A Study of Intra-operative Imaging in Women With Ovarian Cancer

Overview

The purpose of this study is to find out whether using the PINPOINT imaging system intra-operatively can reduce the risk of anastomotic leaks and other complications after surgery for ovarian cancer, compared with standard intra-operative assessments alone. The PINPOINT endoscopic fluorescence imaging system uses a special camera and a fluorescent (glowing) dye that can evaluate the blood flow of the bowel in real-time. If there is an area that appears concerning, the surgeon can correct the problem during the procedure.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Diagnostic
    • Masking: None (Open Label)
  • Study Primary Completion Date: May 3, 2025

Interventions

  • Diagnostic Test: Intravenous Indocyanine Green/ICG injection
    • Intravenous Indocyanine Green/ICG injection will be administered for visualization
  • Diagnostic Test: PINPOINT endoscopic fluorescence imaging system
    • After resection the surgeon will use the PINPOINT imaging system to assess perfusion of the colonic stump. The intervention will again be used following establishment of the anastomosis, however this time via a proctoscope to visualize the proximal and distal ends of the rectosigmoid anastomosis.
  • Diagnostic Test: Endoscopy
    • Standard technique and assessment of anastomosis without the use of NIR angiography

Arms, Groups and Cohorts

  • Active Comparator: Arm A
    • Randomized to standard technique and assessment of anastomosis without the use of NIR angiography
  • Experimental: Arm B
    • Randomized to additional assessment of proximal colonic stump and anastomotic perfusion using NIR angiography

Clinical Trial Outcome Measures

Primary Measures

  • Reduction of the risk of 30-day postoperative anastomotic leak at the site of rectosigmoid resection, compared with standard intraoperative assessment alone
    • Time Frame: 45 days post procedure
    • To determine whether the use of NIR angiography assessment of perfusion at the time of rectosigmoid resection in a cohort of patients undergoing surgery for ovarian cancer reduces the risk of 30-day postoperative anastomotic leak at the site of rectosigmoid resection, compared with standard intraoperative assessment alone.
