Overview
Reliable nutrition past the stomach.
A feeding jejunostomy is a small feeding tube placed surgically into the proximal jejunum — about 30 to 40 cm beyond the ligament of Treitz. It delivers formula, water, and medications directly into the small bowel, bypassing the mouth, esophagus, and stomach. The tube exits the abdominal wall on the left upper quadrant, secured at the skin. Most J-tubes are 12–16 French silicone catheters that lie flat against the skin when not in use.
J-tubes are chosen when feeding into the stomach is not safe or not possible. The most common scenarios are after esophagectomy or total gastrectomy (where there is no stomach to feed into, or where the gastric conduit needs time to heal), gastric outlet obstruction from cancer or chronic disease, severe aspiration that has failed gastrostomy feeding, and the planned long-term enteral access for patients with head and neck cancer, neurologic disease, or other conditions that prevent safe oral intake.
Who is a candidate?
Patients undergoing esophagectomy or total gastrectomy are the most common candidates — we place a J-tube at the same operation to support nutrition during the long recovery and conduit-healing period. Patients with gastric outlet obstruction from advanced gastric or pancreatic cancer, where palliative feeding past the obstruction is needed, are another common indication. Patients with chronic dysphagia or aspiration who have failed G-tube feeding because of reflux into the lungs benefit from jejunal feeding. Long-term enteral access for patients with head and neck cancer, advanced Parkinson's or ALS, or other neurologic conditions is also a frequent indication.
How we perform it
When placed at the same time as a larger operation, the J-tube is part of that operation's closure. When done as a standalone laparoscopic case, we use two or three small ports. We identify the ligament of Treitz, count 30–40 cm down the jejunum, and choose a tube exit site on the left upper abdominal wall. The tube is brought through the abdominal wall and into the jejunum. We create a serosal tunnel over 4–5 cm of the tube (the Witzel technique) so leakage at the tube entry is minimized. The jejunum is then tacked to the abdominal wall at three points around the tube to prevent volvulus and tube migration. The tube is secured at the skin with a bumper or sutures. Total time for a standalone laparoscopic placement is 45 to 75 minutes.
Recovery and tube use
Tube use can typically start within 12–24 hours. We begin with trophic feeds — a small volume to wake up the gut — and advance the rate every 8–12 hours toward the goal volume set by the nutrition team. Most patients reach full goal feeds within 3–5 days. Before discharge, you (or your caregiver) are taught tube use: pump setup, formula preparation, water flushes, medication administration, site care, and troubleshooting. Home health, a nutrition supplier, and outpatient nutrition follow-up are set up before you leave. We see you at 2 weeks for site check and to address any questions.
Why Florida Surgical
J-tubes are deceptively simple — but tube position, securement, and counseling around tube use are what make the difference between a problem-free tube and frequent ER visits. We place J-tubes at the time of esophagectomy and gastrectomy for our own oncology patients, and we accept standalone placement referrals from gastroenterology, oncology, and palliative care. We work closely with home health and outpatient nutrition to ensure the support a patient needs is in place before discharge.
Frequently asked questions
Why a jejunostomy instead of a stomach feeding tube?
A jejunostomy is chosen when feeding into the stomach is unsafe or impossible — after esophagectomy or total gastrectomy, when there is gastric outlet obstruction, when reflux into the lungs has caused aspiration with prior G-tubes, or when a pancreatic, biliary, or duodenal anatomy makes gastric feeding problematic. A J-tube delivers nutrition past the stomach and pylorus directly into the small bowel.
Can the J-tube be placed laparoscopically?
Yes — in elective cases without prior hostile abdominal surgery, the J-tube can be placed laparoscopically with two or three small ports. The jejunum is identified, the tube is inserted using a Witzel tunnel or purse-string technique, and the jejunum is tacked to the abdominal wall to prevent tube dislodgement or volvulus. Most J-tubes placed at the same operation as an esophagectomy or gastrectomy go in through the existing open approach.
When can I start using the tube?
Trophic feeds (small volume to wake up the gut) usually start within 12–24 hours. We slowly advance the rate over 3–5 days to a goal target set by nutrition. Most patients are tolerating full goal feeds by discharge. We work with home health and a nutrition team to set up your pump, formula delivery, and supplies before you leave the hospital.
How long does the tube stay in?
As long as you need enteral access. For post-esophagectomy patients, the tube usually stays 6–8 weeks until oral intake is reliable. For long-term enteral nutrition (chronic dysphagia, neurologic disease, head and neck cancer survivors who cannot swallow), the tube can remain for years and is exchanged periodically. Tube removal is straightforward in clinic when no longer needed — the tract closes on its own within a few days.
What are the risks?
Risks include tube dislodgement (the most common — securement matters), tube blockage (prevented with water flushes), site infection, leakage around the tube, and rare but serious problems including volvulus of the jejunum around the tube and bowel injury. We tack the jejunum to the abdominal wall during placement specifically to prevent volvulus. Site care and prompt attention to early signs of trouble prevents most issues.
