Patients with chronic liver diseases are at great risk for both morbidity and mortality during the post-operative period due to the stress of surgery and the effects of general anaesthesia.

The main aim of this study was to evaluate the value of Model for End-stage Liver Disease (MELD) score, as compared to Child-Turcotte-Pugh (CTP) score, for prediction of 30- day post-operative mortality in Egyptian patients with liver cirrhosis undergoing non-hepatic surgery under general anaesthesia.

A total of 60 patients with Hepatitis C Virus (HCV) - related liver cirrhosis were included in this study. Sensitivity and specificity of MELD and CTP scores were evaluated for the prediction of post-operative mortality. A total of 20 patients who had no clinical, biochemical or radiological evidence of liver disease were included to serve as a control group.

The highest sensitivity and specificity for detection of post-operative mortality was detected at a MELD score of 13.5. CTP score had a sensitivity of 75%, a specificity of 96.4%, and an overall accuracy of 95% for prediction of post-operative mortality. On the other side and at a cut-off value of 13.5, MELD score had a sensitivity of 100%, a specificity of 64.0%, and an overall accuracy of 66.6% for prediction of post-operative mortality in patients with HCV- related liver cirrhosis.

MELD score proved to be more sensitive but less specific than CTP score for prediction of post-operative mortality. CTP and MELD scores may be complementary rather than competitive in predicting post-operative mortality in patients with HCV- related liver cirrhosis.

Cholecystectomy is associated with increased risks in patients with cirrhosis. The well-established advantages of laparoscopic surgery may be offset by the increased risk for complications relating particularly to portal hypertension and coagulopathy.

A systematic search was undertaken to identify studies comparing open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) in patients with cirrhosis. A meta-analysis was performed of the available randomized controlled trials (RCTs).

Forty-four studies were analysed. These included a total of 2005 patients with cirrhosis who underwent laparoscopic (n= 1756) or open (n= 249) cholecystectomy, with mortality rates of 0.74% and 2.00%, respectively. A meta-analysis of three RCTs involving a total of 220 patients was conducted. There was a reduction in the overall incidences of postoperative complications and infectious complications and a shorter length of hospital stay in LC. However, frequencies of postoperative hepatic insufficiency did not differ significantly.

There are few RCTs comparing OC and LC in patients with cirrhosis. These studies are small, heterogeneous in design and include almost exclusively patients with Child-Pugh class A and B disease. However, LC appears to be associated with shorter operative time, reduced complication rates and reduced length of hospital stay.

Patients with primary sclerosing cholangitis (PSC) have an increased risk for gallbladder cancer. We aimed to define the postoperative outcomes in PSC patients after cholecystectomy and determine if size of a gallbladder lesion on imaging predicts the presence of neoplasia.

We conducted a retrospective review of patients with PSC who underwent cholecystectomy at Mayo Clinic between 1 January 1995 and 31 December 2008. Patients with a prior history of a liver transplant or cholangiocarcinoma were excluded.

A total of 57 patients were included in our primary analysis during the early postoperative period. The most common indication for undergoing a cholecystectomy was the presence of a gallbladder polyp or mass. The sensitivity and specificity of a gallbladder lesion of 0.80 cm and the presence of gallbladder neoplasia was 100% (95% confidence interval (CI) 77-100%) and 70% (95% CI 35-93%), respectively. Of the patients, 23 (40%) had an early postoperative complication. The Child-Pugh score was the only predictor of postoperative outcomes in the multivariate model (odds ratio 1.78, 95% CI 1.11-3.12, P=0.02).

Cholecystectomy in patients with PSC is associated with a high morbidity. Gallbladder polyps <0.80 cm are unlikely to be malignant and observation of these small polyps should be considered. A higher Child-Pugh score was associated with early postoperative complications.

Pancreatic surgery is associated with an increased risk of postoperative complications. We therefore investigated the impact of an additional liver function disorder on the postoperative outcome using a case-control study of patients with or without liver cirrhosis who underwent pancreatic surgery at our department.

Between 1998 and 2008, 1,649 pancreatic resections were performed. Of these, 32 operations were performed in patients who also suffered from liver cirrhosis (30× Child A, 2× Child B). For our case-control study, we selected another 32 operated patients without cirrhosis who were matched according to age, sex, diagnosis and tumor classification. The following parameters were compared between both groups: operating time, number of transfusions, duration of ICU and hospital stay, incidence of complications, rate of reoperation, mortality.

Patients with cirrhosis experienced complications significantly more often (69 vs. 44%; p = 0.044), especially major complications (47 vs. 22%; p = 0.035) requiring reoperation (34 vs. 12%; p = 0.039). These patients also had a prolonged hospital stay (27.9 vs. 24.3 days) and a significantly longer ICU stay (8.6 vs. 3.7 days; p = 0.033), and required twice as many transfusions. Overall, 3 patients died following surgery, 1 with Child A (3% of all Child A patients) and 2 with Child B cirrhosis.

Pancreatic surgery is associated with an increased risk of postoperative complications in patients with liver cirrhosis, and is therefore not recommended in patients with Child B cirrhosis. In Child A cirrhotic patients the mortality is, however, comparable to noncirrhotic patients. Due to the demanding medical efforts that these patients require, they should be treated exclusively in high-volume centers. and IAP.

