Objective: To compare the efficacy and safety of two types of self-expanding metallic stent (the Micro-tech type and the Boston Scientific type) as a bridge to surgery in obstructive colorectal cancer retrospectively. Methods: Data of 70 patients with obstructive colorectal cancer

in which 40 patients were in the group of Micro-tech type and 30 ones were in the group of Boston Scientific type respectively

were collected. All the patients were underwent stenting under colonoscopy from April 2015 to November 2019. The rates of complications

clinical remission

stenting success

and one-stage surgery were compared between the two groups. Results: No significant differences were found between both stents in the rates of stenting and clinical remission success. The total stenting and clinical remission success rates were 95.7% (95%vs.96.7%

P=1.000) and 94.3% (92.5%vs.96.7%

P=0.824)

respectively. The overall rate of complications was 7.14%. There was no significant difference (P=0.547) between the two groups

although a higher rate of complications was found in the group of Micro-tech type when compared with the group of Boston Scientific type (10%vs.3.33%). Regarding the one-stage surgery

the overall rate was 61.43%. The rate of one-stage surgery in Micro-tech type group was higher than the one in Boston Scientific type group (70%vs.50%)

but there was no significant difference (P=0.089). Conclusion: As a bridge to surgery

the placement of self-expanding metallic stent was safe and effective. There was no significant difference in short-term safety and efficacy between the two type of stents in our study.
