What are the symptoms of appendicitis?

Introduction

Appendicitis is a common medical condition characterized by inflammation of the appendix. It typically presents with a variety of symptoms that can vary in intensity and location, making diagnosis sometimes challenging. Understanding the common and atypical symptoms is crucial for timely and accurate diagnosis to prevent complications such as perforation.

Key Insights

Abdominal Pain and Tenderness:
- Abdominal pain, particularly starting in the epigastric or periumbilical region and migrating to the right lower quadrant, is a predominant symptom .
- Right lower quadrant tenderness is a significant physical examination finding .
Gastrointestinal Symptoms:
- Anorexia, nausea, and vomiting are common symptoms associated with appendicitis .
- Diarrhea and dysuria can occur, especially in cases with atypical presentations.
Fever and Inflammatory Signs:
- Fever is often present and can be a helpful diagnostic sign .
- Muscle rigidity and rebound tenderness in the abdominal wall are indicative of peritonitis, a complication of appendicitis .
Atypical Presentations:
- Atypical symptoms, such as pain in unusual locations (e.g., right upper quadrant), can occur due to variable appendix positions or in specific populations like pregnant women and the elderly.
- Pediatric patients may present with nonspecific symptoms like irritability and hip pain, while elderly patients often present later with more generalized pain and peritoneal signs.
Diagnostic Challenges:
- The presence of a positive psoas sign and migratory pain to the right lower quadrant increases the likelihood of appendicitis, while vomiting before pain makes it less likely.
- The Shchetkin-Blumberg symptom (rebound tenderness) is not specific to appendicitis but indicates peritoneal inflammation.

Conclusion

Appendicitis typically presents with abdominal pain that migrates to the right lower quadrant, accompanied by gastrointestinal symptoms such as anorexia, nausea, and vomiting. Fever and abdominal tenderness are also common. However, atypical presentations can occur, especially in specific populations like pregnant women, children, and the elderly, making diagnosis more challenging. Recognizing these symptoms and their variations is essential for timely and accurate diagnosis to prevent complications.

Appendicitis is a common condition with abdominal pain and anorexia as the predominant symptoms, and early diagnosis is crucial to reduce complications and mortality rates.

US diagnosis of acute appendicitis

Acute appendicitis is diagnosed by evaluating anorexia, nausea, vomiting, and pain, with a sensitivity of 80% and specificity of 80% in the right lower quadrant.

Does this patient have appendicitis?

History and physical examination are as accurate as laboratory methods in diagnosing or excluding appendicitis, with key signs and symptoms including a positive psoas sign, fever, and migratory pain to the right lower quadrant.

THE NATURE OF THE SYMPTOMS IN APPENDICITIS

Appendicitis symptoms arise from increased energy passing through sympathetic nerves, affecting neighboring nerve cells and causing symptoms based on their function.

[Significance of the separate symptoms in acute appendicitis].

Acute appendicitis' most informative symptoms are pain in the right inguinal region, muscle rigidity, and a Volkovich-Kocher symptom, while Shchetkin-Blumberg and Rovzing symptoms are of limited value.

What Patients Will Have an “Atypical” Presentation for Appendicitis? What Are Those Presentations?

Atypical presentations of appendicitis include pregnancy, atypical anatomy, and elderly patients, as well as those with perforation more frequently than the general population.

DIAGNOSIS AND SYMPTOMS OF APPENDICITIS.

The pain is generally sharp and acute, but in the chronic fulminating type, when the appendix is ruptured and diffuse, the pain is dull and constant.

Appendicitis with symptoms in left lower quadrant.

Acute symptoms involving the left lower quadrant of the abdomen are often misdiagnosed as a variety of other conditions, such as gastrointestinal bleeding, septic shock, and inflammatory bowel disease.

Diagnosis of acute appendicitis.

Advances in imaginology have improved the diagnosis of acute appendicitis, but despite these advances, the diagnosis remains a challenge due to atypical presentations and varying clinical symptoms.

Appendicitis

Appendicitis is a common abdominal surgical emergency, with a lifetime risk of 9% for males and 7% for females, and 80% of cases occurring before 45 years of age.
