Abstract
OBJECTIVE Incidence of intrahepatic mass-forming cholangiocarcinoma (IMCC) is increasing worldwide, especially in patients with chronic liver disease. The small and the histologically well-differentiated IMCCs in chronic liver disease could be arterially hypervascular lesions with/without washout on computed tomography (CT) and magnetic resonance imaging (MRI), mimicking typical hepatocellular carcinoma (HCC). The aim of this work is to evaluate contrast enhancement (CE) patterns of IMCCs at quadri-phasic multidetector CT (4-MDCT) and MRI, using imaging-clinicopathologic correlation. PATIENTS AND METHODS The 4-MDCT and MR images of 56 histologically confirmed IMCCs were retrospectively evaluated for tumor morphology and enhancement features. Enhancement pattern was defined according to the behavior of the nodule in arterial (AP), portal venous (PVP) and equilibrium phases (EP), and dynamic pattern was described according to enhancement progression throughout the different phases. Arterial and dynamic enhancement patterns were correlated with chronic liver disease, tumor size and histological differentiation. RESULTS Most of the nodules were peripherally hyperenhancing (50%) on AP, and partially hyperenhancing on PVP (67.9%) and EP (80.3%). Forty-six (82.1%) IMCCs showed progressive CE, 7 (12.5%) stable CE and 3 (5.4%) wash-out. In normal liver there were 34 nodules with progressive and 3 with stable CE, whereas in chronic liver disease there were 12 IMCCs with progressive, 4 with stable and 3 with washout pattern (p = 0.01); IMCCs with progressive CE were more differentiated than IMCCs with stable CE and wash-out (p = 0.02). CONCLUSIONS The most prevalent enhancement pattern of IMCCs was arterial rim enhancement followed by progressive and concentric filling. The stable and the washout patterns were more frequent in poorly differentiated IMCCs. Contrast washout was observed only in IMCCs emerging in chronic liver disease with a risk of misdiagnosis with HCC.

Abstract
AIM The properties of plasma cholinesterase (CHE) are partly undiscovered. Equally unknown are the correlations between changes in CHE and other blood variables during the acute phase response related to acute surgical and critical illness. METHODS Data from 432 measurements of CHE and other variables performed in 92 patients were systematically evaluated and processed by regression analysis. RESULTS There was a strong direct correlation between CHE and albumin (r=0.77, P<0.0001). CHE was also directly correlated to cholesterol, iron binding capacity, hematocrit, prothrombin activity, and inversely correlated to bilirubin and to presence of sepsis or liver dysfunction (P<0.0001 for all). Postoperatively CHE decreased to about 60% of the preoperative value, remaining directly related to it (r=0.69, P<0.0001), and decreasing further in the presence of sepsis or liver dysfunction, with slow reversal of the decrease during recovery from illness. In parenterally fed septic patients the decrease in CHE was moderated by increasing the amino acid dose (P<0.0001). CONCLUSION In acute surgical and critical illness CHE mostly behaves as a negative acute phase reactant, independently of the modifications related to other already known factors. This should be taken into account when interpreting the implications of decreased CHE in the clinical setting.

Abstract
Hilar cholangiocarcinoma (HC) is a rare tumor which has to be distinguished by intrahepatic cholagiocarcinoma invading hepatic hilum because the former has better prognosis then the latter. Patients with HC are difficult to manage because many challenging issues remain in the treatment of this tumour regarding correct diagnosis and therapeutic strategy. HC is resectable in about 30% of cases, but operative risk is highly influenced by septic complications of preoperative biliary drainage and by the need of major liver resection associated with biliary resection. We report the results of 43 resected patients (28 M/15 F; mean age 60 years, range 33-78), accounting for 29% of 149 patients with HC. Symptomless jaundice was the most common clinical presentation (87%; 130 patients). Biliary stricture was classified according to the Bismuth-Corlette classification as type 1 in 3 patients (7%); type 2 in 12 patients (28%); type 3 in 28 patients (65%). Ten patients underwent preoperative right portal vein embolization. Main biliary confluence excision associated with major hepatectomy was performed in 40 patients (93%), with R0 resection rate by 77%. Postoperative mortality rate was 6.9% (3 patients). Morbidity rate was 52.5% (21 patients), being biliary fistula (38%) and liver failure (19%) the most frequent complications. Five-year overall and disease-free survival rate were 36.1% and 28.2, respectively. Surgical resection remains the only chance of cure for patients with HC. However, due to the complexity of surgery immediate results remain unsatisfactory with morbidity and mortality rates higher than those reported after liver resection for other malignancies. This is mainly related to septic complications, strictly linked to complications of preoperative biliary drainage. Selective biliary drainage, careful management of biliary drains, drainage of excluded ducts in case of cholangitis, bile culture guided antibiotic use and preoperative portal vein embolization are important factors to reduce the risk of cholangitis and of postoperative complications. Because of the significant perioperative risk, the demanding operative management and the rarity of this tumor, patients with HC should be referred to tertiary surgical centers.

