狭长U形槽状切口在坐骨直肠间隙脓肿和坐骨直肠间隙肛瘘手术中的应用价值

为探讨狭长U形槽状切口在坐骨直肠间隙脓肿和坐骨直肠间隙肛瘘手术中的应用价值，回顾分析采用常规底小口大切口手术（对照组，205例）和狭长U形槽状切口手术（治疗组，232例）治疗的脓肿及肛瘘患者资料，对比分析两种切口对创面愈合的影响。结果显示，两组患者均痊愈出院。治疗组平均创面愈合时间（22．4d）明显短于对照组（27．7d），P〈0．05。随访半年以上，治疗组创口无异常；对照组21例（10．2％）创口表层组织颜色变黑，7例（3．4％）创口愈合后又自行坏死溃烂。结果表明，狭长U形槽状切口有利于切口较深的坐骨直肠间隙脓肿和坐骨直肠间隙肛瘘的痊愈；

Application of U-shaped Narrow and Long Groove Incision in the Procedure for Ischiorectal Space Abscess and Ischiorectal Space Anal Fistula

For the objective of evaluating the applicable value of U-shaped narrow and long groove incision in the procedure for ischiorectal space abscess and ischiorectal space anal fistula, authors analysed the data of 437 patients with abscess or anal fistula,among them 205 cases selected as controlled group were subject to routine incision with larger mouth and smaller bottom, rest 232 cases to U-shaped narrow and long groove incision,as treatment group, compared and analysed the impacts of the two different incisions on healing of wound. As results,the patients of both groups were all cured and discharged;the average wound healing time of treatment group was greatly shorter than that of controlled group（22.4 d vs 27.7 d, P 0.05） ;after follow-up of 0.5 yr. the wound was still normal in treatment group, but in controlled group the wound superficial tissue of 21 cases（10.2% ,21/205） became blacken,the wound of 7 cases （3.4% ,7/ 205） was again of necrosis and ulcer by one-self following healing. Results show that U-shaped narrow and long groove incision is helpful to cure of ischiorectal space abscess and ischiorectal space anal fistula.
