[Management of premature rupture of the membranes at term: how long to delay? Results of a prospective multicentric study in 713 cases]. / Rupture prématurée des membranes à terme: quel délai d'expectative? Résults d'une étude prospective multicentrique, à propos de 713 cas.

OBJECTIVE: The aim of our study was to define he best delay for management of spontaneous rupture of the membranes at term. MATERIALS AND METHODS: We conducted a prospective multicentric study in western France defining 3 groups of expectancy (6, 12 and 24 hours) to assess obstetrical, neonatal and maternal outcomes. RESULTS: We included 713 patients. There was no significant difference in neonatal and maternal morbidity between the 3 groups. The rate of cesarean section was statistically higher in the 6-hour group (12%). There was no statistical difference between 12 and 24 hours but the rate was lower in the 12-hour group (5.5 versus 7.9%). CONCLUSION: Based on our findings and a review of the literature, we have decided that in cased of premature rupture of the membranes at term, a 12 hour delay is best. At most two prostaglandin maturations can be performed in unfavorable cervixes.

[Primary retroperitoneal mucinous cystadenoma: a case treated by celioscopic surgery]. / Cystadénome mucineux rétropéritonéal primitif: un cas opéré par coelioscopie.

We used laparoscopy to treat a case of primary retroperitoneal mucinous cystadenoma. This tumours is rarely encountered and has been reported in 22 cases in the literature. The histogenesis is uncertain. Diagnosis is never made preoperatively since primary retroperitoneal mucinous cystadenomas are usually mistaken for cystic lymphangiomas of the retroperitoneum. Surgery is the only treatment. Laparoscopic surgery can be used only if the cystadenocarcinomatous nature of the tumour is ruled out.
