Background and Study Aims: Portal hypertension often coexists with pancreatic pseudocysts and is potentially dangerous if a collateral vessel is in the vicinity of the needle puncture pathway. Hitherto, there have been no reports of pseudocyst drainage in this setting.
Patients and Methods: Patients who underwent endoscopic ultrasound (EUS)-guided pancreatic pseudocyst drainage complicated by intervening vessels were assessed for success and outcomes. An Olympus mechanical linear-array video echo endoscope GF-UM 140D was used for the drainage procedure in all patients. Either a ”hot” diathermy technique was employed or a ”cold” technique using direct aspiration with a 19-G needle, followed by deployment of a nasocystic catheter.
Results: Eight patients with a symptomatic pseudocyst and intervening vessels underwent drainage that was guided (n = 6) or assisted (n = 2) by EUS. All were found to have successful resolution of the cyst at follow-up 6 weeks later, while segmental portal hypertension had disappeared in one patient. There were no major complications. One patient had transient hemorrhagic drainage that resolved by itself.
Conclusions: Pseudocysts complicated by portal hypertension or by intervening vessels can be safely drained under EUS guidance, even in the absence of color Doppler imaging.
