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.
Retrospective design.
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: La VCE, utilisée depuis plus de 10 ans, est devenue l’examen de référence pour l’exploration de l’intestin grêle. Trois autres vidéocapsules de l’intestin grêle ont également été développées plus récemment. Cette fiche technique résume les caractéristiques des différentes capsules disponibles, la procédure de l’examen et ses indications.

    ABSTRACT: This paper has described the theoretical design of a wideband circular L-probe patch antenna covering the ISM band of 2.4GHz. To increase the effective radiation area, the antenna is spherically conformed. To overcome the dielectric material cracking in the commercial microstrip due to the spherical distortions, an air dielectric is assumed, making the design of the antenna very simple and inexpensive. A grid pattern is overlayed on a planar 1.6mm thick commercial grade piece of aluminium cut to a circle with a radius of 100mm. This material is spherically conformed and the distortions measured to become the basis of the spherical conformal ground plane and the benchmark of the conformal element design. The different S<sub>11</sub> responses of the antenna are shown for different values of the element radius. The radiation pattern for the conformal antenna design shows an increase in the effective radiation area when compared to the flat antenna design. The conformal design also has a response similar to a λ/4 monopole with a maximum gain of 6dB.

    ABSTRACT: In recent years, wireless capsule endoscopy has become increasingly indicated and utilized in the diagnosis and management of small bowel disorders. As such, its most common complication, capsule retention, has become a more frequently encountered clinical entity. Historically, when medical management of capsule retention has failed, patients have been sent directly to surgery. However, recent advances in small bowel enteroscopy have demonstrated a high success rate and safety profile in retrieving retained capsules. These approaches appear to be a viable alternative to surgery in many clinical scenarios. This article discusses both standard and advanced endoscopic approaches to capsule retention, and presents an algorithmic approach to their utilization.
