Pregnancy outcome following non-obstetric surgical intervention

Safe laparoscopic appendectomy in pregnant patient during active labor

Appendectomy is the standard of care in pregnant patients with acute appendicitis. The use of laparoscopy in pregnant patients with acute appendicitis is still debated, especially for patients in their third trimester. We present a case of a patient who safely underwent a laparoscopic appendectomy during early labor and subsequently delivered a healthy baby. In the correct situations and hands, laparoscopy can likely be safely used throughout pregnancy.

Clinical presentation and management of urolithiasis in the obstetric patient: a matched cohort study

PURPOSE

To evaluate the effect of pregnancy on the clinical presentation, inpatient procedure rates, and length of hospital stay, on women with urolithiasis.

MATERIALS AND METHODS

We carried out a matched cohort study using the United States' Healthcare Cost and Utilization Project-Nationwide Inpatient Sample database from 1999 to 2015. Pregnant women with urolithiasis were compared to age-matched non-pregnant women (1:1) with urolithiasis. Baseline clinical characteristics were compared between the two cohorts and the effect of pregnancy on select inpatient procedural and clinical outcomes was evaluated using conditional logistic regression models.

RESULTS

There were 42,113 pregnant patients diagnosed with urolithiasis during the study period. It was observed that pregnant patients were less likely to present with classic clinical symptoms of urinary tract stones, such as flank pain, OR 0.63, 95% CI 0.56-0.70, and fever, 0.22 (0.16-0.30), but tended to have longer hospital stays. The pregnant patients were less commonly affected by infectious conditions, namely urinary tract infections, 0.56 (0.53-0.59), sepsis, 0.17 (0.14-0.20), and pyelonephritis, 0.34 (0.36-0.44). Invasive and surgical procedures were less commonly performed in pregnant women.

CONCLUSIONS

Pregnant women admitted with urolithiasis appear to be less symptomatic with fewer interventions and complications than non-pregnant women with urolithiasis.

Postoperative complications after non-obstetric surgery among pregnant patients in the National Surgical Quality Improvement Program, 2005-2012

BACKGROUND

To examine whether pregnant patients have higher risk of major 30-day postoperative complications compared with their non-pregnant counterparts after non-obstetric surgery.

METHODS

A secondary analysis of the prospective National Surgical Quality Improvement Program (NSQIP) from 2005 to 2012 of pregnant patients 18-51 years old, without surgery in the preceding 30 days, and who underwent a non-obstetrical operation. The primary outcome was composite 30-day major postoperative complications. We used modified Poisson regression.

RESULTS

Among 354,251 assessed patients, 3655 (1%) were pregnant. The overall incidence of 30-day major postoperative complication was 6%, and did not vary by pregnancy status. Pregnant patients were not at higher risk of 30-day major postoperative complications compared to non-pregnant patients following non-obstetric surgery. This held for most procedures, except pregnant patients were at a higher risk of complications with colorectal and hernia surgeries. Secondarily, pregnant patients were at higher risk of transfusion.

CONCLUSIONS

Pregnant patients are generally not at higher risk of major postoperative complications following non-obstetric surgery. This information can be used when counseling pregnant patients about the risks versus benefits of non-obstetric surgery.

[Breast cancer and pregnancy: about 15 cases collected at the maternity center Monastir, Tunisia]

Le but de cette étude était de décrire les caractéristiques cliniques, radiologiques, histologiques et thérapeutiques du cancer du sein diagnostiqué au cours de la grossesse. Nous avons effectué la revue de tous les cancers du sein diagnostiqués au cours de la grossesse dans le centre Maternité et de Néonatologie de Monastir -Tunisie, sur une période allant de 2004 à 2019. Nous avons ainsi colligé 15 cas. L'âge moyen des patientes était de 34 ans. La plupart des cancers du sein associés à la grossesse (CSAG) était diagnostiquée en post-partum. Le carcinome canalaire infiltrant était le type histologique majeur (93% de cas), un cas rare de carcinome sécrétoire a été observé. Le stade clinique était dominé par les formes T2 et T4. Les récepteurs hormonaux étaient négatifs dans 40% des cas, le récepteur HER2 était positif dans 26,6% des cas. Le traitement incluait la chirurgie, radiothérapie, chimiothérapie et palliative. La moyenne de survie est de 32,2 mois. Le cancer du sein associé à la grossesse est une entité rare. Son pronostic est globalement mauvais en raison de l'âge jeune de survenue et d´un diagnostic souvent tardif. La décision thérapeutique constitue une contrainte difficile, par nécessité, multidisciplinaire à laquelle participera la patiente. La thérapie ciblée reste le grand espoir des nouvelles thérapies.

