ABSTRACT
Objective To study the effect of early enteral nutrition (EEN) with ω-3 polyunsaturated fatty acid on nutritional status and body immunity of postoperative patients with colorectal cancer.Methods Forty patients with colorectal cancer were randomly divided into EEN group and parenteral nutrition (PN) group by systematic sampling method with 20 cases of each.The patients in EEN group were given complete enteral nutrition with ω-3 polyunsaturated fatty acid 1-7 d after operation,while the patients in PN group only were given nutrient by regular PN.Nutritional status,body immunity before operation and 1-7 d after operation,and intestinal function recovery time,untoward reaction were determined.Results The postoperative anus first exhaust time and defecate time of patients in EEN group were significantly shorter than those in PN group [(48.0±5.6) hvs.(51.0±6.7) h,(53.0±4.8) h vs.(72.0±3.6) h,P＜0.05].Serum albumin and prealbumin 1 d after operation in 2 groups were significantly lower than before operation (P ＜0.05),but 7 d after operation were significantly higher than 1 d after operation (P ＜0.05).Serum albumin and prealbumin 7 d after operation in EEN group were significantly higher than PN group(P ＜ 0.05).IgG,IgA,IgM,CD3,CD4,CD8,CD4/CD8 1 d after operation in 2 groups were significantly lower than before operation (P ＜ 0.05).IgG,IgA,CD4,CD4/CD8 7 d after operation in EEN group were significantly higher than PN group (P＜ 0.05).Conclusions Compared with the PN,EEN with ω-3 polyunsaturated fatty acid can remarkably improve nutritional status and body immunity in postoperative patients with colorectal cancer.It can accelerate the recovery of intestine function and worthy of recommending.
ABSTRACT
Objective To investigate the value of LigaSure vessel sealing system for surgery in gastroenteric cancer. Methods From January to September 2009,44 cases of gastroenteric cancer were operated by using LigaSure vessel sealing system,including 13 cases of gastric cancer, 14 cases of colon cancer, 17 cases of rectum cancer. Laparoscopy was employed in 10 cases. Results All the cases were performed successfully. The operation time was 130-250 min, the blood loss was 50-250 ml, and the number of lymph nodes resected was 4-20. None of the cases had serious complications. Conclusion As an optimal hemostatic tool, LigaSure vessel sealing system is safe and feasible for gastroenteric cancer.
ABSTRACT
Objective To evaluate the feasibility of Selective Portal Vein Embolization(SPVE)in rabbits with the mixture of ZT glue and Lipiodol.Methods Sixteen white New Zealand rabbits were randomly divided into 2 groups:Group A,ZT glue:Lipiodol(1:2)mixture and Group B Lipiodol group.SPVE of left branch was performed in each group under digital subtraction angiography.The distribution feature of the embolic agents and the histopathology of liver in each group were observed.The weight ratio of the right lobe to the whole liver at the 30th day after SPVE were recorded and analyzed.Results Permanent embolization were occurred in group A.Recanalization was appeared in group B.Atrophy of the embolized lobes and compensatory hypertrophy of none-embolized lohes was,observed..The weight ratio of the right lobe to the whole liver Was 69.41±5.10% in group A.There was statistical difference between these two groups(P＜0.05).Conclusion There were permanent embolization after SPVE with the mixture of ZT glue and lipiodol.SPVE induced atrophy of the embolized lobes of liver and compensatory hypertrophy of none-embolized lobes.
