RESUMO
Objective:To evaluate the safety and feasibility of enhanced recovery after surgery (ERAS) in the Radical Distal Gastrectomy.Methods:The clinical data of 52 patients who underwent radica distal gastrectomy surgery from Jan 2016 to Jan 2017 were collected,and divided into the ERAS group and the control group.Results:(1) Operation condition:the operative time,volume of intraoperative blood loss,number of patients with conversion to open surgery showed no statistically significant difference between the 2 groups (P＞0.05).(2)postoperative clinical indexes:time for initial anus exhaust,time for initial liquid diet intake,time for out-of-bed activity,time of urinary catheter removal,duration of hospital stay of patients without complications days in the ERAS group and days in the control group,respectively,have been with statistically significant differences between the 2 groups(P＜0.05).But the time to initial defecation,time of abdominal drainage-tube removal and the number of postoperative complications during hospitalization between the 2 group had no statistically difference(P＞0.05).(3)Postoperative complications:at the first days and the third days after operation,WBC,CRP and IL-6 in ERAS group were lower than thoese in the control group,the differences were statistically significant.Conclusion:The perioperative ERAS program in distal gastrectomy is safe and effective and should be popularized.
RESUMO
Objective:To evaluate the safety and feasibility of enhanced recovery after surgery (ERAS) in total laparoscopic Uncut Roux-en-Y gastrojejunostomy after distal gastrectomy.Methods:The clinical data of 42 patients who were divided into ERAS group (n=20) and control group (n=22) were collected.Observation indicators included operation condition,postoperative clinical indexes and postoperative serum stress indexes.Measurement data with normal distribution were presented as-x±s and analyzed by T test.Count data were analyzed by the chi-square test.Results:The operative time,volume of intraoperative blood loss and number of patients with conversion to open surgery shown no statistically significant difference between the 2 groups(P＞0.05).Postoperative clinical indexes:time for initial anus exhaust,time for initial liquid diet intake,time for out-of-bed activity,duration of hoSpital stay of patients without complications in the ERAS group were lower than in the control group,with statistically significant differences between the 2 groups (P＜0.05).But the time to initial defecation,time of abdominal drainage-tube removal and the early postoperative complications between the 2 group had no statistically difference(P＞0.05). Postoperative complications:at the first days and the third days after operation,WBC,CRP and I L-6 in ERAS group were lower than in the control group,the differences were statistically significant (P＜0.05).Conclusion:The perioperative ERAS program in total laparoscopic Uncut Roux-en-Y gastrojejunostomy after distal gastrectomy is safe and effective and should be popularized,meanwhile,it can also reduce duration of hospital stay and improve the comfortable degree and satisfaction of patients.
RESUMO
<p><b>OBJECTIVE</b>To investigate the effect of chemokine stromal cell-derived factor-1 (SDF-1) and its receptor CXCR4 on liver metastasis of human colon cancer.</p><p><b>METHODS</b>Expression of CXCR4 in different colon cancer cell lines and SDF-1 in different tissues were detected by using Western-blot technique. Effect of SDF-1 and anti-CXCR4 monoclonal antibody (McAb) on proliferation and migration of HT-29 cells were measured using MTT methods. Model mimicking liver metastasis of human colon cancer was established by injecting HT-29 cells intrasplenically into BALB/C nude mice. Mice were randomly divided into AMD3100 treated group and control group. Liver metastatic rate and tumor foci were measured 7 weeks after.</p><p><b>RESULTS</b>HT-29 cells expressed higher level of CXCR4 protein, and liver tissue expressed higher level of SDF-1 protein. Compared with the control, SDF-1 could significantly induced the proliferation and migration of the HT-29 cells, and anti-CXCR4 McAb could inhibited both functions of SDF-1. The liver metastasis rate in the control group was 100%, and it was 40% in the AMD3100 treating group (P < 0.05). The mean liver metastasis number also significantly decreased by AMD3100 (7.8 +/- 2.6 vs 22.4 +/- 8.6, P < 0.05).</p><p><b>CONCLUSIONS</b>SDF-1/CXCR4 biological axis play an important role in liver metastasis of human colon cancer. Arrest of CXCR4 can inhibit liver metastasis of colon cancer through blocking cell proliferation and migration induced by SDF-1.</p>
