• #1 Acute Appendicitis: Efficient Diagnosis and Management | AAFP

  https://www.aafp.org/pubs/afp/issues/2018/0701/p25.html

  Appendicitis is one of the most common causes of acute abdominal pain in adults and children, with a lifetime risk of 8.6% in males and 6.7% in females. […] Right lower quadrant pain, abdominal rigidity, and periumbilical pain radiating to the right lower quadrant are the best signs for ruling in acute appendicitis in adults. […] Absent or decreased bowel sounds, a positive psoas sign, a positive obturator sign, and a positive Rovsing sign are most reliable for ruling in acute appendicitis in children. […] Prolonged duration of symptoms before surgical intervention raises the risk. […] In moderate- to high-risk patients, surgical consultation should be accomplished quickly to reduce morbidity and mortality resulting from perforation. […] In a study of 375 children, risk factors for appendiceal perforation included fever, vomiting, longer duration of symptoms, elevated C-reactive protein level or white blood cell count, and ultrasound findings of free abdominal fluid, visualized perforation, or a mean appendix diameter of 11 mm or more.

  Appendicitis is acute inflammation of the vermiform appendix, typically resulting in abdominal pain, anorexia, and abdominal tenderness. The classic acute appendicitis symptoms are Epigastric or periumbilical pain followed by brief nausea, vomiting, and anorexia. After a few hours, the pain shifts to the right lower quadrant. Pain increases with cough and motion. Classic signs of appendicitis are Right lower quadrant direct and rebound tenderness located at the McBurney point (junction of the middle and outer thirds of the line joining the umbilicus to the anterior superior iliac spine). Additional appendicitis signs are pain felt in the right lower quadrant with palpation of the left lower quadrant (Rovsing sign), an increase in pain caused by passive extension of the right hip joint that stretches the iliopsoas muscle (psoas sign), or pain caused by passive internal rotation of the flexed thigh (obturator sign). Low-grade fever (rectal temperature 37.7 to 38.3 C [100 to 101 F]) is common. Many variations of appendicitis symptoms and signs occur in 50% of patients. Atypical symptoms are common among older patients and pregnant women; in particular, pain is less severe and local tenderness is less marked. Without surgery or antibiotics, the mortality rate for appendicitis is high. With early surgery, the mortality rate is 1% in high-resource areas, and convalescence is normally rapid and complete. With complications (rupture and development of an abscess or peritonitis) and/or advanced age, the prognosis is worse.
