Abstract
INTRODUCTION Malignant ascites (MA) develops when malignant disease of the peritoneum causes excess fluid to accumulate in the abdominal cavity. It portends a poor prognosis and is associated with debilitating symptoms. While several palliative therapies exist, none have proven curative or free from side effects and complications. This review article describes experimental therapies on the horizon and the contemporary management of MA. MATERIALS AND METHODS A literature review was performed using MEDLINE/PubMed, in which studies of emerging or experimental therapies under investigation for the management of MA were reviewed. Current therapies were also reviewed to provide important context. Data, including study design, sample size, primary and secondary outcomes, and side effects were recorded and described. Studies were then categorized into distinct sections and subsections, with tables corresponding to each section. RESULTS Five current therapies, including paracentesis, diuretics, peritoneovenous shunting, permanent catheters, and intraperitoneal chemotherapy, are described. Their limitations in effectively managing MA are highlighted. The "Experimental therapies" section is subsectioned into several categories, with the major studies corresponding to each section thoroughly described regarding methods, results, and validity. A final section describes treatments for mucinous ascites, which has distinct characteristics. CONCLUSIONS While each of the experimental therapies described offers unique benefits and has demonstrated some promise in managing MA, they all have limitations that have thus far prevented any one of them from being routinely used in practice. MA remains a challenging condition to treat, warranting further research into novel therapies.

Abstract
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 treatment, necessitating consideration of drainage or surgical interventions. Consequently, 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.

Abstract
BACKGROUND There is a need for an improved version of the implantable catheter for malignant ascites in the abdominal cavity. OBJECTIVE New implantable catheters have been developed that drain ascites from the abdominal cavity to the bladder by applying pressure. Based on pigtail catheters, these newly designed catheters have silicone membranes and apertures. METHODS Experimental instruments controlled flow rates and water level to observe changes of the activation pressure and its cycle time along flow rates and turns of catheters. Furthermore, various normality tests, difference tests and non-parametric tests were investigated to observe statistical validity. RESULTS Cycle times were significantly affected by flow rate (3/4 cases of p< 0.05). The effects of flow rate on activation pressure, however, were not significant (1/4 case of p< 0.05). Cycle times were not significantly affected by the number of turns of the catheter (3/8 cases of p< 0.05). In contrast, the effects of the turns on activation pressure were significant (5/8 cases of p< 0.05). CONCLUSION Overall, there was no significant difference between cycle times for 1.5 turns and 2.0 turns of catheters. In addition, catheters with 1.5 turns have a lower activation pressure than catheters with 2.0 turns. It is possible to customize catheters based on the ascites excretion and urination rates of various terminal patients.

Spontaneous peritoneal drainage following paracentesis in a hospitalized patient with resolution of type 1 hepatorenal syndrome. Am J Med Sci 2022; 364:789-795.

Abstract
The hepatorenal syndrome develops in a small percentage of patients with advanced liver disease. The pathogenesis involves intravascular volume contraction secondary to pooling of blood in the splanchnic vessels, stimulation of the sympathetic nervous system and the renin-angiotensin-aldosterone pathway, and increased intra-abdominal pressure secondary to the formation of large volumes of ascitic fluid. The treatment options are limited, and liver transplant is the only definitive form of management. Here we suggest an alternative approach to treating hepatorenal syndrome based on the unexpected continuous peritoneal drainage in a 36-year-old man hospitalized with hepatic encephalopathy and hepatorenal syndrome. A total of 11.2 L ascitic fluid drained over 5 days from a paracentesis puncture site with marked improvement in renal function; the creatinine decreased from 3.3 mg/dL to 0.7 mg/dL and the BUN decreased from 42 mg/dL to 10 mg/dL. The discussion with this case report summarizes the pathogenesis, including the effect of intra-abdominal pressure, of the hepatorenal syndrome, outlines medical management, and makes a proposal for clinical study based on this case.

Abstract
Objective: Malignant ascites (MA) is a common complication of terminal cancer, which seriously affects the life quality and prognosis of patients. Both hyperthermic intraperitoneal chemotherapy (HIPEC) and traditional Chinese medicine (TCM) preparations have achieved significant efficacy in the treatment of MA. The treatment strategy of TCM combined with HIPEC has been gradually promoted and applied in China. The purpose of this systematic review and meta-analysis was to assess the efficacy of TCM combined with HIPEC in the treatment of MA.Methods: Randomized controlled trials (RCTs) of TCM combined with HIPEC for MA were searched from seven electronic databases. Two researchers used the Cochrane Collaboration’s tool to assess the risk of bias. Excel 2019 was used to establish a database for information extraction, RevMan 5.4 software was used to analyze the included test data, and STATA v16.0 was used to conduct Egger’s test to further detect publication bias.Results: A total of 19 studies involving 1,504 patients were included in this meta-analysis. The results showed that compared with the single use of HIPEC, TCM combined with HIPEC could significantly improve the clinical efficacy (RR = 1.51, 95% CI [1.40, 1.63], p < 0.00001) and karnofsky performance status (KPS) score (MD = 8.16, 95% CI [6.46, 9.85], p < 0.00001), reduce the ascites volume (MD = −156.98, 95% CI [−213.71, −100.25], p < 0.00001). However, there was no statistical significance in reducing abdominal circumference between TCM combined with HIPEC and HIPEC alone (MD = −1.8, 95% CI [−4.57, −0.97], p = 0.2).Conclusion: This study found that TCM combined with HIPEC had a beneficial therapeutic effect on MA. However, more standard, double-blind, multicenter RCTs are needed to further confirm the efficacy of TCM combined with HIPEC in the treatment of MA.Systematic Review Registration:https://www.crd.york.ac.uk/, identifier CRD42022319993.

