Stomas

A stoma is a surgically created opening of the bowel on the abdominal wall, through which stool is collected in a special pouch. It may be temporary or permanent. Having a stoma does not mean that an operation has failed; it is often an important protective measure that allows safer healing or treatment of a serious disease.

Ileostomy and colostomy

What it is: An ileostomy is formed from the small bowel and usually has more liquid output; a colostomy is formed from the large bowel and its output is usually more formed. Both may be end stomas or loop stomas.

Why it is created: A temporary stoma may protect a low anastomosis after rectal surgery, allow healing after a leak or severe inflammation, or manage obstruction and sepsis. A permanent stoma may be needed when the anus or the final part of the rectum has been removed, or when the bowel cannot be safely reconnected.

Living with a stoma: With education and support from the stoma nurse, most patients return to an active daily life, work, travel and exercise. After an ileostomy, adequate intake of fluids and salt is important.

Stoma complications

What they are: Early complications include ischemia, bleeding, retraction and obstruction; later, skin irritation, leakage, prolapse, stenosis, parastomal hernia or high ileostomy output may occur.

Treatment: Many are managed with specialized stoma care, a change of pouching system, dietary adjustments or a support garment. Surgical correction is needed for significant symptoms, obstruction, ischemia, recurrent leakage or inability to use the stoma safely. See also Parastomal hernia.

Stoma reversal

What it is: The operation that restores continuity of the bowel so that stool returns to its normal route. Not every stoma can be reversed.

Assessment: The reason for the stoma, healing of the anastomosis or rectum, absence of active disease or infection, sphincter function and general condition are assessed, often with CT, endoscopy or a contrast study. Timing is individualized and, when cancer is present, coordinated with oncological treatment.

After reversal: The bowel needs time to adapt. Increased stool frequency and urgency are common at first, particularly after low rectal surgery.
