Delayed surgical intervention is

associated with elevated morbidity and mortality rates, increased likelihood of ICU admission, and prolonged post-operative hospitalization [175–179]. Ascending cholangitis AZD4547 cell line Ascending cholangitis is a life-threatening condition that must be treated in a timely manner. Early treatment, which includes appropriate antibiotic coverage, hydratation, and biliary decompression, is of utmost importance in the management of acute cholangitis (Recommendation 1A). The appropriatness of biliary drainage in patients with acute cholangitis depends on specific clinical findings, and this procedure may be secondary to a previous failed treatment. Cholangitis varies greatly www.selleckchem.com/products/Trichostatin-A.html in severity, ranging from a mild form requiring parenteral antibiotics to severe or suppurative cholangitis, which requires early drainage of the biliary tree to prevent further complications [180]. Retrospective studies have shown that, 20–30 years ago, when biliary drainage was not available, the mortality rate of conservatively treated acute cholangitis was extremely high [181]. Given that emergency biliary drainage in patients with acute cholangitis is not always necessary or feasible, it is very

important that surgeons promptly and effectively triage patients, distinguishing those who require this urgent procedure from those who do not. In 2001, Hui et al. [182] published a prospective study investigating predictive criteria for emergency biliary decompression for 142 patients with acute cholangitis. Emergency ERCP was associated with fever, a maximum heart rate exceeding 100 beats per minute, albumin less than 30 g/L, bilirubin greater than 50 μmol/L, and prothrombin time exceeding 14 seconds. There are 3 common methods used to perform biliary drainage: endoscopic drainage, percutaneous 3-Methyladenine transhepatic drainage, and open drainage. Endoscopic drainage of the biliary tree is safer and

more effective than open drainage (Recommendation A). Endoscopic biliary drainage is a well-established means of biliary decompression for patients with acute cholangitis caused by malignant or benign biliary disease and associated biliary obstruction [183, 184]. Amino acid Many retrospective case-series studies have also demonstrated the efficacy of percutaneous transhepatic drainage. Endoscopic modalities of biliary drainage are currently favored over percutaneous procedures due to reduced complication rates. There are currently no RCTs comparing endoscopic and percutaneous drainage. (Recommendation 2C). Currently, only retrospective studies have been published comparing the safety and effectiveness of endoscopic and percutaneous transhepatic biliary drainage in the treatment of acute obstructive suppurative cholangitis. These reports confirmed the clinical efficacy of endoscopic drainage as well as its ability to facilitate subsequent endoscopic or surgical intervention [185].
