13. K-ras oncogene mutations indicate malignancy in cystic tumors of the pancreas.
OBJECTIVE: To evaluate clinical parameters, presurgical diagnostic tests, histologic findings, and the presence of K-ras oncogene mutations in cystic tumors of the pancreas to determine which best predict malignancy. SUMMARY BACKGROUND DATA: Because presurgical, intraoperative, and final pathologic differentiation is difficult in cystic tumors of the pancrea

14. Useful predictors of bile duct stones in patients undergoing laparoscopic cholecystectomy. McGill Gallstone Treatment Group.
OBJECTIVE: The authors determined the most useful predictors of common bile duct (CBD) stones as diagnosed by endoscopic retrograde cholangiopancreatography (ERCP) in patients who underwent laparoscopic cholecystectomy (LC). METHODS: Prospective and retrospective collection of historical, biochemical and ultrasonographic data was used. Receiver operating cha

15. Evaluation of serial changes of pancreatic branch duct intraductal papillary mucinous neoplasms by follow-up with magnetic resonance imaging
The purpose of this study was to clarify the biological behaviour of branch duct type intraductal papillary mucinous neoplasm (IPMN) by evaluating serial changes at magnetic resonance cholangiopancreatography (MRCP). Fifty-two patients with a diagnosis of branch duct IPMN based on either endoscopic retrograde cholangiopancreatography (ERCP) (9/52) and/or MRC

16. Endoscopic management of biliary fistulas complicating liver transplantation and other hepatobiliary operations.
OBJECTIVE: This study was undertaken to prospectively evaluate the efficacy and safety of endoscopic management of biliary fistulas complicating liver transplantation and other hepatobiliary operations. SUMMARY BACKGROUND DATA: Surgical therapy has been the traditional approach to large or unresolving biliary fistulas complicating liver transplantation. Alth

17. Cholecystectomy without operative cholangiography. Implications for common bile duct injury and retained common bile duct stones.
OBJECTIVE: This study evaluated the selective use of endoscopic retrograde cholangiopancreatography (ERCP) in the context of laparoscopic cholecystectomy (LC) while minimizing the use of operative cholangiography. SUMMARY BACKGROUND DATA: There has been a long-standing debate between routine and selective operative cholangiography that has resurfaced with LC

18. Collective review of small carcinomas of the pancreas.
To determine problems involved in the treatment and diagnosis of pancreatic cancer, a collective study of small carcinoma of the pancreas (2 cm or less in diameter) was performed. One hundred six cases were collected and analyzed. The results were as follows: In small carcinoma of the pancreas, the resectability rate was 99.0% and the operative mortality rat

19. Solitary cystic dilatation of the intrahepatic bile duct.
A 31 year old man was hospitalised with general fatigue and epigastric pain. Abdominal ultrasonography, computed tomography, and magnetic resonance imaging showed a cystic lesion in the left lobe of the liver. Endoscopic retrograde cholangio-pancreatography and percutaneous trans-hepatic cholangiography revealed a localised dilatation of the intrahepatic bil

20. The spectrum of serous cystadenoma of the pancreas. Clinical, pathologic, and surgical aspects.
Serous cystadenoma of the pancreas is a rare lesion thought to be almost invariably benign. Since 1978, 211 cases have been reported in the literature. Some have been recognized by computed tomography (CT) when small and asymptomatic. The authors have reviewed their experience with 40 patients (median follow-up of 1.9 years, maximum of 22.2 years) from 1936

21. Cystic duct patency in malignant obstructive jaundice. An ERCP-based study relevant to the role of laparoscopic cholecystojejunostomy.
OBJECTIVE: This endoscopic retrograde cholangiopancreatography-(ERCP)based study estimates the potential role of laparoscopic cholecystojejunostomy for palliation of patients with malignant obstructive jaundice. SUMMARY BACKGROUND DATA: Traditional treatment of malignant obstructive jaundice has used a standard bilioenteric anastomosis. Laparoscopic biliary

22. Laparoscopic cholangiography. Results and indications.
One hundred sixty-five operative cholangiograms were attempted in 364 patients who underwent laparoscopic cholecystectomy (45%). Laparoscopic cholangiography was successful in 150 of 165 attempts (91%). Eighty-nine per cent of studies were normal (134/150) and 11% were abnormal (16/150). All 134 patients with normal cholangiograms remained asymptomatic (fals

23. Pancreatic abnormalities and AIDS related sclerosing cholangitis.
OBJECTIVES: Biliary tract abnormalities are well recognised in AIDS, most frequently related to opportunistic infection with Cryptosporidium, Microsporidium, and cytomegalovirus. We noted a high frequency of pancreatic abnormalities associated with biliary tract disease. To define these further we reviewed the clinical and radiological features in these pati

24. A prospective evaluation of cytology from biliary strictures.
BACKGROUND: Bile duct strictures may be benign or malignant. A definite diagnosis is desirable to advise patients of their prognosis and to identify any amenable to curative surgery. AIMS: To compare different methods of cytology sampling from biliary strictures and evaluate the use of cytology in this context. PATIENTS AND METHODS: In a prospective study 54
