Stent or stoma as a bridge to surgery in patients with acute malignant colorectal obstruction: a comparison of oncologic long-term results.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To evaluate the long-term oncologic results in patients treated for malignant left-sided colorectal obstruction with colonic stent or a deviating stoma as bridge to surgery. Methods: This was a single-center, retrospective cohort study comparing survival between 24 patients treated with stents for acute left-sided malignant obstruction and 32 patients who underwent a diverting stoma from 2003 to 2014. All patients subsequently underwent resection surgery with curative intent. Results: There were no significant differences between the two groups regarding age, sex, ASA classification, adjuvant chemotherapy, or tumor stage. Median time from acute treatment of obstruction to resection surgery was 30 days in the stent group and 55 days in the stoma group. There were no differences in 30-day complications between the two groups, neither for complications related to the stent or stoma intervention nor for overall complications. Stent-related perforation rate was 1/24 (4.2%). The cumulative 5-year overall survival was 63% in patients treated with a stent and 77% in patients treated with a stoma (p = 0.319). There were two cases of local recurrence in each group (p = 1.0). Conclusions: We found no differences in short-term complications or long-term oncologic outcomes between the two treatment groups. However, this may be due to a type II error, and larger studies are needed to confirm these results.
