Colonoscopy is one of the most widely used procedures in medical practice for the diagnosis and treatment of many benign and malignant diseases of the colorectal tract. Colonscopy has become the reference procedure for screening and surveillance of colorectal cancer. The overall rate of adverse events is estimated to be about 2.8 per 1,000 procedures, while complications requiring hospitalization are about 1.9 per 1,000 colonoscopies. Mortality from all causes and colonoscopy-specific mortality are estimated to be 0...

We report a 41-year-old woman who developed histology- and colonoscopy-proven ischemic colitis with the use of naratriptan not exceeding the maximum 2 doses a day and 3 days per week and without a known medical or cardiovascular history. By exclusion of other causes of colonic ischemia, naratriptan was considered the sole causal agent. Discontinuation of naratriptan resulted in a complete clinical recovery. To date, our patient is the youngest known patient to develop ischemic colitis on isolated naratriptan in the setting of no known medical risk factors or predisposing medical condition...

Knowledge about the role of farnesoid X receptor (FXR) in the intestine is rapidly expanding. In pre-clinical animal models of inflammatory bowel disease and bile duct ligation, FXR activation has proven to directly target the three pillars of intestinal homeostasis: intestinal permeability, inflammation and bacterial translocation. The protective role of FXR-ligands on this homeostasis has implications for many intestinal pathologies like inflammatory bowel disease, ischemia reperfusion injury, the metabolic syndrome, colon cancer and even diarrhea...

Open surgical repair of an aortic aneurysm requires aortic cross-clamping, resulting in temporary ischemia of all organs and tissues supplied by the aorta distal to the clamp. Major complications of open aneurysm repair due to aortic cross-clamping include renal ischemia-reperfusion injury and postoperative colonic ischemia in case of supra- and infrarenal aortic aneurysm repair. Ischemia-reperfusion injury results in excessive production of reactive oxygen species and in oxidative stress, which can lead to multiple organ failure...

BACKGROUND: Mesenteric venous thrombosis (MVT) is a relatively uncommon but potentially lethal condition associated with bowel ischemia and infarction. The natural history and long-term outcomes are poorly understood and under-reported. METHODS: A single-institution retrospective review of noncirrhotic patients diagnosed with MVT from 1999 to 2015 was performed using International Classification of Diseases, Ninth Revision and radiology codes. Patients were excluded if no radiographic imaging was available for review...

BACKGROUND: Gastrointestinal side effects are particularly common with clozapine and occur with other antipsychotics, ranging from mild constipation to fatal bowel obstruction and/or ischemia. While this adverse-effect spectrum has been attributed to 'gastrointestinal hypomotility', gastrointestinal transit times in antipsychotic-treated patients have not previously been measured, making this mechanism speculative. METHODS: Using standardized radiopaque marker ('Metcalf') methods we established colonic transit times of antipsychotic-treated psychiatric inpatients and compared them with population normative values...

INTRODUCTION: Acute mesenteric ischemia is the most severe gastrointestinal complication of acute aortic dissection. The timing of diagnosis is of major importance, in fact the recognition of acute mesenteric ischemia often occurs too late due to the presence of unspecific symptoms and lack of reliable exams. Recently, indocyanine green fluorescence angiography has been adopted in order to measure blood perfusion and microcirculation. PRESENTATION OF CASE: We decided to perform a diagnostic laparoscopy with the support of intra-operative near-infrared indocyanine green fluorescence angiography, in order to detect an initial intestinal ischemia in a 68-year-old patient previously treated with a TEVAR procedure for a type-B aortic dissection...

Ramucirumab is an antiangiogenesis agent targeting the vascular endothelial growth factor receptor-2 (VEGFR-2), approved to treat advanced gastric and colon cancer. In clinical trials, it was shown to cause a small increase in arterial thromboembolism compared to placebo, including cerebral and myocardial ischemia, which was not statistically significant. Detailed case reports are lacking and we here present one of the first case reports of stroke secondary to ramucirumab-induced in situ thrombosis.

INTRODUCTION: Pneumatosis intestinalis is one of serious conditions following mechanical bowel obstruction. Emergency surgery is generally required to be a definite treatment in these patients of pneumatosis intestinalis, because of its risk of bowel ischemia and perforation. Since the operation in unprepared colon usually resulted in unfavorable outcome, the use of colonic stent is considered one of potential options as a bridge to definitive surgery. Presently, there is no widely published report of using colonic stent in these patients, particularly for stepping to curative surgery...

Ischemia causes severe damage in the gastrointestinal tract. Therefore, it is interesting to study how the barrier and transport functions of intestinal epithelium change under hypoxia and subsequent reoxygenation. For this purpose we simulated hypoxia and reoxygenation on mucosa-submucosa preparations from rat distal colon in Ussing chambers and on isolated crypts. Hypoxia (N2 gassing for 15 min) induced a triphasic change in short-circuit current (Isc): a transient decrease, an increase and finally a long-lasting fall below the initial baseline...

Standard endovascular repair of iliac/aortoiliac pathologies can lead to complications, such as buttock claudication, colon ischemia and erectile dysfunction. Branch grafts have been developed but require at least 6 weeks for customization and are not currently available in China; they are also quite expensive. To our knowledge, modified fenestrated stent grafts (MFSGs) are a safe and effective alternative for treating patients with juxtarenal aneurysms. Most MFSGs are used for the preservation of renal and left subclavian arteries...

Carbon monoxide (CO) poisoning is common, but it has rarely been reported to cause ischemic colitis. In this case, a 34-year-old female with depression presented to an emergency department after a period of unconsciousness, with urinary and bowel incontinence, following exposure to car exhaust. Her carboxyhemoglobin level was 23%. She had metabolic acidosis. She was transferred to our facility for hyperbaric oxygen treatment, where she had intractable nausea/vomiting with abdominal pain and bright-red bleeding per rectum...

Weight-loss medications have been associated with many conditions, including valvular heart disease, ischemic colitis, and pulmonary hypertension. There is a constant increase in the use of these drugs, especially new medications with better efficacy. Phentermine is one such drug, approved for short-term use to lose weight. We report a case of ischemic colitis in a female patient linked to inappropriate phentermine intake. The patient presented with symptoms of severe abdominal pain and repeated bowel movement associated with rectal bleeding for two weeks...

An obstructed inguinal hernia is a common surgical emergency, which presents with a variety of contents like the small intestine, omentum, and colon. Intestinal knotting is a rare entity encountered in surgical practice; it occurs when one coil of intestine wraps around the other and eventually leads to complications such as intestinal obstruction, ischemia, and gangrene. Both conditions are considered surgical emergencies and should be dealt with through appropriate surgical measures forthwith. We report the case of an obstructed inguinal hernia, which, on exploration, showed an ileoileal knot as its content...
