This is a prospective study on 123 randomly selected patients admitted with the diagnosis of acute appendicitis. The value of rebound tenderness as a clinical diagnostic tool was statistically compared to those of some other physical signs; namely guarding, rigidity and Rovsing's sign. Rebound tenderness was found to carry the highest sensitivity (94.7%), negative predictive value (81.3%), reliability (49.1%), and association with histological diagnosis (P < 0.05). However, its specificity and positive predictive value was not significantly different from those of other physical signs. It is concluded that, in contradistinction to some previously published reports, our study emphasizes the role of rebound tenderness in the clinical diagnosis of acute appendicitis.

Rebound tenderness is generally practiced in the diagnosis of acute abdominal pain. It is a test that inflicts much discomfort to the patient. Literature data derived from reports assessing the reliability of the diagnosis of acute appendicitis indicate a sensitivity of 0.78-0.91 (pooled: 0.91) and a specificity of 0.48-0.60 (pooled: 0.60) of rebound tenderness. It would appear that rebound tenderness is a test of little specificity (leading to many false positive results) and that it has very little additional value, particularly in the presence of local tenderness and/or rigidity in patients with acute abdominal pain.

Endometriosis is prevalent among women of reproductive age, and is most commonly found in the gynecologic organs themselves and the surrounding pelvic peritoneum. Endometriosis of the appendix, however, is rare. Preoperative diagnosis is difficult and a definitive diagnosis is usually established following histopathological examination of the appendix. We report a case of endometriosis of the appendix in a 29-year-old woman who presented with right lower quadrant abdominal pain. Rebound tenderness was localized to McBurney's point. Her WBC count was 12,300/mm3 and her CRP was 6.497 mg/dl. Ultrasound and computed tomography detected a calcified region inside the cecum and slight thickening of the wall of the appendix. Based on these findings, the patient was diagnosed with acute appendicitis and underwent an appendectomy. The appendix appeared mildly congested, but the mucosa of the appendix was nearly normal and without macroscopic inflammation. Histopathological examination demonstrated ectopic endometrial glands and stroma in the muscularis. These stroma cells were positive for CD10 on immunohistochemical staining, establishing a diagnosis of endometriosis of the appendix. The patient had a good clinical course and no residual pain postoperatively.
