Dr Mohamed Saber and Dr Gagandeep Singh et al. Colonic pseudo-obstruction (also known as Ogilvie syndrome) is a potentially fatal condition leading to an acute colonic distention without an underlying mechanical obstruction. It is defined as an acute pseudo-obstruction and dilatation of the colon in the absence of any mechanical obstruction Pseudoobstruction of the colon is often mistaken, both clinically and radiologically, for other abnormal conditions, such as mechanical obstruction and paralytic ileus. This error may occur because colonic pseudoobstruction is a relatively unknown entity that has received scarce attention in the radiologic literature Colonic pseudoobstruction can be diagnosed on the basis of CT findings that show extensive colonic dilatation without an obstructive lesion at the intermediate transitional zone or adjacent to the splenic flexure
Intestinal pseudo-obstruction is characterized by the dilation of bowel in the absence of an anatomical obstruction. Patients present with the signs and symptoms of bowel obstruction, including nausea, vomiting, abdominal distension, and obstipation with bowel dilation on x-ray or CT imaging. Pseudo-obstruction can be acute or chronic Laboratory investigations generally are of little diagnostic value for intestinal pseudo-obstruction (also referred to as acute colonic pseudo-obstruction [ACPO] or Ogilvie syndrome]). The.. Colon is dilated. May have multiple, long fluid levels. The cecum should not exceed 12-15 cm in diameter due to risk of perforation. CT is helpful in excluding a cause of a large bowel obstruction or perforation. Differential Diagnosis. Large bowel obstruction. No point of obstruction in colonic pseudo-obstruction. Constipation
Pseudo-obstruction is characterized by signs and symptoms of a mechanical obstruction of the small or large bowel in the absence of a mechanical cause. Pseudo-obstruction may be acute or chronic and is characterized by the presence of dilation of the bowel on imaging. Other causes of colonic distension including toxic megacolon, mechanical. These abnormal bowel gas patterns will appear the same whether imaged initially by conventional radiography or by CT scanning. CT is superior in revealing the location, degree, and cause of an obstruction and in demonstrating any signs of reduced bowel viability. Abnormalities of bowel function are suspected by the history and clinical findings Acute colonic pseudo-obstruction is the clinical syndrome of acute large bowel dilatation without mechanical obstruction that is an important cause of morbidity and mortality. Acute colonic pseudo-obstruction occurs in hospitalized or institutionalized patients with serious underlying medical and su
Abstract Objectives: To document intestinal pseudo-obstruction (IpsO) as a recognised clinical manifestation of systemic lupus erythematosus (SLE) and a possible new clinical entity with its apparent association with ureterohydronephrosis Intestinal pseudo-obstruction is characterized by the dilation of bowel in the absence of an anatomical obstruction. Patients present with the signs and symptoms of bowel obstruction, including nausea, vomiting, abdominal distension, and obstipation with bowel dilation on x-ray or CT imaging Chronic intestinal pseudo-obstruction (CIPO) is a rare, potentially debilitating gastrointestinal (GI) condition characterized by symptoms of intestinal obstruction with the absence of anatomic lesions
may occur because colonic pseudoobstruction is a relatively unknown entity that has received scarce attention in the radiologic literature. Our purpose was to describe the imaging fea - tures of colonic pseudoobstruction and to dis - cuss the pathologic findings. Materials and Methods Patients A computerized search of electronic medica Abdominal X-ray may demonstrate the level of obstruction. Abdominal X-ray cannot reliably differentiate mechanical obstruction from pseudo-obstruction. The most common causes of large bowel obstruction are colo-rectal carcinoma and diverticular strictures. Less common causes are hernias or volvulus (twisting of the bowel on its mesentery)
Pseudo-obstruction; Constipation; Imaging Findings. Contrast-enhanced conventional radiography (i.e. barium studies) are usually used to image GI scleroderma; Esophagus; Dilated, hypomotile esophagus specially involving distal 2/3; Patulous esophagogastric junctio After abdominal radiology that shows the presence of a neonatal high intestinal obstruction, an upper gastrointestinal series is typically performed for further evaluation. However, neonates with classic radiographic findings of high intestinal obstruction, such as duodenal atresia, may directly undergo surgery without any additional imaging study Motility disorders of the esophagus are an important cause of esophageal complaints, especially when symptoms are not readily explained by a structural abnormality. An understanding of esophageal anatomy and physiology is required for proper radiographic evaluation of normal and abnormal esophageal function However, in all situations of large bowel obstruction, no matter how clear the diagnosis appears on plain radiology, a water-soluble contrast enema 13, 14 or computed tomography (CT) 41 should be performed to differentiate mechanical obstruction from pseudo-obstruction. No direct comparison has been made between these two imaging modalities in. Table 64-7. Intestinal Pseudo-Obstruction: Ogilvie's Syndrome. Table 64-8. Colon Distention Without Obstruction.

