Endoscopically placed biliary stents are a well-established procedure for the treatment of benign and malignant causes of obstructive jaundice. A plastic stent is usually inserted in patients with obstructive jaundice due to pancreatic cancer as a short-term procedure. Stent migration has been reported as a complication, although in most cases the stent will pass through or remain in the bowel lumen for a period of time. In rare cases, the stent may cause sigmoid perforation and pelvic abscess formation, especially in patients with sigmoid diverticulae or abdominal adhesions due to previous surgery. We present a patient with sigmoid perforation and pelvic abscess due to distal migration of a biliary stent placed to decompress a pancreatic head carcinoma.
内镜下放置胆道支架是治疗梗阻性黄疸良性和恶性病因的成熟方法。对于因胰腺癌导致梗阻性黄疸的患者，通常会插入塑料支架作为短期治疗手段。尽管在大多数情况下支架会在一段时间内通过或留在肠腔内，但支架移位已被报道为一种并发症。在极少数情况下，支架可能导致乙状结肠穿孔和盆腔脓肿形成，尤其是在患有乙状结肠憩室或因既往手术导致腹部粘连的患者中。我们报告了一例因放置胆道支架以缓解胰头癌导致的远端移位而出现乙状结肠穿孔和盆腔脓肿的患者。