Evaluation of safety and foeto-maternal outcome following non-obstetric surgery in pregnancy: a retrospective single-site Australian study

BACKGROUND

Existing data on safety of non-obstetric surgery during pregnancy appear limited and conflicting. This study aimed to assess perinatal outcomes and complications in pregnant women undergoing non-obstetric surgeries.

METHODS

A single-site Australian study was performed utilizing a 10-year data (2009-2018) collected retrospectively. Descriptive statistics were used to summarize the characteristics of the study population. Statistical analyses between groups were conducted by independent t-test or Mann-Whitney (for means between groups) and by chi-squared/Fisher's exact test (for categorical variables).

RESULTS

A total of 108 pregnant women underwent non-obstetric surgery, with an increasing trend in annual numbers since 2014. The majority of women (91%) underwent surgeries as an emergency procedure, and under general anaesthesia (69.8%). Procedures during the first trimester comprised 45%, making it the most common trimester for non-obstetric surgeries. The most common cause for surgery arose in the gastrointestinal/digestive tract (39%). Overall perinatal complication rate was 19% with the rate of miscarriage/foetal loss, preterm birth and intrauterine growth restriction/small for gestational age being 4.7%, 10.4% and 3.8%, respectively. A total of 46 patients underwent intra-abdominal surgery. The most common surgery in the laparoscopy group was appendicectomy (56%), whereas adnexal pathology (54%) contributed to the majority of laparotomies. Subgroup comparison showed no significant difference in perinatal outcomes except for caesarean delivery rate (24% versus 67% for laparoscopy versus open, respectively (P = 0.04)).

CONCLUSION

With an overall perinatal complication rate of 19%, the rate of adverse perinatal outcomes following non-obstetric surgery during pregnancy in our study was low and comparable to those of the general population.

Masson's tumor presenting as a left frontal intraparenchymal hemorrhage resulting in severe expressive aphasia during pregnancy: case report

Intravascular papillary endothelial hyperplasia (IPEH), commonly known as Masson's tumor, is a benign lesion that manifests as an excessive proliferation of endothelial cells within a vessel wall. IPEH is extremely rare in the brain, with only 36 intracranial cases previously described in the literature. It is commonly mistaken for more malignant pathologies, such as angiosarcoma. Careful histopathological examination is required for diagnosis, as no clinical or radiographic features are characteristic of this lesion. In this first published case of intracranial IPEH presenting during pregnancy, the authors describe a 32-year-old female with a left frontal intraparenchymal hemorrhage resulting in complete expressive aphasia at 28 weeks 6 days' gestation. An MRI scan obtained at a local hospital demonstrated an area of enhancement within the hemorrhage. The patient underwent a left frontoparietal craniotomy for hematoma evacuation and gross-total resection (GTR) of an underlying hemorrhagic mass at 29 weeks' gestation. This case illustrates the importance of multidisciplinary patient care and the feasibility of intervention in the early third trimester with subsequent term delivery. While GTR of IPEH is typically curative, the decision to proceed with surgical treatment of any intracranial lesion in pregnancy must balance maternal stability, gestational age, and suspected pathology.

Update on the Management of Breast Cancer during Pregnancy

The diagnosis of breast cancer during pregnancy represents a challenging situation for the patient, her caregivers and physicians. Pregnancy adds complexity to oncological treatment planning, as many therapies can be potentially dangerous to the fetus. Therefore, a multidisciplinary approach is needed to offer a proper care for obtaining the best possible outcomes for the mother and the future child. Breast surgery is feasible throughout the pregnancy while radiotherapy should be postponed after delivery. Administration of chemotherapy is considered safe and can be given during the second and third trimesters, while it is contraindicated in the first trimester due to the high risk of fetal malformations. Endocrine therapy and targeted agents are not recommended during the whole pregnancy period; however, limited data are available on the use of the majority of new anticancer drugs in this context. The aim of the current review is to provide an update on the current state of art about the management of women diagnosed with breast cancer during pregnancy.

