Oncologic safety of stent as bridge to surgery compared to emergency radical surgery for left-sided colorectal cancer obstruction

Abstract

For left-sided colorectal cancer obstruction, stent insertion followed by surgery showed short-term advantages and similar oncologic outcomes compared to surgery without preoperative intervention. Stent insertion as a bridge to surgery is a safe and feasible treatment option for patients with colorectal cancer obstruction.

Bridge-to-surgery stent placement versus emergency surgery for acute malignant colonic obstruction

“…The authors acknowledge that the present study was limited by the retrospective non-randomized design, small numbers and difference in baseline tumour stage between groups. Still, these outcomes are in line with the results of a recent oriental study 15 . French 14 and South Korean 12 studies, however, showed worse 5-year overall survival with SEMS insertion.…”

Comparison of early and late surgery following colonic stenting for obstructive colorectal cancer

“…Oncologic outcomes between elective surgery following colonic stenting and emergency surgery are controversial. Some studies reported comparable oncologic outcomes of elective surgery after colonic stenting to emergency surgery [12][13][14]. In contrast to our findings, worse oncologic outcomes of colonic stenting were published [15,16].…”

Oncological outcome of malignant colonic obstruction in the Dutch Stent-In 2 trial

“…The group from St Vincent's University Hospital in Dublin showed similar overall and cancer‐specific survival in 49 patients. This has been echoed by others, but there have also been reports of a negative impact on cancer outcomes. One retrospective study used a propensity score to adjust for allocation bias in 48 patients who received a bridging stent and 39 who underwent emergency surgery.…”
