Due to different disease background of gastric stump cancer(GSC) patients (benign or malignant lesion, reconstruction of digestive tract, etc.), the GSC surgical procedure and the difficulty of lymphadenectomy are also different. The extent of radical lymphadenectomy for gastric stump cancer should extend beyond D2 lymphadenectomy, according to the different backgrounds of initial disease, reconstructions, and tumor location. A lymphadenectomy should include the lymph nodes in anterior (No.17) and posterior (No...

We present the unique case of a 15-month-old male born with biliary atresia and situs inversus totalis and disrupted inferior vena cava who underwent a successful liver transplantation. The patient had previously undergone a failed Kasai procedure and presented with persistent hyperbilirubinemia. The patient was transplanted with a left lateral segment donor having standard arterial anatomy. Technical considerations included identifying completely replaced arterial anatomy in the recipient from the superior mesenteric artery and creating a branch patch between the gastroduodenal artery and HA, anastomosing the donor left hepatic vein to confluences of the donor left, middle, and right hepatic veins, using a "lazy-S" configuration of portal vein anastomosis, and suspending the allograft to the abdominal wall...

AIM: To investigate viability assessment of segmental small bowel ischemia/reperfusion in a porcine model. METHODS: In 15 pigs, five or six 30-cm segments of jejunum were simultaneously made ischemic by clamping the mesenteric arteries and veins for 1 to 16 h. Reperfusion was initiated after different intervals of ischemia (1-8 h) and subsequently monitored for 5-15 h. The intestinal segments were regularly photographed and assessed visually and by palpation. Intraluminal lactate and glycerol concentrations were measured by microdialysis, and samples were collected for light microscopy and transmission electron microscopy...

Malrotation of the gut is a common paediatric condition that usually presents in the first month of life. However, presentation in adults is rare, and as a diagnostic dilemma quite often surprises the surgeon intraoperatively. If this condition is not timely recognized, it may result in disastrous consequences, such as gangrene of the small gut. We present the case of a 21-year-old male who presented to the emergency room with recurrent episodes of colicky abdominal pain and bilious vomiting. Contrast-enhanced computerized tomography (CT) revealed malrotation of the gut...

Castleman disease is a lymphoproliferative disorder with unknown etiology and pathogenesis. While the disease may involve all parts of the body, the mediastinum appears to be the most common part of involvement. In this study, we present two cases of Castleman disease with different localizations that mimicked malignancy. A 62-year-old female patient presented with jaundice. Laboratory analysis indicated aspartate aminotransferase: 250 U/L, total bilirubin: 4 mg/dl, and carbohydrate antigen (CA) 19-9: 900 U/ml...

BACKGROUND: Accurate prediction of mesenteric venous involvement in pancreatic ductal adenocarcinoma (PDAC) is necessary for adequate staging and treatment. METHODS: A retrospective cohort study was conducted in PDAC patients at a single institution. All patients with resected PDAC and staging CT and EUS between 2003 and 2014 were included and sub-divided into "upfront resected" and "neoadjuvant chemotherapy (NAC)" groups. Independent imaging re-review was correlated to venous resection and venous invasion...

BACKGROUND: Acute pancreatitis may cause massive intra-abdominal bleeding as vascular complications caused by the erosion of a major pancreatic or peripancreatic vessel. In terms of treatment, the differentiation between arterial bleeding and venous bleeding using abdominal computed tomography (CT) angiography is important. In addition, hypovolemic shock caused by bleeding from the inferior mesenteric vein (IMV) in acute pancreatitis has not been reported. CASE REPORT: A 58-year-old man presented to our emergency department with complaints of abdominal pain of 10 hours' duration...