A Review of the Neurosurgical Management of Brain Metastases During Pregnancy

OBJECTIVE

Patients with pregnancy-associated secondary brain tumors (PASBT) are challenging to manage. Because no guidelines for the management of such patients currently exist, we performed a systematic review of the literature using PRISMA guidelines with a discussion of management from a neurosurgeon's perspective.

METHOD

Systematic review of the literature using PRISMA guidelines from 1999 to 2018.

RESULTS

We identified 301 studies of which 16 publications (22 patients reporting 25 pregnancies, 20 deliveries, 5 early terminations) were suitable for final analysis. The most frequent primary cancers were breast (8/22, 36.36%), skin (6/22, 27.27%), and lung (5/22, 22.73%). Four patients (18.18%) had neurosurgical procedures during their pregnancies. Five patients (22.73%) received neurosurgical resection after their pregnancies. Nine patients (40.91%) received radiation therapy and seven patients (31.82%) received chemotherapy during pregnancy while seven patients (31.82%) received chemotherapy and radiation after pregnancy. There was 1 fetal death (5%) out of 20 healthy deliveries. Five pregnancies (20%) were terminated in the first trimester due to a need for urgent neurosurgical intervention.

CONCLUSION

Management of PASBT remains a challenging issue. Maternal and fetal risks associated with surgical resection and teratogenicity due to adjuvant therapy should be discussed in the context of a multidisciplinary team. Timing of surgery and the use of systemic chemoradiation depends on the gestational age (GA) of the fetus, extent, and control of the mother's primary and metastatic disease. Guidelines need to be established to help neuro-oncology teams safely and effectively manage this group of patients.

Management Challenges of Metastatic Spinal Cord Compression in Pregnancy

Primary and secondary spinal tumours with cord compression often represent a challenging condition for the patient and clinicians alike, even more so during pregnancy. The balance between safe delivery of a healthy baby and management of the mother's disease bears many clinical, psychological, and ethical dilemmas. Pregnancy sets a conflict between the optimal surgical and oncological managements of the mother's tumour and the well-being of her foetus. We followed the CARE guidelines from the EQUATOR Network to report an exemplificative case of a 39-year-old woman with a 10-year history of breast cancer, presenting in the second trimester of her first pregnancy with acute onset severe thoracic spinal instability, causing mechanical pain and weakness in lower limbs. Neuroradiological investigations revealed multilevel spinal deposits with a pathological T10 fracture responsible for spinal cord compression. The patient was adamant that she wanted a continuation of the pregnancy and her baby delivered. After discussion with her oncologist and obstetrician, we agreed to perform emergency spinal surgery—decompression and instrumented fixation. The literature search did not reveal a similar case of spinal metastatic breast cancer undergoing spinal instrumentation and delivery of a healthy baby a few months later. Following the delivery, the patient had further oncological treatment, including chemotherapy and radiotherapy. The paucity of such reports prompted us to present this case and highlight the relevance of a multidisciplinary approach involving obstetrician, oncologist, spinal surgeon, and radiologist to guide the optimal decision-making process.

A ten-year, single institution experience with percutaneous nephrostomy during pregnancy

PURPOSE

To evaluate the safety and efficacy of percutaneous nephrostomy (PCN) in pregnancy.

MATERIALS AND METHODS

PCN tubes were placed during 52 pregnancies in 49 patients from 2008 to 2018. The medical records during pregnancies were retrospectively reviewed for imaging findings, procedural parameters, outcomes of delivery, and complications.

