Abstract
INTRODUCTION The aim of this study was to establish the value of alpha-foetoprotein (AFP) for the screening of recurrences in hepatocellular carcinoma (HCC) in patients who have undergone curative hepatic resection. METHODS 72 HCC patients who had curative resection/liver transplant in 2000-2006 were monitored for recurrence by evaluating the three- or six-monthly AFP and computed tomography images. Patients without recurrence were followed up for a mean duration of 7.27 years. RESULTS Out of the 72 patients, 34 (47.2%) suffered from HCC recurrence. 65.4% of recurrent cases had AFP values showing an upward trend. Patients with recurrence had higher AFP values than those without at last follow-up (119.45 μg/L vs. 3.1 μg/L, p < 0.001). AFP at recurrence was independent of gender, race, history of alcohol consumption and hepatitis C or cirrhosis status. Patient with hepatitis B or those with tumours larger than 5 cm had higher AFP values. The best cut-off AFP indicative of HCC recurrence was 5.45 μg/L (sensitivity 84.4%; specificity 77.1%). High preoperative AFP was associated with high AFP at recurrence (correlation coefficient 0.553, p = 0.01). CONCLUSION AFP alone is an inadequate screening test for HCC recurrence since only about two-thirds of patients showed upward AFP trend on recurrence. Our study found a relatively low cut-off point for detection of recurrence (5.54 μg/L). Patients with high preoperative AFP tended to have high AFP on recurrence. Imaging is recommended for patients with AFP levels > 5.45 μg/L, especially when AFP shows a rising trend.

Abstract
Chronic portal vein thrombosis (PVT) is often considered a relative contraindication for living donor liver transplantation due to the risks involved and higher morbidity. In this report, we describe a surgical strategy for living donor liver transplant in patient with complete PVT using venovenous bypass from the inferior mesenteric vein (IMV) and then using a jump graft from the IMV for portal inflow into the graft. IMV is a potential source for portal inflow in orthotopic liver transplant.

Abstract
BACKGROUND Biliary injury during cholecystectomy can be managed successfully by biliary reconstruction in the majority of patients; however, a proportion of patients may require hepatic resection or even liver transplantation. METHODS Data on all patients referred with biliary injuries were recorded prospectively. The details of patients who required hepatic resection or transplantation were analyzed and compared to those patients managed with biliary reconstruction alone. RESULTS From November 1984 until November 2003 there were 119 patients referred with Strasberg grade E injuries to the biliary tree, 14 of whom (9 women, 5 men) required hepatic resection or transplantation. The median age of these 14 patients was 48 (range: 30-81) years. Nine patients were considered for hepatic resection, and of these six underwent right hepatectomy, two had a left lateral sectionectomy, and one patient was deemed unfit for surgery and underwent metal stenting of the right hepatic duct. All patients are alive and remain well. Five patients developed hepatic failure and were considered for liver transplantation. Two patients who were unfit for transplantation died, and another died while on the waiting list for transplantation. The remaining two patients underwent liver transplantation, and one of them died from overwhelming sepsis. Concomitant vascular injury was demonstrated in 8 of the 14 patients (57%), and in 3 of the 4 (75%) patients that died. CONCLUSIONS Hepatic atrophy or sepsis after biliary injury can be managed successfully with hepatic resection. Liver transplantation is required occasionally for patients with secondary biliary cirrhosis, but is rarely successful for early hepatic failure following iatrogenic biliary injury.

Abstract
BACKGROUND Magnetic resonance cholangiopancreatography (MRCP) is an emerging modality in the management of acute gallstone pancreatitis (AGP). The aim of this study was to assess the impact following the introduction of MRCP in the management of AGP in a tertiary referral unit. METHODS Patients presenting with AGP from January 2002 to December 2004 were reviewed to assess the impact of the introduction of MRCP in June 2003. The indication for MRCP was suspected common bile duct (CBD) stones in the absence of biliary sepsis. Definitive treatment for AGP was laparoscopic cholecystectomy, with endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy reserved for patients unfit for cholecystectomy and those with biliary sepsis. RESULTS 249 patients were identified of whom 36 (14.5%) underwent ERCP and sphincterotomy as definitive treatment. 96 patients with a non-dilated CBD and normal or resolving liver function tests proceeded to laparosocopic cholecystectomy and intraoperative cholangiogram (IOC), 8 (8.5%) of whom had CBD stones intraoperatively. Eleven patients underwent cholecystectomy during pancreatic necrosectomy. Of those undergoing preoperative diagnostic biliary tract imaging, ERCP was undertaken in 57 patients and MRCP in 49 patients. There was no significant difference in serum bilirubin levels [ERCP 43 mmol/l (18-204) vs. MRCP 39 mmol/l (24-180), p = NS] or the proportion of patients with CBD stones [ERCP 10 (17.5%) vs. MRCP 7 (14.2%), p = NS] between the two groups. Patients who underwent MRCP had a shorter median hospital stay [MRCP 5 days (range: 3-14) vs. ERCP 9 days (range: 4-20), p < 0.01] and higher rate of cholecystectomy during the index admission (MRCP 83.3% vs. ERCP 67.2%, p < 0.05). There was a high degree of correlation between preoperative MRCP results and findings of subsequent IOC or therapeutic ERCP (area under ROC curve: 0.94). CONCLUSIONS MRCP is an accurate modality for imaging the axial biliary tree in patients with AGP. Selective use of MRCP reduces the need for ERCP and results in shorter hospital stay. and IAP.

