Postoperative Clinical Outcomes of Colonic Stent Placement as Bridge-to-surgery vs. Emergency Surgery in Left-sided Malignant Colonic Obstruction / 대한소화기암학회지

ABSTRACT

Background/Aims@#Colonic stenting as a bridge to elective surgery is an alternative for emergency surgery in patients with acute malignant colonic obstruction. However, since its benefits are uncertain, we aimed to establish whether it has better clinical outcomes. @*Methods@#The patients with acute malignant left-sided colon obstruction enrolled from January 2009 to December 2018 in National Health Insurance Service Ilsan Hospital. The patients were enrolled to undergo colonic stenting as a bridge to elective surgery or emergency surgery. The following oncological outcomes were assessed: incidence of complete remission, disease progression, local recurrence, and systemic recurrence. @*Results@#Out of 40 patients, 33 received self-expanding metallic stent (SEMS) as a bridge-tosurgery, and 7 underwent emergency surgery. More stoma was made in case of emergency surgery with statistical significance (p < 0.001). There were no significant differences in complete remission rate in curable left-sided malignant colonic obstruction between SEMS as a bridgeto-surgery and emergency surgery. Complete remission was achieved for 3 patients (42.9%) in the non-stent group and 27 patients (81.8%) in the stent group. There was no statistically significant difference in oncologic outcomes between the two groups (p = 0.069). According to multi-variate analysis, advanced TNM stage, Adjuvant chemotherapy, and SEMS bridge-tosurgery were significantly associated with disease-free survival. Disease-free survival rate differed significantly between the two groups (p = 0.024). @*Conclusions@#SEMS as a bridge-to-surgery might be an effective strategy and reduce stoma formation in acute malignant left-sided colon obstruction.
