Looping was both more frequent ( P = 0.0002) and less well tolerated in women than in men ( P = 0.0140). Conclusions: This study is the first to document pain at colonoscopy accurately. Looping, particularly in the variable anatomy of the
Thinner and more flexible endoscopes may cause less stretching of the mesentery, which is one of the principal sources of pain during colonoscopy.
Loops or angulation in the colon are possibly the most common patient-related source of difficulty. Some bends require additional skill to navigate. Loops, particularly in the sigmoid colon, can result in loss of control of the endoscope as well as patient discomfort.
Everyone's experience is different, but you can rest assured that the colonoscopy itself is painless. You will receive anesthesia so that you don't feel pain or remember the procedure. Most centers use medications that stop working quickly. That means you shouldn't feel any lingering side effects.
Pain after the colonoscopy
It is normal to experience some stomach pain after the procedure, usually because the air causes gas. This sensation may be mild or intense, but it typically only lasts an hour or two. Some people experience mild stomach pain for a day or two after the procedure.
What if I've taken all my preparation and am still passing solid stool on the day of my exam? In this case, your procedure will need to be rescheduled. You may be prescribed a different preparation for your next procedure. Please call the triage nurse to reschedule your procedure with a different preparation.
During the test
You don't normally need medication to make you relax while you have the test. The endoscopist will first check your back passage for any abnormalities. They then gently put the colonoscope into your back passage and up into the large bowel. This is uncomfortable but is not usually painful.
The mechanism of pain during colonoscopy is similar to that of childbirth. Both are caused by the spasm of smooth muscle. But the pain during colonoscopy is artificially caused by the insertion of endoscope.
After the test, you may be bloated or have gas pains. You may need to pass gas. If a biopsy was done or a polyp was removed, you may have streaks of blood in your stool (feces) for a few days. Problems such as heavy rectal bleeding may not occur until several weeks after the test.
It will normally only go as far as the first part of the colon, this is known as the caecum. The colonoscope tube is thin and flexible and ranges from 125 centimetres (48 inches) to 183 centimetres (72 inches) in length.
When applied properly, abdominal pressure can help shorten the length of the procedure, minimize the angle of turns in the colon, and minimize discomfort to the patient. A Mayo physician survey unanimously concluded that abdominal pressure is beneficial during colonoscopy.
The sedation levels during the procedures may also differ. Endoscopies can be performed with minimal sedation, while colonoscopies typically require general anesthesia to ensure the patient is comfortable and relaxed throughout the process.
Is a sedation-free colonoscopy painful or uncomfortable? Most patients report little or no discomfort during the procedure. You can request sedation during the procedure if you change your mind and feel you need it, although it has been my experience that this seldom occurs.
Due to the sedation, it is unlikely the patient will remember the colonoscopy itself. Once the procedure is over, the patient will need about 30-60 minutes to recover from the sedation before getting dressed and leaving the building.
The procedure is made more difficult if patients have longer colons, and we know that women in general have a deeper transverse colon, which can make that part of the colonoscopy more challenging; therefore, colonoscopy can be more challenging in women because the female pelvis is wider and deeper than the male pelvis.
You may need a catheter (fine plastic drain tube) put in your front passage to drain the urine from your bladder until you are able to pass urine comfortably on your own.
The night before your surgery, wash with soap you were given. Do not shave your abdomen (stomach) or pubic hair. Shaving before your surgery gives you a higher chance of getting an infection. A person from the health-care team will use clippers to get you ready for surgery if hair needs to be removed.
Most colonoscopies take only 15-30 minutes to complete. As a reminder, most patients recall feeling minimal to no pain or discomfort during the procedure. After the colonoscopy is done, you will be observed in a recovery area until the effects of the anesthesia wear off.
As a general rule, it is best to take the rest of the day off from work after a colonoscopy and give yourself 24 hours to feel 100% normal again.
The First 24 Hours of Recovery
Because a colonoscopy is performed with the patient under the effects of sedation, the patient will need to arrange for a ride home. Once they are at home, patients should allow themselves at least 24 hours to rest and recover.
