Surgical repair of an obstetric cloaca with review of the literature.

A complete perineal wound breakdown of a fourth degree laceration leading to a cloaca is a rare but devastating complication of vaginal childbirth. A 32-year-old primiparous woman presented with an obstetric cloaca 4 months following delivery. She underwent preoperative evaluation and, following extensive counselling, elected to proceed with operative repair. The procedure is presented in 15 well-defined steps with photos. The repair was performed in standard fashion with three supplementary steps. These included: (1) division of the rectovaginal tissue into three distinct layers; (2) attachment of these layers individually to the reconstructed perineal body and sphincter and (3) incorporation of the levator muscles into the repair. The wound healed well within 6 weeks of repair. Now 3½ years postoperatively, the patient has no faecal incontinence or sexual dysfunction and only minimal defecatory dysfunction. The discussion describes our surgical approach in the context of a review of the literature.

Clinical Features and Associations of Descending Perineum Syndrome in 300 Adults with Constipation in Gastroenterology Referral Practice.

BACKGROUND: Outlet obstruction constipation accounts for about 30% of chronic constipation (CC) cases in a referral practice. AIMS: To assess the proportion of patients with CC diagnosed with descending perineum syndrome (DPS) by a single gastroenterologist and to compare clinical, radiological, and associated features in DPS compared to patients with constipation. METHODS: We conducted a review of records of 300 consecutive patients evaluated for constipation by a single gastroenterologist from 2007 to 2019, including medical, surgical, and obstetrics history, digital rectal examination, anorectal manometry, defecation proctography (available in 15/23 with DPS), treatment, and follow-up. DPS was defined as > 3 cm descent of anorectal junction on imaging or estimated perineal descent on rectal examination. Logistic regression with univariate and multivariate analysis compared factors associated with DPS to non-DPS patients. RESULTS: Twenty-three out of 300 (7.7%, all female) patients had DPS; these patients were older, had more births [including more vaginal deliveries (84.2% vs. 31.2% in non-DPS, p < 0.001)], more instrumental or traumatic vaginal deliveries, more hysterectomies, more rectoceles on proctography (86.7% vs. 28.6% non-DPS, p = 0.014), lower squeeze anal sphincter pressures (p < 0.001), and lower rectal sensation (p = 0.075) than non-DPS. On univariate logistic regression, history of vaginal delivery, hysterectomy, and Ehlers-Danlos syndrome increased the odds of developing DPS. Vaginal delivery was confirmed as a risk factor on multivariate analysis. CONCLUSIONS: DPS accounts for almost 10% of tertiary referral patients presenting with constipation. DPS is associated with age, female gender, and number of vaginal (especially traumatic) deliveries.

The effect of pregnancy and delivery on anal function in black Africans and Indians.

BACKGROUND: Occult anal sphincter disruption, following childbirth may contribute to the development of anal incontinence (AI). The type and mechanism of injury may differ between first and subsequent deliveries. OBJECTIVES: To describe the effect of pregnancy and delivery on the endosonographic morphology of the anal sphincter and on anal sphincter pressures, and to highlight any differences in these between nulliparous and multiparous Black African and Indian women. METHOD: One hundred Black African and Indian women delivering at two hospitals in the Pietermaritzburg area underwent anal endosonography and manometry in the third trimester of pregnancy and 24 hours post-delivery. Those with occult injury were followed up at 6 weeks and six months. Participants were asked about bowel symptoms at each visit. Ante-natal and intra-partum obstetric data was also recorded. RESULTS: The majority were Black African (82%), and 76% were multiparous. Symptoms of urgency increased from 9% antenatally to 14.6% post-delivery, decreasing to 8.3% at six months. Symptoms of AI increased from 10% antenatally to 12.5% post-delivery, falling to 3.1% at six months. Internal sphincter defects were more common among primiparous and multiparous women delivering vaginally. There was a significant drop in functional anal length post-delivery, irrespective of the mode of delivery. Anal pressures also fell post-delivery and at six weeks post-partum. However, by six months there appeared to be a return to pregnancy values. CONCLUSION: Occult anal sphincter injuries and reduced anal pressures occur after delivery, in the absence of clinically detected anal sphincter trauma, irrespective of the mode of delivery.

