Independent association between uterine malformations and cervical insufficiency: a retrospective population-based cohort study

Objective

The purpose of our study was to explore maternal and fetal outcomes in the second and third trimester in women with uterine malformations.

Study design

This was a retrospective population-based cohort study including women with a diagnosis of uterine malformation arised from workup for infertility or recurrent pregnancy loss, was accidental during pregnancy, or was noticed at the time of cesarean delivery.

Results

A total of 280,721 pregnancies met the inclusion criteria and were divided into two study groups: (1) pregnancies in women with uterine malformations (n = 1099); and (2) controls (n = 279,662). The rate of women presenting uterine malformations was 0.39%. The prevalence of cervical os insufficiency was significantly higher in women with a uterine malformation than in the control group (3.6 vs. 0.4%, p < 0.001). A multivariate analysis, performed to evaluate risk factors for cervical insufficiency in women with uterine malformations. Mullerian anomalies (OR 6.19, 95% CI 4.41–8.70, p < 0.001), maternal age (OR 1.05, 95% CI 1.04–1.06, p < 0.001), recurrent abortions (OR 12.93, 95% CI 11.43–14.62, p < 0.001), and ethnicity (OR 2.86, 95% CI 2.454–3.34, p < 0.001) were found to be independently associated with the development of cervical insufficiency.

Conclusion

Uterine anomalies have a strong association with cervical insufficiency. Women with uterine anomalies have an increased risk to develop pregnancy complications that arise from a loss in cervical function during the midtrimester or early third trimester.

     

Anal incontinence after vaginal delivery: a five-year prospective cohort study

OBJECTIVE: The long-term prevalence of anal incontinence after vaginal delivery is unknown. The aim of the present study was to evaluate the prevalence of anal incontinence in primiparous women 5 years after their first delivery and to evaluate the influence of subsequent childbirth. METHODS: A total of 349 nulliparous women were prospectively followed up with questionnaires before pregnancy, at 5 and 9 months, and 5 years after delivery. A total of 242 women completed all questionnaires. Women with sphincter tear at their first delivery were compared with women without such injury. Risk factors for development of anal incontinence were also analyzed. RESULTS: Anal incontinence increased significantly during the study period. Among women with sphincter tears, 44% reported anal incontinence at 9 months and 53% at 5 years (P = .002). Twenty-five percent of women without a sphincter tear reported anal incontinence at 9 months and 32% had symptoms at 5 years (P < .001). Risk factors for anal incontinence at 5 years were age (odds ratio [OR] 1.1; 95% confidence interval [CI] 1.0-1.2), sphincter tear (OR 2.3; 95% CI 1.1-5.0), and subsequent childbirth (OR 2.4; 95% CI 1.1-5.6). As a predictor of anal incontinence at 5 years after the first delivery, anal incontinence at both 5 months (OR 3.8; 95% CI 2.0-7.3) and 9 months (OR 4.3; 95% CI 2.2-8.2) was identified. Among women with symptoms, the majority had infrequent incontinence to flatus, whereas fecal incontinence was rare. CONCLUSION: Anal incontinence among primiparous women increases over time and is affected by further childbirth. Anal incontinence at 9 months postpartum is an important predictor of persisting symptoms.     

Recurrence in a Schuchardt incision after Schauta–Amreich radical vaginal hysterectomy for cervical cancer

A Schuchardt incision is frequently performed to facilitate access to the parametrium during radical vaginal hysterectomy for cervical cancer. We report an adenocarcinoma recurrence in a Schuchardt incision 12 months after radical vaginal hysterectomy for FIGO stage IB1 cervical cancer. Histology of the primary tumor had shown a well-differentiated adenocarcinoma and poorly differentiated squamous cell carcinoma of the cervix 2.6 cm in maximum diameter. After further surgical therapy and adjuvant radiotherapy, the patient died of disease 51 months after the initial operation. Cervical cancers can implant and recur in perineal incisions. Thus, it appears prudent to avoid such incisions or, if they are made, to irrigate them copiously before closing them.     