Abstract
Pancreatic necrosectomy remains an important treatment modality for the management of infected pancreatic necrosis but is associated with significant mortality. The aim of this study was to identify factors associated with mortality following pancreatic necrosectomy. Patients who underwent pancreatic necrosectomy from January 1995 to December 2004 were reviewed. The association between admission, preoperative and postoperative variables, and mortality was assessed using logistic regression analysis. A total of 1248 patients presented with acute pancreatitis, of whom 94 (7.5%) underwent pancreatic necrosectomy (51 men, 43 women). The preoperative median Acute Physiology, Age, and Chronic Health Evaluation (APACHE II) score was 9 (range 2-19). The median cumulative organ dysfunction score was 2 (0-9) preoperatively and 4 (1-11) postoperatively. In all, 23 patients (24.5%) died. Those who died were older than the survivors; the ages (median and range) were 69 years (40-80 years) versus 52 years (19-79 years) (p < 0.05). They also had higher admission APACHE II scores (median and range): 14 (12-19) versus 9 (2-22) (p < 0.001). There were significant associations between preoperative (p < 0.01) and postoperative (p < 0.01) Marshall scores and mortality following pancreatic necrosectomy. The presence of the systemic inflammatory response syndrome (SIRS) during the first 48 hours (p < 0.01) and the time between presentation and necrosectomy (p < 0.01) were independent predictors of survival. Pancreatic necrosectomy is associated with higher mortality in patients with increased APACHE II scores, early persistent SIRS, and unresolved multiorgan dysfunction. Necrosectomy is associated with poorer outcome when performed within 2 weeks of presentation.

Abstract
BACKGROUND The aim of this study was to audit the management of patients with acute pancreatitis against the standards of practice in the British Society of Gastroenterology guidelines. METHODS The study assessed consecutive patients with acute pancreatitis over 5 years. Audit targets were overall mortality below 10 per cent, mortality for severe acute pancreatitis below 30 per cent, correct diagnosis and severity stratification within 48 h, aetiology determined in more than 80 per cent, availability of computed tomography and high-dependency or intensive therapy units when indicated and definitive treatment of gallstone pancreatitis within 2 weeks. RESULTS Of 759 patients with acute pancreatitis, 219 (28.9 per cent) had severe acute pancreatitis (SAP). Overall mortality was 5.9 per cent, and 19.6 per cent in those with SAP. Acute pancreatitis was diagnosed within 48 h of presentation in 96.3 per cent of patients. The definitive aetiology was classified in 87.5 per cent. Of patients with SAP, 95.9 per cent underwent computed tomography within 6-10 days of admission. Of 93 patients with severe gallstone pancreatitis, 48 per cent had urgent endoscopic retrograde cholangiopancreatography, and 89.6 per cent of 359 patients with acute gallstone pancreatitis underwent definitive management within 2 weeks of admission. CONCLUSION Patients with acute pancreatitis can be managed according to revised guidelines with a low associated mortality.

Abstract
AIM The aim of this study was to evaluate the outcome of different techniques of palliation for patients with hilar cholangiocarcinoma. METHOD All patients treated with palliative intent between 1988 and 2004 at the Royal Infirmary of Edinburgh were reviewed. Patients were analysed on an intention to treat basis. Demographics, procedure and outcome (including re-admissions) were recorded. RESULTS Two hundred and thirty-three patients underwent palliative treatment for suspected hilar cholangiocarcinoma. The diagnosis was confirmed histologically in 109 patients. The procedure related morbidity and mortality was 54/225 and 18/207 respectively. Seventy-one patients required re-admission. Twenty patients underwent surgical biliary bypass for jaundice. Those undergoing surgical palliation had a longer median (95% CI) time to re-admission (16 (0-36) vs.7 (2-12) weeks, p=0.001). Endoscopic retrograde cholangio-pancreatography (ERCP) and stenting was only successful in 28 patients and was associated with a significantly higher re-admission rate compared to patients in whom ERCP was not performed (60/179 vs. 4/27, p=0.050). The overall median (95% CI) survival was 145 (124-185) days. CONCLUSION Current options for palliation of hilar cholangiocarcinoma provide good short term success but are all associated with significant early and late morbidity. Due to its low success and association with an increased re-admission rate, ERCP for definitive palliation should not be used in the first line staging and management of these patients.

Abstract
BACKGROUND AND AIMS Hepatocellular carcinoma (HCC) is a cancer of rising incidence in the UK. The aim of this study was to compare the Okuda, Cancer of the Liver Italian Program (CLIP), and Barcelona Clinic Liver Cancer (BCLC) classifications as predictors of survival in UK patients with HCC. METHODS Data were analysed from a prospective database maintained in a specialist hepatobiliary unit from 1998 to 2003. Each system was assessed for its discriminatory power, monotonicity of gradient, and independent contribution to prediction of mortality status based on a multivariate model. RESULTS One hundred and two patients (77 males, 25 females) were identified with a median age of 65 (range, 14-87) years. The overall median survival time was 13 months and the one- and five-year survival rates were 52.9% (95% CI: 43.2%, 62.6%) and 35.3% (95% CI: 26.0%, 44.6%), respectively. All three classification systems had the capacity to differentiate between patient survival times across different stages. The Okuda system was superior in overall discriminatory power and in strength of monotonicity. The BCLC system, however, made the highest independent contribution of all three systems in predicting survival in the Cox regression model. CONCLUSIONS All three classification systems were effective in predicting survival for patients with HCC in a UK population.

