Although liver transplantation is a widely accepted treatment for hepatocellular carcinoma (HCC), much controversy remains and there is no generally accepted set of guidelines. An international consensus conference was held on Dec 2–4, 2010, in Zurich, Switzerland, with the aim of reviewing current practice regarding liver transplantation in patients with HCC and to develop internationally accepted statements and guidelines. The format of the conference was based on the Danish model. 19 working groups of experts prepared evidence-based reviews according to the Oxford classification, and drafted recommendations answering 19 specific questions. An independent jury of nine members was appointed to review these submissions and make final recommendations, after debates with the experts and audience at the conference. This report presents the final 37 statements and recommendations, covering assessment of candidates for liver transplantation, criteria for listing in cirrhotic and non-cirrhotic patients, role of tumour downstaging, management of patients on the waiting list, role of living donation, and post-transplant management.

This pooled analysis shows a marginal statistical significance in favor of adjuvant chemotherapy with an FU bolus-based regimen after complete resection of colorectal cancer metastases.

ObjectiveThis study defined negative outcomes of solid organ transplantation, proposed a new classification of complications by severity, and applied the classification to evaluate the results of orthotopic liver transplantation (OLT). Summary and Background DataThe lack of uniform reporting of negative outcomes has made reports of transplantation procedures difficult to interpret and compare. In fact, only mortality is well reported; morbidity rates and severity of complications have been poorly described. MethodsBased on previous definition and classification of complications for general surgery, a new classification for transplantation in four grades is proposed. Results including risk factors of the first 215 OLTs performed at the University of Toronto have been evaluated using the classification. ResultsAll but two patients (99%) had at least one complication of any kind, 92% of patients surviving more than 3 months had grade 1 (minor) complications, 74% had grade 2 (life-threatening) complications, and 30% had grade 3 (residual disability or cancer) complications. Twenty-nine per cent of patients had grade 4 complications (retransplantation or death). The most common grade 1 complications were steroid responsive rejection (69% of patients) and infection that did not require antibiotics or invasive procedures (23%). Grade 2 complications primarily were infection requiring antibiotics or invasive procedures (64%), postoperative bleeding requiring >3 units of packed red cells (35%), primary dysfunction (26%), and biliary disease treated with antibiotics or requiring invasive procedures (18%). The most frequent grade 3 complication was renal failure, which is defined as a permanent rise in serum creatinine levels 2 twice the pretransplantation values (1 1%). Grade 4 complications (retransplantation or death) mainly were infection (14%) and primary dysfunction (11%). Comparison between the first and last 50 OLTs of the series indicates a significant decrease in the mean number of grade 1 and 2 complications. This was partially a result of better medical status of patients at the time of transplantation. Using univariate and multivariate analyses of risk factors, the best predictor of grade 1 complications was donor 109

Hepatic resection for metastatic colorectal cancer is safe and provides good long-term overall survival rates of 47% at 5 years and 28% at 10 years. An aggressive approach is justified by the low operative mortality rate and good long-term survival, even in individuals with multiple bilobar metastases.

Since 1967, 40 patients with hydatid disease of the liver have been treated at our hospital. Diagnosis was made using clinical criteria, serology, skin tests, and imaging techniques. Thirty-five patients were operated upon. In 18 patients the cyst was uncomplicated (Group I), and in 17 the cyst was infected or communicated with the biliary tract (Group II). Three forms of surgical treatment were used: A) cyst evacuation, scolicidal irrigation, and primary cyst closure, B) evacuation, irrigation, and external drainage, and C) complete or partial cyst resection. Mebendazole was used in six patients, four of whom were also treated surgically. In Group I, one of 11 patients (8%) treated by primary closure had complications, versus four of five patients (80%) treated with external drainage (p less than 0.001). Mean postoperative hospital stay for these two groups was 11.8 versus 20.8 days, respectively (p less than 0.001). Complication rates in Group II were higher, and were evenly distributed among treatments. Patients have been followed yearly, with a median follow-up of 5 years. Active hydatid disease has been found in three patients, who all had known residual disease at initial operation. The best treatment for an uncomplicated hydatid liver cyst is evacuation, scolicidal irrigation, and primary closure. External drainage is used for infected cysts or those communicating with the biliary tract, and excision for extrahepatic and peripheral, easily resectable cysts. Mebendazole is used for intraperitoneal spillage of cyst contents and in patients with inoperable disease.