Hysterectomy in obese women: a comparison of abdominal and vaginal routes

OBJECTIVE: To compare perioperative outcome measures of abdominal and vaginal hysterectomies in obese women. METHODS: We reviewed the charts of all obese women (body mass index more than 30 kg/m(2)) who underwent abdominal or vaginal hysterectomy for benign gynecologic conditions in our institution between 1997 and 2002. Laparoscopically assisted vaginal hysterectomies and hysterectomies with concomitant major pelvic or abdominal surgery were excluded. The rate of operative and postoperative complications, length of hospitalization, operative time, and perioperative change of hemoglobin concentration were analyzed for abdominal hysterectomy and vaginal hysterectomy. RESULTS: The study group consisted of 369 obese women, of whom 189 (51.2%) underwent abdominal, and 180 (48.8%), vaginal hysterectomy. Patient characteristics were statistically comparable between the groups except for uterine weight, which was higher in the abdominal group, and parity, which was greater for women who underwent vaginal hysterectomy (P <.05). After controlling for all the significantly different variables, vaginal hysterectomy resulted in lower incidence of postoperative fever (odds ratio [OR] 0.22, 95% confidence interval [CI] 0.12-0.39), ileus (OR 0.21, 95% CI 0.06-0.75), urinary tract infection (OR 0.21, 95% CI 0.06-0.75), shorter operative time (126.8 +/- 58.7 minutes compared with 109.7 +/- 68.5 minutes) and length of hospital stay (3.5 +/- 1.9 days compared with 1.9 +/- 1.1 days). Seven women (3.7%) who underwent abdominal hysterectomy developed wound infections during their hospital stay compared with none in the vaginal hysterectomy group. CONCLUSION: For obese women, vaginal hysterectomy is superior due to its lower incidence of postoperative fever, ileus, and urinary tract infection and shorter operative time and hospital stay. LEVEL OF EVIDENCE: II-2     

Anal incontinence after vaginal delivery: a prospective study in primiparous women

Objective To investigate the incidence and degree of anal incontinence after vaginal delivery among primiparous women and to define associated risk factors.
Design Prospective observational study.
Setting Karolinska Institutet, Danderyd Hospital, Sweden, a university hospital.
Participants Three hundred and forty-nine primiparous women.
Methods Questionnaires distributed within the first days after delivery and re-distributed five and nine months postpartum. Analysis of delivery records.
Results Eighty percent of the women answered all questionnaires. At five months postpartum, 2% of the women had symptoms of faecal incontinence and 25% had symptoms of involuntary flatus. At nine months postpartum, 1 % of the women had symptoms of faecal incontinence and 26% had symptoms of involuntary flatus. The majority of the women had infrequent symptoms and a decrease in severity was noted at nine months. Symptoms of incontinence were more common in women who sustained a sphincter tear at delivery. Risk factors for incontinence at five months included maternal age, duration of the second stage of labour, instrumental vaginal delivery, and clinically diagnosed sphincter tear at delivery. Development of incontinence at nine months was associated with maternal age and clinically diagnosed sphincter tear at delivery.
Conclusions The present study demonstrates that infrequent involuntary flatus is a common symptom after vaginal delivery in primiparous women. These symptoms of involuntary flatus frequently improved and only a few women suffered from frank faecal incontinence. Factors associated with an increased risk of anal incontinence and sphincter tears should be considered during delivery.

Tissue trauma after vaginal hysterectomy and colporrhaphy versus abdominal hysterectomy: a randomised controlled study

OBJECTIVE: As the magnitude of tissue trauma can be detected by measuring the blood levels of acute phase reactants, we aimed to evaluate tissue trauma markers after abdominal hysterectomy (AH) and vaginal hysterectomy (VH). We hypothesised that VH will be associated with a reduced increase in the level of acute phase reactants than AH. METHODS: Thirty women out of 92 patients scheduled for hysterectomies between June 2002 and June 2003 were randomised into two equal groups (n = 15) of VH and AH. Their levels of C-reactive protein (CRP), alpha1-antitrypsin (alpha1-AT) and myoglobin (M) were analysed preoperatively and on the second, fourth and sixth days. RESULTS: In both methods of hysterectomy, the operating time (85.3 +/- 6.57 min in the VH group vs 69 +/- 7.54 min in the AH group, P < 0.0001), and hospital stay duration (7.2 +/- 2.5 days in the AH group, 3.1 +/- 1.1 days in the VH group, P < 0.0001) were highly significantly different from each other. Demographic parameters and other parameters which may affect tissue trauma markers were not statistically significantly different in each group. Postoperative increases in all markers were markedly high and showed a high statistical difference in both groups (P < 0.05). The postoperative CRP and M values in both groups were significantly higher in the AH group on the second and fourth days and on the sixth day for M only, whereas alpha1-AT levels were only statistically different on the second day. The tissue trauma markers returned to normal levels on the sixth postoperative day for M, although there still was a statistically significant difference, but remained higher than normal for alpha1-AT and CRP. CONCLUSION: Whenever possible, VH should replace AH because this technique leads to a shorter hospital stay and less tissue trauma, enabling patients to return to their normal lives.     

