Surgical treatment of tubal ectopic pregnancy through posterior colpotomy: experience from a Brazilian university hospital

The objective of this study was to evaluate the feasibility of posterior colpotomy for the surgical treatment of tubal ectopic pregnancy in hemodynamically stable women. We performed a retrospective analysis of medical records obtained over a period of 18 months. Twelve cases were identified, with the following characteristics: mean gestational age, 7.7 weeks; mean serum β-human chorionic gonadotropin level, 7,786 mIU/mL; and greater diameter of the mass, 15–69 mm. Treatment was successful in all cases. Salpingectomy was performed in 10 patients (83.3%) and salpingostomy, in 1 patient. The remaining patient only received peritoneal lavage, as the evidence of ectopic abortion with only a slightly dilated uterine tube was found during surgery. The mean surgical time was 42.5 minutes. In the analyzed cases, posterior colpotomy was found to be a feasible alternative method for the surgical treatment of tubal ectopic pregnancy in hemodynamically stable women.

Fetoscopic laser photocoagulation for twin-to-twin transfusion syndrome treatment: initial experience in tertiary reference center in Brazil

OBJECTIVE: To evaluate the initial maternal and perinatal outcomes of fetoscopic laser photocoagulation for the treatment of twin-to-twin transfusion syndrome (TTTS) in a referral center in Brazil. METHODS: This prospective observational study analyzed 24 fetoscopic laser photocoagulation procedures at 18–26 weeks of gestation. TTTS severity was determined using the Quintero classification. Blood vessels that crossed the interamniotic membrane were nonselectively photocoagulated. The χ2 test and Mann-Whitney U test were used for the statistical analysis. RESULTS: The mean (±standard deviation) age of pregnant women, gestational age at surgery, surgical time, gestational age at birth, and newborn weight were 32.2±4.1 years, 20.7±2.9 weeks, 51.8±16.7 minutes, 30.5±4.1 weeks, and 1,531.0±773.1 g, respectively. Using the Quintero classification, there was a higher percentage of cases in stage III (54.2%), followed by stages IV (20.8%), II (16.7%), and I (8.3%). Ten (41.7%) donor fetuses died and 14 (58.3%) donor fetuses survived until the end of gestation. Placental insertion location (anterior vs. posterior) did not affect the incidence of iatrogenic septostomy, surface bleeding, and premature rupture of membranes until the end of gestation. The death rate of donor and recipient fetuses before 24th gestational week increased with severity of TTTS. CONCLUSION: The maternal and perinatal outcomes resulting from the implementation of a new minimally invasive surgical technique are in line with those obtained in major centers worldwide, considering the learning curves and infrastructures.
