End colostomy

• End colostomy is usually located on the left lower quadrant through the rectus muscle
• If a colostomy is being performed proximal to an obstructed lesion (thus to decompress the colon and divert the flow of stool), it is critical that the distal limb of the colon is being vented. If not there is a substantial risk of distension and subsequent perforation.
• The incidence of mucocutaneous complications seems higher when a braided suture is used compared to a monofilament suture.
• Parastomal hernia is a common complication of end colostomy, and found in over 50% of patients.
