- Study population - Cirrhotic patients with recurrent hepatic hydrothorax
- Study design - A prospective, randomized, single center open label study
- Block Randomization, block size - 10
- Sample size - Assuming in single time thoracocentesis group 5+/-3.67 thoracocentesis is required, investigator expect a 50 % reduction in pigtail drainage group. Apha error- 5, power -90, 15% dropout 35 patients in each arm
- Intervention - Group 1 - on-demand therapeutic thoracocentensis, Group 2 - small volume frequent thoracocentesis using PCD.
- Monitoring and assessment
- At enrollment:
(A) Complete history and examination
- Etiology of cirrhosis
- Severity of ascites, Jaundice
- Prior Hepatic encephalopathy, bleed, Jaundice
- Prior Spontaneous bacterial peritonitis, large volume paracentesis frequency
- Pattern and number of prior decompensation
- Prior Acute on Chronic Liver Failure and Acute Kidney episodes
- Use of non selective beta blockers, norfloxaxin, rifaximin and albumin
- History of Endoscopic Variceal ligation or other endotherapy
- History of Hypertension, Diabetes
- Fever , signs of sepsis (SIRS)
- Examination- Sarcopenia, fraility, icterus, pedal edema
At follow-up (at daily till Day - 7, thereafter at Day - 30 and Day 90) Complete history and examination
- Complications - SBP, SBE, ACLF and Jaundice, HE/ AKI episodes
- HTN, Diabetes control
- Fever , signs of sepsis (SIRS)
- Examination- Sarcopenia, fraility, icterus, pedal edema, ascites, HE Clinical Evaluation

STATISTICAL ANALYSIS -
- Data will be reported as mean + SD.
- Categorical variables will be compared using the chi-square test or Fisher exact test
- Normal continuous variables will be compared using the Student's t test
- Non normal continuous variables will be compared using the Mann-Whitney rank-sum test (unpaired data) or the Wilcoxon test (paired data).
- The actuarial probability of survival will be calculated by the Kaplan-Meier method and compared using the log-rank test.
- A Cox regression analysis will be performed to identify independent prognostic factors for survival.
- Univariate and multivariate analysis will be used whenever applicable.
-
Adverse effects - Chest pain, pain at the site, Breathlessness, infection, pneumothorax, infection, bleeding
-
Stopping rule -
- Liver Transplant
- Appearance of SBP, PICD, HE.
- Mortality
- End of follow-up
