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

Abstract

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. A left "ex-situ in-vivo" hepatectomy was performed by dissecting and ligating the left and middle hepatic veins, clamping and sectioning the right hepatic vein, Pringle maneuver, externalization of the liver followed by the tumor resection and right hepatic vein reimplantation. The short warm ischemia time (hepatic resection + liver reimplantation - 30 minutes) allowed us to perform the procedure without installing a veno-venous or porto-caval shunt otherwise used in all of ex-situ procedures described in the literature reviewed in this presentation. Ex-situ liver resection is a viable procedure for giant liver tumours in highly selected cases. It facilitates resection of large liver tumours that would be otherwise unresectable, extending the indications of surgical treatment.

Prognostic Analysis of Distal Pancreatectomy for Pancreatic Body and/or Tail Cancer Involving the Portal Vein

“…There have been no previous reports on the surgical outcome and long-term survival of patients who underwent DP or DP-CAR for PbtCa involving PV, except for case reports 19 . This is the first report to demonstrate the prognostic impact of DP or DP-CAR for PbtCa with PV contact.…”

Pancreaticoduodenectomy For Complex Pancreaticoduodenal Trauma: A Case Series

“…Pancreaticoduodenectomy in trauma patients presents the risk of leakage following anastomosis due to a soft pancreatic stump, or a non dilated and narrow main pancreatic duct. 7 The most important influencing factors leak or fistula formation are the presence of a soft texture within the pancreatic remnant and a small Duct of Wirsung which complicates the achievement of a safe pancreatico-enteric anastomosis. This is a frequent event in cases of non-obstructive problems such as trauma.…”
