Years ago, we revealed a novel cytoprotective mediator, stable gastric pentadecapeptide BPC 157, particular anti-ulcer peptide that heals different organs lesions when given as a therapy, native in human gastric juice while maintaining GI- tract mucosal integrity, already tested in trials (ulcerative colitis and now multiple sclerosis). The stomach cytoprotection is the most fundamental concept, stomach cell protection and endothelium protection are largely elaborated, but so far cell, protection and endothelium protection outside of the stomach were not implemented in the therapy...

BACKGROUND: Pancreatic body and tail ductal adenocarcinomas are often diagnosed with local vascular invasion of the celiac axis (CA) and its various branches. With such involvement, these tumors have traditionally been considered unresectable. The modified Appleby procedure allows for margin negative resection of some such locally advanced tumors. This procedure involves distal pancreatectomy with en bloc splenectomy and CA resection and relies on the presence of collateral arterial circulation via an intact pancreaticoduodenal arcade and the gastroduodenal artery to maintain prograde hepatic arterial perfusion...

The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography (CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case...

Described are certain clinical and morphologic features of one patient with acute, another with subacute, and one with chronic cor pulmonale. All 3 had evidence of severe pulmonary hypertension. The patient with acute cor pulmonale 4 days after coronary bypass for unstable angina pectoris suddenly developed severe breathlessness with cyanosis and had fatal cardiac arrest and necropsy disclosed massive pulmonary embolism. The patient with subacute cor pulmonale had severe right-sided heart failure for 5 weeks and necropsy disclosed microscopic-sized neoplastic pulmonary emboli from a gastric carcinoma without parenchymal pulmonary metastases...

Type 2 diabetes mellitus (T2DM) is a prevalent disease worldwide and during its conventional treatment, vascular complications remain unavoidable. Roux-en-Y gastric bypass (GBP) is able to induce the remission of T2DM. However, studies of duodenal-jejunal bypass (DJB), a modified procedure of GBP, are being carried out to investigate its ability to induce the remission of T2DM and protect the aorta from atherosclerosis. The present study aimed to investigate the effect of DJB on the rate of T2DM remission and the prevention of atherosclerosis in the aorta in rats with streptozotocin-induced diabetes without obesity, and to explore the mechanism of DJB in protecting the aorta from atherosclerosis...

A 66-year-old man, presented with hematemesis and hemorrhagic shock, was transported to our institution. Computed tomographic examination suggested a pseudo-aneurysm formed by bleeding from aorto-esophageal fistula( AEF). We planned staged operations. At first, in an emergent operation, graft replacement of descending aorta, was performed under partial cardiopulmonary bypass, by left thoracotomy approach. AEF was 5 mm in diameter, and existed inside of normal-diameter and non-aneurysmal aortic intima. AEF orifice into pseudo-aneurysm was closed with aortic wall and was sutured tightly...

Median arcuate ligament (MAL) syndrome or celiac artery compression occurs secondary to diaphragmatic compression of the celiac artery and the corresponding neural structures of the celiac plexus. Typically, patients present with postprandial abdominal pain, nausea, vomiting, and weight loss. Diagnostically, various radiologic studies are used to document impingement of the celiac artery including ultrasound, computed tomography, aortograms, and magnetic resonance imaging. Historically, open approaches to the aorta and the celiac artery are performed to release the MAL and relieve compression of the celiac artery and the plexus...

BACKGROUND/AIM: Endovascular treatment of thoracic aortic diseases is an adequate alternative to open surgery. This method was firstly performed in Serbia in 2004, while routine usage started in 2007. Aim of this study was to analyse initial experience in endovacular treatment of thoracic aortic diseses of three main vascular hospitals in Belgrade - Clinic for Vascular and Endovascular Surgery of the Clinical Center of Serbia, Clinic for Vascular Surgery of the Military Medical Academy, and Clinic for Vascular Surgery of the Institute for Cardiovascular Diseases "Dedinje"...

