Female and Male Fertility after Colectomy and Reconstructive Surgery in Inflammatory Bowel Diesase: A National Cohort Study from Sweden

BACKGROUND AND AIMS

Colectomy and reconstruction in patients with inflammatory bowel disease [IBD] may adversely affect fertility, but few population-based studies on this subject are available.

METHODS

Fertility was assessed in 2989 women and 3771 men with IBD and prior colectomy during 1964-2014, identified from the Swedish National Patient Register, and in 35 092 matched individuals.

RESULTS

Reconstruction with ileoanal pouch anastomosis [IPAA] was as common as ileorectal anastomosis [IRA] in ulcerative colitis [UC] and IBD-unclassified [IBD-U] but rare in Crohn's disease [CD]. Compared with the matched reference cohort, women with IBD had lower fertility overall after colectomy (hazard ratio [HR] 0.65, confidence interval [CI] 0.61-0.69), with least impact with leaving the rectum intact [HR 0.79, CI 0.70-0.90]. Compared with colectomy only, fertility in female patients remained unaffected after IRA [HR 0.86, CI 0.63-1.17 for UC, 0.86, CI 0.68-1.08 for IBD-U and 1.07, CI 0.70-1.63 for CD], but was impaired after IPAA, especially in UC [HR 0.67, CI 0.50-0.88], and after completion proctectomy [HR 0.65, CI 0.49-0.85 for UC, 0.68, CI 0.55-0.85 for IBD-U and 0.61, CI 0.38-0.96 for CD]. In men, fertility was marginally reduced following colectomy [HR 0.89, CI 0.85-0.94], regardless of reconstruction.

CONCLUSIONS

Fertility was reduced in women after colectomy for IBD. The least impact was seen when a deviated rectum was left intact. IRA was associated with no further reduction in fertility, whereas proctectomy and IPAA were associated with the strongest impairment. IRA therefore seems to be the preferred reconstruction to preserve fertility in selected female patients. Fertility in men was only moderately reduced after colectomy.

IBD and Motherhood: A Journey through Conception, Pregnancy and Beyond

Inflammatory Bowel Disease (IBD) presents distinct challenges during pregnancy due to its influence on maternal health and pregnancy outcomes. This literature review aims to dissect the existing scientific evidence on pregnancy in women with IBD and provide evidence-based recommendations for clinical management. A comprehensive search was conducted across scientific databases, selecting clinical studies, systematic reviews, and other pertinent resources. Numerous studies have underscored an increased risk of complications during pregnancy for women with IBD, including preterm birth, low birth weight, neonates small for gestational age, and congenital malformations. Nevertheless, it's evident that proactive disease management before and throughout pregnancy can mitigate these risks. Continuation of IBD treatment during pregnancy and breastfeeding is deemed safe with agents like thiopurines, anti-TNF, vedolizumab, or ustekinumab. However, there's a call for caution when combining treatments due to the heightened risk of severe infections in the first year of life. For small molecules, their use is advised against in both scenarios. Effective disease management, minimizing disease activity, and interdisciplinary care are pivotal in attending to women with IBD. The emphasis is placed on the continual assessment of maternal and infant outcomes and an expressed need for further research to enhance the understanding of the ties between IBD and adverse pregnancy outcomes.

Inflammatory bowel disease in pregnancy and breastfeeding

Inflammatory bowel disease (IBD) has a peak age of diagnosis before the age of 35 years. Concerns about infertility, adverse pregnancy outcomes, and heritability of IBD have influenced decision-making for patients of childbearing age and their care providers. The interplay between the complex physiology in pregnancy and IBD can affect placental development, microbiome composition and responses to therapy. Current evidence has shown that effective disease management, including pre-conception counselling, multidisciplinary care and therapeutic agents to minimize disease activity, can improve pregnancy outcomes. This Review outlines the management of IBD in pregnancy and the safety of IBD therapies, including novel agents, with regard to both maternal and fetal health. The vast majority of IBD therapies can be used with low risk during pregnancy and lactation without substantial effects on neonatal outcomes.

Australian inflammatory bowel disease consensus statements for preconception, pregnancy and breast feeding

OBJECTIVE

Because pregnancy outcomes tend to be worse in women with inflammatory bowel disease (IBD) than in those without, we aimed to update consensus statements that guide the clinical management of pregnancy in patients with IBD.

DESIGN

A multidisciplinary working group was established to formulate these consensus statements. A modified RAND/UCLA appropriateness method was used, consisting of a literature review, online voting, discussion meeting and a second round of voting. The overall agreement among the delegates and appropriateness of the statement are reported.

RESULTS

Agreement was reached for 38/39 statements which provide guidance on management of pregnancy in patients with IBD. Most medications can and should be continued throughout pregnancy, except for methotrexate, allopurinol and new small molecules, such as tofacitinib. Due to limited data, no conclusion was reached on the use of tioguanine during pregnancy. Achieving and maintaining IBD remission before conception and throughout pregnancy is crucial to optimise maternofetal outcomes. This requires a multidisciplinary approach to engage patients, allay anxieties and maximise adherence tomedication. Intestinal ultrasound can be used for disease monitoring during pregnancy, and flexible sigmoidoscopy or MRI where clinically necessary.

CONCLUSION

These consensus statements provide up-to-date, comprehensive recommendations for the management of pregnancy in patients with IBD. This will enable a high standard of care for patients with IBD across all clinical settings.

Impact of Female Gender in Inflammatory Bowel Diseases: A Narrative Review

Inflammatory bowel diseases show a gender bias, as reported for several other immune-mediated diseases. Female-specific differences influence disease presentation and activity, leading to a different progression between males and females. Women show a genetic predisposition to develop inflammatory bowel disease related to the X chromosome. Female hormone fluctuation influences gastrointestinal symptoms, pain perception, and the state of active disease at the time of conception could negatively affect the pregnancy. Women with inflammatory bowel disease report a worse quality of life, higher psychological distress, and reduced sexual activity than male patients. This narrative review aims to resume the current knowledge of female-related features in clinical manifestations, development, and therapy, as well as sexual and psychological implications related to inflammatory bowel disease. The final attempt is to provide gastroenterologists with a roadmap of female-specific differences, to improve patients' diagnosis, management, and treatment.

The Benefits and Drawbacks of Staging Pelvic Pouches

Since the mid-20th century, physicians have searched for way to improve the lives of patients with ulcerative colitis (UC). Early attempts of curative resection left the patients with a permanent stoma with only primitive stoma appliances available. Gradually, stoma care improved and operations were devised to give the patient bowel continuity without the need for a permanent ostomy. As these operations were evolving, benefits and drawbacks related to fertility, ease of small bowel reach to the pelvis, and postoperative pelvic sepsis were observed. In this article, we will elucidate the various ways pelvic pouches are used to treat UC and the rationale for the timing of surgery as well as the evolution of stoma care.

Elective and Emergent Surgery in the Ulcerative Colitis Patient

Ulcerative colitis (UC) requires surgical management in 20 to 30% of patients. Indications for surgery include medically refractory disease, dysplasia, cancer, and other complications of UC. Appropriate patient selection for timing and staging of surgery is paramount for optimal outcomes. Restorative proctocolectomy is the preferred standard of care and can afford many patients with excellent quality of life. There have been significant shifts in the treatment of UC-associated dysplasia, with less patients requiring surgery and more entering surveillance programs. There is ongoing controversy surrounding the management of UC-associated colorectal cancer and the techniques that should be used. This article reviews the most recent literature on the indications for elective and emergent surgical intervention for UC and the considerations behind the surgical options.

Ovarian reserve and IVF outcomes in patients with inflammatory bowel disease: A systematic review and meta-analysis

BACKGROUND

Inflammatory bowel disease (IBD) mainly affects people during reproductive age. However, it is unclear whether IBD might be associated with impaired ovarian reserve in female patients or with in vitro fertilization (IVF) outcomes.

