腹腔镜辅助阴式子宫切除术32例临床分析

    Laparoscopic-assisted vaginal hysterectomy: A report of 32 cases

    • 摘要: 目的: 探讨腹腔镜辅助阴式子宫切除手术(laparoscopic-assisted vaginal hysterectomy,LVAH)方法及临床应用价值。方法: 对2004年1月~2005年10月32例子宫肌瘤、子宫腺肌病、功能性子宫出血、子宫颈不典型增生等有子宫切除指征的患者行LAVH。结果: 32例中31例成功,中转开腹1例,成功率96.9%(31/32)。结论: LAVH在妇科手术中具有创伤小、痛苦轻、康复快的优点。

       

      Abstract: Objective: This study was designed to characterize the ultrastructure of the coccoid Helicobacter pylori(H. pylori) forms in the tissues of carcinoma.Methods: Transmission electron microscopy(TEM) technique was used to examine the structure of coccoid H. pylori in 4 cases of gastric carcinoma and 2 cases of esophageal carcinoma.Results: It was found that the coccoid H. pylori were scattered in cancer nest and cancer interspace,some of which enterded cancer cells,macrophages and other cells.The coccoid H. pylori appeared to be similar to the L-forms of other bacteria with varying cell shape and size,different cytoplasmic electron densities and defects in cell wall.Two types of coccoid H. pylori could be distinguished in the tissues of carcinoma by TEM.Type A was smaller with higher electron density in the cytoplasma,and flagellation on the cell membrane,suggesting that it could be viable.However,the type B was larger with lower electron density in the cytoplasma,and no flagellation on the cell membrane,suggesting that it could be a degenerative form.Conclusions: The coccoid forms of H.pulori still have certain degree of viability,thus they may play an important role in the transmission of H. pylori,the relapse of H. pylori related disease after treatment and the development of the related carcinoma.