Abstract
AIM The aim of this study was to assess the value of a defined follow-up protocol for patients undergoing potentially curative hepatic resection for colorectal hepatic metastases. METHODS A standard protocol for the duration of the study consisted of clinical assessment, serum carcinoembryonic antigen (CEA) and computed tomography. Patterns of recurrence, method and timing of diagnosis and outcome were recorded. RESULTS One hundred and ninety-one patients underwent potentially curative resection from 1989 to 2004 of whom 103 developed recurrence. The median (inter-quartile range) follow-up was 24.4 (6.5-42.3) months. The median (IQR) time to recurrence and overall survival was 25.0 (10 -not yet reached) and 45.2 (21-123) months, respectively. Seventeen patients (8.9%) underwent further surgery with curative intent. Fifty-five patients (57.9%) had recurrence diagnosed at routine follow-up with 71% (44/62) being diagnosed by CEA and CT. The CEA was elevated in 85.7% (72/84 patients) at the time of diagnosis of recurrence. CONCLUSION Although the detection of recurrent disease is common during follow-up after hepatic resection for colorectal metastases, few patients will be suitable for further intervention with curative intent. The exact nature of the follow-up protocol remains to be determined but if it is going to be performed it should be most intensive within the first 3 years.

Abstract
BACKGROUND AND AIMS Pancreaticoduodenectomy (PD) is a major operative intervention performed most commonly for malignancy in the head of pancreas. The aim of this study was to evaluate the utilization of blood transfusion for PD and to determine whether this had prognostic significance in a subset of patients with pancreatic ductal adenocarcinoma (PDAC). MATERIAL AND METHODS Data on blood transfusion requirement were retrospectively collected for patients undergoing PD from 1998 to 2005. Standard prognostic factors and survival data were also collected in patients with PDAC. RESULTS One-hundred-and-seventy patients underwent PD. Seventy-six patients (45%) received transfusion. The median (interquartile range) number of units of red cell concentrate (RCC) transfused perioperatively (intraoperatively and within 24 h of surgery) was 1.5 (0.5-2.5). The median preoperative haemoglobin (Hb) was 126 g/dl. The median number of units of RCC transfused perioperatively in patients with Hb <126 g/dl was 2 (1-3); for those with Hb > or = 126 g/dl the median was 0 (0-1); p=0.003. Forty-nine patients who were resected for PDAC were subjected to survival analysis. Univariate and multivariate analyses showed that only posterior resection margin invasion was associated with an adverse outcome (margin positive 198 [143-470] days vs margin negative 398 [303-859] days; p=0.02). Perioperative RCC transfusion requirement was not a significant predictor of survival (transfusion 408 [214-769] days vs no transfusion 331 [217-391] days; p=0.18). Furthermore, RCC transfusion within 30 days of operation was not a significant predictor of poor survival (transfusion 331 [201-459] days vs no transfusion 317 [196-769] days; p=0.43). CONCLUSIONS PD can be performed with a moderately low requirement for RCC transfusion; however, low preoperative haemoglobin is a predictor for the requirement of RCC transfusion. Administration of RCC transfusion does not appear to be a significant adverse prognostic factor in patients with resected PDAC.

Abstract
BACKGROUND Mortality in patients with acute pancreatitis is associated with the number of failing organs and the severity and reversibility of organ dysfunction. The aim of this study was to assess the significance of early systemic inflammatory response syndrome (SIRS) in the development of multiorgan dysfunction syndrome (MODS) and death from acute pancreatitis. METHODS Data for all patients with a diagnosis of acute pancreatitis between January 2000 and December 2004 were reviewed. Serum C-reactive protein (CRP), Acute Physiology And Chronic Health Evaluation (APACHE) II scores and presence of SIRS were recorded on admission and at 48 h. Marshall organ dysfunction scores were calculated during the first week of presentation. Presence of SIRS and raised serum CRP levels on admission and at 48 h were correlated with the cumulative organ dysfunction scores in the first week. RESULTS A total of 759 patients with acute pancreatitis were identified, of whom 45 (5.9 per cent) died during the index admission. SIRS was identified in 162 patients on admission and was persistent in 138 at 48 h. The median (range) cumulative Marshall score in patients with persistent SIRS was significantly higher than that in patients in whom SIRS resolved and in those with no SIRS (4 (0-12), 3 (0-7) and 0 (0-9) respectively; P < 0.001). Thirty-five patients (25.4 per cent) with persistent SIRS died from acute pancreatitis, compared with six patients (8 per cent) with transient SIRS and four (0.7 per cent) without SIRS (P < 0.001). No correlation was observed between CRP level on admission and Marshall score (P = 0.810); however, there was a close correlation between CRP level at 48 h and Marshall score (P < 0.001). CONCLUSION Persistent SIRS is associated with MODS and death in patients with acute pancreatitis and is an early indicator of the likely severity of acute pancreatitis.

