Endoscopic papillotomy and nasobiliary drainage during the course of common bile duct exploration: a report of 219 cases / 中华肝胆外科杂志

To explore the operation methods and indications of the duodenoscopic papillotomy (IEST) with endoscopic nasobiliary drainage (IENBD) for the treatment of duodenal papilla stenosis during the course of common bile duct operation.The clinical data of 219 cases of cholecystolithiasis with choledocholith and the stenosis of papillary underwent endoscopic sphincterotomy (IEST) plus endoscopic nasobiliary drainage (IENBD) in the Second People's Hospital of Chengdu were retrospectively analyzed.It was successful in 198 cases who had the gallbladder and common bile duct stones removed,and endoscopic papillary dissection was performed and the nasobiliary tube was successfully inserted.Nasobiliary drainage was successful in 186 cases (93.9％) of 198 cases.No liquid outflow was observed in nasobiliary drainage in 7 cases (3.5％).Nasal bile duct slipped early in 5 case (2.5％).Primary closure of bile duct incision was completed in 198 cases.It failed in 4 cases (2.0％) who had the bile leakage with primary closure of duct incision.Mild pancreatitis after operation occurred in 3 cases (1.5％).Nose bile duct ligation was performed in 1 case (0.5％).The overall postoperative complication rate was 4.0％ (8/198).IEST + IENBD in open laparotomy was successful in 21 cases.No perforation of intestine and bile duct,bleeding,severe pancreatitis and other complications and death were detected postoperatively in two groups.During the course of laparoscopy and open laparotomy,IEST + IENBD in treating cholecystolithiasis with choledocholith and the stenosis of papillary and primary closure of duct incision after the endoscopic nasobiliary drainage is safe and effective.

Difficult cannulation: what should I do before EUS guided access? / Canulación difícil: ¿qué hacer antes de acceso guiado por EUS?

Selective cannulation of the common bile duct can be difficult, so multiple strategies have been developed to overcome the situation. In this review we analize the different strategies that can be used like different papillotome instead of the standard catheter, precut papillotomy using precut needle knives or precut papillotome, transpancreatic papillary septotomy, and stenting of the pancreatic duct. Bile duct cannulation remains an important benchmark of successful ERCP. Alternative biliary access indication and its use is very important If biliary cannulation remains unsuccessful.The suprapapillary puncture is a promissory technique. It´s important to have in mind that the goal of all techniques is to provide acute pancreatitis decrease.

La canulación selectiva del conducto biliar común puede ser difícil por eso se han desarrollado diferentes estrategias para disminuir esta dificultad. La presente revisión analiza el uso de papilótomos diferentes en lugar del catéter estándar, la papilotomía con pre corte usando cuchillos o papilótomos, la septotomía papilar transpancreática y el uso de stents. La canulación biliar sigue siendo el factor más importante para considerar una ERCP como exitosa. Las indicaciones de accesos biliares alternativos y su uso es muy importante si esta falla. La punción suprapapilar es una técnica promisoria. Es importante tener en cuenta que la meta de todas las técnicas es disminuir la ocurrencia de pancreatitis aguda.
