Capsule endoscopy in diagnosis of small bowel Crohn′s disease

AIM: To evaluate the effectiveness of wireless capsule endoscopy in patients with suspected Crohn′s disease (CD)of the small bowel undetected by conventional modalities,and to determine the diagnostic yield of M2A Given Capsule.METHODS: From lay 2002 to April 2003, we prospectively examined 20 patients with suspected CD by capsule endoscopy. The patients had the following features:abdominal pain, weight loss, positive fecal occult blood test, iron deficiency anaemia, diarrhoea and fever. All the patients had normal results in small bowel series (SBS)and in upper and lower gastrointestinal endoscopy before they were examined. Mean duration of symptoms before diagnosis was 6.5 years.RESULTS: Of the 20 patients, 13 (65%) were diagnosed as CD of the small bowel according to the findings of M2A Given Capsule. The findings detected by the capsule were mucosal erosions (2 patients), aphthas (5 patients),nodularity (1 patient), large ulcers (2 patients), and ulcerated stenosis (3 patients). The distribution of the lesions was mainly in the distal part of the small bowel,and the mild degree of lesions was 54%.CONCLUSION: Wireless capsule endoscopy is effective in diagnosing patients with suspected CD undetected by conventional diagnostic methods. It can be used to detect early lesions in the small bowel of patients with CD.

Diagnosing small bowel Crohn's disease with wireless capsule endoscopy

BACKGROUND: The small bowel is the most commonly affected site of Crohn's disease (CD) although it may involve any part of the gastrointestinal tract. The current methodologies for examining the small bowel are x ray and endoscopy. AIMS: To evaluate, for the first time, the effectiveness of wireless capsule endoscopy in patients with suspected CD of the small bowel undetected by conventional modalities, and to determine the diagnostic yield of the M2A Given Capsule. PATIENTS: Seventeen patients (eight males, mean age 40 (15) years) with suspected CD fulfilled study entry criteria: nine had iron deficiency anaemia (mean haemoglobin 10.5 (SD 1.8) g%), eight had abdominal pain, seven had diarrhoea, and three had weight loss. Small bowel x ray and upper and lower gastrointestinal endoscopic findings were normal. Mean duration of symptoms before diagnosis was 6.3 (SD 2.2) years. METHODS: Each subject swallowed an M2A Given Capsule containing a miniature video camera, batteries, a transmitter, and an antenna. Recording time was approximately eight hours. The capsule was excreted naturally in the patient's bowel movement, and the data it contained were retrieved and interpreted the next day. RESULTS: Of the 17 study participants, 12 (70.6%, six males, mean age 34.5 (12) years) were diagnosed as having CD of the small bowel according to the findings of the M2A Given Capsule. CONCLUSIONS: Wireless capsule endoscopy diagnosed CD of the small bowel (diagnostic yield of 71%). It was demonstrated as being an effective modality for diagnosing patients with suspected CD undetected by conventional diagnostic methodologies.

Non-small-bowel abnormalities identified during small bowel capsule endoscopy

AIM:To investigate the incidence of non-small-bowelabnormalities in patients referred for small bowel capsule endoscopy,this single center study was performed.METHODS:Small bowel capsule endoscopy is an accepted technique to investigate obscure gastrointestinal bleeding.This is defined as bleeding from the digestive tract that persists or recurs without an obviousetiology after a normal gastroduodenoscopy and colonoscopy.Nevertheless,capsule endoscopy sometimesreveals findings outside the small bowel,i.e.,withinreach of conventional endoscopes.In this retrospectivesingle center study,595 patients undergoing capsuleendoscopy between 2003 and 2009 were studied.Theincidence of non-small bowel abnormalities was defined as visible abnormalities detected by capsule endoscopy that are located within reach of conventionalendoscopes.RESULTS:In 595 patients,referred for obscure gastrointestinal bleeding or for suspected Crohn’s disease,abnormalities were found in 306(51.4%).Of these 306patients,85(27.7%)had abnormalities within reach of conventional endoscopes;63 had abnormalities apparently overlooked at previous conventional endoscopies,10 patients had not undergone upper and lower endoscopy prior to capsule endoscopy and 12 had abnormalities that were already known prior to capsule endoscopy.The most common type of missed lesions were vascular lesions(n=47).Non-small-bowel abnormalities were located in the stomach(n=15),proximal small bowel(n=22),terminal ileum(n=21),colon(n=19)or at other or multiple locations(n=8).Ten patients with abnormal findings in the terminal ileum had not undergone examination of the ileum during colonoscopy.CONCLUSION:A significant proportion of patients undergoing small bowel capsule endoscopy had lesions within reach of conventional endoscopes,indicating that capsule endoscopy was unnecessarily performed.     

