A 64-year-old man was admitted to our hospital with abdominal bloating. Computed tomography
revealed a pancreatic pseudocyst located caudal to the body of the pancreas ([Fig. 1]). Endoscopic ultrasound (EUS)-guided pancreatic pseudocyst drainage was performed.
We used a 19-gauge fine-needle aspiration needle to target the gastric wall. A 0.035-inch
guidewire was advanced through the needle and the tract was dilated to 12 mm. A plastic
double-pigtail stent and a nasal cystic drainage tube (7 Fr) were then placed into
the passageway between the stomach and the cyst.

of the pancreas.
The patient developed massive hematemesis less than 24 hours after drainage of a pancreatic
pseudocyst. He underwent immediate endoscopy, which revealed a large blood clot in
the stomach lumen, with active bleeding still visible after rinsing with saline ([Fig. 2]). We considered the bleeding site to be at the puncture site but, unfortunately,
the continuous bleeding in the stomach cavity made it impossible to visualize the
bleeding site or the position of the stent. The acoustic shadow of the stent was however
detected by EUS in the stomach cavity ([Fig. 3 a]), and the stent was removed with foreign body forceps ([Fig. 3 b]). The nasal cystic drainage tube was replaced with a guidewire, and a partially
covered self-expandable metal stent (SEMS) was placed over the guidewire ([Fig. 4 a]). A double-pigtail stent was placed inside the partially covered SEMS to secure
the metal stent ([Fig. 4 b]). The stent placement was felt to be good and no active bleeding was observed during
30 minutes of endoscopic observation ([Fig. 5]; [Video 1]).

it impossible to identify the position of the stent.

Video 1 Endoscopic management of bleeding after endoscopic ultrasound-guided drainage of
a pancreatic pseudocyst.
The stent was removed 2 months after the patient’s discharge. During follow-up of
1 year, the patient had no further abdominal discomfort.
EUS-guided drainage is an effective treatment for pancreatic pseudocysts [1]
[2]. Bleeding is a relatively rare complication, but is tricky to manage. We hope that
this case can provide a new idea for the endoscopic treatment of patients with bleeding
after EUS-guided pancreatic pseudocyst drainage, allowing surgery to be avoided if
possible.
