Objective To explore the influence of cirrhotic portal hypertension and its complications on liver transplantation. Methods The literatures of the recent years on influence of hepatic cirrhotic portal hypertension on liver transplantation were reviewed. Results Splenomegaly, hypersplenism, portal vein thrombosis, portosystemic shunt and collateral flow in cirrhotic patients will increase the difficulty of liver transplantation and lead to more postoperative complications. Appropriate handling of these conditions can achieve a higher success rate of liver transplantation. Conclusion Correct management of end-stage cirrhotic portal hypertension and its complications can expand the indications of liver transplantation and improve long-term survival rates.
Objective To explore the cause, diagnosis, and treatment methods of portal vein thrombosis (PVT) after splenectomy. Methods The clinical data of 29 patients who were got splenectomy because of portal hypertension or traumatic splenic rupture from August 2002 to August 2008 in our hospital were analyzed retrospectively. Results Tweenty-seven patients with PVT were treated successfully, whose thrombi were absorbed completely or partially. One case died of peritonitis,septic shock,and multiple organ failure. One case died of hematemesis, hepatic coma,and multiple organ failure. Tweenty-four patients were followed up, the follow-up time was 0.5 to 3 years, the average was 2 years. Two cases died of massive hemorrhage, 1 case died of hepatic encephalopathy,and 1 case died of liver failure. Two cases occurred deep venous thrombosis in one year after treatment, and the remaining patients had no recurrence of venous thrombosis. Conclusions PVT have some connection with the raise of blood platelet and the hemodynamic changes of the portal vein system after splenectomy. Standardization of operation, early diagnosis, early line anticoagulant,and antiplatelet adhesion therapy are effective way to prevent and treat PVT.
Two hundred and thirty patients with solid hepatic space-occupying lesions (SHSOL), on whom hepatic resection was performed in Zhongshan hospital, were analyzed. We found that liver cirrhosis could be a diagnostic marker of hepatocellular carcinoma in patients with SHSOL, for which the sensitivity being 85.2%, the specificity 96.3%, and the positive predictive value 98.7%.
【Abstract】ObjectiveTo investigate the influence of CO2 pneumoperitoneum on intestinal mucosa permeability in rats with liver cirrhosis. MethodsFifty rats were randomly divided into following groups: control group (n=5), cirrhosis group(n=5) and pneumoperitoneum group (n=40); the pneumoperitoneum group was further divided into 8 mm Hg group(n=20) and 13 mm Hg group (n=20). Four time points were chosen, including 0.5, 2, 6, and 12 hours after the end of pneumoperitoneum. After rat models with cirrhosis were established successfully, the abdominal cavity was insufflated with CO2 and maintained under the pressures of 8 mm Hg and 13 mm Hg respectively for two hours. The portal venous blood was collected and the levels of Dlactic acid and endotoxin were measured. ResultsThe levels of endotoxin and Dlactic acid in cirrhosis group were much higher than those of control group(P<0.05). The levels of serum endotoxin and Dlactic acid in pneumoperitoneum group were higher than those of cirrhosis group(Plt;0.05) regardless of pressure and time point. The endotoxin level in 13 mm Hg group was higher than that of 8 mm Hg group on different time points (F=5.466, P<0.05), but there was no difference in Dlactic acid level between both of them(F=0.415,Pgt;0.05).ConclusionThe intestinal mucosa permeability is increased in rats with liver cirrhosis. It can be further increased under CO2 pneumoperitoneum with certain pressure and time and in a pressuredependent manner. The permeability can decrease after removal of pneumoperitoneum.
ObjectiveTo summarize the research progress of the pathogenesis, diagnosis and treatment of sarcopenia in liver cirrhosis. MethodThe relevant literatures on studies of the pathogenesis, diagnosis and treatment of sarcopenia in liver cirrhosis in recent years were searched and reviewed. ResultsThe sarcopenia was a major complication that could not be ignored in patients with liver cirrhosis, and was closely related to the patient’s quality of life and prognosis. Various mechanisms such as metabolic abnormalities, malnutrition, myostatin, hyperammonemia, hormonal regulation of muscle homeostasis, ubiquitin-proteasome system and autophagy, physical activity, and dysbiosis of the intestinal flora were involved in the development of sarcopenia. There were various diagnostic methods for sarcopenia, but a unified gold standard was still lacking. In addition, some progress had been made in the treatment of sarcopenia in recent years. ConclusionsAlthough current studies obtains preliminary results about relation between liver cirrhosis and sarcopenia, there still exists many problems to be solved. Further research in future will benefit diagnosis and treatment of patients with sarcopenia in liver cirrhosis.