Abstract
Background The alfapump® is an implantable class III medical device that pumps ascitic fluid from the peritoneal space to the urinary bladder from where it is excreted. The pump reduces or abrogates the need for repeated paracentesis in patients with recurrent or refractory ascites.
Aims To improve outcomes for alfapump® implantation and pre- and post-implant patient management in both clinical trial and real-world settings by development of consensus recommendations.
Methods The alfapump® working group consisting of hepatologists and surgeons with extensive experience in implantation of the alfapump® and patient management met on two occasions: (1) to determine the key areas where recommendations should be made; and (2) to discuss the experiences of the working group within those areas and formulate draft statements. Developed statements were submitted to the group and consensus sought on relevance and wording through a collaborative iterative approach in order to consolidate the recommendations into consensus statements. Only recommendations agreed upon unanimously were included. Results Twenty-three consensus recommendations were developed in the areas of pre-implantation procedure, (three statements), surgical implant procedure (11 statements), immediate post-implant care (three statements) and long-term management (six statements). Conclusions The consensus statements are a valuable reference resource for physicians managing patients with the alfapump® and for those considering management strategies for patients with refractory ascites.

Abstract
Ascites refers to the abnormal accumulation of fluid in the peritoneum resulting from an underlying pathology, such as metastatic cancer. Among all cancers, advanced-stage epithelial ovarian cancer is most frequently associated with the production of malignant ascites and is the leading cause of death from gynecologic malignancies. Despite decades of evidence showing that the accumulation of peritoneal fluid portends the poorest outcomes for cancer patients, the role of malignant ascites in promoting metastasis and therapy resistance remains poorly understood. This review summarizes the current understanding of malignant ascites, with a focus on ovarian cancer. The first section provides an overview of heterogeneity in ovarian cancer and the pathophysiology of malignant ascites. Next, analytical methods used to characterize the cellular and acellular components of malignant ascites, as well the role of these components in modulating cell biology, are discussed. The review then provides a perspective on the pressures and forces that tumors are subjected to in the presence of malignant ascites and the impact of physical stress on therapy resistance. Treatment options for malignant ascites, including surgical, pharmacological and photochemical interventions are then discussed to highlight challenges and opportunities at the interface of drug discovery, device development and physical sciences in oncology.

Tunnelled Peritoneal Catheter for Malignant Ascites-An Open-Label, Prospective, Observational Trial. Cancers (Basel) 2021; 13:cancers13122926. [PMID: 34208108 PMCID: PMC8230746 DOI: 10.3390/cancers13122926] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Revised: 06/01/2021] [Accepted: 06/08/2021] [Indexed: 02/06/2023] Open
Abstract
Treatment of recurrent malignant ascites in cancer patients is a challenge. Evidence based guidelines regarding the best treatment strategy are lacking. The aim of this prospective study was to investigate the safety and efficacy of a tunnelled peritoneal catheter (PleurX) in cancer patients with symptomatic ascites. Patients with symptomatic, diuretics-refractory ascites and indication for the implantation of a tunnelled peritoneal PleurX catheter were prospectively enrolled between August 2018 and July 2020. The number of catheter days, complications, amount of drained ascites and ascites-associated symptoms and hospitalization rate pre- and post-PleurX insertion were analysed. 51 Patients (64.7% male) were prospectively enrolled. The mean age was 66.6 (±7.9) years. The most common cause of ascites was pancreatic adenocarcinoma (n = 10) followed by cholangiocellular carcinoma (n = 9) and hepatocellular carcinoma (n = 8). The technical success rate of PleurX implantation was 100%. The mean volume of weakly drained ascites was 5.44l (±4.08). Major complications included cellulitis (n = 2), peritonitis and drainage dislocation (each n = 1). The mean catheter days per patient was 59.8 (±107.4) (Min 4, Max 668). Abdominal discomfort, impaired mobility, dyspnoea, fatigue, nausea and vomiting were significantly reduced 30 days after PleurX insertion (p < 0.05). Moreover, hospitalization rate was significantly reduced (p < 0.001; 27.08% of days preimplantation vs. 11.27% postimplantation). We conclude that implantation of a tunnelled ascites catheter is a safe and effective method for the treatment of refractory ascites in cancer patients with advanced disease. Serious complications are rare. Burdensome ascites-associated symptoms and hospitalization rates can be significantly reduced over a longer period of time.
