Objective: To investigate the effect of modified Bianchi (single incision in the midline of the scrotum) orchiopexy (MBO) versus that of traditional surgery in the treatment of median or low cryptorchidism.
Methods: Eighty-two children with median or low cryptorchidism were treated from February 2013 to February 2014, 46 (53 testes) by MBO and the other 36 by the traditional method of inguinal incision (control, 40 testes). Comparisons were made in the operation time and postoperative complications between the two surgical strategies.
Results: The mean operation time was significantly shorter in the MBO group than in the control (［25±6］ vs ［35±4］ min, P<0.05). No testicular atrophy, hernias or hydrocele was found in either group during the 1－2 years of follow-up. Testis retraction was observed in 3 cases in the MBO group as compared with 2 in the control (P>0.05). The incision scar was obvious in all the controls, with 1 case of postoperative inguinal hematoma, but almost invisible in all the MBO cases.
Conclusions: Modified Bianchi orchiopexy is superior to traditional surgery in the treatment of median or low cryptorchidism for its advantages of short operation time, few complications, and satisfactory appearance of the healed incision.
目的： 探讨改良Bianchi（阴囊中缝切口）睾丸下降固定术与传统（腹股沟联合阴囊切口）睾丸下降固定术的优缺点。方法： 2013年2月至2014年2月收治的 所有82例中低位隐睾患儿中，随机对其中46例(53侧睾丸)行改良Bianchi睾丸下降固定术作为观察组；传统方法即经腹股沟联合阴囊切口治疗36例(40侧)作为对照组。 比较2组手术时间、术后并发症等方面的差异。结果： 观察组与对照组患儿的手术时间分别为(25±6) min和(35±4) min，两组比较差异有统计学意义 (P<0.01)；经过1~2年的随访比较，均未出现睾丸萎缩情况；观察组患儿出现3例睾丸上缩情况，对照组出现2例术后睾丸上缩，发生率的差异没有统计学意义；术 后均未出现腹股沟斜疝、鞘膜积液的并发症，但对照组患儿有1例出现腹股沟处切口血肿且所有患儿切口均较明显，而观察组术后手术切口几乎观察不到。结论： 行 改良Bianchi睾丸下降固定术治疗中低位隐睾效果满意，较传统手术在手术时间和切口美观等方面具有一定的优势，值得临床推广。.