Objective To investigate multi-slice spiral CT (MSCT) and MRI features of stasis cirrhosis and the diagnostic value of MSCT and MRI. Methods MSCT and MRI findings of 35 patients with stasis cirrhosis were studied. The size of liver and spleen, the diameter of hepatic vein (HV), enhancement pattern of liver parenchyma, contrast medium reflux in inferior vena cava (IVC) and (or) HV, ascites, number of varices and correlated abnormalities were reviewed. Results The volume index of liver and spleen of 35 patients was 4434.95 cm3 and 621.92 cm3 respectively. The mean diameter of HV of 27 patients (77.1%) was 3.61 cm and HV of other 8 patients (22.9%) were too small to show. Number of patients showed waves of borderline, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, varices and ascites was 5 (14.3%), 29 (82.9%), 20 (57.1%), 16 (45.7%), and 6 (17.1%), respectively. Correlated abnormalities included cardiac enlargement 〔4 cases (11.4%)〕, pericardium thickening 〔11 cases (31.4%)〕, and pericardial effusion 〔2 cases (5.7%)〕. Conclusions Stasis cirrhosis mainly demonstrate liver enlargement, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, and slight portal hypertension. MSCT and MRI play invaluable roles in diagnosis, differential diagnosis and etiological diagnosis of stasis cirrhosis.
ObjectiveTo introduce the technique of threedimensional portal venography of multidetector row spiral CT and its clinical application in the evaluation of the portosystemic collateral shunts of liver cirrhosis. MethodsAll relevant literatures were retrospectively reviewed on the application of twodimensional and threedimensional reconstruction techniques such as MIP, SSD, VRT of multidetector row spiral CT to demonstrate the collateral vessels of liver cirrhosis.ResultsThe distribution, pathway and anatomy of portosystemic collateral vessels were well shown by multidetector row spiral CT portal venography. Conclusion Multidetector row spiral CT portal venography provides excellent depiction of the anatomic characteristics of the collateral shunts and enables the continuous tracing of vascular structures, thus it is very helpful in the imaging evaluation of the collateral vessels of liver cirrhosis.
After analysising 15 patients with portal hypertension (PHT) in secondary biliary cirrhosis due to hepatolithiasis, the authors consider that the surgical procedure depends on indivedual’s specificity: majority of patients with PHT but no hemorrhage may be treated by removing the hepatobiliary stone, resolving the bile duct stricture and then reconstructing it as the first step. Whether or not to dispose of PHT depended on the postoperative condition. If the patient had previous hemorrhage and is accompanied by severe obstructive jaundice, splenectomy with shunt and simple biliary external drainage is the choice and removal of stone with biliary tract reconstruction will be performed in the second stage. Meanwhile, it is very important to monitor perioperative condition of the patient and treat the complications.
【Abstract】ObjectiveTo prospectively study the effects of recombinant human growth hormone (rhGH) on the changes of liver function and nutritional metabolism in postoperative patients with cirrhosis and portal hypertension. MethodsFortyeight cases with liver cirrhosis and portal hypertension who were collected from February 2003 to January 2004 were randomly divided into 2 groups (24 patients in each group). All patients were given the low calorie parenteral nutrition support and exogenous albumen after operations. Patients in the study group received rhGH from the second day after operations and physiological saline was used in the control group instead. The effects were evaluated in terms of protein metabolism, liver function, blood glucose level at different phases before and after the intervene. Death rates of in patients were also recorded in both groups. ResultsThe rising amplitude of albumen in the study group had been significantly larger than that of the control group from the seventh day after intervene (P<0.05). The blood transaminase levels (ALT,AST) in the study group were significantly lower than that of the control group (P<0.05). The blood glucose level of both groups decreased over time and returned to normal on day 14 after intervene, but there was no significant difference for both glucose and plasma bilirubin level between the two groups before and after the intervene (Pgt;0.05). The rates of death were similar, although the length of stay in the study group was much shorter than that of the control group. ConclusionrhGH may inhibit the catabolism, correct hypoproteinemia, improve liver function for postoperative patients with cirrhosis and portal hypertension, and reduce their length of stay.
42 Wistar rats were divided into three groups at random, liver cirrhosis (LC), portal vein stricture (PVS) and sham operation (SO) group. The changes of barrier capability of gastric mucosa in portal hypertensive rats were observed. The results demonstrated: the splanchnic blood flow of the portal hypertensive rats increased, as compared with the normal control group (P<0.001), but actually gastric mucosa was under the condition of ischemia. Mucosa of gastric wall glycoprotein and PGE2 of gastric mucosa decreased, as compared with the normal control (P<0.01); and more seriously decreased in cirrhotic portal hypertensive rats, there was no significant difference about amount of the basal acid secretion (BAS) among the three groups, but the amount of H+ backdiffusion (H+BD) was obviously increased, as compared with the normal control group (P<0.001). The amount of H+BD of cirrhotic portal hypertensive rats was the highest among this three groups. The results suggest that the barrier capability of gastric mucosa with portal hypertension is lower than that of the normal control group and much lower with cirrhotic portal hypertensive rats. The portal hypertensive gastropathy is associated with the lower capability of defense of gastric mucosa. The condition of liver function contributes to the change of barrier capability of gastric mucosa.
