Laparoscopic radioisotope-guided sentinel lymph node mapping and excision of the rectum—an experimental study

Abstract

Minimal invasive mapping and excision of SLN of the rectum using a RI is feasible. The sensitivity for detecting SLN was high (93%). The application of this procedure on humans seems to be possible.

Rectum-conserving surgery in the era of chemoradiotherapy

“…Although the technique has been studied widely in colorectal cancer as an adjunct to upstage tumours undergoing radical surgery, no clinical study has yet investigated the technique in a preoperative setting. Only one study has assessed SLNM as a preoperative staging modality in a porcine model86. A mixture of 99m Tc and patent blue V dye was administered endoscopically into the rectum of 30 pigs.…”
