To compare the results for endoscopic ultrasound (EUS)-guided drainage of clear fluid pancreatic pseudocysts with the results for abscess drainage.
All patients referred for endoscopic drainage of a fluid collection were prospectively included. The outcome was recorded.
Altogether 26 pseudocysts or abscesses were treated in 25 (6 female) patients. One endoscopist performed the procedures. Non-infected pseudocysts were present in 15 patients and 10 patients had infected fluid collections. The cyst size ranged between 28 cm × 13 cm and 5 cm × 5 cm. The EUS drainage was successful in 94% of the pseudocysts and in 80% of the abscesses (P = 0.04). The complication rate in pseudocysts was 6% and in abscesses was 30% (P = 0.02). Recurrence of a pseudocyst occurred in one patient (4%) after 6 mo; the patient was successfully retreated.
EUS-guided drainage of pseudocysts is associated with a higher success rate and a lower complication rate compared with abscess drainage.
比较内镜超声(EUS)引导下引流澄清液体胰腺假性囊肿与脓肿引流的结果。
所有因液体积聚而接受内镜引流的患者均被前瞻性纳入。记录结果。
共有 25 名(6 名女性)患者的 26 个假性囊肿或脓肿接受了治疗。一名内镜医生进行了这些操作。15 名患者存在非感染性假性囊肿,10 名患者存在感染性积液。囊肿大小范围为 28cm×13cm 至 5cm×5cm。EUS 引流在 94%的假性囊肿和 80%的脓肿中取得成功(P=0.04)。假性囊肿的并发症发生率为 6%,脓肿为 30%(P=0.02)。1 例假性囊肿患者(4%)在 6 个月后复发;该患者经成功再次治疗。
与脓肿引流相比,EUS 引导下引流假性囊肿的成功率更高,并发症发生率更低。
