Abstract:
Objective To investigate the effects of peri-operative enteral nutrition (EN) and antibiotics on intestinal flora balance in patients with esophageal carcinoma.Methods Sixty patients were randomly divided into six groups:Group B,treated with antibiotics for 3 days and supported with EN before and after operation; Group C,treated with antibiotics for 3 days and supported with parenteral nutrition (PN) before operation and EN after operation ; Group D,treated with antibiotics for 3 days and supported with PN before and after operation ; Group E,treated with antibiotics for 7 days and supported with EN before and after operation; Group F,treated with antibiotics for 7 days and supported with PN before operation and EN after operation ; and Group G,treated with antibiotics for 7 days and supported with PN before and after operation.The first stool after surgery was obtained and tested for Bacteroides,Bifidobacterium,Lactobacillus,Escherichia coli,and Enterococcus.Ten healthy adults were enrolled as the blank control group.The numbers of the flora and ratio of Bifidobacteria to Enterococci (B/E) were compared.Complications such as incision infections,lung infections,and anastomotic fistula were recorded.Results The numbers of Bifidobacterium [(10.59 ± 0.39) vs.(10.88 ± 0.10) lg10n/ml,P =0.186),Lactobacillus [(8.59±0.31) vs.(8.72 ±0.22) lg10n/ml,P=0.534],Escherichia coli [(8.43 ±0.50) vs.(8.67 ±0.24) lg10n/ml,P=0.266],Enterococcus [(7.40 ±0.61) vs.(7.78 ±0.16) lg10n/ml,P =0.111],and B/E value [(1.2589 ± 0.0644) vs.(1.2560 ± 0.0330),P =0.825] in the Group B were not significantly different from the blank control group.The numbers of Bacteroids [(11.08 ± 0.48),P =0.139 ; (9.23 ± 0.42),P =0.000; (10.80±0.26),P=0.004; (10.24±0.45),P=0.000; (8.05±0.53),P=0.000vs.(11.36±0.48) lg10n/ml],Bifidobacterium [(10.19 ±0.49),P=0.062; (9.00 ±0.52),P=0.000; (9.31 ±0.45),P=0.000; (8.47±0.56),P=0.000; (6.99 ±0.56),P =0.000 vs.(10.59±0.39) lg10n/ml],Lactobacillus [(7.99 ± 0.58),P =0.006 ; (6.84 ± 0.47),P =0.000 ; (7.72 ± 0.35),P =0.000 ; (6.93 ±0.43),P =0.000; (5.93 ±0.76),P=0.000 vs.(8.59 ±0.31) lg10n/ml],Escherichia coli [(8.19 ±0.43),P=0.258; (7.93±0.60),P=0.020; (7.47±0.43),P=0.000; (6.90±0.42),P=0.000; (6.58±0.57),P =0.000 vs.(8.43 ± 0.50) lg10n/ml],and Enterococcus [(6.90 ± 0.54),P =0.037 ; (5.89 ± 0.68),P =0.000; (6.20±0.52),P=0.000; (5.91 ±0.39),P=0.000; (5.14±0.58),P=0.000 vs.(7.40±0.61) lg10n/ml] of groups C,D,E,F,and G decreased compared with those of the Group B.The values of B/Ein the D and G groups decreased significantly when compared to the blank control group (1.1433 ±0.1350,P =0.025 ; 1.0706 ± 0.1413,P =0.000 vs.1.2560 ± 0.0330).The incidences of pulmonary infections (x2 =3.647,P =0.601) and anastomotic leak (x2 =5.000,P =0.416) among all groups were not significantly different.Conclusions EN applied 3 days before surgery and after surgery is beneficial for maintaining the balance of intestinal flora.Long-term administration of antibiotics may cause dysbacteriosis and even increase complications.
