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：探討3D網塞在腹股溝疝修補術中的應用。方法：隨機選取30例腹股溝疝患者用3D網塞行無張力疝修補術。結果：本組平均手術時間35 min，平均術中出血15 mL。術后8~24 h下地活動，均未給鎮痛藥，無手術死亡、無切口感染、陰囊血腫等并發癥，患者局部舒適性好，異物感不明顯，隨訪5~10個月，無一例復發。結論：使用3D網塞作為充填式疝修補材料具有手術創傷小、恢復快，患者局部舒適性好，復發率低等優點。
