The anorectal anomalies consist in a complex group of birth defects. Laparoscopic-assisted anorectoplasty improved visualization of the rectal fistula and the ability to place the pull-through segment within the elevator muscle complex with minimal dissection. There is no consensus on how the fistula should be managed.
To evaluate the laparoscopic-assisted anorectoplasty and the treatment of the rectal urinary fistula by a bipolar sealing device.
It was performed according to the original description by Georgeson1. Was used 10 mm infraumbilical access portal for 30º optics. The pneumoperitoneum was established with pressure 8-10 cm H2O. Two additional trocars of 5 mm were placed on the right and left of the umbilicus. The dissection started on peritoneal reflection using Ligasure(r). With the reduction in the diameter of the distal rectum was identified the fistula to the urinary tract. The location of the new anus was defined by the location of the external anal sphincter muscle complex, using electro muscle stimulator externally. Finally, it was made an anastomosis between the rectum and the new location of the anus. A Foley urethral probe was left for seven days.
Seven males were operated, six with rectoprostatic and one with rectovesical fistula. The follow-up period ranged from one to four years. The last two patients operated underwent bipolar sealing of the fistula between the rectum and urethra without sutures or surgical ligation. No evidence of urethral leaks was identified.
There are benefits of the laparoscopic-assisted anorectoplasty for the treatment of anorectal anomaly. The use of a bipolar energy source that seals the rectal urinary fistula has provided a significant decrease in the operating time and made the procedure be more elegant.
肛门直肠畸形是一组复杂的出生缺陷。腹腔镜辅助肛门直肠成形术改善了直肠瘘的可视化,以及在最小程度的解剖下将拖出段置于提肌复合体中的能力。关于如何处理瘘管尚无共识。
评估腹腔镜辅助肛门直肠成形术及使用双极密封装置治疗直肠尿道瘘。
按照乔治森1的原始描述进行手术。使用10mm脐下入口通道用于30°光学观察。以8-10cmH2O的压力建立气腹。在脐部右侧和左侧再放置两个5mm的套管针。使用结扎速血管闭合系统从腹膜返折处开始解剖。随着直肠远端直径减小,确定通向泌尿道的瘘管。使用外部肌肉电刺激器,根据肛门外括约肌复合体的位置确定新肛门的位置。最后,在直肠与新肛门位置之间进行吻合。留置一根Foley尿道探子7天。
7例男性接受手术,6例为直肠前列腺瘘,1例为直肠膀胱瘘。随访期为1至4年。最后2例手术患者在直肠与尿道之间的瘘管采用双极密封,无需缝合或手术结扎。未发现尿道渗漏迹象。
腹腔镜辅助肛门直肠成形术治疗肛门直肠畸形有诸多益处。使用双极能量源封闭直肠尿道瘘显著缩短了手术时间,使手术过程更加精细。
