Self-expanding Metallic Stents for Relieving Malignant Colorectal Obstruction

Abstract

Stenting appears to be a safe and effective addition to the armamentarium of treatment options for colorectal obstructions. However, the small sample sizes of the included studies limited the validity of the findings of this review. The results of additional comparative studies currently being undertaken will add to the certainty of the conclusions that can be drawn.

Complications of Colonoscopy

“…Other reported complications of stent placement included GI bleeding, anal pain, abdominal pain, and tenesmus which were relatively rare and generally well tolerated by patients [81]. It is not recommended to perform dilation around the time of stent placement due to increased perforation risk [76,80].…”

Management of Recurrent Large Bowel Obstruction Due to Stent Occlusion by ‘Stent-Over-Stent’: A Case Report and Literature Review

“…It is a common cause of delayed recurrent obstruction following apparently successful initial SEMS implantation, especially with the use of uncovered stents [10,21]. Prospective studies and systemic reviews showed that the time for colonic reobstruction ranged from 48 hours to 480 days after stent placement [6,13,14,21]. This variation in stent patency duration may be due to difference in demographic factors, underlying malignancies, or types of stents used [6,14].…”

In theory, uncovered owth and resultant reobstruction.…”

“…c perforation, stent migration, stent occlusion, and bleeding have been reported [1, 10,17]. In particular, stent occlusion is seen in around 10-16% of patients and occurs more frequently in palliative settings [1,6,14,20]. It is a common cause of delayed recurrent obstruction following apparently successful initial SEMS implantation, especially with the use of uncovered stents [10,21].…”

“…In palliative settings, SEMS also significantly reduce the chance of stoma creation, length of hospital stay, mortality rate, and medical complications compared with palliative surgery [1, [13][14][15]. Additionally, it allows these patients to enjoy the full benefits of minimally invasive surgery [16].…”
