Jejunal feeding often is preferable to gastric feeding, particularly in the following situations: high risk for aspiration; gastric resection (partial or total); gastric pull-up; gastric outlet obstruction; obstructed or nonfunctioning gastrojejunostomy; and gastric dysmotility. The technique of placing a thin tube through a gastrostomy tube and pulling it endoscopically into the proximal jejunum allows delivery of nutrients into the jejunum. The results of this technique, however, have been poor. The direct percutaneous endoscopic jejunostomy technique allows placement of tubes directly in the jejunum with a success rate of around 85% and a minimal complication rate which is comparable to that of PEGs.
空肠喂养通常比胃喂养更可取，尤其是在以下情况：误吸风险高；胃切除术（部分或全部）；胃上提术；胃出口梗阻；胃空肠吻合口梗阻或无功能；以及胃动力障碍。通过胃造口管插入细管并在内镜引导下将其拉入空肠近端的技术可将营养物质输送至空肠。然而，该技术的效果不佳。直接经皮内镜下空肠造口术可将管子直接放置在空肠中，成功率约为85%，并发症发生率极低，与经皮内镜下胃造口术相当。
