How much Reliable Is Alvarado Scoring System in Reducing Negative Appendectomy?

Area of Science:

• Emergency Medicine
• Surgical Diagnosis
• Clinical Scoring Systems

Background:

• Accurate diagnosis of acute appendicitis remains challenging, with early detection crucial to avoid complications from delayed surgery or negative appendectomies from early intervention.
• Subtle early symptoms and clinical presentations complicate the diagnostic process for acute appendicitis.

Purpose of the Study:

• To evaluate the effectiveness of the Alvarado scoring system in reducing the rate of negative appendectomies in patients undergoing surgery for suspected acute appendicitis.

Main Methods:

• A retrospective analysis of 281 patients who underwent surgery for suspected acute appendicitis.
• Patients were categorized into negative appendectomy (Group A) and positive appendectomy (Group B) based on histological findings.
• Demographic data, Alvarado scores, and clinical parameters (WBC, left shift, rebound tenderness, pain migration) were compared between groups.

Main Results:

• A significant difference in white blood cell count, left shift, rebound tenderness, and pain migration was observed between the groups (p<0.05).
• Alvarado scores were significantly higher in patients with confirmed appendicitis (Group B) compared to those with negative appendectomies (Group A) (p<0.001).
• Logistic regression identified an Alvarado score of 7 or higher as the primary factor, with spreading pain as a secondary factor, in predicting positive appendectomies.

Conclusions:

• The Alvarado scoring system, particularly a score of 7 or above, is a valuable tool for improving diagnostic accuracy in acute appendicitis.
• Implementing the Alvarado scoring system can effectively reduce the incidence of negative appendectomies in surgical candidates.