Abstract
Laparoscopy and laparoscopic ultrasound have been validated previously as staging tools for pancreatic cancer. The aim of this study was to identify if assessment of vascular involvement with abdominal computed tomography (CT) would allow refinement of the selection criteria for laparoscopy and laparoscopic ultrasound (LUS). The details of patients staged with LUS and abdominal CT were obtained from the unit's pancreatic cancer database. A CT grade (O, A-F) of vascular involvement was recorded by a single radiologist. Of 152 patients, who underwent a LUS, 56 (37%) had unresectable disease. Three of 26 (12%) patients with CT grade O, 27 of 88 (31%) patients with CT grade A to D, 17 of 29 (59%) patients with CT grade E and all nine patients with CT grade F were found to have unresectable disease. In all, 24% of patients with tumours <3 cm were found to have unresectable disease. In those patients with tumours considered unresectable, local vascular involvement was found in 56% of patients and vascular involvement with metastatic disease in 17%, while 20% of patients had liver metastases alone and 5% had isolated peritoneal metastases. The remaining patient was deemed unfit for resection. Selective use of laparoscopic ultrasound is indicated in the staging of periampullary tumours with CT grades A to D.

Abstract
BACKGROUND Considerable debate surrounds the timing of repair of injury to the common bile duct following cholecystectomy. In the absence of sepsis or significant peritoneal soiling, repair within the first week may be optimal. This study compared the outcome of early (within the first 2 weeks) and delayed (between 2 weeks and 6 months) repair. METHODS Data on all patients referred with biliary injuries were recorded prospectively. In the absence of sepsis or significant peritoneal soiling, repair was considered within 2 weeks. RESULTS Between November 1988 and November 2003, 123 patients were referred with injury to the biliary tree. Repair of the injury had been attempted in 55 patients (44.7 per cent) before referral. Of the 68 patients with no previous repair, nine were managed without surgery and 59 required subsequent surgical reconstruction of the ductal injury. Within the first 2 weeks after injury, 22 patients underwent primary biliary repair and three had revision of a failed biliary repair. Between 2 weeks and 6 months, a further 22 injuries were repaired. Successful repair was possible in 22 of 25 early repairs compared with 20 of 22 delayed repairs (P = 0.615). The overall operative mortality rate for patients undergoing repair was 4 per cent (two of 47 patients). CONCLUSION A successful outcome was achieved in a high proportion of patients (42 of 47) when repair of the bile duct injury was undertaken in a unit experienced in the management of biliary injury. In selected patients, early repair within the first 2 weeks resulted in a similar outcome to that of delayed repair.

Abstract
BACKGROUND Confirming the presence of hepatic or proximal bile duct malignancy pre-operatively remains difficult and some patients may undergo surgical resection for suspected malignant lesions which subsequently turn out to be benign. The aim of this study was to establish whether improvements in pre-operative staging might better identify this patient population. METHODS Analysis of a prospectively collected database, which has been maintained in our unit since 1988. RESULTS Of 250 consecutive patients undergoing hepatic resection for presumed malignancy, 18 (7.2%) were shown to have benign pathology. These "false positive" rates were 4 out of 160 (2.5%) resections for colorectal metastases, 4 out of 49 (8.2%) resections for other solid hepatobiliary tumours and 10 out of 41 (24.4%) resections for hilar cholangiocarcinoma. Four of the 18 patients (22%) developed post-operative complications but there was no postoperative mortality. CONCLUSION Although hepatic resection remains a potentially curative procedure for patients with tumours involving the liver parenchyma or proximal bile ducts, pre-operative confirmation of malignancy remains difficult. Despite appropriate investigation a subset of patients with benign disease will still be subjected to major hepatic resection which should be undertaken in a specialist unit.

Abstract
The majority of patients who present with hilar cholangiocarcinoma will have incurable disease and require only palliation. Efficient relief of disabling symptoms is required with minimal morbidity and mortality and can be achieved by either surgical or non-operative options. A review of the indications, anatomical considerations and surgical techniques is presented. Segment III cholangio-jejunostomy is the most frequently used surgical bypass procedure and in those patients with an expected survival of more than 6 months, surgical palliation offers good quality and long-lasting palliation. There is a need for randomized controlled data to define the optimal role of surgical palliation in this difficult disease.

Abstract
BACKGROUND Ampullary tumours are relatively rare, and few large single-centre reports provide information on their treatment and outcome. The aim of this study was to analyse outcome and determine predictors of survival for patients with ampullary tumours treated in a specialist centre. METHODS Over an 11-year period, 561 patients were treated for periampullary tumours, 88 of whom had a histologically proven ampullary neoplasm. Prospectively gathered data were analysed to assess predictors of survival. RESULTS The overall resection rate was 92 per cent; there were no postoperative deaths. Median survival was 45.8 months for patients with resectable tumours and 8.0 months for those with irresectable disease (P < 0.001). On univariate analysis, age less than 70 years (P = 0.015) and a bilirubin level of 75 micromol/l or less (P = 0.012) favoured long-term survival. Among 70 patients who underwent cancer resection, factors associated with significantly worse long-term survival on univariate analysis included poorly differentiated tumour (P < 0.001), positive nodes (P < 0.001), perineural invasion (P = 0.001) and invasion of the pancreas (P = 0.018). Multivariate analysis identified positive nodes and bilirubin concentration as independent predictors of survival. CONCLUSION An aggressive surgical approach to ampullary tumours is justified by the low proportion of benign lesions, the absence of postoperative mortality and improved long-term survival.

