Anterior placental location influences onset and progress of labor and postpartum outcome.

INTRODUCTION: The aim of the study is to evaluate whether placental location at term is associated with delivery outcome. METHODS: A prospective study including 2354 patients with singleton pregnancy at term admitted for vaginal delivery was conducted. Placental position was determined before delivery by ultrasonographic examination performed transabdominally with women in the supine position. Maternal characteristics and delivery outcome such as premature rupture of membranes, induction of labor, mode and gestational age at delivery, indication for cesarean section, duration of the third stage, postpartum hemorrhage (PPH) and manual removal of placenta were correlated with anterior, posterior or fundal placental locations. RESULTS: Among women enrolled: i) 1164 had an anterior placenta, ii) 1087 a posterior placenta, iii) 103 a fundal placenta. Women with anterior placenta showed: i) a higher incidence of induction of labor (p = 0.0001), especially for postdate pregnancies and prolonged prelabor rupture of membranes (p < 0.0001), ii) a higher rate of cesarean section rate for failure to progress in labor (p = 0.02), iii) a prolonged third stage (p = 0.01), iv) a higher incidence of manual removal of placenta (p = 0.003) and a higher rate of PPH in vaginal deliveries (p = 0.02). DISCUSSION: The present study showed the influence of anterior placental location on the course of labor, with a later onset of labor, a higher rate of induction and cesarean section and postpartum complications. The reason for this influence on labor and delivery complications remains to be elucidated.

What kind of surgery for cervical carcinoma?

The incidence and mortality of cervical cancer have changed over the past 50 years in developed countries, but this kind of tumor still remains a significant clinical problem because it is the second most common cause of morbidity and mortality from cancer among women. After histological confirmation of invasive cervical cancer, the extent of disease was determined using clinical criteria to assign a stage. This assessment is important because, while for the other gynecologic cancers clinical information obtained by surgery and histopathological examination is implemented and concurs to define the staging of the disease, the cervical cancer tumor stage is given after the primary diagnosis. In this review we discuss how the surgical approach to cervical cancer has been evolved, in order to modulate the radicality of the intervention itself and thus to preserve the pelvic innervation. This step has been achieved by deepening knowledge of functional pelvic anatomy and modulating the radicality of hysterectomy according to well defined surgical landmarks.
