Traditionally, operations on the colon and rectum required a large abdominal and/or pelvic incision, which often required a lengthy recovery. New instrumentation and techniques allow the surgeon to perform the procedure through several small incisions, what we now refer to as “minimally invasive”, “laparoscopic”, or “laparoscopic-assisted” colorectal surgery.
Colorectal conditions that can be treated laparoscopically include:
Symptoms of colorectal diseases include bleeding from the rectum, abdominal pain, change in bowel habits (new diarrhea, constipation, stool size, etc.), weight loss, anemia, cramping, vomiting, fever, among many others. Prior to undergoing surgery, your primary doctor or your surgeon will usually do tests (blood work, colonoscopy, barium enema, CT scan, etc.) to decide the cause of your symptoms. If you are found to have a disease that requires surgery, that is when a laparoscopic colorectal operation will be considered.
Minimally invasive or laparoscopic surgery involves using multiple trocars (thin tubes) placed through 3 to 5 small incisions. These incisions are usually less than 0.5 cm (less than ¼ inch). Carbon dioxide gas is then used to slowly inflate the abdomen. A thin telescope is placed through one of the trocars. This allows the surgical team to view the inside of the abdomen on a TV monitor. Specialized instruments are placed through the other trocars to perform the operation. For colon surgery, one of the incisions is enlarged to remove the piece of colon. This larger incision can also be made initially, allowing one hand to be placed within the abdomen along with the camera and long instruments to assist with the operation. The procedure is performed under general anesthesia.
Results are different for each procedure and each patient. Some common advantages of minimally invasive colorectal surgery are:
Many patients qualify for laparoscopic or minimally invasive surgery. However, some conditions may decrease a patient’s eligibility, such as previous abdominal surgery, cancer (in some situations), obesity, variations in anatomy or advanced heart, lung or kidney disease.
Before you go to surgery, you will need to be evaluated by your primary doctor and your surgeon. You may need further tests such as a colonoscopy, barium enema, EKG, chest x-ray, CT scan of the abdomen, and/or blood work. Your surgeon or primary doctor will order these tests.
Preparation for colon or rectal surgery will require cleansing of the colon or “bowel prep”. Your surgeon may recommend an enema, a prescribed beverage for bowel preparation and/or some antibiotics. A bowel preparation should be followed by only a liquid diet and no solids for 8 hours prior to surgery. You may be instructed to stop taking certain home medications. These include blood thinners, warfarin, aspirin and ibuprofen. You should notify your surgeon of ALL current medications during your evaluation . Patients are usually admitted to the hospital the day of surgery.
You will meet with the anesthesiologist and an intravenous catheter will be placed in your arm for delivery of fluids and medication during your surgery. This procedure is performed under general anesthesia, which means you will be completely asleep. As soon as you are asleep, catheters are placed through the nose into the stomach and in the bladder and the surgical team will work together to perform the operation. Monitors are used to observe your vital signs throughout the surgery. When the operation is complete the breathing tube is removed. Most patients do not remember this. You are then taken to the recovery room for a short stay.
After your surgery is done, you will be taken to the Post-Anesthesia Care Unit, or PACU. You will be there for 1-2 hours. When you are ready, you will be moved to your hospital room where your family will be able to see you. The nurses will continue to check your heart rate, blood pressure, temperature, breathing and your incision.
They will also be checking your tubes:
For pain control, there may be a pump attached to your IV. This is called a PCA or patient controlled analgesia pump. You will have a button that you push when you start to feel it’s time for pain medicine. The pump is set so that you cannot get too much medicine. Often you will use this pump until you are able to eat and take pain medicine by mouth. The compression devices will stay on your legs while you are in bed during your hospital stay to lessen your risk of blood clots.
That afternoon or, at the latest, on the first day after your surgery, you will be helped out of bed to sit in a chair. By the second day, you will need to walk in the hallway. Walking helps lessen your risk of getting a lung infection or blood clots. It also speeds up your recovery.
You will not be able to eat or drink anything at first. You may be given some ice chips at times. Once the NG tube is removed, you will start on a clear liquid diet the next day. Your diet will be changed each day, as you are better able to eat foods.
Complications are possible with any surgical procedure. The following are some complications related to laparoscopic colorectal surgery:
If the operation cannot be completed laparoscopically, the surgeon will make a traditional, larger incision. Reasons for this include bleeding and the inability of the surgeon to clearly view the operative area. This should never be considered a failure, but rather a prudent decision by the surgical team to safely complete the operation.
These guidelines give you an overview of what you may expect as part of your care after you leave the hospital. Be sure to follow your doctor’s discharge instructions if they are different from what is listed here.
It is fairly common to feel weak and tired immediately after discharge from the hospital. The body needs time to recover from the stress of a major operation.
Walking is permitted and encouraged beginning the next day after surgery. At home, start short, daily walks and gradually increase the distance you walk.
Going up and down stairs is permitted. Initially, have someone assist you.
You may lift light objects (less than 10lbs.) after your discharge. This may be increased gradually after one month. If lifting an object causes discomfort, you should discontinue the activity. This restriction helps prevent hernias at the sites of your incisions.
Showers are permitted 2 days after surgery. Wash over your incisions gently with soap and water. Be careful to rinse well. Pat the incisions dry.
Driving is not permitted for 2 weeks after surgery or your first follow-up visit with your surgeon. If you are taking prescription pain medications or narcotics, DO NOT DRIVE.
Sexual intercourse may be resumed as your comfort level permits.
Return to work
People with sedentary jobs have returned to work as early as two weeks postoperatively. A physically demanding job may require 4-6 weeks before returning to work. This may be determined by you and your employer. Some people have residual fatigue several weeks after surgery.
You may have different bowel habits after your surgery. Loose stools are common for the first week or two after surgery. If you have watery diarrhea, call your surgeon. This may be a sign of a bowel infection. Severe constipation should be avoided. See the section below on medicines for constipation.
There are generally no dietary restrictions following surgery. Avoid foods that cause diarrhea or digestive discomfort. You will eventually be able to resume your regular diet. A dietary supplement or drink can be used.
Your medicines: Take the medicines you were taking before surgery, unless your doctor has made a change. For pain: Your surgeon will order a prescription pain medicine for you after surgery. As your pain lessens, over the counter pain medicines such as acetaminophen (Tylenol) or ibuprofen (Advil) can be used. They can also be used instead of your prescription for mild pain. For constipation: Prescription pain medicines can cause constipation. Your doctor may order docusate (Colace) as a stool softener to prevent this. You should be back to your normal bowel routine in about 2 weeks. If the stool softener does not work, take Milk of Magnesia. If you still are not getting relief, call your surgeon.
Call your doctor's office right away if you have:
In order to identify and treat any complications as they may arise, close, lifetime follow-up is essential. Follow-up after surgery is extremely important. Patients usually make an appointment to see their surgeon 2 weeks after discharge. At this visit, further plans are made and the patient may be cleared for full activities such as driving.
