Recurring large amount of dark rectal bleeding Inc. Large Blood clots. Colonoscopy showed only internal hemorrhoid. OK to assume blood only due to it?

Recurring large amount of dark rectal bleeding Inc. Large Blood clots. Colonoscopy showed only internal hemorrhoid. OK to assume blood only due to it?

Unlikely : The bleeding is probably from diverticulosis or something known as an arterio-venous malformation (AVM). Since these can be anywhere in the colon, if surgery is ever needed to remove that section, it is important to find the exact location with a variety of imaging tests, usually only helpful during a bleeding episode. Hope this helps! ...Read more

CT SCAN ABD/PELVIS W/O CONTRAST:WHAT IT MEANS?BOWEL:ORAL CONTRAST IDENTIFIED IN SMALL AND LARGE BOWEL LOOPS.No intestinal abnormality,air or fluid.

CT interpretation: Are u sure you have not had any other contrast imaging study within a few days before this CT you mentioned? If not then the CT you had must have been with contrast. Never the less, it sound like you have had a normal result with contrast appropriately moving through the small bowel and colon. Good luck I hope you feel better ...Read more

Uc flare with thin stools, chunks of blood in stool, and frequency. Egd, colonoscopy, biopsies & digital perianal & rectal exam all normal. confused?

UC is long-term: Ulcerative colitis is a lifelong inflammatory disease of the lining of the large intestine and rectum, that may have systemic consequences, is often relapsing, and can lead to colon cancer. Flares may occur acutely, even after an unremarkable colon evaluation. Don't delay in ruling out superimposed infection, & seeking help from your gastroenterologist. Call him/her now-- ...Read more

Could impacted stool in large colon and rectum cause black stools?

Could impacted stool in large colon and rectum cause black stools?

Not likely: From the standpoint of the medical profession, black stools -called melena - are always assumed to be blood. Usually representing bleeding from stomach or "higher up" within the intestines. Colon bleeding usually is red. Unfortunately, bismouth containing medications can also cause black stool, but even with that type of product, one cannot be sure there is not bleeding also. Needs evaluation. ...Read more

Barium swallow found a large, abnormally shaped mass in esophagus- & narrowing of esoph. wall but blood work normal- rules out cancer?

Not necessarily: Normal blood work does not rule out cancer. An abnormal mass in the esophagus needs to be biopsied and tissue examined by a pathologist to make a definitive diagnosis. Please follow you doctor's advice. ...Read more

Can "mild colitis' found on colonscopy biopsy cause small nodes or fat deposits in abdominal ct scan? MRCP & EUS normal. I'm worried, Blood normal.

Can "mild colitis' found on colonscopy biopsy cause small nodes or fat deposits in abdominal ct scan? MRCP & EUS normal. I'm worried, Blood normal.

Maybe lymph nodes: colitis doesn't cause fat. I can cause lymph nodes to enlarge. LN enlargement is not abnormal if there is adjacent inflammation. With all other things being OK, I would not worry. If you are, ask your doctor to do follow up scans. Try to avoid CT due to the added radiation. ...Read more

Polyp removed in upper rectum and solitary rectal ulcer sowed in flexible sigmoidoscopy. still start tip of stool is hard and red blood on stool help!

Polyp removed in upper rectum and solitary rectal ulcer sowed in flexible sigmoidoscopy. still start tip of stool is hard and red blood on stool help!

Start simple, but...: Docusate (per PDR) helps moisten & soften hard, dry stools. It is not a true laxative, but facilitates natural defecation, usually within 12 to 72 hours. This is safe &available for anyone over 2, &a assumes normal GI anatomy without inflammation, stenosis, extrinsic or instrinsic obstruction. Change in bowels is a "red flag", like weight loss or blood in stool, that needs evaluation if persistent ...Read more

Can mild thickening and fat in wall of large bowel including sigmoid colon and right colon on CT scan be normal?

Can mild thickening and fat in wall of large bowel including sigmoid colon and right colon on CT scan be normal?

Yes: While fat within the intestinal wall is often thought of as a reliable marker for inflammatory bowel disease, studies have shown that in the absence of clinical or other radiologic evidence of inflammatory bowel disease, the presence of fat in the intestinal wall may represent a normal finding. There is also thought to be some association with obesity. ...Read more

Can CT with rectal and IV contrast rule out small polyps or lessions in the colon?proctoscope and rectal exam are clean.no blood in stool.

Can CT with rectal and IV contrast rule out small polyps or lessions in the colon?proctoscope and rectal exam are clean.no blood in stool.

Small polyps: would be very difficult to diagnose on such an exam. A tailored "CT Colonography" would be better. Standard colonoscopy would be best. ...Read more

Are small sessile colon polyps usually cancerous?

Are small sessile colon polyps usually cancerous?

No ...: ... On the contrary. The smaller the polyp, the less likely it is to be "cancerous". Sessile just means flat (harder to find) versus pedunculated (mushroom-shaped). The precancerous type of polyps are adenomatous and serrated polyps (documented on pathology). Hyperplastic polyps in general are almost always benign and never turn into cancer. ...Read more

Small lesion near cecum which needs CT scan. Colonscoopy last year did not have this. Bright blood, Hemoriods found in both colonscoppies. Cancer?

Small lesion near cecum which needs CT scan. Colonscoopy last year did not have this. Bright blood, Hemoriods found in both colonscoppies. Cancer?

A consideration: Cecal lesions identified on colonoscopy really need confirmation. If something is confirmed (not always the case) it might be a benign polyp, a fecolith (solidified stool), or a small cancer. The bright red blood isn't particularly concerning for a cecal cancer as it is likely due to the diagnosed hemorrhoids. Follow your doctor's recommendations for work up with CT scan/other tests. Good luck! ...Read more

Endoscopy done, multiple sessile polyps 3-6cm in size in entire stomach. Does this require surgery? Sessile mean cancer?

Endoscopy done, multiple sessile polyps 3-6cm in size in entire stomach. Does this require surgery? Sessile mean cancer?

Do U mean mm not cm?: Multiple diminutive to small sessile polyps of the stomach, as may often be seen with prolonged use of acid suppression therapy, are typically glandular & therefore of little clinical concern. However, if your multiple polyps are 3-6 centimeters in size, then they R very concerning--please check with your diagnosing physician as to the histology of these sizable lesions & his/her recommendations. ...Read more
