Risk of hernia incarceration following transjugular intrahepatic portosystemic shunt placement

Hernia complications after creation of a transjugular intrahepatic portosystemic shunt (TIPS) have been reported, although the incidence of this complication is unknown. This study was designed to determine the incidence, morbidity, and outcome of hernia complications in patients with preexisting abdominal or inguinal hernias after TIPS creation.

The medical records of 244 consecutive patients undergoing TIPS creation between 1999 and 2007 at a single institution were reviewed. The study population was 57 patients (23%) with a preprocedural abdominal or inguinal hernia. The investigated outcome was small bowel obstruction or postprocedural incarceration of a preexisting hernia. Demographic and procedural variables were evaluated for an associated increased risk of hernia complications.

Hernia complications developed in 25% of patients (14 of 57) after TIPS creation at a mean presentation of 62 days (range, 2-588 d). Thirteen complications (93%) required emergent surgery, of which four (29%) required bowel resection for necrosis. There were no resulting deaths. Ninety-eight percent of patients with a hernia complication had the procedure to treat refractory ascites. The indication of refractory ascites was significantly associated with the risk of a hernia complication (P = .002).

A 25% incidence of hernia complications following TIPS creation in patients being treated for refractory ascites is higher than expected; emergent surgery is required in most cases. Further investigation to formulate a plan for elective management is warranted.
