What We Know So Far About ECG for Pancreatic Pseudocysts

<b>Background:</b> Endoscopic cysto-gastrostomy (ECG) has become the treatment of choice for pancreatic pseudocysts (PPCs). Endoscopic drainage of PPCs requires the creation of an anastomosis between the lumen of the PPCs and the lumen of the gastrointestinal tract. Various types of stents are used for this purpose. The aim of the study is to compare the indications, quantity, and results of using double pigtail plastic stents (DPPSs) and lumen-apposing fully covered metal stents (LAMSs) in ECG. <b>Methods:</b> A retrospective analysis was conducted of 39 patients (24 men, 15 women) treated for PPCs in the Department of Digestive Tract Surgery and the Department of Gastroenterology and Hepatology between October 2018 and February 2023. The mean age of patients was 51.13 (28-77). Data about etiology, cyst diameter, type, and complications of the stents were collected. <b>Results:</b> DPPSs were placed in smaller cysts (108 vs. 140 millimeters, <i>p</i> = 0.04) and were maintained for a longer duration compared to LAMSs (106 vs. 34 days, <i>p</i> = 0.001). Cyst recurrence was reported less frequently in patients with a LAMS (0 (0%) vs. 4 (19.05%), <i>p</i> = 0.05) and the therapeutic success was non-significantly higher in the LAMS group compared to the DPPS group (100% vs. 85.71%), <i>p</i> = 0.095. <b>Conclusions:</b> Both DPPSs and LAMSs are characterized by high therapeutic success and low complication rates in patients undergoing ECG for PPCs.
