Colon biopsy question. How often does the biopsy cause a hole in your intestine?

Colon perforation: The most feared complication of a colonoscopy or colon biopsy is the risk of perforation--inadvertently cutting through the entire thickness of the bowel wall. This complication used to occur in about 1 in 1000 persons undergoing the procedure. With improved techniques and instruments, the risk is now about 1 in 5000. ...Read more

Intestine (Definition)

The gastrointestinal tract starts at the mouth, travel down the tunnel (esophagus), which connects to the stomach, which then empties into the duodenum, jejunum, and ileum---the three parts of the small intestine (@25 feet). This empties into the colon or large intestine (about 5 feet), which then becomes the sigmoid colon, rectum and out the anus. So, every morsel eaten ...Read more

I have an adenomatous polyp on the valve between the large and small intestines in a fold. Biopsy showed not cancer. What is the best way to remove it?

I have an adenomatous polyp on the valve between the large and small intestines in a fold. Biopsy showed not cancer. What is the best way to remove it?

Excesion: Excision and complete removal of the adenomatous tissue is considered the treatment of choice. There are several techniques for polyp removal; biopsy forceps, snare excision, fulguration and piecemeal excision of large polyps. The procedure depends of the location, surgery, laparotomy, Laparoscopy, sigmoidoscopy. The use of NSAD has been shown to significantly reduce the size and number . ...Read more

Can a doctor via colonoscopy see the level of inflammation in the intestines? Does it require a biopsy? Are there any blood tests that can determine?

Can a doctor via colonoscopy see the level of inflammation in the intestines? Does it require a biopsy? Are there any blood tests that can determine?

Not really: Colonoscopy can reveal masses and polyps (larger issues). If you are looking at tissue lining inflammation, or 'leaky gut' syndrome, there are several labs that have kits to test for this either by blood or by stool analysis. If it's to determine Chron's or Ulcerative colitis, there are other blood, GI tests, endoscopic imaging, ultrasound, (blue) dye during colonoscopy looking for inflammation. ...Read more

What is a bowel transplant? Does that include both the colon and small intestines? I see that it's a rare operation, how come?

What is a bowel transplant? Does that include both the colon and small intestines? I see that it's a rare operation, how come?

Complex : This is rare, and often done as part of multiple organ transplant. Usually due to an intraabdominal catastrophe where there is loss of the intestines due to lack of blood supply from a variety of causes. This is only done in specialized transplant centers. Hope this helps! ...Read more

Can you tell me if a benign tumour arises in the small intestine (duodenum) would it cause abdominal pain and weight loss just as a malignant tumour would?

Can you tell me if a benign tumour arises in the small intestine (duodenum) would it cause abdominal pain and weight loss just as a malignant tumour would?

Yes it can: Benign tumors around the duodenum can produce hormones that may cause weight loss by causing diarrhea. A benign tumor can ulcerate and cause bleeding in the intestine and if unresolved can cause weight loss. ...Read more

If small cell lung cancer grows so quickly, why is the primary often difficult to visualise on CT with contrast? Is the primary slow growing? Thanks.

If small cell lung cancer grows so quickly, why is the primary often difficult to visualise on CT with contrast? Is the primary slow growing? Thanks.

Observation: It is not clear why small cell lung cancer can have larger secondaries than the primary lesion. But it is a common observation and metastatic lesions/secondaries may be the first manifestation of this cancer and the primary may be difficult to visualize. It is not due to the slow growth rate of the tumor. ...Read more

If a colonscopy can reach the small intestine, why would the dr also want to do an endoscopy through the stomach to the sm bowel as well to biopsy all?

If a colonscopy can reach the small intestine, why would the dr also want to do an endoscopy through the stomach to the sm bowel as well to biopsy all?

Different Areas: The colonoscopy may reach the end of the small bowel whereas the upper endoscopy reaches the start of the small bowel. Even though they both reach the small bowel those areas function differently. Also the upper endo allows for biopsy of the stomach and esophagus if needed. Need for these scopes depends on the condition being evaluated. ...Read more

Suppose someone have tomour in colon and it caused near small bowel also narrows in CT enterography does image can distinguise this narowing is not caused from small bowel itself?

Not exactly: sure of the question, but generally a mass won't be mistaken for a normal bowel loop on a CT scan, particularly a CT san tailored to evaluate the small bowel loops like CT enterography. ...Read more

Hi, i had a upper GI endoscopy. They found mucosal nodularity in the fundus. What does this mean? Is it an indication for ulcer? And is it something c

Hi, i had a upper GI endoscopy. They found mucosal nodularity in the fundus. What does this mean? Is it an indication for ulcer? And is it something c

Possibilities...: I understand your concern but, like many things in medicine, a single physical finding taken out of context can suggest nonspecifically a variety of phenomenon. Fundic nodularity may indicate hyperplasia, inflammation, an inflltrative process (like lymphoma), more. Rather than worry needlessly, please wait to hear your biopsy results, then treat objectively. ...Read more

Child had colonoscopy done which showed some prominent lymphoid tissue in the descending colon. What does this mean?

Child had colonoscopy done which showed some prominent lymphoid tissue in the  descending colon. What does this mean?

Inflammation: Prominent lymph tissue usually signals some type of inflammation. Deciding what is causing the inflammation is the more difficult aspect here. It could be post-infectious (after a viral GI infection), could be a more systemic infection like mono, could be allergies/food sensitivities....The list goes on. Need to work closely with peds GI to determine if clinically significant and identify cause. ...Read more

Can a colonoscopy prep cause irritation in the colon in the internal rectum that looks exactly like Ulcerative Colitis when the pictures are taken.

Can a colonoscopy prep cause irritation in the colon in the internal rectum that looks exactly like Ulcerative Colitis when the pictures are taken.

Not likely: Ulcerative colitis has a specific appearance and location that distinguishes it histologically from normal tissue. The scenario you describe is possible with human error involved, but for the most part, very unlikely ...Read more

What does it mean to have, as an adult, a "rather large" amount of lymphatic tissue in the nasopharynx? Nasal channels "normal" after endoscopy.

What does it mean to have, as an adult, a "rather large" amount of lymphatic tissue in the nasopharynx? Nasal channels "normal" after endoscopy.

Adenoid hypertrophy: It sounds like your ENT likely saw large adenoids on nasal endoscopy. The adenoid pad is formed by lymphatic tissue and exists on the back wall of the space behind your nasal cavities. Adenoid enlargement is common in young children but unusual in adults. Causes can include chronic infection (common) HIV, lymphoma, or other tumor. Your ENT could perform a biopsy if it looked at all suspicious. ...Read more

How much of the colon is examined during a colonoscopy?

How much of the colon is examined during a colonoscopy?

All of it!: The intention with colonoscopy is to examine the entire length of the colon. Sometimes due to tortuosity (or twisty-ness), it is difficult or impossible to see the entire colon. Other ways to evaluate the colon include virtual colonoscopy and barium enema. The advantage of colonoscopy is if anything is found, it can be biopsied or removed often times right away. ...Read more

Biopsy (Definition)

Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more
