title: Total Laparoscopic Reversal ALPPS.
abstract: BACKGROUND
  Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows R0 resection even for patients with extremely small future liver remnants. The ALPPS procedure was initially described for two-stage right trisectionectomy. Reversal ALPPS is a denomination in which the future liver remnant is the right posterior section of the liver.
  
  
  METHODS
  A 42-year-old woman with colorectal metastases in all segments except segment 1 underwent chemotherapy with objective response and was referred for surgical treatment. The computed tomography (CT) scan showed a predominance of metastases in the left liver and in the right anterior section. The right posterior section had three metastases. The plan was to perform a laparoscopic reversal ALPPS (left portal vein ligation combined with in situ splitting in a two-stage left trisectionectomy).
  
  
  METHODS
  Three metastases in the right posterior section were resected, followed by liver partition and left portal vein ligature. The CT scan showed a 70 % increase in the future liver remnant. The second stage constituted left trisectionectomy. At laparoscopy after division of adhesions, the left Glissonian pedicle was divided with an endostapler. A stapler also was used to transect the left and middle hepatic veins, and the specimen was removed through a suprapubic incision. The operative times were respectively 5 and 3 h, and the patient was discharged on days 4 and 5, respectively. No blood transfusion or intensive care unit stay was necessary. At this writing, the patient shows no evidence of the disease 18 months after the procedure.
  
  
  CONCLUSIONS
  Reversal laparoscopic ALPPS is feasible and safe. Laparoscopy is useful for decreasing blood loss and optimizing visualization during liver transection.
