Objective To explore the protective effect of early enteral nutrition on intestinal mucosa barrier in patients with esophageal carcinoma after operation. Methods Fifty six patients with esophageal carcinoma whose weight decreased more than 20% before operation in three months were divided into enteral nutrition group ( n =30) and parenteral nutrition group ( n =26). Plasma concentration of lipopolysaccharide(LPS), tumor necrosis factor (TNF), gastrin, glutamine, and ratio of lactulose and mannitol (L/M) were measured on the 1st, 4th, 8th day after operation respectively. Results Weight loss and infectious complication in enteral nutrition group were less than those in parenteral nutrition group after operation ( P lt;0.01, 0.05). On the 4th and 8th day after operation,the level of LPS,TNF, and L/M were lower in enteral nutrition group than those in parenteral nutrition group ( P lt;0 01), the values of gastrin and glutamine were higher in enteral nutrition group than those in parente...更多ral nutrition group ( P lt;0 01). Conclusion Enteral nutrition can protect the intestinal mucosa barrier and decrease infectious complication after operation.
Mini-invasive video-assisted thoracoscopic surgery (VATS) has been employed in diagnosis and treatment of esophageal diseases for about 10 years. The potential advantages of VATS over thoracotomy are reduction of chest pain just after the operation and in the long run, lower incidence of postoperative respiratory complications, and reduction of aesthetic sequelae. Thoracoscopic staging of esophageal cancer is to evaluate the invasion and metastasis of cancer, which is helpful for better selection of patients for appropriate treatment .Operation of esophageal cancer with VATS is prescribed mainly in the early stage of carcinoma, but it’s application is restricted due to the multiple sites of operation and complexity of procedures. VATS for benign esophageal diseases such as esophageal leiomyoma and achalasia is becoming the preferable choice of operation in qualified medical centers.
Objective To summarize the clinical application of esophagogastrostomy with layered anastomosis and to observe the healing quality of anastomotic stoma in animal experiments. Methods One thousand and twenty-four patients suffered from carcinoma of esophagus or carcinoma of gastric cardia had undergone esophagogastrostomy by layered anastomosis with absorbable suture. Twenty-four experimental dogs (adult male healthy hybrid dogs) were divided into two groups: the experimental group and the control group. The former (experimental group) underwent the layered anastomosis, the diameter of esophagogastric stoma and the length and depth of stomal scar were measured under anesthesia in both groups on 5th,8th,14th,and 42th postoperative day, respectively. So were done the histological measurement, such as the count infiltrating inflammatory cells, the proliferation of blood capillary and other cells. And the cytokines related to wound healing (LsAB technique) such as epidermal growth factor(EGF), transforming growth factor-beta 1 (TGF-beta 1) were detected, either. Results One thousand and twenty-four patients had no anastomotic leakage. There were only 6 patients suffered from mild anastomotic stricture, and they got well after one dilatation. The results of the measurement of 24 experimental dogs revealed that, in the experimental group, the mucosa was in good connecting condition, had a soften anastomotic stoma and a thin scar. The counts of inflammatory cells and fibroblast showed more in number at the early time after operation (Plt;0.05), while showed less in number at the advanced time of operation (Plt;0.05). In the control group, however, the mucosa were in a bad connecting condition, the scar was thicker, and the muscle layer was frequently exposed. The counts of inflammatory cells and fibroblast were fewer at the early time after operation, however, they had a clearly tendency of increasing at the anaphase after the operation. On the cytokines related to the healing of wound in the experimental group, there was a high expression and activity at the early period. There were a little expression up to postoperative 42 d. Whereas, in the control group, there had a low expression level,increased clearly on postoperative 8 d, and still a higher expression up to postoperative 42 d. Conclusions The esophagogastrostomy by layered anastomosis has a high healing quality with a thin scar. The proliferation of cells and the expression of growth factors benefits the normal healing of wound by first intention.