Outcome after elective labor induction in nulliparous women: a matched cohort study

OBJECTIVE: To determine whether elective induction of labor in nulliparous women is associated with changes in fetomaternal outcome when compared with labor of spontaneous onset.Study Design: All 80 labor wards in Flanders (Northern Belgium) comprised a matched cohort study. From 1996 through 1997, 7683 women with elective induced labor and 7683 women with spontaneous labor were selected according to the following criteria: nulliparity, singleton pregnancy, cephalic presentation, gestational age at the time of delivery of 266 to 287 days, and birth weight between 3000 and 4000 g. Each woman with induced labor and the corresponding woman with spontaneous labor came from the same labor ward, and they had babies of the same sex. Both groups were compared with respect to the incidence of cesarean delivery or instrument delivery and the incidence of transfer to the neonatal ward. RESULTS: Cesarean delivery (9.9% vs 6.5%), instrumental delivery (31.6% vs 29.1%), epidural analgesia (80% vs 58%), and transfer of the baby to the neonatal ward (10.7% vs 9.4%) were significantly more common (P <.01) when labor was induced electively. The difference in cesarean delivery was due to significantly more first-stage dystocia in the induced group. The difference in neonatal admission could be attributed to a higher admission rate for maternal convenience when the women had a cesarean delivery. CONCLUSION: When compared with labor of spontaneous onset, elective labor induction in nulliparous women is associated with significantly more operative deliveries. Nulliparous women should be informed about this before they submit to elective induction.     

Thirty-day postoperative mortality after hysterectomy in women with liver cirrhosis: a Danish population-based cohort study

BACKGROUND: Women with liver cirrhosis have a higher incidence of hysterectomy than the general population, generally because of abnormal bleeding. They may also have an increased risk of postoperative mortality and morbidity. METHODS: In the nationwide Danish National Patients Register (NPR) we identified all women diagnosed with liver cirrhosis from 1977 to 1993. From this cohort we selected all women undergoing hysterectomy. A random sample of women without liver cirrhosis undergoing hysterectomy was selected as controls. Outcome was defined as mortality within the first 30 days after discharge. Logistic regression analysis was used to estimate the association between liver cirrhosis and 30-day postoperative mortality, adjusted for age, comorbidity, and type of admission. RESULTS: Out of 8539 women with liver cirrhosis 105 underwent hysterectomy. We found a 30-day postoperative mortality of 7.6% (95% confidence interval (CI) 2.5-12.7%) and 0.6% (95% CI 0.5-0.7%) in women with and without liver cirrhosis, respectively. The crude odds ratio was 14 (95% CI 6.5-29) and the adjusted odds ratio was 11 (95% CI 4.8-24) for 30-day postoperative mortality in women with liver cirrhosis compared with non-cirrhotic controls. CONCLUSION: Hysterectomy in women with liver cirrhosis is associated with an 11-fold increased risk of death within the first 30 days after discharge.     

First trimester vaginal bleeding and adverse pregnancy outcomes among Chinese women: from a large cohort study in China

Objectives: To examine the effect of first trimester vaginal bleeding on adverse pregnancy outcomes including preterm delivery, low birth weight and small for gestational age. Methods: This is a prospective population-based cohort study. A questionnaire survey was conducted on 4342 singleton pregnancies by trained doctors. Binary logistic regression was used to estimate risk ratios (RRs) and 95% con?dence intervals (95% CI). Results: Vaginal bleeding occurred among 1050 pregnant women, the incidence of vaginal bleeding was 24.2%, 37.4% of whom didn’t see a doctor, 62.6% of whom saw a doctor for vaginal bleeding. Binary logistic regression demonstrated that bleeding with seeing a doctor was significantly associated with preterm birth (RR 1.84, 95% CI 1.25–2.69) and bleeding without seeing a doctor was related to increased of low birth weight (RR 2.52, 95% CI 1.34–4.75) and was 1.97-fold increased of small for gestational age (RR 1.97, 95% CI 1.19–3.25). Conclusions: These results suggest that first trimester vaginal bleeding is an increased risk of low birth weight, preterm delivery and small for gestational age. Find ways to reduce the risk of vaginal bleeding and lower vaginal bleeding rate may be helpful to reduce the incidence of preterm birth, low birth weight and small for gestational age.     

