The energy level and frequency of the shocks were gradually increased from lowest to highest (1-9 Kilo Jules and 1-2 Hertz). The end point

of a session was dependent on achievement of predetermined maximum number of shocks (6000), patient’s tolerance, stability of vital signs, development this website of hemobilia or satisfactory fragmentation of stones (5mm or less). Additional sessions were performed at least 24 hours apart to rule out complications. Outcome was assessed by CBD clearance. Both early and late complications were noted. Results From January 2007 to May 2014, 58 patients aged between 9 to 82 years (mean 47.76 ± 14.65) were treated by ESWL for CBD stones. Thirty one were female (53.4%). Main indications for ESWL were; large size stone (≥ 15mm) in 43 (74.1%), CBD stricture in 17 (29.3%) and

incarcerated stone in 8 (13.8%) patients. The presenting complaints include; abdominal pain in 50 (86.2%), jaundice in 40 (69%), fever in 25 (43.1%) while 18 (31%) patients were diagnosed to have cholangitis. A total of 115 ESWL sessions were performed in 58 patients with an average of 1.98 sessions per patient. The mean number of shocks was 4176 ± 1565. In 48 (82.8%) patients, the fragments were extracted endoscopically after ESWL; spontaneous passage was observed in 10 (17.2%). The CBD clearance was label as complete in 46 CDK inhibitors in clinical trials (79.3%), partial (placement of stent followed by CBD clearance at second ERCP) in 2 (3.4%) and failed in 10 (17.2%) patients. Main adverse events included fever in 7 (12.1%), cholangitis in 6 (10.3%), hematuria in 1 find more (1.7%) and hemobilia in 1 (1.7%). No procedure related death was observed. Nasobiliary drain

was displaced or removed in 6 (10.3%) cases. ESWL session could not be completed or temporarily held in 10 (17.2%) patients. Total hospital stay was 12 ± 7.26 days (range 1-42). Conclusion: The ESWL for difficult-to-retrieve CBD stones is safe and effective therapeutic option. It may be considered as an alternative to surgical exploration of CBD.

Khan, Nasir Hassan Luck, Munnawar Khaliq, Muhammad Manzoor, Zaigham Abbas Background and aim: In the last years many elastographic techniques became available for assesing the severity of the chronic liver disease and the number of liver biopsies (LB) has decreased. The aim of this paper was to compare the histology results obtained through LB with the values from the different elastographic methods ( TE, ARFI, 2D-SWE ). Material and methods: the study included patients with chronic hepatopathies B or C that underwent LB and liver stiffness (LS) measurements by three elastographic methods (TE, ARFI, 2D-SWE) in our Department, between feb. 2013 –apr. 2014. Liver histology was assessed according to the Metavir scoring.
