- BACKGROUND AND AIMS: Non-operative management (NOM) of blunt liver trauma is currently, if possible, the preferred treatment of choice. The present study evaluates the experience of blunt liver injury in adults in a Swedish university hospital. MATERIAL AND METHODS: Forty-six patients with blunt liver trauma were treated from January 1994 through to December 2004. Patient charts were reviewed retrospectively to examine injury severity score (ISS), liver injury grade, diagnostics, treatment and outcome. RESULTS: Thirty-five patients (76%) were initially treated non-operatively and 11 (24%) patients had immediate surgery. In four (11%) patients, NOM failed and the patients required surgery 8-72 h after admission. Patients failing non-operative care had a significantly lower systolic blood pressure on admission as compared with patients with successful NOM (P = 0.001). Patients immediately operated upon had higher ISS (P < 0.001) and were haemodynamically unstable to a greater extent (P < 0.001) as compared with patients initially considered for NOM. Operated patients had increased transfusion requirements (P < 0.001), longer total hospital stay (P = 0.011) and stay in the intensive care unit (ICU) unit (P < 0.001) as compared with NOM. One immediately operated and one failed NOM died (total mortality 4%). Seventeen patients in the NOM group were successfully treated without surgery despite the presence of at least one described risk factor. CONCLUSIONS: Most patients with blunt liver trauma can be treated without surgery, and non-operative management may be performed even in the presence of established risk factors.

- Background: Fast-track (FT) programmes represent a series of multimodal concepts that may reduce surgical stress and speed up convalescence after surgery. The aim of this systematic review was to evaluate FT programmes for patients undergoing hepatopancreatic surgery. Methods: PubMed, Embase and the Cochrane Library databases were searched for studies of FT vs. conventional recovery strategies for liver and pancreatic resections. Results: For liver surgery, three cohort studies were included. Primary hospital stay was significantly reduced after FT care in two of the three studies. There were no significant differences in rates of readmission, morbidity and mortality. For pancreatic surgery, three cohort studies and one case-control study were included. Primary hospital stay was significantly shorter after FT care in three out of the four studies. One study reported a significantly decreased readmission rate (7% vs. 25%; P= 0.027), and another study showed lower morbidity (47.2% vs. 58.7%; P < 0.01) in favour of the FT group. There was no difference in mortality between the FT and control groups. Conclusions: FT rehabilitation for liver and pancreatic surgical patients is feasible. Future investigation should focus on optimizing individual elements of the FT programme within the context of liver and pancreatic surgery.

- Objectives: Sinusoidal injury (SI) after oxaliplatin-based therapies for colorectal liver metastasis (CRLM) can increase postoperative morbidity. Preoperative methods to estimate SI are lacking. The aim of this study was to identify SI by evaluating portal vein haemodynamics. Methods: Magnetic resonance imaging flowmetry (MRIF) was used to estimate portal vein haemodynamics in 29 patients with CRLM before liver surgery. Sinusoidal injury was evaluated from resected non-tumorous liver parenchyma according to the combined vascular injury (CVI) score of ≥3. Results: All patients with SI (six of 29) received oxaliplatin; however, a significant association could not be proven (P= 0.148). Oxaliplatin-treated patients showed portal vein dilatation in both the SI and non-SI groups compared with patients who had not received oxaliplatin (Bonferroni corrected P= 0.003 and P= 0.039, respectively). Mean portal velocity tended to be lower in patients with SI compared with oxaliplatin-treated patients without SI (Bonferroni corrected P= 0.087). A mean portal velocity of ≤14.35 cm/s together with a cross-section area of ≥1.55 cm2 was found to predict SI with sensitivity of 100% and specificity of 78%. Conclusions: Oxaliplatin treatment was associated with portal vein dilatation. Patients with SI showed a tendency towards decreased mean portal flow velocity. This may indicate that SI is associated with an increased resistance to blood flow in the liver parenchyma. Portal vein haemodynamic variables estimated by MRIF can identify patients without SI non-invasively.

