A Multi-State Cohort Study of Hospital Utilization and Treatment Modality for Malignant Gastrointestinal Obstructions.
Article in Journal of surgical 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
introductionMalignant obstructions are associated with morbidity, mortality, and impaired quality of life with limited population-based data on practice patterns. We characterized the association between prior cancer-related hospitalizations and receipt of operative treatment for obstruction.
methodsWe performed a retrospective cohort study of patients hospitalized with malignant gastrointestinal obstructions from colorectal, gynecologic (GYN), and hepato-pancreatico-biliary (HPB) cancers in 12 states using the Healthcare Cost and Utilization Project State Inpatient Database, 2016-2020. The primary exposure was the number of cancer-related hospitalizations in the year prior to the first hospitalization for an obstruction. Risk-adjusted use of operative treatment during the index hospitalization, enrollment in hospice, length of stay, and inpatient mortality were examined using regression.
resultsOf 8665 patients, the median age was 67 years [Interquartile Range: 58,76]. There were 3789 patients with colorectal (43.7%), 2593 patients with GYN (29.9%), and 2337 patients (26.9%) with HPB cancers. The operative rate was 24.1%. Patients with prior hospitalizations were less likely to undergo operative treatment than those who were not previously hospitalized (operative rate difference: -7.8%, p < 0.001). Operative treatment was associated with longer median length of stay ( + 8.6 days, p < 0.001), lower rates of hospice enrollment (-3.0%, p = 0.002) and lower rates of inpatient mortality (operative rate difference -2.3%, p < 0.001). The time between readmissions also decreased with each recurrent obstruction in colorectal and GYN cancers.
conclusionA greater number of previous cancer-related hospitalizations was associated with lower rates of operative treatment during the first hospitalization for a malignant obstruction. These data provide insight into the treatment trends for patients with malignant obstructions and may be helpful when counseling patients about the natural course of their disease.