METHODS

This systematic review and meta-analysis included articles from inception to May, 2022. Random-effect model was applied to calculate the standardized mean differences (SMDs) and odds ratios (ORs) and their 95% confidence intervals (95%CIs). Studies comparing the ovarian reserve or IVF outcomes of patients with IBD with the population were considered. To be included in this study, necessary measurements such as OR, relative risk (RR), SMD or hazard ratio (HR) or any necessary information to calculate them were provided in the articles. Letters, case reports, review articles including meta-analyses and expert opinions were excluded. For different articles studying the same population, the article with larger scale was selected.

FINDINGS

We included in our analysis 9 studies and data from 2386 IBD records and matched controls. Comparing with women without IBD, women with IBD had lower anti-mullerian hormone (AMH) levels (SMD = -0.38, 95%CI: -0.67, -0.09); (I² = 79.0%, p = 0.000). Patients with IBD of different ages showed distinct ovarian reserves, with patients below 30 years old not showing any decline in ovarian reserve compared to the control group (SMD = -0.56, 95%CI: -2.28, 1.16); (I² = 96.3%; p = 0.000), while patients with IBD over 30 years old (SMD = -0.75, 95%CI: -1.07, -0.43); (I² = 0.0%; p = 0.608) showed a decline compared to control group. Patients with IBD in remission stage had similar ovarian reserves to population (SMD = -0.10, 95%CI: -0.32, 0.12); (I² = 0.0%; p = 0.667), while patients in active stage showed an impaired ovarian reserve (SMD = -1.30, 95%CI: -1.64, -0.96); (I² = 0.0%; p = 0.318). Patients with IBD showed a pregnancy rate after receiving IVF treatment comparable to the control population (OR = 0.87, 95%CI: 0.55, 1.37); (I² = 70.1%, p = 0.035).

INTERPRETATION

The result of this study suggest that IBD may reduce reproductive age women's ovarian reserve and IVF treatment might help pregnancy outcomes in patients with impaired fertility. These results should be further validated in additional studies given the heterogeneity and quality of the studies included.

The impact of the ileoanal pouch on female fertility in ulcerative colitis: A systematic review and meta-analysis

AIM

Ileal pouch-anal anastomosis is a restorative option for patients with ulcerative colitis (UC) requiring surgery. The primary outcome of this study was the relative risk of infertility in women with UC undergoing restorative proctocolectomy (RPC) compared to the same patients before undergoing RPC. Infertility was defined as the inability to conceive after 1 year of regular sexual intercourse without contraception.

METHODS

A systematic review and meta-analysis were performed to include all relevant articles from 1946 from MEDLINE, Embase and Cochrane Central Register of Controlled Trials. Studies included reported on the fertility rate of a cohort with UC and also reported the rate after RPC in those within the cohort who underwent surgery. This study was registered on PROSPERO (CRD42021259745).

RESULTS

Thirteen studies met the inclusion criteria and accounted for 793 patients pre-pouch and 802 post-pouch. The mean and median age of the patients at analysis was 36.8 and 32.7 years respectively; and the median duration of follow-up following ileal pouch-anal anastomosis was 110.4 (68-139) months. Our results highlight that following RPC the relative risk of infertility is 4.17 (95% CI 1.99, 8.74) compared with patients before RPC who had UC.

CONCLUSIONS

The findings of this meta-analysis provide an update on a previous meta-analysis published over a decade ago and results remain congruent. This suggests that despite advancements in surgical techniques the risk to fertility remains similar to a decade ago. However, further high quality studies are needed to try and decipher independent risk factors associated with a decrease in infertility.

Post-Operative Functional Outcomes in Early Age Onset Rectal Cancer

Background

Impairment of bowel, urogenital and fertility-related function in patients treated for rectal cancer is common. While the rate of rectal cancer in the young (<50 years) is rising, there is little data on functional outcomes in this group.

Methods

The REACCT international collaborative database was reviewed and data on eligible patients analysed. Inclusion criteria comprised patients with a histologically confirmed rectal cancer, <50 years of age at time of diagnosis and with documented follow-up including functional outcomes.

Results

A total of 1428 (n=1428) patients met the eligibility criteria and were included in the final analysis. Metastatic disease was present at diagnosis in 13%. Of these, 40% received neoadjuvant therapy and 50% adjuvant chemotherapy. The incidence of post-operative major morbidity was 10%. A defunctioning stoma was placed for 621 patients (43%); 534 of these proceeded to elective restoration of bowel continuity. The median follow-up time was 42 months. Of this cohort, a total of 415 (29%) reported persistent impairment of functional outcomes, the most frequent of which was bowel dysfunction (16%), followed by bladder dysfunction (7%), sexual dysfunction (4.5%) and infertility (1%).

Conclusion

A substantial proportion of patients with early-onset rectal cancer who undergo surgery report persistent impairment of functional status. Patients should be involved in the discussion regarding their treatment options and potential impact on quality of life. Functional outcomes should be routinely recorded as part of follow up alongside oncological parameters.

Gastroenterology team members' knowledge and practices with fertility therapy for women with inflammatory bowel disease

INTRODUCTION

Fecundity may be reduced in women with active inflammatory bowel disease (IBD) or prior IBD-related surgery, and these women may require assisted reproductive technology (ART). There are no guidelines for women with IBD to outline referral criteria for ART.

METHODS

We performed a prospective, multicentre, international questionnaire of gastroenterologists, gastroenterology trainees, and IBD nurses. The primary outcome was to establish clinical practices and fertility therapy referral patterns among gastroenterology team members. We hypothesised that the lack of knowledge and awareness may delay or prevent initiation of fertility consultation referrals.

DISCUSSION

Of 182 participants, most had never initiated a referral for fertility therapy (69.8%), and of respondents who do initiate referrals, 50% wait until the patient has been unsuccessfully attempting conception for 12 months. Participants were significantly more likely to initiate a fertility therapy referral if they believed ART was effective (p = 0.038), not impeded by IBD-related surgery (p = 0.053), and if they had access to a dedicated IBD-pregnancy clinic (p = 0.027). Superior pregnancy knowledge was predictive of a greater likelihood of fertility therapy referrals (p = 0.037). All participants thought they had inadequate knowledge about ART in IBD, and 96.2% expressed desire to improve their knowledge.

CONCLUSION

Gastroenterology team members infrequently initiate referrals for fertility therapy consultation in women with IBD, increasing their risk of remaining childless. Implementation of dedicated IBD pregnancy clinics and targeted education programmes to increase awareness of ART in women with IBD might increase referral rates and reduce infertility.

OUP accepted manuscript

Background

Inflammatory bowel disease (IBD) negatively affects fertility and fecundity. We aimed to determine longitudinal trends in and factors that affect pregnancy rates in women with ulcerative colitis (UC) and Crohn’s disease (CD).

Methods

Women in the University of Manitoba IBD Epidemiology Database aged 15 to 45 were identified between 1992 and 2018 and matched up to 10 non-IBD controls. Pregnancy and live birth rates were compared between women with and without UC or CD stratified by time-period, disease duration and maternal age at conception. Incidence rate ratios (IRR) with 95% confidence intervals (CI) were calculated. Poisson regression was used to adjust these rates for year of pregnancy, disease duration, maternal age, severity of IBD, and prior IBD-related surgery.

Results

Compared to controls, women with UC had lower rates of pregnancies (IRR 0.91, 95% CI: 0.82–0.99) and women with CD had lower rates of pregnancies (IRR 0.85, 95% CI: 0.79–0.93) and live births (IRR 0.83, 95% CI: 0.75–0.92). Although rates of pregnancies and live births were significantly lower in women with UC and CD compared to controls prior to 2010, there appeared to be no differences between the two groups after 2010. Prior intestinal surgery and active disease at conception appeared to lower pregnancy rates in women with UC and CD, respectively.

