Abstract

Background: The presence of debris within a pseudocyst may impair success of endoscopic drainage. Objective: To compare the clinical outcomes and adverse-event rates of EUS-guided pseudocyst drainage with and without a nasocystic drain for the management of pancreatic pseudocysts with viscous solid debris-laden fluid. Design: Retrospective study. Setting: Single, tertiary-care referral center. Patients: Consecutive patients with pancreatic pseudocysts managed by EUS-guided drainage: those with solid debris who underwent drainage via nasocystic drains alongside stents (n = 63) and those with solid debris who underwent drainage via transmural stents only (n = 24). Intervention: Drainage via nasocystic drains alongside stents or drainage via transmural stents only. Main Outcome Measurements: The primary outcomes were short-term success and long-term success of the procedures. The secondary outcomes were procedure-related adverse events and reintervention. Results: The patients with viscous solid debris-laden fluid whose pseudocysts were drained by both stents and nasocystic tubes had a 3 times greater short-term success rate compared with those who had drainage by stents alone (P =.03). On 12-month follow-up, complete resolution of pseudocysts with debris drained via stents alone was less (58%) compared with those with debris who underwent drainage via nasocystic drains alongside stents (79%; P =.059). The rate of stent occlusion was higher in cysts with debris drained by stents alone (33%) compared with those drained via nasocystic drains alongside stents (13%; P =.03). Limitations: Retrospective design; limited sample size. Conclusion: In patients with pseudocysts with viscous debris-laden fluid, EUS-guided drainage by using a combination of a nasocystic drain and transmural stents improves clinical outcomes and lowers the stent occlusion rate compared with those who underwent drainage via stents alone.
