Objective To study the clinical curative effect of transvaginal and laparoscopic operation methods for treating exogenous uterine cesarean scar pregnancy.Methods Sixty patients with exogenous uterine CSP in our hospital from August 2013 to August 2016 were selected and divided into the two groups with 30 cases in each group.The control group adopted laparoscopic lesion resection,while the observation group adopted transvaginal lesion excision of lower uterine segment.Then the operation situation,postoperative VAS score,β-HCG levels and traumatic response indexes were compared between the two groups.Results The hospitalization time had no statistical difference between the two groups(P＞0.05).The hospitalization cost,blood loss volume and anal exhaustion time in the observation group were less than those in the control group(P＜0.05).The β-HCG level before and after operation had no statistical difference between the two groups (P＞0.05).The VAS score and traumatic response indexes in the observation group were better than those in the control group(P＜0.05).The complication occurrence rate in the observation group was lower than that in the control group(P＜0.05).Conclusion Transvaginal lesion excision of lower uterine segment in the treatment of exogenous uterine CSP has better curative effect and safety.
