RESUMO
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.
RESUMO
Objective To explore the diagnosis and surgical treatment of pulmonary sequestration.Methods 12 patients of pulmonary sequestration were retrospectively studied.Results Between January 2002 and December 2005 12 patients with pulmonary sequestration were operated in our department.8 patients were diagnosed preoperatively by chest enhanced CT which showed an abnormal feeding artery.4 patients were misdiagnosed.10 cases of intralobar were performed lobectomy,2 cases of extralobar were resected the separated lung tissue.No death occurred in our group.Conclusion Enhanced CT scan is a major diagnostic method of pulmonary sequestration and operation can obtain excellent results.
RESUMO
Objective To develop a whole-automatic intellectual thermochemotherapy equipment of peritoneal perfusion by which hyperthemic chemotherapeutics were post in peritoneal cavity with constant flow pump.Methods MSP430 one chip whole-automatic machine was adopted to monitor and keep chemotherapeutic temperature.Results Being treated with peritoneal perfusion thermochemotherapy after radical excision,one-year and three years survival rates of the patients with advanced gastric carcinoma were increased 8.12% and 20%,meso-life span extends 18 months.Conclusion The thermochemotherapy equipment of peritoneal perfusion can eliminate dissociating malignant cell in peritoneal cavity and minimum cancer focus on peritoneal membrane,and prevent peritoneal recurrence effectually.
