Abstract

Background: Distal bowel perforation by peritoneal catheter (BPPC) is a rare complication following ventriculoperitoneal shunt (VPS) placement for the treatment of hydrocephalus. In some cases, BPPC may present with extrusion through the anus and can occur years after VPS placement.

Observations: The authors report the case of a 30-year-old woman who had a VPS placed 8 years prior and found a catheter protruding from her rectum. Having pulled out 1 foot of catheter, she presented to the hospital where the shunt was externalized before concurrent VPS removal and laparotomy to repair the bowel perforation.

Lessons: BPPC with anal extrusion is a rare complication of VPS that can occur years after shunt placement and can present with a broad array of symptoms. BPPC should remain on the differential for people with VPS and systemic symptoms for the duration of their lives. https://thejns.org/doi/10.3171/CASE25365.

无并发症脑室腹腔分流放置后8年直肠导管糜烂：说明性病例。

背景：腹膜导管远端肠穿孔（BPPC）是脑室-腹膜分流术（VPS）治疗脑积水后罕见的并发症。在某些情况下，BPPC可能表现为通过肛门挤压，并可能在VPS放置数年后发生。观察：作者报告了一名30岁妇女的病例，她在8年前放置了VPS，发现导管从她的直肠突出。在拔出1英尺的导管后，她来到医院，在同时移除VPS和开腹修复肠穿孔之前，分流器被取出。结论：BPPC合并肛门挤压是VPS的罕见并发症，可在分流器放置数年后发生，并可呈现多种症状。对于有VPS和全身性症状的患者，BPPC应在其一生中保持差异。https://thejns.org/doi/10.3171/CASE25365。