RESULTS

The mean gestational age on percutaneous nephrostomy placement was 27 weeks (range, 8-36 weeks). PCN catheters were placed for the following indications: 1) flank or lower abdominal pain (42%), 2) obstructing calculi (37%), 3) pyelonephritis (20%), and 4) obstructing endometrioma (2%). Prior to PCN, retrograde ureteric stenting was performed in 17 of 49 patients (34%) and attempted but failed in 4 patients (8%). Nephrostomy drainage relieved pain completely or significantly in all 12 patients without prior ureteral stenting, but in only 4 of 10 with retrograde ureteric stents. In one patient in whom the ureteral stent had been removed, PCN relieved her flank pain. The mean number of PCN catheter exchanges was 1.6, ranging from 0 to 9, with a mean time interval of 21.3 days between exchanges. There were 29 difficult exchanges due to encrustation in 15 patients with a mean of 20.5 days between exchanges.

CONCLUSIONS

PCN drainage is a safe and effective treatment for managing symptomatic hydronephrosis in pregnant patients but is less effective in treating pain when retrograde ureteral stents are in place. Rapid encrustation, seen more commonly in pregnancy, tends to recur in the same patients and requires more frequent exchanges than the general population.

Perioperative care of the pregnant patient undergoing non-obstetric surgery

There are a number of challenges associated with the pregnant patient undergoing non-obstetric surgery. Careful assessment and planning, taking into account the physiological and anatomical changes, will allow for optimal perioperative management.

Diagnosis and management of gastric cancer in pregnancy-An evidence-based case report

BACKGROUND

Gastric cancer in pregnancy is a very rare case with an incidence of 0.016% and is mostly detected in a locally advanced or advanced stage due to misinterpretation of non-specific signs and symptoms. Management of gastric cancer in pregnancy should emphasize mother and fetal survival. Currently, there is no diagnostic and management guidance for gastric cancer in pregnancy. The purpose of this study is to ascertain how to diagnose and manage gastric cancer in pregnancy.

METHODS

This study is an evidence-based case report performed in Digestive Division of Department of Surgery in Cipto Mangunkusumo hospital in September-October 2017. Literature search on databases such as Cochrane, PubMed, ScienceDirect, and Scholar Google used keywords like "gastric cancer" AND "pregnant" OR "pregnancy" with inclusion criteria which are systematic review, randomized-clinical trial (RCT), cohort study, case report, or case series, performed in human and published in the last 10 years in English language. Critical appraisal is done according to Oxford Centre For Evidence-Based Medicine 2011. This work is reported in line with the SCARE criteria.

RESULTS

There are 9 case-report studies and 1 case-control study. Radiology examination includes endoscopy, MRI, and CT scan. Management is given according to cancer stage which is; surgery, surgery with adjuvant therapy, and palliative chemotherapy.

CONCLUSION

Radiology examinations with a lower risk of adverse effects are endoscopy and MRI. CT scan may be performed when the benefits exceed the risk. Surgery and chemoradiation have the lowest rate of adverse effects when done in the second and third trimester.

Lymphoma Occurring During Pregnancy: Current Diagnostic and Therapeutic Approaches

PURPOSE OF REVIEW

Pregnancy-associated lymphoma (PAL) is an uncommon entity that lacks detailed prospective data. It poses significant management challenges that incorporate maternal and fetal risks associated with treatment or delayed intervention. Herein, we review the current literature for the diagnosis, management, and supportive care strategies for PAL.

RECENT FINDINGS

Establishment of a multidisciplinary team, including hematology-oncology, maternal-fetal medicine, and neonatology, is critical in the management of PAL. For staging, ultrasound and MRI are preferred modalities with use of computerized tomography in select situations. Data for the safety and effectiveness of therapy for PAL is largely based on retrospective studies. The timing of lymphoma-directed antenatal systemic therapy depends on the trimester, gestational age, lymphoma subtype and aggressiveness, and patient wishes. Therapy in the first trimester is usually not advocated, while treatment in the second and third trimesters appears to result in similar outcomes for PAL compared with non-pregnant patients with lymphoma. An overarching goal in most PAL cases should be to plan for delivery at term (i.e., gestational age > 37 weeks). For supportive care, most antiemetics, including agents such as neurokinin-1 receptor antagonists, have been used safely during pregnancy. For prevention or treatment of infections, particular antibiotics (i.e., macrolides, cephalosporins, penicillins, metronidazole), antivirals (i.e., acyclovir, valacyclovir, famciclovir), and antifungals (amphotericin B) have demonstrated safety and with use of growth factors reserved for treatment of neutropenia (vs. primary prophylaxis). Therapy for PAL should be individualized with goals of care that balance maternal and fetal well-being, which should include a multidisciplinary care team and overall intent for term delivery in most cases.

