2. COMPARATIVE EVALUATION OF MAGNETIC RESONANCE CHOLANGIOPANCREATOGRAPHY AND PERIOPERATIVE CHOLANGIOGRAPHY IN PATIENTS WITH SUSPECT CHOLEDOCHOLITHIASIS
RESUMO Racional: A colelitíase é afecção de alta prevalência, sendo a coledocolitíase complicação de elevada morbidade e que necessita de métodos acurados para seu diagnóstico. Objetivo: Avaliar o perfil populacional de pacientes com suspeita de coledocolitíase e verificar o valor estatístico da colangiopancreatografia por ressonância magnéti

3. Intraoperative cholangiography during elective laparoscopic cholecystectomy: selective or routine use?
PURPOSE: To investigate clinical, laboratory and ultrasonographic parameters in patients with and without preoperative criteria for intraoperative cholangiography (IOC) during laparoscopic cholecystectomy in order to define predictive factors of choledocolithiasis. METHODS: As a criterion for inclusion in the study the patients should present chronic calculo

4. Histopathological diagnosis of intra- and extrahepatic neonatal cholestasis
The histopathology of the liver is fundamental for the differential diagnosis between intra- and extrahepatic causes of neonatal cholestasis. However, histopathological findings may overlap and there is disagreement among authors concerning those which could discriminate between intra- and extrahepatic cholestasis. Forty-six liver biopsies (35 wedge biopsies

5. "Contribuição da ressonância magnética na avaliação de doadores do lobo direito ao transplante hepático intervivos" / Contribuition of magnetic resonance in the evaluation of donors for right lobe living liver transplantation
The purpose of this study was to establish the value of the magnetic resonance in 30 potential donors for right lobe living liver transplantation. The main goal was to determine the following factors: steatosis; biliar anatomy; hepatic arterial anatomy; portal and hepatic venous anatomy, and lobar liver volume, comparing them to liver biopsy results, to intr

6. Preoperative screening for common bile duct stones with infusion cholangiography: review of 1000 patients.
OBJECTIVE: The authors aimed to study the safety and accuracy of infusion cholangiography in patients undergoing laparoscopic cholecystectomy. SUMMARY BACKGROUND DATA: Intravenous cholangiography is a theoretically attractive method of screening the common bile duct for stones. However, there still remain serious reservations regarding its safety and accurac

7. The role of endoscopic retrograde cholangiopancreatography and cholangiography in the laparoscopic era.
OBJECTIVE: The authors reviewed the results of endoscopic retrograde cholangiopancreatography (ERCP) and intraoperative cholangiography in a series of patients who underwent laparoscopic cholecystectomy. SUMMARY BACKGROUND DATA: The indications for preoperative and postoperative ERCP and intraoperative cholangiography as adjuncts to laparoscopic cholecystect

8. 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

9. Complications of cholecystectomy: risks of the laparoscopic approach and protective effects of operative cholangiography: a population-based study.
BACKGROUND: Previous studies suggest that laparoscopic cholecystectomy (LC) is associated with an increased risk of intraoperative injury involving the bile ducts, bowel, and vascular structures compared with open cholecystectomy (OC). Population-based studies are required to estimate the magnitude of the increased risk, to determine whether this is changing

10. Laparoscopic cholecystectomy and common bile duct stones. The utility of planned perioperative endoscopic retrograde cholangiography and sphincterotomy: experience with 63 patients.
OBJECTIVE: Planned perioperative endoscopic retrograde cholangiography (ERC) and sphincterotomy (ES) for suspected or proven common bile duct stones (CBDS) has been attempted in 63 of 540 consecutive patients undergoing laparoscopic cholecystectomy (LC). Experience with this intervention has been studied with respect to accuracy, efficacy, and safety. SUMMAR

11. Sampling variability of percutaneous liver biopsy in primary sclerosing cholangitis.
AIMS--To study sampling variability of percutaneous liver biopsy in primary sclerosing cholangitis (PSC). METHODS--One hundred and twelve biopsy specimens (that is, 56 pairs) from 44 patients with PSC, confirmed by cholangiography, were evaluated blindly. Six different features, qualitative grading of four other features and staging according to Ludwig were

12. Liver lesions found at colectomy in ulcerative colitis: correlation between histological findings and biochemical parameters.
AIMS--To classify lesions discovered at colectomy in patients with ulcerative colitis; to assess the importance of histological findings by correlating them with biochemical parameters. METHODS--Liver tissue specimens taken at colectomy from 59 patients with chronic ulcerative colitis were studied using light microscopy. The findings were compared with resul
