Transanal minimally invasive surgery (TAMIS) for rectal cancer with transabdominal and transrectal ICG-guided sentinel node
Transanal minimally invasive surgery (TAMIS) for rectal cancer is gaining interest, with the objective of maximum sparing for physiological functions. Although this approach may be considered appropriate for treating stage T1m tumors, a large proportion of T1sm and T2 tumors could well benefit from this. The greatest limitation to the application of TAMIS is represented by the difficulty of obtaining an adequate lymph node sample of the mesorectum. The use of indocyanine green (ICG) has recently been suggested as a possible lymph node marker after peritumoral injection. The case described in this video presents an innovative proposal for the detection and removal of lymph nodes draining a tumor of the lower rectum, with the aim of obtaining an adequate lymph node staging. After endoscopic peritumoral ICG injection, we proceeded to the search and removal of sentinel lymph nodes both with a laparoscopic transabdominal approach and with a transrectal approach (after specimen removal). If validated in a prospective series, this technique could represent the best lymph node harvesting strategy during TAMIS for early stage rectal cancer.
