This is one of the most frequent questions in my outpatient clinic, and the honest answer is: it depends on several specific factors rather than on a universal rule. Truly asymptomatic gallstones in an otherwise healthy adult with a normally functioning gallbladder have a low annual rate of progression to symptomatic disease, and the majority of published evidence supports a watchful waiting approach for most such patients rather than prophylactic cholecystectomy. However, there are situations where surgery is recommended even without symptoms. A gallstone larger than three centimetres in diameter is associated with a higher long-term risk of gallbladder carcinoma and is generally an indication for cholecystectomy. A porcelain gallbladder, where the gallbladder wall is calcified, previously thought to uniformly require surgery, is now assessed more selectively, but selective calcification patterns do carry higher cancer risk. A patient who is diabetic and who develops acute cholecystitis has a higher risk of rapid progression to gangrenous gallbladder and is therefore a candidate for prophylactic cholecystectomy before a complication occurs. And any patient who lives far from a hospital or who will be undertaking prolonged travel to a location without surgical access may reasonably choose elective surgery rather than risk an emergency presentation under difficult circumstances.
At Narayana Multispeciality Hospital and RK Speciality Clinic, Mysuru, I assess each patient with incidental gallstones individually, reviewing the imaging carefully for any of the features that shift the recommendation from watchful waiting toward surgery.
