OBJECTIVES: The aim of this article is to describe best practices for performing percutaneous transhepatic cholangiography with placement of a biliary drain (PTCD), percutaneous transhepatic removal of bile duct stones, percutaneous stenting of the bile ducts, and percutaneous treatment of postoperative bilioma. MATERIALS AND METHODS: The authors reviewed existing literature on relevant current recommendations and presented them based on their own facility's approach...

Endoscopic retrograde cholangiopancreatography (ERCP) is the technique of choice for the treatment of biliopancreatic pathology. However, fluoroscopic imaging does not always allow an adequate diagnosis. On the other hand, some large stones cannot be removed by the usual methods. In these situations, cholangioscopy has proven to be an essential tool for the diagnosis of biliary strictures and the treatment of large stones. Its role in pancreatic pathology is also increasing. The development of a single-operator, disposable cholangioscope has made it possible to expand the technique to a large number of hospitals that perform ERCP...

Gallstone ileus is an intestinal obstruction that is secondary to the presence of gallstones in the small intestine. It is a rare complication of cholelithiasis, which represents 1-3% of the causes of intestinal obstruction. The diagnosis is difficult given that the symptoms are nonspecific with intermittent intestinal obstruction, Rigler's triad (pneumobilia, stone and abdominal distention) is pathognomonic. Among the diagnostic aids are abdominal radiography, ultrasound and abdominal tomography. Treatment should be individualized depending on the patient's conditions, with laparotomy with enterotomy being the treatment of choice...

INTRODUCTION: Bile duct stones constitutes 20% of symptomatic gallbladder disease and difficult stones are one third of this. Endoscopic papillary large balloon dilation (EPLBD) with or without prior endoscopic sphincterotomy (EST) produces excellent outcomes for the treatment of complex or difficult common bile duct (CBD) stones, alone or combined with previous therapeutic options as mechanical lithotripsy (ML) and temporary or definitive stenting. OBJECTIVES: Show success rate, complications and adverse events...

BACKGROUND AND STUDY AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for the treatment of biliary obstruction of any etiology. However, cannulation failure of the common bile duct (CBD) by ERCP occurs in 5-10%. Alternatives after a failed ERCP are re-ERCP by an expert endoscopist, percutaneous transhepatic cholangio drainage (PTCD), (balloon) enteroscopy-assisted ERCP, or surgery. Endoscopic ultrasonography-guided drainage of the bile ducts (EUS-BD) is becoming the standard of care in tertiary referral centers for cases of failed ERCP in patients with malignant obstruction of the CBD...

Posponer cirugías electivas durante el proceso pandémico de Covid-19 aumentó el riesgo de complicaciones graves de enfermedades benignas. El íleo biliar es una de las raras complicaciones de la colelitiasis (0,3-0,5%). Los episodios recurrentes de colecistitis aguda están involucrados en la fisiopatología. La demostración de la tríada de Rigler en tomografía computarizada es diagnóstica. Para reducir la morbilidad se recomienda la cirugía dos etapas: extirpar el cálculo por enterotomía en la primera operación, cirugía biliar en la segunda operación...

Patients with viral hepatitis have disturbances of biliary tract motor function with the tendency to hypertonus of Oddi's sphincter, changes of physic-colloid properties of bile with increase in density of gall and hepatic bile, pH shift to acid side, microlites formation, disorders in biochemical composition of bile. More than 80% patients have biliar insufficiency. According to our data, with the purpose to correct of disturbances of hepatic exocrine function in patients with viral hepatitis and to prevent stone formation, it is reasonable to use together with antiviral therapy also intravenous injection of ozonated physiological solution and preparations of ursodeoxycholic acid...

OBJECTIVE: This study intended to evaluate predictive factors for cholelithiasis in morbidly obese submitted to gastroplasty with "Y" de Roux reconstruction. METHODS: The population under study was a group of obese patients enrolled in a program of surgical procedure for morbid obesity at the Department of Surgery, College of Medical Sciences, Santa Casa de São Paulo. The exclusion criteria were: patients previously cholecystectomized, patients with diagnosis of pre-operative cholelithiasis and patients with a questionable ultrasonography about existence of billiary stones...

Obesity increases significantly the risk of developing several common gastrointestinal diseases such as gallstone disease (GD) and hepatic steatosis (HS). Elsewhere we have shown a relationship between HDL cholesterol, cholesterol saturation index, and leptin in obese patients loosing weight. Furthermore, leptin plays an important role facilitating HS and possibly in the associated inflammatory process. The aim of this study was to investigate the relationship between GD and HS. The sample was comprised by patients attending the unit for check-up...

BACKGROUND: Endoscopic biliary stenting is often used for large or difficult common bile duct (CBD) stones, but the effect of indwelling endoprosthesis on size or fragmentation of stones after long-term treatment with biliary stenting has not been formally established. We compared the stone size or fragmentation of common bile duct stones after a long period of biliary stenting. METHODS: Endoscopic biliary endoprosthesis was performed for 49 high-risk patients with CBD stones too large or difficult to be extracted by conventional endoscopic means...

INTRODUCTION: Common bile duct calculi represent a pathologic entity involving obstructive icterus, cholangitis, hepatic cirrhosis or pancreatitits. Common bile duct calculi mostly have a secondary origin (from gallbladder) in 95% of cases, while primary choledocholithiasis is rare. CLASSIFICATION: From surgical aspect, common bile duct calculi can be: 1. Asymptomatic, without manifested symptoms or signs, 2. Mobile, with intermittent biliar obstruction and disobstruction, 3...

Biliar calculi from 32 patients with juxtapapillary duodenal diverticula were analyzed by quantitative infrared spectroscopy. In 22 of the patients the calculi were classified as pigment stones and in 10 as cholesterol stones. Calcium bilirubinate was the main component in the pigment stones, with a median value of 45%; the median cholesterol content was 7.5%. In the cholesterol stones median calcium bilirubinate content was 1% and median cholesterol content 95.5%. Calcium carbonate was found in small amounts in only nine of the calculi...

Congenital cystic segmentary dilatation of the intrahepatic biliary ducts is a rare disease. Although several cases has been described in medical literature, its occurrence such as it was originally referred is exceptional. Some cases coexist with congenital hepatic fibrosis and portal hypertension. A characteristic phenomenon is the formation of stones and canalicular infection. In this article, three cases of Caroli disease (females, 57, 53 and 58 years old) are described. Case n 1 was a complex malformation including: a) cystic and segmentary dilatations of the intrahepatic biliar ducts; b) intra and extrahepatic lithiasis and recurrent infections; c) fusion of the choledocus and gallbladder in a common sac; d) hepatic cavernosus hemangioma and a supernumerarious lobe...
