RATIONAL: Acute lung injury (ALI) is a common complication after intestinal ischemia and reperfusion (I/R) injury that can lead to acute respiratory distress syndrome (ARDS). We have previously demonstrated that females are protected against lung damage induced by intestinal I/R through an estrogen mediated mechanism. OBJECTIVES: to investigate the effect of obesity on ALI induced by intestinal I/R in female mice. METHODS: C57Bl/6 female mice were fed with a standard low-fat diet (SD) or a high-fat diet (HFD) for 9 weeks...

BACKGROUND: Nonocclusive mesenteric ischemia (NOMI) is a mesenteric arterial spasm and intestinal ischemia. This disease is a highly lethal disease because diagnosis and decision of appropriate treatments are often difficult. Operations cannot resolve the spasms and may worsen the situation. However, the safety and effectiveness of catheterization for NOMI with aortic dissection (AD) have not yet been elucidated. Here, we report a successful case of early diagnosis and treatment of NOMI with type B AD involving the superior mesenteric artery (SMA) using the intra-arterial infusion of a vasodilator via the SMA...

Neuroendocrine tumors represent a heterogeneous group of neoplasms that arise from neuroendocrine cells and secrete various peptides and bioamines. While gastrointestinal neuroendocrine tumors, commonly called carcinoids, account for about 2/3 of all neuroendocrine tumors, they are relatively rare. Small intestine neuroendocrine tumors originate from intestinal enterochromaffin cells and represent about 1/4 of small intestine neoplasms. They can be asymptomatic or cause nonspecific symptoms, which usually leads to a delayed diagnosis...

BACKGROUND AND OBJECTIVES: Without prompt superior mesenteric artery (SMA) revascularization, acute mesenteric ischemia (AMI) frequently leads to death or short bowel syndrome (SBS). In SBS patients, persistent or chronic intestinal ischemia (PII) of the remnant bowel can lead to recurrences of AMI. Since SMA revascularization is sometimes unfeasible, celiac artery (CA) revascularization may improve blood supply to the remnant bowel. The aim of this study was to describe and to assess our experience of the CA revascularization in case of SMA occlusion unsuitable for revascularization in the setting of PII in SBS patients...

BACKGROUND: Lung inflammation is one of the main consequences of intestinal ischemia reperfusion (intestinal IR) and, in severe cases, can lead to acute respiratory distress syndrome and death. We have previously demonstrated that estradiol exerts a protective effect on lung edema and cytokine release caused by intestinal IR in male rats. MATERIALS AND METHODS: We investigated the role of estradiol on the generation of interleukin (IL)-1β, IL-10, vascular endothelial growth factor (VEGF), and cytokine-induced neutrophil chemoattractant 1 (CINC-1) in a female rat model of intestinal IR...

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...

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: 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...

The current standard care for acute mesenteric ischemia (AMEI) involves urgent revascularization and resection of the necrotic bowel. Since 2012, we have used an AMEI protocol of our own design, which focused on early treatment and allowed interventional cardiologists to become involved when interventional radiologist was not available. A total of 8 patients were treated, and two interventional cardiologists performed all the stenting procedures. The procedure success rate was 100% in patients with non-calcified lesions (6/8)...

BACKGROUND: Damage control surgery (DCS) was a major paradigm change in the management of critically ill trauma patients and has gradually expanded in the general surgery arena, but data in this setting are still scarce. The study aim was to evaluate outcomes of DCS in patients with general surgery emergencies. METHODS: Between 2005 and 2015, 164 patients (104 men, age 66) underwent DCS for non-traumatic abdominal emergencies. The decision to perform DCS was triggered by the presence of at least one trauma DCS criterion: hypotension (<70 mmHg), hypothermia (<35 °C), acidosis (pH < 7...

OBJECTIVE: The association of antiphospholipid antibody syndrome (APS) and hypercoagulability is well known. Arterial compromise leading to ischemia of organs and/or limbs in patients with APS is uncommon, frequently unrecognized, and rarely described. We evaluated our institutional experience. METHODS: Retrospective review was conducted. From August 2007 to September 2016, 807 patients with diagnosis of APS were managed in our Institution. Patients with primary and secondary APS who required interventions were examined...

The presence of the meandering mesenteric artery, which is a nonconstant tortuous arterial component unifying the peripheral intestinal circulation, is evidence of chronic occlusive disease of the main intestinal arteries. This collateral intestinal arterial pathway, when present, must be preserved in any abdominal intervention, as it is often the only remaining arterial supply of the intestine; its ligation can be accompanied by intestinal ischemia. We present herein, the case of a 42-year-old man, heavy smoker, who had chronic mesenteric ischemia without particular clinical manifestations till the hospitalization for acute myocardial infarction for which he underwent balloon angioplasty and stenting of the left circumflex coronary artery...

BACKGROUND: Damage control surgery and open abdomen (OA) have been extensively used in the severe traumatic patients. However, there was little information when extended to a nontrauma setting. The purpose of this study was to evaluate whether the liberal use of OA as a damage control surgery adjunct improved the clinical outcome in acute superior mesenteric artery occlusion patients. STUDY DESIGN: A single-center, retrospective cohort review was performed in a national tertiary surgical referral center...

Quercetin, the active substance of tea, fruits and vegetables, exerts a broad spectrum of pharmacological activities and is considered to have potential therapeutic application. The present study was designed to investigate the beneficial effect of quercetin against experimental ischemia- reperfusion (IR) injury of the small intestine in rats. Quercetin was administrated intraperitoneally 30min before 1h ischemia of superior mesenteric artery with following reperfusion periods lasting 1, 4 and 24h. The male specific pathogen-free Charles River Wistar rats were used (n=45)...
