Laparoscopic orchiopexy for intra-abdominal testis is a well-known and commonly practiced technique. The traction technique is based on elongation of the testicular vessels without cutting them, in contrast with the two-stage Fowler-Stephens technique in which the testicular vessels are divided. The current study evaluated the feasibility of the traction technique according to the type of intra-abdominal testis.
The study included 20 boys with 22 intra-abdominal testes and who underwent staged laparoscopic traction orchiopexy between October 2013 and October 2015. Eighteen testes were proximal to the internal ring by <2 cm (type III), while the remaining four were high and away from the internal ring by >2 cm (type IVa). The patients' ages ranged between 6 months and 5 years (mean 2.2 years; median 2 years). Patients were followed up for 1 year for testicular atrophy and satisfactory scrotal site relocation.
This study did not detect any cases of testicular atrophy among the participants (0/22), while failure to achieve satisfactory scrotal site was found in two out of the four cases with type IVa intra-abdominal testes.
Traction techniques for elongating the testicular vessels were employed years ago, but this was revisited by Shehata in 2008. It has the advantage of preserving the main testicular blood supply, which can be reflected by the decreasing rate of testicular atrophy when compared with the Fowler-Stephens orchiopexy. The results of the traction technique may be less satisfactory regarding the testicular location for higher types of intra-abdominal testes (type IVa).
Staged laparoscopic traction orchiopexy was a feasible technique for intra-abdominal testes (within 2 cm of the internal ring), but the results were less satisfactory when applied for higher intra-abdominal testes (type IVa).
腹腔镜睾丸固定术治疗腹腔内隐睾是一种众所周知且广泛应用的技术。牵引技术基于延长精索血管而不切断它们,与两阶段 Fowler-Stephens 技术不同,后者需要切断精索血管。本研究根据腹腔内隐睾的类型评估了牵引技术的可行性。
本研究纳入了 2013 年 10 月至 2015 年 10 月期间接受分期腹腔镜牵引睾丸固定术的 22 例腹腔内隐睾男孩。18 例睾丸距离内环 <2cm(III 型),其余 4 例睾丸距离内环 >2cm(IVa 型)。患者年龄 6 个月至 5 岁(平均 2.2 岁;中位数 2 岁)。所有患者均随访 1 年,以评估睾丸萎缩和满意的阴囊位置。
本研究未发现任何参与者出现睾丸萎缩(0/22),但 4 例 IVa 型腹腔内隐睾中,有 2 例未达到满意的阴囊位置。
延长精索血管的牵引技术多年前就已应用,但 Shehata 于 2008 年重新审视了这一技术。该技术的优点是保留了主要的睾丸血供,与 Fowler-Stephens 睾丸固定术相比,睾丸萎缩的发生率降低。对于较高类型的腹腔内隐睾(IVa 型),牵引技术在睾丸位置方面的效果可能不太理想。
分期腹腔镜牵引睾丸固定术是治疗腹腔内隐睾(距离内环 2cm 以内)的可行技术,但对于较高位置的腹腔内隐睾(IVa 型)效果较差。