Laparoscopic appendectomy is safe and feasible in pregnant women during second trimester: A retrospective study in a top-level Chinese center

Acute appendicitis (AA) is the most common nonobstetric surgical emergency during pregnancy. According to the current guidelines and meta-analyses, traditional open appendectomy (OA) is still recommended for pregnant patients over laparoscopic appendectomy (LA), which might be associated with higher rates of fetal loss. Previous studies and experiences indicated that LA might be safe in the second trimester of pregnancy. The current study aimed to evaluate the safety and feasibility of LA in pregnant women during the second trimester.At our institution, a retrospective study was conducted with pregnant patients who underwent LA or OA during the second trimester between January 2016 and August 2018.A total of 48 patients were enrolled. Of them, 12 were managed with laparoscopy and 36 with the open approach. We found that the LA group had higher BMIs than the OA group (4.0 ± 4.3 vs 21.5 ± 2.9, P = .031). The financial results showed that the average daily medical costs for patients who underwent LA was higher than those who underwent OA (444 ± 107 US$ vs 340 ± 115 US$, P = .009), while the total cost of hospitalization was comparable between the 2 approaches. The perioperative and obstetric outcomes were comparable between LA and OA. In each group, only 1 patient had fetal loss. No "Yinao" was found in any of the patients in the LA group.In this study, with the proven advantages of the laparoscopic techniques, LA was found to be safe and feasible for pregnant women during the second trimester.

Maternal and fetal cardiovascular and metabolic effects of intra-operative uterine handling under general anesthesia during pregnancy in sheep

A cohort study of 6,500,000 human pregnancies showed an increased risk of adverse fetal outcomes following abdominal but not non-abdominal surgery under general anesthesia. This may be the consequence of uterine handling during abdominal surgery. However, there are no data on any effects on the cardiometabolic physiology of the fetus or mother in response to uterine manipulation in otherwise healthy pregnancy. Consequently, 9 sheep in late gestation were anesthetized with isofluorane and maternal and fetal catheters and flow probes were implanted to determine cardiovascular and metabolic changes during uterine handling. Uterine handling led to an acute increase in uterine artery vascular resistance, fetal peripheral vasoconstriction, a reduction in oxygen delivery to the femoral circulation, worsening fetal acidosis. There was no evidence of systemic fetal hypoxia, or changes in fetal heart rate, carotid blood flow or carotid oxygen delivery. Therefore, the data support that uterine handling during abdominal surgery under general anesthesia can impact adversely on fetal cardiometabolic health. This may provide a potential explanation linking adverse fetal outcomes in abdominal compared with non-abdominal surgery during pregnancy. The data have important implications for human fetal surgery where the uterus is handled, as operative procedures during late gestation under general maternal anesthesia become more prevalent.

Evidence-Based Management of Calculous Biliary Disease for the Acute Care Surgeon

Background: Gallstones and cholecystitis are common clinical problems. There is a wide spectrum of disease severity, from rare symptoms of biliary colic to severe cholecystitis with marked gallbladder infection and inflammation that can cause life-threatening sepsis. The care of such patients is similarly varied and multi-disciplinary. Despite the prevalence of cholecystitis, there remain questions about how to manage patients appropriately. Methods: A multi-disciplinary team created institutional cholecystitis guidelines, and supporting evidence was compiled for review. Results: Even in "routine" cholecystitis, patient triage and work-up can be variable, resulting in unnecessary tests and delay to cholecystectomy. Beyond this, there are new treatment options available that may serve special populations particularly well, although the appropriate pattern of emerging endoscopic and percutaneous treatment modalities is not well defined. Conclusions: This review outlines evidence-based management of cholecystitis from diagnosis to treatment with a focused discussion of special populations and emerging therapies.

The American Association of Endocrine Surgeons Guidelines for the Definitive Surgical Management of Thyroid Disease in Adults

OBJECTIVE

To develop evidence-based recommendations for safe, effective, and appropriate thyroidectomy.

