Methods The subjects were 82 patients with pN0 esophagea cancer who underwent Ivor-Lewis esophagectomy from January 2001 to January 2005. By using RT-PCR,VEGF C mRNA was detected in tumor issues,and Mucin (MUC1) mRNA was detected in lymph nodes. The Kaplan-Meier method was used to calculate the survival展开更多

Since traditional open esophageal cancer resection has the disadvantages of large trauma, long recovery period, and high postoperative complication rate, its clinical application is gradually reduced. The current report of minimally invasive Ivor-Lewis esophagectomy(MIILE) is increasing. However, researchers found that patients with MIILE had a higher incidence of early delayed gastric emptying(DGE).AIM To investigate the influencing factors of postoperative early DGE after MIILE.METHODS A total of 156 patients diagnosed with esophageal cancer at Deyang People's Hospital were enrolled. According to the criteria of DGE, patients were assigned to a DGE group(n = 49) and a control group(n = 107). The differences between the DGE group and the control group were compared. Multivariate logistic regression analysis was used to further determine the influencing factors of postoperative early DGE. The receiver operating characteristic(ROC) curve was used to assess potential factors in predicting postoperative early DGE.RESULTS Age, intraoperative blood loss, chest drainage time, portion of anxiety score ≥ 45 points, analgesia pump use, postoperative to enteral nutrition interval, and postoperative fluid volume in the DGE group were higher than those in the control group. Perioperative albumin level in the DGE group was lower than that in the control group(P < 0.05). Age, anxiety score, perioperative albumin level,and postoperative fluid volume were independent factors influencing postoperative early DGE, and the differences were statistically significant(P <0.05). The ROC curve analysis revealed that the area under the curve(AUC) foranxiety score was 0.720. The optimum cut-off value was 39, and the sensitivity and specificity were 80.37% and 65.31%, respectively. The AUC for postoperative fluid volume were 0.774. The optimal cut-off value was 1191.86 mL, and the sensitivity and specificity were 65.3% and 77.6%, respectively. The AUC for perioperative albumin level was 0.758. The optimum cut-off value was 26.75 g/L,and the sensitivity and specificity were 97.2% and 46.9%, respectively.CONCLUSION Advanced age, postoperative anxiety, perioperative albumin level, and postoperative fluid volume can increase the incidence of postoperative early DGE.展开更多

One group used a two-step method for creating a gastric tube,and the other group used the conventional method. The two groups were compared regarding the operating time,surgical complications,and number of stapler cartridges used.RESULTS The mean operating time was significantly shorter in the two-step method group than in the conventional method group [238(179-293) min vs 272(189-347) min,P < 0.01]. No postoperative death occurred in either group. There was no significant difference in the rate of complications [14(21.9%) vs 13(22.4%),P= 0.55] or mean number of stapler cartridges used [5(4-6) vs 5.2(5-6),P = 0.007] between the two groups.CONCLUSION The two-step method for creating a gastric tube during laparoscopic-thoracoscopic Ivor-Lewis esophagectomy has the advantages of simple operation,minimal damage to the tubular stomach,and reduced use of stapler cartridges.展开更多
