Pancreaticoduodenal artery aneurysms (PDA) are rare visceral aneurysms. Celiac trunk stenosis represents a common attributable aetiology for those aneurysms. Therefore, an alternative treatment approach, which differs from those isolated aneurysms, is recommended. We hereby present a 77-year-old male patient who was admitted with sudden onset of severe abdominal pain and significant drop in haemoglobin, occurring within a 24-hour interval. Contrast-enhanced computed tomography revealed a ruptured visceral aneurysm arising from the anterior branch of the inferior pancreaticoduodenal artery...

BACKGROUND: Laparoscopic complete mesocoloic excision (CME) with central vascular ligation for splenic flexure cancer is technically challenging because of its anatomical complexity. Although embryological and anatomical consideration should be helpful to perform CME in colorectal cancer surgery, such studies on the splenic flexure are lacking. METHODS: The splenic flexure is located embryologically between the terminal portion of the midgut and the beginning of the hindgut, and is supplied by the superior mesenteric and inferior mesenteric arteries...

The current study presents a mesenteric mesenchymal tumor case, with unusual features in diagnostic imaging and histology. A 16-year-old male was admitted to the hospital with abdominal pain. Computed tomography (CT) revealed an abdominal mass, 2 cm in diameter. The results of contrast-enhanced CT, magnetic resonance imaging and (18)F-fluorodeoxyglucose positron emission tomography indicated no specific features suggestive of its histology. Two arteries branching from the superior mesenteric artery were observed feeding the hypervascular tumor...

BACKGROUND: Treatment of symptomatic, chronic mesenteric ischemia is indicated to relieve symptoms and prevent acute ischemia and death. Current therapeutic options include endovascular and open surgery. The purpose of this prospective study was to evaluate the results of bypasses to the superior mesenteric artery arising from the infrarenal aorta or infrarenal aortic grafts. METHODS: From January 1999 to December 2016, 24 consecutive patients with a mean age of 61 years underwent a prosthetic bypass to the superior mesenteric artery...

Intestinal surgery is commonly performed to cure bowel obstruction in rabbits, but detailed descriptions of the arterial supply to the intestine are incomplete. We investigated anatomical variations of the distribution of the cranial mesenteric artery to the intestine in 33 New Zealand White rabbits by injecting colored latex into the arteries. The cranial mesenteric artery arose independently from the abdominal aorta at about 2.0 cm caudal to the celiac artery and branched off the pancreaticoduodenal, middle colic, ileocecocolic, jejunal and ileal arteries...

Necrotizing enterocolitis (NEC) is one of the most severe and unpredictable complications of prematurity. There are two possible mechanisms involved in the pathogenesis of NEC: individual inflammatory response and impaired blood flow in mesenteric vessels with secondary ischemia of the intestine. The aim of this study was to evaluate the possible relationship between polymorphisms: Il-1β 3953C>T, Il-6 -174G>C and -596G>A, TNFα -308G>A, and 86 bp variable number tandem repeat polymorphism of interleukin-1 receptor antagonist (Il-1RN VNTR 86 bp) and three polymorphisms that may participate in arteries tension regulation and in consequence in intestine blood flow impairment: eNOS (894G>T and -786T>C) and END-1 (5665G>T) and NEC in 100 infants born from singleton pregnancy, before 32 + 0 weeks of gestation, exposed to antenatal steroids therapy, and without congenital abnormalities...

A variant anatomy of the hepatic vasculature has a clinically significant role in hepatobiliary transplantation, resection, tumour embolisation as well as in extrahepatic abdominal surgeries involving the stomach, pancreas or gall bladder. During routine cadaveric dissection, we observed a case of unusually small calibre hepatic artery proper. An accessory hepatic artery was seen emerging from the superior mesenteric artery to the right hepatic lobe along with an accessory hepatic vein from the right hepatic lobe that drained directly into the inferior vena cava...

