Causes and management of recurrent biliary pain after successful nonoperative gallstone treatment.
OBJECTIVE
To evaluate the frequency and causes of recurrent biliary colic after successful extracorporeal shock wave lithotripsy of gallstones.


METHODS
Follow-up of 77 patients for 2 yr (median) after complete gallstone clearance by lithotripsy and adjuvant oral litholysis. All patients with recurrent biliary colic were examined thoroughly (laboratory data, ultrasonography, gastroscopy); the examination included gallbladder motility testing. If the patients suffered from additional gastrointestinal complaints, further symptom-guided investigations (pH-metry, lactose absorption study, enteroclysis, colonic transit time, colonoscopy) were performed. Patients without documented gallstone recurrence underwent ERCP and sphincter of Oddi manometry. Cholecystectomy was advised for patients in whom gallstones recurred, and patients with sphincter of Oddi dysfunction underwent endoscopic sphincterotomy. If other gastrointestinal disorders were diagnosed, appropriate treatment was initiated.


RESULTS
Twenty-seven patients (35%) experienced biliary colic during follow-up. Gallstone recurrence was documented in 17 patients, and 16 of the patients who underwent cholecystectomy became symptom-free again (follow-up: 12 months). Gallbladder hypomotility was revealed in seven of the 17 patients with gallstone recurrence compared to none of the 10 patients without gallstone recurrence (p < 0.05). Microlithiasis was not detected in bile samples from the patients whose gallstones did not recur. Sphincter of Oddi dysfunction was found in four patients, and sphincterotomy cured all of them (follow-up: 9 months). Two of the remaining six patients had functional gastrointestinal disorders (reflux, constipation) and became asymptomatic after specific treatment.


CONCLUSIONS
Biliary colic often recurs after successful gallstone lithotripsy. Recurrent gallbladder stones are the main cause, but another cause is sphincter of Oddi dysfunction. Neither gallbladder hypomotility nor microlithiasis seems to cause biliary symptoms in patients without recurrence of gallstones.