Conclusion

This study demonstrates that women with IBD have lower pregnancy rates compared to those without IBD, though these differences are no longer evident after 2010. Factors that continue to reduce these rates include prior colectomy and underlying disease activity.

Female reproductive health and inflammatory bowel disease: A practice-based review

Inflammatory bowel diseases, namely ulcerative colitis and Crohn's disease, occur worldwide and affect people of all ages, with a high impact on their quality of life. Sex differences in incidence and prevalence have been reported, and there are also gender-specific issues that physicians should recognize. For women, there are multiple, important concerns regarding issues of body image and sexuality, menstruation, contraception, fertility, pregnancy, breastfeeding and menopause. This practice-based review focuses on the main themes that run through the life of women with inflammatory bowel diseases from puberty to menopause. Gastroenterologists who specialize in inflammatory bowel diseases and other physicians who see female patients with inflammatory bowel diseases should provide support for these problems and offer adequate therapy to ensure that their patients achieve the same overall well-being and health as do women without inflammatory bowel diseases.

Prevalence and risk factors of sexual dysfunction in patients with inflammatory bowel disease: systematic review and meta-analysis

PURPOSE

Sexual dysfunction (SD) is increasingly identified in patients with inflammatory bowel disease (IBD), but there are few systematic reviews and meta-analyses of the studies of SD in IBD patients. The purpose of the study is to further quantify the association between IBD and SD.

METHODS

MEDLINE (OVID), EMBASE (OVID), and the Cochrane Library (OVID) were searched (until August 2020) to identify observational studies that reported the prevalence and risk factors of SD in IBD patients. Pooled prevalence, odds ratios (ORs), and 95% confidence intervals (95% CIs) were calculated.

RESULTS

Of the 945 citations evaluated, 18 studies (including 36,676 subjects) reporting the prevalence of SD in the IBD population were included for analysis. The overall pooled prevalence was 39% (95% CI 37-40%, P < 0.001). The prevalence of SD in women was 53% (95% CI 50-55%, P < 0.001), and it was 27% (95% CI 25-29%, P < 0.001) in men. The prevalence was higher in conjunction with operation (OR, 1.33, 95% CI 1.22-1.45, P < 0.001), depression (OR 6.14, 95% CI 3.51-10.76, P < 0.001), disease activity (OR 2.73, 95% CI 1.32-5.64, P = 0.007), comorbidities (OR 3.21, 95% CI 2.06-5.00, P < 0.001), age < 50 years (OR 3.85, 95% CI 2.41-6.14, P < 0.001), and the need for corticosteroids (OR 2.62, 95% CI 1.48-4.66, P = 0.001).

CONCLUSION

SD occurred frequently in the IBD population. Operation, depression, disease activity, comorbidities, age < 50 years, and the need for corticosteroids were risk factors for SD in IBD patients. SD screening might be recommended in IBD patients with the aforementioned factors.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines 2020 for the Clinical Practice of Hereditary Colorectal Cancer

Hereditary colorectal cancer (HCRC) accounts for < 5% of all colorectal cancer cases. Some of the unique characteristics commonly encountered in HCRC cases include early age of onset, synchronous/metachronous cancer occurrence, and multiple cancers in other organs. These characteristics necessitate different management approaches, including diagnosis, treatment or surveillance, from sporadic colorectal cancer management. There are two representative HCRC, named familial adenomatous polyposis and Lynch syndrome. Other than these two HCRC syndromes, related disorders have also been reported. Several guidelines for hereditary disorders have already been published worldwide. In Japan, the first guideline for HCRC was prepared by the Japanese Society for Cancer of the Colon and Rectum (JSCCR), published in 2012 and revised in 2016. This revised version of the guideline was immediately translated into English and published in 2017. Since then, several new findings and novel disease concepts related to HCRC have been discovered. The currently diagnosed HCRC rate in daily clinical practice is relatively low; however, this is predicted to increase in the era of cancer genomic medicine, with the advancement of cancer multi-gene panel testing or whole genome testing, among others. Under these circumstances, the JSCCR guidelines 2020 for HCRC were prepared by consensus among members of the JSCCR HCRC Guideline Committee, based on a careful review of the evidence retrieved from literature searches, and considering the medical health insurance system and actual clinical practice settings in Japan. Herein, we present the English version of the JSCCR guidelines 2020 for HCRC.

Review of pregnancy in Crohn's disease and ulcerative colitis

Inflammatory bowel disease (IBD) frequently affects women of childbearing age and can have implications in pregnancy. Most women with IBD have comparable fertility with women in the general population. Fertility is reduced in women with active disease or previous ileal-pouch-anal anastomosis (IPAA) surgery and is temporarily reduced in men taking sulfasalazine. Women with IBD have an increased risk of preterm delivery, low birth weight, small-for-gestational-age infants and Cesarean section (CS) delivery, however, no increased risk of congenital abnormalities. These adverse outcomes are particularly prevalent for women with active IBD compared with those with quiescent disease. Conception should occur during disease remission to optimize maternal and fetal outcomes and reduce the risk of disease exacerbations during pregnancy. Pre-conception counseling is therefore pertinent to provide patient education, medication review for risk of teratogenicity and objective disease assessment. Most medications are safe during pregnancy and breastfeeding, with the exception of methotrexate, ciclosporin, allopurinol and tofacitinib. Delivery modality should be guided by obstetric factors in most cases; however, CS is recommended for women with active perianal disease and can be considered for women with inactive perianal disease or IPAA. In conclusion, most women with IBD have uncomplicated pregnancies. Active IBD is the predominant predictor of poor outcomes and disease exacerbations; therefore, maintenance of disease remission during and before pregnancy is crucial.

Pregnancy and medications in inflammatory bowel disease

Inflammatory bowel disease (IBD) affects patients at a significant time in their lives, often coinciding with family planning or pregnancy. While advances in IBD therapies have afforded women greater opportunities for successful conception and pregnancy outcomes, there still remains considerable maternal fear surrounding continuation of treatment in pregnancy. With the exception of methotrexate, most IBD drugs are safe and well tolerated during pregnancy and are not associated with significant risk of adverse fetal or pregnancy outcomes. Furthermore, the current evidence overwhelmingly suggests that good control of disease activity and clinical remission at time of conception are the greatest prognostic factors for an uncomplicated pregnancy and maintenance of quiescent disease. Management of pregnant women with IBD should involve discussions with the mother and family about fears or concerns surrounding the impact of IBD on pregnancy. Mothers should be supported and counselled carefully on the safety and importance of adherence to therapy in maintaining remission. Optimal management of these women requires an inter-disciplinary team effort, involving the general practitioner, in close consultation with both gastroenterologists and obstetricians.

Fertility Impact of Initial Operation Type for Female Ulcerative Colitis Patients

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) is the mainstay of surgical treatment for patients with ulcerative colitis (UC) but is associated with an increased risk of infertility. We developed a simulation model examining the impact of initial surgical procedure on quality-adjusted life-years (QALYs) and fertility end points.

METHODS

A patient-level state transition model was used to analyze outcomes by surgical approach strategy for females of childbearing age. Initial surgical options included IPAA, rectal-sparing colectomy with end ileostomy (RCEI), and ileorectal anastomosis (IRA). The primary outcome examined was QALYs, whereas secondary outcomes included UC and fertility-associated end points.

RESULTS

IPAA resulted in higher QALYs for patients aged 20-30 years, as compared with RCEI. For patients aged 35 years, RCEI resulted in higher QALYs (7.54 RCEI vs 7.53 IPAA) and was associated with a 28% higher rate of childbirth, a 14-month decrease in time to childbirth, and a 77% reduction in in vitro fertilization utilization. When accounting for the decreased infertility risk associated with laparoscopic IPAA, IPAA resulted in higher QALYs (7.57) even for patients aged 35 years.

