Abstract
Objective To explore the safety and feasibility of blocking blood flow in interstitial tubal pregnancy treated with laparoscopic opening-taking embryo operation. Methods The clinical data of 98 patients with lump interstitial tubal pregnancies (requesting reserve procreate function) from January 2006 to December 2013 were chosen. Among them, 56 patients were in study group (January 2010-December 2013) and 42 patients were in control group (January 2006-December 2009). All patients were treated with opening-taking embryo by laparoscopic operation. In study group, we first blocked the uterine artery and ovarian artery blood supply of pregnancy lump, secondly opened pregnancy lump and stripped gestation sac with hydraulic pressure separation during operation. Whereas, in control group, we opened pregnancy lump and taken out pregnancy tissues according to convention method without blocking blood flow. Operation success rate, operation blood volume, operation time, persistent ectopic pregnancy (PEP) happening rate, fallopian tube unobstructed information, and pregnancy information after operation were compared between two groups. Results In study group, operation success rate was 96.4%, which was significantly higher than that in control group (61.9%) (P<0.01); operation blood volume was[(20.7±10.4)ml], which was significantly less than that in control group [(60.7±18.4)ml](P<0.01); operation time [(46.6±14.2)min] was significantly shorter than that in control group [(66.5±19.4)min](P<0.01); there was no PEP in study group, while there were 5 PEPs (11.9%) in control group. Fallopian tube unobstructed rate after operation in study group (76.9%) was significantly higher than that in control group (41.7%) (P<0.05). Conclusions Application of blocking blood flow in opening-taking embryo by laparoscopic operation on lump interstitial tubal pregnancies is safe and effective.
