Objective:To evaluate the efficacy of Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization in the treatment of tubal obstructive infertility of liver depression and qi stagnation type.Methods:A total of 60 patients with tubal obstructive infertility of liver depression and qi stagnation type who met the inclusion criteria were selected, between August 2018 and June 2020, and they were divided into the observation group with 31 cases and the control group with 29 cases, according to the random number table method. The control group was treated with hysteroscopic recanalization, while the observation group was given Chaichuan Tongren Mixture on the basis of the control group. Both groups were treated for 4 months and followed up for 12 months. TCM syndromes were scored before and after treatment, and prostaglandin E 2 (PGE 2) was detected by fully automatic biochemical analyzer and levels of TNF-α, CRP and IL-6 were measured by ELISA. The tubal patency of patients after treatment was observed, the pregnancy status was recorded after the end of follow-up and the clinical efficacy was evaluated. Results:The total effective rate was 96.77% in the observation group and that in the control group was 75.86% ( χ2=4.01, P<0.01). The scores of breast distending pain, irregular menstruation, dark purple menstrual flow and lumbosacral pain in the observation group after treatment were significantly lower than those in the control group ( t values were 17.69, 21.67, 20.89, 14.67, 18.20, respectively, all Ps<0.001). After treatment, the levels of serum PGE 2, TNF-α, CRP, and IL-6 were significantly lower in the observation group than those in the control group [(65.31±6.73) ng/L vs. (87.10±8.85) ng/L, t=10.78; (6.90±0.71) ng/L vs. (11.35±1.23) ng/L, t=17.30; (2.47±0.25) mg/L vs. (5.10±0.52) mg/L, t=25.23; (12.38±1.26) ng/L vs. (30.16±3.15) ng/L, t=29.05] ( P<0.01). After treatment, there was statistical significance in the total effective rate of tubal patency of 96.8% (30/31) in the observation group compared to 79.3% (23/29) in the control group ( χ2=4.43, P<0.01). At the end of follow-up, the pregnancy rate was 71.0% (22/31) in the observation group and 44.8% (13/29) in the control group, and the difference was statistically significant ( χ2=4.21, P<0.01). Conclusion:The Chaichuan Tongren Mixture supplemented with hysteroscopic recanalization can reduce the levels of inflammatory mediators and increase the pregnancy rate of patients with tubal obstructive infertility of liver depression and qi stagnation type.

Relationship between fallopian tube abnormality and repeated failure of IVF / 中国实用妇科与产科杂志

Interventional therapy for fallopian tube obstructive infertility / 中国实用妇科与产科杂志

Fallopian tube obstruction accounts for30%-50% of female infertility.In patients with com-plete or partial obstruction of the fallopian tube diag-nosed by hysterosalpinography(HSG),after performedby selective salpingography(SSG)and fallopian tuberecanalization(FTR)can not only eliminate the falsepositive results in most of the examinations,but alsodredge the fallopian tube and improve the patency ofthe fallopian tube.This is an important method to treatfallopian tube obstructive infertility.fallopian tube obstructioninfertilityin-

Application of liquid pressurization under obstruction of healthy-side uterine horn with catheter tip combined with guidewire recanalization in treating unilateral obstruction of fallopian tube / 介入放射学杂志

Objective To investigate the clinical application of liquid pressurization under obstruction of healthy-side uterine horn with the tip of double lumen balloon catheter combined with guidewire recanalization in treating unilateral obstruction of fallopian tube.Methods Hysterosalpingography was performed in infertility patients.A total of 50 patients with unilateral obstruction of fallopian tube were selected.Attempt was made to use catheter tip to obstruct the healthy-side uterine horn,then liquid pressurization was carried out to reopen fallopian tube,and the relationship between the success of recanalization and uterine morphology was analyzed;further guidewire recanalization was employed when liquid pressurization method failed,and the recanalization rate was calculated.Results In 33 among the 50 patients,the distance from the uterine horn to the cervical internal orifice was shorter than the catheter length that was inserted into the uterus,besides,the width of the uterine horn was smaller than the catheter diameter,thus the uterine horn was tightly occluded by the catheter tip.Recanalization of the fallopian tube was obtained in 19 patients,and recanalization of the fallopian tube failed in 14 patients because the obstruction was very severe.In 17 among the 50 patients,the distance from the uterine horn to the cervical internal orifice was longer than the catheter length that was inserted into the uterus,besides,the width of the uterine horn was larger than the catheter diameter,thus the uterine horn could not be tightly occluded by the catheter tip,resulting failure of recanalization of fallopian tube.Further guidewire recanalization had to be carried out for the 33 patients whose recanalization of fallopian tube with liquid pressurization method failed,and recanalization of fallopian tube was achieved in 22 patients.Conclusion Liquid pressurization under obstruction of healthy-side uterine horn with the tip of double lumen balloon catheter can reopen the obstructed fallopian tube in some patients,and the success of recanalization is closely related to the uterine morphology.Additional use of guidewire recanalization technique can significantly improve the recanalization rate for unilateral fallopian tube obstruction.

