COLOFLOW: Laser Speckle Contrast Imaging Versus Near-infrared Fluorescence Imaging With Indocyanine Green

COLOFLOW is a prospective observational study investigating whether Laser Speckle Contrast Imaging (LSCI), a dye-free and objective perfusion imaging technique, corresponds with the currently used subjective assessment of indocyanine green (ICG) fluorescence during colorectal surgery. In approximately 30 patients undergoing elective colon or rectal resection with primary anastomosis, both imaging modalities will be performed intraoperatively. The surgeons will base their clinical decisions solely on standard ICG fluorescence imaging, while LSCI measurements are collected for research purposes and do not influence treatment. Postoperatively, quantitative ICG parameters will be analysed and compared with LSCI perfusion maps to determine whether objective ICG analysis improves agreement with LSCI over subjective interpretation alone. In addition, the study will evaluate the feasibility of using the PerfusiX-IGS LSCI system during open colorectal surgery and describe postoperative outcomes, including anastomotic leakage. The ultimate goal is to contribute to more objective and standardized perfusion assessment during colorectal surgery

Post Operative Hospital at Home After Colorectal Surgery

The goal of this feasibility study is to investigate whether a virtual Hospital at Home is safe and possible for patients undergoing planned minimally invasive colorectal surgery. The study aims to answer the following main questions: What are the patient- and next-of-kin-related effects, as well as the clinical and organizational effects, of home-based admission? What are the implementation barriers for a full-scale randomized controlled trial? Participants will follow a standardized protocol for their care befor, during and after surgery. However, the care after surgery will be conducted at home using telemedicine.