Increasing Age Is a Risk Factor for Decreased Postpartum Pelvic Floor Strength.

OBJECTIVES: This study aimed to determine factors associated with decreased pelvic floor strength (PFS) after the first vaginal delivery (VD) in a cohort of low-risk women. METHODS: This is a secondary analysis of a prospective study examining the risk of pelvic floor injury in a cohort of primiparous women. All recruited participants underwent an examination, three-dimensional ultrasound and measurement of PFS in the third trimester and repeated at 4 weeks to 6 months postpartum using a perineometer. RESULTS: There were 84 women recruited for the study, and 70 completed the postpartum assessment. Average age was 28.4 years (standard deviation, 4.8). There were 46 (66%) subjects with a VD and 24 (34%) with a cesarean delivery who labored. Decreased PFS was observed more frequently in the VD group compared with the cesarean delivery group (68% vs 42%, P = 0.03).In modified Poisson regression models controlling for mode of delivery and time of postpartum assessment, women who were aged 25 to 29 years (risk ratio = 2.80, 95% confidence interval, 1.03-7.57) and 30 years and older (risk ratio = 2.53, 95% confidence interval, 0.93-6.86) were over 2.5 times more likely to have decreased postpartum PFS compared with women younger than 25 years. CONCLUSIONS: In this population, women aged 25 years and older were more than twice as likely to have a decrease in postpartum PFS.

[ALLEN-MASTERS SYNDROME AS A CAUSE FOR CHRONIC PELVIC PAIN: DIAGNOSIS, TREATMENT AND LONG TERM FOLLOW-UP].

Chronic pelvic pain is one of the main causes for repeated ambulatory and hospital visits. The main findings on exploratory laparoscopy performed for these complaints are endometriosis and adhesions, while in more than 50% of cases, no cause for the pain is found. In 1955, Allen and Masters reported pain associated with traumatic labor. They reported retroverted and hyper-mobile uterus in all women and during operation, tears in the posterior serosa of the broad igament. A few therapeutic options have been discussed, including repair of the tears, but without long term follow-up and significant relief of symptoms. Tightening of the utero-sacral ligaments following peritoneal resection of the Douglas as a long effective treatment was initially suggested in France in 1972. In 1997, von Theobald showed that it could be conducted by laparoscopy with long term follow-up. We report 3 cases of women diagnosed with Allen-Masters Syndrome, the surgical treatment performed and the long follow-up of these patients. We also discuss the ways to diagnose the syndrome and the preferred modality of treatment.

[Cesarean section and eye disorders]. / Ciecie cesarskie a zaburzenia zwiazane z narzadem wzroku.

Recently, a growing tendency for cesarean birth has been noted both, in Poland and worldwide. Non-obstetric problems constitute a large part of indications for cesarean section. Many ophthalmologists and obstetricians still believe that high myopia, the presence of peripheral retinal degenerations, history of retinal detachment surgery, diabetic retinopathy, or glaucoma are indications for surgical termination of pregnancy. However, these recommendations are not evidence-based. The literature offers no proof that high myopia and previous retinal surgery increase the risk of retinal detachment during spontaneous vaginal delivery. There is only one indication for cesarean section in myopic patients, i.e. the presence of choroidal neovascularization, which can cause subretinal bleeding with acute visual loss. Prolonged and intensified Valsalva maneuver during labor in patients with an active proliferative diabetic retinopathy may be an indication for an elective cesarean section. Uterine contractions during the second stage of vaginal delivery lead to a marked elevation of intraocular pressure. Intraocular pressure fluctuations during the delivery may damage retinal ganglion cells, resulting in further progression of visual field. Thus, glaucoma associated with advanced visual field changes is the next ophthalmic indication for cesarean section. The report presents the current state of knowledge concerning the effect of pregnancy on pre-existing ocular disorders and the influence of physiological changes on the clinical course of these diseases during the stages of natural delivery. The authors discuss also the ophthalmic indications for cesarean section.

