Optical Biopsy for Peritoneal Nodules in Colorectal Patients

Colorectal Cancer Clinical Trial

Official title: Use of Probe-based Confocal Laser Endomicroscopy to Perform Optical Biopsy for Peritoneal Nodules in Colorectal Cancer Patients During Surgery

Status Recruiting

Clinical Trial Summary

During surgery, peritoneal metastasis is typically confirmed pathologically through resection sample. However, this process can be time-consuming when utilizing intro-operative frozen section pathology. To address this issue, we propose utilizing confocal laser endomicroscopy to provide in situ, real-time, and in-vivo diagnosis of suspected peritoneal nodules as cancer metastasis during surgery.

Clinical Trial Description

Peritoneal metastasis is a common metastatic site in colorectal cancer patients, and those with peritoneal metastasis often have a poor prognosis. During surgery, peritoneal metastasis is confirmed pathologically through resection sample, but frozen section pathology can take up to 30 minutes, which is a significant amount of time. To address this issue, we suggest utilizing probed-based confocal laser endoscopy (pCLE), a novel endoscopic adjunct that enables real-time in vivo histological examination of mucosal surfaces. By using intravenous fluorescent agents, pCLE highlights certain mucosal elements that facilitate an optical biopsy in real time. By providing a promising optical biopsy, CLE has the potential to enable in situ, real-time, and in vivo diagnosis of colorectal cancer patients with peritoneal nodules during surgery. ;
