目的探讨包皮环切术后切口狭窄环形成的机制及处理方法。方法对包皮过长或包茎220例行包皮环切术,采取三种不同止血方式,比较其术后切口狭窄环的发生率。结果高频电刀电凝组术后切口狭窄环发生率最高,为8.3%;双极电凝组次之,为3.3%;丝线打结止血组未出现切口狭窄环。结论高频电凝止血通过高频电流对组织产生热效应,潜在损伤范围大,皮下组织容易引起粘连,导致切口狭窄环形成。切口狭窄环一旦形成,须早期手术治疗。
Objective To investigate the mechanism and treatment of stenosis ring after circumcision. Methods 220 cases of prepuce or phimosis circumcision, take three different ways to stop bleeding, compare the incidence of postoperative incision stenosis ring. Results The frequency of electrosurgical coagulation was the highest (8.3%). The bipolar electrocoagulation group was the second (3.3%). There was no incision stenosis ring in the wire knot hemostasis group. Conclusion High-frequency electrocoagulation hemostasis generates thermal effects on the tissue through high-frequency current, and the potential damage range is large. Subcutaneous tissue easily causes adhesions, resulting in the formation of a narrow ring of incision. Narrow incision ring once formed, to be early surgical treatment.
