ObjectiveTo investigate the application of fast track surgery (FTS) in hepatobiliary surgery, and discuss the postoperative stress response and its efficacy and safety assessment. MethodsA total of 171 patients undergoing different hepatobiliary operations in our ward from August 2008 to Jule 2011 were randomly divided into control group (n=89) and FTS group (n=82). Patients in the FTS group received the improved methods while those in the control group received traditional care. A series of indicators such as hospital stay, hospital expense, duration of intravenous infusion, postoperative complications, and the C-reaction protein (CRP) and interleukin-6 (IL-6) levels in serum were observed postoperatively. ResultsFor the FTS and control group, the first exhaust time was respectively (2.4±0.3) and (3.3±0.6) days, postoperative hospital stay was (9.1±2.7) and (14.1±4.1) days, hospitalization expense was (16 432±3 012) and (21 612±1 724) yuan, all of which had significant differences (P<0.05). Before surgery and on the 1st, 3rd, 5th and 7th day after surgery, IL-6 serum level for the FTS group was respectively (8.57±2.58), (30.21±12.44), (17.41±11.73), (11.14±7.12), and (10.50±5.19) ng/L, and for the control group was respectively (9.13±2.99), (51.31±19.50), (36.82±12.33), (28.23±9.18), and (15.44±4.33) ng/L. There was no significant difference in the preoperative IL-6 level between the two groups (P>0.05), while IL-6 level was significantly lower in the FTS group than the control group after surgery (P<0.05). Before surgery and on the 1st, 3rd, 5th and 7th day after surgery, CRP serum level for the FTS group was respectively (18.41±4.01), (69.74±26.03), (45.52±20.50), (39.14±11.23), and (29.03±6.47) μg/L, and for the control group was respectively (17.74±2.11), (99.23±23.50), (86.81±17.34), (68.22±15.60), and (37.70±9.55) μg/L. There was no significant difference in the preoperative CRP level between the two groups (P>0.05), while CRP level was significantly lower in the FTS group than the control group after surgery (P<0.05). Postoperative complication rate after surgery was not significantly different between the two groups (P>0.05). ConclusionThe application of FTS in some hepatobiliary operations is effective and safe by decreasing the stress response.
ObjectiveTo observe the changes of peripheral blood lymphocyte subsets of patients with primary hepatocellular carcinoma (PHCC) treated with radiofrequency ablation (RFA). MethodsThe data of 70 cases of hospitalized patients with PHCC that voluntary accepted RFA diagnosed by clinical and pathological in our hospital between July 2011 and December 2014 were collected. According to the numbers of HCC lesions, 70 cases were divided into single focus group (n=41) and multifocal group (n=29). The changes of their immune parameters before and after RFA were analyzed. Results①The ratioes of peripheral blood CD3+/CD19-, CD3+/CD4+, CD4+/CD8+, and NK cells on 7 days and 14 days after RFA treatment of 70 cases were significantly higher than those on 1 day before RFA treatment (P < 0.05). The ratio of CD3+/CD8+ T cells reduced from 1 day before RFA treatment to 14 days after RFA treatment, but the difference was no statistically significant (P > 0.05).②The changing trend of peripheral blood lymphocyte subsets before and after RFA treatment in single focus group and multifocal group were similar to the above.③Compared with single focus group, the ratioes of peripheral blood CD3+/CD19-, CD3+/CD4+, CD4+/CD8+, and NK cells before and after RFA treatment in multifocal group were lower, and the ratio of CD3+/CD8+ T cells was higher, but the difference were not statistically significant (P > 0.05). ConclusionRFA can not only destroy small PHCC foci, but also to significantly improve immune function and enhance the anti-tumor effect.
