A temporary self-expanding metallic stent for malignant colorectal obstruction

Abstract

Temporary SEMS is a safe and effective approach in patients with malignant colorectal obstruction due to low complication rates and good medium-term outcomes.

Safety and Efficacy of Percutaneous Cecostomy/Colostomy for Treatment of Large Bowel Obstruction in Adults with Cancer

“…Endoscopic interventions are widely acknowledged as alternatives to surgery for colonic obstruction. A number of recent studies have established endoscopic stent placement as a valid primary or "bridging" therapy in the setting of malignant bowel obstruction (22)(23)(24)(25)(26). However, as evident in the present study, many patients with cancer are not appropriate candidates for endoscopic stent placement, and some who appear to be may not show any improvement after endoscopic intervention.…”

Advanced Colonoscopy

“…In Xiao-Li et al [ 38 ], the mean and median periods of relief of obstructive symptoms were 97.25 ± 9.56 days (95 % CI: 79, 116) and 105 ± 17.43 days (95 % CI: 70, 139), respectively. In Larssen et al [ 39 ], SEMS were used in palliation of multiple malignant gastrointestinal (GI) obstructions, and the patency for colonic stents was 276 days.…”

“…Most late stent-induced complications such as reobstruction and migration can be remedied with further stenting. The colorectal stent design is an evolving process leading to radial force that is evenly spread with smooth edges [ 38 ].…”

Definition of large bowel obstruction by primary colorectal cancer: A systematic review

“…The definitions of these 42 studies are displayed in Table 2, thereby separating the used terms and descriptions for each of the five predefined elements. The definition was solely based on clinical symptoms in 11 studies [5][6][7][8][9][10][11][12][13][14][15] or solely on radiological imaging in six studies [16][17][18][19][20][21] (Figure 2). In the remaining studies, a combination of clinical symptoms with or without duration, physical examination, endoscopic features or radiological imaging was incorporated into the definition of obstruction.…”
