The safety and efficacy of ω-3 fatty acid in patients with obstructive jaundice is not known. This study provided evidences that ω-3 fatty acid-based parenteral nutrition improved postoperative recovery for patients with obstructive jaundice.
Roux-en-Y hepaticojejunostomy is the standard procedure used by most hepatobiliary surgeons for biliary reconstruction following iatrogenic bile duct injury, benign and malignant CBD strictures, choledochal cysts and biliary tract tumors management. The incidence of anastomotic stricture following hepaticojejunostomy in experienced centers ranges between 5%-22%. Hepaticojejunostomy stricture is a serious complication of biliary surgery, if untreated, can lead to repeated cholangitis, intrahepatic stones formation, biliary cirrhosis, hepatic failure and eventually death. Revision of hepaticojejunostomy is a complex procedure, the surgical procedure being made difficult by the sequelae of long-standing unrelieved biliary obstruction like portal hypertension due to secondary biliary cirrhosis, atrophy of liver lobes and presence of cholangiolytic liver abscess. Endoscopic management is not only the least invasive but also very effective via either balloon dilatation or stenting of the stricture. In patients with "Roux-en-Y" hepaticojejunostomy, the endoscopic access to the anastomosis is hampered by the distance traveled by the jejunal loop until reaching the angle of the enteral anastomosis. Many modifications of hepaticojejunostomy to provide permanent endoscopic access have been described in the literature including duodenal, gastric and subcutaneous access loops. Gastric access loop was first described by Sitaram et al. Ten patients had undergone gastric access loop. Access loop was entered easily with the gastroscope in five patients in whom it was attempted. In a series with 16 cases, Hamad MA and El-Amin H assessed different construction of gastric access loop in the form of bilioenterogastrostomy the overall success rate of endoscopic access to the HJ through the three types of BEG was 87.5%, while it was 100% for BEG type III, which is a construction similar to the previous series (BEG) type. Subcutaneous loop access was described by Chen et al. and by Huston et al. In Hutson's series of 7 patients, recurrent strictures were treated with repeated balloon dilations. The stone extractions were all successful. In most series, the subcutaneous loop was used for management os HJ stricture and intrahepatic stones by radiologic intervention. Recently the subcutaneous loop can be used as an endoscopic biliary access.
Primary Objective: To document state-of- the-art multi-modality management of occluded biliary SEMS aiming to minimize number of reinterventions while providing symptom relief without procedure-related serious adverse events. NOTE: This study will be hypothesis-generating for an anticipated randomized controlled study (RCT) to compare outcomes of placement of a plastic stent inside the occluded SEMS to outcomes of the proposed multi-modality approach.
This study evaluates corticosteroids in the treatment of obstructive jaundice in autoimmune pancreatitis and/or immunoglobulin G4 (IgG4)-related sclerosing cholangitis in adults. Half of participants will receive corticosteroids alone, while the other half will receive corticosteroids with biliary stent at the beginning.
Parenteral nutrition (PN) provides intravenous nutritional supplementation for infants unable to absorb adequate enteral nutrients secondary to insufficient intestinal length or function. In early PN-associated cholestasis, the dose of traditional soy based lipid is limited to 1 g/kg/day which often limits the growth capacity of parenteral nutrition-dependent infants. Inadequate growth is directly related to poor neurological outcomes, failure to facilitate mechanical ventilation, and less growth of the neonate's already damaged intestine. Ultimately, these outcomes can lead to severe disability and death. To mitigate these deleterious effects and optimize growth, parenteral nutrition-dependent infants with cholestasis who are not adequately growing on 1 g/kg/day of soy-based lipid emulsion must have a greater intake of lipids to meet their needs for weight, length, and head circumference growth. SMOFlipid contains a mixture of 4 different lipid sources: soybean oil which provides essential fatty acids, olive oil which is high in monounsaturated fatty acids that are less susceptible to lipid peroxidation than polyunsaturated fatty acids, medium-chain triglycerides which show a faster metabolic clearance than long-chain triglycerides, and fish oil which provides the supply of omega-3 fatty acids. The utility of Omegaven and soy-based lipid emulsion is limited as these are restricted to 1 g/kg/day in cholestatic infants. SMOFlipid is safe to be provided at the usual goal infusion amount of 3 g/kg/day. Because this product includes both omega-6 and omega-3 lipids, it provides the benefits of the omega-3s for the liver and provides more than enough omega-6s to meet essential fatty acid requirements. Its use in situations in which growth is inadequate in babies who must be restricted to 1 g/kg/day can be expected to improve their growth and likely markedly increase their chances of both a good neurological outcome and survival. The aim of this research study is to determine if the unique formulation of SMOFLipid will cause less hepatic inflammation compared to soy only intralipids.
Endoscopic sphincterotomy is now an established method for removal of common bile duct calculi and treatment of papillary stenosis, the sump syndrome and certain cases of ampullary carcinoma. It is also generally performed prior to biliary stent placement .Anatomical variations, papillary stenosis, impacted stones, ampullary tumors, duodenal diverticula, and post-gastrojejunostomy states are some of the reasons behind difficult common bile duct (CBD) cannulations . In these situations, the success of CBD cannulation can be enhanced slightly by using the various accessories designed for this purpose.The aim of this study is to prospectively compare conventional approach and needle knife fistulotomy in cannulation of ampulla of Vater during endoscopic retrograde cholangiopancreatography regarding procedure-related complications as failure of cannulations, bleeding and perforation and postoperative complication
This phase-2 study aims to evaluate feasibility, safety and efficacy of thermal ablation of biliary obstructive malignancies by means of radiofrequency ablation (RFA, ELRA, StarMed) during endoscopic retrograde cholangio-pancreaticography (ERCP) with primary intent to obtain palliative biliary drainage via stenting
RATIONALE:Anticholinesterase drugs and cholinergic M receptor antagonist are applied to patients who have obstructive jaundice after operation. PURPOSE:This clinical trial was designed to lower the incidence and mortality of operation complications in patients with obstructive jaundice .
Patients with obstructive jaundice due to periampullary tumor can temporarily be relieved of their jaundice with transpapillary stenting at endoscopic retrograde cholangio-pancreatography (ERCP) prior to operation. Usually plastic stents are used. Hypothesis: Self expanding metallic stents offer a be a better alternative for preoperative stenting in patients with obstructive jaundice due to periampullary tumour obstruction.
