the doctor may opt for in order to remove the rectum, open surgery or minimally invasive surgery. The surgery is carried out under the influence of general anesthesia. The patient will be put on IV drip so that there is a constant nutrient supply to his/her body. The doctor will either perform a minimally invasive surgery or an open procedure depending upon the condition of the patient. In an open surgery long incisions are made in the abdomen region and the affected part of the rectum is located, which is then removed. The surgery is carried out under the influence of general anesthesia. The patient will be put on IV drip so that there is a constant nutrient supply to his/her body. The doctor will either perform a minimally invasive surgery or an open procedure depending upon the condition of the patient. In a laparoscopic surgery, once the patient is asleep the process begins by making incisions near the belly button and a small device is inserted which is called a port; it creates an opening that will used be filled with gas (carbon dioxide) in the abdomen region. Through these incisions a Laparoscope (a Laparoscope is a small instrument with a narrow tube which has light source and camera at the end of the tube) is inserted and using the Laparoscope’s video camera the surgeon is able to locate the affected body part and through the other incisions that are made the damaged/affected part (in this case the rectum removed) is removed with the help of surgical equipment; after this the incisions are sealed using a surgical glue or staples. After the cancer ridden part of the rectum is removed, the surgeon joins the healthy ends and staples them. This process is called anastomosis.

Frequently Asked Question's(FAQ's)

1. How Do I Find a Bariatric Surgeon?

Clearly, you want a bariatric surgeon who is very experienced in this specialty area. Research shows that the more experienced the surgeon, the lower the risk of death or complications during or after the surgery. To identify an excellent surgeon, collect a list of names. Ask friends and family members. Ask coworkers. You might be surprised -- lots of people often know others who have had weight loss surgery and want to share their doctor's name.

2. How Will My Physical Appearance Change After Weight Loss Surgery?

As you start losing weight, you will likely be thrilled with your new appearance. However, many people who lose a lot of weight often find their skin looks loose and baggy. You may want plastic surgery to remove this excess skin.

3. Will My Social Life and Relationships Change After Weight Loss Surgery?

Your relationships with friends and family may indeed change after weight loss surgery. For many people, food and drink are the basis for socializing. After weight loss surgery, you must find other ways to socialize -- ways that aren't focused on food.

4. Will I Feel Like Myself After I Lose Weight?

Losing a significant amount of weight is no small matter. In fact, the effects are profound and far-reaching. Life may seem disconcerting at times. You may feel odd, not quite like yourself. You may feel overwhelmed by the lifestyle changes you must make for the rest of your life. You may have reached for food as comfort -- and have difficulty giving it up. A therapist can help you get through this complicated period. A support group can also help. Ask your doctor about support groups for people who have had weight loss surgery. It helps to meet people who are making the same adjustments you're making -- and can help keep you on track with your weight loss program.

5. What Lifestyle Changes Are Necessary After Weight Loss Surgery?

Over time, some people regain weight despite bariatric surgery. Some eat high-calorie or high-fat foods instead of healthy foods -- and eat them too often. Some people rely on "soft meals" such as ice cream and milk shakes. The body itself may change over time, too, leading to weight gain. The digestive tract might begin absorbing more calories. Even the size of your surgical stomach can expand gradually over time.

6. How Much Weight Will I Lose After Surgery?

After gastric bypass surgery, most people can expect to lose between 66% and 80% of their extra body weight. Most of this is lost within the first two years. After gastric banding, people lose 40% to 50% of their extra weight, typically within the first two years after the surgery.