Breakdown of Perineal Laceration Repair After Vaginal Delivery: A Case-Control Study.

OBJECTIVE: The aim of the study was to estimate risk factors associated with breakdown of perineal laceration repair after vaginal delivery. METHODS: This is a case-control study of women who sustained a breakdown of perineal laceration repair after vaginal delivery between 2002 and 2015. Cases were patients who sustained a perineal wound breakdown after vaginal delivery and repair of a second-, third-, or fourth-degree laceration. Controls, matched 1:1, were patients who either sustained a second-, third-, or fourth-degree perineal laceration and repair without evidence of breakdown and who delivered on the same day and institution as the case. RESULTS: A total of 104,301 deliveries were assessed for breakdown of perineal laceration. One hundred forty-four met the inclusion criteria. These were matched with 144 controls. Logistic regression analysis demonstrated that smoking is associated with increased risk for breakdown of perineal laceration (adjusted odds ratio [adj. OR], 6.4; 95% confidence interval [CI], 1.2-38.5), whereas a previous vaginal delivery is protective (adj. OR, 0.14; 95% CI, 0.05-0.3). In addition, third- or fourth-degree laceration (adj. OR, 4.0; 95% CI, 1.1-15.7), presence of episiotomy at time of delivery (adj. OR, 11.1; 95% CI, 2.9-48.8), operative delivery (adj. OR, 3.4; 95% CI, 1.2-10.3), midwife performing the laceration repair (adj. OR, 4.7; 95% CI, 1.5-15.8), and use of chromic suture (adj. OR, 3.9; 95% CI, 1.6-9.8) were independent risk factors for breakdown of perineal laceration. CONCLUSIONS: Smoking, nulliparity, episiotomy, operative delivery, third- or fourth-degree laceration, repair by a midwife, and use of chromic suture are independent risk factors for breakdown of perineal laceration repair after vaginal delivery.

Obstetrical complications and Apgar score in subjects at risk of psychosis.

The objective of the study was to identify associations between a history of obstetrical complications (OCs) and the future development of symptoms indicating risk of psychosis (At Risk Mental State - ARMS). The frequency of OCs was assessed in 66 ARMS subjects, 50 subjects with the first episode of schizophrenia (FES) and 50 healthy controls. Obstetrical data was obtained from medical documentation and evaluated with the Lewis and Murray Scale. Definite OCs, according to the Lewis and Murray Scale, occurred significantly more frequently in the ARMS group compared to the controls (χ(2) = 7.79, p = 0.005; OR = 4.20, 95% CI = 1.46-12.11), as well as in the FES subjects compared to the controls (χ(2) = 8.39, p = 0.004; OR = 4.64, 95% CI = 1.56-13.20). Apgar scores in the first (Apgar 1) and the fifth minute after birth (Apgar 5) were significantly lower in the FES subjects compared to the controls (for Apgar 1 score Z = 4.439, p < 0.0001; for Apgar 5 score Z = 5.250, p < 0.0001). The ARMS subjects demonstrated significantly lower Apgar 5 scores compared to the healthy controls (Z = 3.458, p = 0.0016). The results indicate that OCs and low Apgar 5 score should be considered important factors in identifying subjects at risk of developing psychosis.

Profiles and experiences of women undergoing genital fistula repair: findings from five countries.

