Through-the-scope large diameter self-expanding metal stent placement as a safe and effective technique for palliation of malignant colorectal obstruction: A single center experience with a long-term follow-up

Abstract

In our experience, TTS large-diameter SEMS placement is a safe and effective treatment for palliation of malignant colorectal obstruction.

Palliative self-expandable metal stents for acute malignant colorectal obstruction: clinical outcomes and risk factors for complications

“…Recently, various types of stents have been introduced to prevent complications after SEMS placement. Uncovered SEMSs with a larger diameter or finer mesh can maintain luminal patency, and covered SEMSs with uncovered ends, flared ends, or inner membranes can reduce the migration rate [25][26][27]. In our study, SEMS treatment had high technical and clinical success rates as a palliative treatment.…”

Colorectal stenting as first-line treatment in acute colonic obstruction

“…In this setting, colonic stents represent the best option when skills are available [7] .

Palliative Stenting for Malignant Large Bowel Obstruction: Stents for All?

“…Interestingly, the above-mentioned study identified the length of stenosis as an independent predictor of complications. This has been previously debated in several studies with conflicting results: (1) 3 studies reported that stenting of a long obstructed segment was not associated with clinical failures [31][32][33] ; (2) however, in 2 retrospective studies, a better outcome was observed in short colon strictures [2,3] . One of these retrospective studies reported more technical failures in strictures >4 cm (OR 5.33) and even clinical failures (OR 2.40) [3] .…”
