目的:总结食管胸段癌Ivor Lewis食管切除术后胃延迟排空的防治对策。方法:回顾性分析我院3100例食管胸中下段癌行Ivor Lewis食管切除术后胃延迟排空的发生率。根据术中采取不同措施分为:A组(裂孔切开)和B组(不作裂孔切开),P组(幽门括约肌捏断)和N组(不作幽门处理),管胃组(管胃替代食管)和全胃组(全胃代食管),PM组(幽门括约肌捏断) 、PN组(不作幽门处理)和PP组(幽门成形)。比较不同处理方式前后胃延迟排空的发生率。结果:Ivor Lewis食管切除术后胃延迟排空的总的发生率为13.8%(427/3100)。术中裂孔扩大后胃延迟排空的发生率从32%(A组)降至21%(B组)(Plt;0.05);术中同时行幽门括约肌捏断后胃延迟排空的发生率从21%(N组)降至9%(P组)(Plt;0.05);采用管胃替代食管后胃延迟排空的发生率从19.5%(全胃组)降至8.3%(管胃组)(Plt;0.05);管胃组中PN组胃延迟排空的发生率为15%,PP组为8%,行幽门成形(PP组)后降至2% (Plt;0.05)。结论:胃延迟排空是Ivor Lewis食管切除术后主要的并发症,术中扩大食管裂孔、管胃替代食管和幽门成形可有效防治术后胃延迟排空的发生。
Objective To observe the expression of Twist in esophageal squamous cell carcinoma (ESCC) and analyze the relationship between positive expression of Twist and disease-free survival, and to provide clinical evidence for reducing tumor recurrence, prolonging disease-free survival and improving prognosis. Methods Retrospective analysis of 70 ESCC patients receiving thoracic surgery from June 2010 to June 2012 in the Department of Thoracic Surgery, Sichuan Cancer Hospital was done, including 39 males and 31 females with an average age of 63.6 years. The expression of Twist in normal esophageal tissue, tumor tissue and vascular tumor emboli was observed by immunohistochemical staining of paraffin specimens. Results The positive rate of Twist in normal esophageal tissues was 42.9%, and in tumor tissue was 77.1% (P<0.05). The positive expression rate of Twist in tumor cells was 74.3% in patients with vascular tumor emboli and 80.0% in patients without vascular tumor emboli (P>0.05). The positive expression rate of Twist in tumor cells and in vascular tumor emboli was 74.3% and 71.4%, respectively (P>0.05). The expression of Twist in lymphatic vessels and blood vessels of patients with vascular tumor emboli was 56.0% and 72.0%, respectively (P>0.05). Conclusion Twist expression in esophageal cancer tissues is significantly higher than that in normal tissues, but there is no significant difference in the positive expression of Twist between tumor cells and the mean disease-free survival (P>0.05). At present, Twist expression can not be used as a prognostic indicator of esophageal cancer, and more researches need be further implemented.
Objective To analyze the Podoplanin expression in patients with esophageal squamous cell carcinoma and to find out the relationship between Podoplanin expression and tumor embolus, lymph node metastasis, tumor differentiation as well as prognosis, and to provide clinical evidence for reducing the recurrence of esophageal squamous cell carcinoma and prolonging the disease-free survival and overall survival. Methods A retrospective analysis of 70 patients with esophageal squamous cell carcinoma in our hospital from June 2010 to June 2012 was conducted, including 39 males and 31 females, with a mean age of 63.6 years. Positive diagnosis of tumor thrombus was achieved in 35 patients and negative in 35 patients. Postoperative pathological specimens were examined and normal esophageal tissues (esophageal tissue more than 5 cm from the edge of the tumor) of patients were excised as a control group. Results The positive rate of Podoplanin was 34.2% in normal esophageal tissues and 62.8% in tumor tissues. The positive rate of Podoplanin expression was 77.1% and 48.6% in esophageal squamous cell carcinoma patients with or without tumor embolus, respectively. The positive rate of Podoplanin expression in tumor cells of patients with positive and negative lymph node metastasis was 71.9% and 23.1%, respectively (P<0.05). The mean disease-free survival of patients with Podoplanin expression-negative esophageal squamous cell carcinoma was 15.2 months, which was significantly longer than that of patients with Podoplanin expression-positive esophageal squamous cell carcinoma (P<0.05). Conclusion Podoplanin expression in the tumor cells and vessels can be an important reference index to the prognosis of patients with esophageal squamous cell carcinoma.
