Spontaneous disintegration of a retained video capsule in a patient with cryptogenic multifocal ulcerous stenosing enteritis: a rare complication

Cryptogenic multifocal ulcerative stenosing enteritis (CMUSE) diagnosed by retrograde motorized spiral enteroscopy

We present the case of a 59-years-old woman with a history of abdominal pain and iron-deficiency anemia. Upper and lower gastrointestinal endoscopy turned out negative and further investigation with wireless videocapsule showed an inflammatory stricture in the middle of the small bowel with retention of the videocapsule. Treatment with budesonide was initiated and allowed the spontaneous evacuation of the videocapsule. Retrograde motorized spiral enteroscopy was performed and confirmed an ulcerative stricture 60 cm proximal to the ileocaecal valve. Clinical, iconographic, endoscopic and histological results were compatible with a rare entity described as cryptogenic multifocal ulcerative stenosing enteritis (CMUSE). After the diagnosis budesonide was replaced by azathioprine 100 mg/d as an immunosuppressor. However, azathioprine induced mild pancreatitis and a second course of

Capsule retention caused by cryptogenic multifocal ulcerous stenosing enteritis

INTRODUCTION

cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare illness. Capsule retention (CR) has been reported in a few cases of CMUSE.

METHODS

we present four cases of CMUSE with CR. None of the patients showed any symptoms or signs of small bowel obstruction before capsule endoscopy (CE). All patients denied a history of non-steroidal anti-inflammatory drugs intake, radiotherapy treatment or abdominal surgery.

RESULTS

CE disclosed circumferential stenosis with or without ulcers in the small bowel, some accompanied by mucosal edema, white spots and nodules. All patients underwent an elective surgery to remove the retained capsule and resect the lesions.

CONCLUSION

CE plays a positive role in diagnosing CMUSE. CE findings are as important as CR to alert about the diagnosis of CMUSE.

Case report of cryptogenic multifocal ulcerous stenosing enteritis (CMUSE): a rare disease may contribute to endoscopy-capsule retention in the small intestine

Background

CMUSE is a rare disease whose diagnosis remains difficult because the lesion is confined to the small bowel.

Case presentation

Here, we present a case of 43-year-old female patient suffered chronic abdominal pain for 20 years, and finally diagnosed with CMUSE. Capsule endoscopy was performed when general endoscopic investigation failed to find the lesion, but the capsule was stranded in the small intestine. Moreover, capsule retention results in acute intestinal obstruction. Thus, surgery was performed and CMUSE was confirmed. The patient was recovered after partial small intestine resection.

Conclusions

Capsule retention occurred in nearly 60% of patients with CMUSE. Capsule endoscopy should be avoided when the patient is suspected of CMUSE, especially with severe anemia and radiologic finding in the ileum.

NASPGHAN Capsule Endoscopy Clinical Report

Wireless capsule endoscopy (CE) was introduced in 2000 as a less invasive method to visualize the distal small bowel in adults. Because this technology has advanced it has been adapted for use in pediatric gastroenterology. Several studies have described its clinical use, utility, and various training methods but pediatric literature regarding CE is limited. This clinical report developed by the Endoscopic and Procedures Committee of the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition outlines the current literature, and describes the recommended current role, use, training, and future areas of research for CE in pediatrics.

Contraindications for video capsule endoscopy

Video capsule endoscopy (VCE) has been applied in the last 15 years in an increasing field of applications. Although many contraindications have been put into perspective, some precautions still have to be considered. Known stenosis of the gastrointestinal tract is a clear contraindication for VCE unless surgery is already scheduled or at least has been considered as an optional treatment modality. In patients with a higher incidence of stenosis, as in an established diagnosis of Crohn’s disease, clinical signs of obstruction, prior radiation or surgical small bowel resection, a preceding test with the self-dissolving patency capsule can override this contraindication. Endoscopic placement of the capsule should be considered in patients with swallowing disorders to avoid aspiration. Esophageal or gastric motility disorders may require endoscopic capsule transport or application of prokinetics if the real-time viewer proofs delayed transit. In pregnant women, VCE should be restricted to urgent cases where diagnosis cannot be postponed after delivery, as data on safety are missing. There is theoretical and clinical evidence that patients with implanted cardiac devices such as a pacemaker, cardioverters or left heart assist devices, can safely undergo VCE in spite of still existing contraindication by manufacturers. Children from the age of 2 years have safely undergone VCE. Although video capsules are not proven safe with magnetic resonance imaging (MRI), first single cases of patients incidentally undergoing MRI with an incorporated capsule have been reported, showing susceptibility artifacts but no signs of clinical harm.