This article presents data from 1354 women from five countries who participated in a prospective cohort study conducted between 2007 and 2010. Women undergoing surgery for fistula repair were interviewed at the time of admission, discharge, and at a 3-month follow-up visit. While women's experiences differed across countries, a similar picture emerges across countries: women married young, most were married at the time of admission, had little education, and for many, the fistula occurred after the first pregnancy. Median age at the time of fistula occurrence was 20.0 years (interquartile range 17.3-26.8). Half of the women attended some antenatal care (ANC); among those who attended ANC, less than 50% recalled being told about signs of pregnancy complications. At follow-up, most women (even those who were not dry) reported improvements in many aspects of social life, however, reported improvements varied by repair outcome. Prevention and treatment programmes need to recognise the supportive role that husbands, partners, and families play as women prepare for safe delivery. Effective treatment and support programmes are needed for women who remain incontinent after surgery.

Overcoming phase 1 delays: the critical component of obstetric fistula prevention programs in resource-poor countries.

BACKGROUND: An obstetric fistula is a traumatic childbirth injury that occurs when labor is obstructed and delivery is delayed. Prolonged obstructed labor leads to the destruction of the tissues that normally separate the bladder from the vagina and creates a passageway (fistula) through which urine leaks continuously. Women with a fistula become social outcasts. Universal high-quality maternity care has eliminated the obstetric fistula in wealthy countries, but millions of women in resource-poor nations still experience prolonged labor and tens of thousands of new fistula sufferers are added to the millions of pre-existing cases each year. This article discusses fistula prevention in developing countries, focusing on the factors which delay treatment of prolonged labor. DISCUSSION: Obstetric fistulas can be prevented through contraception, avoiding obstructed labor, or improving outcomes for women who develop obstructed labor. Contraception is of little use to women who are already pregnant and there is no reliable screening test to predict obstruction in advance of labor. Improving the outcome of obstructed labor depends on prompt diagnosis and timely intervention (usually by cesarean section). Because obstetric fistulas are caused by tissue compression, the time interval from obstruction to delivery is critical. This time interval is often extended by delays in deciding to seek care, delays in arriving at a hospital, and delays in accessing treatment after arrival. Communities can reasonably demand that governments and healthcare institutions improve the second (transportation) and third (treatment) phases of delay. Initial delays in seeking hospital care are caused by failure to recognize that labor is prolonged, confusion concerning what should be done (often the result of competing therapeutic pathways), lack of women's agency, unfamiliarity with and fear of hospitals and the treatments they offer (especially surgery), and economic constraints on access to care. SUMMARY: Women in resource-poor countries will use institutional obstetric care when the services provided are valued more than the competing choices offered by a pluralistic medical system. The key to obstetric fistula prevention is competent obstetrical care delivered respectfully, promptly, and at affordable cost. The utilization of these services is driven largely by trust.

Distócia de ombro / Shoulder dystocia

A Distócia de Ombro é definida, de acordo com os Colégios Americano e Britânico de Obstetrícia e Ginecologia, como parto que necessita de manobras obstétricas adicionais, após falência da tração da cabeça fetal para liberar os ombros. Apesar de sua baixa incidência, é uma complicação com importante morbidade para o recém nascido e que pode levar a intercorrências maternas, sendo entretanto passível de ser evitada. Esse artigo de revisão se propõe a sumarizar a epidemiologia, fisiopatologia, conduta e complicações, enfocando os fatores de risco e as manobras mais utilizadas, dada a importância de ambos na prevenção dessa complicação. (AU)

The Shoulder Dystocia is defined, according to British and American Colleges of Obstetrics and Gynecology, as delivery which requires additional obstetric maneuvers after failure of traction of the fetal head to release the shoulders. Despite its low incidence, it is a complication with significant morbidity for the newborn and wich can lead to maternal complications. Despite of this, is able to be avoided. This review aims to summarize the epidemiology, pathophysiology, management and complications, focusing on risk factors and the most commonly used maneuvers, due to the importance of both in preventing this complication.

Uterine compression sutures for postpartum hemorrhage: is routine postoperative cavity evaluation needed?

