Abstract:Objective To investigate the safety and feasibility of different pretreatment methods in laparoscopic salpingotomy for tubal pregnancy.Methods Retrospective case-control analysis was conducted to analyze the clinical data of 120 patients with unruptured tubal pregnancy who underwent laparoscopic fenedotomy for tubal pregnancy from October 2014 to October 2018. According to the combination of epinephrine, the patients who met the requirements were divided into two groups. The control group (n = 58): 6 u hypophysin injection was injected between the horn of uterus posteriorly and ovarian proper ligament, Observation group (n = 62): At the same time of the above treatment, 5 mL diluted epinephrine saline (1∶1 200) was injected into the mesosalpinx of the lesion. After two treatments, the operative time, intraoperative blood loss, β-human chorionic gonadotropin(β-HCG) negative time, and the incidence of persistent ectopic pregnancy were observed in both groups.Results The operative time, intraoperative blood loss and negative conversion time of β-HCG in observation group were all lower than those in control group (P < 0.05).Conclusion Combined application of pituitrin and epinephrine can effectively reduce intraoperative blood loss, shorten the operative time and the negative turning time of β-HCG, which is a safe and feasible method.
