Fundal pressure in second stage of labor (Kristeller maneuver) is associated with increased risk of levator ani muscle avulsion.

OBJECTIVE: To investigate the association between application of fundal pressure during the second stage of labor (Kristeller maneuver) and the risk of levator ani muscle (LAM) injury. METHODS: This was a prospective case-control study of women recruited immediately after their first vaginal delivery in our university hospital between March 2014 and September 2016. Women who underwent the Kristeller maneuver were recruited as cases. For each case, a control (no Kristeller) was recruited matched for body mass index, use of epidural analgesia, duration of second stage of labor and birth weight. All women were invited to undergo four-dimensional (4D) transperineal ultrasound (TPU) 3-6 months postpartum. The main outcome measure was the presence of LAM avulsion on 4D-TPU. TPU results were compared between cases and controls. Multivariate logistic regression analysis was performed to identify independent risk factors for LAM avulsion. RESULTS: During the study period, 134 women in the Kristeller maneuver group and 128 women in the control group underwent TPU assessment. Women who underwent the Kristeller maneuver had a higher prevalence of LAM avulsion than did controls (38/134 (28.4%) vs 18/128 (14.1%); P = 0.005). In addition, women in the Kristeller-maneuver group had a larger hiatal area on maximum Valsalva maneuver and a greater increase in hiatal area from rest to maximum Valsalva. On multivariate logistic regression analysis, use of the Kristeller maneuver was the only independent factor associated with LAM avulsion (odds ratio, 2.5 (95% CI, 1.29-4.51)). CONCLUSION: The Kristeller maneuver is associated with an increased risk of LAM avulsion when applied in women during their first vaginal delivery. This should be taken into account when deciding to use fundal pressure to accelerate the second stage of labor and when counseling women following childbirth. Copyright © 2018 ISUOG.

Calcium metabolism, vitamin D and bone mineral density after bariatric surgery.

SUMMARY: Lower bone mineral density, vitamin D deficiency, lower lean body mass, greater loss of excess weight, and increased bone turnover are complications found after bariatric surgery correlated in the literature with increased risk of fractures. The prevention and treatment of such complications should begin immediately after surgery. INTRODUCTION: The aims of the study were to evaluate bone mass in patients undergoing bariatric surgery by the Wittgrove technique after 1 year of the procedure and correlate it with body composition, weight loss, 25OH vitamin D levels, and markers of bone metabolism. METHODS: The operated group (OG) participated in a clinical consultation; a blood sample taken and a body composition; and bone mineral density assessment by dual energy X-ray absorptiometry (DXA). The results were compared with a control group (CG). RESULTS: Fifty-six subjects in the OG and 27 in the CG were included. The bone mineral density (BMD), after the surgery, at the lumbar spine (LS) was lower in the OG than in the CG. There was a positive correlation between total body (TB) BMD with 25OHD, body mass index (BMI), and lean mass and an inverse correlation with percentage of excess weight loss (%EWL). Vitamin D deficiency was seen in 60.41% (OG) and in 16.6% (CG). PTH was higher in the OG, with secondary hyperparathyroidism in 41.7%. In 26.5% and 14.2% of the OG, ALP and OC levels were above the reference values. In <50 years, elevated values of carboxy-terminal telopeptide (CTX) were found in 66.7% of patients. A difference was observed in the variation of CTX between 12 and 18 months when compared to over 24 months. CONCLUSIONS: Lower BMD was observed, correlated with lower lean body mass and greater loss of excess weight. Vitamin D deficiency with high prevalence of secondary hyperparathyroidism and high bone turnover was detected. The prevention of bone loss should be initiated in the first months after surgery, which is a period associated with severe muscle loss and increased bone turnover.

Use of a preventive sling surgery for the simultaneous correction of latent stress urinary incontinence during the cystocele repair: two year follow-up.

AIM: The aim of this paper was to assess the feasibility and utility of adding a preventive trans obturatory tape (TOT) during the same intervention for anterior prolapse repair, in patients with masked urinary incontinence and massive cystocele. METHODS: A retrospective trial was conducted in a Tertiary care University Hospital. Ninety-nine women with a massive cystocele (Ba ≥2 cm of pelvic organ prolapse quantification) and an occult stress urinary incontinence were recruited from 2004 to 2010: 53 women were subjected to an anterior fascial reconstruction alone while 46 underwent the same intervention with the addition of TOT. Patients were also asked to rate their overall quality of life, using the International Consultation on Incontinence Modular Questionnaire-Lower Urinary Tract Symptoms Quality Of Life (ICIQ-LUTSqol). All patients were assessed at one, six, twelve and twenty-four months of follow-up. Statistical analysis was performed with SPSS 15.0 software; SPSS inc., Chicago IL, USA was performed using the Chi-square test with Fisher's post-hoc correction. RESULTS: At 24 month follow-up the rate of appearance of stress urinary incontinence at the urogynecological examination, was higher in the group without TOT (81% vs. 19%, P=0.004). In terms of overall quality of life, significantly higher rates of satisfaction have been reported by the group treated with additional TOT (P=0.006). CONCLUSION: The addition of TOT during the anterior prolapse correction seems to give a greater durability to the correction, resulting, in the long term, in a lower rate of urinary symptoms onset (first latency) and in a better quality of life compared to the traditional anterior colporrhaphy alone.
