Hepatic Surgery (hepatic + surgery)
Selected AbstractsTreatment of liver metastases from neuroendocrine tumours in relation to the extent of hepatic disease,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 2 2009A. Frilling Background: Hepatic surgery is presumed to improve survival of patients with liver metastases (LM) from neuroendocrine tumours (NET). This study identified LM-specific variables that could be used as additional selection criteria for aggressive treatment. Methods: A novel classification of LM from NET was established based on their localization and presentation. Results: From 1992 to 2006, 119 patients underwent staging and treatment of LM. Three growth types of LM were identified radiologically: single metastasis (type I), isolated metastatic bulk accompanied by smaller deposits (type II) and disseminated metastatic spread (type III). The three groups differed significantly in terms of chronological presentation of LM, hormonal symptoms, Ki-67 index, 5-hydroxyindoleacetic acid and chromogranin A levels, lymph node involvement, presence of bone metastases and treatment options. The 3-, 5- and 10-year disease-specific survival rates for the entire cohort were 76·4, 63·9 and 46·5 per cent respectively. There were significant differences in survival between the three groups: 5- and 10-year rates were both 100 per cent for type I, 84 and 75 per cent respectively for type II, and 51 and 29 per cent for type III. Conclusion: The localization and biological features of LM from NET defines therapeutic management and is predictive of outcome. Copyright © 2009 British Journal of Surgery Society Ltd.

Porembka Abstract Objective:, This study aimed to evaluate if the Gyrus open forceps is a safe and efficient tool for hepatic parenchymal transection. Background:, Blood loss during hepatic transection remains a significant risk factor for morbidity and mortality associated with liver surgery. Various electrosurgical devices have been engineered to reduce blood loss. The Gyrus open forceps is a bipolar cautery device which has recently been introduced into hepatic surgery. Methods:, We conducted a single-institution, retrospective review of all liver resections performed from November 2005 through November 2007. Patients undergoing resection of at least two liver segments where the Gyrus was the primary method of transection were included. Patient charts were reviewed; clinicopathological data were collected. Results:, Of the 215 open liver resections performed during the study period, 47 patients met the inclusion criteria. Mean patient age was 61 years; 34% were female. The majority required resection for malignant disease (94%); frequent indications included colorectal metastasis (66%), hepatocellular carcinoma (6%) and cholangiocarcinoma (4%). Right hemihepatectomy (49%), left hemihepatectomy (13%) and right trisectionectomy (13%) were the most frequently performed procedures. A total of 26 patients (55%) underwent a major ancillary procedure concurrently. There were no operative mortalities. Median operative time was 220 min (range 97,398 min). Inflow occlusion was required in nine patients (19%) for a median time of 12 min (range 3,30 min). Median total estimated blood loss was 400 ml (range 10,2000 ml) and 10 patients (21%) required perioperative transfusion. All patients had macroscopically negative margins. Median length of stay was 8 days. Two patients (4%) had clinically significant bile leak. The 30-day postoperative mortality was zero. Conclusions:, Use of the Gyrus open forceps appears to be a safe and efficient manner of hepatic parenchymal transection which allows rapid transection with acceptable blood loss, a low rate of perioperative transfusion, and minimal postoperative bile leak. [source] Application of Molecular Adsorbent Recirculating System® in patients with severe liver failure after hepatic resection or transplantation: initial single-centre experiencesLIVER INTERNATIONAL, Issue 2002R Kellersmann Abstract: Acute liver failure after hepatic surgery is still plaqued with high mortality rate. Recently, a liver dialysis system (MARS®) that allows detoxification of albumin-bound substances and may hereby support liver regeneration and patient's recovery has been developed. In the present study, we report our experiences with MARS® dialysis in patients with liver failure after hepatic resection or transplantation. Between September 1999 and January 2001, five patients were treated with MARS® (2,5 courses). Though beneficial effects such as improvement of encephalopathy and renal function as well as reduced bilirubin levels were recorded during MARS® therapy, only one patient survived. Neither significant technical problems nor adverse effects occurred by using MARS® dialysis. We conclude that in surgical patients, acute liver failure is usually part of a complicated clinical course affecting multipleorgan systems. Thus, it is difficult to determine the specific influence of MARS® on patient's outcome. However, beneficial effects observed in our patients justify its continuous use and may stimulate further evaluation in controlled studies with surgical patients. [source] Effect of type of resection on outcome of hepatic resection for colorectal metastases,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 10 2007R. J. B. Finch Background: Non-anatomical liver resections have become more common in the management of colorectal liver metastases. This study examined survival and patterns of recurrence following surgery for colorectal liver metastases. Methods: Data were collected prospectively on all patients who had hepatic surgery for colorectal liver metastases at St James' University Hospital, Leeds between 1993 and May 2003, and analysed with respect to type of resection. Results: A total of 96 patients underwent non-anatomical liver resection, 280 patients had an anatomical resection, and 108 patients had a combined procedure. There was no significant difference in overall survival between the anatomical and non-anatomical groups (hazard ratio 1·14 (95 per cent confidence interval 0·60 to 2·17); P = 0·691). Intrahepatic recurrence was significantly less common in the anatomical group, whereas morbidity and mortality rates were lower in the non-anatomical group. On multivariable analysis, multiple metastases and poorer primary T stage predicted poorer overall survival and a positive resection margin predicted poorer disease-free survival. Conclusion: Non-anatomical resection can be performed with lower rates of surgical morbidity and mortality than anatomical resection, and does not disadvantage the patient in terms of overall survival.