Postpartum hemorrhage due to uterine atony continues to be one of the major causes of maternal morbidity and mortality. Several uterine compression suture techniques have been described and are increasingly being used worldwide as a conservative approach. However, little is known about the long-term effects on the uterine cavity, as well as fertility and pregnancy outcomes. We reviewed the reported complications and uterine findings after the use of compression sutures, both in examinations to evaluate the cavity (hysteroscopy, hysterosalpingography or sonohysterography) and at cesarean section, in order to assess the possible usefulness of routine postoperative cavity evaluation. Overall, the use of uterine compression sutures is effective and safe; however, some severe and potentially life-threatening complications have been reported and could possibly have been prevented if uterine cavity evaluation had been performed. Routine follow-up, both by hysteroscopy and an imaging technique, seems worthwhile.

Prevalence of pelvic floor disorders in the female population and the impact of age, mode of delivery, and parity.

PURPOSE: Dysfunction of pelvic floor may cause many different symptoms, such as urinary and anal incontinence, obstructed defecation and constipation. No previous studies have examined all of these symptoms together. The purposes of the present study were to determine prevalence of pelvic floor disorders among the female population and to evaluate the impact of age, parity, and mode of delivery on these disorders. METHODS: The study was performed on a general population of Turkish women. Women were excluded who were pregnant, who were within 6 months postpartum, who had cognitive disorders or neurological diseases, and who had a history of previous gastrointestinal, anorectal, or gynecological surgery. A questionnaire about urinary incontinence, anal incontinence, constipation, and obstructed defecation along with an extensive obstetric history was administered to 4002 women in face-to-face interviews. All symptoms were defined according to the standard terminology. RESULTS: The median age of the participants was 41 years (range, 15-86). Of the women interviewed, 1067 had no deliveries, 434 women delivered by cesarean only, and 2501 women had one or more vaginal deliveries. Five hundred thirty women had delivered one child, 1880 women had delivered 2 to 3 children, and 582 women had delivered ≥4 children. Overall, 67.5% of women experienced pelvic floor dysfunction of at least one major type. The prevalence of each pelvic floor disorder evaluated in this study was as follows: anal incontinence, 19.8%; urinary incontinence, 50.7%; constipation, 33.2%; and obstructed defecation, 26.8%. Analysis of risk factors demonstrated that age was the major factor associated with the development of pelvic floor dysfunction. Vaginal delivery and higher parity increased the risk of both urinary and defecatory symptoms of pelvic floor dysfunction. CONCLUSION: The study data demonstrate that pelvic floor dysfunction is a common problem among women and it is strongly linked to childbirth and aging.

Expression of monocyte chemotactic protein 3 following simulated birth trauma in a murine model of obesity.

OBJECTIVE: To determine the effect of obesity on simulated birth trauma in leptin-deficient obese mice as measured by relative monocyte chemotactic protein 3 (MCP-3) expression. MATERIALS AND METHODS: A total of 25 wild-type and 25 obese C57BL/6 virgin female mice underwent 1 hour of vaginal distension (VD), sham VD, or anesthesia without VD. Pelvic organ tissues were then harvested either immediately or 24-hours post VD and subsequent real-time polymerase chain reaction analysis was performed. RESULTS: Urethral MCP-3 levels in wild-type mice were elevated from baseline at 0 hours with a return to baseline at 24 hours in both VD and sham VD groups. In obese mice, there was a 6-fold elevation in MCP-3 levels at 0 hours after sham VD vs control (P <.05), which then returned to baseline levels at 24 hours. After undergoing VD, MCP-3 levels increased to 6-fold baseline values (P = .002) at 0 hours, with continued elevation in MCP-3 levels to 15 times control levels (P = .0003) at 24 hours. CONCLUSIONS: MCP-3 is significantly over-expressed in the urethral tissues of both wild-type and obese mice immediately after any urethral manipulation. At 24 hours, the MCP-3 expression patterns become divergent between VD and sham VD in obese mice. With a greater degree of trauma, MCP-3 continued to rise at 24 hours, suggesting that the underlying obesity resulted in alterations in response to tissue injury, paralleling the degree of injury. Such associations warrant further investigation into the role of MCP-3 as a chemokine for stem cell migration, with implications for subsequent tissue repair mechanisms after birth trauma.

