由于会阴部解剖的特点，烧伤后极易出现瘢痕挛缩和粘连，造成肛门狭窄导致严重的功能障碍。本文报告１４例，其中假性肛门狭窄１２例，真性狭窄２例。儿童占７８．６％。为克服单纯瘢痕松解植皮后发生再度挛缩的缺点，作者改良了手术方法，对假性肛门狭窄，利用狭窄口转折处环形切开所形成的两层组织瓣。以三对４５°～６０°角的对偶三角皮瓣交叉缝合。对真性肛门狭窄采用在截石位１、５、９点分别作放射切开松解瘢痕，并切断肛门外括约肌的皮下部，继发创面植以三块楔形全厚皮片的办法，形成瘢痕－全厚皮片－粘膜相间的车轮状肛门外形。术后３～６个月随访９例，均排便功能正常，肛门外形改善，未发现再度挛缩病例。文中对两类肛门狭窄的形成过程，鉴别诊断，合并症的处理进行了讨论，并详细地介绍了手术方法，作者认为该方法简单易行，充分利用了瘢痕和残存的皮肤组织，有效地预防了再度肛门狭窄的发生。
Due to the characteristics of the perineal anatomy, burns prone to scar contracture and adhesions, resulting in anal stenosis leading to serious dysfunction. This article reports 14 cases, including pseudo-anal stenosis in 12 cases, 2 cases of true stenosis. Children make up 78.6%. In order to overcome the shortcoming of reoccurrence of contracture after pure scar release skin graft, the authors modified the surgical method and used two-layer tissue flap formed by ring-shaped incision on the fake anal stenosis. Three pairs of 45 ° ~ 60 ° angle dual triangular flap cross stitching. The true anal stenosis in the lithotomy position 1,5,9 points were cut for radioactive release of scar and cut off the external anal sphincter subcutaneous, secondary wound planted with three wedge-shaped full-thickness skin approach to the formation of scars - Full thickness skin - mucous membrane wheel shape anal appearance. Nine cases were followed up 3 to 6 months after operation, all had normal defecation, improved anal appearance, and no recurrence of contracture. This article discusses the formation of two types of anal stenosis, differential diagnosis, treatment of complications were discussed in detail and introduced the surgical method, the authors believe that the method is simple and easy to take full advantage of the scar and residual skin tissue, effective prevention Once again, the occurrence of anal stenosis.
