[First National Consensus on Chronic Hepatitis B].

This is the first time in our country that a group of experts in the field of hepatology gather to review the current status of HBV infection establishing the First National Consensus on Chronic Hepatitis B. With the new sensitive diagnostic methods, new antivirals capable of inhibiting viral replication, the appropriate use of passive and active immunoprophilaxis, and the better understanding of the natural history of the disease, we are finding new corners in the approach of high risk groups and management of infected patients. The National Consensus on Chronic Hepatitis B reunited 34 Mexican leaders in Hepatology, Gastroenterology, Infectology, Pediatrics, Oncology, Pathology and Molecular Biology.

Transcystic common bile duct exploration in the management of patients with choledocholithiasis.

Common bile duct stones are found in approximately 16% of patients undergoing laparoscopic cholecystectomy. If the diagnosis of choledocholithiasis is made at the preoperative workup, it is common practice to refer the patient for endoscopic retrograde cholangiography and endoscopic sphincterotomy. However, if the diagnosis is established during intraoperative cholangiography, the surgeon is confronted with a therapeutic dilemma-that is, the choice between laparoscopic common bile duct exploration, conversion to open surgery, or postoperative endoscopic sphincterotomy.
