When the diagnosis is relatively certain, appendicectomy is recommended through an incision at McBurney's point. Maternal morbidity following appendicectomy is low, except in patients in whom the appendix has perforated.
They include Psoas sign, Obturator sign, Rovsing's sign, rebound tenderness and palpation of McBurney's Point. According to a 2006 study of the presentation of acute appendicitis at an emergency surgical ward in Iran, the sensitivity and specificity of the Psoas sign is 23% & 50%, respectively.
In other studies carried out to prove its validity and a study based on 275 double contrast radiographies with barium enemas found that only 35% of the bases of the appendices were found in the 5 cm range of McBurney's point, while 15% were at more than 10 cm away in distance.
An abdominal exam revealed right lower quadrant tenderness at McBurney's point with no rebound or guarding and a negative Rovsing's sign.
On palpation of the abdomen 700 patients (70%) showed periumbilical tenderness, 1000 patients (100%) showed right iliac fossa tenderness, 1000 patients (100%) showed tenderness over McBurney's point, 760 patients (76%) showed rebound tenderness and 260 patients (26%) showed generalised tenderness.
Tenderness at McBurney's point & rebound tenderness are the most common signs in acute appendicitis.
