What is a common complication associated with colorectal stent placement?

Stent obstruction is a common complication associated with colorectal stent placement due to a variety of factors. Colorectal stents are often used to relieve obstructions in the colon caused by malignant or benign conditions. Over time, stents can become obstructed due to several reasons, including the ingrowth of tissue, fecal impaction, or the stent being displaced from its original position.

The design and material of the stent can also influence the likelihood of obstruction; certain stents may be more prone to blockage if not appropriately sized or if they are positioned in a particularly challenging part of the colon. Recognizing and managing stent obstruction is crucial for maintaining bowel function and preventing further complications in patients undergoing this procedure.

Other complications of colorectal stent placement, while they can occur, are generally less common in comparison to stent obstruction. Such complications include hemorrhage and infection, which may arise but are not as directly associated with the functionality and immediate post-placement performance of the stent itself. Pneumothorax is also not relevant to this procedure, as it pertains to complications related to thoracic interventions rather than colonic stenting.
