Pre‐cutting using a noseless papillotome with independent lumens for contrast material and guidewire

Abstract

Although further studies with a large number of patients are needed to evaluate the efficacy of the papillotome, this papillotome may contribute to increase the safety and the success rate of precutting.

Evaluation of needle-knife precut papillotomy after unsuccessful biliary cannulation, especially with regard to postoperative anatomic factors

“…Precut papillotomy often is reported for limited diseases such as choledocholithiasis [11] or malignant biliary obstruction [26], and the number of patients with precut papillotomy and an actual diagnosis of cholelithiasis is thought to range from 12.5% to 65% [5,7,9,11,12,[14][15][16]. We found that with respect to the final diagnosis, biliary cannulation was not difficult in patients with choledocholithiasis, cholelithiasis, or both.…”

“…Failure to gain access into the bile duct is a common problem that can result from operator inexperience or anatomic reasons such as prior surgery [1,2]. When selective biliary cannulation is difficult, alternatives to the standard technique, such as precut papillotomy including fistulotomy or a combined percutaneous-endoscopic approach is required [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, these techniques often are associated with an increased potential risk for complications including bleeding, perforation, and pancreatitis.…”

Quantitative assessment of technical proficiency in performing needle-knife precut papillotomy

“…A variety of accessories and techniques for achieving the biliary cannulation has been described [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Although NKPP has been a useful alternative for achieving the selective biliary cannulation, the number of NKPP procedures required to achieve technical proficiency remains controversial.…”

“…Failure to gain access to the bile duct is a common problem that can occur due to operator inexperience or for anatomic reasons such as prior surgery [1][2][3]. When selective biliary cannulation is difficult by the standard technique, alternative procedures such as precut papillotomy, including fistulotomy or a combined percutaneous endoscopic approach, are required [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, these techniques often are associated with an increased potential risk for complications including bleeding, pancreatitis, and perforation.…”

New cannulation method for pancreatic duct cannulation-bile duct guidewire-indwelling method

“…To this end, various approaches are available for selective pancreatic duct difficult cannulation cases. These approaches, or methods, include the guidewire method [1] , two-devices-in-one-channel method [2] , flexible tip method [3] , pre-cut papillotomy [1,[4][5][6][7][8][9][10][11][12][13][14] , wire-guid-…”
