Summary

 

Side Effects of Surgery

  • Pain Management
    • Pain control is important in the healing process.  It is important to stay ahead of the pain.

    • The time it takes to heal after surgery is different for each person. You may be uncomfortable for the first few days. Medicine can help control your pain.

    • Before surgery, you should discuss the plan for pain relief with your doctor or nurse.

    • After surgery, your doctor can adjust the plan if you need more pain relief. Do not be concerned about becoming addicted to pain drugs. Studies indicate addiction doesn’t happen in these circumstances. (To learn how to deal with pain, see Pain 101).

  • Ostomy and Stoma
    • When a section of your colon or rectum is removed, the surgeon can usually reconnect the healthy parts. However, sometimes reconnection is not possible. In this case, the surgeon creates a new path for waste to leave your body. The surgeon makes an opening, a stoma, in the wall of the abdomen, connects the upper end of the intestine to the stoma, and closes the other end. The operation to create the stoma is called a colostomy. A flat bag fits over the stoma to collect waste, and a special adhesive holds it in place.

    • For many people, the stoma is temporary. It is needed only until the colon or rectum heals from surgery. After healing takes place, the surgeon reconnects the parts of the intestine and closes the stoma. Some people, especially those with a tumor in the lower rectum, need a permanent colostomy.

    • People who have a colostomy may have irritation of the skin around the stoma. Your doctor, your nurse, or an enterostomal therapist (a professional trained in ostomies) can teach you how to clean the area and prevent irritation and infection. (For information about minimizing risk of infection in your day-to-day life, click here).

  • Urinary Function

    • With a rectal resection, urinary function may change because the nerves may be bruised during the surgery. While the loss of urinary control is generally not permanent,  some patients will need a urinary catheter for longer than usual, medication, or both on a temporary basis.
  • Fatigue. It is common to feel tired or weak for a while. To learn how to cope with fatigue, click here.
  • Constipation/Diarrhea:
    • Surgery sometimes causes constipation or diarrhea.  Your health care team monitors you for signs of bleeding, infection, or other problems requiring immediate treatment. (For information about how to avoid infection on a day-to-day basis, click here).

    • Do what you can to avoid becoming constipated short of using an enema which can hurt the rectum if used within three months after surgery. For example, your doctor may prescribe a stool softener or laxatives for several days after the operation.

  • Sexual Function   
    • Men:  
      • A resection can cause “dry” orgasms with no ejaculation by damaging the nerves that control ejaculation. Alternatively, the result could be “retrograde ejaculation” – the semen goes backward into your bladder. With both dry orgasms and retrograde ejaculation a man can still get an erection. With retrograde ejaculation, a man can still father a child because doctors can recover sperm cells from urine or from testicles with minor surgery. The sperm is then used to impregnate a woman by means of in vitro fertilization.
      • It is possible that a resection may stop erections totally or the ability to reach orgasm.  There are alternatives to permit sex. See Erectile Dysfunction.
  • Women: There is generally no loss of sexual function, though the vagina may become dry or  irritated for a while which can cause painful intercourse. In some cases the change is permanent.

 

Follow Up:

  • Follow up visits will be scheduled for removal of the staples and to check incision for healing, to discuss results and next steps.
  • There will be another visit 4 – 6 weeks later.
  • After that, there will be quarterly follow-up visits with your surgeon . 




Laparoscopy (Laparoscopic Surgery)

Laparoscopy is minimally invasive surgery which can accomplish the same result as more invasive traditional surgery by using a thin, lighted tube known as a laparascope. Any segment of the colon or rectum may be removed with a laparoscopy. Studies show that even obese patients and patients who have had prior surgery can have this surgery.

  •  With a laparascopy, the incision is 2 inches or 3 or 4 tiny cuts of a quarter to one half inch in the abdomen instead of an 8-12 inch incision. (One of the incisions is used to inject carbon dioxide into the abdomen. The carbon dioxide separates the abdominal wall so the surgeon can operate). Sometimes only one small opening (port) is involved. (This is known as the No Visible Scar or Single Port Approach). The No Visible Scar approach moves the single cut to the area below the pubic hair line.
  • The surgeon sees inside your body on a video monitor by manipulating the laparoscope. He or she does the same procedure as in open surgery. (See the above Section). (create link to above section)
  • Rectal surgery using laparoscopy generally takes 3 – 6 hours.
  • The risks and complications are generally about the same as for open surgery. Complications are significantly higher for surgeons who do not have adequate training or do not do a large number of these procedures.
  • Most institutions doing the open surgery also use the laparoscopic technique.

Laparoscopic operations were first performed in 1991.

There are both short term and long term benefits to laparoscopy compared to traditional surgery.

  • In the short term:
    • Recovery is faster and easier because of the smaller incision:
    • There is less pain.
    • Less pain medicine is needed.
    • People can take deep breaths easier and get out bed and walk a lot sooner.
    • Less time is required for bowel function to be recovered.
    • People tend to do better in the hospital. For example, people can be fed pretty much right away, with something to drink and to advance the diet. People can generally leave the hospital within 3 – 5 days after the operation. 
    • Less blood loss.
    • Better quality of life.
  • In the longer term:
    • Recovery at home is usually about 2 weeks compared to 6 to 8 weeks of recovery needed after a regular operation.

NOTE: There is no improvement in cancer treatment or change in the rate of long term survival with laparoscopic versus open surgery. Doctors have noticed that patients with laparoscopies have less scar tissue so we may start seeing less problems with bowel obstruction due to scar tissue and may start seeing lower incidence of hernia formation in patients having laparoscopies.

A determination whether a patient is a candidate for a minimally invasive surgery depends on several factors:

  • The skill and training of the surgeon.
  •  The disease progression
  • The body weight of the patient. A patient who is morbidly obese (a BMI of more than 40) has a less likelihood of successfully being treated with a minimally invasive approach.
  • Patients with severe inflammatory bowel disease or severe diverticulitis may or may not be able to be treated with laparoscopy. 

Most health insurance policies cover laparascopic surgery. At the least, policies pay the same as for an open operation. (How much a policy pays is generally a problem for the surgeon’s staff rather than for the patient).

Robotic Surgery for Rectal Cancer

Robotic surgery is the removal of the rectum using a minimally invasive high tech robotic instrument in a hospital.  It is particularly useful for rectal surgery because of the tiny pelvic nerves around the rectum. Use of the robot helps reduce sexual and bladder problems. 

The procedure:

  • Unlike robots like R2D2, robotic instruments are controlled by a surgeon who controls every action of the surgical robot.
  • The procedure is much like a laparoscopy. 3 or 4 robotic instruments are inserted into the abdomen through small incisions. The surgeon controls the movements of the robotic instruments.
  • Robotic instruments are more precise and flexible than conventional laparoscopic tools and the surgeon’s view is 3 dimensional.
  • The procedure usually takes about 2 hours from start to finish. 
  • General anesthesia is used so there is no pain during the procedure and less pain afterwards than either open or laproscopic resection.
  • Close to 90% of patients leave the hospital within 24 hours.  A few patients need an extra day – usually just for safety reasons.

Preparation for Robotic Surgery:

  • Stop aspirin and blood thinners  7 – 10 days before surgery to avoid bleeding problems during the surgery.
  • Herbs , vitamins or supplements that may cause bleeding should be stopped at least 10 days to 2 weeks before the operation.
  • There is no need to bank your blood before the operation because blood loss is usually just a few tablespoons.

Recovery from Robotic Surgery:

  • An advantage of robotic surgery is that it is better at sparing sensitive nerves that are involved in erectile and bladder functioning and the anal sphincter.