Abstract
BACKGROUND The acceptable indications for liver resection in patients with colorectal metastases have increased significantly in the last decade. It is thus becoming more difficult to ascertain the limitations for selection as the boundaries have been greatly extended. This has resulted in not only more extensive resections, but more atypical and bilobar resections. The aim of this study was to compare the outcome of patients undergoing different extent of liver resection in a specialist unit. METHODS All patients undergoing liver resection for colorectal metastases at the Royal Infirmary of Edinburgh between October 1988 and April 2001 were reviewed. Patients were allocated into one of three groups: standard group, extended group, and segmental group. Patient information was collected from a prospectively completed database. RESULTS One hundred and thirty-seven patients had liver resections for colorectal metastases during the study period. There were 69 standard hepatectomies, 41 extended resections and 27 segmental resections. CEA level was significantly lower in the segmental group(p = 0.012). There was a significant difference between the groups in terms of median operating time (p < 0.0001, Kruskal-Wallis test), operative blood loss (p = 0.006, Kruskal-Wallis test) and post-operative stay ( p = 0.036, Kruskal-Wallis test). Major post-operative complications were similar between standard and extended resections but less following segmental resection (p = 0.050. Predicted median survival was 51 months following standard resection, 23 months following extended resection and 59 months after segmental resection ( p = 0.037, log rank test), however, there was no difference between the three groups for actual 5-year survival (p = 0.662, Pearson chi-square test). CONCLUSION Morbidity and mortality rates were comparable with other previous studies as was overall survival, although survival in patients undergoing extended resections was reduced. There was an acceptable level of morbidity and mortality for all three groups. Patients undergoing segmental resection had fewer complications, shorter length of stay, and the longest median survival suggesting adequate oncological clearance. Segmental resection has a role for favourably placed tumour deposits if oncological clearance can be ensured. Extended liver resections have a role for selected patients with bilobar colorectal metastases or large solitary deposits close to the hepatic vein confluence.

Abstract
BACKGROUND Hepatic resection is indicated for a variety of benign conditions because of persistent symptoms, uncertainty regarding the diagnosis or the risk of malignant transformation. The aim of this study was to assess the indications for and outcome of hepatic resection for benign non-cystic liver lesions in a specialist hepatobiliary unit. PATIENTS AND METHODS All patients who had undergone hepatic resection for benign non-cystic hepatic lesions between 1989 and 2001 were identified from a prospective database for analysis. RESULTS A total of 49 patients (40 women, 9 men) with a mean age of 43 years (range 21-75 years) underwent resection of non-cystic benign lesions. Indications for operation included suspected liver cell adenoma (n=11), suspicion of malignancy (11), persistent symptoms attributable to the lesion (20) or chronic sepsis (7). The final diagnosis was focal nodular hyperplasia (n=12), haemangioma (12), adenoma (8), sclerosing cholangitis (5), inflammatory pseudotumour (4), intrahepatic cholelithiasis (3), chronic hepatic abscess (3), benign biliary fibrosis (I) and leiomyoma (I). Major anatomical hepatic resections were performed in 44 patients, and 5 patients underwent a segmentectomy or minor atypical resection. Median operating time was 215 min (range 45-450 min) and median blood loss was 875 ml (range 200-4000 ml). Ten patients (20%) required a median blood transfusion of 2 units (range 2-8 units). The median postoperative stay was 10 days (range 4-33 days). There were no deaths, but complications occurred in 15 patients (27%). CONCLUSIONS Hepatic resection can be safely recommended for selected patients with a variety of benign non-cystic hepatic lesions. A small group of patients undergo resection as a result of inability to rule out a malignant process, but the large majority will be operated on because of either their malignant potential or related symptoms.

Abstract
Transarterial chemoembolisation of liver tumours is typically followed by elevated body temperature and liver transaminase enzymes. This has often been considered to indicate successful embolisation. The present study questions whether this syndrome reflects damage to tumour cells or to the normal hepatic tissue. The responses to 256 embolisations undertaken in 145 patients subdivided into those with hepatocyte-derived (primary hepatocellular carcinoma) and nonhepatocyte-derived tumours (secondary metastases) were analysed to assess the relative effects of tumour necrosis and damage to normal hepatocytes in each group. Cytolysis, measured by elevated alanine aminotransferase, was detected in 85% of patients, and there was no difference in the abnormalities in liver function tests measured between the two groups. Furthermore, cytolysis was associated with a higher rate of postprocedure symptoms and side effects, and elevated temperature was associated with a worse survival on univariate analysis. Multivariate analysis demonstrated that there was no benefit in terms of survival from having elevated temperature or cytolysis following embolisation. Cytolysis after chemoembolisation is probably due to damage to normal hepatocytes. Temperature changes may reflect tumour necrosis or necrosis of the healthy tissue. There is no evidence that either a postchemoembolisation fever or cytolysis is associated with an enhanced tumour response or improved long-term survival in patients with primary or secondary liver cancer.

Abstract
BACKGROUND The aim of this retrospective study was to review all patients diagnosed with gallbladder cancer over a 10-year period to assess variables affecting survival. METHODS Patients diagnosed with gallbladder cancer from January 1990 to December 1999 were identified from the Lothian Surgical Audit database and a case-note review was performed. RESULTS The 44 patients who were studied (33 women, 11 men) had a mean age of 66 years (range 42-90 years). The diagnosis was established preoperatively in 25 patients (57%), intraoperatively in 5 patients (11%) and incidentally following pathological examination of cholecystectomy specimens in 14 patients (32%). None of the 25 patients diagnosed preoperatively underwent curative operations (median survival 4 months). All five patients diagnosed at the time of attempted cholecystectomy had advanced irresectable disease (median survival 1 month). The overall median survival in 14 patients with an incidental diagnosis of gallbladder cancer was 16 months; however, in eight of these patients who were considered to have had a potentially curative resection, the median survival was 38 months. DISCUSSION The prognosis for patients diagnosed preoperatively or at the time of cholecystectomy is very poor. Patients with an incidental finding of gallbladder cancer have a significantly better prognosis and should be considered for further radical re-resection.

