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…
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…
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…
Strategie des chirurgischen Vorgehens beim hilären Cholangiokarzinom
2006
Surgery is the decisive life-prolonging treatment in patients with hilar cholangiocarcinoma. Surgery is mainly based on empiric data. Since patients without surgery have only about 6 months to survive, to achieve a high resection rate is crucial for these patients. During diagnostic workup, percutaneous transhepatic cholangiography results in the most reliable assessment of longitudinal tumor growth. The extent of the tumor is frequently overestimated leading to the consequence of excluding the patients from surgery. En-bloc resection of the tumor and the adjacent liver should be the preferred surgical approach. So far, surgical radicality (right trisegmentectomy, extended lymphadenectomy a…
