[Enterovesical fistula secondary to leiomyosarcoma]

Area of Science:

• Gastroenterology
• Urology
• Oncology

Background:

• Enterovesical fistulas are rare abnormal connections between the intestine and urinary bladder.
• Leiomyosarcoma is a rare malignant mesenchymal tumor that can occur in various organs.

Observation:

• An elderly male patient presented with a one-year history of recurrent urinary tract infections.
• Diagnostic evaluation revealed an enterovesical fistula.
• The fistula was found to be caused by leiomyosarcoma infiltrating the intestinal wall and urinary bladder.

Findings:

• The patient underwent surgical management for the enterovesical fistula.
• Despite residual tumor post-operatively, the patient survived for three years.
• No further antineoplastic treatment was administered during this period.

Implications:

• This case highlights an unusual presentation of leiomyosarcoma leading to enterovesical fistula.
• The long-term survival of the patient despite residual disease suggests potential for favorable outcomes in select cases.
• Further research into the management and prognosis of leiomyosarcoma-induced enterovesical fistulas may be warranted.
