Pseudo pseudo intestinal obstruction

A 47-year-old male patient without a documented past medical history was referred to Sanno Hospital because of constipation and abdominal pain, which he had had for more than 5 years. Abdominal X-ray and CT scan showed an enlarged ascending colon from the cecum to the transverse colon, without apparent mechanical obstruction. The patient was diagnosed with chronic idiopathic colonic pseudo-obstruction, and because his symptoms were resistant to medication, surgical treatment was required. Laparoscopic subtotal colectomy was performed without any complications...

Eosinophilic myenteric ganglionitis (EMG) is characterised by eosinophilic infiltration of the myenteric plexus. EMG has been rarely reported as a cause of chronic intestinal pseudo-obstruction (CIPO), and its histopathological features are not fully elucidated. We analysed seven patients with CIPO. Three of them were diagnosed with EMG and four patients were categorised as non-EMG. Clinicopathological features were similar in both groups. These features included subtle to mild lymphocytic infiltration at the myenteric ganglia/muscularis propria, loss of myenteric ganglions and interstitial cells of Cajal (ICC), and no significant findings in the mucosa...

Amyloidosis is a syndrome involving amyloid protein deposition in various organs, resulting in organ dysfunction. Symptoms of gastrointestinal amyloidosis are usually nonspecific, such as diarrhea and body weight loss. We, here, report a patient who presented to the hospital with simultaneous hematemesis, melena, and intestinal pseudo-obstruction, leading to a diagnosis of primary gastrointestinal amyloidosis based on computed tomography (CT) and endoscopic findings. CT showed diffuse wall thickening from the duodenum to the jejunum, jejunal dilation, and fluid accumulation throughout the gastrointestinal tract...

BACKGROUND: Gastrointestinal hypomotility in people taking clozapine is common, poorly understood and potentially dangerous. It causes distress and sometimes sudden death, with greater associated morbidity than the better known adverse effect of clozapine, agranulocytosis. Neither the mechanism nor prevalence of clozapine-induced gastrointestinal hypomotility is well understood. Previous studies show clozapine impedes colon transit, likely owing to anticholinergic and anti-serotonergic properties...

PURPOSE: Acquired isolated hypoganglionosis (A-IH) is a late-onset intestinal pseudo-obstruction disorder and shows different pathophysiological findings from congenital isolated hypoganglionosis (C-IH). In this study, we retrospectively examined five cases of A-IH and investigated the features of A-IH. METHODS: Five cases of A-IH were extracted from a nationwide retrospective cohort study in 10 years, from which totally 355 cases of Allied Disorders of Hirschsprung's Disease (ADHD) were collected...

Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is an autosomal recessive disorder characterized by gastrointestinal dysmotility, cachexia, ptosis, peripheral neuropathy and leukoencephalopathy. The diagnosis is often not made until 5-10 years after the onset of symptoms. MNGIE is caused by mutations in thymidine phosphorylase gene TYMP. Here, we present a 19-year-old boy with MNGIE who had a chronic intestinal pseudo-obstruction, and we describe his family history. Genetic analysis revealed a novel homozygous c...

BACKGROUND: Inositol 1,4,5-trisphosphate receptors (IP3 Rs) are a family of intracellular Ca2+ release channels located on the membrane of endoplasmic reticulum, which have been shown to play critical roles in various cellular and physiological functions. However, their function in regulating gastrointestinal (GI) tract motility in vivo remains unknown. Here, we investigated the physiological function of IP3 R1 in the GI tract using genetically engineered mouse models. METHODS: Pdgfrb-Cre mice were bred with homozygous Itpr1 floxed (Itpr1f/f ) mice to generate conditional IP3 R1 knockout (pcR1KO) mice...

Mitochondrial diseases are rare, heterogeneous conditions affecting organs dependent on high aerobic metabolism. Presenting symptoms and signs vary depending on the mutation and mutant protein load. Diabetes mellitus is the most common endocrinopathy, and recognition of these patients is important due to its impact on management and screening of family members. In particular, glycemic management differs in these patients: the use of metformin is avoided because of the risk of lactic acidosis. We describe a patient who presented with gradual weight loss and an acute presentation of hyperglycemia complicated by the superior mesenteric artery syndrome...

