Abnormal intraoperative cholangiography. Treatment options and long-term follow-up.
OBJECTIVE: To determine the long-term outcome in patients with filling defects on intraoperative cholangiography. DESIGN: Case series; retrospective review. SETTING: Community teaching hospital. PATIENTS: All patients (n = 872) undergoing cholecystectomy from July 1993 through June 1995. Of 281 intraoperative cholangiograms performed, 89 had abnormal findings. Defects were classified as stone (n = 47), unsure (n = 29), and artifact (n = 13). Medical records were reviewed for immediate and long-term follow-up results. INTERVENTION: Need for common bile duct exploration (CBDE) or endoscopic retrograde cholangiopancreatography (ERCP). OUTCOME: Morbidity and interventions required 1 to 3 years after surgery. RESULTS: Of the 47 patients with suspected stones, 24 underwent successful operative bile duct clearance. One patient required irrigation. Of the 22 patients who left the operating room with unresolved stones, only 2 ERCPs were required. Of the 29 patients with unsure filling defects, operative clearance was successful in 1; irrigation achieved clearance in 4. Only 1 of the 24 patients who left the operating room with unsure filling defects required subsequent ERCP. CONCLUSIONS: Observation of common bile duct defects of 4 mm or smaller is an appropriate clinical alternative. Defects of 5 mm or larger represent a gray area, although few 5- to 8-mm stones will cause subsequent symptoms. In our experience, if stone extraction is clinically important, especially if the patient has jaundice, open CBDE is more effective than transcystic laparoscopic CBDE.
