The pregnant women at higher risk of preterm labor, referred to the perinatal clinic of Kosar University Hospital in Urmia district of Iran, were enrolled into a parallel randomized clinical trial. In the investigational arm of the clinical trial, a double cervical cerclage procedure was performed addition to McDonald cerclage. In the control group however, only McDonald cerclage was performed. Extreme preterm labor (GA < 33 weeks) was the primary endpoint of this clinical trial. Age, gestational age at cerclage time, and gravidity were not found to be statistically different between the groups. Means of gestational age were 37.4 and 36.2 weeks, respectively, for the investigational and control groups. The gestational age was 1.2 weeks longer for double cerclage group but the difference was not found to be statistically significant. Preterm birth before 33 weeks of gestation was not experienced by any of the patients who received double cerclage, but five women in control group developed such an extreme preterm labor (P < 0.05). The absolute risk reduction in using double cerclage over traditional method was 18 percent (95% confidence interval, 4%–32%). Double cerclage appeared to have higher efficacy than traditional cerclage in preventing preterm labor <33 weeks of gestation.

Background: Few cases with fistulous communication between the GI system and female adnexal structure have been reported in the literature, and bilateral contrast spillage has been reported only in one case, and this case is the second one all over the world. Case Presentation: The case was a 27-year-old woman with a diagnosis of primary infertility. She was booked with hysterosalpingogram (HSG) as part of the routine workup in the infertility clinic. There was a positive history of pelvic surgery for bilateral adnexal cysts for her in 2014. In this case, previous pelvic surgery without any medical problems was the strongest risk factor for tubo-intestinal fistula. Cystectomy performed for the left adnexal cyst and the right adnexal cyst was only drained. The pathologic report for the left ovarian cyst was endometriosis. HSG result showed evidence of bilateral fallopian tube opacification with contrast outlining from the fallopian tubes. Contrast leakage happened to the adjacent small intestine in the right side and peritoneal cavity on the left side. Conclusion: Fistulous connections between fallopian tube and intestine will remain an exceptional rarity. The reported case could be a good lesson illustrating that the adherence to general surgical principles (meticulous hemostasis, careful applying of diathermy, etc.) and a watchful postoperative care could protect the patient from both usual and unusual complications.