Abstract
PURPOSE The purpose of this retrospective study was to evaluate the efficacy of right portal vein embolisation (PVE) in inducing contralateral liver hypertrophy before extended hepatectomy. MATERIALS AND METHODS Twenty-six consecutive patients, 14 with liver metastases (ten from colorectal cancer; four from carcinoid tumours) and 12 with biliary cancers (ten Klatskin tumours; one gallbladder tumour; one intrahepatic cholangiocarcinoma) with insufficient predicted future remnant liver (FRL) underwent right PVE to induce hypertrophy of the contralateral hemiliver prior to surgical resection. Total liver volume, tumour volume and FRL volume were calculated on a 3D workstation. The ratio of the FRL to the total functional liver volume was <30% in all patients. RESULTS The FRL volume increased by 5%-25% (15% on average) after right PVE in patients with liver metastases and by 9%-19% (14% on average) in patients with biliary cancers. In all patients, the ratio of FRL to functional liver volume was >or=30% after right PVE. No postoperative deaths due to severe liver failure occurred in the 20 patients who underwent extended hepatectomy. CONCLUSIONS Right PVE extends the indications for hepatectomy in patients with liver metastases and those with biliary cancers who have an insufficient potential hepatic functional reserve.

Abstract
AIM Liver resection (LR) and transplantation are the best options for treatment of hepatocellular carcinoma (HCC). We retrospectively analysed the experience obtained with LR for HCC in chronic liver disease patients. METHODS Up until May 2005, 248 patients with HCC were evaluated, and 113 resected. Of these, 97 with chronic liver disease, who underwent a total of 100 resections, form the basis of this study. Age of the patients was 65.6+/-9.2 years (range 32-81, male/female 76/21). In 77 cases there was unifocal and in 23 multinodular tumour; in 61 the size of the tumours was < or =5 cm and in 39>5 cm. Limited resections were performed in 15 cases, resections of 1-2 segments in 51, and major hepatectomies in 34. RESULTS Blood transfusions were required in 28 cases. Three patients died postoperatively, from liver failure and/or sepsis. Seventeen patients had nonlethal complications (mostly liver dysfunction, often with signs of amplified inflammatory response, including ARDS, without evident sources of sepsis). The 5- and 10-year survival rates were 44% and 24%, respectively. Decreased survival was significantly related to increasing number of tumour nodules and degree of liver fibrosis/presence of cirrhosis, and with the expression of markers of carcinogenesis in a sub-group who received this assessment. At 5 years the rate of liver HCC recurrence was 46%, however, death was unrelated to recurrence in 41% of non-survivors. CONCLUSIONS Surgery for HCC achieves acceptable early and long-term results. However, the patterns affecting perioperative outcome must be better understood, and the high recurrence rate warrants further trials to assess preventive treatments after LR.

