Closure or nonclosure of the visceral peritoneum at cesarean delivery

Article Abstract:

Leaving the inner abdominal sac open after cesarean deliveries using horizontal incisions may reduce the risk of infection and other postoperative complications. Researchers assigned 549 women with cesarean deliveries to either nonclosure (262 women) or closure (287 women) of the peritoneum. Women whose peritoneums were surgically closed required significantly more antibiotics and experienced fever and cystitis more often than women whose peritoneums were left open. Women in the nonclosure group spent significantly less time in surgery, under general anesthesia, and in the hospital than women in the closure group. Leaving the peritoneum open may reduce the development of adhesions and trauma to peritoneal tissue caused by suturing and suture material.

Oxytocin and vasopressin 1a receptor gene expression in the cycling or pregnant human uterus

Article Abstract:

Cell receptors for oxytocin appear to increase only during the first half of pregnancy. Oxytocin is a hormone produce by the hypothalamus and a similarly named drug is used to induce labor. Researchers measured the number of cell receptors in samples of uterine tissue taken from 95 pregnant women who had a cesarean section between 26 and 42 weeks' gestation and seven women who were having a hysterectomy. The number of cell receptors as measured by messenger RNA was lower in contracting tissue and in patients in advanced labor compared to tissue taken from non-pregnant women.

Combined ultrasonographically guided drainage and laparoscopic excision of a large ovarian cyst

Article Abstract:

Large ovarian cysts may be removed without performing traditional abdominal surgery if they are drained of fluid first. Researchers evaluated a 40-year-old woman with a large ovarian cyst that was equal to the size of a 26-week pregnancy. Because she wanted to preserve her fertility, she did not want an open abdominal procedure. The cyst was removed by first draining it of fluid under ultrasonographic guidance then placing the ovary in a bag through a laparoscopic incision and removing it through an incision in the vagina. No cancer was found.
