OBJECTIVE
The aim of this prospective study was to compare the feasibility, technical success rate and complication between single-step endo-ultrasonography (EUS)-guided and two-step EUS-guided drainage technique for symptomatic pancreatic pseudocyst (PP).
METHODS
Twenty-one PP patients with clear intra-cystic fluid that needed to be drained were divided into two groups, depending on the availability of the therapeutic echoendoscope at the time of the procedure: Group 1 (13 patients) underwent a single-step EUS-guided endoscopic drainage and Group 2 (8 patients) underwent a two-step EUS-guided drainage technique.
RESULTS
In Group 1 immediate technical success was achieved in 92.3% (12/13); two patients had recurrent PP and both were successfully treated by a second EUS-guided drainage. Clinical success was achieved in all cases. In Group 2 technical success was achieved in 75.0% of the patients (6/8). One patient (12.5%) bled 36 h after the procedure. Five out of 6 patients had long-term success. Clinical success was significantly greater in Group 1 (P < 0.05).
CONCLUSION
The technique of single-step EUS-guided drainage was superior to the technique of a two-step EUS-guided drainage technique for PP drainage.
目的
本前瞻性研究旨在比较单步内镜超声（EUS）引导与两步 EUS 引导引流技术治疗有症状胰腺假性囊肿（PP）的可行性、技术成功率和并发症。
方法
将 21 例需要引流的有明确囊内液体的 PP 患者分为两组，根据操作时治疗性超声内镜的可用性：组 1（13 例）行单步 EUS 引导下内镜引流，组 2（8 例）行两步 EUS 引导下引流技术。
结果
组 1 中即刻技术成功率为 92.3%（12/13）；2 例患者出现复发性 PP，均通过第二次 EUS 引导下引流成功治疗。所有病例均获得临床成功。组 2 中技术成功率为 75.0%（6/8）。1 例患者（12.5%）在术后 36 小时出血。6 例中有 5 例长期成功。组 1 的临床成功率显著高于组 2（P<0.05）。
结论
单步 EUS 引导引流技术优于两步 EUS 引导引流技术，适用于 PP 引流。
