Oncological Outcomes after Elective and Emergency Resection of Small Intestinal Neuroendocrine Tumours.
Observational study in Journal of gastrointestinal cancer, 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
purposeSmall intestinal neuroendocrine tumour (siNET) has distinct features and disease course compared to other gastrointestinal neuroendocrine tumours. While they mostly present with subtle symptoms, they also can present acutely requiring emergency surgical intervention. We assessed the impact of surgical intervention timing on oncological outcomes of siNET.
methodA retrospective observational single centre cohort study of all patients diagnosed with siNET, and received surgical intervention at a tertiary level hospital between 2008 and 2025.
resultsA total of 66 patients were diagnosed with SiNET. 22 patients were excluded due to incomplete data (9 patients) and not meeting the eligibility criteria (13 patients). Total of 44 patients met the inclusion criteria, with 30% underwent emergency resection (n = 13) and 70% underwent elective resection (n = 31). Small bowel obstruction represented the most common cause for emergency presentations (61%), while incidental radiological findings (39%) and carcinoid syndrome (35%) accounted for most elective presentations. Emergency cases were associated with the absence of pre-operative somatostatin receptor imaging, less findings of mesenteric mass (31% vs. 81%), more likelihood of post operative macroscopic residual disease (46% vs. 23%) and disease specific mortality (75% vs. 23%). However, there was no statistically significant difference between the two groups in primary and secondary oncological outcomes. There were no operative or in-hospital mortality in either group as well as no significant difference in complications rates between the groups.
conclusionsAlthough emergency surgery was associated with limited preoperative staging and higher proportion of R2 resections, no statistically significant differences in overall survival, recurrence-free survival, carcinoid symptom resolution or local complications were observed. However, these results need to be interpreted cautiously due to the small sample size of the study.