We present the case of a 30-year-old female suffering from a type five maturity onset diabetes of the young deficiency, resulting in type 1 diabetes and terminal renal insufficiency. She also had chronic and refractory pruritis due to primary sclerosing cholangitis-like fibrosis. She underwent combined en bloc liver and pancreas transplantation and kidney transplantation. The postoperative course was complicated by a gastric outlet obstruction due to compression of the native gastroduodenal junction by the donor aortic tube...

A 47-year-old female presented to the emergency department complaining of diffuse abdominal pain and melena. She previously had a Bard G2X inferior vena cava filter placed before undergoing a laparoscopic Roux-en-Y gastric bypass 3 years before her current presentation. She had a history of an anastomotic ulcer that was treated medically. A repeat endoscopic evaluation revealed no evidence of a recent bleed and the ulcer was healed. Computed tomography revealed evidence of multiple filter struts penetrating through the caval wall into the duodenum and aorta...

OBJECTIVE: Improvement of vein graft patency may be highly beneficial in coronary artery bypass grafting, but graft degeneration is considered to be one of the main pathophysiologic causes for vein graft failure. Because peroxisome proliferator-activated receptor-gamma activator pioglitazone was recently reported to possess pleiotropic protective effects on various organs and tissues, we conducted experiments to test the hypothesis that pioglitazone could prevent graft degeneration, leading to the preservation of vein graft integrity...

BACKGROUND: Celiac artery compression syndrome (CACS) remains a controversial diagnosis, despite several reported series documenting therapeutic efficacy of CA decompression. Traditional therapy consists of open surgical decompression, but since 2000, five isolated case reports have been published in which CACS has been successfully treated with laparoscopic techniques. This approach was adopted as the sole initial therapy for CACS at the Johns Hopkins Hospital in 2002. This article reports the results of a unique surgical series that triples the reported worldwide experience with this therapy...

Aortoduodenal syndrome is a rare complication of an abdominal aortic aneurysm wherein the aneurysm sac obstructs the patient's duodenum. It presents with the symptoms of an upper gastrointestinal tract obstruction and requires surgical intervention to relieve it. Previously, gastric bypass surgery was advocated, but now aortic replacement is the mainstay of treatment. We report a case of a 67-year-old woman whose aortoduodenal syndrome was successfully managed and review the literature on this topic.

The patient was a 47-year-old man who was discovered to have Borrmann type 4 cancer of the cardiac region of the stomach associated with esophageal invasion during upper GI endoscopy and was histopathologically diagnosed with poorly-differentiated adenocarcinoma. Invasion of the aorta was suspected based on a CT examination, and resection was judged to be impossible. Since the tumor was associated with impaired patency, after first inserting a metallic stent, the patient was treated with 4 cycles of S-1 100 mg/body for 2 weeks and paclitaxel (PTX) 120 mg/body by intravenous drip infusion on days 1 and 15 for 2 weeks followed by a 2-week rest period...

OBJECTIVE: To investigate whether weight loss after bariatric surgery (gastric bypass) is associated with changes in aortic function (an important determinant of left ventricular function) and in left ventricular function, in morbidly obese individuals 3 and 36 months after surgery. METHODS: We used echocardiography to evaluate 60 obese individuals [body mass index (BMI) > 40 kg/m2] who underwent surgery and 20 obese individuals who neither underwent surgery nor lost weight, at baseline and at 3 and 36 months of follow-up, and 40 lean individuals (BMI < 25 kg/m2) of similar age, sex and risk factors, at baseline...

BACKGROUND: In multiple bypass surgery, when the ascending aorta cannot be used as an inflow, it is sometimes necessary to use an abdominal artery. This technique is useful when a re-median sternotomy might damage a patent graft in patients undergoing reoperations or when the gastroepiploic artery is unsuitable for use as a graft. METHODS: The subjects were 17 patients in whom an abdominal artery was used as an inflow. In these 17 patients, 9 underwent surgery for the first operation, while 8 underwent surgery for the reoperation...
