ObjectiveTo study the advance of malignant anorectal melanoma. MethodsThe literature in recent years about risk factors,clinical characteristic,early diagnosis,treatment and the prognosis of the anorectal melanoma were reviewed.ResultsMalignant anorectal melanoma was very rare.The history of pigment naevus,human immunodeficiency virus infection and sunlight exposure might be the risk factors.Clinic characteristics were rectal bleeding,anorectal mass and changing in bowel habits.Early diagnosis mainly depended on performing routine examination on patients between the ages of 45-80 years.The staining for polycolnal CEA in anorectal melanoma has a role on diagnostic pathology.The treatment is controversial and the combined treatments of chemotherapy with radiation therapy and immunotherapy which were based on surgery (abdominoperineal resection or wide local excision) are introduced.Conclusion Early diagnosis of malignant anorectal melanoma is difficult and the prognosis is poor.It is necessary to pay more attention to this disease and the most successful therapeutic approaches need to be developed.
目的：探讨3D网塞在腹股沟疝修补术中的应用。方法：随机选取30例腹股沟疝患者用3D网塞行无张力疝修补术。结果：本组平均手术时间35 min，平均术中出血15 mL。术后8~24 h下地活动，均未给镇痛药，无手术死亡、无切口感染、阴囊血肿等并发症，患者局部舒适性好，异物感不明显，随访5~10个月，无一例复发。结论：使用3D网塞作为充填式疝修补材料具有手术创伤小、恢复快，患者局部舒适性好，复发率低等优点。
