Hepatic portal venous gas (HPVG) is a rare ominous radiological sign usually indicative of mesenteric ischemia. Increased detection of HPVG has been associated with a growing number of non-ischemic causes. A 64-year-old gentleman following radical cystectomy and neobladder formation developed clinical signs suggestive of bowel obstruction. HPVG was demonstrated on abdominal imaging. Urgent laparotomy revealed no evidence of ischemia. We hypothesize an obstructed neobladder permitted gas to enter the mesenteric circulation...

Small bowel intussusception (SBI) in pediatric patients resolves spontaneously in the majority of cases. Pathologic small bowel intussusception with a lead point is rare in children. Ultrasound (US) is the preferred initial imaging study for the diagnosis of intussusception. We report a case of long-segment SBI and secondary bowel obstruction caused by a large hamartomatous polyp. This case emphasizes unique, atypical ultrasound findings that may be encountered in small bowel intussusception, with correlative radiographic, CT (computed tomography) and intra-operative findings...

OBJECTIVES: To identify predictive factors for irreversible transmural intestinal necrosis (ITIN) in acute mesenteric ischemia (AMI) and establish a risk score for ITIN. METHODS: This single-center prospective cohort study was performed between 2009 and 2015 in patients with AMI. The primary outcome was the occurrence of ITIN, confirmed by specimen analysis in patients who underwent surgery. Patients who recovered from AMI with no need for intestinal resection were considered not to have ITIN...

Purpose. Early recognition of acute mesenteric ischemia (AMI) can be challenging. Extensive bowel necrosis secondary to AMI is associated with high rates of mortality. The aim of this study was to investigate the association between preoperative serum lactate level and the extent of bowel ischemia in patients with AMI. Methods. Data of patients with abdominal pain and elevated serum lactate undergoing emergency laparotomy for suspected AMI within 24 hours of presentation was retrospectively abstracted. The length of the ischemic bowel segment was compared with the preoperative serum lactate level...

BACKGROUND: More than 80% of infrarenal aortic aneurysms are treated by endovascular repair. However, adoption of fenestrated and branched endovascular repair for complex aortic aneurysms has been limited, despite high morbidity and mortality associated with open repair. There are few published reports of consecutive outcomes, inclusive of all fenestrated and branched endovascular repairs, starting from the inception of a complex aortic aneurysm program. Therefore, we examined a single center's consecutive experience of fenestrated and branched endovascular repair of complex aortic aneurysms...

Mesenteric ischemia is a gut and life-threatening, medical and surgical, digestive and vascular emergency. Mesenteric ischemia is the result of an arterial or venous occlusion, a vasospasm secondary to low-flow states in intensive care patients, aortic clamping during vascular surgery or intestinal transplantation. Progression towards mesenteric infarction and its complications is unpredictable and correlates with high rates of mortality or a high risk of short bowel syndrome in case of survival. Thus, mesenteric ischemia should be diagnosed and treated at an early stage, when gut injury is still reversible...

OBJECTIVE: Occlusion of the internal iliac artery (IIA) may be necessary prior to endovascular aortoiliac aneurysm repair (EVAR) to prevent endoleak type II. We compared efficacy and clinical outcome after proximal occlusion of an unaffected IIA (ProxEmbx) using an Amplatzer vascular plug I (AVP) vs. distal occlusion of aneurysmatic IIA with coils and plugs (DistEmbx). METHODS: Between 2009 and 2012 22 patients underwent EVAR. In 9 patients with unaffected IIA occlusion was performed by a single AVP...

Transanal intestinal evisceration is an extremely rare pathologic condition. Its presentation is quite dramatic as it involves the small bowel eviscerating through a rectal wall defect intraluminally and exiting transanally. We present the case of a 91-year-old female with history of rectal bleeding due to local ischemia of the anterior rectal wall, who presented to us with intestinal loops extruding through the anus. The patient underwent prompt surgical intervention with segmental small bowel resection, resection of the rectum, and construction of an end colostomy, with a smooth postoperative recovery...

Oxidative stress is involved in pathophysiology and pathological conditions of numerous human diseases. Thus, understanding the mechanisms underlying the redox homeostasis in cells and organs is valuable for discovery of therapeutic drugs for oxidative stress-related diseases. Recently, by applying chemical biology approach with an ARE activator, BTZO-1, we found macrophage migration inhibitory factor (MIF) as a new regulator of antioxidant response element- (ARE-) mediated gene transcription. BTZO-1 and its active derivatives bound to MIF and protected cells and organs from oxidative insults via ARE activation in animal models with oxidative stress such as ischemia/reperfusion injury, inflammatory bowel diseases, and septic shock...

BACKGROUND: Non-occlusive mesenteric ischemia (NOMI) is ischemia of the mesentery that is caused by hypoperfusion or vasospasm without any thrombosis. NOMI is difficult to diagnose by physical examination alone. Although angiographic examination of the superior mesenteric artery (SMA) is the usual diagnostic method used, it is an invasive examination. Usually, a long range of the bowel becomes discontinuously necrotic in NOMI. Here, we report a rare case of NOMI localized in the transverse colon that was diagnosed by computed tomography (CT) angiography which is a minimally invasive examination...

The plastic hardener methyl ethyl ketone peroxide is unstable peroxide that releases free oxygen radicals. Ingestion of this compound induces widespread liver necrosis, severe metabolic acidosis, corrosive esophagitis and gastritis, that is often fatal. A 49-year-old man unintentionally ingested approximately 100 mL (55%) of this compound in solution, which was purchased as plastic hardener. Despite resuscitation, he died about 11 hours after admission. We report a patient with poisoning due to methyl ethyl ketone peroxide who presented with corrosive esophagitis and gastritis, gastrointestinal bleeding, and developed ischemia of the bowel and necrosis of the liver and died of severe metabolic acidosis and multiorgan failure...

Volvulus of the intestines may involve either the small bowel or colon. In the pediatric population, small bowel volvulus is more common, while in the adult population, colonic volvulus is more often seen. The two most common types of colonic volvulus include sigmoid and cecal volvulus. Prompt diagnosis and treatment is imperative, otherwise bowel ischemia may ensue. Treatment often involves emergent surgical exploration and bowel resection.

Spinal cord stimulation (SCS) is well known for its early role in the management of chronic pain, mainly failed back surgery syndrome (FBSS), spasticity, and bowel and bladder dysfunction. In more recent years, SCS has been proposed for patients suffering from refractory angina or peripheral vasculopathies in order to gain symptom relief, thus indicating some hemodynamic effect on the peripheral circulation. Taking into account this scientific observation, since the late1980s, researchers have started to investigate the potential effect of SCS on cerebral blood flow (CBF) regulation and its possible application in certain pathological settings dealing with vascular pattern dysfunction, such as ischemia, subarachnoid hemorrhage, head trauma, and brain tumors...