Laparoscopic cholecystectomy is a challenging procedure in patients with cirrhosis. This study aims to evaluate the safety and outcome of laparoscopic cholecystectomy in patients with cirrhosis and examines the value of model for end-stage liver disease (MELD) score and Child-Pugh classification in predicting morbidity.

From January 1995 to July 2008, 220 laparoscopic cholecystectomies were performed in cirrhotic, Child-Pugh class A and B patients. Indications included symptomatic gallbladder disease and cholecystitis. MELD score ranged between 8 and 27. Child-Pugh class and MELD score were preoperatively calculated and associated with postoperative results. Data regarding patients and surgical outcome were retrospectively analyzed.

No deaths occurred. Postoperative morbidity occurred in 19% of the patients and included hemorrhage, wound complications, and intra-abdominal collections controlled conservatively. Intraoperative difficulty due to liver bed bleeding was experienced in 19 patients. Conversion to open cholecystectomy was necessary in 12 cases. Median operative time was 95 min. Median hospital stay was 4 days. Patients with preoperative MELD score above 13 showed a tendency for higher complication rate postoperatively. Child-Pugh classification did not seem to predict morbidity effectively.

Laparoscopic cholecystectomy can be performed safely in selected patients with cirrhosis Child-Pugh A and B and symptomatic cholelithiasis with acceptable morbidity. Some of its advantages are shorter operative time and reduced hospital stay. MELD score seems to predict morbidity more accurately than Child-Pugh classification system.

Management of the surgical patient with liver disease begins with a careful preoperative assessment (Fig. 1). Any clues to liver disease on history and physical examination should be investigated to ascertain the cause of the clinical finding. More data on surgical patients with unexpected liver disease are now available. Patients undergoing emergent surgery are at significant risk of developing liver dysfunction. Child's class still correlates strongly to postoperative complications. Cornerstones of perioperative management in these patients are medical treatment of complications of chronic liver disease, such as ascites; coagulopathy; prevention of encephalopathy; and rapid treatment of dangerous postoperative complications, such as acute acalculous cholecystitis. Evolving knowledge of the effects of anesthesia, improving surgical techniques, and use of better diagnostic tests will help in the reduction of perioperative complications in these patients.

Reported mortality for open cholecystectomy in patients with cirrhosis ranges from 10% to 80%. Laparoscopic cholecystectomy has gained acceptance in the general population and has become the procedure of choice for symptomatic cholelithiasis. We reviewed our experience with the use of laparoscopic cholecystectomy in this group.

We did a retrospective review of the records of 25 consecutive laparoscopic choleoystectomy procedures performed on cirrhotic patients from May 1992 to July 1996.

There were no mortalities in our group. All procedures were completed laparoscopically. Mean length of stay was 1.7 days (range, 1 to 8 days). Morbidity consisted of wound hematomas, pneumonia, and ascites for a rate of 32%. Only patients with Child's Class A and Class B cirrhosis were operated on.

Laparoscopic cholecystectomy can be performed safely in cirrhotic patients with well compensated liver function.

34 cirrhotic patients who underwent either cholecystectomy alone or in conjunction with common duct exploration were retrospectively reviewed. In Child A and B patients morbidity was low and there were no postoperative deaths. However, all patients who underwent additional cholecystectomy during the non-shunting operation for esophageal varices required blood transfusion. Cholecystectomy in Child C patients is frequently associated with considerable intraoperative bleeding and subsequent postoperative complications. In the 23 patients who were not operated upon for gallstones, no patients developed symptomatic biliary disease. Ultrasonographically, most of these gallstones were strongly suspected to be black stones. Elective surgical intervention for symptomatic Child A and B patients would normally be warranted, but hemorrhage and resulting complications due to additional cholecystectomy for asymptomatic gallstones during the non-shunting operation should be minimized. An additional cholecystectomy should be considered, provided such a cholecystectomy is thought to be easily performed judging from the degree of development of collateral circulation around the hepatoduodenal ligament and unless black stones are suspected ultrasonographically. For symptomatic gallstones in Child C patients every type of medical treatment should be attempted. After considering the bleeding tendency or ascites, percutaneous transhepatic gallbladder drainage is considered to be one of the safest treatments.

To evaluate the impact cirrhosis has on survival the records of 40 cirrhotic trauma victims from the registries of two Level 1 trauma centers were reviewed and probability of survival calculated using the TRISS methodology. Mechanism of injury, anatomic location, involvement of single or multiple sites, presence of ascites, elevations in serum glutamic oxaloacetic transaminase (SGOT), alkaline phosphatase, serum bilirubin, prothrombin time (PT), and hypoalbuminemia were tabulated for each patient. Contingency tables were created for injury and hepatic parameters, as related to survival, and subjected to chi square analysis. Loglinear analysis was performed on all significant parameters to evaluate the independent effects of injury characteristics and hepatic insufficiency on survival. Predicted survival was 93%; observed survival was 70% (Z = -6.92; p less than 0.001). Cause of death was multiple-system organ failure (9) and closed head injury (3). Admission markers of poor outcome included one or more of the following: ascites, elevated PT or bilirubin, history of motor vehicle accident, multiple trauma, or blunt abdominal trauma requiring laparotomy. Loglinear analysis revealed that the presence of ascites, elevated PT, or bilirubin, further diminished the rate of survival for any individual injury characteristic. We concluded that survival among cirrhotic trauma victims was significantly lower than predicted. In addition the presence of hepatic insufficiency further diminishes survival, regardless of the injury sustained.