From the Departments of Medicine and Radiology, University of Washington School of Medicine, and from the Departments of Medicine of the U.S. Public Health Service Hospital and Veterans Administration Hospital, Seattle, WA Pseudo-obstruction may be acute or chronic and is characterized by the presence of colonic dilatation on imaging. The historic name Ogilvie syndrome has since fallen out of use. In many cases, acute colonic pseudo-obstruction (ACPO) is precipitated by an underlying condition 1 such as electrolyte disturbance, trauma, sepsis and cardio. Pseudo-obstruction in this disease is a better known phenomenon (9-12). The simultaneous occurrence of these findings has not yet been reported. During the years 1964 to 1967, three unusual cases of generalized scleroderma with both pneumatosis and pseudo-obstruction were seen at the University of Colorado Medical Center Chronic intestinal pseudo-obstruction (CIPO) is a severe digestive syndrome characterized by derangement of gut propulsive motility which resembles mechanical obstruction, in the absence of any obstructive process. Although uncommon in clinical practice, this syndrome represents one of the main causes of intestinal failure and is characterized.
Introduction. Chronic intestinal pseudo-obstruction (CIPO) is a rare and severe functional digestive syndrome, characterized by a disorder of gut propulsive motility affecting the structure and/or function of components of the intestinal neuromusculature that mimics a mechanical obstruction , , , .It was first described in 1958 by Dudley et al. who reported 13 patients with bowel occlusion's. Ileus and pseudo-obstruction both refer to intestinal dysmotility syndromes that have symptoms, signs, and the radiologic appearance of bowel obstruction in the absence of a mechanical cause. There has been nomenclatural confusion because of the use of these two terms as synonyms; they are not. The term ileus is used when the contents of the small intestine are acutely unable to transit. 1. Ir J Med Sci. 1998 Jan-Mar;167(1):41-2. Colonic pseudo-obstruction following acute pancreatitis.

