Experimental Study on Left-sided Hepatectomy in Pigs
Author Information

Primary Institution: Lund University Hospital, Sweden
Hypothesis
Does the use of Surgicel(R) reinforce resection lines during left-sided hepatectomy improve outcomes compared to stapling alone?
Conclusion
The use of Surgicel(R) did not significantly improve outcomes and was associated with a higher frequency of adhesions.
Supporting Evidence
- The median time for resection was shorter in the Surgicel(R) group, but not statistically significant.
- The postoperative hemoglobin value was significantly higher in the Surgicel(R) group compared to the stapled group.
- Four out of six pigs in the Surgicel(R) group had massive adhesions to the resection lines.
Takeaway
The study tested a new way to help stop bleeding during liver surgery in pigs, but it didn't work as well as hoped and caused some problems.
Methodology
Fourteen pigs underwent left-sided hepatectomy with either a linear stapling device alone or with Surgicel(R) reinforcement, and various outcomes were measured postoperatively.
Potential Biases
Potential bias due to the small sample size and the nature of animal studies.
Limitations
The study was conducted on a small number of pigs, which may limit the generalizability of the results.
Participant Demographics
Swedish domestic pigs of random sex, median body weight around 20 kg.