CONCLUSIONS

Despite an increased risk of infertility, our model results suggest that IPAA may be the optimal surgical strategy for female UC patients aged 20-30 years who desire children. For patients aged 35 years, RCEI should additionally be considered, as QALYs for RCEI and IPAA were similar. These quantitative data can be used by patients and providers to help develop an individualized approach to surgical management choice.

Impact on Fertility After Failure of Restorative Proctocolectomy in Men and Women With Ulcerative Colitis: A 17-Year Cohort Study

BACKGROUND

Impact of restorative proctocolectomy failure on fertility has not been studied and is greatly relevant.

OBJECTIVE

The purpose of this study was to evaluate the impact of restorative proctocolectomy failure on birth rate in women and men, along with in vitro fertilization incidence and success.

DESIGN

This was a retrospective registry-based cohort study over 17 years.

SETTINGS

Records for parenting a child were cross-linked with patient records. In women, in vitro fertilization records were cross-linked. All data were prospectively registered.

PATIENTS

Patients of fertile age with ulcerative colitis between 1994 and 2010 were identified in Danish national databases. Patients with restorative proctocolectomy and restorative proctocolectomy failure were identified as subgroups.

MAIN OUTCOME MEASURES

Birth rate ratios and in vitro fertilization incidence and success were measured.

RESULTS

We included 11,939 women and 13,569 men with ulcerative colitis. A total of 711 women and 730 men had restorative proctocolectomy; 114 women and 90 men had failure. Birth rate in women with failure was significantly reduced compared with women without (birth rate ratio = 0.50 (95% CI, 0.29-0.82)). In men with failure, birth rate tended to be lower compared with men without (birth rate ratio = 0.74 (95% CI, 0.51-1.05)). In vitro fertilization incidence was similar with and without failure (HRs adjusted for age at start of follow-up = 0.98 (95% CI, 0.58-1.67]). In vitro fertilization success was significantly lower with failure compared with ulcerative colitis (OR adjusted for age at start of follow-up = 0.36 (95% CI, 0.4-0.92)).

LIMITATIONS

Information on patients leading up to restorative proctocolectomy failure is lacking. Failure patients may have had children during a period with pouch function. Therefore, the impact of failure may be underestimated.

CONCLUSIONS

Restorative proctocolectomy failure impairs birth rate, primarily in women. Although in vitro fertilization incidence is similar in women with and without failure, the likelihood of giving birth after in vitro fertilization is reduced.

Risk Factors Associated with Impaired Ovarian Reserve in Young Women of Reproductive Age with Crohn's Disease

BACKGROUND/AIMS

Crohn's disease (CD) primarily affects young female adults of reproductive age. Few studies have been conducted on this population's ovarian reserve status. The aim of study was to investigate potential risk factors associated with low ovarian reserve, as reflected by serum anti-Müllerian hormone (AMH) in women of reproductive age with CD.

METHODS

This was a case-control study. Cases included 87 patients with established CD, and healthy controls were matched by age, height and weight in a 1:1 ratio. Serum AMH levels were measured by enzyme-linked immunosorbent assay.

RESULTS

The average serum AMH level was significantly lower in CD patients than in control group (2.47±2.08 ng/mL vs. 3.87±1.96 ng/mL, respectively, P<0.001). Serum AMH levels were comparable between CD patients and control group under 25 years of age (4.41±1.52 ng/mL vs. 3.49±2.10 ng/mL, P=0.06), however, serum AMH levels were significantly lower in CD patients over 25 years of age compared to control group (P<0.05). Multivariable analysis showed that an age greater than 25 (odds ratio [OR], 10.03; 95% confidence interval [CI], 1.90-52.93, P=0.007), active disease state (OR, 27.99; 95% CI, 6.13-127.95, P<0.001) and thalidomide use (OR, 15.66; 95% CI, 2.22-110.65, P=0.006) were independent risk factors associated with low ovarian reserve (serum AMH levels <2 ng/mL) in CD patients.

CONCLUSIONS

Ovarian reserve is impaired in young women of reproductive age with CD. Age over 25 and an active disease state were both independently associated with low ovarian reserve. Thalidomide use could result in impaired ovarian reserve.

Surgery for Inflammatory Bowel Disease Has Unclear Impact on Female Fertility: A Cochrane Collaboration Systematic Review

Background and Aims

Surgical treatment of inflammatory bowel disease (IBD) may impair female fertility. We conducted a systematic review to determine the risk of infertility and pregnancy outcomes in women with IBD who underwent surgery.

Methods

We identified studies evaluating the impact of IBD surgery on infertility and pregnancy outcomes. Risk ratios (RR) and 95% confidence intervals (CIs) were pooled when data were presented using contingency tables. Odds ratios (OR) were pooled when raw numbers were not provided. GRADE was used to evaluate the certainty of evidence.

Results

Sixteen observational studies were included, comparing women with and without surgery, open and laparoscopic surgery and before and after surgery. All studies were of low quality. The effect of surgery on infertility at 12 months (RR 5.45, 95% CI 0.41 to 72.57) was uncertain. Similarly, the fertility effects of laparoscopic versus open surgery method were unclear (RR 0.70, 95% CI 0.38 to 1.27). The impact of IBD surgery on pregnancy outcomes should be interpreted with caution. Surgery was associated with miscarriage (OR 2.03, 95% CI 1.14 to 3.60), use of assisted reproductive technologies (RR 25.09, 95% CI 1.56 to 403.76) and caesarean section (RR 2.23, 95% CI 1.00 to 4.95), but not with stillbirth (RR 1.96, 95% CI 0.42 to 9.18), preterm birth (RR 1.91, 95% CI 0.67 to 5.48), low birth weight (RR 0.61, 95% CI 0.08 to 4.83) or small for gestational age (RR 2.54, 95% CI 0.80 to 8.01).

Conclusion

The effect of surgical therapy for IBD on rates of female infertility and pregnancy-related outcomes was uncertain due to poor quality of existing literature.

Inflammatory bowel disease position statement of the Italian Society of Colorectal Surgery (SICCR): ulcerative colitis

The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a Position Statement of Italian colorectal surgeons to address the surgical aspects of ulcerative colitis management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the surgical treatment of ulcerative colitis. The committee was able to identify some points of major disagreement and suggested strategies to improve the quality of available data and acceptance of guidelines.

Surgery and paediatric inflammatory bowel disease

The incidence of paediatric Crohn's disease (CD) and ulcerative colitis (UC) is increasing. Surgical intervention is required during childhood in approximately 25% of children diagnosed with CD, and for 10% of those diagnosed with UC. Although there is evidence that the rate of surgical intervention undertaken in children is decreasing since the introduction of biologic therapy, this may only represent a delay rather than true reversal of the risk of surgery. Surgery for CD is not curative and limited resection is the key principle thus preserving bowel length. For UC, subtotal colectomy is relatively curative; ileo-anal pouch anastomosis can be performed to restore bowel continuity.

Use and Success of In Vitro Fertilisation Following Restorative Proctocolectomy and Ileal Pouch-anal Anastomosis. A Nationwide 17-year Cohort Study

BACKGROUND AND AIMS

Fertility decreases in women following restorative proctocolectomy for ulcerative colitis. The use and success of in vitro fertilisation [IVF] after restorative proctocolectomy for ulcerative colitis is not systematically studied. We aimed to estimate the use and success of in vitro fertilisation treatment in female ulcerative colitis patients, with and without restorative proctocolectomy.

METHODS

Women of fertile age [15-49 years] with restorative proctocolectomy for ulcerative colitis were compared with females with ulcerative colitis without restorative proctocolectomy. Data from the IVF registry from 1994-2010 were cross-linked with data from the National Danish Patient Registry and the Medical Birth Registry.

