Internal herniation (IH) is a common problem after laparoscopic Roux-en-Y gastric bypass surgery (RYGB). Routine closure of the mesenteric defects (MDs) reduces the risk of IH. Only very few articles report on risk factors for IH or describe detailed closing techniques. There is no consensus yet on the best closing method. The objective of this study is to determine the optimal stapling method for closure of MDs after RYGB. All performed RYGB procedures in our high-volume bariatric institute were included. Quality of the closure was scored in the categories poor, sub-optimal, and optimal, to see if the quality of the closure would predict the chance of reopening of the MDs and, therefore, the chance of IH. During any type of laparoscopy in the follow-up of the patient, the conditions of the MDs were stated, for example during diagnostic laparoscopy in symptomatic patients suspicious for IH or during laparoscopic cholecystectomy. Technically well-executed closure of Petersen’s space (PS) with two rows of staples had a greater chance of still being closed upon re-inspection compared to closure with one row (odds ratio = 8.1; 95% confidence interval [1.2–53.2], p= 0.029). Optimal closure of the MD at the jejuno-jejunostomy (JJ-space, JJS) resulted in more closed JJSs upon re-inspection compared to sub-optimal closure (odds ratio = 3.6 [CI 95% 0.8–16.1], p= 0.099). Non-optimally closed MDs had higher reopening rates and, therefore, pose an additional risk for IH. Our classification provides a quality assessment of MD closure during RYGB and gives insight into how to optimize surgical technique.

Risks associated with IVF and related assisted reproduction technologies include complications of ovarian stimulation, surgical procedures and pregnancy itself. Serious complications are uncommon but may be potentially life threatening. The aims of this study were to compare the mortality rates of women who received IVF treatment, as well as those who were referred but were not treated, with the mortality rate in the general female population, to determine the maternal mortality rate following IVF conception and to establish whether any deaths had occurred as a result of treatment complications.

Evaluation of the long-term health of children born using in-vitro fertilization (IVF) provides important information to clinicians and consumers. Until very recently, there have been no published data on the incidence of cancer in children conceived as a result of IVF, despite a number of case reports of neuroblastoma in children conceived using fertility drugs. This study used a record-linkage cohort design to investigate the incidence of cancer in children born after IVF. The study included all conceptions using assisted reproductive technologies between 1979 and 1995 at two clinics in Victoria, Australia that resulted in a live birth. Data on births were linked with a population-based cancer registry to determine the number of cases of cancer that occurred. The standardized incidence ratio (SIR) was calculated by comparing the observed number of cases to the expected number of cases. The final cohort included 5249 births. The median length of follow-up was 3 years, 9 months (range 0-15 years). In all, 4.33 cases of cancer were expected and six were observed, giving a SIR of 1.39 (95% CI 0.62-3.09). This study found that children conceived using IVF and related procedures did not have a significantly increased incidence of cancer in comparison to the general population.

Preterm birth is associated with increased perinatal morbidity and mortality and an elevated risk of disability. Women with precancerous changes of the cervix who have had treatment such as conization or a loop electrosurgical excision procedure (LEEP) are believed to be at increased risk of preterm birth. However, because many of the known risk factors for preterm birth, such as sexually transmitted disease, smoking, or prior induced abortion, also are associated with an increased risk of precancerous changes in the uterine cervix, it has been difficult to determine the degree risk due solely to cervical treatment from the degree of risk due to the other risk factors for preterm birth. This retrospective study was intended to compare rates of preterm birth in women having precancerous cervical changes to those of the general age-standardized population, and to detect any effect of cervical treatment on the time of delivery. Preterm deliveries, defined as those taking place before 37 weeks' gestation, were analyzed in 5548 women referred to a single institution in the years 1982–2000 who had either an abnormal Pap smear or a cervix that appeared abnormal.
