BACKGROUND AND AIM: Endoscopic ultrasound guided pancreatic pseudocyst drainage (EUS-PPD) is increasingly being used for management of pancreatic pseudocysts. We evaluated the outcome and complications of EUS-PPD with modified combined technique by inserting both endoprosthesis and naso-cystic drain.

METHODS: Forty patients referred between August 2007 and January 2010 for EUS-PPD were prospectively studied. EUS-PPD was attempted for symptomatic pancreatic pseudocysts which were; (i) resistant to conservative treatment, (ii) in contact with the gastric or duodenal wall on EUS and (iii) having no bulge seen on endoscopy. Controlled radial expansion wire guided balloon dilation of the puncture tract was performed followed by insertion of a 10 French double pigtail stent and 7-Fr naso-biliary drain. The early and late outcome and complications of EUS-PPD were analyzed.

RESULTS: Thirty-two patients had non-infected and eight had infected pseudocysts. EUS-PPD was technically successful in all. Pseudocysts resolved completely in 39 patients, while one with infected pseudocyst underwent surgical resection for bleeding in the cyst. Naso-cystic drain was removed in 39 patients after median duration of 13 days. Thereafter, the double pigtail stent was removed in all cases after median duration of 10 weeks. Pseudocyst recurred in one patient requiring a second session of EUS-PPD. All 32 patients without cystic infection were successfully treated by EUS-PPD. Seven out of eight patients (87%) with cystic infection were successfully treated by EUS-PPD.

CONCLUSION: Endoscopic ultrasound guided pancreatic pseudocyst drainage with modified combined technique is safe and is associated with high success rate.
