Abstract

fetched live from OpenAlex

Surgical management of Hinchey III and IV diverticulitis utilizes either Hartmann’s procedure (HP) or primary resection anastomosis (PRA) with or without fecal diversion. The aim of this meta-analysis is to determine which of the two procedures has a more favorable outcome. A systematic review of the existing literature was performed using the PRISMA guidelines. A meta-analysis was carried out using a Mantel-Haenszel, random effects model, and forest plots were generated. The Newcastle-Ottawa and Jadad scoring tools were used to assess the included studies. A total of 25 studies involving 3546 patients were included in this study. The overall mortality in the HP group was 10.8% across the observational studies and 9.4% in the randomized controlled trials (RCTs). The mortality rate in the PRA group was lower than that in the HP group, at 8.2% in the observational studies and 4.3% in the RCTs. A comparison of PRA vs HP demonstrated a 40% lower mortality rate in the PRA group than in the HP (OR 0.60, 95% CI 0.38–0.95, p = 0.03) when analyzing the observational studies. However, meta-analysis of the three RCTs did not demonstrate any difference in mortality, (OR 0.44 (95% CI 0.14–1.34, p = 0.15). Wound infection rates between the two groups were comparable (OR 0.75, 95% CI 0.20–2.78, p = 0.67). Analysis of observational studies suggests that PRA may be associated with a lower overall mortality. There were no differences in wound infection rates. Based on the current evidence, both surgical strategies appear to be acceptable.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