Intrapartum pudendal nerve block analgesia and childbirth experience in primiparous women with vaginal birth: A cohort study

Background

A negative childbirth experience has short- and long-term consequences for both mother and child. This study aimed to investigate the association between intrapartum pudendal nerve block (PNB) analgesia and childbirth experience.

Methods

Primiparous women with a singleton cephalic vaginal live births at term at Oslo University Hospital from January 1, 2017, to June 1, 2019, were eligible for inclusion. The main outcome was total score on a childbirth experience questionnaire (range 1.0–4.0, higher score indicates better childbirth experience). An absolute risk difference of 0.10 was considered clinically relevant. Propensity score matching was used to adjust for differences in baseline characteristics between women with and without PNB. The analyses were stratified by spontaneous vs instrumental birth. Subanalyses of the questionnaire's domains (own capacity, professional support, perceived safety, and participation) were performed.

Results

Of 979 participating women, mean age was 32 years. Childbirth experience did not differ between women with and without PNB, either in spontaneous (absolute risk difference of the mean: −0.05, P value 0.36) or in instrumental birth (absolute risk difference of the mean: 0.03, P value 0.61). There were no statistically significant differences between PNB group scores for the separate domains.

Conclusions

Women's childbirth experiences did not differ between birthing people with or without PNB, either in spontaneous or in instrumental births. The clinical implications of our study should be interpreted in light of the pain-relieving effects of PNB.PNB should be provided on clinical indication, including for individuals with severe labor pain.     

Laparoscopic and abdominal sacral colpopexies: a comparative cohort study

OBJECTIVE: This study was undertaken to compare laparoscopic and open sacral colpopexies for efficacy and safety. STUDY DESIGN: Charts were reviewed for 56 patients who underwent laparoscopic sacral colpopexy and 61 patients who underwent open sacral colpopexy. Demographic and hospital data, complications, and follow-up visits were reviewed. RESULTS: Mean follow-up was 13.5 +/- 12.1 months and 15.7 +/- 18.1 months in the laparoscopic and open groups, respectively. Mean operating time was significantly greater in the laparoscopic versus open cohort, 269 +/- 65 minutes and 218 +/- 60 minutes, respectively (P < .0001). Estimated blood loss (172 +/- 166 mL vs 234 +/- 149 mL; P = .04) and hospital stay (1.8 +/- 1.0 days vs 4.0 +/- 1.8 days; P < .0001) were significantly less in the laparoscopic group than the open group. Complication and reoperation rates were similar. CONCLUSION: Laparoscopic and open sacral colpopexies have comparable clinical outcomes. Although laparoscopic sacral colpopexy requires longer operating time, hospital stay is significantly decreased.     

Cervical occlusion in women with cervical insufficiency: protocol for a randomised, controlled trial with cerclage, with and without cervical occlusion

