Endoscopic retrograde brush cytology (ERBC) of the biliary and pancreatic ducts.

A new device with a brushing tube that can be introduced through the biopsy channel of the duodenoscope (Olympus JF B) used for cannulation of the papilla of Vater is reported. In 17 patients in whom ERCP had demonstrated ductal abnormalities, an endoscopic retrograde brush cytology (ERBC) was performed. A cytological diagnosis of malignancy was made in 8 patients and a possible malignancy in 2 cases. Seven cases were operated upon, and a malignant tumor was found in 6. In one case a malignant tumor was found at autopsy. Histological examination was performed in 6 cases and showed adenocarcinoma in all.. Two patients with malignant cells and ERCP-findings of suspected pancreatic carcinoma were not operated upon. The tumours were localized in 1 case to the papilla of Vater, in 2 to the biliary duct, in 4 to the pancreatic head, and in 2 cases to the pancreatic corpus. No complications occured. It is concluded that this technique provides information supplementary to that of other diagnostic procedures.

Biliary concrements: the endoscopic approach.

Since 1970, endoscopic retrograde cholangiopancreaticography (ERCP) has received much attention as a diagnostic method in pancreaticobiliary disease. The information given by ERCP is of great value in the management of patients with symptoms after biliary tract surgery and especially in patients with suspected obstructive jaundice. In patients with symptoms highly suggestive of cholelithiasis, ERCP examination should be considered for definitive diagnosis despite a negative oral cholecystogram and ultrasound finding. Endoscopic papillotomy is a major advance in the treatment of many elderly and high-risk patients with common bile duct stones. It should replace surgery in most of these patients with retained or recurrent stones and appears justified in many patients who have not yet undergone cholecystectomy, either in the hope of avoiding biliary surgery altogether or to defuse an acute clinical situation. The rule of endoscopic treatment in the young and fit has yet to be established.
