RESUMO
Objective To evaluate the value of intermittent splenic artery occlusion in the treatment of iatrogenic splenic injury and the cause of ischemia reperfusion injury.Methods Experimental animals using dogs were divided into experimental group and control group according to whether the splenic artery was blocked.The animal model of iatrogenic splenic injury was established by general anesthesia.Experimental group was treated with intermittent splenic artery blockage combined with gelatin sponge oppression of the wound to stop bleeding.The first time of splenic artery occlusion was 15 min and continued for 10 min and for another 5 rmin if still bleeding.Then hemostatic effect after removing blocking and oppression was observed.Control group was only treated with gelatin sponge compression to stop bleeding.Blood samples and tissue samples were collected before blocking and after reperfusion for 2 hours in experimental group,and before compression and relieving the compression for 2 hours in control group.IL-1 (interleukin),SOD (superoxide disproportionation enzyme),MPO (myeloperoxidase),MDA (malondialdehyde) and caspase-3 (aspartame acid cysteine protease) were detected.Results The control group still had bleeding,while the experimental group had successfully stopped bleeding.Serum markers before and after occlusion in the experinental group were IL-1 (124.4 ± 106.8 vs.121.2 ± 105.1),SOD (4.7 ± 2.7 vs.5.2 ± 1.8) and MDA (8.8 ±6.5 vs10.8 ±7.5).There were no significant differences on serum markers in two groups after occlusion/oppression including IL-1 (121.2 ± 105.1 vs.162.8 ± 73.8),SOD (5.2 ± 1.8 vs.4.7 ± 2.8) and MDA (10.8 ±7.5 vs.9.6 ±6.6) (P＞0.05).Histological indicators before and after occlusion in the experimental group included MPO (0.62 ±0.23 vs.0.68 ±0.21) and Caspase-3 (0.90 ±0.29 vs.0.86 ± 0.26),and there was no statistical difference on MPO (0.68 ±0.21 vs.0.86 ±0.23 after two sets of experiments) and Caspase-3 level (0.86 ± 0.26 vs.1.21 ± 0.18) (P ＞ 0.05) in two groups after occlusion/ oppression.Conclusion The therapeutic effect of intermittent splenic artery occlusion combined with gelatin sponge compression hemostasis is safe and effective and without obvious ischemia reperfusion injury.
RESUMO
Objective:To investigate the effect of early enteral nutrition combined with Bacillus in the treatment of patients with digestive tract perforation.Methods:59 patients with emergency digestive tract perforation were randomly divided into experimental group (EN plus Bacillus,n =31) and control group (TPN,n =28).The patients in the experimental group were given enteral nutrition plus Bacillus after first days (＜ 24 h),and the control group was treated with parenteral nutrition support on the first day after surgery.The average hospitalization time,length of ICU stay,incidence of complications,and serum C-reactive protein in the two groups were analyzed.Results:The average length of hospitalization time,ICU stay,recovery of bowel function and eating time were significantly shorter in the experimental group than in the control group(P ＜ 0.05).There was no significant difference in nutrition index between the two groups during the perioperative period (P ＞ 0.05).The C-reactive protein in the experimental group was significantly lower than that in the control group fourth days after operation (P ＜ 0.05).The incidence of postoperative wound infection in the experimental group was significantly lower than that of the control group (P ＜ 0.05).There was no significant difference in the incidence of other complications.Conclusion:Early administration of enteral nutrition combined with Bacillus can significantly shorten the intestinal function recovery time,decreasethe average hospitalization days,reduce the postoperative wound infection rate and thus improve the outcome of patients with digestive tract perforation.
RESUMO
Objective To evaluate the clinical value of a novel anvil insertion technique in intracorporeal esophagojejunostomy and esophagogastrostomy after laparoscopic total or proximal gastrectomy.Methods A total of 40 patients with gastric cancer underwent laparoscopy-assisted radical total or proximal gastrectomy with lymph node dissection,followed by esophagojejunostomy or esophagogastrostomy using a reverse anvil insertion technique (the observation group,n =22) or traditional open surgery technique (the control group,n =18).Data of the two groups were compared.Results In observation group,laparoscopic total gastrectomy and esophagojejunostomy were successfully performed in 17 patients,laparoscopic proximal gastrectomy and esophagogastrostomy were successfully performed in the 5 patients,and no conversion to open surgery occurred.The mean time of operation was (272.0 ±49.8)min,including (12.9 ±4.3)min for anvil insertion and (48.1 ± 12.8)min for digestive tract reconstruction,which were significantly shorter than those in control group (P ＜ 0.05).The mean time of getting out of bed in observation group was (3.4 ± 0.8) d,the mean time of post-surgical eating was (8.0 ± 2.6) d,and the mean time of hospitalization was (10.8 ±3.3)d,which were all similar with those from the control group (P ＞0.05).Conclusion The reverse anvil insertion technique is a reliable strategy for laparoscopic esophagojejunostomy or esophagogastrostomy.
