NCT04641923

Brief Summary

There has been an increase in the need for repeat hepatic surgery, especially for patients with colorectal liver metastasis and hepatocellular carcinoma. Adhesions at the time of repeat surgery can lead to increased operative times, higher blood loss and even increased perioperative morbidity. Not much data exists regarding use of anti-adhesion barriers at the time of index hepatectomy and their effect on adhesions at repeat hepatectomy. This randomized controlled trial aims to evaluate the effectiveness of the use of a hyaluronan and cellulose based antiadhesive topical film at index hepatectomy in reducing perihepatic adhesions at the time of repeat hepatic surgery.

Masking Details
Once eligibility has been determined, participants will be randomized with a 1:1 ratio using a block randomization model. The randomization tool will be located on a password-protected website. In order to maintain allocation concealment, the assigned intervention (i.e. Seprafilm use) will be provided to the surgeon in an opaque, sealed envelope immediately before surgery by the research assistant. Patients and data analysts will be blinded to treatment allocation status.
Purpose

Intervention Model
PARALLEL
Model Details: The study population will consist of all consecutive adult patients undergoing a partial hepatectomy with a high likelihood of repeat hepatectomy. These will include patients with colorectal liver metastasis and those with hepatocellular carcinoma. All patients who consent to undergo a partial hepatectomy at the Foothills Medical Center and who meet the inclusion criteria will be contacted via phone prior to their surgery by a trial research assistant in order to obtain informed consent for enrolment in the trial. Patients will be randomized with a 1:1 ratio for seprafilm vs no seprafilm group.
