Double-balloon endoscopy as the primary method for small-bowel video capsule endoscope retrieval.
ABSTRACT Capsule retention in the small bowel is a known complication of small-bowel video capsule endoscopy. Surgery is the most frequently used method of capsule retrieval.
To determine the incidence and causes of capsule retention and to describe double-balloon endoscopy (DBE) as the primary technique used for capsule retrieval.
Retrospective analysis of all video capsule studies was performed at our center, and evaluation of the outcome of DBE was the first method used to retrieve entrapped video capsules.
Tertiary referral center.
A total of 904 patients who underwent small-bowel video capsule endoscopy.
Capsule retrieval by DBE.
The number of patients in whom capsule retention occurred and the number of patients in whom an entrapped capsule could be retrieved by using DBE.
Capsule retention occurred in 8 patients (incidence 0.88%; 95% CI, 0.41%-1.80%) and caused acute small-bowel obstruction in 6 patients. All retained capsules were successfully removed during DBE. Five patients underwent elective surgery to treat the underlying cause of capsule retention. One patient required emergency surgery because of multiple small-bowel perforations.
In our series, the incidence of capsule retention was low. DBE is a reliable method for removing retained capsules and might prevent unnecessary surgery. If surgery is required, preoperative capsule retrieval allows preoperative diagnosis, adequate staging in case of malignancy, and optimal surgical planning.

ABSTRACT: The small bowel is anatomically difficult to examine; disease conditions are rarely located in it, but can be serious. Neither conventional radiography nor push enteroscopy has sufficient sensitivity and specificity to detect distinct lesions. Wireless capsule endoscopy can theoretically allow imaging of the entire small bowel, with only minimal discomfort for the patient. Between November 2001 and May 2003, 191 patients received 195 capsules. Data were collected retrospectively from consecutive patients in three centers. The indications for capsule endoscopy were obscure or occult bleeding, suspected Crohn's disease, or other reasons in 151, 25, and 15 patients, respectively. The clinical outcome after 6 months was evaluated on the basis of interviews with patients or relatives. Visualization of the entire small bowel was adequate in 78.4 % of the examinations. The colon was not reached in 16.9 % of cases, and there were minor technical problems in 4.6 %. Relevant pathological findings were identified in 56.2 % of 151 patients with obscure bleeding or iron-deficiency anemia (64 % of whom received blood transfusions). The most common findings were angiodysplasia in 39.7 % of cases and ulcers of the small bowel in 7.3 %. In addition, individual cases of tumors and parasitic worms were detected. Seven of the 25 patients with suspected Crohn's disease (28 %) had the disease confirmed. Three of five patients with polyposis syndrome of the colon were found to have polyps in the small bowel. Wireless capsule endoscopy can be recommended as part of the routine work-up in patients with obscure bleeding or iron-deficiency anemia. In patients with Crohn's disease, the method may be helpful in establishing or ruling out the diagnosis.Endoscopy 11/2004; 36(10):864-8. · 5.74 Impact Factor

ABSTRACT: Adenocarcinoma of the small bowel is a relatively rare malignancy as compared to the other malignancies of the gastrointestinal tract. Nonspecific presentation and infrequent occurrence often leads to a delay in diagnosis and consequent poor prognosis. Various other factors are of prognostic importance while managing these tumors. The medical records of a total of 27 patients treated for adenocarcinoma of the small bowel at Providence Hospital and Medical Centers from year 1990 through 2003 were reviewed retrospectively. Data were analyzed using SPSS software (version 10.0; SPSS, Inc., Chicago, IL). Survival analyses were calculated using the Kaplan Meier method with the log rank test to assess the statistical significance. The socio-demographics (age, gender) were calculated using frequency analyses. The patients included nine males and eighteen females with a median age at diagnosis of 62 years. Only 48% of the patients had an accurate preoperative diagnosis while another 33% had a diagnosis suspicious of small bowel malignancy. None of the patients presented in stage 1. The cumulative five-year survival was 30% while the median survival was 3.3 years. There was no 30-day mortality in the postoperative period in our series. The univariate analysis demonstrated that tumor grade, stage at presentation, lymph nodal metastasis and resection margins were significant predictors of survival.World Journal of Surgical Oncology 02/2008; 6:12. · 1.09 Impact Factor

ABSTRACT: The Given Capsule procedure is a new system designed to aid the gastroenterologist in diagnosing small-bowel disease. Capsule endoscopy has provided gastroenterologists with easy access to small-bowel mucosa for examination by direct visualisation. The aim of our prospective study was to determine the indication for capsule endoscopy and to describe the identified pathology within the gastrointestinal tract. Patients with unexplained gastrointestinal bleeding from suspected small-bowel pathology of an undisclosed nature or with unexplained abdominal pain for more than 6 months were eligible to undergo capsule endoscopy. Patients with suspected intestinal obstruction or with a history of major abdominal surgery were excluded. One hundred and sixty patients (70 women, 90 men; mean age 49.0 +/- 19.8 years, range 13-91 years) ingested the capsule easily. They had undergone 6 +/- 2.9 investigative procedures before capsule endoscopy. Two (1.25%) patients who had non-natural excretions underwent surgery: one was found to have Meckel's diverticulum and the other had stricturing Crohn's disease. The mean haemoglobin in iron-deficiency anaemia patients was 9.1 +/- 2.2 g%. The diagnostic yield of capsule endoscopy was 57.7% in iron-deficiency anaemia and 52.4% in suspected Crohn's disease. Capsule endoscopy detected the more clinically significant intestinal lesions. It was of diagnostic value in patients with obscure bleeding, suspected Crohn's disease and malabsorption, but the diagnostic yield in patients with chronic pain or irritable bowel syndrome-type symptoms was low.European Journal of Gastroenterology & Hepatology 10/2004; 16(9):927-31. · 1.92 Impact Factor
