ABSTRACT
BACKGROUND:
Placement of self-expanding metal stents has been increasingly adopted as a bridge to surgery in patients presenting with obstructed left-sided colorectal cancers. The optimal bridging time has yet to be widely established, hence this retrospective study aims to determine the optimal bridging time to elective surgery post endoluminal stenting. PATIENTS ANDMETHODS:
All patients who underwent colorectal stenting for large bowel obstruction in a single, tertiary hospital in Singapore between January 2003 and December 2017 were retrospectively identified. Patients' baseline demographics, tumour characteristics, stent-related complications, intra-operative details, post-operative complications and oncological outcomes were analysed.RESULTS:
Of the 53 patients who successfully underwent colonic stenting for malignant left sided obstruction, 33.96% of patients underwent surgery within two weeks of stent placement while 66.04% of patients underwent surgery after 2 weeks of stent placement. Univariate analysis between both groups did not demonstrate significant differences in postoperative complications and stoma formation. Significant differences were observed between both groups for stent complications (38.89% vs 8.57%, p = 0.022), on-table decompression (38.89% vs 2.86%, p = 0.001) and systemic recurrence (11.11% vs 40.00%, p = 0.030). Increased bridging interval to surgery (OR 13.16, CI 1.37-126.96, p = 0.026) was a significant risk factor for systemic recurrence on multivariate analysis.CONCLUSIONS:
Patients undergoing definitive surgery within 2 weeks of colonic stenting may have better oncological outcomes without compromising on postoperative outcomes. Further prospective studies are required to compare outcomes between emergency surgery and different bridging intervals.Palabras clave