RESULTS

In vitro fertilisation is significantly more frequent in females with restorative proctocolectomy compared with females without restorative proctocolectomy, adjusted hazard ratio 3.2, 95% confidence interval [CI] [2.5;4.0]. The odds for having a live birth after in vitro fertilisation are no different in females with restorative proctocolectomy compared with females without restorative proctocolectomy, adjusted odds ratio 0.8, 95% CI [0.6;1.1]. The percentage of children born as a result of in vitro fertilisation is significantly higher in females with restorative proctocolectomy compared with females without restorative proctocolectomy (31.0%, 95% CI [24.1; 37.7] vs 5.0%, 95% CI [4.4; 5.6]).

CONCLUSIONS

Females with restorative proctocolectomy for ulcerative colitis have increased incidence of in vitro fertilisation by more than a factor three, the odds that a treatment results in a live birth are similar and six times more children are born as a result of in vitro fertilisation compared with females without restorative proctocolectomy.

The impact of surgical therapies for inflammatory bowel disease on female fertility

BACKGROUND

Women with inflammatory bowel disease (IBD) may require surgery, which may result in higher risk of infertility. Restorative proctocolectomy with ileal anal pouch anastomosis (IPAA) may increase infertility, but the degree to which IPAA affects infertility remains unclear, and the impact of other surgical interventions on infertility is unknown.

OBJECTIVES

Primary objective• To determine the effects of surgical interventions for IBD on female infertility.Secondary objectives• To evaluate the impact of surgical interventions on the need for assisted reproductive technology (ART), time to pregnancy, miscarriage, stillbirth, prematurity, mode of delivery (spontaneous vaginal, instrumental vaginal, or Caesarean section), infant requirement for resuscitation and neonatal intensive care, low and very low birth weight, small for gestational age, antenatal and postpartum hemorrhage, retained placenta, postpartum depression, gestational diabetes, and gestational hypertension/preeclampsia.

SEARCH METHODS

We searched MEDLINE, Embase, CENTRAL, and the Cochrane IBD Group Specialized Register from inception to September 27, 2018, to identify relevant studies. We also searched references of relevant articles, conference abstracts, grey literature, and trials registers.

SELECTION CRITERIA

We included observational studies that compared women of reproductive age (≥ 12 years of age) who underwent surgery to women with IBD who had a different type of surgery or no surgery (i.e. treated medically). We also included studies comparing women before and after surgery. Any type of IBD-related surgery was permitted. Infertility was defined as an inability to become pregnant following 12 months of unprotected intercourse. Infertility at 6, 18, and 24 months was included as a secondary outcome. We excluded studies that included women without IBD and those comparing women with IBD to women without IBD..

DATA COLLECTION AND ANALYSIS

Two review authors independently screened studies and extracted data. We used the Newcastle-Ottawa Scale to assess bias and GRADE to assess the overall certainty of evidence. We calculated the pooled risk ratio (RR) and 95% confidence interval (CI) using random-effects models. When individual studies reported odds ratios (ORs) and did not provide raw numbers, we pooled ORs instead.

MAIN RESULTS

We identified 16 observational studies for inclusion. Ten studies were included in meta-analyses, of which nine compared women with and without a previous IBD-related surgery and the other compared women with open and laparoscopic IPAA. Of the ten studies included in meta-analyses, four evaluated infertility, one evaluated ART, and seven reported on pregnancy-related outcomes. Seven studies in which women were compared before and after colectomy and/or IPAA were summarized qualitatively, of which five included a comparison of infertility, three included the use of ART, and three included other pregnancy-related outcomes. One study included a comparison of women with and without IPAA, as well as before and after IPAA, and was therefore included in both the meta-analysis and the qualitative summary. All studies were at high risk of bias for at least two domains.We are very uncertain of the effect of IBD surgery on infertility at 12 months (RR 5.45, 95% CI 0.41 to 72.57; 114 participants; 2 studies) and at 24 months (RR 3.59, 95% CI 1.32 to 9.73; 190 participants; 1 study). Infertility was lower in women who received laparoscopic surgery compared to open restorative proctocolectomy at 12 months (RR 0.70, 95% CI 0.38 to 1.27; 37 participants; 1 study).We are very uncertain of the effect of IBD surgery on pregnancy-related outcomes, including miscarriage (OR 2.03, 95% CI 1.14 to 3.60; 776 pregnancies; 5 studies), use of ART (RR 25.09, 95% CI 1.56 to 403.76; 106 participants; 1 study), delivery via Caesarean section (RR 2.23, 95% CI 1.00 to 4.95; 20 pregnancies; 1 study), stillbirth (RR 1.96, 95% CI 0.42 to 9.18; 246 pregnancies; 3 studies), preterm birth (RR 1.91, 95% CI 0.67 to 5.48; 194 pregnancies; 3 studies), low birth weight (RR 0.61, 95% CI 0.08 to 4.83), and small for gestational age (RR 2.54, 95% CI 0.80 to 8.01; 65 pregnancies; 1 study).Studies comparing infertility before and after IBD-related surgery reported numerically higher rates of infertility at six months (before: 1/5, 20.0%; after: 9/15, 60.0%; 1 study), at 12 months (before: 68/327, 20.8%; after: 239/377, 63.4%; 5 studies), and at 24 months (before: 14/89, 15.7%; after: 115/164, 70.1%; 2 studies); use of ART (before: 5.3% to 42.2%; after: 30.3% to 34.3%; proportions varied across studies due to differences in which women were identified as at risk of using ART); and delivery via Caesarean section (before: 8/73, 11.0%; after: 36/75, 48.0%; 2 studies). In addition, women had a longer time to conception after surgery (two to five months; 2 studies) than before surgery (5 to 16 months; 2 studies). The proportions of women experiencing miscarriage (before: 19/123, 15.4%; after: 21/134, 15.7%; 3 studies) and stillbirth (before: 2/38, 5.3%; after: 3/80: 3.8%; 2 studies) were similar before and after surgery. Fewer women experienced gestational diabetes after surgery (before: 3/37, 8.1%; after: 0/37; 1 study), and the risk of preeclampsia was similar before and after surgery (before: 2/37, 5.4%; after: 0/37; 1 study). We are very uncertain of the effects of IBD-related surgery on these outcomes due to poor quality evidence, including confounding bias due to increased age of women after surgery.We rated evidence for all outcomes and comparisons as very low quality due to the observational nature of the data, inclusion of small studies with imprecise estimates, and high risk of bias among included studies.

AUTHORS' CONCLUSIONS

The effect of surgical therapy for IBD on female infertility is uncertain. It is also uncertain if there are any differences in infertility among those undergoing open versus laparoscopic procedures. Previous surgery was associated with higher risk of miscarriage, use of ART, Caesarean section delivery, and giving birth to a low birth weight infant, but was not associated with risk of stillbirth, preterm delivery, or delivery of a small for gestational age infant. These findings are based on very low-quality evidence. As a result, definitive conclusions cannot be made, and future well-designed studies are needed to fully understand the impact of surgery on infertility and pregnancy outcomes.

The Association of Coloproctology of Great Britain and Ireland consensus guidelines in surgery for inflammatory bowel disease

AIM

There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology.

METHODS

Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines.

RESULTS

All aspects of surgical care for IBD have been included along with 157 recommendations for management.

CONCLUSION

These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

Surgery in ulcerative colitis: When? How?

