Abstract

Tapered catheter protected by a telescopic sheath which is intended for the catheterisation of the minor caruncle. It consists of an extremely thin main catheter and an external sheath.

Description

Le cathétérisme de la caroncula minor pour l'opacification du Wirsung corporéocaudal par le Santorini est indispensable pour affirme; avec certitude l'existence d'un pancréas divisum, la plus fréquente des anomalles embryologiques pancréatiques, lorsoue le cathétérisme de la papille normale met en évidence un aspect radiologique compatible avec un pancréas ventral, pour le différencier d'un stop d'autre étiologie (cancer pancréatique, pancréatite chronique). The catheterization of the caroncula minor for the opacification of the Wirsung corporéocaudal by the Santorini is essential to affirm; with certainty the existence of a pancreas divisum, the most frequent of the pancreatic embryological anomalies, when catheterization of the normal papilla highlights a radiological aspect compatible with a ventral pancreas, to differentiate it from a stop of other etiology ( pancreatic cancer, chronic pancreatitis).

C'autre part afin d'apprécier le retentissement de l'existence du pancréas divisum sur ie Wirsung en cas de symptomatologie douloureuse (dilatation, temps de vidange) pour juger d'une éventuelle indication thé rapeutlcue.  On the other hand in order to appreciate the repercussion of the existence of the pancreas divisum on ie Wirsung in the event of painful symptomatology (dilation, time of emptying) to judge of a possible indication tea rapeutlcue.

2. Caractéristiques de ce cathéter
Dans ce nombreux cas la caroncula minor n'admet pas un cathéter normal c fait de l'étroitesse de son orifice. Divers artifices ont été proposés faisat appel à ces cathéters effilés ou à aiguille.2. Characteristics of this catheter
In this many cases the caroncula minor does not admit a normal catheter c because of the narrowness of its orifice. Various devices have been proposed using these tapered or needle catheters.

a) l'avantage de ce cathéter est sa finesse extrême permettant de cathéteriser ces orifices Ç la limite du détectable. a) the advantage of this catheter is its extreme fineness making it possible to catheterize these orifices Ç the limit of detectable.

- b) sa souplesse évite une injection sous muqueuse précoce gênant la poursuite de l'opacification en cas de mouvement de l'extrémité au bord de l'orifice. - b) its flexibility avoids an injection under precocious mucosa hampering the continuation of the opacification in the event of movement of the end at the edge of the orifice.

c) il coulisse dans une gaine qui protège l'extrémité fine du contact avec l'érecteur au moment de la sortie, et assure la tenue nécessaire à ce cathéter pour le guicer vers l'orifice de la minor. c) it slides in a sheath which protects the fine end from contact with the erector at the time of exit, and provides the necessary holding for this catheter to guide it towards the orifice of the minor.

d) il est souhaitable d'utiliser une seringue de 5 à 10 cc pour l'opa cification et d'autre part de cathéteriser avec l'endoscope en position non redressée au contraire de la papille normale. d) it is desirable to use a 5 to 10 cc syringe for opa cification and on the other hand to catheterize with the endoscope in an upright position unlike the normal papilla.

3. Autres utilisations possibles
Ce cathéter peut épalement être utilisé sot pour opacifier les voies pancréatiques par la caroncuic en En cas
la papille major (rare)
soit pour faciliter le cathétérisme profond de la voie biliaire princi
pale, le petit cathéter servant de guide pour la gaine dans certains
cas particuliers (orifice papillaire très étroit).3. Other possible uses
This catheter can also be used fool to opacify the pancreatic ways by the caroncuic in case of
the papilla major (rare)
either to facilitate deep catheterization of the main bile duct
pale, the small catheter that guides the sheath in some
special cases (very narrow papillary orifice).

4. Description technique
L'ensemble est réalisé en téflon. Le cathéter est de diamètre 1,2 mm. La gaine a un diamètre extérieur de 2,2 mm maximum. L'autre extrémité est pourvue d'un embout Luer lock en inox permettant l'injection du produit de contraste un mandrin métallique est introduit dans le cathéter afin de rigidifier la partie extérieure à l'endoscope. Un robinet peut être monté sur le raccord Luer lock. La pointe fine du cathéter est traitée et graduée pour repérer la longueur introdudite dans la papille (figure) 4. Technical description
The whole is made of Teflon. The catheter is 1.2 mm in diameter. The sheath has an outside diameter of 2.2 mm maximum. The other end is provided with a stainless steel Luer lock tip allowing the injection of the contrast product. A metal mandrel is introduced into the catheter in order to stiffen the part external to the endoscope. A tap can be mounted on the Luer lock fitting. The fine tip of the catheter is treated and graduated to identify the length introduced into the papilla (figure)
