Symptoms occur in about 5 to 40 percent of patients who undergo cholecystectomy, [1] and can be transient, persistent or lifelong. [2] [3] The chronic condition is diagnosed in approximately 10% of postcholecystectomy ...
A Sonographic Murphy sign is a finding when performing diagnostic medical sonography.It is different from the Murphy sign found on physical examination, but both signs are associated with cholecystitis [1] When the sonographer presses directly over the gallbladder, and the patient expresses pain, more than when the sonographer presses anywhere else, this is said to be a positive sonographic ...
Cholescintigraphy for acute cholecystitis has sensitivity of 97%, specificity of 94%. [7] Several investigators have found the sensitivity being consistently higher than 90% though specificity has varied from 73–99%, yet compared to ultrasonography , cholescintigraphy has proven to be superior.

Paraseptal emphysema, also called distal acinar emphysema, relates to emphysematous change next to a pleural surface, or to a fissure. [ 18 ] [ 26 ] The cystic spaces known as blebs or bullae that form in paraseptal emphysema typically occur in just one layer beneath the pleura.
Emphysematous cystitis is often indicated in patients who have air in the urine. [6] In some cases, emphysematous cystitis can cause thickening of the bladder wall. [ 7 ] Clinical subcutaneous emphysema is a rare complication of emphysematous cystitis that has a poor prognosis.
Low magnification micrograph of pneumatosis intestinalis in bowel wall.. Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity.The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
Abdominal ultrasound is commonly used in the setting of abdominal pain or an acute abdomen (sudden and/or severe abdominal pain syndrome in which surgical intervention might be necessary), in which it can diagnose appendicitis or cholecystitis. Ultrasound can also be used if there is suspicion of enlargement of one or more organs, such as used ...
In the developed world, 10 to 15% of adults have gallstones. [3] Of those with gallstones, biliary colic occurs in 1 to 4% each year. [3] Nearly 30% of people have further problems related to gallstones in the year following an attack. [3] About 15% of people with biliary colic eventually develop inflammation of the gallbladder if not treated. [3]
