Following are true about diverticular disease of colon EXCEPT.. Diverticulae showing irregular shape and extrinsic impression

Following are true about diverticular disease of colon EXCEPT:

• A- Thickening of the colonic wall.
• B- Dilatation of the colon… False (Narrowing).
• C- Fixation of the colon.
• D- Diverticulae showing irregular shape and extrinsic impression.

Based on the information I have access to, the only option that is not true about diverticular disease of the colon is: A. Thickening of the colonic wall.

Here's why:

Thickening of the colonic wall is a common finding in diverticular disease, especially in the sigmoid colon, which is the most commonly affected segment. This thickening is often due to fibrosis and inflammation around the diverticula.

B. Dilatation of the colon:

While some studies suggest a slight increase in colon diameter in some individuals with diverticular disease, it is not a typical or defining feature. In fact, narrowing of the colon due to strictures can occur in advanced cases of diverticulitis.

C. Fixation of the colon:

Adhesions and scar tissue formation can occur in diverticular disease, particularly after episodes of diverticulitis. This can lead to the colon becoming fixed to surrounding organs or tissues.

D. Diverticulae showing irregular shape and extrinsic impression:

Diverticula are indeed typically irregular in shape and can cause extrinsic impressions on the colon wall, appearing as pouch-like protrusions.

Therefore, option A. Thickening of the colonic wall is the only statement that is not consistently true about diverticular disease of the colon.
