目的研究首次剖宫产术式选择对二次妇产科手术的影响。方法选取我院近年收治的有剖宫产术史的再次妇产科手术患者126例,根据首次剖宫产术式分为传统组42例(传统子宫下段剖宫产术)、新式组40例(新式剖宫产术)及改良组44例(改良新式剖宫产术),比较二次妇产科手术时3组围术期手术时间、切口并发症及盆腹腔粘连情况。结果改良组在手术时间、切口并发症上均明显低于传统组,差异有统计学意义(P<0.05),略低于新式组,差异无统计学意义(P>0.05)。但在盆腹腔粘连和严重粘连上,改良组均显著低于传统组和新式组,差异有统计学意义(P<0.01)。结论改良新式剖宫产术患者行再次妇产科手术时,手术时间、切口并发症、盆腹腔粘连及严重粘连发生率均明显降低,更加具有高效性和安全性。 Objective To study the effect of the first cesarean section on secondary obstetrics and gynecology. Methods 126 cases of re-obstetrics and gynecology patients with history of cesarean section admitted in our hospital in recent years were enrolled. According to the first cesarean section, 42 cases were divided into traditional group (traditional cesarean section), 40 cases (New cesarean section) and modified group (44 cases modified neo-caesarean section), and compared the operation time, incision complications and pelvic adhesions in the three obstetrics and gynecology operations. Results The operation time and incision complications in the modified group were significantly lower than those in the traditional group (P <0.05), slightly lower than those in the new group, with no significant difference (P> 0.05). But in the pelvic adhesions and severe adhesions, the modified group were significantly lower than the traditional group and the new group, the difference was statistically significant (P <0.01). Conclusions In the patients with improved new cesarean section, the recurrence of obstetrics and gynecology, operation time, incision complications, pelvic adhesions and severe adhesions were significantly lower, more efficient and safe.
