Differential Diagnosis for Leaking G-tube
Single Most Likely Diagnosis
- G-tube site infection or abscess: This is often the most common cause of a leaking G-tube, as the site can become infected, leading to purulent discharge and leakage around the tube.
Other Likely Diagnoses
- G-tube dislodgement or malposition: If the G-tube is not properly placed or becomes dislodged, it can lead to leakage around the site.
- Fistula formation: A fistula can form between the stomach and the skin, causing leakage of gastric contents around the G-tube site.
- G-tube balloon malfunction: If the balloon that secures the G-tube in place is not functioning correctly, it can lead to leakage.
Do Not Miss Diagnoses
- Necrotizing fasciitis: Although rare, this is a life-threatening condition that can occur if the infection at the G-tube site spreads and becomes severe.
- Perforated viscus: A perforation in the stomach or intestine can cause leakage of contents into the abdominal cavity, leading to severe infection and potentially life-threatening complications.
- Gastric outlet obstruction: An obstruction in the stomach can cause increased pressure, leading to leakage around the G-tube site.
Rare Diagnoses
- Tumor erosion: A tumor in the stomach can erode through the wall and cause a fistula, leading to leakage around the G-tube site.
- Gastrocutaneous fistula due to other causes: Other conditions, such as Crohn's disease or ulcerative colitis, can cause a fistula to form between the stomach and the skin, leading to leakage.
- Abdominal wall hernia: A hernia in the abdominal wall can cause intestinal contents to leak around the G-tube site.
