Background & Aims:

In patients with noncirrhotic chronic extra-hepatic portal vein obstruction (EHPVO), data on morbimortality of abdominal surgery are scarce.

Approach & Results:

We retrospectively analyzed the charts of 76 patients (78 interventions) with EHPVO undergoing abdominal surgery within the VALDIG network. Fourteen percent of the patients had ≥1 major bleeding (unrelated to portal hypertension) and 21% had ≥1 Dindo-Clavien grade ≥3 postoperative complication within 1 month after surgery. Fifteen percent had ≥1 portal hypertension related complication within 3 months after surgery. Three patients died within 12 months after surgery. An unfavorable outcome (i.e. ≥1 above-mentioned complications or death) occurred in 37% of the patients and was associated with a history of ascites and with non-wall, non-cholecystectomy surgical intervention: 17% of the patients with none of these features had an unfavorable outcome, versus 48% and 100% when one or both features were present, respectively. We then compared 63/76 EHPVO patients with 126 matched (2:1) control patients without EHPVO but with similar surgical interventions. As compared with control patients, incidence of major bleeding (p<0.001) and portal-hypertension related complication (p<0.001) was significantly higher in patients with EHPVO, but not that of grade ≥3 postoperative complication nor of death. The incidence of unfavorable post-operative outcome was significantly higher in patients with EHPVO than in those without (33% vs. 18%, p=0.01).

Conclusion:

Patients with EHPVO are at high-risk of major peri- or postoperative bleeding and postoperative complications, especially in those with ascites or undergoing surgery other than wall surgery or cholecystectomy.
