ABSTRACT
BACKGROUND:
Self-expanding metallic stent (SEMS) and trans-anal colorectal tube (TCT) are alternative treatments to conventional emergency surgery for non-right-sided obstructive colon cancer (NROCC). However, the one with better short- and long-term outcomes remains controversial. Thus, this multicenter case-control study aimed to analyze and compare SEMS and TCT for NROCC.METHODS:
Patients with stage II/III NROCC who underwent surgery between January 2010 and December 2019 at either of the eight selected Japanese affiliate hospitals were, retrospectively, reviewed. Baseline characteristics between the SEMS and TCT groups were adjusted by propensity score (PS) matching.RESULTS:
Among 239 reviewed patients (SEMS 76, TCT 163), 180 were finally included in two well-balanced cohorts through PS SEMS group (65 patients) and TCT group (115 patients). Technical success, clinical success, morbidity, and short-term mortality were not significantly different between the two groups. SEMS placement achieved significantly higher rates for primary resection/anastomosis without stoma (SEMS 90.8% vs. TCT 77.4%, p < 0.001) and laparoscopic surgery (SEMS 64.6% vs. TCT 43.5%, p < 0.001) than TCT placement. However, 5-year overall survival (SEMS 83.7% vs. TCT 86.4%; p = 0.822) and 5-year relapse-free survival (SEMS 64.7% vs. TCT 66.4%; p = 0.854) showed no significant differences between these groups.CONCLUSIONS:
Both SEMS and TCT revealed similar long-term outcomes, but SEMS placement was better in achieving primary resection/anastomosis and laparoscopic surgery in patients with stage II/III NROCC.Key words
