Usefulness of Preoperative Endoscopic Fluorescent Clip Marking in Laparoscopic Gastrointestinal Surgery.

BACKGROUND/AIM: Precise tumor localization during gastrointestinal surgery improves curability and function preservation. We investigated the efficacy of preoperative endoscopic fluorescent clip marking using a Zeoclip FS with built-in near-infrared fluorescent resins in delineating gastrointestinal cancer for surgery.

PATIENTS AND

METHODS

We evaluated the intraoperative visibility of the Zeoclip FS using a VISERA ELITE 2 and the short-term outcomes of 37 cancer patients (colorectal, n=23; gastric, n=14) who underwent preoperative fluorescent clip marking.

RESULTS

The study included 23 male and 14 female subjects with a mean age of 73 years (range=39-87 years). Thirty-three patients (89.1%) exhibited clear fluorescent clip marking and easily determined transection lines. Fluorescence was not observed in 1 sigmoid colon cancer patient (2.7%), who required a colonic stent for preoperative obstruction. Three patients (8.1%) required additional procedures for fluorescence visualization.

CONCLUSION

Endoscopic fluorescent clip marking can delineate tumors well for determining the extent of resection.
