Introduction and aims
PEG removal in head and neck cancer patients (HNCPs) is performed after treatment, in case of disease remission and after adequate oral intake is resumed. The PEG tract usually closes spontaneously within 2–3 days. Persistent gastrocutaneous fistula (GCF) is a rare complication after PEG tube removal and is characterized by the persistence of gastric leakage through the fistulous tract for more than 1 month. Our main goal was to access the incidence and the success of a treatment algorithm for GCF in HNCPs.
Methods
Retrospective unicentric study of HNCPs referred for PEG removal between 2014 and 2018. The patients with GCF were selected and their sequential treatment was reviewed.
Results
In 331 patients with PEGs removed, 19 (5.7%) GCFs were documented. Medical therapy (4–8 weeks) was performed with clinical success (definitive closure of the GCF) in 12 (63.2%) patients. The remaining seven patients required endoscopic or surgical treatment. In four, endoscopic treatment had technical and clinical success (in three patients with fulguration of the gastric leak edges with argon plasma coagulation, silver nitrate in the path and external orifice, and closure of the internal orifice with hemoclips and in one with an over-the-scope-clip). Only three patients underwent surgery, one due to clinical failure of sequential endoscopic therapy and two had direct surgery.
Conclusion
GCF occurs rarely after PEG removal in HNCPs. Medical therapy is usually effective and should be maintained for at least 8 weeks. Endoscopic therapy is an effective second-line option with and surgery rarely required.
