ABSTRACT
INTRODUCTION: The study aims to evaluate the use of "critical view of safety" (CVS) for the prevention of bile duct injuries during laparoscopic cholecystectomy for acute biliary pathology as an alternative to routine intraoperative cholangiography (IOC). METHODS: A policy of routine CVS to identify biliary anatomy and selective IOC for patients suspected to have common bile duct (CBD) stone was adopted. Receiver operator curves (ROCs) were used to identify cutoff values predicting CBD stones. RESULTS: Four hundred forty-seven consecutive, same admission laparoscopic cholecystectomies performed between August 2004 and July 2007 were reviewed. CVS was achieved in 388 (87%) patients. Where CVS was not possible, the operation was completed open. CBD stones were identified in 22/57 patients who underwent selective IOC. Preoperative liver function and CBD diameter were significantly higher in those with CBD stones (P < .001). ROC curve analysis identified preoperative cutoff values of bilirubin (35 mumol/L), alkaline phosphatase (250 IU/L), alanine aminotransferase (240 IU/L), and a CBD diameter of 10 mm, as predictive of CBD stones. No bile duct injuries occurred in this series. CONCLUSION: In acute biliary pathology, the use of CVS helps clarify the anatomy of Calot's triangle and is a suitable alternative to routine IOC. Selective cholangiography should be employed when preoperative liver function and CBD diameter are above defined thresholds.

CONTEXT: Current management of late post-pancreatectomy haemorrhage in a university hospital. OBJECTIVE: Haemorrhage after pancreaticoduodenectomy is a serious complication. We report on risk factors and outcome following management by radiological intervention. SETTING: Tertiary care centre in Scotland. SUBJECTS: Sixty-seven consecutive patients who underwent pancreaticoduodenectomy. METHODS: All pancreaticoduodenectomies over a 3-year period were reviewed. International Study Group on Pancreatic Surgery (ISGPS) definition of post-pancreatectomy haemorrhage was used. MAIN OUTCOME MEASURES: Endpoints were incidence of haemorrhage, pancreaticojejunal anastomosis leak, methicillin-resistant Staphylococcus aureus (MRSA) infection and mortality. RESULTS: Seven patients (10.4%) developed post-pancreatectomy haemorrhage out of 67 pancreaticoduodenectomies. Median age was 71 years. All post-pancreatectomy haemorrhage were late onset (median 23 days; range: 3-35 days), extraluminal and ISGPS grade C. Post-pancreatectomy haemorrhage arose from hepatic artery (n=4), superior mesenteric artery (n=1), jejunal artery (n=1), and splenic artery (n=1). Angiographic treatment was successful in all patients by embolisation (n=5) or stent grafting (n=2). Pancreatic fistula rate was similar in post-pancreatectomy haemorrhage and "no-haemorrhage" groups (57.1% vs. 40.0%; P=0.440); MRSA infection was significantly higher in post-pancreatectomy haemorrhage group (57.1% vs. 16.7%; P=0.030). Mortality from post-pancreatectomy haemorrhage despite successful haemostasis was 42.9%. Univariate and multivariate analysis identified MRSA infection as a risk factor for post-pancreatectomy haemorrhage. CONCLUSION: CT angiogram followed by conventional catheter angiography is effective for treatment of late extraluminal post-pancreatectomy haemorrhage. MRSA infection in the abdominal drain fluid increases its risk and therefore aggressive treatment of MRSA and high index of suspicion are indicated.
