Endoscopic therapy after laparoscopic cholecystectomy.
The role of endoscopic therapy after laparoscopic cholecystectomy (LC) was assessed in 62 patients referred for endoscopic retrograde cholangiopancreatography (ERCP). Patients were referred because of persistent biliary pain, jaundice, abnormal liver function tests, elevated serum amylase, abnormal ultrasound of the biliary system, or abnormal laparoscopic cholangiogram. Diagnostic imaging of the biliary system was abnormal in 47 of 62 (76%) cases. Sonographic abnormalities were seen in 33 of 57 (58%) patients: common bile duct (CBD) stones were present in 10 of 58 (17%); CBD >7 mm, in 22 of 58 (38%); and subhepatic fluid collection, in 10 of 58 (17%). Laparoscopic cholangiogram was done in nine cases, and CBD calculi were detected in eight. Magnetic resonance cholangiogram was abnormal in six of seven patients: CBD stones were seen in two cases; subhepatic fluid collection, in two; and clip-on CBD, in two. Endoscopic therapy was carried out in 46 of 62 (74%) patients: 40 of 47 (85%) had abnormal imaging (p = 0.0003); 29 of 33 (88%), abnormal sonography (p = 0.002); 10 of 10 (100%), CBD stones on sonography (p = 0.03); and 31 of 46 (67%), abnormal liver function tests before ERCP (p = 0.04). Twenty-five patients had a CBD stone extracted at ERCP. Bile leaks were treated successfully with papillotomy alone in 12 of 13 cases; a stent was necessary in 1 case. Endoscopic papillotomy was done in two patients with biliary pancreatitis, in one patient with recurrent idiopathic pancreatitis, and in five with suspected biliary dyskinesia. Surgery was necessary in four patients with a CBD transection. We conclude that most patients referred for ERCP after LC need endoscopic intervention. Abnormal imaging correlates best with the need for endoscopic therapy.
