Original Study: Transjugular Intrahepatic Portosystemic Shunt as a Bridge to Abdominal Surgery in Cirrhotic Patients

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) has been suggested to reduce portal hypertension-associated complications in cirrhotic patients undergoing abdominal surgery. The aim of this study was to compare postoperative outcome in cirrhotic patients with and without specific preoperative TIPS placement, following elective extrahepatic abdominal surgery.

METHODS

Patients were retrospectively included from 2005 to 2016 in four centers. Patients who underwent preoperative TIPS (n = 66) were compared to cirrhotic control patients without TIPS (n = 68). Postoperative outcome was analyzed using propensity score with inverse probability of treatment weighting analysis.

RESULTS

Overall, colorectal surgery accounted for 54% of all surgical procedure. TIPS patients had a higher initial Child-Pugh score (6[5-12] vs. 6[5-9], p = 0.043) and received more beta-blockers (65% vs. 22%, p < 0.001). In TIPS group, 56 (85%) patients managed to undergo planned surgery. Preoperative TIPS was associated with less postoperative ascites (hazard ratio = 0.330 [0.140-0.780]). Severe postoperative complications (Clavien-Dindo > 2) and 90-day mortality were similar between TIPS and no-TIPS groups (18% vs. 23%, p = 0.392, and 7.5% vs. 7.8%, p = 0.644, respectively).

CONCLUSIONS

Preoperative TIPS placement yielded an 85% operability rate with satisfying postoperative outcomes. No significant differences were found between TIPS and no-TIPS groups in terms of severe postoperative complications and mortality, although TIPS patients probably had worse initial portal hypertension.
