腹腔镜胃癌根治术后营养支持的临床疗效

目的 探讨肠内营养与肠外营养对腹腔镜胃癌根治术后营养不良患者的临床疗效.方法 通过前瞻性对照研究分析2007年12月至2010年4月在中山大学附属第三医院行腹腔镜胃癌根治术60例患者营养支持的临床资料,按随机数字表法分为肠内营养组和肠外营养组(每组各30例),比较营养支持后两组患者的人体测量学,营养学指标,营养相关并发症及费用.计量资料采用t检验,计数资料采用x2检验.结果 肠内营养组患者体质指数、三头肌皮褶厚度、上臂肌围、Hb、转铁蛋白、Alb分别为(16.9±2.4)kg/m2、(10.6±2.5)mm、(24.2±2.5)cm、(106±15)g/L、(2.2+0.4)g/L、(39±3)g/L,肠外营养组患者分别为(16.6±2.1)kg/m2、(9.2±1.3)mm、(24.0±3.4)cm、(102±18)g/L、(2.0+0.4)g/L、(38±3)g/L,两组比较差异均无统计学意义(t=0.52,1.72,0.05,0.93,1.94,1.29,P＞0.05).但肠内营养组前白蛋白、氮平衡水平、肛门排气时间、每日相关费用、菌群失调、糖代谢紊乱、肝功能损害分别为(0.30±0.10)g/L、0.8±0.3、(29±10)h、(210±30)元、1例、2例、2例,肠外营养组分别为(0.25±0.09)g/L、0.4±0.2、(38±6)h、(700±50)元、9例、12例、15例,两组比较差异有统计学意义(t=2.03,6.08,2.25,10.38,x2=7.68,9.32,13.87,P<0.05).结论 腹腔镜胃癌根治术后对患者实施营养支持可促进患者的恢复,而肠内营养疗效优于肠外营养,可作为营养支持的首选途径.

Enteral and parenteral nutritional support for gastric cancer patients undergoing laparoscopic radical gastrectomy

Objective To compare the effect and safety of enteral and parenteral nutritional support for gastric cancer patients undergoing laparoscopic radical gastrectomy(LRG). Methods Sixty gastric cancer patients received nutritional support after LRG at The Third Affiliated Hospital of Sun Yat-sen University from December 2007 to April 2010. All patients were randomly divided into the enteral nutrition(EN) group (n = 30)and parenteral nutrition (PN) group (n = 30) according to the random number table. Anthropometry, nutritional indexes, complications and expenses of the two groups were compared after treatment. All data were analysed by using the t test and chi-square test. Results Body mass index, triceps skin fold, mid-upper arm muscle circumference, hemoglobin levels, transferrin levels, and albumin levels were ( 16.9 ± 2.4) kg/m2, ( 10.6 ± 2.5 ) mm,(24.2 ±2.5) cm, (106 ± 15) g/L, (2.2 ±0.4) g/L and (39 ±3) g/Lin the EN group, and they were (16.6 ±2.1) kg/m2, (9.2 ± 1.3) mm, (24.0 ±3.4) cm, (102 ± 18) g/L, (2.0 ±0.4) g/L and (38 ±3) g/L in the PN group, respectively, with no significant differences between the two groups (t =0. 52, 1.72, 0.05, 0.93, 1.94,1.29, P ＞ 0.05). Prealbumin levels, nitrogen balance, time of first flatus, and daily expenses in the EN group were (0.30 ±0.10) g/L,0.8 ±0.3, (29 ± 10) hours and (210 ±30) yuan, while they were (0.25 ±0.09) g/L,0. 4 ± 0.2, (38±6) hours and ( 700 ± 50) yuan in the PN group, respectively, with a significant difference between the two groups ( t = 2. 03, 6. 08, 2. 25, 10. 38, P ＜ 0.05 ). One patient had dysbacteriosis, two were glycometabolic and two had a hepatic disorder in the EN group, while the corresponding numbers in the PN group were 9, 12 and 15 patients, respectively, with a significant difference between the two groups ( x2 =7.68, 9.32,13.87, P ＜ 0.05). Conclusions Nutritional support can promote the recovery of gastric cancer patients undergoing LRG. The efficacy of EN is superior to that of PN, and EN is the method of choice for nutritional support.