Perineal reconstruction with bilateral bilobed flap for cloacal-like defect after childbirth.

Fourth degree lacerations of the vaginal wall and perineum following childbirth can cause cloacal-like defects of the perineum. The loss of the anterior anal sphincter and resultant thinning of the perineum and rectovaginal septum can lead to fecal incontinence and difficulties with sexual activity. This article introduces a technique to combine repair of the anterior anal sphincter with reconstruction of the perineal body with bilateral pedicled bilobed flaps.

[The basis of rehabilitation and treatment in acute period of perinatal cerebral pathology].

We have examined 89 newborns with perinatal CNS lesions due to critical states at birth. Disturbances of vital functions of the organism developed as a result of severe posthypoxia states at birth that exert a significant effect on patient's quality of life in the following age periods, including the formation of "rough" polyorganic injuries, have been studied. Therefore, the adequate treatment of post-critical states in the neonatal period demands understanding of pathogenetic mechanisms of their development that has formed the basis for using peptide drugs with neuroprotective effect, in particular, cortexin.

Treatment of stress urinary incontinence with adipose tissue-derived stem cells.

BACKGROUND AIMS: Effective treatment for stress urinary incontinence (SUI) is lacking. This study investigated whether transplantation of adipose tissue-derived stem cells (ADSC) can treat SUI in a rat model. METHODS: Rats were induced to develop SUI by postpartum vaginal balloon dilation and bilateral ovariectomy. ADSC were isolated from the peri-ovary fat, examined for stem cell properties, and labeled with thymidine analog BrdU or EdU. Ten rats received urethral injection of saline as a control. Twelve rats received urethral injection of EdU-labeled ADSC and six rats received intravenous injection of BrdU-labeled ADSC through the tail vein. Four weeks later, urinary voiding function was assessed by conscious cystometry. The rats were then killed and their urethras harvested for tracking of ADSC and quantification of elastin, collagen and smooth muscle contents. RESULTS: Cystometric analysis showed that eight out 10 rats in the control group had abnormal voiding, whereas four of 12 (33.3%) and two of six (33.3%) rats in the urethra-ADSC and tail vein-ADSC groups, respectively, had abnormal voiding. Histologic analysis showed that the ADSC-treated groups had significantly higher elastin content than the control group and, within the ADSC-treated groups, rats with normal voiding pattern also had significantly higher elastin content than rats with voiding dysfunction. ADSC-treated normal-voiding rats had significantly higher smooth muscle content than control or ADSC-treated rats with voiding dysfunction. CONCLUSIONS: Transplantation of ADSC via urethral or intravenous injection is effective in the treatment and/or prevention of SUI in a pre-clinical setting.

Maternal obesity, health status during pregnancy, and breastfeeding initiation and duration.

OBJECTIVE: The purpose of this study was to determine whether maternal prepregnancy overweight/obesity has independent effects on breastfeeding initiation and duration and whether these effects are different for women who experience medical problems during pregnancy or labor/delivery complications in comparison with those who have no medical or labor/delivery complications. METHODS: We used the early childhood longitudinal study-birth cohort data. Kaplan-Meier survival functions, logistic, and Cox regression modeling were used in the analyses. RESULTS: Findings indicate that overweight/obese women with medical or labor/delivery complications were less likely to initiate breastfeeding in comparison with their counterparts of normal weight. We did not find an independent effect of prepregnancy overweight/obesity on breastfeeding initiation among women with no medical problems. This group of women, however, had an 11% increased risk of stopping breastfeeding with each additional month of breastfeeding duration in comparison to those of normal weight. CONCLUSIONS: It is important to evaluate the health history and pregnancy complications among overweight/obese mothers in developing interventions for successful initiation and duration of breastfeeding.
