When two distinct stomas on proximal and distal ends are created side by side in colon, it is known as:

Appeared in: IGNOU PB Bsc Entrance-2022

Explanation

A double-barrel colostomy involves completely dividing the large intestine into two separate ends.
Both the proximal (upper) end and the distal (lower) end are brought through the abdominal wall to create two separate, distinct stomas.
The proximal stoma is the functional end that discharges feces.
The distal stoma, known as a mucus fistula, is non-functional for digestion and discharges only mucus from the resting portion of the bowel.

Option A: A loop colostomy involves bringing a loop of the colon to the surface and creating one stoma with two openings, but it is not two separate stomas.
Option B: This is a synonym for a loop colostomy and describes a single stoma, not two distinct ones.
Option C: This is not a standard or recognized medical term for a type of colostomy.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Surgical creation of different types of colostomies as background academic context rather than a clinical decision trigger.
Nurses must be able to differentiate colostomy types to provide appropriate care. In a double-barrel colostomy, care must be provided to both the functional proximal stoma and the distal mucus fistula.
Patient education is crucial. The nurse must explain the function of both stomas, reassuring the patient that mucus discharge from the distal stoma is normal.
What if? If the distal end of the bowel is surgically closed and left inside the abdomen instead of being brought to the surface, the procedure is called an end colostomy with a Hartmann's pouch.

How to Approach the Question

This is a factual recall question requiring knowledge of surgical terminology.
Focus on the key descriptors in the question stem: 'two distinct stomas' and 'side by side'.
Mentally review the definitions of the different types of colostomies provided in the options.
A 'loop' colostomy implies a single structure, which is inconsistent with 'two distinct stomas'.
The term 'double-barrel' strongly suggests two parallel structures.
Match the description of two separate stomas (one proximal, one distal) with the definition of a double-barrel colostomy.
