Berger MY, et al. Is biliary pain exclusively related to gallbladder stones? A controlled prospective study. Br J Gen Pract. 2004 Aug;54(505):574-9.
To evaluate the relationship between biliary pain, other gastrointestinal symptoms and gallstones.
Neither biliary nor abdominal pain allow for discrimination between patients with and without gallbladder stones.
Patient population: 233 consecutive patients with abdominal pain aged 18 years and older who consulted any of 75 participating general practitioners Jan. 1996-Jun. 1998, and in whom the GP suspected symptomatic gallbladder stones

2. Ultrasound to diagnose gallstones – radiologist blinded to questionnaire results

Biliary pain: 45% of patients without gallstones 46% of patients w/gallstones who were NOT operated on 65% of patients w/gallstones who were operated on Upper abdominal pain: 77% of patients without gallstones 73% of patients w/gallstones who were NOT operated on 91% of patients w/gallstones who were operated on
