LETTER TO THE EDITOR Retained capsule extraction 6 years after wireless bowel capsule endoscopy: The importance of follow up

Dear Sir

A 34 year old female with a 15 year history of ileal non-fistulizing Crohn's disease (CD) reported mild abdominal tenderness. Physical examination revealed a distended abdomen and a mildly tender right lower quadrant. She previously received steroids, 5-ASA, steroid suppositories, immunomodulators, and biological agents over the course of her disease. Her colonoscopy revealed a stenotic ileocecal valve. An abdominal X-ray suggested a retained capsule. The patient was unaware she had not passed the capsule after wireless capsule endoscopy (CE) 6 years prior. Computed tomography enterography (CTE) demonstrated a 9 cm segment of active ileitis with an ileo-ileal fistula and a retained capsule

in the same segment. The patient underwent laparoscopic ileocolic resection at which time the capsule was removed (Fig. 1). CE is superior in evaluating small-bowel (SB) CD and suspected CD compared to other modalities including: push enteroscopy, colonoscopy with ileoscopy, small bowel radiography (SB), CTE, and MRE. 1 Strictures should preclude WCE unless a patency capsule proves adequate passing. A patency capsule should be considered prior to CE in any patient with suspected stricture. However, CE may detect strictures or small bowel disease not seen on conventional imaging. 2 The C-reactive protein and Crohn's disease activity index (CDAI) score may not correlate with active CD found on CE. 3 Nineteen patients with small bowel obstructive symptoms 5/19 (26%) were found to have a lesion on CE that was not present on a previous imaging study. 4 Retention in CD patients undergoing CE ranges from 5 to 13%. 5,6 Endoscopic or surgical intervention may be employed as the primary method for retrieving a retained capsule, however steroids and biologic agents have proven as effective when active

e272 inflammatory non-stenotic CD is the etiology. 6 The risk of retention and surgery should be discussed prior to CE. This retained capsule was present in a CD patient for years prior to the development of symptoms. In patients new to a clinician or known to be non-compliant a patency capsule may prevent serious complications.
