This removal is normally performed as an emergency procedure when the patient is suffering from acute appendicitis. In the absence of surgical facilities, intravenous antibiotics are used to delay or avoid the onset of sepsis. In some cases, the appendicitis resolves completely; more often, an inflammatory mass forms around the appendix.
MRI scan is less readily available than CT scan or ultrasound in hospitals to diagnose IAIs. However, it has been proposed to be used in those who are pregnant and have inconclusive findings on ultrasound. The sensitivity and specificity of MRI in diagnosing acute appendicitis are 94% and 96% respectively. [2]
The presentation of acute appendicitis includes acute abdominal pain, nausea, vomiting, and fever. As the appendix becomes more swollen and inflamed, it begins to irritate the adjoining abdominal wall. This leads the pain to localize at the right lower quadrant. This classic migration of pain may not appear in children under three years.
It is also called appendicolith when it occurs in the appendix and is sometimes concurrent with appendicitis. [1] They can also obstruct diverticula. It can form secondary to fecal impaction. A fecaloma is a more severe form of fecal impaction, and a hardened fecaloma may be considered a giant fecalith. The term is from the Greek líthos=stone. [2]
Omental infarction is a rare cause of acute abdomen pain with reported incidence being less than 4 per 1000 cases of appendicitis. Omental infarction usually presents as right-sided abdominal pain although seldom causing left-sided abdominal pain and even epigastric pain.
This may mimic acute appendicitis or form a pelvic abscess. The left paracolic gutter is larger than the right, which together with the partial barrier provided by the phrenicocolic ligament (also known as Hensing's ligament), may explain why left subphrenic collections are more common than right subphrenic collections.
Infection of the appendix is appendicitis. When there is a buildup of bacteria, the appendix can get inflamed and swollen, and this leads to appendicitis. Pancreatitis is the inflammation of the pancreas. Acute pancreatitis is sudden inflammation of the pancreas that may be mild or life-threatening but usually subsides. Gallstones and excessive ...
Common causes of an acute abdomen include a gastrointestinal perforation, peptic ulcer disease, mesenteric ischemia, acute cholecystitis, appendicitis, diverticulitis, pancreatitis, and an abdominal hemorrhage. However, this is a non-exhaustative list and other less common causes may also lead to an acute abdomen. [2]
