After the duodenal papilla was visualized (Figure 1(c)), a papillotome
was advanced through the 1st lumen to perform selective cannulation.
Endoscopic diverticulotomy with an isolated-tip needle-knife papillotome
(Iso-Tome) and a fitted overtube fort he treatment of a Killian-Jamieson diverticulum.
Precut technique can have needle knife precut (free hand cutting at the papillary orifice or cutting the papilla over a pancreatic stent), needle knife fistulotomy above papillary orifice, and transpancreatic precut sphincterotomy (TPS) using traction papillotome
ES was performed using JF260V (Olympus Medical Systems, Tokyo, Japan) as an endoscope and Autotome (Boston Scientific, Fremont, CA, USA) as a papillotome
. When the endoscope was advanced to the duodenum of the simulator, the papilla was observable.
The retained baskets were retrieved by a variety of strategies: extracorporeal shockwave lithotripsy (22), balloon dilatation (18), open surgery (9), a second Dormia basket (10), rescue mechanical lithotripter (5), exchange of metal wires (5), conservative management (2), exchange of metal sheaths (2), extension of sphincterotomy (2), laparoscopic surgery (2), laser lithotripsy (2), rat tooth forceps (2), goose neck snare (1), and papillotome
to the stone (1).
These included a TJF240/260 duodenoscope (Olympus, Japan), an APC300/ICC200EA high-frequency generator (Erbe, Tubingen, Germany), needle knife, papillotome
, guide wire, catheter, basket, balloon, nasobiliary drainage tube, plastic stent, UMG20-29R ultrasound probe(Olympus, Japan), cell brush, K-ras and P53 gene mutation detection kit and so on.