- Objective: The purpose of this study was to explore the accuracy of elevated liver function values, age, gender, pancreatitis and cholecystitis as predictors of common bile duct stones (CBDS). Methods: All patients operated on for gallstone disease over a period of 3 years in a Swedish county of 302 564 citizens were registered prospectively. Intraoperative cholangiography (IOC) was used to detect CBDS. Results: A total of 1171 patients were registered; 95% of these patients underwent IOC. Common bile duct stones were found in 42% of patients with elevated liver function values, 20% of patients with a history of pancreatitis and 9% of patients with cholecystitis. The presence of CBDS was significantly predicted by elevated liver function values, but not by age, gender, history of acute pancreatitis or cholecystitis. A total of 93% of patients with normal liver function tests had a normal IOC. The best agreement between elevated liver function values and CBDS was seen in patients undergoing elective surgery without a history of acute pancreatitis or cholecystitis. Conclusions: Although alkaline phosphatase (ALP) and bilirubin levels represented the most reliable predictors of CBDS, false positive and false negative values were common, especially in patients with a history of cholecystitis or pancreatitis, which indicates that other mechanisms were responsible for elevated liver function values in these patients.

- Acute pancreatitis (AP) is a common disease that has a mild to moderate course in most cases. During the last decade, a change in diagnostic facilities as well as improved intensive care have influenced both morbidity and mortality in AP. Still, however, a number of controversies and unresolved questions remain regarding AP. These include prognostic factors and how these may be used to improve outcome, diagnostic possibilities, their indications and optimal timing, and the systemic inflammatory reaction (systemic inflammatory response syndrome - SIRS) and its effect on the concomitant course of the disease and potential development of organ failure. The role of the gut has been suggested to be important in severe AP, but has recently been somewhat questioned. Despite extensive research, pharmacological and medical intervention of proven clinical value is scarce. Various aspects on surgical interventions, including endoscopic sphincterotomy, cholecystectomy and necrosectomy, as regards indications and timing, will be reviewed. Last, but not least, are the management of late complications and long-term outcome for patients with especially severe AP.

- Introduction. Iatrogenic bile duct lesions following cholecystectomy represent a feared complication occurring in up to 0.9%. The aim of the present study was to estimate the total cost associated with both minor and major bile duct injuries. Material and methods. Detailed information on 24 consecutive patients, out of which 14 were considered to have minor and 10 patients considered as having major bile duct injury, provided the underlying information that rendered calculations on average individual costs for both groups of injuries. Results and discussion. Calculating individual costs for minor and major bile duct injuries with actual incidences of cholecystectomies performed and the incidence of iatrogenic bile duct injury demonstrated that the total costs, including in-hospital cost, sick leave and loss of production, were substantial. For the management of minor bile duct injuries costs were within the range of 136,787-159,585 EUR and for the management of major bile duct injuries from 336,903-449,204 EUR per million inhabitants and year. The total costs for the management of all types of bile duct injuries were thus within the range of 473,690-608,789 EUR per million inhabitants annually for the society.

- Background. Immunomodulation may represent a potential way to improve surgical outcome. These types of interventions should be based on detailed knowledge of the underlying mechanisms involved. The aim of the present review is to summarize some experience on the acute phase response, potential ways of intervention and experiences from critical illness and HPB disease. Discussion. Mechanisms of the acute phase response are discussed including the individual parameters and local changes that take part. Mechanisms involved in failure of the gut barrier are presented and include changes in gut barrier permeability, effects on gut-associated immunocompetent cells, and systemic implications. As examples of HPB disease, mechanisms of the acute phase response and potential ways of intervention in obstructive jaundice and acute pancreatitis are discussed. Nutritional pharmacology and lessons learned from immunomodulation and immunonutrition in critical illness and major abdominal surgery, including upper GI and HPB surgery, are referred to. Overall, immunomodulation represents a potential tool to improve results but requires a thorough mapping of underlying mechanisms in order to achieve individualized treatment or prevention based on patients' specific needs.
