Transanal Minimally Invasive Surgery for Rectal Neuroendocrine Tumor

2018 
: A 57-year-old woman was admitted to our hospital due to a suspected rectal tumor at previous doctor. Colonoscopy showed a submucosal tumor with 8mm yellowish protrusions and smooth surfaces in the rectum, 5 cm from the anal verge. Endoscopic ultrasonography showed the appearance of the internal portions of the tumor to be relatively uniform in low echoic imagery. The tumor was located in the second to third layer. Histopathological findings showed neuroendocrine tumor- G1. We performed transanal minimally invasive surgery with GelPOINT®Path. Under general anesthesia, complete fullthickness excision of the rectal lesion was performed. Primary closure was accomplished using a 3-0 braided absorbable suture. The operation duration was 24 min; blood loss was very little in this case. The patient recovered uneventfully and was discharged 2 days after the operation. There was no anorectal dysfunction and no local and distant recurrence during the postoperative follow-up of 1 year 3 months. Transanal minimally invasive surgery with GelPOINT®Path was an effective treatment for the safe removal of small rectal tumor indicated for local resection.