BACKGROUND

Surgical management of thyroid disease has evolved considerably over several decades leading to variability in rendered care. Over 100,000 thyroid operations are performed annually in the US.

METHODS

The medical literature from 1/1/1985 to 11/9/2018 was reviewed by a panel of 19 experts in thyroid disorders representing multiple disciplines. The authors used the best available evidence to construct surgical management recommendations. Levels of evidence were determined using the American College of Physicians grading system, and management recommendations were discussed to consensus. Members of the American Association of Endocrine Surgeons reviewed and commented on preliminary drafts of the content.

RESULTS

These clinical guidelines analyze the indications for thyroidectomy as well as its definitions, technique, morbidity, and outcomes. Specific topics include Pathogenesis and Epidemiology, Initial Evaluation, Imaging, Fine Needle Aspiration Biopsy Diagnosis, Molecular Testing, Indications, Extent and Outcomes of Surgery, Preoperative Care, Initial Thyroidectomy, Perioperative Tissue Diagnosis, Nodal Dissection, Concurrent Parathyroidectomy, Hyperthyroid Conditions, Goiter, Adjuncts and Approaches to Thyroidectomy, Laryngology, Familial Thyroid Cancer, Postoperative Care and Complications, Cancer Management, and Reoperation.

CONCLUSIONS

Evidence-based guidelines were created to assist clinicians in the optimal surgical management of thyroid disease.

Management of a rhegmatogenous retinal detachment in a pregnant patient

Purpose

To describe the management of a rhegmatogenous retinal detachment (RRD) in a pregnant patient.

Observations

A 30-year-old, 26-week pregnant female presented with curtain vision loss in the left eye. Exam findings were significant in the left eye for an inferior fovea-sparing RRD. Care was coordinated and discussed with anesthesia and OB/GYN. The patient underwent surgery with monitored anesthesia care and a 41 scleral buckle, cryotherapy and C3F8 gas. The retina remained attached at 4 months post-operatively. A healthy girl was delivered via spontaneous vaginal delivery at 39 weeks.

Conclusion

Safe and successful treatment of RRD in pregnant patients can be achieved with careful coordination between ophthalmology, anesthesia, and obstetrics. An understanding of pregnancy specific considerations is important in order to optimize patient outcomes.

Factors Affecting Maternal and Fetal Outcomes of Non-Obstetric Surgery and Anesthesia during Pregnancy: a Retrospective Review of Data at a Single Tertiary University Hospital

BACKGROUND

Anesthesia during pregnancy for non-obstetric surgery is generally known to have a negative impact on maternal and fetal outcomes. We assessed the risk of adverse outcomes in fetuses and mothers associated with non-obstetric surgery.

METHODS

This retrospective study analyzed clinical data on pregnant women who received non-obstetric surgeries at a tertiary university hospital. We reviewed maternity admissions using hospital administrative data during the last 16 years. The outcome assessment included the presence of preterm labor, premature birth, abortion, or stillbirth and the data of newborns. Statistical analyses were performed using the t-test, χ² test, and multiple logistic regression was used for risk analysis.

RESULTS

The incidence of non-obstetric surgery during pregnancy was 0.96%. Gestational age at or above 20 weeks increased the risk of all adverse events 4.5 fold when it was compared to gestational age less than 20 weeks, although the events were only preterm labor or premature birth and no fetal loss. All fetal loss cases occurred in patients at less than 20 weeks of pregnancy. The risk of adverse outcome increased by 2% for every 1 minute increase in anesthesia time. Babies of the mothers who had the adverse outcome event showed lower birth weight and higher neonatal intensive care unit admission rate than those of babies of the mothers without any adverse event after the surgery.

CONCLUSION

Physicians should acknowledge and prepare for common possible adverse events at the stage of pregnancy after non-obstetric surgery, and effort to shorten the duration of surgery and anesthesia is needed.