Ulcerative Colitis (UC) is an idiopathic chronically-remitting inflammatory bowel disorder characterized by a contiguous inflammation of the colonic mucosa affecting the rectum that generally extends proximally in a continuous manner through the entire colon. Patients typically experience intermittent exacerbations, with symptoms characterized by bloody diarrhea associated with urgency and tenesmus. The anatomical extent of mucosal involvement is the most important factor determining disease course and is an important predictor of colectomy. The precise etiology of UC is unknown. However, a combination of genetic predisposition and environmental factors seems to have a key role in the development of the disease. UC usually is mildly active but it can be a life-threatening condition because of colonic and systemic complications, and later in the disease course due to the development of colorectal cancer. Interestingly, even if pathogenetic features detected in patients with sporadic CRC can be also found in UC-related colorectal cancer (UC-CRC), this latter is, usually, driven by an inflammation-driven pathway rising from a non-neoplastic inflammatory epithelium to dysplasia to cancer. Thus, a long-term follow-up with colonoscopy surveillance has been recommended. Approximately 15% of UC patients develop an acute attack of severe colitis, and 30% of these patients require colectomy. The initial treatment strategy in UC typically follows the traditional step-up approach. One third of the patients will not respond to steroid therapy and cyclosporine and infliximab are the most common salvage agents employed in these cases in order to avoid emergent surgery. Unfortunately, although a significant short-term benefit have been observed after infliximab treatment, the colectomy rate have remained stable. Surgery in UC depends on the stage of the disease as well as patient's status and is divided into the following settings: urgent, emergent and elective. Despite many efforts the surgical management of UC remains a significant challenge. A multidisciplinary management of UC is key in order to define the best timing and the best procedure for each patient in an individualized basis.

Gastro-intestinal surgery and fertility

In France, 10 to 15% of couples in the overall population have a fertility problem. Preservation of sexual and reproductive function should be a major concern for all patients capable of procreation who undergo treatment for gastro-intestinal disease. The gastro-intestinal diseases most often responsible for fertility disorders include chronic inflammatory diseases, intestinal cancer and hereditary diseases, such as the Lynch syndrome and familial adenomatous polyposis. Obesity is responsible for a 20% loss of fertility but the effects of bariatric surgery on fertility are controversial. Nonetheless, in the light of progress in surgical techniques and better knowledge of gastro-intestinal disease the negative impact of surgery on fertility warrants attention. Effectively, fertility can be preserved after certain major gastro-intestinal operations such as cytoreductive surgery with intraperitoneal chemotherapy, total coloprotectomy with ileo-anal anastomosis and rectosigmoid resection, as long as the patient's age permits and resection of the reproductive organs is not necessary.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) Guidelines 2016 for the Clinical Practice of Hereditary Colorectal Cancer (Translated Version)

Hereditary colorectal cancer accounts for less than 5% of all colorectal cancer cases. Some of the unique characteristics that are commonly encountered in cases of hereditary colorectal cancer include early age at onset, synchronous/metachronous occurrence of the cancer, and association with multiple cancers in other organs, necessitating different management from sporadic colorectal cancer. While the diagnosis of familial adenomatous polyposis might be easy because usually 100 or more adenomas that develop in the colonic mucosa are in this condition, Lynch syndrome, which is the most commonly associated disease with hereditary colorectal cancer, is often missed in daily medical practice because of its relatively poorly defined clinical characteristics. In addition, the disease concept and diagnostic criteria for Lynch syndrome, which was once called hereditary non-polyposis colorectal cancer, have changed over time with continual research, thereby possibly creating confusion in clinical practice. Under these circumstances, the JSCCR Guideline Committee has developed the "JSCCR Guidelines 2016 for the Clinical Practice of Hereditary Colorectal Cancer (HCRC)," to allow delivery of appropriate medical care in daily practice to patients with familial adenomatous polyposis, Lynch syndrome, or other related diseases. The JSCCR Guidelines 2016 for HCRC were prepared by consensus reached among members of the JSCCR Guideline Committee, based on a careful review of the evidence retrieved from literature searches, and considering the medical health insurance system and actual clinical practice settings in Japan. Herein, we present the English version of the JSCCR Guidelines 2016 for HCRC.

Current Approaches to Pediatric Polyposis Syndromes

Colorectal adenomatous polyposis syndromes encompass a diverse group of disorders with varying modes of inheritance and penetrance. Children may present with overt disease or within screening programs for families at high risk. We provide an overview of the array of pediatric polyposis syndromes, current screening recommendations, and surgical indications and technical considerations. Optimal disease management for these pediatric patients is still evolving and has implications for screening, surveillance, pediatric surgical management, and transition of care gastroenterologic neoplasia physicians and surgeons.

Paradoxical Impact of Ileal Pouch-Anal Anastomosis on Male and Female Fertility in Patients With Ulcerative Colitis

BACKGROUND

Birth rates in males with ulcerative colitis and ileal pouch-anal anastomosis have not been studied.

OBJECTIVE

This study aimed to estimate birth rates in males and females with ulcerative colitis and study the impact of ileal pouch-anal anastomosis.

DESIGN

This was a retrospective registry-based cohort study that was performed over a 30-year period.

SETTINGS

Records for parenting a child from the same period were cross-linked with patient records, and birth rates were calculated using 15 through 49 years as age limits. All data were prospectively registered.

PATIENTS

All patients with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis between 1980 and 2010 were identified in Danish national databases.

MAIN OUTCOME MEASURES

The primary outcomes measured were birth rates in females and males with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis.

RESULTS

We included 27,379 patients with ulcerative colitis (12,812 males and 14,567 females); 1544 had ileal pouch-anal anastomosis (792 males and 752 females). Patients with ulcerative colitis have slightly reduced birth rates (males at 40.8 children/1000 years, background population 43.2, females at 46.2 children/1000 years, background population 49.1). After ileal pouch-anal anastomosis, males had increased birth rates at 47.8 children/1000 years in comparison with males with ulcerative colitis without ileal pouch-anal anastomosis (40.5 children/1000 years), whereas females had reduced birth rates at 27.6 children/1000 years in comparison with females with ulcerative colitis without ileal pouch-anal anastomosis (46.8 children/1000 years).

LIMITATIONS

Only birth rates were investigated and not fecundability. Furthermore, there is a question about misattributed paternity, but this has previously been shown to be less than 5%.

CONCLUSIONS

Ulcerative colitis per se has little impact on birth rates in both sexes, but ileal pouch-anal anastomosis surgery leads to a reduction in birth rates in females and an increase in birth rates in males. This has clinical impact when counseling patients before ileal pouch-anal anastomosis surgery.

Optimizing Inflammatory Bowel Disease for Successful In Vitro Fertilization

We present a nulliparous woman with mild to moderate ulcerative colitis (UC) and multiple failed cycles of in vitro fertilization (IVF) in whom we achieved a successful, viable pregnancy following clinical and endoscopic UC remission. Infertile patients with inflammatory bowel disease who have failed multiple cycles of IVF should try to achieve clinical remission and mucosal healing (absence of erosions or ulcers) prior to reattempting conception. Furthermore, deficiencies in vitamin B12, vitamin D, and iron should be addressed.

Ongoing challenges and controversies in ulcerative colitis surgery

For patients with ulcerative colitis requiring surgery, surgical options include a total proctocolectomy with an end ileostomy and ileal pouch-anal anastomosis or a continent reservoir, or instead, a subtotal colectomy with an ileorectal anastomosis. The ileal pouch-anal anastomosis is currently considered the gold standard procedure that is employed in the majority of patients. Despite strong data supporting the feasibility, durability and the maintenance of long term functional outcomes and quality of life, certain controversies pertaining to its relative role, method of creation and effects on related pelvic structures remain a matter of debate.

Managing inflammatory bowel disease in pregnancy: current perspectives

Inflammatory bowel disease (IBD) affects many women of childbearing age. The course of IBD is closely related to pregnancy outcomes with poorly controlled IBD increasing the risk of prematurity, low weight for gestation, and fetal loss. As such, women with IBD face complex decision making weighing the risks of active disease versus those of medical treatments. This review summarizes the current evidence regarding the safety and efficacy of IBD treatments during pregnancy and lactation aiming to provide up-to-date guidance for clinicians. Over 50% of women have poor IBD- and pregnancy-related knowledge, which is associated with views contrary to medical evidence and voluntary childlessness. This review highlights the effects of poor patient knowledge and critically evaluates interventions for improving patient knowledge and outcomes.

