Arterioscler Thromb Vasc Biol 2020 Jul 2:ATVBAHA120314491. Epub 2020 Jul 2.

From the Center for Thrombosis and Hemostasis (CTH), University Medical Center of the Johannes Gutenberg University of Mainz (JGU), Germany (S.A., E.W., G.P., H.F., F.B., M.M., F.M., A.G., M.B., M.S., I.B., K.G., K.K., K.J., C.R.).

Objective: Recruitment of neutrophils and formation of neutrophil extracellular traps (NETs) contribute to lethality in acute mesenteric infarction. To study the impact of the gut microbiota in acute mesenteric infarction, we used gnotobiotic mouse models to study whether gut commensals prime the reactivity of neutrophils towards NETosis. Approach and Results: We applied a mesenteric ischemia-reperfusion (I/R) injury model to germ-free (GF) and colonized C57BL/6J mice. Read More

Why is SARS-CoV-2 infection more severe in obese men? The gut lymphatics - Lung axis hypothesis.

Med Hypotheses 2020 Jun 23;144:110023. Epub 2020 Jun 23.

Department of Gastroenterology, IBD and Nutritional Support, CHU Paris Nord-Val de Seine, Beaujon Hospital, Clichy, France.

Consistent observations report increased severity of SARS-CoV-2 infection in overweight men with cardiovascular factors. As the visceral fat possesses an intense immune activity, is involved in metabolic syndrome and is at the crossroad between the intestines, the systemic circulation and the lung, we hypothesized that it plays a major role in severe forms of SARS-CoV-2 infection. SARS-CoV2 presents the ability to infect epithelial cells of the respiratory tract as well as the intestinal tract. Read More

En Bloc Celiac Axis Resection for Pancreatic Cancer: Classification of Anatomical Variants Based on Tumor Extent.

J Am Coll Surg 2020 Jul 15;231(1):8-29. Epub 2020 May 15.

Division of Hepatobiliary and Pancreas Surgery, Mayo Clinic College of Medicine, Rochester, MN.

Background: En bloc celiac axis resection (CAR) for pancreatic cancer is considered increasingly after modern neoadjuvant chemotherapy (NAC). Appleby and distal pancreatectomy with CAR are anatomically inaccurate terms, as tumors can extend beyond celiac axis proper, requiring concurrent resection of the proper hepatic artery and/or superior mesenteric artery.

Study Design: A 3-level classification for CAR (class 1, 2, or 3) was developed after retrospective review of an arterial resection database describing anatomical variants that dictate pancreatectomy-type, formal arterial revascularization, and gastric preservation. Read More

Retrograde Recanalization of the Celiac Artery via the Pancreaticoduodenal Arcade as a Safe and Valid Alternative to Antegrade Access.

Vasc Endovascular Surg 2020 May 18:1538574420927132. Epub 2020 May 18.

Department of Diagnostic and Interventional Radiology, RWTH University Hospital Aachen, Aachen, Germany.

Purpose: The antegrade recanalization of an occlusion or high-grade stenosis of the celiac artery via the aorta often represents a technical challenge. A retrograde approach via the superior mesenteric artery and the pancreaticoduodenal arcade may be an alternative approach. Based on our experience, we assess the technical success and the short- and mid-term outcomes of this bailout procedure. Read More

Hyperspectral Imaging (HSI) in Acute Mesenteric Ischemia to Detect Intestinal Perfusion Deficits.

J Surg Res 2020 May 8;254:7-15. Epub 2020 May 8.

Department of Visceral-, Transplantation-, Thoracic and Vascular Surgery, University Hospital Leipzig, Leipzig, Germany.

Background: Acute mesenteric ischemia is a life-threatening acute condition, which requires an interdisciplinary approach, including vascular recanalization and surgical treatment. Visual evaluation of intestinal perfusion might be misleading, and therefore, additional tools are necessary to reliably be able to resect the ischemic intestine. Hyperspectral imaging (HSI) has been shown to be feasible and safe for real-time assessment of tissue perfusion in visceral surgery but has never been used in cases of acute mesenteric ischemia.

Autotaxin inhibition attenuates endothelial permeability after ischemia-reperfusion injury.

Clin Hemorheol Microcirc 2020 May 4. Epub 2020 May 4.

Department of Surgery, University of California San Francisco East Bay, Oakland, CA, USA.

Background: Autotaxin (ATX-secretory lysophospholipase D) is the primary lysophosphatidic acid (LPA) producing enzyme. LPA promotes endothelial hyper-permeability and microvascular dysfunction following cellular stress.

Objective: We sought to assess whether ATX inhibition would attenuate endothelial monolayer permeability after anoxia-reoxygenation (A-R) in vitro and attenuate the increase in hydraulic permeability observed after ischemia-reperfusion injury (IRI) in vivo. Read More

Acute mesenteric ischemia: a review of the main imaging techniques and signs.

Radiologia 2020 May 5. Epub 2020 May 5.

Hospital Clínico Universitario Lozano Blesa, Zaragoza, España.

Acute mesenteric ischemia is an abdominal emergency because reduced blood flow to bowel loops rapidly leads to irreversible necrosis and death. This paper reviews the different conditions (arterial, venous, low-flow states) that can result in reduced blood flow to bowel loops. Since the clinical and laboratory findings are nonspecific, imaging tests play an important role in the diagnosis of mesenteric ischemia. Read More

Predictors of transmural intestinal necrosis in patients presenting with acute mesenteric ischemia on computed tomography.

Abdom Radiol (NY) 2020 May 7. Epub 2020 May 7.

Division of Cardiovascular Imaging, Department of Radiology, Massachusetts General Hospital, Boston, MA, USA.

Purpose: The purpose of this study was to identify the significant imaging predictors of transmural intestinal necrosis in patients with acute mesenteric ischemia (AMI).

Methods: The medical records and CT imaging of 48 patients between 2011 and 2019 suspected of having AMI that underwent exploratory laparotomy with bowel resection and pathological confirmation of ischemic bowel injury were retrospectively reviewed. Using histopathology as a gold standard, various parameters related to vascular insufficiency and bowel injury were analyzed and correlated with outcome of ischemic bowel necrosis using nonparametric tests.

Surg Infect (Larchmt) 2020 May 5. Epub 2020 May 5.

Department of Surgery, Faculty of Medicine and Dentistry, University of Alberta, Edmonton, Alberta, Canada.

Acute intestinal ischemia-reperfusion injury (AIIRI) is a devastating clinical condition relevant to multiple diseases processes, including sepsis, trauma, transplantation, and burns. An AIIRI is a contributor to the development of multiple organ dysfunction syndrome (MODS). Oncostatin M (OSM)/oncostatin M receptor (OSMR) signaling is an unrecognized and novel candidate pathway for the mediation of MODS. Read More
