Splenic pseudocyst as result of pancreatic ductal leak is not uncommon. Endoscopic drainage of splenic pseudocyst is generally not preferred because of risk of bleeding and difficult location to access endoscopically. Percutaneous drainage (PCD) and surgery are associated with high morbidity and can result into fistula formation. In this case report, we have demonstrated endoscopic ultrasound (EUS)-guided drainage of splenic pseudocyst communicating with pancreatic duct (PD).
A-35-year-old male who was suffering with recurrent acute pancreatitis for the last 4 years now presented with complaint of left upper quadrant pain and fever for 15 days. His laboratory evaluation showed leukocytosis and raised serum amylase and lipase. Magnetic resonance cholangiopancreatography (MRCP) showed increased size of pseudocyst compared with previous computed tomography (CT) scan and mildly dilated irregular PD communicating with splenic pseudocyst (100 × 112 mm) ([Fig. 1A–C]). On MRCP, pseudocyst was visualized within splenic capsule rather than in splenic bed ([Fig. 2A, B]). As there was high risk of fistula with PCD, EUS-guided drainage of splenic pseudocyst was performed. EUS-guided drainage of pseudocyst was performed with curvy-linear echoendoscope (UCT-180; Olympus ltd, Tokyo, Japan) in left lateral position under propofol sedation ([Video 1]). Collection was accessed from cardia and with 19-gauge (EZ shot 2, Olympus, Tokyo, Japan) needle. After puncturing collection dark brown color fluid was aspirated. Through the needle 0.025 guidewire (VisiGlide, Olympus corporation, Tokyo, Japan) was coiled into cavity and needle was then removed. Over the guidewire 6 Fr cystotome (Endo-flex GmbH Dusseldorf, Germany) was passed and tract was dilated and 7Fr 7CM double pig tail stent (Cook Medical, Bloomington, IN, USA) was deployed ([Fig. 3A–D]). Postprocedure CT showed significant reduction in size of collection. Plastic stent was preferred over the metal stent considering the puncture point in cardia and location of the pseudocyst, that is, splenic intracapsular to prevent subsequent complications (perforation and bleeding). Subsequently, he underwent endoscopic retrograde cholangiopancreatography. Initially PD cannulation was attempted via major papilla with a guidewire. Over the guidewire major papilla sphincterotomy (CleverCut 2, Olympus, Tokyo, Japan) was done; however, on further pushing guidewire was repeatedly getting curved and came out through minor papilla. Sphincterotome was then exchanged with needle knife and over the guidewire minor papilla papillotomy was performed. Initial guidewire was then withdrawn from major papilla and PD cannulation was done through minor papilla with tapered tip cannula. Guidewire was placed deep into the PD via minor papilla and pancreatogram was taken. Pancreatogram showed partial pancreas divisum with normal diameter PD and leak from tail region. Minor papilla sphincterotomy done and pancreatic stent (5Fr 12 cm single pigtail, Cook Medical, Bloomington, IN, USA) placed across the leak ([Fig. 4A–C]). Postprocedure patient was stable and discharged on oral antibiotics. On telephonic conversation with him, he was asymptomatic and both PD stent and cystogastric stent were removed at 3 months after resolution of collection at his primary care center.
