Chronic intestinal pseudo-obstruction is a disorder of gut motility resulting in severe abdominal pain, bloating, nausea, and vomiting after eating. The avoidance of food in order to minimize symptoms causes malnutrition. To date, no medical or surgical treatment has been shown to be of lasting benefit. We treated 10 patients disabled by chronic intestinal pseudo-obstruction using home parenteral nutrition. All were rendered minimally symptomatic as long as they refrained from significant oral intake. Nine of the 10 patients were malnourished prior to the institution of treatment. Home parenteral nutrition increased mean total body weight from 74.7 +/- 2.9 to 93.5 +/- 3.7% (p less than 0.001), mean lean body mass from 78.4 +/- 6.5 to a mean of 92.7 +/- 2.6 (p less than 0.02), and mean body fat from 57.1 +/- 8.8 to 83.8 +/- 8.2% of expected values (p less than 0.05). Mean total body potassium increased from 68.8 +/- 13.1 to 80.5 +/- 10.7 g (p less than 0.05). We conclude that in chronic intestinal pseudo-obstruction, home parenteral nutrition coupled with minimal oral intake effectively relieves symptoms and significantly improves the nutritional depletion.

Chronic intestinal pseudo-obstruction is the term applied to a heterogeneous group of functional motility disorders sharing a common clinical expression: signs and symptoms of bowel obstruction in absence of mechanical occlusion. It is caused by ineffective intestinal propulsion. The chronic form of intestinal pseudo-obstruction may be primary or secondary. Primary pseudo-obstruction or chronic idiopathic pseudo-obstruction (CIIP) defines a group of propulsive disorders having no recognized underlying diseases. This study presents four female patients, aged between 4 months to 7 years, and makes a review of the literature. The symptoms, very similar in three of them, were bilious vomiting, abdominal distention and constipation, alternating with diarrhea and malnutrition. The fourth patient, different from the others in the age of onset and evolution, only had severe constipation and abdominal bloating. The diagnostic was made by full thickness biopsies during laparotomy, getting specimens by mapping, at different heights of intestine and stomach. Samples were studied by optic and electronic microscopy and visceral myopathies were found. None of them had urinary disorders. Medical treatment consisted of total parental nutrition and/or enteral nutrition. Cisapride was not effective in the two patients who received it.

We report a 56-year old female with mitochondrial neurogastrointestinal encephalomyopathy (MNGIE), presenting with protein-losing gastroenteropathy and serum copper deficiency. There was no neuromuscular disease in her family members. Three years prior to admission, she developed severe gastrointestinal symptoms including diarrhea, nausea, vomiting and ascites, and was diagnosed as having protein-losing gastroenteropathy based on alpha(1)-antitrypsin clearance and other tests. She was referred to our department when neurological symptoms were apparent. Neurological examinations revealed bilateral ptosis, ophthalmoplegia, hearing loss, facial and limb muscle weakness, mild sensory deficit of vibration on her feet and hypoactive deep tendon reflexes. Pigmentary retinopathy, cerebellar ataxia and heart block were not seen. Serum copper level was decreased to 45 micrograms/dl (normal: 83-155). Chronic intestinal pseudo-obstruction was proven by X-ray studies, and diffuse leukoencephalopathy demonstrated on brain MRI. On EMG, motor nerve conduction velocities were prolonged with temporal dispersion. Her muscle biopsy from biceps brachii muscle showed both neuropathic and myopathic changes, scattered ragged-red fibers and focal cytochrome c oxidase deficiency. Southern blot and polymerase chain reaction analysis on mitochondrial DNA showed no deletions nor point mutations. The clinical and pathologic findings of the present patient fulfilled the diagnostic criteria of mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) proposed by Hirano et al. There are few reported patients with MNGIE in Japan, but none presented with protein-losing gastroenteropathy and serum copper deficiency. Since the copper is a cofactor of cytochrome c oxidase, decreased serum copper level may aggravate the respiratory chain enzyme metabolism in mitochondria. Therefore, treatment for gastrointestinal tract disturbance and copper administration may be necessary to prevent disease progression.

