腹腔镜保守性手术治疗输卵管妊娠的效果及其影响因素分析

目的 探讨腹腔镜保守性手术治疗输卵管妊娠的效果及其影响因素.方法 2003年1月至2008年12月,对北京安贞医院妇产科226例输卵管妊娠者行腹腔镜保守性手术治疗,152例于术后3～6个月行子宫输卵管造影,其中6例接受了再次腹腔镜探查,以评价手术侧输卵管是否通畅.第1次腹腔镜手术成功207例,手术失败19例;术后3～6个月行子宫输卵管造影,第1次腹腔镜手术成功的207例患者中,患侧输卵管通畅者89例(A组);第1次腹腔镜手术失败、术中及术后改行输卵管切除术(19例)及手术后随访检查患侧输卵管不通者(63例)共计82例(B组).再以妊娠包块最大径线5 cm或血清人绒毛膜促性腺激素(hCG)水平≤2000 IU/L,>2000～<5000 IU/L,≥5000 IU/L为界,分别计算输卵管通畅率.两组患者年龄、孕次、停经时间、输卵管妊娠的侧别及部位、是否破裂、是否合并盆腔粘连等方面比较,差异均无统计学意义(P>0.05).结果 226例患者中,207例患者第1次腹腔镜手术成功,手术成功率为91.6%(207/226),术后3～6个月随访152例,失访55例.A、B组患者术前血清hCG中位水平分别为980(55～12 000)、3150(570～40 000)IU/L,两组比较,差异有统计学意义(P<0.01);A、B组患者输卵管妊娠包块最大径线分别为(3.4±1.3)、(5.0±1.7)cm,两组比较,差异也有统计学意义(P<0.01).A组患者术前中位腹腔内出血量为200(0～1500)ml,B组为300(0～1600)ml,A组活胎率为2%(2/89),B组为11%(9/82),两组比较,差异均有统计学意义(P<0.05).两组共171例患者中,妊娠包块最大径线<5 cm者103例,术后患侧输卵管通畅率为65%(67/103),妊娠包块最大径线≥5 cm者68例,术后患侧输卵管通畅率为32%(22/68),两者比较,差异有统计学意义(P<0.01);血清hCG水平≤2000 IU/L、>2000～<5000 IU/L、≥5000 IU/L者术后患侧输卵管通畅率分别为72%(73/102)、29%(12/42)和15%(4/27),3者分别比较,差异也有统计学意义(P<0.05);logistic回归分析结果显示,术前血清hCG水平(OR=0.277,P<0.01)、输卵管妊娠包块最大径线(OR=0.577,P<0.01)、腹腔内出血量(OR=0.999,P<0.05)均为手术成功率的影响因素.结论 腹腔镜保守性手术对输卵管妊娠希望保留输卵管功能的患者具有安全性和可行性;术前血清hCG水平、输卵管妊娠包块大小及腹腔内出血量是影响手术效果的重要因素.

Outcome and relevant factors of tubal pregnancy treated with laparoscopic conservative surgery

Objective To investigate the therapeutic outcome and its influencing factors after laparoscopic conservative surgery in treatment of tubal pregnancy. Methods From January 2003 to December 2008, 226 cases with tubal pregnancy were treated by laparoscopic conservative surgery. The tubal pateacy was evaluated in 152 cases given by hysterosalpingography (HSG) and 6 cases given by second laparoscopic exploration at 3-6 months after surgery. In their first laparoscopic surgeries, 209 got successful treatment and 19 underwent fail treatment. At 3-6 months after surgery, 89 cases with tubal patency among 207 cases with successful treatment were enrolled in group A. Nineteen cases who were failed in their first laparoscopic conservative surgery and treated by salpingectomy and 63 cases with tubal obstruction were enrolled in group B. The rate of tubal patency was calculated on patients with characteristics of gestational sac less or more than 5 era, the level serum human chorionic gonadotropin (hCG) less than 2000 IU/L,2000 IU/L to 5000 IU/L, and more than 5000 IU/L Results There was no significant difference in age,parity, amenorrhea, location of tubal pregnancy, rupture, pelvic adhesion between group A and group B.Two hundred and seven cases (91.6%, 207/226) were successfully treated at initial laparescopy. One hundred and fifty-two cases got follow up and 55 cases lost follow up at 3 to 6 months after surgery. There was statistical difference in preoperative hCG value which median were 980 (55-12 000) IU/L in group A,3150 (570-40 000) IU/L in group B(P<0.01); the diameter of tubal gestational sac were (3.4±1.3)cm in group A and (5.0±1.7) cm in group B(P<0.01); respectively, the volume of peritoneal bleeding were 200 (0-1500) ml and 300 (0-1600) ml, the rate of live tubal embryo was 2% (2/89) in group A and 11% (9/82) in group B, which all reached statistical difference (P<0. 05). Among 171 cases in both group A and 8, the rate of tubal patency were 65% (67/103) in 103 cases with maximal diameter of tubal gestational sac less than 5 cm and 32% (22/68) in 68 cases with maximal diameter of tubal gestational sac more than 5 cm, which reached statistical difference (P < 0.01). The rate were 72% (73/102) in patients with serum level of hCG less than 2000 IU/L, 29% (12/42)in patients with 2000 IU/L to 5000 IU/L and 15% (4/27)in patients with more than 5000 IU/L, which also showed statistical difference (P <0.05). It was observed that preoperative serum hCG level (OR=0.277, P<0.01), the maximal diameter of gestational sac (OR=0.577, P<0.01) and the volume of peritoneal bleeding (OR=0.999, P < 0.05) were significant factors influencing successful laparoscopy treatment by logistical regression analysis.Conclusion In order to preserve fertility, laparoscopic conservative surgery was a safe and feasible approach in treatment of tubal pregnancy. Preoperative serum hCG levels, size of tube gestational sac were significant factors influencing successful laparoscopic surgery.
