腹腔镜辅助中位肛门闭锁成形术11例报告

目的 探讨腹腔镜辅助中位肛门闭锁成形术的可行性。方法 腹腔镜监视下,游离松解直肠;断离修补直肠尿道（阴道）瘘管,其中6例经腹腔镜离断修补,4例经会阴切口离断修补;然后在电刺激仪的引导下经会阴肌肉中心1.0cm左右小切口向盆底肌肉中心分离形成隧道,最后将直肠从隧道中拖出,与会阴皮肤吻合,同时关闭结肠造瘘口。结果 11例患儿均在腹腔镜辅助下完成肛门成形术,腹腔镜手术操作时间平均32.8min（25～78min）,出血量平均5.3ml（2～10ml）,无需要输血者。术后11d去除尿管或膀胱造瘘管,无尿道瘘或憩室出现,无切口感染发生。11例术后随访3～66个月,平均45个月。根据肛门功能临床评分标准评分（6分法）,排便优8例（72.7%）,良3例（27.3%）。结论 腹腔镜辅助中位肛门闭锁成形术处理直肠泌尿系瘘方便,辨认盆底肌中心准确及避免切口污染等优点,是治疗中位肛门闭锁有效方法。

Laparoscopically assisted anorectoplasty for intermediate imperforate anus: A report of 11 cases

Objective To explore the feasibility of laparoscopically assisted one-stage anorectoplasty for the treatment of intermediate imperforate anus. Methods Under laparoscopic visualization, the rectum was mobilized. Then the rectourethral (or rectovaginal) fistula was repaired laparoscopically (6 cases) or through perineal approach (4 cases). Afterwards a tunnel was made through the center of pelvic floor musculature by combined use of laparoscopic and perineal approach. The rectum was pull-through the perineum and anastomosed with skin. At Last the colostomy was closed. Results Laparoscopically assisted anorectal pull-through was successfully performed in all cases. The mean duration of laparoscopic dissection was 32.8 minutes (range, 25~78 minutes). The mean blood loss was 5.3 ml (range, 2~10 ml). No blood transfusion was needed. The intraurethral catheter or cystostomy tube was removed on the 11th postoperative day. No intraoperative complication was encountered and all infants had uneventful postoperative recovery without wound infection. During a follow-up for 3~66 months (mean, 45 months), the fecal continence evaluation showed excellent in 8 cases and good in 3 cases. Conclusions Laparoscopically assisted anorectoplasty is an effective and minimally invasive technique for the treatment of intermediate imperforate anus. This technique has advantages of simple performance, accurate identification of the center of the pelvic floor musculature, and low infection rate.
