Abstract

fetched live from OpenAlex

AIM: The timing of ileostomy reversal has been the subject of controversy, with researchers investigating the safety of early versus late stoma closure. Anecdotally, a longer duration of faecal diversion is associated with a greater incidence of postoperative ileus. We sought to investigate the association between duration of diversion and postoperative ileus. METHOD: We conducted an institutional retrospective cohort study on 173 patients undergoing ileostomy closure between 2012 and 2018. Our primary outcome was ileus; secondary outcomes included postoperative complications and descriptive factors. We investigated the association between duration of diversion and ileus using several analyses to ensure that time was treated appropriately as a continuous, nonlinear variable. RESULTS: In all, 20.2% of patients had an ileus. Multivariate analysis did not identify a significant association between any independent predictors and ileus, although there was a trend towards increased risk of ileus with increasing duration of diversion. When treated as a categorical variable, a duration of diversion >328 days independently increased the odds of ileus (OR = 3.25, P = 0.033). Duration of diversion was associated with days to first flatus and to first diet (P = 0.025 and P = 0.004, respectively). When patients received nasogastric intubation, the mean duration of intubation was 3.2 days. CONCLUSION: Greater duration of diversion was associated with a trend towards increased risk of ileus; this risk tripled when diversion lasted more than 328 days.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
