BACKGROUND: The anatomic variations of the visceral arteries are not uncommon. The liver arterial blood supply shows 50% variability between humans, with the most common anatomy being one hepatic artery arising from the celiac trunk and one pancreatico-duodenal arcade between the celiac trunk and the superior mesenteric artery. Occlusion of one artery are mostly asymptomatic but may become clinically relevant when surgery of the liver, bile duct or the pancreas is required. If these pathologies are not reversible, an oncologic pancreatic head resection cannot be performed...

Endovascular approach is now a safe and effective technique for the elective treatment of a thoraco-abdominal aneurysm. This technique has significantly reduced the morbi-mortality for elective surgery. Moreover, it can permit to treat patients with a high surgical risk who are not eligible for open surgery. The permanent availability of endovascular material opens the door for treating a complex emergency thoraco-abdominal aneurysm. Here, we present the case of an 81-year-old man who had a rapidly evolving salmonella-infected aortic thoraco-abdominal Type IV pseudoaneurysm...

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...

Background: Preoperative hypoxemia is a frequent complication of acute Stanford type A aortic dissection (ATAAD). The aim of the present study was to determine which factors were associated with hypoxemia. Methods: A series of data were collected in a statistical analysis to evaluate preoperative hypoxemia in patients with ATAAD. After retrospectively analyzing data for 172 patients, we identified the risk factors for preoperative hypoxemia. Hypoxemia was defined by an arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2 /FiO2 ) ratio of 200 or lower...

OBJECTIVE: Fenestrated endovascular aneurysm repair (FEVAR) has been used successfully to treat patients with juxtarenal abdominal aortic aneurysms (JAAAs). Barriers to wide adoption of FEVAR include complexity in planning of fenestration locations on endografts. The purpose of this study was to validate the use of automated planning software to design fenestrated endografts and to treat patients with complex abdominal aortic aneurysms. METHODS: Patients with JAAA who were not candidates for open repair were enrolled into the automated planning arm of an ongoing investigational device exemption clinical trial and treated with FEVAR...

Introduction The rupture of thoracoabdominal aneurysms (rTAA) represents one of the major challenges to the vascular surgeon. Recent developments in the endovascular armamentarium and the high mortality from open surgery make endovascular treatment an attractive option. Devices to be used in an emergency environment should be "off-the-shelf" and include, among others, EVAR snorkel/chimney and branched endoprosthesis (T-branch, Cook®). METHODS: We describe the case of a 70-year-old patient who was admitted to the emergency room due continuous low back pain with 3 days of evolution...

Celiac trunk stenosis is a relatively common finding; the most common causes of this obstruction are median arcuate ligament syndrome, pancreatitis, local invasion of various malignancies originating from the pancreatic body, atherosclerosis or it can be idiopathic. However, most such cases remain asymptomatic for a long period of time, especially due to the presence of a patent collateral circulation originating from the superior mesenteric artery. In certain cases, the patient might become symptomatic, diffuse post-prandial pain being reported...

BACKGROUND: Since the concept of intraductal tubulopapillary neoplasm (ITPN) was introduced in the current World Health Organization classification of tumors, the number of reports of ITPN occurrence has increased gradually. However, ITPN is usually located in the main pancreatic duct, with few reports of a branch duct ITPN. As a result, imaging protocols for the diagnosis of a branch duct ITPN have not been established. CASE PRESENTATION: We report a case of a concurrent presentation of a branch duct ITPN and intraductal papillary mucinous neoplasm (IPMN) in the head of the pancreas, with a superior mesenteric artery (SMA) aneurysm...

For colorectal surgeons, how to reduce anastomotic leakage after laparoscopic rectal cancer surgery remains to be challenging. We provide a brief discussion regarding the surgical skills required to prevent anastomotic leakage after rectal cancer surgery, such as the following: 1) Low ligation of inferior mesenteric vessel during laparoscopic total mesorectal excision can improve anastomotic tension and blood supply, thus reducing the risk of anastomotic leakage. While high ligation of inferior mesenteric artery results in poor blood supply and high tension in atastomotic site, thus increasing the risk of anastomotic leakage...

With popularity of robotic surgery system, robotic rectal cancer surgery is increasing. Precautionary measures of different perioperative periods should be taken to reduce the risk for anastomotic leakage. First, the general condition of patients should be acquainted and improved, and the risk for anastomotic leakage should be evaluated preoperatively. Preoperative neoadjuvant chemoradiotherapy may not increase the risk for anastomotic leakage after rectal surgery. The impact of routine bowel preparation to prevent anastomotic leakage needs to be verified further...

INTRODUCTION: Historically, the open approach to the abdominal aorta has been transperitoneal (TP). In comparison, a retroperitoneal (RP) incision exposes the lateral wall of the suprarenal aorta for clamp application and midline structures such as the duodenum and pancreas are not encountered. Proximal clamp position for open repair of juxtarenal abdominal aortic aneurysm (JR-AAA) is suprarenal, supra-superior mesenteric, or supraceliac. While RP and TP approaches have previously been compared for physiological reasons, there are currently no randomized controlled trials comparing these methods from an anatomical perspective...
