A 52-year-old patient with chronic pancreatitis was admitted for drainage of two symptomatic pancreatic pseudocysts. Endoscopic ultrasonography (EUS) showed pseudocysts in the pancreatic body and head of 50 × 40 mm and 30 × 20 mm in size, respectively.
We first performed transgastric drainage of the pancreatic body pseudocyst, using a lumen-apposing stent. In the same session, we approached the pancreatic head pseudocyst. A transduodenal puncture of the cyst was made with a 19-gauge needle ([Fig. 1]). A cystotome was used, but it failed to get through the hard and thick cystic wall ([Fig. 2 a]). A through-the-scope balloon dilation was attempted, but without success. A 10-Fr Soehendra stent retriever (SSR) was then introduced through the scope over the guidewire ([Fig. 2 b]). As when it is used for difficult biliary stenoses [1] [2], we performed clockwise rotational movements while pushing the device into the cavity ([Fig. 3]). This maneuver finally allowed access to the pseudocyst, which was confirmed by outpouring of the contents of the cyst into the duodenum ([Fig. 4 a]). A double-pigtail stent (8.5 Fr, 4 cm) was inserted ([Fig. 4 b]; [Video 1]), allowing efficient drainage.
Quality:
The authors present this case to demonstrate the usefulness of the SSR, extending its utility, not only in difficult biliary stenosis but also as a device that may allow access into pancreatic pseudocysts with a hard and thick wall.
