Colocutaneous fistula due to polypropylene mesh

Area of Science:

• Gastroenterology
• Surgical Innovation
• Medical Device Complications

Background:

• Fistulae formation is a known complication of prosthetic mesh when placed near hollow organs.
• While enterocutaneous fistulae are documented, large bowel involvement is less common.
• Accurate recognition and management of these severe complications are critical.

Observation:

• A patient developed a colocutaneous fistula following recurrent incisional hernia repair.
• The fistula was attributed to fragmentation of the implanted polypropylene mesh.
• The mesh fragments eroded into the sigmoid colon, leading to the fistula.

Findings:

• This case demonstrates a rare instance of polypropylene mesh fragmentation causing a colocutaneous fistula.
• The complication occurred after a standard procedure for recurrent incisional hernia.
• The sigmoid colon was directly affected by the eroded mesh fragments.

Implications:

• Highlights the potential for severe gastrointestinal complications from polypropylene mesh, even with large bowel involvement.
• Underscores the need for vigilance in diagnosing mesh-related fistulae, especially in cases with large bowel symptoms.
• Suggests a need for further investigation into mesh degradation and long-term safety profiles in hernia repair.