We explored the relationship between abdominal vein thromboses, including portal vein thrombosis (PVT) and superior mesenteric vein thrombosis (SMVT), and thrombophilia. The frequency of thrombophilia, such as antithrombin (AT), protein C (PC), or protein S (PS) gene mutations, was examined in 21 patients with PVT, 6 patients with SMVT, and 6 patients with both PVT and SMVT. Low levels of AT, PC, or PS were frequently detected in patients with PVT or mesenteric vein thrombosis, and 4 mutations in the PS gene, 3 mutations in the PC gene, and 2 mutations in AT the gene were detected...

Nutcracker syndrome (NS) refers to symptomatic compression of the left renal vein (LRV) between the abdominal aorta and superior mesenteric artery with potential symptoms including hematuria, proteinuria, left flank pain, and renal venous hypertension. No consensus diagnostic criteria exist to guide endovascular treatment. We aimed to evaluate the specificity of LRV compression to NS symptoms through a retrospective study including 33 NS and 103 control patients. The size of the patent lumen at point of compression and normal portions of the LRV were measured for all patients...

OBJECTIVE: The middle hepatic vein reconstruction is one of the crucial parts in adult living donor liver transplantation. Numerous techniques had been reported by using cadaveric iliac vessel or synthetic graft. The limitations of reported techniques are availability of the vessel and complication of synthetic graft. We report the technique of using explanted portal vein and inferior mesenteric vein graft in sequential fashion. PATIENTS AND METHODS: The recipient was a 54-year-old man with chronic hepatitis B cirrhosis and multiple hepatocellular carcinomas...

A 44-year-old man with cirrhosis arising from alcohol abuse manifested melena caused by the rupture of esophageal varices. He received endoscopic variceal ligation for the initial hemostasis, followed by endoscopic injection sclerotherapy as an additional consolidation therapy. A CT examination performed at the time of admission revealed collateral veins developing around the ascending colon, in which the feeding and draining vessels were identified as the superior mesenteric vein and the right testicular vein, respectively...

Background: Isolated superior mesenteric vein (SMV) thrombosis is a rare but potentially fatal condition if untreated. Current treatments include transjugular or transhepatic approaches for rheolytic mechanical thrombectomy and subsequent infusions of thrombolytics. Tissue plasminogen activator (t-PA) power-pulse spray can provide benefit in a single setting without thrombolytic infusions. Computed tomography (CT) guidance for portal vein access is underutilized in this setting. Materials and Methods: Case 1 discusses acute SMV thrombosis treated with rheolytic mechanical thrombectomy alone using ultrasound guidance for portal vein access...

Hematochezia is a rare clinical presentation of congenital extrahepatic portosystemic shunt (CEPS). We describe a series of three patients with type II CEPS presenting as hematochezia that were treated by catheter embolization, followed by a brief review of published articles. Hematochezia of the patients was due to the giant inferior mesenteric vein, superior rectal vein and colonic varices. The catheter embolization was successfully accomplished in all of the patients. After a mean follow-up of 27 months, no serious adverse effects were observed...

Non-functional pancreatic neuroendocrine tumours (NETs) can present with advanced local or distant (metastatic) disease limiting the possibility of surgical cure. Several treatment options have been used in experimental neoadjuvant settings to improve the outcomes in such cases. Peptide receptor radionuclide therapy (PPRT) using beta emitting radiolabelled somatostatin analogues has been used in progressive pancreatic NETs. We report a 55-year-old female patient with a 12.8 cm pancreatic NET with significant local stomach and superior mesenteric vein compression and liver metastases...

Blood flow changes in cranial abdominal vessels are important contributing factors for canine hepatic disease. This prospective, experimental, pilot study aimed to evaluate cardiac-gated, phase contrast magnetic resonance angiography (PCMRA) as a method for characterizing blood flow in canine major cranial abdominal vessels. Eleven, healthy, adult beagle dogs were sampled. Cardiac-gated, phase contrast magnetic resonance angiography of the cranial abdomen was performed in each dog and blood flow was independently measured in each of the major cranial abdominal vessels by three observers, with two observers recording blood flow values once and one observer recording blood flow values three times...
