Percutaneous endoscopic gastrostomy is used for long-term nutritional support and can be performed with relatively few complications. We describe a patient in whom the internal bumper eroded into the stomach wall and was completely covered by gastric epithelium 11 months after gastrostomy tube placement. The gastrostomy tube itself was patent, and the end still protruded into the lumen of the stomach so that tube feeding was not impaired. Endoscopy, in combination with passage of Savary dilators over a guidewire, was safely used to remove the gastrostomy tube and buried bumper. We recommend this approach in patients with the "buried bumper" syndrome to prevent continued tube migration into the gastric and abdominal walls.
经皮内镜下胃造口术用于长期营养支持，并发症相对较少。我们描述了一名患者，其内置缓冲器在胃造口管置入11个月后侵蚀入胃壁并被胃上皮完全覆盖。胃造口管本身通畅，末端仍突出于胃腔内，因此管饲未受影响。内镜检查结合在导丝上通过Savary扩张器，被安全地用于移除胃造口管和埋藏的缓冲器。对于患有“埋藏缓冲器”综合征的患者，我们推荐这种方法以防止胃造口管继续向胃壁和腹壁内迁移。