Objective To evaluate the curative effect of fallopian tube perfusion with ozone water in treating obstructed fallopian tube in pluripara.Methods A total of 116 patients with distal fallopian tube obstruction were included in this study.The diagnosis was confirmed by clinical and laboratory materials.The patients were randomly divided into the study group and the control group with 58 patients in each group.During hospitalization period all patients received interventional recanalization therapy for obstructed fallopian tube.For the patients of the study group,ozone water perfusion of fallopian tube was employed,while for the patients of the control group,fallopian tube perfusion with conventional anti-inflammatory drug and antiadhesion solution was adopted.All the patients were followed up for 6 months,the pregnancy rate and the fallopian tube re-occlusion rate of both groups were calculated,and 2 weeks after the treatment the patients'discomfort symptoms were evaluated.Results The success rate of fallopian tube recanalization,the pregnancy rate and the re-obstruction rate in the study group were 93.1％ (54/58),79.3％ (46/58) and 5.2％(3/58) respectively,which in the control group were 91.4％ (53/58),60.3％ (35/58) and 172％ (10/58) respectively.Statistical analysis indicated that no significant difference in the success rate of fallopian tube recanalization existed between the two groups (P＞0.05).The pregnancy rate of the study group was higher than that of the control group,while the re-obstruction rate in the study group was lower than that in the control group;the differences between the two groups were statistically significant (P＜0.05).No significant differences in discomfort symptom scores existed between the two groups (P＞0.05).Conclusion Fallopian tube perfusion with ozone water can be adopted for tubal recanalization,this technique can effectively improve the postoperative pregnancy rate and reduce the tubal re-obstruction rate.

The affects of placement of intrauterine device on the incidence of fallopian tube obstruction / 天津医药

Objective To investigate whether the placement of intrauterine device (IUD) can increase the incidence of fallopian tube obstruction. Methods A total of 458 patients with secondary infertility who visited the outpatient clinic between January 2014 and December 2015 were selected for observation group, of which, 246 cases who used IUD in the past but were not pregnant were the IUD group, and 212 cases with no history of using IUD were the control group. According to the medical history of two groups,and based on test results of gynecological routine inspection, mycoplasma (UU), chlamydia (CT), type B ultrasound examination of pelvic cavity and hysterosalpingography (HSG) in two groups, whether the placement of IUD increased the risk of fallopian tube obstructive infertility was comprehensively analyzed. Results There was a higher incidence of reproduction tract infection in patients with fallopian tube obstruction than that in patients without fallopian tube obstruction in IUD group (pelvic infection 32.6% vs. 15.7%,CT 23.9% vs. 9.3%,UU 42.8% vs. 18.5%, vaginitis 36.2%vs. 24.1%,P0.05). There were no significant differences in history of uterine cavity operations and incidence of reproductive tract infection between two groups of patients with tubal obstruction(uterine cavity operations 55.8%vs. 45.2%,pelvic infection 32.6%vs. 39.3%,vaginitis 36.2% vs. 34.1%, CT 23.9% vs. 27.4%,UU 42.8% vs. 40.7%,P>0.05). Conclusion There is no necessary correlation between fallopian tube obstruction and placement of IUD, which therefore will not increase the incidence of fallopian tube obstruction.

Objective To explore the clinical value of therapeutic alliances of oviduct recanalization and video-laparoscope in the treatment of infertilitas feminis caused by multiple salpingemphraxis. Methods Sixty-seven patients with salpingemphraxis in 127 oviducts complicated with adhesions in fimbriated extremities were enrolled into our study. All the patients underwent separation of adherences in fimbriated extremities and neostomy using a video-laparoscope 2 to 3 days after selective oviduct recanalization. The therapeutic effects were retrospectively reviewed focusing on recanalization rate of proximal three segments, complete recanalization rate, and pregnancy rate and relevant complications during the follow-up period were analyzed. And patients with infertilitas feminis in the follow-up period underwent repeated salpingography to determine whether oviduct was repeatedly obstructed. Results The therapeutic alliance of oviduct recanalization and video-laparoscope were performed successfully in this cohort. Owing to the treatment of oviduct recanalization, recanalization rate of proximal three segments was 97.6% oviducts (124/127). Due to the alliance of oviduct recanalization and video-laparoscope, complete rate of oviduct were 98.4% (122/124). One year after operation, the pregnancy rate, ectopic pregnancy rate, and non pregnancy rate were 58.2% (39/67), 4.5% (3/67), and 37.3% (25/67), respectively. The patients with non pregnancy were composed by repeated oviduct obstruction in 25.4% (17/67) and non obstruction in 11.9% (8/67). Conclusion Therapeutic alliances of oviduct recanalization and video-laparoscope could be an effective method for the treatment of infertilitas feminis caused by multiple salpingemphraxis, and be helpful for the enhancement of pregnancy rate.
