Parenchyma-preserving hepatectomy based on portal ramification and perfusion of the right anterior section: preserving the ventral or dorsal area

Anatomical hepatectomy aims to eliminate the spread of malignant tumor cells via portal vein systemically. An anatomical concept of the right anterior section (RAS) and preservation of the liver parenchyma within the RAS has been proposed.

Interferon γ and plasminogen activator inhibitor 1 regulate adhesion formation after partial hepatectomy

The pathophysiology of intra‐abdominal adhesions has not been studied extensively. The aim of this study was to elucidate the molecular mechanisms underlying adhesion formation in a murine model and in patients undergoing hepatectomy.

Salvage treatment of laparoscopic cholecystectomy‐associated bile duct stenosis combining laparoscopic and endoscopic procedures: A case report

The incidence of laparoscopic cholecystectomy (LC)‐associated bile duct injury has reached a steady state despite learning curve effect. Herein we report the case of a 74‐year‐old Japanese man who suffered from bile duct stenosis and stones after LC. The stenosis was due to stricture caused by surgical clips used inappropriately during LC. We planned a salvage treatment combining laparoscopic and endoscopic approaches. At laparoscopic observation, the clips had already invaded the right side of the bile duct; minimal absorbable suture was performed after all the clips were removed. The bile duct stenosis was then endoscopically dilated and the biliary stones were successfully removed. For the recurrent biliary stenosis after discharge, endoscopic balloon dilation was performed and multiple plastic stent tubes were placed. The stent tubes were removed 4 months later, and the patient has had no symptoms for 1 year. A combined laparoscopic and endoscopic approach was useful for the salvage treatment of LC‐associated bile duct stenosis.
