Aim: The aim of this stud was to present a case with uncommon rectal schwannoma undergoing robotic transanal surgery.
Background: Gastrointestinal schwannomas are uncommon and in particular, rectal schwannomas are even rarer. It is well established that schwannomas, nerve sheath tumors originating from Schwann cells, appear more frequently in the stomach and in the small intestine. Postoperative staining positive for S-100 protein and negative for smooth muscle markers, such as actin and desmin is essential for diagnosis. Traditional surgery requires resection of the rectum and patients are faced with longer hospital stay but robotic-assisted transanal approach enhanced faster recovery and shorter hospital stay.
Case Description: A 47-year-old female was found to have one rectal tumor during digital rectal examination performed as part of a health examination. Colonoscopy showed one submucosal mass with intact mucosa with hard consistency by forceps touching at 10 cm above anal verge. Transanal robotic-assisted tumor excision was done with final pathology showing rectal schwannoma. Conclusion: Robotic-assisted transanal approach for local excision of rectal tumors with low risk of malignancy can be performed safely.
