BACKGROUND: Intestinal fatty acid-binding protein (I-FABP) has been shown to be of high diagnostic value in patients with acute mesenteric ischemia. Whether these results can be reproduced in critically ill patients on the ICU was to be investigated. MATERIALS AND METHODS: I-FABP was measured in serum and urine of 43 critically ill patients in ICU when mesenteric ischemia was suspected. Bowel ischemia was confirmed in 21 patients (group 1). 22 patients who survived at least seven days without confirmation of ischemia were assigned to group 2...

Animal models are needed to study and understand a human complex disease. Because of their similarities in anatomy, structure, physiology, and pathophysiology, the pig has proven its usefulness in studying human gastrointestinal diseases, such as inflammatory bowel disease, ischemia/reperfusion injury, diarrhea, and cancer. To understand the pathogenesis of these diseases, a number of experimental models generated in pigs are available, for example, through surgical manipulation, chemical induction, microbial infection, and genetic engineering...

Pneumatosis intestinalis is a radiographic finding of gas pockets within the bowel wall. It can be associated with a range of diagnoses, but the most life-threatening causes are mesenteric ischemia, bowel necrosis, and bowel obstruction. Here we present the case of a patient with multiple myeloma who had pneumatosis intestinalis due to gastrointestinal amyloidosis, which is a rare manifestation of systemic amyloid disease. The patient had both transthyretin (ATTR) amyloidosis and acquired apolipoprotein serum amyloid A (AA) amyloidosis that are not usually seen in conjunction with multiple myeloma, which is most commonly associated with light-chain (AL) amyloidosis...

BACKGROUND: Animal models are a central aspect in research on small bowel transplantation (SBTx). Among them, rats are the preferred species because of their widespread availability and cost effectiveness. Because the complexity of the surgical procedure could per se influence the outcome of an experiment, a standardized and comparable technique is important. Based on of the vast amount of different models and surgical techniques published to this point, a review seemed necessary to guide investigators when choosing the suitable model...

Abdominal pain, one of the major symptoms of chronic pancreatitis, is believed to be caused by obstruction of the pancreatic duct system by stones or strictures. This results in increased intraductal pressure and parenchymal ischemia. Surgical decompression of the duct and ductal drainage can achieve best pain relieve and slow the progression of the disease. We want to share our experience of surgical drainage of pancreatic duct in chronic pancreatitis in our hospital. We studied 20 cases operated in our hospital between January 2010 and October 2015...

BACKGROUND: Isolated small bowel perforation following blunt abdominal trauma (BAT) is an uncommon situation with high morbidity and mortality rates, and delayed small bowel perforation is even rarer. The pathophysiology of this condition is not clear in all cases. To the best of our knowledge, this is the first case report of delayed small bowel perforation following BAT with extensive portomesenteric vein gas. CASE REPORT: A 33-year-old male patient was admitted to the emergency department after a car accident...

Intussusception is often misdiagnosed as a cause of bowel ischemia and obstruction among adults due to its relatively rare presentation outside of the paediatric population. Ultrasound is often the first-line investigation for non-specific abdominal pain and can identify the presence of intussusception. In the adult population, it is essential to evaluate for causes and consequences of intussusception; as a result, computerised tomography is often deemed necessary. However, contrast-enhanced ultrasound allows for evaluation of potential causes and complications, including a neoplastic lead point and ischaemia of the bowel, whilst avoiding ionising radiation or nephrotoxic iodinated contrast...

OBJECTIVE: The purpose of this study was to report prospective data of an off-the-shelf fenestrated endograft (Zenith p-Branch; Cook Medical, Bloomington, Ind) from four centers for the treatment of patients with pararenal abdominal aortic aneurysms. METHODS: Data were combined from four single-center investigational studies conducted in the United States and Europe. The p-Branch endograft consists of a proximal off-the-shelf component incorporating a scallop for the celiac artery, a superior mesenteric artery fenestration, and two conical pivot fenestrations to preserve flow to the renal vessels...

