Brief Summary

Access to the main bile duct is the first step in order to perform a therapeutic maneuver for biliary diseases. Early precut has been shown to ameliorate cannulation success rate, specially in difficult cannulation cases, when compared to guidewire cannulation (which is considered, for most, the standard technique). We aim to perform a randomized clinical trial comparing fistulotomy (F) precut vs guidewire cannulation (CC), as a primary cannulation technique, and compare outcomes between high experienced endoscopists (\> 200 ERCPs\[Endoscopic Retrograde cholangiopancreatography\]) and low experienced endoscopists (\< 200 ERCPs).

Study Arms (4)

Fistulotomy - High experienced

ACTIVE COMPARATOR

Fistulotomy precut with a needle knife, ERBE Endocut I, Effect 2; as the primary cannulation technique in high experienced endoscopists.

Procedure: Fistulotomy - High experienced.

Fistulotomy - Low experienced

ACTIVE COMPARATOR

Fistulotomy precut with a needle knife, ERBE Endocut I, Effect 2; as the primary cannulation technique in low experienced endoscopists.

Procedure: Fistulotomy - Low experienced.

Conventional (guidewire) cannulation- High experience

ACTIVE COMPARATOR

Conventional cannulation with an sphincterotome and 0.035 inch hydrophilic tip guidewire as the primary cannulation technique in high experienced endoscopists.

Procedure: Conventional (guidewire) cannulation- High experienced

Conventional (guidewire) cannulation - Low experienced.

ACTIVE COMPARATOR

Conventional cannulation with an sphincterotome and 0.035 inch hydrophilic tip guidewire as the primary cannulation technique in low experienced endoscopists.

Procedure: Conventional (guidewire) cannulation - Low experienced

Interventions

We will perform a duodenoscopy, once located next to the papilla, we will perform precut fistulotomy on the papillary infundibulum with a needle knife with EBRE, EndoCut I, Effect 2, until biliary fluid exit is seen or the biliary duct is noted, then we will access to the biliary tree to complete de procedure.

Fistulotomy - Low experienced

We will perform a duodenoscopy, once located next to the papilla, we will perform cannulation with sphincterotome and hydrophilic tipped guidewire aided by fluoroscopy, once the guidewire reaches de common bile duct (seen on fluoroscopy) we will continue with the procedure according to the patient's indication.
