Applying negative pressure wound therapy in associating liver partition and portal vein ligation for staged hepatectomy: A case report.

Staged hepatectomy, particularly associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a recently developed advanced surgery for resecting liver tumors. However, large wound surfaces, incomplete drainage and high rates of mortality are vital limitations of ALPPS. The present case study describes a patient with liver cancer who underwent ALPPS surgery combined with negative pressure wound therapy. A 46-year-old male patient was hospitalized due to right upper abdominal pain. Computed tomography and magnetic resonance cholangiopancreatography scan results indicated gallbladder cancer, accompanied by multiple liver metastases. Resection of the right trisegment and partial resection of metastatic nodules in the left outer lobe were performed. Vacuum sealing drainage was pre-implanted at liver cross-sections with drainage tubes to drain the bile. The patient exhibited improved wound healing compared with conventional ALPPS.