BACKGROUND: Up to 40% of abdominal aortic aneurysms (AAAs) have coexistent iliac artery aneurysms (IAAs). In the past, successful endovascular repair required internal iliac artery (IIA) embolization, which can lead to pelvic or buttock ischemia. This study describes a technique that uses a readily available solution with a minimally altered off-the-shelf bifurcated graft in the IAA to maintain IIA perfusion. METHODS: From August 2009 to May 2015, 14 patients with AAAs and coexisting IAAs underwent repair with a bifurcated-bifurcated approach...

OBJECTIVE: Comparing costs between centers is difficult because of the heterogeneity of vascular procedures contained in broad diagnosis-related group (DRG) billing categories. The purpose of this pilot project was to develop a mechanism to merge Vascular Quality Initiative (VQI) clinical data with hospital billing data to allow more accurate cost and reimbursement comparison for endovascular aneurysm repair (EVAR) procedures across centers. METHODS: Eighteen VQI centers volunteered to submit UB04 billing data for 782 primary, elective infrarenal EVAR procedures performed by 108 surgeons in 2014...

BACKGROUND: Nonocclusive mesenteric ischemia can cause intestinal infarction but the diagnosis is challenging. This prospective study evaluated three plasma biomarkers of intestinal infarction after cardiac surgery. MATERIALS AND METHODS: Patients were recruited after cardiac surgery if they required laparotomy (with or without intestinal resection) for suspected nonocclusive mesenteric ischemia. Plasma levels of D-lactate, intestinal fatty acid-binding protein (i-FABP), and smooth muscle actin (SMA) before laparotomy were measured...

Large bowel perforation is an abdominal emergency that results from a wide range of etiologies. Computed tomography is the most reliable modality in detecting the site of large bowel perforation. The diagnosis is made by identifying direct CT findings such as extraluminal gas or contrast and discontinuity along the bowel wall. Indirect CT findings can help support the diagnosis, and include bowel wall thickening, pericolic fat stranding, abnormal bowel wall enhancement, abscess, and a feculent collection adjacent to the bowel...

We report an usual case of hepatic portal venous gas (HPVG) in the setting of acute pancreatitis and small bowel ischemia. Interestingly, the HPVG disappeared within 2 hours of the original computed tomography scan, despite the patient having small bowel ischemia. The patient had a complicated clinical course, dying 62 days postadmission. This case highlights that HPVG in setting of acute pancreatitis and small bowel ischemia has a very high morbidity and mortality, requiring early detection and aggressive surgical management...

Background: Mesenteric ischemia is a challenging diagnosis. Delay in diagnosis can lead to extent bowel necrosis and poor outcomes. Ischemia and reperfusion syndrome plays an important role in this scenario. Aim: To access effects of different post-conditioning cycles on mesenteric ischemia-reperfusion syndrome. Method: Twenty-five rats were assigned into five groups: Sham, used to establish normal parameters; control group, submitted to mesenteric ischemia for 30 min; in groups GP3, GP1 and GP30, ischemia was followed by post-conditioning protocol, which consisted of 1 cycle of 3 min (GP3), 3 cycles of 1 min (GP1) or 6 cycles of 30 s (GP30), respectively...

We report a case of inferior mesenteric artery aneurysm after the replacement of the thoracoabdominal aorta for a chronic dissected thoracoabdominal aortic aneurysm in which the celiac artery and superior mesenteric artery were occluded. We performed the resection of the inferior mesenteric artery aneurysm and the revascularization of the superior mesenteric artery, inferior mesenteric artery, and the meandering artery. The patient's postoperative course was uneventful, without bowel ischemia. From the findings of intraoperative flow measurement of the visceral arteries, revascularization of the SMA was judged to be appropriate in this situation...

Inferior mesenteric artery (IMA) aneurysms are a rare entity, attributing to 1% of Splanchnic aneurysms (Edogawa S, Shibuya T, Kurose K et al. Inferior mesenteric artery aneurysm: case report and literature review. Ann Vasc Dis 2013;6:98-101), often found incidentally on evaluation for other intra-abdominal pathologies. Similar to other visceral arterial aneurysms, there is an estimated 20-50% risk of potentially fatal rupture and repair is generally recommended. We report 2 patients with IMA aneurysms, using them as cases to illustrate feasibility of both open and endovascular management options...
