This retrospective, multi-institutional analysis showed that, in patients who undergo curative hepatectomy for HCC, the preoperative CONUT score is predictive of worse OS and RFS, even after propensity score matching analysis.
Clinicopathological features of patients with early gastric cancer can be used to identify those most at risk of developing either recurrence or a second primary cancer.
Controversy exists as to the nature of gastric perfusion in portal-hypertensive gastropathy. To investigate portal hemodynamics and gastric mucosal perfusion in cirrhotic patients with and without portal-hypertensive gastropathy, we subjected 56 cirrhotic patients with portal hypertension to portal vein catheterization, pneumatic pressure sensor technique, duplex sonography and laser Doppler flowmetry. Thirteen patients had portal-hypertensive gastropathy: In 10 it was mild, and in 3 it was severe. The presence of portal-hypertensive gastropathy seemed to be independent of age, sex, cause of cirrhosis or grade of esophageal varices. Portal venous pressure, esophageal variceal pressure, portal venous flow and congestion index in patients with portal-hypertensive gastropathy were not significantly different from the values in those without portal-hypertensive gastropathy. However, portal-variceal pressure gradient (subtracting esophageal variceal pressure from portal venous pressure) (p < 0.01) and the incidence of palisading-type esophageal varices on portography (p < 0.05) was increased in patients with portal-hypertensive gastropathy significantly more than in those without portal-hypertensive gastropathy. In the fundus, gastric mucosal blood flow was significantly higher in patients with portal-hypertensive gastropathy than in those without portal-hypertensive gastropathy, whereas in the corpus and the antrum the values were not significantly different. We suggest that the mucosa of the upper stomach in patients with portal-hypertensive gastropathy is congestive and highly perfused. The pathogenesis of portal-hypertensive gastropathy may be related to both congestion and hyperemia in the upper stomach.
A complete resection of a hepatocellular carcinoma (HCC) producing the granulocyte colony-stimulating factor (G-CSF) was performed and is reported here. The patient had a few general symptoms and complications, such as the paraneoplastic syndrome. He had marked granulocytosis, and his serum levels of G-CSF and interleukin-6 were elevated. The pathological findings of the resected specimen revealed poorly differentiated HCC with sarcomatous change and showed, immunohistochemically, staining of G-CSF. Only a few cases of G-CSF-producing HCC have been reported, and they resulted in rapid tumour growth and poor prognosis. The case presented here may be the first complete resection ever performed, but the patient's prognosis was similar to that observed in typical cases.
We report here complications of percutaneous transhepatic catheterization of the portal venous system in 170 Japanese patients with portal hypertension. All patients underwent percutaneous transhepatic portography and percutaneous transhepatic obliteration of oesophagogastric varices was also performed in 29 patients. After retraction of the catheter, the puncture canal was plugged with gelatin sponge in 150 subjects and with one steel coil in 20 others. The overall complication rate was 16.5%. Intraperitoneal bleeding occurred in 10.6% of patients and 2.9% required blood transfusion. In these patients with intraperitoneal bleeding, the gelatin sponge was used for plugging after retraction of the catheter, while in the 20 patients with a steel coil plug, haemoperitoneum never occurred. Right pleural effusion was recognized in 3.5% of patients, intraperitoneal bile leakage in 1.8% and deterioration of liver function due to arteriovenous fistula in 0.6%. By univariate and multivariate analyses, female gender was the only risk factor for intraperitoneal bleeding among 150 patients investigated by percutaneous transhepatic catheterization of the portal venous system with gelatin sponge plugging. Intraperitoneal bleeding is the most important complication in patients with portal hypertension; it is difficult to predict intraperitoneal bleeding before retraction of the catheter in patients for whom gelatin sponge is used. Thus, for patients undergoing percutaneous transhepatic catheterization of the portal venous system, close follow up is recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
