Use of Self-Expandable Prosthesis for the Treatment of Colon and Rectal Benign Stenosis. Systematic Review
The main reason for the use of self-expandable prosthesis (SEP) is for the treatment of malignant colonic obstructions. The objective of this study is to determine the understanding with regard to results of applying SEP in benign stenosis of colon and rectum, measured in terms of numbers, etiology, and results. Systematic review. A search on MEDLINE, Cochrane Library CENTRAL, DARE, HTA, NHSEED, EMBASE and CINAHL and TRIP database was conducted. We considered all studies published since 1990 for this report. Search strategies were applied to each database using MesH terms, truncated, free words and Booleans. The results and level of evidence of the studies were summarized in tables summarizing efficacy, safety and complications. We obtained 19 related articles. All of these were case series and case reports (evidence level 4), totaling less than 150 cases treated with SEP. The observed results were adequate in terms of symptom reduction, however, a considerable percentage of complications were observed (intestinal perforation, migration, re-obstruction and pain). Published experience concerning the results of the installation of SEP in benign strictures of colon and rectum is scarce and evidence is limited. Therefore, further studies and articles with improved methodological qualities are required.
