Triage and outcomes for a whole cohort of patients presenting for major emergency abdominal surgery including the No-LAP population: a prospective single-center observational study

Abstract

Purpose: This study aimed to characterize 252 consecutive patients with an indication for major emergency abdominal surgery including patients not proceeding to surgery (No-Lap). Patients who do not proceed to major emergency abdominal surgery and their clinical outcomes are not well characterized in the existing literature. Triage criteria may vary between centers, potentially impacting reported outcomes.

Methods: A single-center prospective observational study in a high-volume Danish surgical center including 252 patients presenting with an indication for major emergent abdominal surgery was conducted from the 15th of October 2020 to the 15th of August 2021. The primary outcome was to estimate the prevalence of No-Lap patients.

Results: Overall, 21 patients (8.3%) of our total study cohort did not proceed to surgery. These patients were significantly older, more comorbid with higher ASA scores, poorer performance status, and were more likely to have bowel ischemia. Poor functional performance and surgeons' consideration of futile intervention were the main reasons for deferring surgery in all 21 patients. Overall, 30-day mortality was 95% for the No-LAP cohort, 9% for the LAP cohort, and 16% for the whole cohort, respectively.

Conclusions: The No-LAP group selection process could be one of the main determinants of reported postoperative outcomes. Prospective international multi-center studies to characterize the entire cohort of patients eligible for emergency laparotomy including the No-LAP population are needed, as large variations in triage criteria and culture seem to exist. Trial registration Retrospectively registered.
