Background/Aims: The clinical impact of single-stage endoscopic stone extraction by endoscopic retrograde cholangiopancreatography(ERCP) and cholecystectomy during the same hospitalization remains elusive. This study aimed to determine the effcacy and safety ofsingle-stage ERCP and cholecystectomy during the same hospitalization in patients with cholangitis. Methods: We retrospectively reviewed the medical records of 166 patients who underwent ERCP for mild to moderate cholangitis dueto choledocholithiasis secondary to cholecystolithiasis from 2012 to 2016. Results: Complete stone extraction was accomplished in 92% of patients (152/166) at the first ERCP. Among 152 patients whounderwent complete stone extraction, cholecystectomy was scheduled for 119 patients (78%). Cholecystectomy was performed duringthe same hospitalization in 89% of patients (106/119). We compared two groups of patients: those who underwent cholecystectomyduring the same hospitalization (n=106) and those who underwent cholecystectomy during a subsequent hospitalization (n=13). In thedelayed group, cholecystectomy was performed about three months after the first ERCP. There were no significant differences betweenthe groups in terms of operative time, rate of postoperative complications, and interval from cholecystectomy to discharge. Conclusions: Single-stage endoscopic stone extraction is recommended in patients with mild to moderate acute cholangitis due tocholedocholithiasis. The combination of endoscopic stone extraction and cholecystectomy during the same hospitalization is safe andfeasible.

An Acoustic Survey of the Diurnal Vertical Migration of Pacific Hake off Vancouver Island , Canada
Hamano, Akira,Kieser, Robert,Cooke, Ken,McFarlane, Gordon A .,Sasakura, Toyoki 한국수산자원학회 1998 한국수산자원학회지 Vol.1 No.1
The distribution and behaviour of Pacific hake (Merluccius productus) off south-west Vancouver Island, Canada, were investigated during a joint Japan/Canada Research Cruise in the early summer of 1994. The acoustic survey was conducted along transects that crossed the shelf edge at the 200 m isobath. Quantitative echo-sounders with different frequencies (38, 50, 88, 120 and 200 ㎑) and beam patterns were used on board a Japanese and a Canadian research vessel. Substantial day night time concentrations of Pacific hake were found just beyond shelf edge. Horizontal and vertical distributions of Pacific hake were observed through echograms and volume back scattering strength (SV) measurements and by mid-water trawling. Attention was paid to the marked transitions in distribution at dusk. The following results were obtained: (1) During the daytime Pacific hake aggregations were found between 180 and 300 m depth. Substantial changes in the vertical SV profiles were observed at dusk. Distributions and changes appeared to be independent of bottom topography. (2) Following sun set Pacific hake aggregations rose closer to surface with the highest SV values between 100 and 200 m. (3) Night time distributions were light, uniform and between 100 and 300m.
