Dear Editor,

Pancreatic fluid collections (PFCs) are an important local consequence of both acute and chronic pancreatitis. The PFC can present with a number of complications including pain, infection, gastric outlet obstruction, biliary infection, and hemorrhage into the cyst. Intracystic bleeding is a rare but potentially lethal complication of pancreatitis that commonly occurs due to a leaking pseudoaneurysm (PA).[1] Bleeding pseudocysts with arterial PA are treated surgically or a combined radiological and endoscopic approach of initial angioembolization followed by either endoscopic transpapillary or transmural drainage.[2],[3] However, all patients with intracystic bleed do not have an arterial PA, and other causes such as venous bleeding and diffuse small-vessel hemorrhage from the walls of PFC can also lead to bleed into the PFC.[4] The management of hemorrhagic PFCs without a detectable PA either on computed tomography angiography (CTA) or EUS is a therapeutic dilemma. Because of better ability to identify the cause as well as control the bleed, most of these patients are treated surgically. The experience with endoscopic transmural drainage of such hemorrhagic PFCs is limited, and therefore, we retrospectively evaluated the safety and efficacy of endoscopic transmural drainage in patients with hemorrhagic PFC without a detectable PA.

The records of 13 patients (mean age: 35.9 ± 6.9 years; 11 males) with hemorrhagic PFC without a detectable PA either on CTA or EUS seen over the last 10 years and treated with EUS-guided transmural drainage were retrieved and analyzed. All the studied patients had bled into the PFC as demonstrated on CT abdomen as a collection with a high-attenuated fluid and/or fluid–fluid levels or hyperdense contents and confirmed by aspiration of hemorrhagic fluid during EUS-guided drainage [Figure 1]. After obtaining informed consent, patients underwent EUS-guided transmural drainage of the hemorrhagic PFC [Figure 1]. Postprocedure patients were admitted and carefully watched for bleeding. The treatment success was defined as symptomatic improvement with resolution of PFC on cross-sectional imaging with no need for rescue surgery.{Figure 1}

The etiology of pancreatitis was alcohol, gallstones, and idiopathic in 8, 2, and 3 patients, respectively. Five (38%) patients presented with abdominal pain and gastrointestinal bleed whereas 8 (62%) patients presented with increasing abdominal pain only. The mean size of PFC was 11.1 ± 2.7 cm, and CT revealed high-attenuation fluid in all the patients. Eleven (85%) patients had coexistent splenic vein thrombosis and perigastric venous collaterals, but none had esophagogastric varices. EUS demonstrated prominent vessels in the wall of the PFC in 3 (23%) patients. Endoscopic drainage was technically successful in all 13 patients, and 9 patients underwent transmural drainage with multiple plastic stents whereas 4 patients were treated with lumen-apposing metal stents. Direct endoscopic necrosectomy was needed in 3 (23%) patients. The PFC resolved in all patients within 20.6 ± 5.9 days. None of the treated patients developed postprocedural bleeding nor any patient required postprocedure blood transfusion. Following resolution of PFC, patients underwent magnetic resonance cholangiopancreatography and plastic transmural stents were left for indefinite period in patients with disconnected pancreatic duct (n = 5). In the remaining 8 patients, transmural stents could be removed uneventfully. There has been no recurrence of PFC in successfully treated patients.

In conclusion, endoscopic transmural drainage seems to be safe and effective in patients with hemorrhagic PFC without a detectable PA.