OBJECTIVE: To evaluate the effect of double cerclage compared with a single cerclage. DESIGN: Randomised, controlled multicentre trial. SETTING: Ten different countries are participating with both secondary and tertiary centres. The countries participating are Denmark, Sweden, Germany, United Kingdom, Spain, South Africa, Australia and India. This gives both a broad spectrum of diversity global and local. We expect a total of 242 women enrolled per year. POPULATION: Prophylactic study: 1. History of cervical incompetence/insufficiency. (Delivery 15 to <36 weeks.) 2. Congenital short cervix (secondary to maternal administration of diethyl stilbestrol) or traumatic/surgical damage rendering the vaginal approach difficult (e.g. conisation). 3. Cervical suture applied in previous pregnancy, successful outcome. 4. Previous failed cerclage. Therapeutic study: 5. Secondary cerclage: Short cervix, without the membranes being exposed to the vagina. 6. Tertiary cerclage: Short cervix, membranes exposed to the vagina. Observational study: Eligible women who refuse to be randomised will participate in an observational study. 7. Repeat/requested cervical occlusion. METHODS: The women will be randomised between a single (vaginal or abdominal) and a double cerclage. The cervical cerclage (McDonald or Shirodkar) as well as the abdominal suture will be performed with the same material and technique normally used by the participating department. Those randomised to the double cerclage will have their external os closed with a continuous nylon 2-0/3-0 suture, in addition to the standard single cerclage. Local guidelines concerning antibiotics, Heparin, bed rest, tocolytics etc. are followed and recorded in the follow-up form. MAIN OUTCOME MEASURES: Primary endpoint is take home baby rate. The secondary endpoints are gestational age at delivery, incidence of preterm birth (<34+0 days) and number of days in neonatal unit.     

Laparoscopically assisted radical vaginal hysterectomy vs. radical abdominal hysterectomy for cervical cancer: a match controlled study

OBJECTIVES: The technical feasibility of laparoscopically assisted radical vaginal hysterectomy has been well described, but its advantages over the open technique remain largely unproven. We reviewed and compared our experiences with both approaches. METHODS: All patients undergoing laparoscopically assisted radical vaginal hysterectomy (LARVH) between 1996 and 2003 were identified and matched for age, FIGO stage, histological subtype and nodal metastases using a control group of women who underwent radical abdominal hysterectomy (RAH) during the same time period. RESULTS: Fifty-seven women were listed for LARVH, resulting in five conversions. Fifty cases were matched successfully using the criteria above. The majority of cases were FIGO stage 1B1. Statistically significant differences (P < 0.05) were present when the following were compared for LARVH vs. RAH: duration of surgery (median 180 vs. 120 min), blood loss (median 350 vs. 875 ml), hospital stay (median 5 days vs. 8 days) and duration of continuous bladder catheterisation (median 3 days vs. 7 days). There were no statistically significant differences with regard to nodal yield, completeness of surgical margins or perioperative complication rate. Four major complications (8%, three cystotomies and one enterotomy) occurred in the LARVH group and three in the RAH group (6%, one pulmonary embolism, one ureteric injury and one major haemorrhage). Three women in LARVH group had seen a specialist regarding postoperative bladder dysfunction, versus 12 in the RAH group (P = 0.04). No patients in the LARVH group reported constipation requiring regular laxatives, versus six in the RAH group (P = 0.03). Median follow-up was 52 months for LARVH and 49 months for RAH. There was no significant difference between recurrence rates or overall survival (94% for LARVH vs. 96% for RAH). CONCLUSIONS: Despite the inherent limitations of LARVH and its associated learning curve, the procedure conveys many advantages over the open technique in terms of blood loss, transfusion requirement and hospital stay. In addition, the incidence of postoperative bladder and bowel dysfunction appears low-suggesting improved quality of life-without compromising survival.     

Quantitative fetal fibronectin and cervical length in symptomatic women: results from a prospective blinded cohort study*

Objectives: Our objectives were to determine whether quantitative fetal fibronectin (fFN) and cervical length (CL) screening can be used alone or in combination as prognostic tests to identify symptomatic women at the highest or lowest risk for spontaneous preterm birth (sPTB).

Methods: A prospective, blinded cohort study of women presenting with a singleton gestation to our triage unit between 22-33w6d with preterm labor symptoms was performed. Women with ruptured membranes, moderate/severe bleeding, and dilation >2?cm were excluded. The primary outcome was sPTB <37 weeks. We evaluated test characteristics of quantitative fFN and CL assessment, both separately and in combination, considering traditionally reported cut-points (fFN ≥50 and CL <25), as well as cut-points above and below these measures. We found interactions between fFN >50 and CL <25 and sPTB by parity and obstetric history (p?Results: Five hundred eighty women were enrolled and 537 women were available for analysis. Overall sPTB rate was 11.1%. Among nulliparous women, increasing levels of fFN were associated with increasing risk of sPTB, with PPV going from 26.5% at ≥20?ng/mL to 44.4% at ≥200?ng/mL. A cut-point of 20?ng/mL had higher sensitivity (69.2%) and higher NPV (96.8%) and therefore identified a “low-risk” group. fFN was not informative for multiparous women regardless of prior obstetrical history or quantitative level chosen. For all women, a shorter CL was associated with an increased sPTB risk. Among nulliparas and multiparas without a prior sPTB, a CL <20?mm optimized test characteristics (PPV 25 and 20%, NPV 95.5, and 92.7%, respectively). For multiparas with a prior sPTB, CL <25?mm was more useful. Using fFN and CL in combination for nulliparas did not improve test characteristics over using the individual fFN (p?=?.74) and CL (p?=?.31) components separately.

