TRANSANAL TOTAL MESORECTAL EXCISION OF RECTAL CANCER TREATMENT

Purpose: To evaluate the early results of the feasibility and safety on technology and oncologic transanal total mesorectal excision (down to up).
Materils and method: Prospective study from 2012 to 2018.
Patients: 23 rectum adenocarcinoma staging T ≤ 3, N ≤ 1, M0 were operated using one of two modalities Hybrid NOTES (A) and NOTES (B).
Results: Twenty three patients with Rectal cancer were sucessfully in total mesorectal excision performed by Hybrid NOTES and NOTES procedures. Three cases in group NOTES had per-operative complications such as bleeding or urethra injury required one or two trocarts for assistance, no conversion to open surgery and no mortality. The operation time: group A (Hybrid NOTES): 190 ± 47 (120-280) mins; group B (NOTES): 258 ± 40 (190-300) mins. The hospital stay: 9 ± 2.7 (4-19) day.
Conclusions: transanal total mesorectal excision (down to up) endoscopic surgery (NOTES) and Hybrid NOTES is feasible and safe.However, a study in a large number of patient and long follow-up is necessary.
