Objective To study the diagnosis and surgical treatment of multi-primary esophageal carcinoma. Methods The data of 29 patients of multi-primary esophageal carcinoma were collected .The diagnosis was made by dye-staining through gastroscopy and X-ray examination.Pathological examination after operation was analyzed.Three kinds of operations were used: 22 by radical resection, 5 by partial resection and 2 by surgical exploration. Results Twenty-one patients were diagnosed before operation,8 patients were diagnosed during and after operation. Sixty-seven foci and 6 early stage patients were found. The complications were found in 7 patients.No patient died during operation. Twenty-five patients were followed up. The follow up time was 7-36 months.1-year survival rate 77.8%,3-year survival rate 41.6%. Conclusion Routine X-ray examination of esophagus, and esophageal dye-staining and/or biopsy through endoscopy are important measures for early diagnosis of multi-primary esophageal carcinoma.Prompt surgery is advised.
Objective To explore the expression of CD105 protein in esophageal squamous cell carcinoma and it's relationship with P53 protein. Methods Using streptavidin biotinperoxidase (SP) method, the expression of CD105 protein and P53 protein in esophageal squamous cell carcinoma were examined in normal esophageal tissues (n=10) and esophageal squamous cell carcinoma tissues(n=86). Results The expression positive rate of CD105 protein was 74. 4%(64/86) in esophageal squamous cell carcinoma , 0% in normal esophageal epithelium. Expression positive rate of CD105 protein was 66. 1%(37/56) in early stage (stage Ⅰ-Ⅱ ), 90.0% (27/30) in later stages (stage Ⅲ-Ⅳ ). The expression of CD105 protein were bly associated with P53 protein(P〈0. 05). Conclusion CD105 protein may participate in the onset and progression of esophageal squamous cell carcinoma. CD105 protein could he a new diagnostic /therapeutic target in esophageal squamous cell carcinoma.
Objective To evaluate the effect of mechanical suture in surgery of esophageal carcinoma,Methods Five hundred and sixty-eight cases of esophagogastrostomy and esophagojejunostomy for esophageal and cardiac carcinoma were collected in our hospital between January, 1988 and December, 2002. They were devided into two groups according to the methods of anastomoses, the group by stapler and the group with hand. The incidence of postoperative complications in the two groups was compared. Results The time of esophagogastrostomy, the total operating time, and postoperative fasting time of group by stapler were shorter than those of group with hand (Plt;0. 01), and there was no statistically difference in the median hospitalized time after operation for two groups. The anastomotic leakage, anastomotic stricture, anastomotic bleeding , incidence of postoperative complications in respiration and circulation and mortality rate of group by stapler were lowed than those of group with hand (2.1%, 1.4%,0%,2.8% and 0.7% vs.6.8%,4.3%,1.4%,16.5% and 2.9%). There was no statistical difference in the postoperative gastro-esophageal reflux for two groups (P 〉 0.05 ). Conclusion The median time of esophagogastrostomy and the median operating time by stapler are decreased and the incidence of postoperative complications is decreased.
