Traditionally managed by emergency surgery, treatment decisions often involve primary resection or staged approaches, but are linked with considerable morbidity and mortality. The editorial evaluates a study by Qiu et al that proposes a nomogram benchmark for recurrence prediction, while highlighting limitations in short follow-up, tumor heterogeneity, and the need to assess model performance across multiple time horizons. It also emphasizes the growing role of self-expanding metal stents, and the importance of distinguishing residual disease from recurrence.

Traditionally, it was treated by emergency surgery, which, depending on the circumstances, could involve primary resection or staged procedures. However, this was associated with considerable morbidity and mortality. Qiu et al sought to improve this by creating a nomogram that can be used as a benchmark in the management of such patients. Although the nomogram is meant to be a predictive model for recurrence, it is only based on a snapshot of parameters at 2 years. To be of maximum benefit to patients consenting for surgery and their caregivers, the performance of the model should be assessed over both the short-and long-term intervals (e.g., 30, 60, and 90 days as well as 1, 2, and 5 years or longer) . Moreover, the heterogeneity of colorectal cancer (e.g., right-sided vs left-sided cancers vs rectal cancers) limits the nomogram’s applicability in certain situations, as it was constructed using a onesize-fits-all approach. It is also noteworthy that the increasing acceptance of selfexpanding metal stents as an option to emergency surgery provides significant benefits for patients with malignant large bowel obstruction. Lastly, it is important to distinguish residual disease from recurrence, as conflating the two may confound parameters and study endpoints. This distinction has gained renewed interest with recent advances in liquid biopsies and genomics and how they can better define minimal residual disease.  \nKey Words: Malignant large bowel obstruction; Emergency surgery; Disease recurrence; Self-expanding metal stents; Bridge-to-surgery; Right vs left colon cancer; Molecular biomarkers  \n [https://dx.doi.org/10.4240/wjgs.v18.i2.113867](https://dx.doi.org/10.4240/wjgs.v18.i2.113867) 1 February 27, 2026  Volume 18  Issue 2   \nMoyana TN.