Abstract
BACKGROUND Despite refinements in the management of choledochal cysts in children, an increasing number of patients present with ongoing symptoms in adult life. The aim of this study was to review the management of adult patients with choledochal cysts in a tertiary referral centre. METHOD A retrospective review was carried out of all adult patients presenting with choledochal cysts to this department between 1992 and 2000. Patient records were reviewed and detailed analyses were made of the clinical presentation, radiological and biochemical findings, anatomical anomalies, management, complications and outcomes. RESULTS Of 16 patients (12 women and 4 men; median age 23 years), 8 had undergone previous upper gastrointestinal operations before referral, including 5 who had had previous cyst drainage procedures. All patients underwent elective complete cyst excision with Roux-en-Y hepaticojejunostomy. There were no operative deaths and there was a low early postoperative morbidity rate (25%). There was no evidence of biliary malignancy in any cyst. During a median postoperative follow-up of 44 months, five patients (31%) continued to experience cholangitis and two of these required additional revisional procedures, but are now symptom-free. CONCLUSION Patients with choledochal cysts should be referred to specialised tertiary surgical units. Total choledochal cyst excision with Roux-en-Y hepaticojejunostomy is the treatment of choice. Patients with previous inadequate cyst excisional procedures should undergo revisional surgery, to reduce recurrent symptoms and the risk of developing cholangiocarcinoma.

Abstract
Abstract
Background
In a recent review of patients with potentially resectable pancreatic malignancy in the authors' unit, it was shown that inappropriate laparotomy was avoided in 35 per cent of patients as a direct result of laparoscopy combined with laparoscopic ultrasonographic staging, following previous spiral computed tomography (CT). However, subsequent analysis has suggested that laparoscopy may have added to information already available on the CT scan in as few as 22 per cent of patients. The aim of this study was to seek to define spiral CT scan criteria that might provide a more selective approach to laparoscopic staging.
Methods
Theatre records and the Lothian Surgical Audit Database were used to identify 124 patients between June 1995 and May 2000 whose investigations for suspected pancreatic tumours had included spiral CT followed by laparoscopic assessment (suspected tumour: pancreatic head, 88; periampullary, 25; lower bile duct, nine; duodenum, two). Each CT scan (with endoscopic retrograde cholangiopancreatography films if appropriate) was examined by a specialist pancreaticobiliary radiologist (D.N.R.) and graded ‘blindly’ according to a modified existing system for determining local resectability (0, no mass; A, fat plane between tumour and vessels; B, normal pancreas between tumour and vessels; C, mass convex to vessel; D, mass concave to vessel; E, vessel encircled; F, vessel occlusion) before the results were compared with findings at laparoscopy and laparotomy.
Results
In groups 0, E and F, only four (7 per cent) of 59 patients benefited from laparoscopic assessment, whereas 27 (42 per cent) of 65 patients avoided an inappropriate laparotomy in groups A–D as a result of improved staging. 0 A B C D E F n 27 24 4 8 29 28 4 Resection 20 9 3 1 9 – – Irresectable Laparoscopy 2 3 – – 3 2 – Laparoscopy + laparoscopic US 1 – – 1 4 2 2 Laparoscopic US – 5 – 1 8 11 2 No laparotomy (other) 1 1 – 2 1 1 – Inappropriate laparotomy 3 6 1 3 4 12 – US, ultrasonography
Conclusion
Based on these results, only patients graded A–D should undergo laparoscopic staging. By adopting this more selective policy in the future, the number of laparoscopic evaluations may be reduced by 48 per cent, while maintaining the efficacy of preventing inappropriate laparotomies at 42 per cent.

Abstract
Abstract
Background
Laparoscopic cholecystectomy is associated with bile duct injuries of a more severe nature than open cholecystectomy. This study examined the emerging role of hepatectomy in the management of major iatrogenic bile duct injuries in the laparoscopic era.
Methods
This was a retrospective cohort study of patients referred to a tertiary hepatobiliary unit with bile duct injuries over a 16-year period until April 2000. Data are expressed as median (range).
Results
Eighty-eight patients (34 men, 54 women) were referred during this interval; their median age was 55 (19–83) years. Injuries resulted from 50 laparoscopic cholecystectomies and 35 open cholecystectomies, with three occurring during gastroduodenal procedures. Laparoscopic surgery was associated with injuries of greater severity than open cholecystectomy: Bismuth type I–II, 32 per cent versus 69 per cent for the open operation; type III–IV, 66 per cent versus 31 per cent for the open procedure (P = 0·02, χ2 test). After referral 73 patients underwent definitive surgical interventions: 57 hepaticojejunostomies, 11 revisions of hepaticojejunostomy, two orthotopic liver transplants and three right hepatectomies. Two patients had subsequent hepatectomy following initial hepaticojejunostomy. Four of the five hepatectomies were for the management of injuries perpetrated at laparoscopic cholecystectomy. Criteria necessitating hepatectomy were liver atrophy on computed tomography (80 versus 11 per cent; P = 0·0001, χ2 test) and a greater incidence of angiographically proven vascular injury (40 versus 6 per cent; P = 0·006, χ2 test); in addition, type III–IV injuries were more frequent (60 versus 42 per cent) in the hepatectomy group. There were no procedure-related deaths. The overall postoperative morbidity rate was 13 per cent. Median hospital stay was 10 days.
Conclusion
Major hepatectomy allows the successful and safe repair of cholecystectomy-related bile duct injuries complicated by concomitant vascular injury, unilateral lobar atrophy and destruction of the biliary confluence.

