NEC is an idiopathic intestinal mucosal injury that may progress to transmural bowel necrosis without mesenteric ischemia. NEC usually affects 7- to 10-day-old neonates following enteral feeding. A 10-month-old girl with no history of laparotomy underwent LDLT for acute liver failure. After starting enteral feeding on postoperative day 5, she developed abdominal distention. Diffuse PVG and PI were detected by radiologic modalities. Exploratory laparotomy revealed patchy necrosis of the intestine without perforation...

OBJECTIVE: Historically, patients with chronic mesenteric ischemia (CMI) are underweight with a low body mass index (BMI). However, with the recent obesity epidemic many of these patients now are overweight with a high BMI. We evaluated the impact of BMI on outcomes after mesenteric revascularization for CMI. METHODS: A retrospective chart review of patients undergoing open or endovascular mesenteric revascularization for CMI between January 2000 and June 2015 was performed...

Acute mesenteric ischemia resulting from mesenteric arterial thrombosis is a life-threatening cardiovascular complication with symptoms ranging from sudden-onset abdominal pain to vague symptoms of several days' duration. Although contrast-enhanced computed tomography is an excellent diagnostic tool, detection of the disease before the development of permanent intestinal injury is still difficult. Endovascular treatment is usually successful in restoring intestinal blood flow acutely. Chronic mesenteric ischemia requires urgent detection and therapy in order to prevent irreversible intestinal ischemia...

Background: Intestinal ischemia is often caused by a malperfusion of the upper mesenteric artery. Since the intestinal mucosa is one of the most rapidly proliferating organs in human body, this tissue can partly regenerate itself after the onset of ischemia and reperfusion (I/R). Therefore, we investigated whether glycine, sodium pyruvate, and resveratrol can either support or potentially harm regeneration when applied therapeutically after reperfusion injury. Methods: I/R of the small intestine was initiated by occluding and reopening the upper mesenteric artery in rats...

BACKGROUND: Intestinal ischemia-reperfusion (I-R) injury is a serious abdominal condition leading to multiple organ failure with high mortality. However, no reliable treatment is available. Novel redox nanoparticle (RNPO) was recently developed, and its efficacy for several intestinal inflammatory conditions has been reported. To this end, the aim of this study was to investigate the therapeutic effects of RNPO on intestinal I-R injury in mice. METHODS: Ischemia was induced in the small intestine of C57BL/6 mice by occluding the superior mesenteric artery for 45 min under anesthesia followed by reperfusion for 4 h...

REVIEW
Andreas Selberherr, Martin B Niederle, Bruno Niederle
Although the majority of neuroendocrine tumors of the small intestine (siNETs) classified as low-grade G1 or G2 show slow local growth, they are frequently diagnosed at an advanced stage of metastatic disease. The surgical treatment is curative in stages I-III or palliative in stage IV in an attempt to avoid local complications of bowel obstruction and ischemia of the small bowel by unremoved lymph node metastases. Individualized surgical procedures performed by experienced surgeons considering tumor multifocality and the primary extent of lymph node metastases along the mesenteric vessels are recommended to remove as much tumor volume as possible, while avoiding major complications intraoperatively and small bowel syndrome postoperatively...

Intestinal ischemia/reperfusion (I/R) can lead to tissue damage associated with inflammation and mucosal apoptosis. Ischemic postconditioning (IPostC), a series of repeated, brief, intermittent periods of ischemia and reperfusion, has beneficial effects against I/R-induced injury in the heart and intestine, although the underlying mechanisms for these effects remain unclear. We evaluated the involvement of microRNA-21 (miR-21) in the protective effects of IPostC in a rat model of I/R induced by superior mesenteric artery occlusion and reopening...

OBJECTIVE: Isolated spontaneous dissection of the superior mesenteric artery (SMA) and celiac artery (CA) remains a rare condition; however, it has been increasingly noted incidentally on diagnostic imaging. The purpose of this study was to examine the natural history and outcomes of patients presenting with isolated spontaneous mesenteric artery dissection (SMAD). We hypothesized that most SMADs can be treated nonoperatively. METHODS: This was a single-center retrospective review of patients presenting with the diagnosis of SMAD between 2006 and 2016...

The aim of our study was to analyse the possible protective effect of quercetin application during the jejunal ischemia-reperfusion injury (IRI) in rats. Quercetin was administered intraperitoneally 30min before 1h ischemia of superior mesenteric artery with following 24h lasting reperfusion period. The male specific pathogen-free (SPF) Charles River Wistar rats were used. In the group with applied quercetin, the significantly increased (p<0.001) levels of anti-inflammatory cytokine IL10 were observed both in the blood serum and jejunal tissue...

Treatment of chronic mesenteric ischemia has evolved over the last two decades. Endovascular therapy is now the treatment of choice for patients with lesions amenable to such an approach. Open revascularization remains the standard of care but is frequently being reserved for lesions containing intraluminal thrombus or severe calcification. In most cases, celiac axis (CA) stenting is not needed since revascularization of the superior mesenteric artery (SMA) alone results in symptomatic resolution. This report describes a case of a patient with chronic mesenteric ischemia and diffuse gastric ulcers found to have a common origin of the SMA and CA that was treated endovascularly using a bifurcated stent technique...

BACKGROUND: Acute mesenteric ischemia poses a diagnostic challenge due to nonspecific clinical clues and lack of awareness owing to its rarity. Ischemia due to mesenteric venous thrombosis has a good prognosis compared to arterial cause and can be managed conservatively with early diagnosis. The portomesenteric venous system is an unusual site of thrombosis in patients with protein S deficiency, and its thrombosis is an uncommon cause of acute mesenteric ischemia. CASE PRESENTATION: We present a case of a 27-year-old Mongolian man who presented with acute abdominal pain increasing in severity, and refractory to repeated attempts at treatment with a misdiagnosis of acute peptic ulcer disease...

Pancreatic ductal adenocarcinoma is one of the leading causes of cancer-related deaths. With surgical resection being the only definitive treatment, improvements in technique has led to an increase in number of candidates undergoing resection by inclusion of borderline resectable disease patients to the clearly resectable group. Post-operative complications associated with pancreaticoduodenectomy and distal pancreatectomy include delayed gastric emptying, anastomotic failures, fistula formation, strictures, abscess, infarction, etc...

Anastomotic leakage is more frequently reported in colonic anastomoses. Ischemia reperfusion injury is one of the main reasons for anastomotic leakage. Simvastatin is known to prevent tissue damage induced by free oxygen radicals after ischemia reperfusion injury. The effect of simvastatin on colonic anastomosis impaired by ischemia reperfusion injury is investigated. Single layer, end-to-end colocolic anastomosis after 0.5-cm colon resection was performed in Wistar Albino rats. In Group 1 (control) (n = 10), colonic anastomosis without I-R was performed...
