5-year oncological outcomes in left-sided malignant colonic obstruction: stent as bridge to surgery
2023
Overview
Background
A considerable number of patients with colon cancer present with a colonic obstruction. The use of self-expanding metallic stents (SEMS) as a bridge to surgery (BTS) in potential curative patients with left-sided colonic cancer obstruction remains debatable. Therefore, this study aimed to investigate the 5-year oncological outcomes of using a SEMS as a BTS.
Methods
All patients with left-sided malignant colon obstruction who underwent curative surgery with no metastasis upon presentation between March 2009 and May 2013 were retrospectively reviewed and analyzed.
Results
A total of 45 patients were included, 28 patients underwent upfront surgery, and 17 patients had a stent as a bridge to surgery. T4 stage was statistically significantly higher in patients who had a SEMS as a BTS (35.3% vs. 10.7%)
(p-value 0.043)
. The mean duration in days of the SEMS to surgery was 13.76 (SD 10.08). TNM stage 3 was a prognostic factor toward distant metastasis (HR 5.05). When comparing patients who had upfront surgery to those who had a SEMS as a BTS, higher 5-year disease-free survival (75% vs. 72%) and 5-year overall survival (89% vs. 82%) were seen in patients who had upfront surgery. However, both were statistically insignificant.
Conclusion
Using self-expanding metallic stents as a bridge to surgery yields comparable 5-year survival and disease-free survival rates to upfront emergency surgery. The decision to use SEMS versus opting for emergency surgery should be made after careful patient selection and with the assistance of experienced endoscopists.
