# Operative and non-operative management for intestinal emergencies: findings from a single-centre retrospective cohort study

## TL;DR

This study examines patients with intestinal emergencies who received non-operative treatment and compares their outcomes with those who had surgery.

## Contribution

The study provides new insights into the outcomes of non-operative versus operative management for intestinal emergencies using electronic healthcare records.

## Key findings

- Nearly half of patients with intestinal emergencies received non-operative management.
- Non-operative patients had shorter hospital stays and fewer ICU admissions but higher 30-day mortality.
- Higher mortality was observed in non-operative patients with a higher admission National Early Warning Score.

## Abstract

Patients with an intestinal emergency who do not have surgery are poorly characterised. This study used electronic healthcare records to provide a rapid insight into the number of patients admitted with an intestinal emergency and compare short-term outcomes for non-operative and operative management.

A single-centre retrospective cohort study was conducted at a tertiary NHS hospital (from 1 December 2013 to 31 January 2020). Patients were identified using diagnosis codes for intestinal emergencies, based on the inclusion criteria for the National Emergency Laparotomy Audit. Relevant data were extracted from electronic healthcare records (n=3,997).

Nearly half of patients admitted with an intestinal emergency received nonoperative management (43.7%). Of those who underwent surgery, 63.7% were started laparoscopically. The non-operative group had a shorter hospital stay (median: 5.4 days vs 8.2 days [started laparoscopically] or 16.8 days [started open]) and fewer unintended intensive care admissions than the surgical group (2.4% vs 8.7% [started laparoscopically] 21.1% [started open]). However, 30-day mortality for non-operative treatment was double that for surgery (22.4% vs 10.1%). The 30-day mortality rate was found to be even higher for non-operative management (50.3%) compared with surgery (19.5%) in a sub-analysis of patients with admission National Early Warning Score ≥4 (n=683).

The proportion of patients with intestinal emergencies who do not have surgery is greater than expected, and it appears that many respond well to non-operative treatment. However, 30-day mortality for non-operative management was high, and the low number of admissions to intensive care suggests that major invasive treatment was not appropriate for most in this group.