Abstract
A large series of plasma albumin (ALB, g/dl) and simultaneous blood and clinical measurements were prospectively performed on 92 liver resection patients, and processed to assess the correlations between ALB, other plasma proteins, additional variables and clinical events. The measurements were performed preoperatively and at postoperative day 1, 3 and 7 in all patients, and subsequently only in those who developed complications or died. In patients who recovered normally ALB was 4.3 +/- 0.4 g/dl (mean +/- SD) preoperatively, 3.7 +/- 0.7 at day 1 and 3, and 3.9 +/- 0.4 at day 7. In patients with complications its decrease was more prolonged. In non-survivors it was 3.4 +/- 0.4 preoperatively, 3.0 +/- 0.4 at day 1, and then decreased further. Regression analysis showed direct correlations between ALB and pseudo-cholinesterase (CHE, U/l, nv 5300-13000), cholesterol (CHOL, mg/dl), iron binding capacity (IBC, mg/dl), prothrombin activity (PA, % of standard reference) and fibrinogen, an inverse correlation with blood urea nitrogen (BUN, mg/dl) for any given creatinine level (CREAT, mg/dl), and weaker direct correlations with hematocrit, other variables and dose of exogenous albumin. An inverse relationship found between ALB and age (AGE, years) became postoperatively (POSTOP) also a function of outcome, showing larger age-related decreases in ALB associated with complications (COMPL: sepsis, liver insufficiency) or death (DEATH). Main overall correlations: CHE = 287.4(2.014)(ALB), r = 0.73; CHOL = 16.5(1.610)(ALB) (1.001)(ALKPH), r = 0.71; IBC = 68.6(1.391)(ALB), r = 0.64; PA = 13.8 + 16.0(ALB), r = 0.51; BUN = 21.3 + 20.2(CREAT) - 6.2(ALB), r = 0.91; ALB = 5.0-0.013(AGE) - {0.5 + 0.003(AGE)( COMPL ) + 0.012(AGE)( DEATH )}( POSTOP ), r = 0.74 [p < 0.001 for each regression and each coefficient; ALKPH = alkaline phosphatase, U/l, nv 98-279, independent determinant of CHOL; discontinuous variables in italics label the change in regression slope or intercept associated with the corresponding condition]. These results suggest that altered albumin synthesis (or altered synthesis unable to compensate for albumin loss, catabolism or redistribution) is an important determinant of hypoalbuminemia after hepatectomy. The correlations with age and postoperative outcome support the concept that hypoalbuminemia is a marker of pathophysiologic frailty associated with increasing age, and amplified by the challenges of postoperative illness.

Abstract
BACKGROUND The aim of this study was to observe the effects of neoadjuvant therapy with irinotecan and 5-fluorouracil (5-FU)/folinic acid (FA) on the resection rate and survival of colorectal cancer patients with initially unresectable hepatic metastases. PATIENTS AND METHODS Forty patients received neoadjuvant chemotherapy comprising irinotecan 180 mg/m(2) administered intravenously (i.v.) on day 1, FA 200 mg/m(2) i.v. on days 1 and 2, 5-FU 400 mg/m(2) i.v. bolus on days 1 and 2, and 5-FU 1200 mg/m(2) as a continuous 48-h i.v. infusion on day 1. The treatment was repeated every 2 weeks and response was assessed every 12 weeks (six cycles). RESULTS The objective response rate to chemotherapy was 47.5% (n = 19), with two complete responses and disease stabilization in 11 (27.5.%) patients. Responses were unconfirmed for 11 patients undergoing surgery within 2 weeks. Treatment was well tolerated and adverse events were typical of the chemotherapy agents used. Twenty-seven (67.5%) patients reported hematological toxicity (35.0% grade 3/4) and 14 (35.0%) reported gastrointestinal toxicity (12.5% grade 3/4). Thirteen patients (32.5%) underwent potentially curative liver resection following chemotherapy. Chemotherapy was particularly effective in patients with large metastases on entry to the study. The median time to progression is 14.3 months and, at a median follow-up of 19 months, all patients are alive. CONCLUSIONS Neoadjuvant therapy with irinotecan combined with 5-FU/FA enabled a significant proportion of patients with initially unresectable liver metastases to undergo surgical resection. The effects of treatment on survival have yet to be determined.

Abstract
BACKGROUND Laparoscopic fenestration is considered the best treatment for symptomatic simple liver cysts. Conversely, the laparoscopic approach for the management of hydatid simple liver cysts is not widely accepted because of the risk for severe complications. Despite improvement in imaging techniques, the probability of preoperatively mistaking a hydatid liver cyst for a simple liver cyst remains about 5%. Therefore, laparoscopic fenestration, planned for a liver cyst could be performed unintentionally for an undiagnosed hydatid liver cyst. METHODS From January 2000 to January 2001, 15 patients with a diagnosis of liver cyst underwent laparoscopy for fenestration. In all cases preoperative serologic and imaging assessment had excluded hydatid liver cyst. To further exclude hydatid liver cyst, preliminary aspiration of the cyst with assessment of cystic fluid characteristics was performed. RESULTS In two patients with presumedly simple liver cyst, hydatid liver cyst was diagnosed instead at laparoscopy by aspiration of cystic fluid. The procedure was converted to laparotomy with subtotal pericystectomy. CONCLUSIONS The risk of misdiagnosing a hydatid liver cyst for a simple liver cyst, especially in the presence of a solitary cyst, should be considered before laparoscopic fenestration is performed. Intraoperative aspiration of cyst fluid before fenestration can minimize this risk, thus avoiding severe intraoperative and late complications.

