Background: Acute appendicitis is one of the most common causes of acute abdomen requiring emergency surgery. Early diagnosis is crucial to prevent perforation and complications.

Aim: To study the clinical presentation, laboratory findings, imaging features, and outcomes of patients diagnosed with acute appendicitis.

Methods: A prospective observational study was conducted on 100 patients admitted with acute appendicitis. Data on symptoms, clinical signs, laboratory investigations (WBC count, CRP), ultrasonography findings, treatment methods, and postoperative complications were collected and analyzed.

Results: The most common symptom was abdominal pain (100%), followed by nausea/vomiting (65%) and fever (40%). Raised WBC count (>11,000/mm³) was seen in 78% of cases. Ultrasound confirmed appendicitis in 85% of cases. Laparoscopic appendectomy was performed in 72% of patients, while open surgery was done in 28%. Postoperative complications occurred in 12% cases, mostly wound infection.

Conclusion: Pain in the right lower abdomen with elevated WBC and USG findings are key diagnostic tools. Early diagnosis and laparoscopic surgery lead to better outcomes.