Visceral artery aneurysm (VAA) is very rare among vascular pathologies. Incidence reported in autopsy series and angiographic studies varies between 0.1% and 0.2%. Most cases are asymptomatic and are diagnosed as result of complications, or incidentally, when imaging is performed for another reason. Three percent of VAAs are superior mesenteric artery (SMA) terminal branch aneurysms. Intra- and/or extraperitoneal bleeding due to ruptured aneurysm is life-threatening condition and requires emergent intervention...

t Superior Mesenteric Artery (SMA) syndrome is an uncommon condition caused by mechanical obstruction of the distal third of the duodenum between the superior mesenteric artery and the abdominal aorta. SMA syndrome is associated with both operative and non-operative corrections of scoliosis, as well as anorexia nervosa, severe weight loss, tumors, burns, and other traumas.[1-4] We report an unusual case of SMA syndrome following corrective surgery for scoliosis in which post-operative gastric distension caused duodenal compression that subsequently resolved with gastric decompression, as opposed to the conventional, reverse series of events in which SMA syndrome causes the gastric dilatation...

INTRODUCTION: Intestinal malrotation is a congenital anomaly, and its occurrence in adults is rare. Colon cancer with intestinal malrotation is far more rare. We herein report two cases of colon cancer with intestinal malrotation treated with laparoscopic surgery and reviewed the literatures in Japan. PRESENTATION OF CASES: Case 1 involved a 78-year-old man. Abdominal enhanced computed tomography (CT) showed that the tumor was located in the sigmoid colon. Intraoperatively, the cecum and ascending colon were located along the midline and the small intestine occupied the right side of the abdomen...

OBJECTIVE: Acute mesenteric ischemia, one of the causes of acute abdominal pain due to occlusion of the superior mesenteric artery, has a fatal course as a result of intestinal necrosis. There is no specific laboratory test to diagnose acute mesenteric ischemia. The basis of treatment in cases of acute mesenteric ischemia is composed of early diagnosis, resection of intestinal sections with infarction, regulation of intestinal blood flow, second look laparotomy when required, and intensive care support...

BACKGROUND: During abdominal surgery, traction of the mesenterium provokes mesenteric traction syndrome, including hypotension, tachycardia, and flushing, along with an increase in plasma prostacyclin (PGI2). We evaluated whether postoperative complications are related to mesenteric traction syndrome during esophagectomy. METHODS: Flushing, hemodynamic variables, and plasma 6-keto-PGF1α were recorded during the abdominal part of open ( n = 25) and robotically assisted ( n = 25) esophagectomy...

BACKGROUND: With the introduction of complete mesocolic excision (CME) and the application of laparoscopic technique, surgery for colon cancer has become more standardized and the curative effect has improved [1]. The key points in laparoscopic right hemicolectomy are high ligation of main vessels and root dissection of lymph nodes. The wide range of variations in vascular architecture and intraoperative bleeding are common causes of prolonged surgical time, wound hemorrhage, and even transfer to the opening operation...

INTRODUCTION: Superior mesenteric artery (SMA) syndrome also known as Wilkie's syndrome is a rare condition caused by the entrapment of the third part of the duodenum between the aorta and the SMA. The incidence of Wilkie's syndrome range between 0.013% and 0.3%. The normal angle between the aorta and SMA has been described to range between 38° and 65°, whereas in Wilkie's syndrome this angle is reduced to less than 20° causing gastric outlet obstruction. CASE PRESENTATION: We report a case of a previously diagnosed 43 year-old male with SMA syndrome, whom had been conservatively managed for 5-years for recurrent admissions with symptoms of gastric outlet obstruction...

INTRODUCTION: Rupture of superior mesenteric artery aneurysm (SMAA) is a very rare and life-threatening condition, presenting with acute intraabdominal hemorrhage. CASE: The patient was hospitalized upon complaint of nonspecific severe abdominal pain. Diagnosis of SMAA was established by abdominal Doppler ultrasound that showed a pseudo-aneurysmal lesion with size of 76 × 47 mm at the superior mesenteric main branch. Endovascular stenting was not performed because of the wide neck in the segment of the jejunal branches from SMA and the risk of branch loss during treatment...

INTRODUCTION The superior mesenteric artery (SMA) syndrome, or Wilkie's syndrome, is a rare cause of postprandial epigastric pain, vomiting and weight loss caused by compression of the third part of the duodenum as it passes beneath the proximal superior mesenteric artery. The syndrome may be precipitated by sudden weight loss secondary to other pathologies, such as trauma, malignancy or eating disorders. Diagnosis is confirmed by angiography, which reveals a reduced aorto-SMA angle and distance, and contrast studies showing duodenal obstruction...
