Rates of ongoing pregnancy and live births were higher among women who underwent hysterosalpingography with oil contrast than among women who underwent this procedure with water contrast. (Netherlands Trial Register number, NTR3270 .).

Retained surgical sponges have been reported to occur after a diversity of surgical procedures, but transmural migration is a very unusual sequela. This article reports a case in which a retained surgical sponge eroded from the intra-abdominal space into the intestinal lumen, migrated distally, and spontaneously passed with defecation 12 weeks after the cesarean section. We performed a systematic review of the literature in Pubmed and found 64 cases of transmural migration of retained surgical sponges. Sixty-four cases have been reported of transmural migration, mainly after intra-abdominal surgery. The most frequent site of impaction is the intestine (75%), but we also found 2 cases that describe migration into the stomach and 7 into the bladder. Five more cases have been published describing transdiaphragmic migration. Only 4 cases describe a sponge spontaneously expelled through the rectum, whereas more than 93% needed re-intervention. We strongly advise only the use sponges with radiopaque markers during surgery and additional methodical wound/body cavity examination.

BackgroundA caesarean section (CS) can cause a defect or disruption of the myometrium at the site of the uterine scar, called a niche. In recent years, an association between a niche and postmenstrual spotting after a CS has been demonstrated. Hysteroscopic resection of these niches is thought to reduce spotting and menstrual pain. However, there are no randomised trials assessing the effectiveness of a hysteroscopic niche resection.Methods/DesignWe planned a multicentre randomised trial comparing hysteroscopic niche resection to no intervention. We study women with postmenstrual spotting after a CS and a niche with a residual myometrium of at least 3 mm during sonohysterography. After informed consent is obtained, eligible women will be randomly allocated to hysteroscopic resection of the niche or expectant management for 6 months.The primary outcome is the number of days with postmenstrual spotting during one menstrual cycle 6 months after randomisation. Secondary outcomes are menstrual characteristics, menstruation related pain and experienced discomfort due to spotting or menstrual pain, quality of life, patient satisfaction, sexual function, urological symptoms, medical consultations, medication use, complications, lost productivity and medical costs. Measurements will be performed at baseline and at 3 and 6 months after randomisation. A cost-effectiveness analysis will be performed from a societal perspective at 6 months after randomisation.DiscussionThis trial will provide insight in the (cost)effectiveness of hysteroscopic resection of a niche versus expectant management in women who have postmenstrual spotting and a niche with sufficient residual myometrium to perform a hysteroscopic niche resection.Trial registrationDutch Trial Register NTR3269.

Oligomenorrhoea at age 18 years is better predicted by menstrual cycle pattern at age 15 years than by LH or androgen concentrations or PCO at this age. Not only obese, but also normal weight oligomenorrhoeic, adolescents have a high risk of remaining oligomenorrhoeic.
