The pancre- atic cancer was located in the pancreatic head, whereas the pancreatic stone was located in the pancreatic body (Fig. 1). After pancreatitis was resolved, transpapillary pancreatic duct drainage was attempted, but the guide wire could not be deployed over the pancreatic duct stric- ture caused by the tumor. Then, EUS-PD was performed to prevent pancreatitis induced by a pancreatic duct stric- ture. The patient was placed under sedation with a bolus infusion of 0.05 ml/kg propofol. The dilated pancreatic duct from the tail side of the stone, as viewed echoendo- scopically (GF-UCT260; Olympus) from the stomach po- sition, was punctured with a 19-gauge needle (Sonotip; Medi-Globe), with correct puncturing confirmed with contrast medium (Fig. 2). A 0.025-inch guidewire (Visi- Glide2; Olympus) was inserted toward the pancreatic tail. After dilating the fistulous tract using a diathermic dila- tor, a 7-Fr plastic stent (7 cm in length; Boston Scientific) was successfully deployed (Fig. 3). There were no compli- cations during the procedure. Seven days later, the pa- tient’s serum amylase concentration had decreased to 88 U/L and he started dietary intake. One month after the procedure, he resumed chemotherapy, with no recur- rence of pancreatitis to date.

In this case, EUS-PD was useful as salvage therapy for pancreatitis as the trans- papillary approach was difficult. © 2017 S. Karger AG, Basel Endoscopic ultrasound-guided pancreatic drainage (EUS-PD) has been described as a new drainage technique after unsuccessful transpapillary approach for pancreatic duct strictures [1–3]. Our patient was a 74-year-old man with unresectable pancreatic cancer re- ceiving chemotherapy. Due to repeated pancreatitis, however, he could not continue treatment and was forced to stop chemotherapy. The patient had no history of chronic pancreatitis but abdominal CT showed a pancre- atic duct stone in the main pancreatic duct at the pancre- atic body. The main pancreatic duct was slightly dilated Published online: December 20, 2017 Dr. Mamoru Takenaka Department of Gastroenterology and Hepatology Kindai University Faculty of Medicine 377-2 Ohno-Higashi, Osaka-Sayama, Osaka 589-8511 (Japan) E-Mail mamoxyo45  @  gmail.com © 2017 S.
