PANCREATICODUODENAL ARTERIES ANEURYSMS: EVALUATION OF FREQUENCY AND ASSOCIATION WITH CELIAC ARTERY STENOSIS DUE TO COMPRESSION BY MEDIAN ARCUATE LIGA…
2019
The aim of the study is to evaluate the prevalence of pancreaticoduodenal arteries (PDA) aneurysms in a large population, and to define possible correlations with celiac artery stenosis due to compression by the median arcuate ligament. Radiological reports of abdominal contrast-enhanced CT scans of 18,180 patients were scrutinized to identify patients with true PDA aneurysms. Two abdominal radiologists classified the aneurysms according to size, location and morphology and scored the presence of celiac artery stenosis due to either median arcuate ligament compression or atherosclerotic disease. Eleven true PDA aneurysms were identified in 10 patients. Nine out of 10 patients had stenosis o…
Microencapsulation of Enteric Bacteriophages in a pH-Responsive Solid Oral Dosage Formulation Using a Scalable Membrane Emulsification Process
2019
A scalable low-shear membrane emulsification process was used to produce microencapsulated Escherichia coli-phages in a solid oral dosage form. Uniform pH-responsive composite microparticles (mean size ~100 µ
Development of Gut-Associated Lymphoid Tissues
2015
The intestinal mucosa is one of our largest and most exposed body surfaces, thus creating a vital need for efficient immune responses. In order to coordinate those, the mucosal immune system comprises several organized lymphoid structures; the best-studied ones are mesenteric lymph nodes, Peyer’s patches, cryptopatches, and isolated lymphoid follicles. Their developmental requirements and time frames overlap to a certain extent, but are greatly divergent in many aspects. Furthermore, they can be influenced by a number of environmental impacts, such as food or the intestinal microbiota. In the following chapter we will try to shed some light on the processes that occur during the development…
Surgical anatomy applied to transperitoneal approaches of the abdominal aorta and visceral trunks. Dynamic article.
2020
Access to the abdominal aorta and its visceral trunks is possible through several approaches. Dissections of five cadavers performed during three National Surgical Anatomy courses applied to Aorta, Hepatobiliopancreatic and Digestive Surgery. Videos and pictures were taken throughout the dissections and showed different abdominal aorta approaches. Abdominal aorta and visceral trunks approaches: longitudinal inframesocolic access, supraceliac clamping, celiac trunk dissection, superior mesenteric artery approaches (retroperitoneal after Kocher menoeuvre, supramesocolic or inframesocolic), Cattell-Braasch manoeuvre and mattox manoeuvre: retrorenal and prerenal. Correct knowledge of the intraa…

Isolated dissection of the superior mesenteric artery: a case report and literature review
2014
Isolated dissection of the superior mesenteric artery is rare; it is predominantly observed in men with the highest incidence in those over 40 years old. Contrast-enhanced multi-detector computed tomography is considered essential for the diagnosis, therapeutic management and follow-up. The therapeutic approach ranges from conservative medical treatment to surgery or endovascular stent placement, but there are, to date, no approved guidelines. We report the case of a 68-year old man who entered our Emergency Department just for mild abdominal pain, which later proved to be due to acute dissection of the superior mesenteric artery.
Das »Nußknacker-Syndrom« der Vena renalis (Arteria-mesenterica-superior-Syndrom) als Ursache gastrointestinaler Beschwerden
2008
History and clinical findings Since the age of 19 a now 22-year-old man had complained of intermittent abdominal pain, irregular stools and paroxysmal tachycardia. The only preceding illness had been a single episode of iron-deficiency anemia. A laparoscopy, done 8 months after the onset of symptoms, had revealed an inflamed Meckel's diverticulum which was surgically removed. After transient improvement the symptoms recurred 5 months postoperatively. On admission to clarify the cause of the symptoms he had discrete abdominal pain on pressure, but physical examination was otherwise unremarkable. Investigations Routine biochemical tests and endoscopy were normal. Abdominal computed tomography…
Lymphatic Mesenteric Cyst, a Rare Cause of Surgical Abdominal Pain: Case Report and Review of the Literature
2020
A lymphatic mesenteric cyst (LMC) is a rare clinical entity, of unclear etiopathogenesis, which can arise in the abdominal cavity or retroperitoneum without a clear origin. We describe a case of a 74-year-old male presenting with abdominal pain that was non-specific and non-responsive to medical therapy. Laboratory tests clinical examination were inconclusive while the abdominal computed tomography (CT) scan showed a cystic lesion of the ileal mesentery. We performed an open surgical excision of the lesion with the resolution of clinical symptoms. The lesion resulted to be an LMC at the histological examination. At the five-year CT scan follow-up, we did not record any recurrences. LMCs pre…
Superior Mesenteric Artery Syndrome: Clinical, Endoscopic, and Radiological Findings.
2018
Background. The superior mesenteric artery (SMA) syndrome is a rare entity presenting with upper gastrointestinal tract obstruction and weight loss. Studies to determine the optimal methods of diagnosis and treatment are required. Aims and Methods. This study aims at analyzing the clinical presentation, diagnosis, and management of SMA syndrome. Ten cases of SMA syndrome out of 2074 esophagogastroduodenoscopies were suspected. A contrast-enhanced computed tomography (CECT) scan was performed to confirm the diagnosis. After, a gastroenterologist and a nutritionist personalized the therapy. Furthermore, we compared the demographical, clinical, endoscopic, and radiological parameters of these …
Acute and Chronic Captopril, but Not Prazosin or Nifedipine, Normalize Alterations in Adrenergic Intracellular Ca2+ Handling Observed in the Mesenter…
2004
The effect of hypertension and acute (36-h) or chronic (from age 6 to 16 weeks) antihypertensive treatment with prazosin (2 mg kg(-1) per day), nifedipine (50 mg kg(-1) per day), or captopril (50 mg kg(-1) per day) on Ca2+ mobilization due to alpha1-adrenoceptor activation was analyzed in functional studies using arterial rings [four conductance/distributing vessels: aorta, main mesenteric, iliac, and tail arteries and two resistance vessels; first and second small mesenteric artery branches obtained from spontaneously hypertensive rats (SHR, 6 and 16 weeks old) and age-matched Wistar Kyoto rats (WKY)]. Maximal response to noradrenaline in the presence of extracellular Ca2+ is not affected …