What Factors Might Drive Voluntary Childlessness (VC) in Women with IBD? Does IBD-specific Pregnancy-related Knowledge Matter?

INTRODUCTION

Inflammatory Bowel Disease (IBD) affects many women of childbearing age, and rates of voluntary childlessness (VC) exceed those of the general population by far. The factors surrounding VC remain incompletely understood.

METHODS

Female members of the patient organisation Crohn's and Colitis UK aged 18-45 years were invited to complete an online questionnaire collecting data on demographics, disease characteristics, Crohn's and Colitis pregnancy-specific disease-related knowledge (CCPKnow), and childlessness status.

RESULTS

A total of 1324 women (mean age 33 years) completed the survey: 776 (59%) were diagnosed with Crohn's disease (CD), 496 (38%) with ulcerative colitis (UC) and 4% with inflammatory bowel disease-unclassified (IBD-U); 40% had children (14% pre-diagnosis (I); 26% post-diagnosis (II)), 36% planned to have children at some stage (III), 7% reported fertility problems (IV), and 17% were classified as voluntarily childless (VC). VC was associated with poorer CCPKnow scores [5.98 vs. 7.47 in (III); p < 0.001], older age [35 years old vs. 28 years old in (II); p < 0.001], unemployment (9.7% VC; p < 0.001), being single (34.5% VC; p < 0.001) not seeking medical advice (p < 0.001), and diagnosis of CD (19.3% vs. 13.9% UC; p = 0.015). Women with VC had more hospital admissions [mean 2.85 vs. 2.17 (III); p = 0.03] and surgical interventions [mean 1.27 vs. 0.65 (III); p < 0.001]

CONCLUSION

The aetiology of VC in women with IBD is multifactorial. Women's choice regarding children appears related to disease burden. VC is also associated with poor knowledge (CCPKnow), and women may stay childless unnecessarily. Patient education programmes could help to reduce the rate of VC in women with IBD, through correcting misconceptions and alleviating patient concerns.

Factors Associated with the Success of In Vitro Fertilization in Women with Inflammatory Bowel Disease

BACKGROUND

It is unknown whether certain factors are associated with the success of in vitro fertilization (IVF) in women with inflammatory bowel disease (IBD).

AIM

This study assessed whether certain characteristics are associated with greater success of live birth following IVF.

METHODS

In a cohort study of 8684 women with IBD seen at two tertiary care centers, we identified 121 women with IBD who underwent IVF. We assessed the effect of numerous factors on likelihood of achieving live birth after IVF.

RESULTS

Seventy-one patients with ulcerative colitis (UC) and 49 patients with Crohn's disease (CD) were analyzed. Patients with UC who achieved a live birth were younger (p = 0.03), had a shorter duration of disease (p = 0.01), and were more likely to be in remission (p = 0.03) versus those who did not achieve live birth. Patients with CD who achieved live birth were younger (p < 0.001), had lower body mass index (BMI) (p = 0.02), and had lower cycle day 3 follicle-stimulating hormone levels (p = 0.02). There was no difference in likelihood of achieving live birth among patients in remission and those with mild or unknown disease status (p = 0.69), though most CD patients (79.5 %) were in remission. Prior surgery was not associated with live birth in patients with UC (p = 0.31) or CD (p = 0.62).

CONCLUSIONS

As in the general infertility population, younger patients and those with lower BMI were more likely to achieve live birth. History of surgery was not associated with live birth among IBD patients. This is important information for practitioners counseling IBD patients.

Sexual satisfaction and inflammatory bowel diseases: an interdisciplinary clinical challenge

Inflammatory bowel diseases (IBD), most commonly Crohn's disease and ulcerative colitis, have the highest incidence during the reproductive years. IBD and its treatments increase the risk of sexual dysfunction for both men and women with these diseases. Women with IBD often seek care from their gynecologist and may preferentially discuss sexual experiences with them over other providers. An understanding of IBD and its impact on sexual functioning and satisfaction will improve screening, evaluation, and management for these patients. Identifying interdisciplinary providers for referrals, such as pelvic floor physical therapists and health psychologists, is a key component to long-term improvements in sexual satisfaction for women with IBD.

Female sexual function and fertility after ileal pouch-anal anastomosis

PURPOSE

A potential complication in women after ileal pouch-anal anastomosis (IPAA) is sexual impairment and reduced fertility. The aim was to evaluate sexual function and fertility after IPAA.

METHODS

All female patients who underwent an IPAA between 2004 and 2013 were retrospectively included. Sexual function, fertility, and continence were explored by the female sexual function index (FSFI), telephonic interview, and Wexner's score.

RESULTS

Among 127 women included, 93 responded to the questionnaires (73.2%). Seventy five were sexually active, and 48 (64%) had normal sexual function (FSFI > 26). In univariate analysis, there was a significant relationship between ulcerative colitis (p = 0.0161), age > 40 years (p = 0.01311), number of bowel movements (p = 0.0238), nocturnal pouch activity (p = 0.0094), use of loperamide (p = 0.0283), and existence of sexual dysfunction. After multivariate analysis, age and nocturnal pouch activity were associated with a worse sexual function (p = 0.0235, OR = 3.3 (1.2-9.9) and p = 0.0094, OR = 4.1 (1.4-13.5)). Of 16 patients who wished to have children, 10 (63%) became pregnant without recourse to in vitro fertilization, of whom 3 had two or more pregnancies. In total, there were 13 children born after IPAA. The mean time between the first pregnancy and surgery was 24.8 ± 22 months. At 12 and 24 months after cessation of contraception, 57 and 67% had at least one pregnancy.

CONCLUSIONS

While sexual function is impaired in a limited number of patients, the impact of surgery can be regarded as modest. Age and nocturnal pouch activity were some independent factors of worse sexual function. The risk of infertility should not preclude consideration of IPAA as a treatment option.

Treatment of the Pregnant Patient with Inflammatory Bowel Disease

Research regarding fertility, medication safety, and pregnancy outcomes is increasing, but there are still many knowledge gaps in these areas. Women with ulcerative colitis and Crohn's disease may have decreased fertility because of voluntary childlessness and inflammatory bowel disease (IBD) surgery, and women with Crohn's disease may also have decreased ovarian reserve. Initial studies show that in vitro fertilization is a viable option, and laparoscopic ileoanal pouch anastomosis surgery improves fertility rates. Additional research is needed on the effect of disease activity on fertility and on the rates of pregnancy loss and ectopic pregnancies. We do not know how to reliably measure disease activity during pregnancy or the effect of pregnancy on the microbiome. Although immunomodulators and anti-tumor necrosis factor medications are relatively safe during pregnancy, the long-term effects of these medications on the child are unknown. The recommended mode of delivery is still debated, especially for women after ileoanal pouch anastomosis. There are multiple studies on the relative safety of immunomodulators and anti-tumor necrosis factor medications during pregnancy, and we know how to safely treat a pregnant patient with a disease flare. The best way to manage women with IBD who are pregnant or contemplating pregnancy is a multidisciplinary approach. Team members often include a gastroenterologist, a high-risk obstetrician, an infertility specialist, a colorectal surgeon, and a pediatrician with experience in caring for children of mothers with IBD. By integrating expertise from these disciplines, women with even very complex IBD should be able to have a healthy pregnancy and delivery.

In Vitro Fertilization in Women With Inflammatory Bowel Disease Is as Successful as in Women From the General Infertility Population

BACKGROUND & AIMS

Inflammatory bowel disease (IBD) affects women of reproductive age, so there are concerns about its effects on fertility. We investigated the success of in vitro fertilization (IVF) in patients with IBD compared with the general (non-IBD) IVF population.

