A colostomy obstruction occurs when the passage of waste through the stoma is partially or completely blocked. This is a serious condition that requires immediate attention to prevent complications like bowel perforation. Signs and Symptoms Common indicators that your colostomy may be obstructed include: Absence of output : No stool or gas passing into the bag for several hours. Abdominal pain and cramping : Often occurring in waves. Swelling : The stoma may appear larger or swollen. Nausea and vomiting : Particularly if the blockage is high in the digestive tract. Watery discharge : Sometimes a partial blockage allows only thin, liquid stool to leak around the obstruction. Common Causes Metal Stent Insertion for Malignant Obstruction of a Colostomy
Understanding Colostomy Obstruction: Causes, Symptoms, and Treatment A colostomy is a life-saving surgical procedure that creates an opening, known as a stoma, in the abdominal wall to allow fecal waste to exit the body when the lower part of the colon or rectum is compromised. While many individuals live full lives with a stoma, complications can occur, one of the most serious being a colostomy obstruction —a blockage that prevents waste from passing through the stoma. What is a Colostomy Obstruction? An obstruction occurs when the flow of stool is restricted or completely stopped within the colon leading to the stoma. This can be a partial or full blockage and requires prompt medical attention to prevent serious complications like bowel rupture. Common Causes Obstructions can arise shortly after surgery or years later. Key causes include: Metal Stent Insertion for Malignant Obstruction of a Colostomy
Write-Up: Colostomy Obstruction 1. Definition A partial or complete blockage of the bowel lumen at or near the stoma site, preventing the passage of stool and flatus through the colostomy. 2. Pathophysiology
Mechanical blockage within the stoma or proximal colon. Results in accumulation of fecal matter and gas proximal to the obstruction. Leads to abdominal distension, pain, nausea, and potential perforation or stoma necrosis if untreated. colostomy obstruction
3. Common Causes
Dietary: High-fiber foods (corn, nuts, seeds, raw vegetables, fruit skins). Adhesive/Stenosis: Scarring or narrowing at the skin or fascial level (late complication). Herniation: Parastomal hernia causing bowel kinking. Fecal Impaction: Hard, dry stool within the stoma or proximal limb. Volvulus: Twisting of the bowel around the stoma (rare). Adhesions: Internal bands proximal to the stoma.
4. Risk Factors
Poor chewing of food. Inadequate fluid intake. Parastomal hernia. Previous stomal stricture or surgery. Non-softening diet post-colostomy.
5. Clinical Presentation History
No output from colostomy for >8–12 hours (if normally active). Absent flatus (gas). Cramping abdominal pain, nausea, vomiting. Possible watery discharge (overflow diarrhea around the blockage). A colostomy obstruction occurs when the passage of
Physical Exam
Stoma: Pale, dry, swollen, or dusky appearance. No stool/gas with gentle irrigation attempt. Abdomen: Distended, tympanic to percussion, tender (may be localized or diffuse). Peristalsis: High-pitched or absent bowel sounds (early: increased, late: absent).