Abstract
PURPOSE To quantify liver metastases and future remnant liver (FRL) volumes in patients who underwent right portal vein embolization (RPVE) and to evaluate the effects of this procedure on metastase growth. MATERIAL AND METHODS Nine patients with liver metastases from primary colon (n = 5), rectal lesions (n = 1) and carcinoid tumors (n = 3) underwent spiral CT to evaluate the ratio of the non-tumorous parenchymal volume of the resected liver to that of the whole liver volume (R2). Hand tracing was used to isolate the entire liver, the resected liver and metastase volumes. All patients with R2 > 60% underwent RPVE. RESULTS FRL exhibited a 101-336 cm3 (average 241 cm3) increase in volume 1 month after RPVE. One patient refused surgery for 2 months and before surgery the increase in volume of the FRL was similar to that of other patients (180.64 cm3). Percent metastases volume from colorectal carcinoma in embolized liver parenchyma increased from 62.4% to 138.4% at 1 month and to 562% at 2 months after RPVE. Metastase volume from carcinoid tumors was unchanged. CONCLUSION One month after RPVE, hypertrophy of the FRL is evident. In the embolized liver, there was a progressive increase in metastase volume from colorectal carcinoma while metastase volume from carcinoid tumor was unchanged in embolized and non-embolized liver.

Abstract
BACKGROUND Decreasing operative bleeding during liver resection, and thus extent of transfusions, has become a main criterion to evaluate operative results of hepatectomies. Hepatic pedicle clamping (HPC) is widely used for this purpose. The aim of the study was to evaluate safety, efficacy, technique, and contraindications of HPC during liver resections, comparing results of resections performed with or without HPC. METHODS Data from 245 liver resections were analyzed. In all, 125 resections were performed with HPC (group A), continuous in 100 cases and intermittent in 25 cases. The average duration of ischemia in group A was 39 +/- 20 minutes (range 7 to 107). In 20 cases (16%) ischemia was prolonged for 60 minutes or more. A total of 120 resections were performed without HPC (group B). Major resections were 53.6% in group A (67 cases) and 38.3% in group B (46 cases). Cirrhosis was present in 36 cases, 19 in group A and 17 in group B. RESULTS Operative mortality was nil. Postoperative mortality was 2.9%, morbidity 22.4%. Percentage of transfused cases (34.4% versus 60.0%; P <0.001) and number of blood units per transfused case (2 +/- 1 versus 4 +/- 3; P <0.001) were lower in group A versus group B. Similar figures were found by considering only major resections. Postoperative blood chemistries did not show important differences between the two groups, and postoperative alterations were related more to extent and complexity of the operation than to length of HPC. CONCLUSIONS HPC during liver resection is a safe and effective technique. This is demonstrated in a context where HPC is used continuously in most cases, intermittently in cases with impaired liver function and for more prolonged ischemia, and avoided in cases with limited bleeding, jaundice, and simultaneous bowel anastomoses.

Abstract
The demonstration that the liver can tolerate prolonged periods of normothermic ischaemia represents one of the most significant developments in liver resection surgery. It has permitted the application of techniques involving the temporary interruption of blood flow to the liver, with the aim of reducing bleeding during resection. This has led to a widening of the range of indications for the excision of lesions with a high risk of bleeding, and a reduction in the number of blood transfusions. This study analysed the results of 125 liver resections, 19 of which involved cirrhotic liver, carried out under conditions of normothermic ischaemia obtained by complete clamping of the hepatic pedicle either alone (112 patients) or together with caval clamping (13 patients). The mean duration of the ischaemia was 39 minutes (7-107). Eighty-two resections (65.6%) were carried out without transfusions; the mean number of units transfused in the other 43 cases (34.4%) was 2.1 +/- 1.3. The postoperative mortality rate was 0.9%; twenty-six patients (20.8%) developed postoperative complications and the incidence of liver failure was 5.6%. Postoperative disturbances of liver function tests were transitory and, in most cases, rapidly resolving.

Abstract
OBJECTIVE To assess correlates of hypocholesterolemia in moderate to critical surgical illness. DESIGN Prospective analysis of laboratory and clinical data. SETTING Department of surgery in a university hospital. PATIENTS 135 patients undergoing uncomplicated abdominal surgery or with sepsis, liver failure, hemorrhage, severe cholestasis, or multiple organ dysfunction syndrome (MODS). INTERVENTIONS Surgical and/or medical therapy according to clinical status. MEASUREMENTS AND MAIN RESULTS Determinations of total cholesterol, additional variables, and clinical data. Cholesterol decreased after surgery, in sepsis, liver failure, acute hemorrhage, and MODS and increased in cholestasis. Hypocholesterolemia correlated with decreases in plasma proteins and indices of hepatic protein synthetic adequacy, with hemodilution from blood loss, and was moderated or prevented by cholestasis. CONCLUSIONS These results help to explain the dynamics of the development, clinical relevance, and negative prognostic value of hypocholesterolemia in critical illness.

