Background:
Rectal gastrointestinal stromal tumors (GISTs) complicate surgical approaches because of their anatomical position. We herein report a patient with rectal GIST on the anterior wall of the lower rectum, hat was successfully resected using a transperineal approach.
Case Presentation:
This report describes a unique case of a 73-year-old man who was diagnosed with rectal GIST on the anterior wall of the lower rectum. The tumor was located within 3 cm of the anal verge, a location that would require highly invasive surgery. A transperineal approach was planned to preserve the anal function. Under general anesthesia, the patient was placed in a lithotomy position and a Mercedes-Benz incision was made in the perineum. Excision of the tumor was performed. The post-operative course was uneventful, and the patient remained free from recurrence.
Conclusion:
This case highlights the importance of performing minimally invasive and safe surgery. With some surgical refinements, a transperineal approach may be an option for surgical procedures in patients with rectal GIST on the anterior wall of the lower rectum.
