We describe the use of a gastric segment in performing the antegrade continence enema procedure in patients with refractory fecal incontinence.
The antegrade continence enema procedure was performed in 4 women and 3 men with refractory neurogenic fecal incontinence. Preoperative evaluation included defecography and anorectal manometry. Operative technique involves tunneling a 10 cm. segment of tubularized stomach isolated along the greater curve with preservation of the right gastroepiploic vessels through the anterior tenia of the colon just distal to the splenic flexure. After the stoma is mature the patient passes a catheter and runs 1 to 2 l. warm tap water through it while seated on the toilet. Digital stimulation may be required to initiate bowel emptying and irrigation is continued until clear.
Creation of a nonrefluxing catheterizable gastric tube to the descending colon was successful in all 7 patients. At a mean postoperative followup of 22.4 months all patients are continent and use antegrade continence enema irrigation every other day on average. One patient required early revision because of stomal stenosis. Special measures include application of a generic antacid tablet to the stoma and use of a skin barrier.
Catheterizable access to the descending colon for the antegrade continence enema procedure more closely approximates normal defecation patterns by emptying ("unloading") the left side of the colon. The stomach is a suitable option in close proximity for this purpose and is especially advantageous when the appendix is not available. The antegrade continence enema procedure using a gastric segment can be safely and effectively performed, and is well suited for use by reconstructive surgeons who are familiar with the Mitrofanoff principle.
我们描述了胃段在难治性大便失禁患者行顺行性节制灌肠手术中的应用。
对4名女性和3名男性难治性神经源性大便失禁患者实施顺行性节制灌肠手术。术前评估包括排粪造影和肛门直肠测压。手术技术包括沿胃大弯游离一段10厘米长的管状胃,保留右胃网膜血管,经脾曲远端结肠的结肠带前方穿出。造口成熟后,患者坐在马桶上经导管注入1至2升温自来水。可能需要通过手指刺激启动排便,持续冲洗直至流出物清澈。
7例患者均成功建立了无反流的可插管的胃管至降结肠。术后平均随访22.4个月,所有患者均能控制排便,平均每隔一天进行一次顺行性节制灌肠冲洗。1例患者因造口狭窄需要早期修复。特殊措施包括在造口处应用普通抗酸片和使用皮肤保护剂。
通过排空(“卸载”)结肠左侧,顺行性节制灌肠手术中可插管进入降结肠更接近正常排便模式。胃是实现此目的的合适临近器官选择,在无法利用阑尾时尤其有利。使用胃段的顺行性节制灌肠手术可安全有效地实施,非常适合熟悉米氏原理的重建外科医生使用。
