改良Sublay-Keyhole技术原位修补造口旁疝

目的探讨改良Sublay-Keyhole技术原位修补造口旁疝的方法及疗效。方法 2007年10月-2010年3月,采用改良Sublay-Keyhole技术原位修补造口旁疝11例。男5例,女6例;年龄55～72岁,平均63岁。体重指数为23.5～32.5,平均28.2。患者均为永久性造瘘,其中6例为低位直肠癌行Miles术式后的乙状结肠末端造瘘,2例为溃疡性结肠炎行全结肠切除术后的回肠末端造瘘,3例为膀胱癌行回肠代膀胱术后的回肠末端造瘘。1例患者既往曾行聚丙烯补片修补后复发。末次手术至该次入院时间为1～4.5年,平均2.5年。根据George Eliot医院分类标准:2b级3例,3a级2例,3b级5例,4级1例。疝环最长径为6～12cm,平均9.5cm。结果 11例均以改良Sublay-Keyhole技术成功完成腹壁重建手术。术中测量疝环面积为30～112cm2,平均75.5cm2;应用聚丙烯补片面积为175～360cm2,平均280.5cm2。手术时间120～195min,平均165min;术后住院时间9～14d,平均11d。术后患者切口均Ⅰ期愈合,无腹壁感染发生。2例(18.2%)发生血清肿,1例(9.1%)发生腹壁血肿,对症处理后愈合。11例均获随访,随访时间10～39个月,平均26.3个月。1例(9.1%)于术后11个月造口旁疝复发,再次修补手术时发现疝环关闭处缝线松脱同时补片孔洞过于宽大,予以缝合缩窄后随访15个月无复发;其余10例患者术后未见造口旁疝复发或发生其他切口疝。结论改良Sublay-Keyhole技术是造口旁疝患者腹壁重建的有效方法,具有复发率低、并发症少等优点,但远期疗效需进一步观察随访。

Repair in situ of parastomal hernia with modified sublay-keyhole technique

Objective To investigate the procedure and the effectiveness of modified Sublay-Keyhole technique for repair in situ of parastomal hernia.Methods Between October 2007 and March 2010,11 patients with parastomal hernia underwent modified Sublay-Keyhole technique for repair in situ.There were 5 males and 6 females with an average age of 63 years(range,55-72 years).The average body mass index was 28.2(range,23.5-32.5).All stomas in patients were permanent,including 6 end colostomies caused by abdominal perineal...
