    Abstract:
    BACKGROUND: Endoscopic drainage (ED) and percutaneous drainage (PD) have largely replaced surgical drainage as the initial approach for symptomatic pseudocysts. However, there are few studies comparing ED and PD. OBJECTIVE: To compare the outcomes of ED and PD for symptomatic pseudocysts. DESIGN: Retrospective cohort study. SETTING: Academic center. PATIENTS: Adult patients with symptomatic pseudocysts within ≤ 1 cm of the gastric or duodenal wall who underwent ED or PD between 1993 and 2011. Patients with walled-off pancreatic necrosis were excluded. INTERVENTION: ED or PD. MAIN OUTCOME MEASUREMENTS: Rates of technical success, procedural adverse events, clinical success, reinterventions, and failure. Other outcomes included the length of hospital stay and number of follow-up abdominal imaging studies. RESULTS: There were 81 patients, 41 who underwent ED and 40 who underwent PD, with no differences in age, sex, and comorbidity between the 2 groups. There were no differences in the rates of technical success (90.2% vs 97.5%; P = .36), adverse events (14.6% vs 15%; P = .96), and clinical success (70.7% vs 72.5%; P = .86) between ED and PD, respectively. Patients who underwent PD had higher rates of reintervention (42.5% vs 9.8%; P = .001), longer length of hospital stay (14.8 ± 14.4 vs 6.5 ± 6.7 days; P = .001), and median number [quartiles] of follow-up abdominal imaging studies (6 [3.25, 10] vs 4 [2.5, 6]; P = .02) compared with patients who underwent ED. LIMITATIONS: Single center, retrospective study. CONCLUSION: ED and PD have similar clinical success rates for symptomatic pseudocysts. However, PD is associated with significantly higher rates of reintervention, longer length of hospital stay, and increased number of follow-up abdominal imaging studies.
