Objectives:
Stenting of malignant colon obstruction is used as a bridge to surgery or as an alternative to surgical colostomy in a palliative setting. Current guidelines recommend stent placement as the first line of treatment in colonic obstruction in both curative and palliative settings. However, it is unclear whether the location of the malignant obstruction influences the outcome of the stenting procedure. The goal of this study was to compare the outcomes of colonic stents between proximal and distal colonic strictures with regard to technical and clinical success and the risk of adverse events.
Methods:
A multi-center retrospective cohort was composed of patients who underwent a colonic stent placement at two tertiary hospitals between 2013 and 2021. The technical and clinical outcome, stent type used, duration of post-procedural hospital stay and complications were noted.
Results:
A total of 148 patients who underwent colonic stenting were identified. 41 patients underwent stent placement in the proximal colon and 107 patients underwent a distal stent placement. There was no difference in technical success (100% vs 96.3%, p = 0.209), clinical success (97.0% vs 89.6%, p = 0.199) or complications (24.4% vs 37.4%, p = 0,135).
Conclusion:
Technical success and clinical success rates are high and do not differ between stent locations. There is no significant difference in complication rates between proximal and distal colonic stents.
