In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...

INTRODUCTION: Insufficient microvascular oxygenation (μHBO2) of the intestinal mucosa worsens outcome of septic patients. Hypercapnia ameliorates μHBO2, mediated via endogenous vasopressin release. Under physiological conditions, blockade of the endogenous sympathetic nervous system abolishes this protective effect of hypercapnia. The aim of our study was therefore to evaluate the role of the endogenous sympathetic nervous system during hypercapnia on intestinal μHBO2 under septic conditions...

A 48-year-old woman was admitted with 15-mo history of abdominal pain, diarrhea and hematochezia, and 5-mo history of defecation difficulty. She had been successively admitted to nine hospitals, with an initial diagnosis of inflammatory bowel disease with stenotic sigmoid colon. Findings from computed tomography virtual colonoscopy, radiography with meglumine diatrizoate, endoscopic balloon dilatation, metallic stent implantation and later overall colonoscopy, coupled with the newfound knowledge of compound Qingdai pill-taking, led to a subsequent diagnosis of ischemic or toxic bowel disease with sigmoid colon stenosis...

BACKGROUND: Tetrahydrobiopterin (BH4), an endogenous nucleic acid derivative, acts as an important cofactor for several enzymes found within the vascular endothelium, which is deranged in sepsis. OBJECTIVE: We hypothesized that BH4 would improve capillary density and decrease inflammation within the intestinal microcirculation of septic rats. METHODS: We conducted a randomized, controlled trial using two previously validated models of sepsis in rats: 1) A fecal peritonitis model using a stent perforating the ascending colon, and 2) An endotoxemia model using lipopolysaccharide (LPS) toxin from E...

We report a case of an 81-year-old man, hospitalized for sepsis unresponsive to targeted antibiotic therapy, who underwent abdominal aortic aneurysmectomy with stent placement before 12 years. Point-of-care ultrasound examination showed the presence of a voluminous and inhomogeneous lesion adjacent to the anterior wall of aortic bifurcation with pulsatile flow from the aorta into the lesion, highlighted by Color-Doppler, and peripheral (closely with intestinal loops) floating hyperechoic spots marked by posterior comet tail artifact, suggestive for the presence of air bubbles...

RATIONALE: Metastatic involvement of the gastrointestinal tract is an uncommon scenario encountered in the clinical practice. Our case represents a gastric outlet obstruction (GOO) as a consequence of distant Transitional cell carcinoma (TCC) metastasis without any lymph node involvement in association with inflammatory stranding leading to extrinsic duodenal obstruction. PATIENT CONCERNS: We report an unusual case of a 73-year-old male presented with a five-week history of nausea, vomiting and abdominal pain due to the metastatic extension from TCC that had been considered in remission...

Coil migration is an extremely rare but hazardous complication of aneurysmal coil embolization. Only 1 case report has described coil migration following endovascular exclusion to gastrointestinal (GI) tract. We report the experience of a case of colon penetration caused by embolization coil placed for internal iliac aneurysm. A 66-year-old man visited the Emergency Department for hematochezia that had persisted for 3 months. Stent insertion and coil embolization of left internal iliac artery aneurysm had been performed on the patient 18 months ago...

BACKGROUND AND AIMS: Self-expandable metallic stents are increasingly used in the treatment of obstructing colorectal cancer (CRC). Although endoscopic colonic stenting is widely accepted in palliation, disagreement exists about its role in a curative setting. This study aims to describe long-term survival data in a large patient group, treated with colonic stenting as a bridge to surgery (BTS) for CRC. PATIENTS AND METHODS: This prospective study included 97 patients who presented in a Belgian hospital between 1998 and 2013 with an obstructing, though potentially curable, CRC...

Self-expandable metal stents are often used to treat obstructive large bowel cancers. This study assessed the safety and efficacy of colonic stent insertion carried out in a district general hospital. Methods A retrospective review was carried out between 1 January 2007 and 28 February 2014 to identify patients who underwent stent insertion for malignant colorectal obstruction. Results Seventy-five patients (median age 75.2 years, 70.6% male) with primary colorectal cancer underwent stent insertion - 53 underwent semi-elective self-expanded metal stent insertion (for subacute bowel obstruction) and 22 had emergency stent inserted (for acute bowel obstruction)...

Video capsule endoscopy (VCE) has become the method of choice for visualizing the small bowel mucosa and is generally considered to be a safe method. Although uncommon, the most feared complication of VCE is capsule retention that can potentially lead to life-threatening bowel obstruction. Herein, we present for the first time a case of capsule retention in a colonic stent. The patient had known Crohn's disease with colonic involvement and underwent an uneventful but incomplete small bowel VCE for assessment of disease activity and extension for optimizing medical treatment...

BACKGROUND: Endothelial barrier dysfunction is a hallmark in the pathogenesis of sepsis. Sphingosine-1-phosphate (S1P) has been proposed to be critically involved in the maintenance of endothelial barrier function predominately by activating S1P receptor-1 (S1P1). Previous studies have shown that the specific S1P1 agonist SEW2871 improves endothelial barrier function under inflammatory conditions. However, the effectiveness of SEW2871 and potential side effects remained largely unexplored in a clinically relevant model of sepsis...

The therapeutic target in Crohn's disease (CD) has been raised to the achievement of mucosal healing. Although effective treatments that target cytokines and other molecules has been widely used for CD, intestinal strictures are still a major cause of surgery. Endoscopic balloon dilation (EBD) is known to be an effective and safe intervention for intestinal strictures in CD. Since frequent intestinal resection often results in short bowel syndrome and can decrease the quality of life, EBD can help avoid surgery...

Management of metastatic colorectal cancer requires accurate staging and multidisciplinary evaluation, leading to a consensus treatment plan with the ultimate goal of increasing survival and improving the quality of life, while taking into consideration the patient's performance status, disease burden, and goals of care. Since the introduction of multidrug chemotherapeutic regimens, survival of patients with metastatic colorectal cancer has improved. Many patients with unresectable disease are undergoing surgery for asymptomatic primary tumors despite evidence that it is usually a futile intervention...

Many colorectal carcinomas will present emergently with issues such as obstruction, perforation, and bleeding. Emergency surgery is associated with poor short- and long-term outcomes. For abnormality localizing to the colon proximal to the splenic flexure, surgical management with hemicolectomy is often a safe and appropriate approach. Obstructions are more common in the distal colon, however, where there is an evolving spectrum of surgical and nonsurgical options, most notably by the development of endoluminal stents...

The prevalence of acute colorectal obstruction at the hospital setting is high. There is need for improvement in the quality of colonoscopy for relieving obstruction. A retrospective, uncontrolled, open-label study was conducted, with the aim of documenting the causes of acute colorectal obstruction and the quality of colonoscopy practice in managing obstruction at a university hospital in China. A total of 61 adult patients with acute colorectal obstruction treated with urgent colonoscopy between February, 2011 and January, 2016 were identified at the Endoscopic Unit of Tongji Hospital (Wuhan, China)...

BACKGROUND: Traditionally, all patients with a malignant obstruction of the proximal colon (MOPC) are treated with emergency resection. However, recent data suggest that Self-expandable metallic stent (SEMS) placement could lower mortality and morbidity rates. This study therefore aimed to compare SEMS placement with emergency resection as treatment options for MOPC. METHODS: All consecutive patients that underwent SEMS placement for MOPC in the period 2004-2015 at our institution were identified...
