目的 探讨改良纵切横缝术与肛裂切除术治疗肛裂患者的临床对比探究。方法 选择2015年12月—2020年12月行肛裂手术的98例患者作为对象,随机分为对照组（n=49）和观察组（n=49）。对照组予以肛裂切除术,观察组采用改良纵切横缝术,比较两组临床治疗有效性、两组治疗后并发症情况、两组肛管直径变化及切口愈合时间。结果 观察组临床治疗总有效率（91.84%）高于对照组的（84.44%, P<0.05）。观察组出现水肿、疼痛、感染、便血、便秘的总发生率（8.16%）低于对照组（36.73%, P<0.05）。两组术后肛管直径指数均有所提升,观察组临床治疗效果显著于对照组（P<0.05）;观察组切口愈合时间少于对照组（P<0.05）。结论 改良纵切横缝术与肛裂切除术均可治疗肛裂患者,但改良纵切横缝术能够显著提升临床治疗疗效,降低术后并发症发生率,化解患者疾病痛苦程度,值得推广应用。

Objective To investigate the clinical effects of modified longitudinal section and and transverse suture and anal fissure resection on anal fissure. Methods A total of 98 patients with anal fissure from December 2015 to December 2020 were selected as study subjects and randomly divided into a control group （n=49） and an observation group （n=49）. The control group was treated with anal fissure resection, and the observation group was treated with modified longitudinal section and transverse suture. The clinical treatment effectiveness, complications after treatment, anal canal diameter changes, and incision healing time of the two groups were compared. Results The total effective rate of the observation group was 91.84%, higher than that of the control group （84.44%, P<0.05）. The observation group’s total incidence rate of edema, pain, infection, hematochezia, and constipation was 8.16%, lower than that of the control group （36.73%, P<0.05）. The diameter index of anal canal was increased in both groups, and the clinical treatment effect of the observation group was significantly higher than that of the control group （P<0.05）, while the wound healing time of observation group was shorter （P<0.05）. Conclusion Both the modified longitudinal section and transverse suture and the anal fissure resection can treat patients with anal fissure, but the former surgery can significantly improve clinical therapeutic effects, reduce the incidence of postoperative complications, and relieve pain, which is worthy of popularization and application.