Conclusions: This study identifies the importance of stratifying by parity and obstetrical history when using screening modalities for risk assessment in symptomatic women. For nulliparous women, either quantitative fFN or cervical length assessment can be utilized, depending on resources available, but a lower cut-point of 20?ng/mL should be used for quantitative fFN. For multiparous women, fFN is not useful and cervical length assessment should be the main screening tool utilized when there is clinical uncertainty. Regardless of parity, the PPV of fFN and CL is low and therefore the greatest clinical utility remains in its NPV.     

Diabetes Mellitus and lower genital tract tears after vaginal birth: A cohort study

IntroductionDiabetes Mellitus in pregnancy is increasing. No existing studies have examined Diabetes Mellitus as the primary exposure for lower genital tract tears after vaginal birth. The objective was to study the association between Diabetes Mellitus (all types combined), Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus and Gestational Diabetes Mellitus and lower genital tract tears after vaginal birth.Material and methodsA register-based cohort study of women with singleton pregnancy and without a previous cesarean section at near-term (≥ 35 + 0 weeks) and term (≥ 37 + 0 weeks) gestational age, n = 31,297 at Aarhus University Hospital, Denmark from 1 January 2004 to 31 December 2012. The associations between Diabetes Mellitus and lower genital tract tears were analysed using a fixed multiple logistic regression analyses.ResultsApproximately 32,000 women were eligible for the study; 796 women had diabetes (2.5%) and 1318 experienced anal sphincter injury (4.3%). The overall risk of lower genital tract tears was similar among women with a diagnosis of diabetes (Type1 Diabetes Mellitus, Type 2 Diabetes Mellitus, and Gestational Diabetes Mellitus) compared to women without diabetes, except for nulliparous women with Type1 Diabetes Mellitus who experienced a higher risk of episiotomies, crude and adjusted odds ratios (OR 2.13, 95% CI 1.14-3.97) and (OR 2.48, 95% CI 1.21-5.10), respectively.ConclusionsWomen with Diabetes Mellitus without a previous cesarean section who gave birth vaginally to a single child at term or near term did not experienced an increased risk of lower genital tract tears. However, nulliparous women with Type 1 Diabetes Mellitus experienced a higher risk of episiotomy. These results may be used to individualised counselling of women with Diabetes Mellitus regarding mode of birth and may reduce worries about genital tract tears in women with Diabetes Mellitus considering vaginal birth.     

Incidence, severity, and determinants of perineal pain after vaginal delivery: a prospective cohort study

OBJECTIVES: The purpose of this study was to determine the frequency of perineal pain in the 6 weeks after vaginal delivery and to assess the association between perineal trauma and perineal pain.Study design This was a prospective cohort study of parturients at 1 day, 7 days,' and 6 weeks' post partum in an academic tertiary obstetric unit in Toronto, Canada. Four hundred forty-four women were followed up, including women with an intact perineum (n=84), first-/second-degree tears (n=220), episiotomies (n=97), or third-/fourth-degree tears (n=46). Primary outcome was the incidence of perineal pain on day of interview; secondary outcomes were pain score measurements and interference with daily activities. RESULTS: Perineal trauma was more common among primiparous women, those with operative vaginal deliveries, and those with epidural analgesia during the second stage of labor. The incidence of perineal pain among the groups during the first week was intact perineum 75% (day 1) and 38% (day 7); first-/second-degree tears 95% and 60%; episiotomies 97% and 71%; and third-/fourth-degree tears 100% and 91%. By 6 weeks, the frequency of perineal pain was not statistically different between trauma groups. CONCLUSION: Acute postpartum perineal pain is common among all women. However, perineal pain was more frequent and severe for women with increased perineal trauma.
