A new scoring system for acute appendicitis significantly reduced negative appendicectomy rates. This diagnostic approach improved patient outcomes by accurately identifying patients needing surgery, lowering unnecessary procedures.

Area of Science:

Medical Diagnostics
Surgical Outcomes
Clinical Decision Support

Background:

Acute appendicitis diagnosis relies on clinical signs and lab results.
High negative appendicectomy rates pose a challenge in surgical practice.
Accurate diagnosis is crucial to avoid unnecessary surgical interventions.

Purpose of the Study:

To evaluate a novel scoring system for diagnosing acute appendicitis.
To reduce the negative appendicectomy rate through improved diagnostic accuracy.
To assess the efficacy of a prospective diagnostic and management protocol.

Main Methods:

A controlled, prospective study involving 58 patients diagnosed using five criteria: abdominal pain, vomiting, right lower quadrant tenderness, low-grade fever, and polymorphonuclear leucocytosis.

Appendicectomy was performed if four or five criteria were met; observation was used if three criteria were present.

A control group of 59 patients underwent appendicectomy by another surgical unit for comparison.

Main Results:

The trial group had a negative appendicectomy rate of 6.5% (3/46), significantly lower than the control group's 17% (10/59) (P < 0.05).
Appendicectomy was performed in 80% of the trial patients (46/58).
20% of patients in the trial group (12/58) did not undergo surgery.

Conclusions:

A simple scoring system effectively reduces the negative appendicectomy rate in acute appendicitis.
This diagnostic strategy enhances surgical decision-making and patient care.
The proposed criteria offer a reliable method for managing suspected appendicitis cases.
