Meta-Analysis on Damage Control Surgery in Patients With Non-Traumatic Abdominal Emergencies

November 12, 2024 updated by: Insel Gruppe AG, University Hospital Bern

Damage-Control Surgery in Patients With Non-traumatic Abdominal Emergencies: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis aims to investigate the effect of damage-control surgery on mortality in patients with non-traumatic abdominal emergencies. Literature search will be conducted using PubMed. Two meta-analyses will be performed comparing (1) mortality in patients with non-trauma damage control surgery vs. non-trauma conventional surgery and (2) the observed vs. expected mortality rate in patients undergoing non-trauma damage-control surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

After the successful implementation in trauma patients, damage control surgery (DCS) is being increasingly used in patients with non-traumatic abdominal emergencies, too. However, non-trauma DCS is an ongoing matter of debate as the open abdomen treatment typically performed in DCS is a non-anatomical situation and associated with potentially severe side effects. To date, DCS in patients with non-traumatic abdominal emergencies has not yet been comprehensively assessed in meta-analysis.

A systematic literature search will be conducted using the National Library of Medicine's Medline database (PubMed). The search strategy will be based on the PICOS process. Original research articles in English language addressing (1) mortality in patients undergoing non-trauma DCS vs. non-trauma conventional surgery or (2) the observed vs. expected mortality in non-trauma DCS will be included.

Two meta-analyses will be performed, comparing (1) mortality in patients undergoing non-trauma DCS vs. non-trauma conventional surgery and (2) the observed vs. expected mortality rate in patients undergoing non-trauma DCS based on outcome prediction scores. Meta-analysis will be performed using a random-effects model. The estimated effect size for mortality will be reported as risk difference with 95% confidence intervals. Sensitivity analysis will be performed by repeating the analysis in the subgroups of studies with the same study design and studies that applied the same outcome prediction score.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients undergoing surgery for non-traumatic abdominal emergencies.

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
