Liver regeneration after atypical hepatectomy in the rat. A comparison of CO2 laser with scalpel and electrical diathermy.
Rats were subjected to partial hepatic lobectomy with removal of about two thirds of the liver either by scalpel, by CO2 laser, or by electrical diathermy. Macroscopic examinations of livers at various days after surgery indicated that CO2 laser surgery results in minor tissue damage, reduced complications from inflammation and infections, and faster healing compared to electrical diathermy, but it is less satisfactory than the scalpel with respect to all these parameters. Rat liver regeneration was followed at the molecular level by measuring the changes of protein biosynthesis activity in the liver, as monitored by modifications of ribosome organization. Activation of the protein biosynthesis process started 1 day after surgery when hepatectomy was performed by scalpel, while 2 days were required when CO2 laser or electrical diathermy were used instead.
