目的探讨腹部横切口剖宫产改良术的临床价值。方法于下腹部两髂前上棘连线下２～３ｃｍ处做横行直切口，钝性分离脂肪层及腹直肌，横向撕开腹膜，肠线单层连续缝合子宫肌层，不缝合腹膜，肠线连续缝合筋膜及间断全层缝合皮肤及皮下组织。并与同期腹部纵切口剖宫产术进行比较。结果改良式手术时间短，术中失血量少，术后肛门排气时间缩短伤口疼痛轻，术后病率低，住院时间短。与对照组比较差异有显著性（Ｐ＜０．０５～０．０１）。结论改良腹部横切口剖宫产术手术时间短，术后并发症少；腹壁切口疤痕易被腹壁皱褶遮盖。不影响体表美观，孕妇易接受，值得临床推广应用 Objective To investigate the clinical value of cesarean section improvement in abdominal transverse incision. Methods The lateral anterior superior iliac spine in the lower abdomen 2 ~ 3cm under the line to do horizontal straight incision, blunt dissection of fat and rectus abdominis, transverse peritoneal perforation, catgut single continuous suture myometrium, not peritoneal suture, Gut continuous suture fascia and intermittent full-thickness sutured the skin and subcutaneous tissue. And compared with the same period of abdominal incision cesarean section. Results The results showed that the time of modified operation was short, blood loss was less, the exhaust time of anus was shorter, the wound pain was lighter, the postoperative morbidity was lower and the hospitalization time was shorter. Compared with the control group, the difference was significant (P <0.05 ~ 0.01). Conclusion The modified abdominal transverse incision cesarean section operation time is short, less postoperative complications; abdominal incision scar easily covered by the abdominal wall folds. Does not affect the appearance of beautiful, pregnant women easy to accept, worthy of clinical promotion and application
