Purpose:
This study was performed to compare the intrahepatic shunt function outcome and procedural complications of minilaparotomy-assisted transmesenteric (MAT)-transjugular intrahepatic portosystemic shunt (TIPS) placement with the conventional transjugular method.
Methods:
This is a retrospective review of all patients who had a MAT or conventional TIPS procedure over a 6-year period at our institute. The primary patency rate, fluoroscopy time, technical success, major procedure-related complications, and mortality data were compared between two treatment groups.
Results:
We included 49 patients with MAT-TIPS, and 63 with conventional TIPS, with an average follow-up of 21.43 months. The primary patency rates at 6 and 12 months were 82.9 and 66.7 % in the conventional TIPS group, and 81.0 and 76.5 % in the MAT-TIPS group (p = 1.000, and 0.529), respectively. There was no significant difference in technical success rate, post-procedure portosystemic pressure gradient, fluoroscopy time, and peri-procedural mortality rate between treatment groups. Major procedural-related complications were seen more frequently among MAT-TIPS patients (p = 0.012). In the MAT-TIPS group, 5 (10.2 %) patients developed post-procedure minilaparotomy, wound-related complications, and 5 (10.2 %) developed bacterial peritonitis; whereas, none of patients with conventional TIPS had either of these complications (p = 0.014).
Conclusion:
While both MAT-TIPS and conventional TIPS had similar shunt primary patency rate and technical success rate, the MAT approach was associated with a significantly higher rate of minilaparotomy-related wound complications or infectious complications. These complications maybe prevented by a change in post-procedure monitoring and therapy.