Abstract
BACKGROUND Surgery for pancreatic necrosis complicating acute severe pancreatitis carries a high risk of mortality and may be influenced by a range of variables including patterns of referral, case selection and quality of care. METHODS An observational study of a consecutive series of 54 patients undergoing pancreatic necrosectomy in a specialist Hepatobiliary unit over an 8-year study period. Principal outcomes were organ dysfunction and physiological derangement in relation to surgery, microbial colonization of necrosis and relation to outcome, re-operation rates, requirement for peri-operative nutritional support, trends in mortality and survival analysis. RESULTS Necrosectomy was associated with statistically significant deterioration in immediate postoperative organ dysfunction scores (ANOVA P < 0.01). Infected necrosis was present in 36 (68%). Fungal colonization of necrosis was present in 5 (9%). Mortality in this subgroup was 80% (4 deaths). There was no association between bacterial colonization of necrosis and death in this study (P = 0.77; Fisher exact test; relative risk 0.9,95% confidence interval 0.54-1.54). Twenty patients (37%) required further surgical intervention with an average of 1.5 surgical procedures per patient. Twenty-three patients (43%) died. Patient survival to discharge was best predicted by admission APACHE-II score with relative risk of death increasing 14% for each unit increase in APACHE-II score at admission. CONCLUSIONS The results of the present study illustrate that there is no place for complacency in the surgical management of patients with severe acute pancreatitis. A clinical governance approach would promote pre-defined protocols between admitting hospitals and tertiary referral centres. Future research should target new interventions in patients with high admission APACHE-II scores in whom prognosis is particularly poor and explore the role of infection of necrotic tissue.

Abstract
Antiphospholipid syndrome can have various clinical presentations, two of the most common being arterial and venous thrombosis. It is, however, unusual for them to occur in combination. We report here a case of combined hepatic artery and segmental portal venous occlusion in a 32-year-old patient who was shown to have a lupus anticoagulant. There have been no previous reports of thrombosis occurring simultaneously in the coeliac axis and the portal vein. Computerised tomography, Doppler ultrasound scanning and selective visceral angiography were used to demonstrate the anatomical lesions. The patient was treated medically with unfractionated heparin leading to a favourable clinical outcome. The diagnosis and management of this case is discussed with reference to the current literature on visceral thrombosis and antiphospholipid antibody syndrome.

Abstract
BACKGROUND & AIMS Impaired pressor function in cirrhosis may be specific to certain agonists and vascular territories. This investigation determined whether responses to arginine vasopressin (AVP) and 5-hydroxytryptamine (5-HT) were impaired in hepatic arteries from cirrhotic patients. METHODS Cumulative concentration-response curves were produced for AVP (10(-11) to 3 x 10(-6) mol/L), 5-HT (10(-9) to 3 x 10(-5) mol/L), and potassium chloride (2.5 -120 mmol/L) in hepatic arteries from liver donors (noncirrhotic) and recipients (cirrhotic). The receptor stimulated by AVP was identified using a V(1)-receptor antagonist (d[CH(2)](5)Tyr[Me]AVP) and a selective V(2)-receptor agonist (desmopressin [DDAVP]). RESULTS Cirrhotic patients had a high heart rate (98 +/- 4 beats/min) and cardiac output (9.87 +/- 0.51 L/min) but low peripheral vascular resistance (711 +/- 35 dyn. s/cm(5)). None of the arteries had a functional endothelium. Maximal contraction (but not sensitivity) to AVP was smaller (P = 0.0002) in hepatic arteries from recipients (34.03% +/- 3.42% KCl) than donors (60.69% +/- 5.56% KCl). 5-HT-mediated contraction was enhanced in recipient hepatic arteries (88.81% +/- 5.43% KCl vs. 71.63% +/- 4. 46% KCl; P = 0.01), but sensitivities were similar (P = 0.20). KCl-mediated contractions were similar (P = 0.87) in both groups. Arteries did not respond to DDAVP, but d(CH(2))(5)Tyr(Me)AVP produced a concentration-dependent rightward shift in the response to AVP. CONCLUSIONS These results demonstrate a selective impairment of V(1) receptor-mediated contraction in denuded hepatic arteries from cirrhotic patients, suggesting an abnormality within the vascular smooth muscle.

