A prospective study on indwelling suture in preventing re-adhesion of fallopian tube after interventional recanalization

Abstract

Objective To explore the clinical efficacy of indwelling suture in preventing re-adhesion of fallopian tube after fallopian tube recanalization(FTR). Methods Screen 93 patients with fallopian tube obstruction and FTR indications of prospective, the patients without other interference factors of infertility, they were randomized with random sampling into two groups (treatment group 50 and control group 43)and treated by FTR,then the treatment group with indwelling sutures in fallopian tube for 3 days, the control group were infused lipiodol into the tube and with a intrauterine cavity perfusion in 3 days. The two groups received followed up examination at 2,6 months after operation (a treatment was repeated with the case of re-obstruction). Follow-up for 12 months to appraise the pregnancy rate and the influence of pregnancy competence of tube with indwelling suture(6 months after operation, to collect and compare the pregnancy rate and ectopic pregnancy rate of patent tube in two groups). Results The tubal patency rate were 89.8% (53/59) ,89.5% (51/57) of treatment group at 2, 6 months after operation and the control group were75.9% (44/58) ,75.0% (39/52) , there was a significant difference between the two groups (2 m:χ2=4.027, P 0.05). Conclusions The indwelling suture of fallopian tube can prevent re-adhesion better after FTR, then improve the long-term recanalization rate and the pregnancy rate. There is no change on the pregnancy competence of fallopian tube. Key words: Fallopian tube diseases; Radiology,interventional; Treatment outcome
