Acalculous gallbladder pain: a largely unrecognised entity
1The Wakefield Clinic for Gastrointestinal Diseases, Wellington.
Aim:
To study the presentation for and outcome of cholecystectomy in patients with acalculous gallbladder pain.
Methods:
Sixty-six consecutive patients with prospective documentation underwent cholecystectomy for putative acalculous gallbladder pain between December 1988 to April 1995. The diagnosis was made on clinical grounds, but in the majority, a CCK oral cholecystogram was performed. Outcomes were assessed by postal questionnaire mailed in October 1995 or by the last recorded follow- up.
Results:
Fifty-eight females and eight males, with a median age of 37.5 years had experienced abdominal pain, usually with associated nausea, for a median of three years. Preoperative investigations were non-contributory, with the exception of the CCK oral cholecystogram which was regarded as abnormal in all instances. At a median follow-up of 40 months, 48 patients (72.7%) described their symptoms as either totally relieved or much improved by cholecystectomy.
Conclusion:
Though the pathophysiology remains poorly understood, there is clearly a group of patients who suffer from gallbladder pain in the absence of gallstones and who benefit from cholecystectomy.

Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
