Jejunostomy feeding delivers enteral nutrition beyond the stomach, and in some cases beyond the duodenum. This route can be useful when impaired stomach emptying or another gastric problem prevents effective delivery through the usual pathway. By placing formula directly into the jejunum, clinicians can continue using the intestinal route for nutritional support while avoiding the affected upper gastrointestinal region.
The jejunum is the middle section of the small intestine and supports intestinal absorption after formula enters through the tube. This allows nutrients to reach an absorptive portion of the gastrointestinal tract without first passing through the mouth or stomach. The approach therefore maintains enteral nutrition in situations where upper gastrointestinal passage is unsuitable or insufficient.
The main distinction is the location of delivery. Gastric feeding places nutrition in the stomach, whereas a jejunostomy tube delivers it directly into the jejunum and may bypass the stomach and duodenum. This difference matters when stomach emptying is impaired, obstruction affects the upper route, or a selected postoperative condition makes gastric feeding less suitable.
Clinicians may consider jejunostomy when gastric feeding is unsafe or ineffective, particularly with impaired stomach emptying, obstruction, or selected postoperative conditions. The procedure can provide a way to maintain nutritional management while addressing limitations in the usual upper gastrointestinal route. Its use depends on the patient’s clinical circumstances and the intended need for access.
A feeding jejunostomy creates access from the abdominal wall into the jejunum through a tube. That access can support delivery of enteral formulas and medications when the upper gastrointestinal route is unsuitable. Depending on the clinical purpose, jejunal access may also be used for decompression or drainage, rather than nutrition alone.
Post-procedure monitoring should include the tube site and the tube’s position, with attention to infection, displacement, leakage, and other complications. These problems can interfere with nutrition, medication delivery, decompression, or drainage. Ongoing observation helps clinicians identify access-related difficulties early and determine whether the jejunostomy continues to meet its intended clinical purpose.
