New evidencecolorectal cancercolorectal surgery
Clinical takeawayConsider preoperative total colonoscopy after self-expandable metallic stent placement in patients with obstructive colorectal cancer to detect synchronous cancers and optimize surgical planning, acknowledging limitations of retrospective, single-center design and use of uncovered stents only.
What it foundPreoperative total colonoscopy after self-expandable metallic stent placement detected synchronous colorectal cancer in 18.6% of patients (8 of 43), altering surgical strategy, compared to standard preoperative imaging.
ContextConfirms the utility of preoperative colonoscopy in detecting synchronous cancers, a practice not yet universally adopted in this setting, but with noted limitations.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
