Partial major hepatectomy with cyst fenestration for polycystic liver disease: Indications, short and long-term outcomes.

Background And Objective: Symptomatic polycystic liver disease (PLD) with massive hepatomegaly represents a challenging surgical issue. In this work, we focused on early and long term outcomes after partial hepatectomy with cyst fenestration (PHCF) in selected patients.

Methods: All patients who had PHCF for treatment of PLD between January 2003 and December 2019 in our center were included in this study. PHCF was undertaken if at least one hepatic section was relatively spared from PLD, afferent and efferent hepatic vasculature was patent, and liver function was maintained.

Results: Twenty nine patients (25 women) with a mean age of 54.6 ± 9 years underwent PHCF. Major hepatectomy was performed in all cases with 4.3 ± 0.8 resected segments. Overall perioperative morbidity (Clavien ≥ II) and mortality rates were 41.4.6% and 13.8% respectively. Significant postoperative liver volume reduction was 52.8% within the first year and 55.5% thereafter. From preoperative evaluation, performance status (PS) normalized or improved in 84% of patients. After a mean follow-up time of 70.8 ± 65 months, overall patient survival was 82.7%. In univariate analysis, PS, initial liver volume, operative time and transfusion were associated with post-operative complications and PS, preoperative cyst infection, portal hypertension, transfusion, postoperative sepsis and persistent ascites were associated with mortality.

Conclusions: Our study confirms that in spite of significant morbidity rate, PHCF allows a massive reduction of liver volume in selected patients with symptomatic PLD and is highly and durably effective for the reduction of liver volume and improvement of quality of life.
