IntroductionCryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare condition characterised by chronic or relapsing moderate ileous episodes resulting from multiple small intestinal strictures, multiple shallow ulcers of the small bowel and beneficial therapeutical effect of glucocorticosteroids (1, 2). Japanese gastroenterologists call this syndrome chronic non-specific multiple ulcers of the small intestine (CNSU) (3). The aetiology of CMUSE has not been clarified yet and pathogenesis is still poorly understood. Some authors even doubt the real existence of this entity.Patients with CMUSE are often referred for surgery because of symptomatic small intestinal strictures and several resections of the small bowel had to be performed.We report three cases of CMUSE diagnosed within the past 10 years at a single tertiary centre, where more than eight thousand GI endoscopies are performed per year. Review of available relevant literature is provided. Case reports Case 1A 35-year-old woman was admitted to our department because of chronic diarrhoea, colicky abdominal pain, weight loss (16 kg during previous five years) and repeated moderate ileous episodes. She was cachectic (body-mass index 12.8 kg/m 2 ). Laboratory tests showed iron-deficiency anaemia (haemoglobin 96 g/L), thrombocytosis (459.10 9 g/L) and proteino-energy malnutrition (serum prealbumin 0.17 g/L). Abdominal ultrasound revealed strenuous small intestinal peristalsis and a large volume of fluid in the intestinal loops. Enteroclysis provided no further information. Gastroscopy and colonoscopy were normal. Push-enteroscopy found multiple shallow ulcers of the distal duodenum and proximal jejunum ( Fig. 1) and increased stagnant fluid content in the proximal part of the small bowel. A non-specific inflammatory process was detected at histology and electron microscopy of small intestinal biopsy specimens. Coeliac disease, lymphoma, Crohn's disease and vasculitis were excluded. No infective agent was found. Total parenteral nutrition and glucocorticosteroids improved her general condition including nutritional status (serum albumin 35.8 g/L, prealbumin 0.29 g/L, body-mass index 13.4 kg/m 2 ). The patient was discharged on enteral nutrition, glucocorticosteroids (prednisone was gradually replaced by budesonide) and 5-aminosalicylates. She was followed-up at regular controls. Nine months later the patient had to be admitted because of a worsened general condition (frequent watery stools, fatigue, oedemas of lower extremities, fluidothorax and ascites). Laboratory tests revealed hypo-25 CASE REPORT Summary: Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare condition characterised by chronic or relapsing moderate ileous episodes resulting from multiple small intestinal strictures, multiple shallow ulcers of the small bowel and favourable therapeutical effect of glucocorticosteroids. The aim of this paper was to evaluate three cases of CMUSE diagnosed within 10 years at a tertiary gastroenterology centre. Three females (35, 50, ...
The aim of this project was to develop a methodology to introduce wireless video capsule endoscopy in preclinical research. Five mature female pigs (Sus scrofa domestica) were selected for the study. Capsule endoscopes (the EndoCapsule system; Olympus) were introduced into the duodenum endoscopically in each of the animals. The life span of batteries (i.e., total time of endoscopy recording) was 487–540 min (median 492 min). The capsule endoscope reached the cecum during enteroscopy once (after 7 h 57 min), in the remaining cases, endoscopy recordings terminated in the distal or terminal ileum. All capsule enteroscopies found a normal pattern of the small intestine. The intestinal lumen is narrower, transverse folds are sparse or even absent, villi are wider but less prominent in pigs compared to humans. Capsule endoscopy in experimental pigs will be helpful for future trials on injury of different drugs and xenobiotics to the small bowel.
IntroductionMeckel’s diverticulum is the most common congenital anomaly of the gastrointestinal tract. Authors present a 67-year-old woman treated for iron deficiency anemia for the past 5 years. Suddenly, her disease was presented with painless severe gastrointestinal bleeding (fresh melena). Inverted Meckel’s diverticulum with ectopic pancreatic tissue as a source of severe gastrointestinal bleeding was diagnosed by intraoperative enteroscopy.ConclusionA combination of inversion of Meckel’s diverticulum with ectopic pancreatic tissue is extremely rare, particularly in elderly patient. Capsule endoscopy, double balloon enteroscopy, and ultimately intraoperative enteroscopy may be helpful in timely diagnosis.
