Objective: To evaluate hemodynamics by arteriographic examinations with and without CT in the stomach wall and liver after preoperative embolization to redistribute blood flow to the stomach and liver, which is unified to be supplied from the superior mesenteric artery, before distal pancreatectomy with en bloc celiac axis resection (DP-CAR).
Material And Methods: In six patients with locally advanced cancer of the pancreatic body in whom DP-CAR was planned, the left gastric artery and common hepatic artery were embolized with coils. Celiac arteriography and superior mesenteric arteriography with and without CT were performed after embolization.
Results: In all six patients, intrahepatic arteries and the left gastric artery were not visualized on celiac arteriography. On both superior mesenteric arteriography and CT obtained while contrast medium was infused via the superior mesenteric artery and which was performed immediately after embolization procedures, the right gastric artery, gastroepiploic artery, gastroduodenal artery, and all hepatic arterial branches were clearly detected. Also the distal part of the left gastric artery close to the embolized point was detected with at least one of the imaging modalities.
Conclusion: It was clarified radiologically that preoperative embolization results in increased blood supply to the stomach wall and liver through the pancreatic arcade.

Background: Splanchnic vein thrombosis (SpVT) occurs in 17%-23 % of acute pancreatitis cases. Serious sequelae include hepatic and bowel ischaemia. However, management with therapeutic anticoagulation remains controversial due to potential bleeding risk.

Background: Lymph node dissection is required for many pancreatic neuroendocrine neoplasms. However, the need for such dissection has rarely been examined in detail by the tumor size, tumor location, or World Health Organization grading. The objective is to determine which characteristics of pancreatic neuroendocrine neoplasms require lymph node dissection, and to what extent lymph node dissection should be performed.

In hepatic flexure and transverse colon cancer surgeries, mobilizing the right mesocolon and precisely dissecting the gastrocolic trunk of Henle (GTH) are crucial. Previous classifications of GTH tributaries do not guide radical right hemicolectomy due to post-procedural anatomical acquisition. This study analyzed vessel associations, including the middle colic vein (MCV) converging site, right colic artery (RCA) presence, and other GTH tributaries, using ultra-thin CT for reconstruction.

Major vessel invasion, particularly involving the portal and superior mesenteric veins, poses significant challenges during the radical resection of hepatobiliary and pancreatic cancers. Oncovascular surgery is essential for curative outcomes, and often requires portomesenteric vein reconstruction. Techniques, such as lateral venorrhaphy, patch repair, end-to-end anastomosis, and interposition grafting, have been employed.

Background: Intestinal ischemiareperfusion (I/R) injury (II/RI) is a critical condition that results in oxidative stress, inflammation, and damage to multiple organs. Zinc, an essential trace element, offers protective benefits in several tissues during I/R injury, but its effects on intestinal II/RI remain unclear.
Aim: To investigate the effects of zinc pretreatment on II/RI and associated multiorgan damage.
