Postcholecystectomy syndrome

Postcholecystectomy syndrome (PCS) describes the presence of abdominal symptoms after surgical removal of the gallbladder (cholecystectomy).
Symptoms of postcholecystectomy syndrome may include:
* Upset stomach, nausea, and vomiting.
* Gas, bloating, and diarrhea.
* Persistent pain in the upper right abdomen.
Symptoms occur in about 5 to 40 percent of patients who undergo cholecystectomy,〔(【引用サイトリンク】title=Postcholecystectomy syndrome )〕 and can be transient, persistent or lifelong.
The pain associated with postcholecystectomy syndrome is usually ascribed to either sphincter of Oddi dysfunction or to post-surgical adhesions. A recent study shows that postcholecystectomy syndrome can be caused by biliary microlithiasis.
Approximately 50% of cases are due to biliary causes such as remaining stone, biliary injury, dysmotility, and choledococyst. The remaining 50% are due to non-biliary causes. This is because upper abdominal pain and gallstones are both common but are not always related.
Chronic diarrhea in postcholecystectomy syndrome is a type of bile acid diarrhea (type 3).〔 This can be treated with a bile acid sequestrant like cholestyramine〔 or colesevelam, which may be better tolerated.
