Drainage of ascites in cirrhosis

For cirrhotic refractory ascites,diuretics combined with albumin and vasoactive drugs are the first-line choice for ascites management.However,their therapeutic effects are limited,and most refractory ascites do not respond to medication treat-ment,necessitating consideration of drainage or surgical interventions.Con-sequently,numerous drainage methods for cirrhotic ascites have emerged,including large-volume paracentesis,transjugular intrahepatic portosystemic shunt,peritoneovenous shunt,automated low-flow ascites pump,cell-free and concentrated ascites reinfusion therapy,and peritoneal catheter drainage.This review introduces the advantages and disadvantages of these methods in different aspects,as well as indications and contraindications for this disease.

Endoscopic“calabash”ligation and resection for small gastric mesenchymal tumors

BACKGROUND Gastric mesenchymal tumors(GMT)are identified as soft tissue neoplasms that arise from mesenchymal stem cells within the gastrointestinal tract.GMT pri-marily encompass gastric stromal tumors(GST),gastric leiomyomas,and gastric schwannomas.Although most GMT are benign,there are still potential malignant changes,especially GST.Thus,early surgical intervention is the primary treat-ment for GMT.We have designed a simple endoscopic“calabash”ligation and resection(ECLR)procedure to treat GMT.Its efficacy and safety need to be com-pared with those of traditional endoscopic techniques,such as endoscopic sub-mucosal excavation(ESE).AIM To assess the safety and effectiveness of ECLR in managing small GMT(sGMT)with a maximum diameter≤20 mm by comparing to ESE.METHODS This retrospective analysis involved patients who were hospitalized in our institution between November 2021 and March 2023,underwent endoscopic resection,and received a pathological diagnosis of GMT.Cases with a tumor diameter≤20 mm were chosen and categorized into two cohorts:Study and control groups.The study group was composed of patients treated with ECLR,whereas the control group was composed of those treated with ESE.Data on general clinical characteristics(gender,age,tumor diameter,tumor growth direction,tumor pathological type,and risk grade),surgery-related information(complete tumor resection rate,operation duration,hospitalization duration,hospitalization cost,and surgical complications),and postoperative follow-up were collected for both groups.The aforementioned data were subsequently analyzed and compared.RESULTS Five hundred and eighty-nine individuals were included,with 297 cases in the control group and 292 in the study group.After propensity score matching,the final analysis incorporated 260 subjects in each cohort.The findings indicated that the study group exhibited shorter operation duration and lowered medical expenses relative to the control group.Furthermore,the study group reported less postoperative abdominal pain and had a lower incidence of intraoperative perforation and postoperative electrocoagulation syndrome than the control group.There were no substantial variations observed in other parameters among the two cohorts.CONCLUSION ECLR is a viable and effective approach for managing sGMT.

Aluminum phosphate gel reduces early rebleeding in cirrhotic patients with gastric variceal bleeding treated with histoacryl injection therapy

BACKGROUND Esophageal-gastro varices bleeding(EGVB)is the most widely known cause of mortality in individuals with cirrhosis,with an occurrence rate of 5%to 15%.Among them,gastric varices bleeding(GVB)is less frequent than esophageal varices bleeding(EVB),but the former is a more critical illness and has a higher mortality rate.At present,endoscopic variceal histoacryl injection therapy(EVHT)is safe and effective,and it has been recommended by relevant guidelines as the primary method for the treatment of GVB.However,gastric varices after endoscopic treatment still have a high rate of early rebleeding,which is mainly related to complications of its treatment,such as bleeding from drained ulcers,rebleeding of varices etc.Therefore,preventing early postoperative rebleeding is very important to improve the quality of patient survival and outcomes.AIM To assess the efficacy of aluminium phosphate gel(APG)combined with proton pump inhibitor(PPI)in preventing early rebleeding after EVHT in individuals with GVB.METHODS Medical history of 196 individuals with GVB was obtained who were diagnosed using endoscopy and treated with EVHT in Shenzhen People's Hospital from January 2016 to December 2021.Based on the selection criteria,101 patients were sorted into the PPI alone treatment group,and 95 patients were sorted into the PPI combined with the APG treatment group.The incidences of early rebleeding and corresponding complications within 6 wk after treatment were compared between both groups.Statistical methods were performed by two-sample t-test,Wilcoxon rank sum test andχ2 test.RESULTS No major variations were noted between the individuals of the two groups in terms of age,gender,Model for End-Stage Liver Disease score,coagulation function,serum albumin,hemoglobin,type of gastric varices,the dose of tissue glue injection and EV that needed to be treated simultaneously.The early rebleeding rate in PPI+APG group was 3.16%(3/95),which was much lower than that in the PPI group(12.87%,13/101)(P=0.013).Causes of early rebleeding:the incidence of gastric ulcer bleeding in the PPI+APG group was 2.11%(2/95),which was reduced in comparison to that in the PPI group(11.88%,12/101)(P=0.008);the incidence of venous bleeding in PPI+APG group and PPI group was 1.05%(1/95)and 0.99%(1/101),respectively,and there was no significant difference between them(0.999).The early mortality rate was 0 in both groups within 6 wk after the operation,and the low mortality rate was related to the timely hospitalization and active treatment of all patients with rebleeding.The overall incidence of complications in the PPI+APG group was 12.63%(12/95),which was not significantly different from 13.86%(14/101)in the PPI group(P=0.800).of abdominal pain in the PPI+APG group was 3.16%(3/95),which was lower than that in the PPI group(11.88%,12/101)(P=0.022).However,due to aluminum phosphate gel usage,the incidence of constipation in the PPI+APG group was 9.47%(9/95),which was higher than that in the PPI group(1.98%,2/101)(P=0.023),but the health of the patients could be improved by increasing drinking water or oral lactulose.No patients in either group developed spontaneous peritonitis after taking PPI,and none developed hepatic encephalopathy and ectopic embolism within 6 wk of EVHT treatment.CONCLUSION PPI combined with APG can significantly reduce the incidence of early rebleeding and postoperative abdominal pain in cirrhotic patients with GVB after taking EVHT.
