Question: Had colon cancer surgery 6 weeks ago. Had colon resection. Had about 12" of my sigmoid colon removed. T3 N0 M0 .... stage 2A .
Still having bleeding in stool after 6 weeks. I feel alright. I have a good appetite. I have gained all my weight back. I walk ever day. Feeling stronger. I do have a lot of constipation. What are possible causes for blood in the stool?
What can be done to stop the blood in my stool?

Brief Answer:
unlikely to be a cause for worry

Detailed Answer:

I do not have the details. But it is possible that intestinal staplers might be used at surgery. You also complain of constipation and that could be the cause. In that case, the circular staples usually fall off after 15-20 days and there could be bleed at that time.

This is 6 weeks since surgery. Please check for piles or fissure. If you have had a colonoscopy done prior to surgery (which most probably would be done) I do not think there is any reason for anxiety.

There need not be any anxiety for one or two episodes unless they are of large quantities. If the bleed persists after a couple of days, please get back to your doctor for evaluation.

Hello Doctor,

For my father aged 64 years, Height 6 ft, weight 80, he is having problems with the bowel movements. So we have done a Videocolonoscopy. In the last two months he has suddenly lost weight. The report is as follows :

Colonoscope passed till sigmoid colon 25cm.

Unable to pass scope beyond due to stricturing lesion.

Circumferential polypoid ulcerated lesion seen with stricturing effect.

Lession is hard to biopsy and friable on cntact.

Multiple biopsies taken

Rectum shows normal mucosa.

Retroflexed exam of rectum is normal


stricturing lesion in sigmoid colon, preventing further passage of scope..

What it could be and what should be our next steps. Please advise.

I am a 23 year old female with periodic blood in the stool on and off over the last 3-4 weeks. Four days ago, I started having heavy amounts of mucous only in a brownish-yellow color and large amounts of gas. Today, I had a white tissue-looking substance with reddish brown specks in it. In the past 6 days, I have had two bowel movements that were thinner than normal. One was accompanied by profuse sweating and abdominal discomfort.

I had colonoscopy done last year, and there were no polyps or tumours. My mother had stage 3 colon cancer in the sigmoid colon at age 35.

Should I be concerned?