METHODS

We conducted a matched retrospective cohort study of female patients with IBD who underwent IVF from 1998 through 2011 at 2 tertiary care centers. Patients were matched 4:1 to those without IBD (controls). The primary outcome was the cumulative rate of live births after up to 6 cycles of IVF. Secondary outcomes included the proportion of patients who became pregnant and the rate of live births for each cycle.

RESULTS

Forty-nine patients with Crohn's disease (CD), 71 patients with ulcerative colitis (UC), 1 patient with IBD-unclassified, and 470 controls underwent IVF during the study period. The cumulative rate of live births was 53% for controls, 69% for patients with UC (P = .08 compared with controls), and 57% for patients with CD (P = .87 compared with controls). The incidence of pregnancy after the first cycle of IVF was similar among controls (40.9%), patients with UC (49.3%; P = .18), and patients with CD (42.9%; P = .79). Similarly, the incidence of live births after the first cycle of IVF was similar among controls (30.2%), patients with UC (33.8%; P = .54), and patients with CD (30.6%; P = .95).

CONCLUSIONS

Based on a matched cohort study, infertile women with IBD achieve a rate of live births after IVF that is comparable with those of infertile women without IBD.

Inflammatory bowel disease

Scandinavian researchers have contributed to the present understanding of inflammatory bowel disease (IBD). Important epidemiological data and family risk factors have been reported from all the Nordic countries, original twin studies mainly from Denmark and Sweden, and relationships to cancer and surgery mostly from Sweden. In collaboration with the industry, development of medical compounds was for a long time in the front line of international research, and the Scandinavian countries participated in the clinical breakthrough of biologic treatment. At present, many Nordic centers are working in the forefront of IBD research. An increasing number of young investigators have entered the scene along with the extended distribution of University clinics and research laboratories in these countries. This presentation of IBD gives a brief overview in the fields of clinical epidemiology and molecular biology. Many areas are covered by International collaborations with partners from Nordic centers. IBD was a topic focused by the founders of Scandinavian Journal of Gastroenterology. After 50 years one may state that the journal's history reflects important pieces of scientific knowledge within these diseases. The early scope of Johannes Myren for IBD was shown through his work in the original World Association of Gastroenterology (OMG), and after 50 years we can clearly support the view that global perspectives in IBD are increasingly important.

A reappraisal of the ileo-rectal anastomosis in ulcerative colitis

Colectomy is still frequently required in the care of ulcerative colitis. The most common indications are either non-responding colitis in the emergency setting, chronic active disease, steroid-dependent disease or neoplastic change like dysplasia or cancer. The use of the ileal pouch anal anastomosis has internationally been the gold standard, substituting the rectum with a pouch. Recently the use of the ileorectal anastomosis has increased in frequency as reconstructive method after subtotal colectomy. Data from centres using ileorectal anastomosis have shown the method to be safe, with functionality and risk of failure comparable to the ileal pouch anal anastomosis. The methods have different advantages as well as disadvantages, depending on a number of patient factors and where in life the patient is at time of reconstruction. The ileorectal anastomosis could, together with the Kock continent ileostomy, in selected cases be a complement to the ileal pouch anal anastomosis in ulcerative colitis and should be discussed with the patient before deciding on reconstructive method.

In Vitro Fertilization Is Successful in Women With Ulcerative Colitis and Ileal Pouch Anal Anastomosis

BACKGROUND

Women with ulcerative colitis (UC), who require ileal pouch anal anastomosis (IPAA), have up to a threefold increased incidence of infertility. To better counsel patients who require colectomy, we examined the success rates of in vitro fertilization (IVF) among women who have undergone IPAA.

METHODS

This was a retrospective cohort study conducted at the Brigham and Women's Hospital and Beth Israel Deaconess Medical Center. Female patients with UC were identified via ICD-9 codes and cross-referenced with those presenting for IVF from 1998 through 2011. UC patients with IPAA were compared with the following two unexposed groups that underwent IVF: (1) patients with UC, who had not undergone IPAA, and (2) patients without inflammatory bowel disease (IBD). The primary outcome was the cumulative live birth rate. Secondary outcomes included number of oocytes retrieved, proportion of patients who underwent embryo transfer, pregnancy rate, and live birth rate at first cycle.

RESULTS

There were 22 patients with UC and IPAA, 49 patients with UC and without IPAA, and 470 patients without IBD. The cumulative live birth rate after six cycles in the UC and IPAA groups was 64% (95% confidence interval (CI): 44-83%). This rate did not differ from the cumulative live birth rate in the UC without IPAA group (71%, 95% CI: 59-83%; P=0.63) or the group without IBD (53%, 95% CI: 48-57%; P=0.57).

CONCLUSIONS

This study demonstrates that in our cohort, women who undergo IPAA achieve live births following IVF at comparable rates to women with UC without IPAA and to women without IBD.

Menstrual cycle, sex hormones in female inflammatory bowel disease patients with and without surgery

Healthy women at reproductive age experience a cyclical alteration of gastrointestinal (GI) symptomatology during their menstrual cycle. Additionally, the majority of healthy women also complain of worsening of GI symptoms either during the premenstrual or menstrual phase. Despite conflicting evidence, studies suggest that sex hormones may increase GI transit time during the luteal phase. Similar phenomenon is also observed in women with underlying inflammatory bowel disease (IBD). The mechanism underlying this complex pathophysiology is still not completely understood. However, a possible influence of sex hormones on the brain-gut-microbiota axis is hypothesized. The diagnosis of IBD is associated with a delay in menarche as well as menstrual function irregularities including alterations in cycle length and the duration of flow. There is little data on the effect of menopause on IBD disease activity and conflicting data on the effect of IBD diagnosis on the onset of menopause. The role of contraceptives and hormone replacement therapies on the development or disease activity of IBD has not been yet established. Moreover, IBD patients with concomitant dysmenorrhea report heightened pain during menses. The effect of non-steroidal anti-inflammatory drugs in treating primary dysmenorrhea on the disease course of IBD is unknown. In addition, the effect of IBD medications including immunomodulators and biologics on menstrual function remains unclear. Also, the role of IBD surgery on menstrual irregularities needs to be fully elucidated. Hence, understanding the influence of menstrual function on IBD disease activity and vice versa and the maintenance of normal menstrual function in those patients is important in improving overall reproductive health and fertility and outcome of IBD.

Toxic megacolon during pregnancy in ulcerative colitis: A case report

•

Ulcerative colitis has a peak incidence which coincides with the childbearing age of females.

•

Acute fulminant colitis during pregnancy is rare, but requires mandatory surgical colectomy which carries a significant risk to both mother and fetus.

•

We recommend that female patients planning to conceive with a known diagnosis of ulcerative colitis have an optimised medical regimen by liaising with their obstetricians and gastroenterologists to prevent exacerbations and the development of toxic megacolon.

•

Should surgical intervention become required, this can be performed with favourable outcomes for mother and child as demonstrated in this report.

Introduction

Ulcerative colitis is an idiopathic inflammatory bowel condition whose peak incidence coincides with fertility in female patients. In pregnancy, acute fulminant colitis is rare, and, when it becomes refractory to maximum medical therapy, emergency colectomy is mandated. Over the past quarter century, there have been few reports of this rare event in the literature.

Presentation of case

We report a 26 year old primigravida female who presented with toxic megacolon during the third trimester of pregnancy, unresponsive to medical therapy. She subsequently underwent an urgent low transverse caesarean section with a total colectomy. Both mother and child made a satisfactory recovery post operatively.

Discussion

Although the fetus is at higher risk than the mother in such a circumstance, morbidity and mortality rates are still noticeably high for both, and therefore, prompt diagnosis is key.

Conclusion

It is imperative that female patients planning to conceive with a known diagnosis of ulcerative colitis liaise with their obstetricians and gastroenterologists early to optimise medical treatment to prevent the development of a toxic megacolon and that conception is planned during a state of remission. Should surgical intervention become required, this can be performed with favourable outcomes for mother and child, as demonstrated in this report.
