Intestinal Dysmotility and the Risk of Volvulus Following Omega-jejunostomy Tube Placement in Children

jpedsurg.org

Gastric dysmotility complicates enteral feeding in children, often requiring distal feeding access. While nasoduodenal and gastrojejunostomy tubes are common, frequent dislodgements necessitate hospital visits for fluoroscopic-guided replacement, exposing children to radiation and potential anesthesia risks. The omega-jejunostomy (OJ) tube was developed as a simpler alternative to roux-en-Y feeding jejunostomy, allowing easy at-home tube changes after tract maturation. Despite nearly two decades of use, OJ-tube placement remains poorly characterized.

In brief

This article examines omega-jejunostomy tube placement as an alternative feeding access method for children with gastric dysmotility who require distal enteral nutrition. The technique offers advantages over traditional approaches by enabling home-based tube changes, though volvulus risk and long-term outcomes remain incompletely understood despite nearly 20 years of clinical use.

Omega-jejunostomy tubes allow caregivers to replace feeding tubes at home after tract maturation, avoiding repeated hospital visits.
Traditional nasoduodenal and gastrojejunostomy tubes require frequent fluoroscopic replacements, exposing children to radiation and anesthesia.
OJ tubes offer a simpler surgical alternative to roux-en-Y jejunostomy for children with gastric dysmotility requiring distal feeding.
Despite two decades of clinical use, omega-jejunostomy tube placement outcomes remain inadequately studied and characterized.
