Now, most TIPS are created with polytetrafluoroethylene (PTFE)-covered stent-grafts. Our study investigates the impact of distance from the HCJ on long-term patency of PTFE-covered TIPS. Methods PTFE-covered TIPS placed between 2002 and 2013 were retrospectively reviewed. selleck inhibitor Clinical and imaging data were collected from the electronic medical record and radiology imaging archive. Distance from HV end to the HCJ was recorded. Primary patency rates were calculated. Differences between groups based on distance

from HV end to HCJ were compared using Kaplan-Meier and Cox regression analyses. Results 300 PTFE-covered TIPS were included in the study. 201 were placed with a single stent-graft while 99 were extended at the HV end with additional BMS(N=70) or stent-grafts(N=29). No threshold distance between HV end of the TIPS and HCJ was found to impact long-term patency (p-values at thresholds of 0, 5,

10, 15, and 20 mm were 0.92, 0.79, 0.43, 0.36 and 0.24 respectively). Primary patency in TIPS placed with just a single stent-graft versus those using additional stents was 90% vs 82%, 83% vs 71%, 81% vs 60% 6 months, 1 and 2 years respectively (p = 0.03). In TIPS created with multiple stents, primary patency of those with BMS versus PTFE-covered extensions was 84% vs 78%, 73% vs 69%, and 69% vs 46% at 6 months, 1 and 2 years respectively (p = 0.28). Regression analysis demonstrated the length by which a TIPS was extended and

the final distance of the HV end to the Baf-A1 molecular weight HCJ were not predictors of patency failure (p>0.1 and p find more = 0.06 respectively). Conclusion If the HV end of PTFE-covered TIPS is within 2 cm of the HCJ, the primary patency is not determined by the actual distance from the HCJ nor is it improved by extending the TIPS to the HCJ. If extended, PTFE-covered extensions offer no patency benefit over BMS. The best patency rates occur with single PTFE-covered TIPS.

Soulen Background and Aims: – Spontaneous bacterial peritonitis (SBP) is the commonest and life-threatening infection in liver cirrhosis. Identification of risk factors, choice and timing of antibiotic in relation to response can improve outcome.We investigated the role of serial ascitic tap for antibiotic response to predict the outcome. Patients and Methods: – Patients of decompensated cirrhosis diagnosed with spontaneous bacterial peritonitis (as per definition) were analyzed retrospectively. As per protocol, the patient underwent ascitic tap after 48hr in all cases and on 5th and 7th day depending upon the clinical parameters. Results:- Total 161 patient of decompensated cirrhosis, mean age 50.8yrs(±11.8SD, ) 82% male, with mean CTP =12.3±1.47 and median MELD = 22.7 (range=16-28) were analyzed.
