CHACALTANA MENDOZA, Alfonso et al. Efficacy and safety of echoendoscopy drainage of liquid peripancreatic collections in a reference hospital. Rev. gastroenterol. Perú [online]. 2020, vol.40, n.1, pp.46-51. ISSN 1022-5129.


Endoscopic ultrasound (EUS) guided drainage is considered the best option for peripancreatic fluid collections drainage. There are no previous reports in our country of this type of endoscopic therapy.


To detail the characteristics, efficacy and safety of EUS-guided drainage of peripancreatic fluid collections at Edgardo Rebagliati Martins National Hospital.

Materials and methods:

We carried out a retrospective cross-sectional study of all patients who underwent EUS-guided drainage of symptomatic peripancreatic fluid collections. Demographics, procedure-related endosonographic features and devices used were analyzed. We assessed the effectiveness with technical and clinical success rate. Clinical safety was assessed based on major immediate and delayed adverse events. Basic descriptive statistics was used.


A total of 17 patients (9 women, 52.9% and 8 men, 47.1%) with peripancreatic fluid collections (10 pseudocysts and 7 walled-off necrosis) underwent EUS-guided drainage. The median age of the patients was 59 years (range 26 - 72 years). The mean diameter of the fluid collections was 14.8 cm (range 8-24 cm). Transgastric route was used in 16 cases (94.1%) and transduodenal route in 1 case (5.9%). Plastic stent (6 cases), biliary self expanding metal stent (4 cases) and lumen apposing stent (7 cases) were used. The technical success rate was 100% (17 patients), while clinical success rate was 70.6% (12 patients). Adverse events occurred in 41.2%: infection (2 cases), perforation, bleeding, plastic stent occlusion, stent migration into the collection cavity and out of the collection cavity (1 case each one). Surgical management of adverse events was necessary in 3 cases, while the 4 other cases only required medical - endoscopic management.


EUS-guided drainage of peripancreatic fluid collections have a high technical and clinical success rate with a low percentage of adverse events.