Chronic intestinal pseudo-obstruction (CIPO) is a disease characterized by episodes resembling mechanical obstruction in the absence of organic, systemic, or metabolic disorders. Pseudo-obstruction is an uncommon condition and can result from primary (40%) or secondary (60%) causes. The most common symptoms are nausea, vomiting, abdominal distension, abdominal pain and constipation or diarrhea. These symptoms are usually present many years before CIPO diagnosis. They can lead to severe electrolyte disorders and malnutrition. Principles for management of patients with CIPO are: to establish a correct clinical diagnosis in excluding mechanical obstruction; to perform a symptomatic and physiologic assessment of the gastrointestinal tract involved; to look for extra-intestinal manifestations, especially for myopathy and neuropathy; to discuss in some cases a surgery for full-thickness intestinal biopsies, and/or a neuromuscular biopsy in case of mitochondrial cytopathy suspicion. The management is primarily focused on symptom control and nutritional support to prevent weight loss and malnutrition. Treatment of CIPO includes prokinetic agents which may help to reduce gastrointestinal symptoms Courses of antibiotics may be needed in patients with symptoms suggestive of bacterial overgrowth. When necessary, enteral nutrition is preferred. In carefully selected patients, feeding jejunostomy with or without decompression gastrostomy may be tried. Long term parenteral nutrition should be reserved for patients who can not tolerate enteral nutrition. Intestinal transplantation can be discussed in selected patients.

Intestinal pseudo-obstruction is a rare motility disorder with symptoms and clinical signs of bowel obstruction without a mechanical cause. Symptoms might be acute or chronic. The pathogenesis of acute colonic pseudo-obstruction (Ogilvie's syndrome) is likely to result from an imbalance of the autonomic regulation of the colon. Chronic intestinal pseudo-obstruction (CIPO) may be congenital or acquired. A variety of underlying pathologies, e.g. visceral neuropathy or visceral myopathy are known. Main symptoms are abdominal pain, vomiting, constipation or diarrhoea. Mechanical obstruction, ischemia and perforation should be excluded. Supportive therapy, medical therapy or an intervention (endoscopy, surgery) might be necessary in Ogilvie's syndrome depending on ceacal diameter and duration of distension. Treatment of CIPO depends on the severity of the disease and often needs a multidisciplinary approach.

Chronic intestinal pseudo-obstruction (CIP) is an infrequent complication of an active systemic lupus erythematosus (SLE). We illustrate a case of SLE inactive-related CIP. A 51-year old female with inactive SLE (ECLAM score 2) was hospitalized with postprandial fullness, vomiting, abdominal bloating and abdominal pain. She had had no bowel movements for five days. Plain abdominal X-ray revealed multiple fluid levels and dilated small and large bowel loops with air-fluid levels. Intestinal contrast radiology detected dilated loops. CIP was diagnosed. The patient was treated with prokinetics, octreotide, claritromycin, rifaximin, azathioprine and tegaserod without any clinical improvement. Then methylprednisolone (500 mg iv daily) was started. After the first administration, the patient showed peristaltic movements. A bowel movement was reported after the second administration. A plain abdominal X-ray revealed no air-fluid levels. Steroid therapy was slowly reduced with complete resolution of the symptoms. The patient is still in a good clinical condition. SLE-related CIP is generally reported as a complication of an active disease. In our case, CIP was the only clinical demonstration of the SLE.

