GOOD TO KNOW: The ALPPS Procedure - Embracing a New Technique.

Chirurgia (Bucur) 2017 May-Jun;112(3):332-341

Background: Hepatic resection is the only potentially curative treatment for primary liver tumors and hepatic metastases. The most frightening postoperative complication of extensive hepatectomies is liver failure due to insufficient future liver remnant (FLR). The ALPPS technique (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) effectively increased the resectability of otherwise inoperable liver tumors (primary or secondary malignant liver tumor) by achieving a rapid and an effective hypertrophy of the FLR, which lowers postoperative liver failure risk.

Ante-situm Liver Resection for Giant Hepatic Tumour - Case Report and Review of Literature.

Chirurgia (Bucur) 2017 May-Jun;112(3):326-331

Ex-situ liver surgery refers to complex liver resections involving hepatic vascular exclusion and a warm ischemia time (WIT) of more than 90 minutes that allows liver resection and vascular reconstruction in patients with giant liver tumours with a difficult approach . Ante-situm liver resections, otherwise called "œex-situ in-vivo" resections is achieved through externalization of the liver outside of the abdominal cavity by clamping and sectioning of the efferent pedicles (suprahepatic veins) ("ex situ") without cutting the afferent vascular pedicle ("in vivo"), thus leaving the hepatic pedicle intact. We present a case report of a 36 yo male patient diagnosed by MRI scan with giant liver tumor in the left hemiliver. Read More

Approach to hepatocaval confluence during laparoscopic right hepatectomy: three variations on a theme.

Surg Endosc 2017 02 20;31(2):949. Epub 2016 Jun 20.

Hepatobiliary Surgery Division, IRCCS San Raffaele Hospital, Via Olgettina 60, 20132, Milan, Italy.

Introduction: Due to technical challenges and reduced pool of candidates, laparoscopic major hepatectomies remain relatively limited: In particular, right hepatectomy is technically more challenging than left since it requires liver mobilization, dissection of inferior vena cava (IVC) and hepatocaval confluence (HepCC), and section of right hepatic vein (RHV).

Materials And Methods: Among 53 laparoscopic right hepatectomies (San Raffaele Hospital; 2013-2015), the approach to HepCC was standardized by three techniques: (1) primary approach to IVC and RHV with complete mobilization of right hemiliver; (2) anterior approach with hanging maneuver without liver mobilization (partial anterior approach-PAA); and (3) anterior approach without hanging maneuver without liver mobilization of right hemiliver (total anterior approach-TAA). The technique was defined preoperatively based on tumor size/position, IVC/RHV compression, and HepCC dislodgement. Read More

Outcomes of Full-Right-Full-Left Split Liver Transplantation in Adults in the USA: A Propensity-Score Matched Analysis.

Int J Organ Transplant Med 2016 1;7(2):69-76. Epub 2016 May 1.

Division of Organ Transplantation, Department of Surgery, Alpert Medical School of Brown University, Providence, RI, USA.

Background: Splitting a liver for utilization in adult/pediatric recipients has been shown to decrease mortality on the wait list without increasing the overall risk of long-term graft failure compared to a whole graft. However, splitting a single donor organ for two adult recipients, full-right-full-left split liver transplantation (FRFLSLT), to overcome organ shortage is still considered controversial.

Objective: This study assessed the outcome of FRFLSLT comparing full-right (FR) and full-left (FL) with whole liver (WL) allografts in adults (1998-2010) using UNOS standard transplant analysis and research (STAR) file. Read More