Small bowel obstruction is common in emergency departments. However, the exact cause of intestinal pseudo-obstruction (IPO) is often misdiagnosed. IPO is considered a severe manifestation of systemic lupus erythematosus (SLE). However, IPO is rare as the initial manifestation of SLE. This paper reports a female patient who presented with IPO as the initial manifestation and was ultimately diagnosed with SLE. The 31-year-old female was definitively diagnosed with SLE after IPO symptoms for 1 month. She then presented multiple organ dysfunction syndrome (MODS) leading to a poor prognosis...

BACKGROUND & AIMS: Severe gastrointestinal dysmotility (GID) is a significant cause of chronic intestinal failure (CIF) with unclear benefits of sub-classifying into Chronic Intestinal Pseudo-obstruction (CIPO) and non-CIPO sub-types. We compared outcomes between CIPO and non-CIPO sub-types in a tertiary cohort of patients with CIF resulting from severe GID. METHODS: Adults with primary GID, commenced on home parenteral nutrition (HPN) over a 16-year period at a national referral centre, were included...

Gastrointestinal (GI) motility disorders are major contributing factors to functional GI diseases that account for >40% of patients seen in gastroenterology clinics and affect >20% of the general population. The autonomic and enteric nervous systems and the muscles within the luminal GI tract have key roles in motility. In health, this complex integrated system works seamlessly to transport liquid, solid, and gas through the GI tract. However, major and minor motility disorders occur when these systems fail...

A 59-year-old woman presented to our hospital with a 6-month history of nausea, weight loss, and abdominal distension. Physical examination revealed abdominal distension without tenderness, and edema, numbness, and multiple peripheral neuropathy in the limbs. Blood test results showed anemia, hypoproteinemia, and hypoalbuminemia. Immunoelectrophoresis detected kappa-type Bence-Jones protein in both the serum and urine. Bone marrow examination did not reveal an increase of plasma cells. Computed tomography showed intestinal distension and retention of intestinal contents...

BACKGROUND: Sera anti-enteric neuronal antibodies (AENA), neuronal inflammation, and degeneration in myenteric plexus in patients with irritable bowel syndrome (IBS) were reported. Effects of sera AENA in patients with IBS are unclear. METHODS: Patients with IBS met Rome III criteria were enrolled. Controls included healthy subjects (HS) and patients with slow transit functional constipation, inflammatory bowel disease, chronic intestinal pseudo-obstruction, and autoimmune diseases...

Gastrointestinal motility disorders are reflected in clinical medicine not only in the form of functional disorders but also as primary organic units or secondary manifestations of other diseases and physicochemical effects. Recent sophisticated diagnostic methods and basic research in the field of digestive tract motility have shown significant development. However, causal treatment of prokinetic motility disorders is still marginalized. A number of new effective drugs have been withdrawn from the market due to their significant side effects...

BACKGROUND: Chronic intestinal pseudo-obstruction (CIPO) and enteric dysmotility (ED) are severe intestinal motility disorders usually associated with underlying neuromuscular abnormalities. OBJECTIVE: To evaluate the in vitro neuromuscular function of patients with severe intestinal motility disorders. METHODS: Full-thickness intestinal biopsies (16 jejunum and 3 ileum) obtained from patients with CIPO (n = 10) and ED (n = 9) were studied using muscle bath and microelectrode techniques...

Chronic intestinal pseudo-obstruction (CIPO) is a major sign of mitochondrial disorders. We present the first reported case of fetal bowel dilation associated with Leigh syndrome. The possibility of CIPO should be taken into consideration even when mild fetal bowel dilation is detected.

We report a case of chronic intestinal pseudo-obstruction due to a generalized visceral autonomic neuropathy in an immune-competent patient infected with Strongyloides stercoralis . The patient had immigrated to the United States from Sierra Leone in childhood but had not returned for decades. His symptoms resolved with ivermectin treatment. Clinicians should have a high index of suspicion for strongyloidiasis in any patient with abdominal complaints and a history of travel to endemic areas, even if the travel history is remote...

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...
