For individuals who are intolerant to medical therapy and require frequent large-volume paracentesis, a peritoneovenous shunt (PVS) offers a potential treatment option. However, PVS placement is associated with high complication rates, perioperative mortality, and lacks well-defined indications.<\/jats:p>\n                  <jats:p>AIM<\/jats:p>\n                  <jats:p>To identify prognostic factors for PVS placement and develop a novel postoperative survival scoring model for LC with refractory ascites.<\/jats:p>\n                  <jats:p>METHODS<\/jats:p>\n                  <jats:p>A total of 100 patients who underwent PVS placement for refractory ascites due to LC in our department between 1998 and 2024 were analyzed. Patients were stratified into two groups: Those who survived more than 180 days after PVS placement (L-group) and those who survived for less than 180 days (S-group). Prognostic factors were compared between groups, and four variables (sex, age, Child-Pugh score, and liver volume) were selected for the creation of a new scoring system.<\/jats:p>\n                  <jats:p>RESULTS<\/jats:p>\n                  <jats:p>Significant differences between the S- and L-groups were observed for age, sex, Child-Pugh score and preoperative liver volume. Based on these variables, we developed a scoring system as follows: 1 point each for age \u2265 60 years, Child-Pugh score \u2265 10, female sex, and preoperative liver volume &lt; 1057 mL. Patients scoring 0-2 points were classified as PVS grade A, and those scoring 3-4 points as PVS grade B. Survival analysis showed that overall survival was significantly higher in PVS grade A compared with PVS grade B. Multivariate analysis confirmed PVS grade as an independent prognostic factor.<\/jats:p>\n                  <jats:p>CONCLUSION<\/jats:p>\n                  <jats:p>The proposed PVS scoring system may be a useful tool for predicting postoperative prognosis following PVS placement in patients with LC and refractory ascites.<\/jats:p>","DOI":"10.3748\/wjg.v31.i45.113848","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T06:32:41Z","timestamp":1764743561000},"source":"Crossref","is-referenced-by-count":0,"title":["Prognostic
