Benign duodenal tumours are rare and less common than malignant tumours. They comprise a wide variety of pathologies. Schwannoma is an ectodermal neoplasm arising from the nerve sheath that envelops axons. A duodenal location is extremely rare. Therapy consists in the radical excision of the tumour. Our aim was to describe a minimally invasive technique used for the excision of duodenal schwannoma, so that a laparotomy has been avoided.


A laparoscopic operation under general anaesthesia was undertaken with the patient in supine position with the legs abducted. No macroscopic peritoneal seedling was found. Therefore, a laparoscopic Kocher maneuver was performed. The retroperitoneum was entered using the harmonic scalpel and the dissection extended beyond the vena cava and the duodenum. The location and the size of the lesion have been confirmed using an intraoperative endoscopic ultrasound examination. The excision of the lesion was performed by use the harmonic scalpel. Then, the duodenal wall was sutured by use endoscopic stitches. The resected lesion was then placed in a retrieval bag and extracted through the port incision. Operating time was 300 min and blood loss 200 ml.


The postoperative course was uneventful. Histological findings showed a benign schwannoma.


The minimally invasive technique may be a valid alternative to open surgery in the treatment of benign duodenal tumors.