Chronic intestinal pseudo-obstruction (CIP) is a rare and serious disorder of the gastrointestinal (GI) tract characterized as a motility disorder with the primary defect of impaired peristalsis; symptoms are consistent with a bowel obstruction, although mechanical obstruction cannot be identified. CIP is classified as a neuropathy, myopathy, or mesenchymopathy; it is a neuropathic process in the majority of patients. The natural history of CIP is generally that of a progressive disorder, although occasional patients with secondary CIP note significant symptomatic improvement when the underlying disorder is identified and treated. Symptoms vary from patient to patient depending on the location of the luminal GI tract involved and the degree of involvement; however, the small intestine is nearly always involved. Common symptoms include dysphagia, gastroesophageal reflux, abdominal pain, nausea, vomiting, bloating, abdominal distension, constipation or diarrhea, and involuntary weight loss. Unfortunately, these symptoms are nonspecific, which can contribute to misdiagnosis or a delay in diagnosis and treatment. Since many of the symptoms and signs suggest a mechanical bowel obstruction, diagnostic tests typically focus on uncovering a mechanical obstruction, although routine tests do not identify an obstructive process. Nutrition supplementation is required for many patients with CIP due to symptoms of dysphagia, nausea, vomiting, and weight loss. This review discusses the epidemiology, etiology, pathogenesis, diagnosis, and treatment of patients with CIP, with an emphasis on nutrition assessment and treatment options for patients with nutrition compromise.

Chronic intestinal pseudo-obstruction is a known complication of patients with systemic sclerosis, manifested as nausea, vomiting, constipation, abdominal distension and pain. We report a series of cases with systemic sclerosis that presented with signs of intestinal obstruction. In all cases, the differentiation between a pseudo-obstruction and true mechanical obstruction remained a formidable challenge. Our goal was to present different scenarios of patients with systemic sclerosis and features of intestinal obstruction, with a review on its clinical approach.

Case summary A 7-year-old neutered male Persian cat was presented for acute vomiting and inappetence. Physical examination revealed severe abdominal distension. Radiographs demonstrated pneumoperitoneum, megaoesophagus and generalised gaseous distension of the digestive tract. Exploratory coeliotomy was performed, revealing markedly distended and thickened small and large intestines with no observable peristalsis. No intestinal perforation was present. Bacteriological and cytological analysis of abdominal fluid revealed a septic peritonitis involving Pasteurella multocida. Full-thickness intestinal biopsies demonstrated lymphocytic ganglioneuritis localised to the enteric nervous system, in association with glandular atrophy and muscular layer hypertrophy. Amoxicillin-clavulanate and analgesics were given. The cat's general condition gradually improved after the addition of pyridostigmine bromide (0.5 mg/kg q12h PO), initiated 3 days postsurgery. Vomiting resolved and did not recur. Follow-up radiographs at 15 days, and 1 and 6 months showed persistent intestinal ileus, milder than on the pretreatment radiographs. Thirty months after presentation the cat is still alive, without clinical signs, and receives 1 mg/kg q12h pyridostigmine. Relevance and novel information To our knowledge, this is the first case of ganglioneuritis of the myenteric plexus described in cats, as well as the first one successfully treated with pyridostigmine. Chronic intestinal pseudo-obstruction is a very rare condition in cats but should be included in the differential diagnosis of generalised gastrointestinal ileus.

Chronic intestinal pseudo-obstruction (CIPO) is an uncommon disorder characterized by the presence of bowel dilatation and abnormal motility. It is an important cause of chronic intestinal failure in patients with systemic sclerosis (SSc). Although intestinal pseudo-obstruction is an infrequent reason for hospitalization in these patients, it has been correlated with high in-hospital mortality compared to SSc patients hospitalized for other reasons as well as patients with intestinal pseudo-obstruction arising from other causes. Patients present with signs and symptoms of mechanical bowel obstruction, such as nausea, vomiting, constipation, abdominal pain, and abdominal distension, in the absence of an anatomic lesion blocking the movement of intestinal contents. Despite breakthroughs in our understanding of this disorder, these patients continue to be treated largely with organ-based symptomatic therapy. Unfortunately, despite treatment, they often experience decreased quality of life and impairment in their everyday lives. Here, we present an interesting case of an individual with SSc for many years who presented with signs and symptoms of CIPO.
