Abstract

BACKGROUNDS/AIMS
Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) has generated controversy due to high morbidity and mortality. We present our series of patients with 30-40% parenchymal transection and minimal hilar dissection.
METHODS
Patients who had partial ALPPS between April 2015 and April 2016 were included. Patients with colorectal liver metastases (CRLM) had their future liver remnants (FLR) cleared with metastasectomies. The liver was divided along the future line of transection to 30-40%, right portal vein was stapled and divided without extensive hilar dissection, with minimal handling of right liver, which was not mobilised. We preserved the middle hepatic vein. Data were collected prospectively for hypertrophy of the FLR, morbidity and mortality.
RESULTS
Among the 8 patients (age 25-68) investigated, one patient with cholangiocarcinoma had portal vein embolization prior to partial ALPPS. All patients completed two stages with adequate FLR hypertrophy at a median of 28 days. No mortality was found. The median length of stay after stages 1 and 2 was 9 and 9.6 days, respectively. The median increase in FLR was 38%.
CONCLUSIONS
A limited transection of 30-40%, minimal hilar dissection and longer wait between stages yielded adequate FLR hypertrophy with low morbidity and no mortality.
