Résumé
Objective To evaluate the clinical feature of malignant ameloblastoma. Methods A review of 25 cases of malignant ameloblastoma was presented with respect to age, sex, primary site and times of recurrence, site and time of metastasis, results of follow up, pathological type. Results Male patients outnumbered female patients by 1.5 to1. The median age at which the primary tumor was first treated was 30.5 years. The primary sites were mandible(17), maxilla(5), tibia(1), rib(1), ulna(1). The most metastases were found in lung(80%), with cervical lymph nodes and liver each representing 24% and 12% of the metastatic sites. Other sites of metastasis included brain(1), femur(1), thoracic spine(1), spleen(1), myocardial(1), mediastinum(1). The median times of primary recurrence was 2.5 times. The median survival time after metastasis was 2 years. There were four pathological types which were follicular type(4), plexiform type(2), acanthomatous type(1), granular type(1). Conclusins Multiple recurrences developed in most of the 25 patients. The time between diagnosis of primary tumor and appearance of metastasis in 25 patients was long. The most frequent sites of metastasis was lung and cervical lymph nodes. Early adequate resection of the primary tumor to avoid repeated surgical intervention is advocated to prevent tumor spread.
Résumé
Objective To evaluate result of invaginative esophagogastroanastomosis to prevent the leakage,anastomotic stenosis and reflux esophagitis in esophagectomy.Methods A method of invaginative esophagogastroanastomosis with esophageal mucus to gastric mucus and gastric seromuscular to esophagic nuscular were done in 148 cases cardiac cancer and 120 cases esophageal cancers.Gastro-esophagus full-thickness anastomosis were done in the control group including 112 cases cardiac cancer and 98 cases.Standardized rate and standard error toanalysis the date were adopted.Results It had significant difference between the two groups.Conclusion This anastomosis could avoid the esophagogastroanastomotic leakage,anastomotic stenosis and reflux esophagitis effectively.
