The possibility of peritonitis is the reason why acute appendicitis warrants rapid evaluation and treatment. People with suspected appendicitis may have to undergo a medical evacuation . Appendectomies have occasionally been performed in emergency conditions (i.e., not in a proper hospital) when a timely medical evacuation was impossible.
Appendicitis develops most commonly in the second trimester. [2] If appendicitis develops in a pregnant woman, an appendectomy is usually performed and should not harm the fetus. [16] The risk of premature delivery is about 10%. [17] The risk of fetal death in the perioperative period after an appendectomy for early acute appendicitis is 3 to 5%.
The sensitivity and specificity of MRI in diagnosing acute appendicitis are 94% and 96% respectively. [2] Laparoscopic surgery has also been used to diagnose the cause of IAIs when imaging is unhelpful. Besides, the laparoscopic surgery can also initiate treatment in the same setting. The accuracy is very high, in the range of 86 to 100%. [2]

The examiner holds the patient's ankle with one hand and knee with the other hand. The examiner internally rotates the hip by moving the patient's ankle away from the patient's body while allowing the knee to move only inward. This is flexion and internal rotation of the hip. In the clinical context, it is performed when acute appendicitis is ...
It is found in patients with localised peritonitis due to acute appendicitis. [1] It is similar to rebound tenderness, but may be easier to elicit when the patient has firm abdominal wall muscles. Abdominal pain on walking or running is an equivalent sign. [2]
[6] [7] [3] In a meta-analysis of those with acute appendicitis, early administration of opiates was found to alter treatment approach (with a slightly higher rate of appendectomy in those who received opiates) but diagnostic accuracy and surgical outcomes were unaffected by pain medication use. [8]
Acute appendicitis: Tillaux's triad: soft fluctuant swelling in umbilical region, swelling moves perpendicular to messentery, zone of resonance all around swelling: Mesenteric cyst: Rigler's triad: small bowel obstruction, a gallstone outside the gallbladder, and air in the bile ducts: Gallstone ileus: Wilkie's syndrome (SMA syndrome)
