The role of prostaglandins in hepatic resection.

The role of prostaglandins (PGs) and the efficacy of PGE1 were investigated in hepatic resection. Patients who underwent hepatic resection were randomly assigned to two groups consisting of a control (n = 5) and a PGE1 treatment group (n = 6). Then the amount of 6-keto PF1 alpha, thromboxane B2 and (TXB2) and PGE2 were serially measured both before and after hepatic resection. Regarding changes in the PGs, a remarkable increase in TXB2 during hepatectomy was demonstrated in both groups. In the control group, both 6-keto PF1 alpha and PGE2 showed only a slight increase both during and after the operation. Regarding the efficacy of PGE1 on liver damage, no significant difference in postoperative liver function was found, however the lipoperoxide level at postoperative day 3 in the PGE1 treatment group (1.9 +/- 0.4 nmol/ml) was significantly lower than that in the control (2.6 +/- 0.5 nmol/ml: P < 0.05). Judging from the remarkable increase of TXB2, a stable metabolite of TXA2 during hepatectomy, it may be suggested that TXA2 plays an important role in the development of liver damage during hepatic resection.