Abstract
Laparoscopic cholecystectomy has become the treatment of choice for gallbladder stones. As a matter of fact, the advantages related to the significant reduction of postoperative pain and the early mobilization of the patient, with a decrease of general surgical risk, have been well demonstrated. Also the complications of the surgical wound have been drastically reduced. On the contrary, iatrogenic trocar-related injuries represent specific complications of laparoscopic technique. However, the incidence of these complications, mostly the more severe ones, may be significantly reduced with routine use of the "open" technique. The increased incidence of common bile duct (CBD) injuries in laparoscopic cholecystectomy compared with the conventional technique may be partly explained with the learning curve related to the rapid diffusion of this new approach. An appropriate training, a meticulous operative technique and an early conversion to open procedure in case of intraoperative difficulties may reduce the risk of a CBD injury. In this work the authors' experience of 400 laparoscopic cholecystectomies without CBD injury and major complications is presented. Conversion rate was 5.2% in patients with simple symptomatic cholelithiasis and 37.5% in patients with acute or subacute cholecystitis.

Abstract
The contribution of various techniques to the diagnosis of hepatic angioma has been evaluated retrospectively in 32 patients. The features characterizing hepatic angioma in each technique (ultrasound, Doppler-ultrasound, computed tomography, angiography, scintigraphy, nuclear magnetic resonance) have also been evaluated. The results support the primary role of ultrasound for detecting hepatic lesions and for monitoring their evolution, because of the high sensitivity and of the easy availability of the technique. Doubts on the nature of the lesions should be resolved by using techniques with a higher specificity: scintigraphy for lesions larger than 3 cm in diameter, and computed tomography or nuclear magnetic resonance for lesions of even smaller sizes.

Abstract
BACKGROUND/AIMS Long term results of hepatic resection for metastases from colorectal cancer depend upon several factors which are related to both features of primary cancer and of metastases. The aim of this study was to evaluate prognostic factors that best correlate with long-term results. MATERIALS AND METHODS Fifty-eight hepatic resections were performed for colorectal cancer metastases. Long-term results were evaluated in relation to age of patients, features of primary tumor, features of metastases, section margin, number of intra-operative blood transfusions and execution of adjuvant chemotherapy. RESULTS Overall 5-year survival rate was 17%. 5-year survival rate in patients with stage B primary tumor was 63%, in patients with late metachronous metastases it was 28%, in patients with section margin > 1 cm it was 33% and in patients who did not receive intra-operative transfusions it was 45%. Patients with a solitary metastasis or with metastases sized less than 4 cm and those who received adjuvant chemotherapy also showed a better survival than the others. CONCLUSIONS Better results were observed in patients without nodal involvement of the primary tumor. Patients with a small solitary metachronous metastasis that appeared more than one year after the colorectal resection and resected with a section margin of more than 1 cm, also showed good results.

Abstract
BACKGROUND The "blind" insertion of the Veress needle for insufflation of the peritoneal cavity with subsequent closed placement of the first trocar during laparoscopic abdominal procedures can result in severe major vascular and visceral injuries. An open technique was proposed as an alternative method for insufflation in patients with abdominal scars to reduce the possibility of such complications. The aim of this article is to report the results of our experience with the routine use of open technique in laparoscopic surgery. STUDY DESIGN Open technique was routinely used and prospectively evaluated in 330 patients who underwent laparoscopic procedures. RESULTS Laparoscopic conversion was necessary in 25 out of 330 cases (7.6 percent): in 20 cases for unclear biliary anatomy during laparoscopic cholecystectomy, and in 5 cases for minor hemorrhage that could not be managed by laparoscopy. In the 305 procedures completed by laparoscopy, 11 patients (3.6 percent) had 13 postoperative complications. These complications were all of minor importance and were always unrelated to trocar insertion; in particular, no major vascular or visceral injuries were observed. CONCLUSIONS Routine use of open technique for pneumoperitoneum represents the best prevention of most of the severe trocar-related complications that are potentially avoidable.