Informed written consent was obtained from the patient for publication of this case report and accompanying images Chronic intestinal pseudo-obstruction (CIP) is a rare disorder of gastrointestinal motility where coordinated contractions (peristalsis) in the intestinal tract become altered and inefficient. Motility is the term used to describe the contraction of muscles in the gastrointestinal (GI) tract
Intestinal pseudo-obstruction is a rare complication of lupus that is often seen in association with ureterohydronephrosis and interstitial cystitis. This clinical syndrome is thought to be because of smooth muscle dysmotility of the gastrointestinal and genitourinary tracts, although the exact mechanism of dysmotility remains unknown Colonic Pseudo-obstruction. General Considerations. Mimics large bowel obstruction without point of obstruction; Mostly in those over 60, with a slight male predominance; Apparently due to autonomic nervous system imbalance leading to a dysfunctional distal colon and colonic ileus similar to Hirschsprung's diseas intestinal pseudo-obstruction refers to a heterogeneous group of conditions with impaired gastrointestinal propulsion, leading to signs and symptoms of intestinal obstruction in absence of any obstructive or occluding mechanical blockage 1,2,3; PubMed 29487492 Clinics in colon and rectal surgery Clin Colon Rectal Surg 20180301 31 2 99-107 99 intestinal pseudo-obstruction may be acute if.
Small-bowel obstruction is a fairly common cause of abdominal pain. Differentiating between true duodenal obstruction and pseudo obstruction is important given differing treatment strategies. Here, we present augmentation of a hepatobiliary scan with a small amount of oral liquids and delayed imaging to differentiate between these two entities DESCRIPTION. Chronic Idiopathic Intestinal Pseudo Obstruction (CIIPO) is a rare gastrointestinal motility (movement) disorder characterized by impairment of the muscle contractions that move food, fluid, stool or air through the gastrointestinal (digestive) tract in the absence of any mechanical obstructions or lesion (s) We suggest that these patients manifested a hereditary disorder with distinctive clinical, radiological, and neuropathological features, and propose the acronym POLIP to emphasize the distinctive tetrad of polyneuropathy, ophthalmoplegia, leukoencephalopathy, and intestinal pseudo-obstruction. PMID: 2173474 [Indexed for MEDLINE] Publication Types Ogilvie Syndrome. Also known as Acute Colonic Pseudo Obstruction, Ogilvie syndrome is a potentially fatal clinico-radiological conditon with features akin to large bowel obstruction without any mechanical obstruction. It is most commonly seen in elderly and usually unwell patients, with multiple probable or causative factors like electrolyte.
Menys A, Butt S, Emmanuel A, et al. Comparative quantitative assessment of global small bowel motility using magnetic resonance imaging in chronic intestinal pseudo-obstruction and healthy controls This is an example of colonic pseudo-obstruction, also known as Ogilvie syndrome. This condition is generally seen in patients over the age of 60 and has similar clinical and radiographic features to true large bowel obstruction, except that no actual mechanical obstruction is present. It is caused by an imbalance in the autonomic nervous system Intestinal pseudo-obstruction (IPO) is a clinical syndrome characterized by impaired intestinal motility as a result of dysfunction of the visceral smooth muscle or the enteric nervous system. IPO may be the initial presentation of SLE and usually occurs in the setting of active lupus. 25 The small bowel is more commonly involved than the large. 1 Introduction. Acute colonic pseudo-obstruction, also known as Ogilvie's syndrome, was first described in 1948 and refers to massive dilation of the colon without underlying mechanical obstruction or other organic cause. The pathophysiologic basis of Ogilvie's syndrome remains unclear but is believed to be due to a functional disturbance in the enteric nervous, leading to an adynamic colon. Large bowel diameter ≥5-6cm is associated with obstruction. CT. Can usually identify the cause of obstruction, except in cases of pseudo-obstruction. Sensitivity for diagnosing large bowel obstruction as high as 90% (not as high as for small bowel obstruction) Can also diagnose intestinal ischemia. Colonoscopy
Gastric outlet obstruction is defined as any process that impedes emptying of the stomach. Its causes are similar to those of intestinal obstruction - functional and mechanical. Diabetic gastroparesis and ileus/pseudo-obstruction are functional causes of obstruction. Mechanical causes can be divided into benign and malignant Treatment for pseudo-obstruction. If your doctor determines that your signs and symptoms are caused by pseudo-obstruction (paralytic ileus), he or she may monitor your condition for a day or two in the hospital, and treat the cause if it's known. Paralytic ileus can get better on its own Ogilvie's syndrome is a rare postoperative condition commonly referred to as a colonic pseudo-obstruction due to the absence of mechanical obstruction. It should be a differential for patients over the age of 60 years who present with nausea, vomiting, and colonic dilatations on imaging. Ogilvie's syndrome following a ventriculoperitoneal (VP) shunt placement is an extremely rare.

Chronic intestinal pseudo-obstruction is a rare disorder that affects the motility of the gastrointestinal tract. It results in acute or subacute intestinal obstruction symptoms in the absence of mechanical lesion. It can lead to intestinal failure in children with significant strain on nutrition, growth, and development. There is no universally agreed protocol for management of chronic.

Radiology. 2000;216(1):178-9. [PMID: 10887245] The term colonic pseudo-obstruction describes a condition in which symptoms of bowel obstruction are present without any mechanical cause that would prevent further passage along the gastrointestinal (GI) tract. This can be seen as acute and sometimes massive dilation of the colon, and it often. Magnetic resonance imaging. Dynamic magnetic resonance imaging (MRI) of gastrointestinal motility has evolved and shows promise for clinical assessment of gastric, small intestinal, and colonic motility in patients with inflammatory bowel disease, pseudo-obstruction, and functional bowel disorders.  Its advantages include it being a quick, noninvasive imaging modality; the absence of. Synonyms for Pseudo-obstruction in Free Thesaurus.

