Abstract

Highlights: Cavernous transformation of the portal vein (CTPV) is rare. We presented a surgical case of gastric cancer with CTPV. Diseases causing intra-abdominal inflammation- may lead to CTPV. Patients with pancreatitis and choledocholithiasis must be assessed preoperatively for CTPV. Abstract: Introduction: There are few reported cases of cavernous transformation of the portal vein (CTPV). CTPV is usually found by accident because most patients are asymptomatic at presentation. This paper reports a case of early gastric cancer with CTPV that required gastrectomy and revascularization. Presentation of case: A 71-year-old man diagnosed with early gastric cancer, which was classified as clinical Stage IA (T1b, N0, M0) according to the TNM classification criteria for gastric cancer, was admitted to our hospital. Preoperative computed tomography (CT) revealed portal vein stenosis, CTPV, and esophageal varix. CT angiography showed that portal flow was maintained by the left gastric vein-right gastric vein (LGV-RGV) shunt. We had to perform lymphadenectomy while maintaining the hepatic blood flow. We performed distal gastrectomy with lymph node dissection including the vessel of the lesser curvature without massive bleeding. Postoperative course was uneventful, and CT examination performed in the 7th postoperative day revealed good blood flow from the reconstructed collateral vessels. The patient had no recurrence of gastric cancer during the postoperative period of 1 year. Conclusion: Diseases that cause intra-abdominal inflammation, such as pancreatitis and choledocholithiasis, might cause CTPV. Thus, patients with this medical history should be carefully assessed for CTPV to avoid intraoperative complications, such as massive bleeding or ischemia. When we preform operation a case with CTPV, we must pay meticulous attention. In our case, we encountered some difficulties in the surgical procedure, especially with respect to the dissection of the regional lymph nodes for gastric cancer.
