title: Cavernous transformation of the portal vein coinciding with early gastric cancer and cholelithiasis.
abstract: A 71-year-old man who developed jaundice with a high-grade fever was admitted to our hospital. The episode was ascribed to cholecysto-choledocholithiasis. In the preoperative evaluation, a cavernous transformation of the portal vein and an early gastric cancer were found. The patient thereafter underwent an operation for those pathologies after the endoscopic removal of a choledochal stone; cholecystectomy, and a distal gastrectomy with regional lymph node dissection for gastric cancer. The proposed procedures of gastrectomy and cholecystectomy were completed without any major difficulty because no markedly enlarged collateral veins were found in the area where the regional lymph node dissection was carried out. Thanks to advances in imaging modalities, an asymptomatic cavernous transformation of the portal vein coinciding with gastric cancer such as that seen in the present case may be increasingly encountered in the future. The greatest caution, however, needs to be exerted at operation to minimize any unexpected bleeding and to avoid any interruption of the porto-portal shunts in such cases. Further, the reestablishment of the portal blood supply to the liver might be required in advanced cases of gastric cancer, where regional lymph node dissection may necessitate skeletonization of the hepatoduodenal ligament for curative purposes.
