PEG use in patients with squamous cell carcinoma.

Area of Science:

• Gastroenterology
• Oncology

Background:

• Persistent gastrocutaneous fistulas after Percutaneous Endoscopic Gastrostomy (PEG) can occur.
• Patients with a history of squamous cell carcinoma (SCC) of the esophagus or nasopharynx are a specific population.
• The use of an Ovesco Endoscopic Clipping System (OTSC) may be a factor in fistula management.

Purpose of the Study:

• To raise awareness of tumor seeding in gastrocutaneous fistulas.
• To identify patient groups at higher risk for this complication.
• To provide guidance on appropriate Percutaneous Endoscopic Gastrostomy (PEG) techniques.

Main Methods:

• Review of clinical cases and relevant literature.
• Analysis of factors contributing to fistula complications.
• Discussion of endoscopic procedural risks.

Main Results:

• Tumor seeding along the fistula tract is a potential complication.
• Patients with prior esophageal or nasopharynx SCC are particularly susceptible.
• The "pull technique" for PEG placement is identified as a risky method in this context.

Conclusions:

• Clinicians should suspect tumor seeding in persistent gastrocutaneous fistulas in patients with a history of SCC.
• The "pull technique" for PEG placement should be avoided in patients with a history of esophageal or nasopharynx SCC.
• Careful consideration of PEG placement methods is crucial for preventing tumor seeding.