Abstract
BACKGROUND Liver transplantation surgery is carried out in only a few selected centres in the UK. This study was performed with a view to identifying potential training opportunities available for the general and specialist higher surgical trainee, and also to assess the outcome following liver transplant surgery according to the grade of the surgeon performing the procedure. METHODS Data on 111 liver transplants with caval preservation undertaken consecutively in a single unit during a 32-month period were collected and analysed. The transplant procedures were grouped into those performed by consultants and those performed by supervised trainees. Survival was estimated by the Kaplan-Meier method. The Cox regression model was used to examine the influence of grade of the surgeon on survival. chi2 and independent sample t tests were used to identify significant preoperative, intraoperative and postoperative variables. RESULTS Trainees carried out 34 recipient hepatectomies (31 per cent), 47 implant procedures (42 per cent) and all 143 retrieval operations. The mean time taken by a supervised trainee to carry out a recipient hepatectomy and implantation was 183 and 44 min compared with 165 and 46 min for a consultant (P = 0. 22 and P = 0.44 respectively). The mean intraoperative red cell requirement was 8 units for both consultants and trainees (P = 0.85). The overall patient survival rate was 88 per cent at 3 years and the grade of the surgeon made no difference to survival or the occurrence of complications (P > 0.05). CONCLUSION The outcome following liver transplantation with caval preservation did not differ according to the grade of the surgeon performing the procedure. Extensive training opportunities are available to learn hepatobiliary and vascular surgical techniques in liver transplantation surgery.

Abstract
With the recent changes in surgical training and sub-specialisation, the role of surgical trainees in more advanced surgical procedures has come into question. In order to examine this further, we analysed the early outcome of patients in a single surgical unit undergoing pancreatic resections, with regard to the grade of the surgeon performing the operation. Between January 1994 and May 1996, data were collected prospectively on all the patients undergoing pancreatic resections with regards to the grade of the surgeon performing the procedure and the early outcome following the operation. Sixty-two patients underwent pancreatic resections for both benign and malignant diseases. Overall, 19 operations (31%) were performed by trainees under supervision, 14 of the 40 pancreatico-duodenectomies (35%) and 5 of the 19 left partial pancreatectomies (26%). All 3 total pancreatectomies were carried out by consultants. In the 43 patients operated upon by the consultants, there were 8 anastomotic leaks (19%) and 1 death. In the 19 patients operated upon by the supervised trainees, there were only 2 anastomotic leaks (11%) and no deaths. This series has demonstrated that in a unit with a major interest and large workload in pancreatic surgery, there appears to be no difference between a consultant and a supervised trainee in the early outcome following pancreatic resections.

Abstract
The 'New Deal' set out by the Department of Health in 1991, together with the introduction of specialist 6-year training grades by Calman in 1993, has resulted in a decrease in available training time for surgeons in the UK. There is also an emerging belief that surgical procedures performed by trainees might compromise patient outcome. This study examines the level of trainee experience in a specialist gastrointestinal unit and whether operation by a trainee surgeon adversely affects patient outcome. All patients in the University Department of Surgery, Royal Infirmary, Edinburgh, undergoing oesophagogastric, hepatic or pancreatic resection between January 1994 and December 1996 were entered into the study. The early clinical outcome (in-hospital mortality and morbidity, considered in three groups: anastomotic leak, other technique-related complications and non-technique-related complications) was evaluated with regard to the grade of surgeon (consultant or trainee) performing the operation. Of the 222 patients undergoing major upper gastrointestinal resection during the study period, 100 (45%) were operated on by trainees. Trainees were assisted and closely supervised by consultants in all but six resections. There was no major difference in mortality rate (consultant, 4.1% vs trainee, 5%), incidence of non-technique-related complications (consultant, 6.7% vs trainee, 7.1%), anastomotic leaks (consultant, 10.7% vs trainee, 5%) or technique-related complications (consultant, 18.9% vs trainee, 15%) between the two grades of surgeon. In a specialist unit, the early clinical outcome of patients undergoing major upper gastrointestinal resection by supervised trainees is no worse than in those operated on by consultants. Participation of trainees in such complex procedures enhances surgical training and does not jeopardise patient care.

Abstract
The influence of crossmatching in liver transplantation is still controversial, and at present, our unit does not alter management according to the result of standard lymphocytotoxicity testing. This study retrospectively assessed outcome of grafts transplanted in the presence of preformed antidonor cytotoxic antibody. One hundred twelve patients undergoing their first orthotopic liver transplantation had results available (mean follow-up: 18 months). Twelve patients had a positive crossmatch and 100 negative. The 1-year graft survival was 58% in the positive crossmatch group, compared with 81% in the negative crossmatch group (P = .02). The 1-year patient survival was 83% in the positive crossmatch group compared with 90% in the negative group (P = .41). Acute cellular rejection occurred in 6 of 7 (86%) grafts surviving more than 7 days in the positive crossmatch group compared with 46 of 88 (52%) grafts in the negative group (P = .09). However, episodes of further acute cellular rejection requiring treatment occurred in 4 of the 6 grafts in the positive crossmatch group but in only 4 of the 46 grafts with a negative crossmatch (P = .0006). The authors conclude that evidence exists in our population that preformed antidonor antibodies adversely affect the outcome of hepatic allografts but not patient survival.

Abstract
The results of a policy of selective cholangiography were assessed in 400 patients undergoing laparoscopic cholecystectomy. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) was performed in 81 patients (20 per cent) of whom 31 (38 per cent) showed definite or possible evidence of stones in the bile duct. Seventeen of the 400 patients underwent intraoperative cholangiography and the majority of these (12) were normal. After a minimum follow-up of 1 year, 17 patients (4 per cent) have had ERCP for suspected residual duct stones. Eight (2 per cent) of these revealed stones and all were successfully treated with sphincterotomy and duct clearance. Preoperative and postoperative ERCP was not associated with mortality or major morbidity. No major duct injury occurred and none was diagnosed within 2 years of operation. Routine intraoperative cholangiography is not a necessary part of laparoscopic cholecystectomy in the presence of an efficient and safe ERCP service.