Clinical management of the pregnant patient undergoing non-obstetric surgery: Review of guidelines

The management principles of non-obstetric surgery during pregnancy are important concepts for all health care providers to be cognizant of. The goals of non-obstetric surgery are to ensure maternal safety, maintain the pregnancy, and ensure fetal well-being. In this regard, organogenesis occurs roughly between days 7-57 and thus, certain medications have a higher incidence of fetal teratogenicity in this first trimester. Some examples of common surgeries performed urgently or emergently include appendectomies, ovarian detorsions, bowel obstruction, trauma, and cholecystectomies. The choice of anesthetic technique and the selection of appropriate anesthetic drugs should be guided by indication for surgery, the nature of the surgery, and the site of the surgical procedure. Many of the concerns for any patients undergoing urgent or emergent surgery must be considered by anesthesia providers along with steps to ensure the fetus has the best outcome.

Surgical indications for pituitary tumors during pregnancy: a literature review

PURPOSE

Surgical indications for pituitary tumors during pregnancy are rare, and are derived from a balance between expected benefits, particularly for maternal benefits, and anesthetic/surgical risks.

METHODS

A literature review was performed to define the optimal surgical indications for pituitary adenomas (PA) and other pituitary tumors during pregnancy.

RESULTS

Main benefits are expected in case of critical visual impairment and/or life-threatening endocrine disturbances. Multidisciplinary patient management is systematically required although nonobstetric surgery presents a reasonable risk during pregnancy. The risks of congenital malformation during the first trimester and those of premature birth during the third trimester make the second trimester the optimal period for surgery. In prolactin-secreting, nonsecreting, GH- and TSH-secreting PAs, transsphenoidal surgery (TS) is recommended in cases involving severe visual impairment, characterized by severe visual field deficit, visual acuity impairment, and abnormal optical coherence tomography findings, and when no other medical alternatives are possible and/or sufficient. Uncontrolled and severe Cushing's disease (CD) during pregnancy increases both maternal and fetal morbimortality, thus justifying TS or sometimes dopamine agonist therapy as a safer alternative. Finally, metyrapone, ketoconazole, or bilateral adrenalectomy could be recommended in certain cases after the failure of medical therapies and/or TS. Surgery is also required for suprasellar meningiomas, craniopharyngiomas, and pituitary cysts in the case of severe visual deficit.

CONCLUSION

Surgical indications for pituitary tumors are rare during pregnancy; therefore, surgery should be avoided when possible. Further, the second trimester should be considered as the optimal surgical period. Severe visual disturbance and uncontrolled CD are the main surgical indications during pregnancy.

Factores pronóstico asociados a parto prematuro en mujeres sometidas a apendicectomía durante el embarazo en un país de medianos ingresos

Introducción. El objetivo del estudio fue estimar los factores pronóstico asociados con el parto prematuro y otros resultados clínicos en mujeres embarazadas sometidas a apendicectomía en Colombia. Métodos. Se llevó a cabo un estudio retrospectivo de cohorte a partir de las bases de datos administrativos, que incluyó mujeres embarazadas afiliadas al sistema de salud contributivo en Colombia y sometidas a apendicectomía, entre enero de 2013 y noviembre de 2016. Se estimaron la tasa de parto prematuro, la tasa de mortalidad a los 30 días, el ingreso materno a la unidad de cuidados intensivos a 30 días, el reingreso de la madre a los 30 días y el bajo peso al nacer. Se utilizaron regresiones logísticas multivariadas para identificar estos tres factores pronóstico. Resultados. Se incluyeron 1.589 mujeres en el estudio. La edad media fue de 26,43 ± 5,79 años, el 17,94 % de las apendicectomías se practicaron en el tercer trimestre, el 6,10 % fueron apendicectomías laparoscópicas y el 22,03 % requirió drenaje por peritonitis. Las tasas de parto prematuro, mortalidad a 30 días, ingreso a la unidad de cuidados intensivos a 30 días, reingreso a los 30 días y bajo peso al nacer, fueron 12,08 %, 0,13 %, 9,75 %, 16,93 % y 3,34 %, respectivamente. La edad menor de 18 años, la apendicectomía en el tercer trimestre y el drenaje por peritonitis se asociaron con un mayor riesgo de parto prematuro. El índice de comorbilidad de Charlson, la apendicectomía en el tercer trimestre y el drenaje por peritonitis, se asociaron con un mayor ingreso materno a la unidad de cuidados intensivos. Conclusiones. La apendicectomía en el tercer trimestre y la apendicitis complicada, son factores pronóstico asociados a parto prematuro en mujeres colombianas embarazadas sometidas a apendicectomía.