Ogilvie syndrome is a rare, acquired disorder characterized by abnormalities affecting the involuntary, rhythmic muscular contractions (peristalsis) within the colon. Peristalsis propels food and other material through the digestive system through the coordination of muscles, nerves and hormones. The colon is often significantly widened (dilated)
Chronic Intestinal Pseudo-Obstruction. Diagnostic Test: MRI scans after a liquid meal. Detailed Description: People with chronic intestinal pseudo-obstruction (CIPO) have problems digesting their food properly, due to a problem in their gut nerves or muscle. There are not many good tests to assess how a patient's stomach and bowels are working Three new cases are presented of a recently described entity of idiopathic intestinal pseudo-obstruction. All the patients were young females who had undergone multiple laparotomies for suspected mechanical intestinal obstruction. Extensive clinical and histologic examinations failed to reveal a systemic cause

contexts. Occasionally, patients may present to the hospital with an initial presentation caused by colonic pseudo-obstruction.; More commonly, colonic pseudo-obstruction develops as a nosocomial complication.. For example, As a post-operative complication (especially following orthopedic or gastrointestinal surgery, with prolonged immobility) A 63-year-old man had recently undergone subtotal oesophagectomy for squamous carcinoma of the oesophagus. He had undergone a Heller's myotomy for achalasia of the oesophagus 30 years previously. A.. Acute gastrointestinal (GI) immune-related adverse events (irAE) are commonly reported by patients with cancer undergoing treatment with immune checkpoint inhibitors (CPI); however chronic irAEs are rare. We present a case of a 71-year-old woman with metastatic gastro-oesophageal junction (GOJ) adenocarcinoma who developed delayed-onset chronic intestinal pseudo-obstruction (CIPO) while. Chronic intestinal pseudo-obstruction (CIPO) belongs to a heterogeneous group of rare, severe, and potentially life-threatening disorders characterized by recurrent or chronic symptoms and signs of intestinal obstruction in the absence of any mechanical obstruction .It is characterized by profound impairment of gastrointestinal motility due to a variety of disorders affecting the enteric. colonic pseudo-obstruction by using the keyword(s) endoscopy, colon volvulus, gastrointestinal endoscopy, acute colonic pseudo-obstruction, sigmoid volvulus, endoscopic procedures, and procedures.

Intestinal pseudoobstruction represents intestinal dysmotility rather than obstruction. Pseudoobstruction is a chronic illness, sometimes with remissions and relapses, and is far rarer than acute ileus. Enteroclysis radiographic studies may be necessary to confirm the absence of partial obstruction Intestinal pseudo-obstruction is a condition in which there are symptoms of blockage of the intestine (bowels) without any physical blockage. The digestive system organs in the abdominal cavity include the liver, gallbladder, stomach, small intestine and large intestine
Imaging tests. These may include an abdominal ultrasound or CT scan. Your healthcare provider will rule out other causes of your symptoms. He or she will check you for an ulcer, inflammation of your gallbladder, and pancreatic cancer. Your healthcare provider can often confirm a pseudocyst with CT or with another imaging test, such as MRI Radiology. 2015 Jun. 275(3):651-63. [Medline] .

Radiological imaging studies. Abdominal radiograph (A-C) showed an evolution of intestinal pseudo-obstruction involving both small and large bowels (radiograph performed on admission, day 5, and 10, respectively); computed tomography abdomen and pelvis (D) and (E) showed dilated, fluid-filled stomach and small bowel loops; (F) very distended. The clinical and radiological features of acute large-bowel pseudo-obstruction occurring in 13 patients over a 7-year period are reviewed. Clinical features included atypical signs and symptoms of large-bowel obstruction and serious concomitant illness, including trauma in 10 Ogilvie syndrome (not Oglivie) is a condition where there is a sudden blockage of the colon despite there being no mechanical reason for the obstruction. This means that there is no mass or narrowing causing the obstruction. In fact, the colon is actually widened (dilatation) abnormally. Ogilvie syndrome is also known as acute colonic pseudo. Chronic intestinal pseudo-obstruction (CIP) is a disorder in which motility is compromised, and the contractions are uncoordinated and inefficient. When this happens, digestion is not normal, and the intestine may not absorb enough nutrition. The term pseudo-obstruction refers to a group of gastrointestinal disorders that have similar.
