ObjectiveTo study the clinical manifestation, radiographic characteristics, and treatments of reactive lymphoid hyperplasia(RLH) of liver. MethodsThe clinical data and treatment process of 1 patient with RLH of liver in our hospital was analyzed retrospectively, and the other 49 cases reported in English literature were reviewed. ResultsThere were 33 pieces of case reports found in PubMed database. For all 50 patients, there were 45 female(90%) and 5 male(10%) patients, and the mean age was(57.6±14.0) years(15-85 years). Only 8 patients(16%) were discovered with multiple mass, the rest of them were solitary mass(84%). Of the 50 patients, 6 patients(12%) were discovered because of bellyache, 2 patients(4%) were discovered during operation, 2 patients(4%) were discovered by pathological examination after liver transplantation, 1 patient(2%) was discovered during autopsy, 39 patients were discovered during examination or reexamination. The tumors were located in the right lobe for 25 patients(50%), in the left lobe for 15 patients(30%), in the both lobes for 4 patients(8%), and in the caudal lobe for 1 patient(2%), while 5 cases(10%) were not given in the articles. Eleven patients(22%) had the history of malignancy, 15 patients(30%) were concomitant with autoimmune disease, and 5 patients(10%) were concomitant with virus hepatitis infection. Thirty-six patients(72%) were diagnosed as malignancy preoperatively, and 43 patients(86%) underwent surgical resection. ConclusionsRLH of liver is an extremely rare and benign condition which presents a female predilection and often concomitants with autoimmune disease and history of malignancy. Considering the risk of malignant transformation, surgical resection is recommended and further researches are necessary for better understanding of this disease.
ObjectiveTo analyze risk factors of intraoperative massive hemorrhage in patients with pancreatitis-induced sinistral portal hypertension (SPH) and to explore its strategies of treatment.MethodsThe clinical data of patients with pancreatitis-induced SPH admitted to the West China Hospital of Sichuan University from January 2015 to March 2018 were retrospectively analyzed. The intraoperative massive hemorrhage was defined as the blood loss exceeding 30% blood volume. The factors closely associated with the intraoperative massive hemorrhage were analyzed by the forward logistic regression model.ResultsA total of 128 patients with pancreatitis-induced SPH were enrolled in this study, including 104 males and 24 females, with an average age of 47 years old and a median intraoperative bleeding volume of 482 mL. Among them, 93 patients with pancreatitis-induced SPH caused by the pancreatic pseudocyst after acute pancreatitis and 35 caused by the chronic pancreatitis. There were 36 patients with history of upper gastrointestinal bleeding and 46 patients with hypersplenism. Thirty-six patients suffered from the massive hemorrhage. Among them, 30 patients underwent the distal pancreatectomy concomitant with splenectomy, 1 patient underwent the duodenum- preserving resection of pancreatic head, and 5 patients underwent the pseudocyst drainage. The univariate analysis showed that the occurrence of intraoperative massive hemorrhage in the patients with pancreatitis-induced SPH was not associated with the gender, age, body mass index, albumin level, upper gastrointestinal bleeding, hypersplenism, type of pancreatitis, course of pancreatitis, number of attacks of pancreatitis, size of spleen, maximum diameter of lesions in the splenic vein obstruction site, or number of operation (P>0.05), which was associated with the diameter of varicose vein more than 5.0 mm (χ2=19.83, P<0.01), the intraperitoneal varices regions (χ2=13.67, P<0.01), the location of splenic vein obstruction (χ2=5.17, P=0.03), the operation time (t=–3.10, P<0.01), or the splenectomy (χ2=17.46, P<0.01). Further the logistic regression analysis showed that the varicose vein diameter more than 5.0 mm (OR=6.356, P=0.002) and splenectomy (OR=4.297, P=0.005) were the independent risk factors for the intraoperative massive hemorrhage in the patients with pancreatitis-induced SPH.ConclusionsSplenectomy and having a collateral vein more than 5.0 mm in diameter are independent risk factors for intraoperative massive blood loss in surgeries taken on patients with pancreatitis-induced SPH. Attention should be paid to dilation of gastric varices and choice of splenectomy.
