ABSTRACT
BACKGROUND
Endoscopic submucosal dissection (ESD) can be used for the en-bloc removal of superficial rectal lesions; however, the lack of a traction system makes the procedure long and difficult in the presence of extensive lesions.
CASE SUMMARY
A large polyp occupying 2/3 of the rectal circumference and extending 5 cm in length was removed by ESD with the help of laparoscopic forceps introduced via trans-anal rectoscopic assisted minimally invasive surgery, a disposable platform designed to aid in transanal minimally invasive surgery. Traction of the polyp by forceps during the operation was dynamic, and applied at various points and in various directions. The polyp was removed en-bloc without complications in 1 h and 55 min. A sigmoidoscopy performed 50 d later showed normal healing without polyp recurrence.
CONCLUSION
The technique presented here could overcome the issues caused by lack of traction during ESD for rectal lesions.
