Capsule endoscopy is safe and effective after small-bowel resection.
ABSTRACT Because capsule endoscopy is a relatively new technique, the indications, the contraindications, and the complications of the procedure have not been fully delineated. The present study was undertaken to determine the utility and the safety of capsule endoscopy in patients who have undergone small-bowel resection.
Ten patients (mean age 48.5 [8.4] years) were included in the study. Eight had undergone surgical resection for Crohn's disease and two for malignancy. Indications for capsule endoscopy included suspected relapse of Crohn's disease or of malignancy, with a negative conventional evaluation that included barium contrast radiography, upper endoscopy, colonoscopy, US, CT, and push enteroscopy. Capsule endoscopy was performed in the standard fashion.
No side effects were observed in any patient. Natural excretion of the capsule was reported at a mean of 72 hours. In 7 patients (70%), capsule endoscopy revealed recurrence of disease in the small bowel: one recurrent malignancy, 6 recurrent Crohn's disease. The information gained was helpful with respect to further treatment for all of these patients.
Capsule endoscopy is safe and effective in the evaluation of patients who have undergone surgical resection of the small bowel for benign or malignant disease.

ABSTRACT: Wireless endoscopy consists of a small-sized device which allows gastrointestinal tract images to be taken as it physiologically advances along its lumen after being orally ingested. Its primary contribution is the study of small bowel conditions, a gastrointestinal tract segment in which diagnosis difficulties still arise when using current tests, including enteroscopy. Preliminary studies in animals and healthy subjects have revealed data on image quality, sensitivity, specificity, and safety that demonstrate the benefits of this new technique. This review discusses technical aspects, indications and contraindications, as well as studies reported so far on this endoscopic diagnostic procedure.Revista espanola de enfermedades digestivas: organo oficial de la Sociedad Espanola de Patologia Digestiva 10/2001; 93(9):598-605. · 1.65 Impact Factor

ABSTRACT: 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.Gut 01/2003; 52(3):390-392. · 10.73 Impact Factor