Clinical utility of wireless capsule endoscopy: experience with 200 cases

GOALS: To evaluate the indications and diagnoses made with 200 small bowel capsule endoscopies in an academic medical center. BACKGROUND: Wireless capsule endoscopy (PillCam SB) has recently become available as a new tool in the evaluation of patients with small bowel diseases. Its impact on patient care and usefulness in clinical practice has steadily been gaining ground, yet there are few studies that evaluate large numbers of patients. METHODS: A retrospective review of wireless capsule endoscopies was performed between September 2003 and January 2005. Reviewed are the indications for the studies, number of complete and incomplete examinations, evaluation of gastric and small bowel transit times, findings made on examination, and the percent of diagnoses made and diagnoses suspected for each study indication. RESULTS: A total of 200 cases were reviewed. Indications included anemia (66% of cases), gastrointestinal hemorrhage (31% cases), abdominal pain (21% cases), diarrhea (11% cases), and other indications such as evaluation of abnormal radiographic findings or surveillance of inflammatory bowel disease (9% cases). The average patient age was 61.5 years (SD +/- 19.1 years). Males comprised 49% of patients. The wireless capsule endoscopy study completely evaluated the entire small bowel in 87% of cases. The most common cause for an incomplete examination was premature battery failure in 8% of cases. Only 9.5% of studies were normal without findings. Small bowel ulcerations were present in 38% of studies. Vascular ectasias were present in 23% of studies. Overall, a diagnosis was made in 23% of all studies, whereas a diagnosis was suspected based on the findings in an additional 31% of studies. The indication with the highest percentage of diagnoses made or suspected was gastrointestinal hemorrhage, with a diagnostic yield of 65%, followed by anemia 61%, diarrhea 36%, and pain 17%. CONCLUSIONS: Wireless capsule endoscopy is a valuable diagnostic tool in the evaluation of occult small bowel lesions, and was most effective in patients with gastrointestinal hemorrhage and anemia.     

The role of capsule endoscopy in small bowel Crohn's disease

Video capsule endoscopy is an invaluable tool for examining the small bowel. It is non-invasive and generally well tolerated, however its role in the assessment of the severity and extent of small bowel Crohn's disease has not, to date, been adequately evaluated.MethodsAll capsule endoscopies performed over a two year period in a tertiary referral centre in subjects with known or suspected Crohn's disease were reviewed.ResultsTwenty-six capsule endoscopy studies in total were included. These were performed in 15 cases of known Crohn's disease, 5 cases of suspected Crohn's disease, 3 cases of endoscopically diagnosed non-specific terminal ileal inflammation and finally 3 post colectomy cases of indeterminant being considered for IPAA formation. Ten patients known to have small bowel Crohn's disease were prospectively recruited; of 3 with normal small bowel follow through or CT exams, one had an abnormal capsule endoscopy. The other 7 patients had small bowel follow through or abdominal CT scans consistent with small bowel Crohn's disease; additional mucosal abnormalities were detected by capsule endoscopy in 6 cases with capsule retention in the stomach in one. Of 5 with colonic Crohn's disease normal small bowel imaging corresponded with normal capsule endoscopy in all but one. A diagnosis of Crohn's disease was made in 2 out of 5 cases of suspected Crohn's disease on the basis of the capsule endoscopy findings. Three patients with non-specific acute terminal ileal inflammation at ileocolonoscopy were confirmed to have ongoing inflammation. The capsule was retained in four subjects beyond 24 h.ConclusionCapsule endoscopy more accurately determines the severity and extent of the Crohn's disease in the small bowel than traditional imaging modalities.