Severe Cryptogenic Multifocal Ulcerous Stenosing Enteritis. A Report of Three Cases and Review of the Literature

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, 60 years) were presented with colicky pain, repeated moderate ileous episodes and weight loss. Multiple fibrous strictures and ulcers of the small bowel were found. All three patients responded to glucocorticosteroid treatment. Tandem tight jejunal stenoses were dilated endoscopically by means of double balloon enteroscopy. In conclusion, CMUSE should always be considered when chronic moderate ileous episodes and multiple small intestinal strictures and ulcers of uncertain aetiology are found. Double balloon enteroscopy enables precise diagnostic work, possible endoscopic treatment of stenoses, may obviate the need for surgery and prevent excessive small bowel resections.

Cryptogenic multifocal ulcerous stenosing enteritis: a review of the literature

Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is an extremely rare illness characterised by chronic or relapsing subileus status resulting from multiple small intestinal fibrous strictures and multiple shallow ulcers of the small bowel. The etiology is unknown and pathogenesis is not fully understood. Therapy with systemic glucocorticosteroids is the treatment of choice. However, most patients develop corticosteroid dependence. Deep enteroscopy enables precise diagnostic work, possible endoscopic treatment of stenoses; may obviate the need for surgery and prevent excessive small bowel resections.

Cryptogenia multifocal ulcerous stenosing enteritis: an entity on its own as a cause of abdominal pain, iron deficiency anemia and protein-losing enteropathy

We studied a patient with edema secondary to protein losing enteropathy, and recurrent bouts of bloating and abdominal pain secondary to intestinal subocclusion episodes. After the clinical study, the patient was diagnosed of cryptogenic multifocal ulcerous stenosing enteritis (CMUSE), that is a rare disease, probably caused by mutations in the gene PLA2G4A, and characterized by multiple short stenosis of the small bowel with superficial ulcers, which do not exceed the submucosa layer. Inflammatory bowel disease (Chron's disease), intestinal tuberculosis and intestinal ulcers secondary to non-steroidal anti-inflammatory drugs are the main differential diagnosis. To sum up, physicians should included CMUSE in the differential diagnosis of recurrent abdominal pain, iron deficiency anaemia, occult intestinal bleeding, edema and protein losing enteropathy.

Cryptogenic multifocal ulcerous stenosing enteritis: A report of one case and review of the literature

Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare condition characterized by chronic or relapsing moderate ileus episodes resulting from multiple small intestinal strictures, multiple superficial ulcers of the small bowel and favorable therapeutic effect of glucocorticosteroids. Here we report a case of CMUSE in a 77-year-old female who presented with colicky pain, repeated moderate ileus episodes and weight loss. Multiple fibrous strictures and ulcers of the small bowel were found. The patient responded to glucocorticosteroid treatment. Severe tandem tight jejunal stenosis may be dilated endoscopically by means of double balloon enteroscopy. CMUSE should be considered when chronic moderate ileus episodes and multiple small intestinal strictures and ulcers of uncertain etiology are found. Double balloon enteroscopy enables precise diagnostic work, possible endoscopic treatment of stenosis, and may obviate the need for surgery and prevent excessive small bowel resections.

Endoscopic approach to capsule endoscope retention

In recent years, wireless capsule endoscopy has become increasingly indicated and utilized in the diagnosis and management of small bowel disorders. As such, its most common complication, capsule retention, has become a more frequently encountered clinical entity. Historically, when medical management of capsule retention has failed, patients have been sent directly to surgery. However, recent advances in small bowel enteroscopy have demonstrated a high success rate and safety profile in retrieving retained capsules. These approaches appear to be a viable alternative to surgery in many clinical scenarios. This article discusses both standard and advanced endoscopic approaches to capsule retention, and presents an algorithmic approach to their utilization.

Capsule retention: a feared complication of wireless capsule endoscopy

Wireless capsule endoscopy is a simple, non-invasive technique for the visualization of the entire small bowel. It was introduced in clinical praxis in 2001 and has already become the method of choice for the investigation of small-bowel pathology. Capsule retention is a major complication, with an overall incidence of 1-2%, although reported rates vary widely from 0% to 21%, depending on the indication for the examination. This complication can occur at any level of the gastrointestinal tract and in most cases runs asymptomatically. However, symptomatic bowel obstruction requiring surgical or endoscopic removal of the impacted capsule can occur. Rarely, capsule retention can lead to intestinal perforation. Despite several years of experience with wireless capsule endoscopy, there is up to the present no safe means of predicting capsule retention. Radiological studies have a low diagnostic yield and tend to underestimate or overestimate small-bowel strictures. The role of the new generation patency capsule (Agile patency capsule) needs to be further documented. The experts agree that obtaining a careful history is perhaps the best single method to detect the possibility of retention.
