Videocapsule endoscopy (VCE) has become a routineinvestigative toolin the diagnosis ofsmall bowel diseases.Retention of theVCEis a seriouscomplicationof this examination. The retention leads to the occurrence of acute intestinalobstruction or intestinal perforationrequiring emergency surgery [1,2]. We report the case of VCE retention on small bowel stenosis due to CROHN disease.

 

 

A 30-year-old woman without medical history had undergoing an exploration by VCE three months ago for digestive symptoms as diffuse abdominal pain, chronic constipation, Iron-deficiency anemia and alteration of general state. The patienthas not eliminatedthecapsuleafter48 hours.Plain abdominal radiography showed persistence of VCE (Figure 1). Thereafter, the patient began toexhibitrepeated subocclusifsyndrome. She underwent surgical exploration that showed wall thickening and incomplete strictures at multiple levels of small bowel compatible with ileal Crohn´s disease. The VCE was enclosed in stricture located 2 meters from duodenojejunal junction. A longitudinalenterotomy on the stricture with VCE extraction was performed (Figure 2, Figure 3). The enterotomy was repaired by stricturoplasty. The postoperative course was uneventful.

 

 

Capsule retention is defined by the International Conference on Capsule Endoscopy (ICCE) 2005 as having a capsule endoscope remain in the digestive tract for minimum two weeks. Capsule retention is further defined as the capsule remaining in the bowel lumen unless it is recovered medically, endoscopically or surgically [3].

 

Retention rate of VCE depends mainly on its indications. It goes from 0% in subjects without any gastrointestinal disease to 21% in cases of intestinal obstruction [4]. This rate is 5% in patients suspected Crohn’s disease. Liao et al [5], reported 184 cases of retention (1,4%) among 22840 explorations with VCE of which 2,6% occurred on Crohn’s disease, 1,2% on obscure gastrointestinal bleeding and 2,1% on gastrointestinal neoplasm. Furthermore, AINS induced enteropathy, post-operativestenosis, ischemia and radiation enteritis can occur retention [5,6]. Meckel’s diverticulum, peptic ulcer, cryptogenic multifocal stenosing enteritis can rarelybeinvolved with frequencies of less than 2% of total capsule retention. In our patient,theretentionoccurred probably on crohn’s disease [4].

 

Retention of capsule is mostly asymptomatic. Furthermore, it causes subocclusif symptoms [2,5]. Retention can contribute to etiological diagnosis and the level of obstruction [2]. Some acute complications due to retention of VCE were reported in literature. In a study of 2300 explorations by VCE, six cases have acute intestinal obstruction [1]. One case of intestinal perforation 2 months after par VCE examination for exploration of anemia was reported [7].

 

The management of capsule retention can undergo expectant, medical and endoscopic procedure or even surgical intervention. Medicaltreatment is based on anti-inflammatories, colonic preparation or rectal enema [1,8]. Surgery allows not only the extraction of the capsule but can also contribute to treatment of the etiology of retention and prevents its complications [5,7]. The longest duration of retention is reported by Bhattarai et al [9], the capsule was retained on ileorectal anastomosis without complication during 4,5 years and it was successfully removed by endoscopic procedure. Hauser et al [10] reported two cases of VCE retention. In the first case, VCE was located in proximal jejunum and successfully removed by enteroscopy, in the second case; VCE was located in rectum and removed by surgery after failure colonoscopy. Liao et al [5] reported spontaneous elimination or by medical treatment in 15%, by endoscopic procedure in 12% andby surgery in 58,7% of the cases with retention capsule. One death attributed to surgery complication was reported [1]. Our patient underwent surgery extraction with treatment of stenosis by stricturoplasty. The postoperative course was uneventful.

 

 

VCE retention is a serious complication this examination. Although rare, we must keep inmind the possibilityof an acute complication of retention of the VCE. Surgical treatment must be considered in case offailure ofendoscopicextractionandifa cause of retention requires surgery.Surgical treatmentallows the extraction ofthecapsule, the treatment of the cause and preventsacutecomplications of retention.
