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.

Outcome Measures
Primary Outcomes (1)
Incidence of peri-hepatic adhesions at the time of repeat liver surgery
Evaluation will be performed at second surgery as follows: Calgary Scoring System Grade1-No adhesions, Grade2-Mild, Grade3-Moderate, Grade4-Severe adhesions, Grade5-severe adhesions with injury to other organs TORanomon Adhesion score (TORAD score): * Hepatic Hilum * 1-Easy: Easy for encircling the hepatoduodenal ligament (HDL) * 2-Hard: Additional maneuver for encircling HDL * 3-Extreme: Safe encircling of HDL is impossible * Liver Surface * 1-Easy: No adhesion * 2-Hard: Presence of dense fibrosis or scarring tissue- hard dissection * 3-Extreme): Dense scar with unclear boundary with the surrounding organs.
0-4 years from initial surgery, time of repeat surgery will vary from patient to patient

Eligibility Criteria
You may qualify if:
- Patients undergoing partial hepatectomy with high likelihood of needing repeat hepatectomy (e.g. those with colorectal liver metastasis and hepatocellular carcinoma)
- Patients ≥ 18 years of age.
You may not qualify if:
- Patients unable to provide informed consent.
- Patients with hypersensitivity to Seprafilm and/or to any components of the Seprafilm.
- Patients who are found to have unresectable disease during surgery (additional hepatic lesions or extrahepatic metastatic disease precluding liver resection

- 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.
