Background:
Emergency resection is common for malignant right-sided obstructive colon cancer. As there is evidence showing a potential benefit of self-expandable metal stents as a bridge to surgery, a new debate has been initiated.
Objective:
The aim of this study was to compare self-expandable metal stents with emergency resection in right-sided obstructive colon cancer.
Data Source:
A systematic search was conducted accessing Medline/PubMed, Scopus, Embase, and the Cochrane Database of Systematic Reviews.
Study Selection:
Studies reporting either emergency surgery or stent placement in right-sided obstructive colon cancer were included.
Intervention:
Stent or emergency resection in right-sided obstructive colon cancer.
Main Outcome Measures:
Morbidity rate, mortality rate, stoma rate, laparoscopic resection rate, anastomotic insufficiency rate, success rate of stent.
Results:
A total of 6343 patients from 16 publications were analyzed. The stent success rate was 0.92 (95% CI, 0.87 to 0.95) with perforation of 0.03 (95% CI, 0.01 to 0.06). Emergency resection was performed laparoscopically at a rate of 0.15 (95% CI, 0.09 to 0.24). Primary anastomosis rate in emergency resection was 0.95 (95% CI, 0.91 to 0.97) with an anastomotic insufficiency rate of 0.07 (95% CI, 0.04 to 0.11). The mortality rate after emergency resection was 0.05 (95% CI, 0.02 to 0.09). Primary anastomosis and anastomotic insufficiency rate were similar between the two groups (RR: 1.02; 95% CI, 0.95 to 1.1; p = 0.56 and RR: 0.53; 95% CI, 0.14 to 1.93; p = 0.33). The mortality rate in emergency resection was higher compared to stent (RR: 0.51, 95% CI 0.30 to 10.89, p = 0.016).
Limitation:
No randomized controlled trials are available.
Conclusion:
Stent is a safe and successful alternative to emergency resection and may increase the rate of minimally invasive surgery. Emergency resection, however, remains safe and did not result in higher rate of anastomotic insufficiency. Further high-quality comparative studies are warranted to assess long-term outcomes.
