GOMEZ ZULETA, Martín A; LUQUEZ MINDIOLA, Adán  and  RUIZ MORALES, Óscar Fernando. Case Series of Drainage of Pancreatic Pseudocysts Guided by Echoendoscopy without Fluoroscopy. Rev Col Gastroenterol [online]. 2017, vol.32, n.2, pp.160-165. ISSN 0120-9957.


Pancreatic pseudocysts can be drained by surgical, laparoscopic, percutaneous, and endoscopic methods. Endoscopic methods have become the most widely accepted nowadays since they are simpler and generate less morbidity and mortality. They have always been associated with the use of fluoroscopy, which adds complexity. This study presents our drainage technique which is guided by echoendoscopy rather than fluoroscopy.

Materials and methods:

The objective of this study is to describe a technique for drainage of pancreatic pseudocysts which does not use fluoroscopy to guide the endoscope. Instead, echoendoscopy guides the instrument. We report a case series of 10 patients who underwent transgastric drainage and describe the technique, complications and results during follow-up.


Ten consecutive patients, five women and five men, were included in this study. Ninety percent were cases in which the body of the pancreas had been compromised. Cystogastrostomy was successfully performed in nine patients. It consisted of implantation of a transmural metallic stent under single endoscopic guidance. In one patient the stent was not released and aspiration drainage was performed. The nine patients who had stents implanted have presented no recurrences, but the patient who underwent aspiration drainage presented recurrence in the body of the pancreas. The main complication was migration of the stent into the pseudocyst cavity which occurred in one patient and which required a second endoscopic procedure to remove the stent.


Transmural drainage of pancreatic pseudocysts through placement of stents is a safe, effective and minimally invasive technique for the treatment of pancreatic pseudocysts.
