Klatskin Tumour: Meticulous Preoperative Work-Up and Resection Rate

2011

BACKGROUND: Surgery represents the only potentially curative treatment of hilar cholangiocarcinoma (hilCC). It may be suggested that meticulous preoperative work-up in Asian countries leads to higher resection rates. METHOD: One hundred and eighty-two patients treated in our department between 1998 and 2008 were included in an analysis based on our prospectively recorded database. Among them, 75 % had a percutaneous transhepatic cholangiography as part of their diagnostic work-up. A total of 160 patients underwent explorative surgery and 123 patients were resected (77 % of patients undergoing exploration, 68 % of all patients). RESULTS: Ninety-one percent of the patients were diagnosed to h…

Non-invasive assessment of coronary artery stent patency with multislice CT: preliminary experience.

2005

To evaluate the diagnostic accuracy of multislice computed tomography coronary angiography (MSCT-CA) in the detection of in-stent restenosis.Forty-two patients (33 male, 9 female, mean age 58+/-8 years) previously subjected to percutaneous implantation of coronary stent with suspected in-stent restenosis, underwent a 16-row MSCT (Sensation 16, Siemens) examination. The average time between stent implantation and MSCT-CA was 7.4+/-5.3 months. The following scan parameters were used: collimation 16x0.75 mm, rotation time 0.42 s, feed 3.0 mm/rot., kV 120, mAs 500. After administration of iodinated contrast material (Iomeprol 400 mgI/ml, 100 ml at 4 ml/s) and bolus chaser (40 ml of saline at 4 …

Diagnosis of sclerosing cholangitis in children: blinded, comparative study of magnetic resonance versus endoscopic cholangiography.

2013

Summary Background Magnetic resonance cholangiography (MRC) has been validated as comparable to endoscopic retrograde cholangiography (ERC) for the diagnosis of sclerosing cholangitis (SC) in adult patients. In children, MRC is widely used based mainly on non-comparative studies. Patients and methods ERCs and MRCs of seven children (median age 9, range: 7–20 years) with SC and 17 controls (median age 6, range: 2 months–20 years) with other chronic liver diseases were reviewed in a blinded, random and independent way. All patients underwent both examinations within a 6-months slot. All ERCs and 17 MRCs were performed under general anesthesia. One radiologist evaluated both ERCs and MRCs and …

Radiation exposure in biliary procedures performed to manage anastomotic strictures in pediatric liver transplant recipients: comparison between radi…

2013

The aim of this study was to estimate radiation exposure in pediatric liver transplants recipients who underwent biliary interventional procedures and to compare radiation exposure levels between biliary interventional procedures performed using an image intensifier-based angiographic system (IIDS) and a flat panel detector-based interventional system (FPDS). We enrolled 34 consecutive pediatric liver transplant recipients with biliary strictures between January 2008 and March 2013 with a total of 170 image-guided procedures. The dose-area product (DAP) and fluoroscopy time was recorded for each procedure. The mean age was 61 months (range 4–192), and mean weight was 17 kg (range 4–41). The…

Intraoperative cholangiography during laparoscopic cholecystectomy: What role?

2012

Aim: Laparoscopic cholecystectomy has increased the number of iatrogenic lesion of the biliary tree. In this study, we evaluate the role of intra-operative cholangiography in prevention of biliary tree iatrogenic lesions and early identification of choledocolithiasis, during laparoscopic cholecystectomy. Material of study: 169 patients who underwent laparoscopic cholecystectomy, were evaluated by means of intra-operative cholangiography. Patients were divided into two groups basing on the risk to develop biliary tree lithiasis. Discussion: Patients with a higher risk of postoperative complications effectively showed cholangiographic anomalies, including duct stones, dilations, anatomical va…

A small-bowel segment as a total extrahepatic bile duct replacement.

1992

• The effect of a small-bowel segment as a total extrahepatic bile duct replacement, with preservation of the bile passage through the papilla of Vater, was examined in 12 pigs followed up for 420 days. No complications during or after surgery were observed in any of the animals. The laboratory parameters were within normal range during the entire observation period. No anastomotic stenosis was evident on percutaneous transhepatic cholangiography in animals examined 2, 6, or 12 months after surgery. The intrahepatic biliary tract was not dilated. There was obvious peristalsis of the grafted small-bowel toward the papilla of Vater. Autopsies showed that the grafts had healed without any sign…

Cholangitis prevention in endoscopic Klatskin tumor palliation: air cholangiography technique.

2009

INTRODUCTION: Endoscopic biliary drainage is the treatment of choice for inoperable hilar cholangiocarcinoma (so-called Klatskin tumor). Cholangitis is the main complication post-endoscopic retrograde cholangiopancreatography (ERCP) in Klatskin patients, specially when medium contrast is injected into biliary tree that could not be subsequently drained. Bacterial cholangitis is the principal cause of mortality in these patients. The aim of this study is to analyze cholangitis rate resulting from the use of air versus iodine contrast to obtain cholangiography during ERCP. METHODS: In 9 years, 188 inoperable Klatskin patients were recruited and divided into two groups: iodine (A) or air (B) c…
