Core Tip

Core tip: Endoscopic positioning of self-expandable metal stents (SEMSs) has an established role in the palliation of obstructing metastatic colorectal cancers (CRCs). More controversial is the management of re-obstruction due to intrastent tumor ingrowth. In our case, a patient with obstructing, metastatic, carcinomatous CRC, primary palliated with SEMS placement, experienced two different episodes of intrastent tumor in-growth. This occurred along with a long-lasting history of partial efficacy of chemotherapy, including bevacizumab. Both these episodes were successfully treated through subsequent stent-in-stent placement, with immediate symptom relief, no procedure-related complications (notwithstanding different negative prognostic factors), no need for chemotherapy discontinuation and, ultimately, a good quality of life.
