Minimally Invasive or Laparoscopic Colorectal Surgery
Understanding the Procedure

Before the surgical field had all the technological advancements it has today, most operations on the colon and rectum had to be done the traditional way. This required surgeons to make large incisions on the abdomen and/or pelvis area that may cause patients a lengthy recovery period. Today, new techniques and instruments allow surgeons to perform the same procedures using only several small incisions; this is what we now refer to as “minimally invasive” or “laparoscopic” colorectal surgery.

Minimally Invasive Surgery Minimally Invasive Surgery

Minimally invasive or laparoscopic surgery involves several thin tubes - also called trocars - placed through 3 to 5 small incisions that is usually less than 0.5 cm in size. Afterwards, carbon dioxide gas is used to steadily inflate the abdomen before a laparoscope - a thin, hollow tube with a video attached to the end - is inserted through one of the trocars, allowing the surgical team to view the inside of the abdomen on a TV monitor. This procedure is performed under general anesthesia which means the patient will be completely asleep during the process.


Since this procedure is performed under general anesthesia, you will be asleep during the entire duration of the surgery. Specialized instruments are used to ensure your safety all throughout the surgical process. An intravenous catheter will be placed in the arms to deliver fluids and medication as well as catheters through the nose, stomach and bladder. Aside from this, monitors will be used to observe your vital signs.

If you are suffering from colorectal diseases or conditions such as Colon cancer, diverticulitis, and polyps, your surgeon may require you to undergo laparoscopic colorectal surgery.

The following symptoms may suggest that you suffer colorectal diseases:

  • Bleeding from the rectum
  • Abdominal pain
  • Change in bowel habits
  • Weight loss
  • Anemia

Once you observe that you are experiencing the symptoms above, it is a must that you consult your doctor right away to avoid further complications.

Smaller Wounds

Minimally invasive colorectal surgery has been used commonly over the recent years for their advantages over conventional surgery. They include

  1. Since the procedure involves only small incisions, you will experience less postoperative discomfort;
  2. You can also expect less pain when the procedure is done and a reduced risk of infection;
  3. It won’t take long before you can go back to your usual diet and activities; and lastly
  4. Better cosmetic healing (= smaller and less obvious scars).
