Сapsule endoscopy for diagnosis of celiac disease.

In this review we analyzed the guidelines for diagnosis and management of celiac disease, as well as the recent studies published on this issue. Capsule endoscopy could be used in patients unwilling or unable to undergo conventional endoscopy, in patients who have discordant results between serological and histopathological investigation, in patients with nonresponsive or refractory celiac disease.

[Clinical application of a modified trocar for the treatment of maxillary sinus pathology].

A new instrument has been developed to facilitate access into a maxillary sinus for the purpose of diagnostic endoscopy and adequate surgical sanation. The cannula of this trocar has a proximal coniform portion and a distal cylindrical part with a lateral aperture and a fixing tip. Such design ensures perfect sanation of the maxillary sinus.

[Experimental morphological substantiation of the surgical treatment of paranasal sinuses].

This experimental morphological study conducted on the rabbit model has demonstrated that the use of a modified trocar with "buried facets" for maxillary microsinusotomy allowed surgical trauma to be substantially reduced compared with the traditional approach. With the new instrument, the volume of hemorrhage was lower and the inflammatory reaction weaker while large necrotic zones with leukocytic infiltration were virtually absent. As a result, reparative processes developed faster and healing took less time.
