A rare case of extraluminal interstitial pregnancy treated with laparoscopic cornuotomy.

We report an extremely rare case of an extraluminal interstitial pregnancy. A 36-year-old nulliparous woman visited our hospital during the fifth week of gestation. Although no intrauterine gestational sac (GS) was identified, transabdominal ultrasonography revealed a GS-like cyst was detected in the right uterine horn. She underwent laparoscopic surgery for a suspected interstitial ectopic pregnancy. After laparoscopic cornuotomy, dye leakage was observed from the fimbria rather than the incision site. Finally, the patient was diagnosed with a right extraluminal interstitial pregnancy. Hysterosalpingography performed at three postoperative months revealed bilateral tubal passage. She conceived 7 months after surgery, with safe delivery by elective cesarean section at 38 weeks.

Significance of gestational weight gain in spontaneous onset of labor at term.

AIM: To investigate the significance of gestational weight gain (GWG) in association with the spontaneous onset of labor at term. METHODS: A retrospective cohort study on 985 pregnant women (629 nullipara and 356 pluripara) who delivered singleton babies at term was conducted. We reviewed the maternal demographics (age, parity, prepregnancy body mass index [BMI]) and the perinatal outcomes (gestational age [GA] and the type [spontaneous or induced] of labor onset, and GWG). The subjects were categorized by prepregnancy BMI and GWG. The rates of spontaneous onset of labor were compared between the nullipara and pluripara groups. Kaplan-Meier survival analysis was applied to evaluate the time to spontaneous labor according to prepregnancy BMI and GWG. A Cox proportional hazards model was used to determine the independent predictive factor for spontaneous onset of labor. RESULTS: In both the nullipara and pluripara group, women with prepregnancy obesity were less likely to enter spontaneous labor. In nullipara, women with excessive weight gain were less likely to enter spontaneous labor. In pluripara, women with poor gain were more likely to enter spontaneous labor. In the multivariate model, GWG was independently associated with the spontaneous onset of labor in both nullipara (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.75-0.98, P = 0.03) and pluripara (HR 0.82, 95% CI 0.64-0.93, P = 0.005). CONCLUSION: Greater maternal weight gain was significantly associated with longer gestation and a decreased likelihood of spontaneous onset of labor at term.