Indirect bypass for maternal symptomatic moyamoya in the first trimester of pregnancy: case report

There are no practice guidelines for the treatment of moyamoya disease in pregnant women. The need for such guidelines, however, is evidenced by the numerous case reports, case series, and systematic reviews in the literature highlighting an at-risk period for female moyamoya patients of childbearing age. Here the authors review and interpret the existing literature as it applies to their index patient and expand the literature in support of treating select patients during pregnancy. The authors describe what is to their knowledge the first case reported in the literature of a patient successfully treated with indirect surgical revascularization during the first trimester, who went on to deliver a healthy term baby without complications.

Non-obstetric abdominal surgery during pregnancy and birth outcomes: A Danish registry-based cohort study

INTRODUCTION

Surgery during pregnancy may increase the risk of adverse birth outcomes. In this nationwide registry-based cohort study including women aged 15-54 years with singleton birth or miscarriage, we examined the association between non-obstetric abdominal surgery during pregnancy and the birth outcomes small-for-gestational-age (SGA), preterm birth, and miscarriage.

MATERIAL AND METHODS

The study used data on births or miscarriages from the large national Danish registries in 1997-2015. We calculated absolute risks and risk differences for the main outcomes and used Cox regression analysis with non-obstetric abdominal surgery as a time-varying exposure, adjusting for maternal age, year of last menstrual period, major abdominal surgery before pregnancy, maternal smoking status, rheumatoid arthritis, diabetes and inflammatory bowel disease. Our main outcome measures were risks and hazard ratios (HRs) for SGA, very preterm or preterm birth, and miscarriage after gestational week 7 overall, stratified by calendar year, and, for SGA, trimester of pregnancy. Finally, absolute risk of miscarriage stratified by time since surgery.

RESULTS

Absolute risks in surgically treated vs untreated were 3.4% vs 2.7% for SGA (adjusted HR 1.3, 95% CI 1.1-1.5), 2.2% vs 0.8% for very preterm birth (adjusted HR 2.8, 95% CI 2.2-3.5), 8.3% vs 4.3% for preterm birth (adjusted HR 2.1, 95% CI 1.9-2.3), and 8.2% vs 6.1% for miscarriage (adjusted HR 3.1, 95% CI 2.7-3.5). For miscarriage, the risk was highest the first week after surgery and levelled out after 2 weeks.

CONCLUSIONS

Surgery during pregnancy is associated with an increased risk of SGA, very preterm birth, preterm birth and miscarriage, and the risk of miscarriage is highest the first week after surgery.

Breast Cancer during Pregnancy-Current Paradigms, Paths to Explore

Breast cancer is the most common form of malignancy in pregnant women. The prevalence of pregnancy-associated breast cancer (PABC) is up to 0.04% of pregnancies and is expected to rise in developed countries. PABC represents a unique clinical scenario which requires a delicate balance of risks and benefits for both maternal and fetal well-being. Currently, there is paucity of data regarding the short- and long-term outcomes of in-utero exposure to anti-neoplastic agents. In general, when possible, treatment for PABC should follow the same guidelines as in non-pregnant patients. Surgery, including sentinel lymph node biopsy, is possible during all trimesters of pregnancy. Radiotherapy is contraindicated during pregnancy, although it might be considered in highly selected patients based on risk-benefit assessment. Evidence supports that administration of chemotherapy may be safe during the second and third trimesters, with cessation of treatment three weeks prior to expected delivery. Currently, hormonal therapy and anti-HER2 agents are contraindicated during pregnancy and should be postponed until after delivery. Prematurity is associated with worse neonatal and long-term outcomes, and thus should be avoided. While current data on the long-term effects of anti-neoplastic treatments are reassuring, grade of evidence is lacking, hence additional large prospective studies with long-term follow-up are essential to rule out any treatment-induced adverse effects.

Maternal surgery during pregnancy has a transient adverse effect on the developing fetal rabbit brain

BACKGROUND

Recently, the US Food and Drug Administration called for cautious use of anesthetic drugs during pregnancy. In 0.2-2% of pregnancies, nonobstetric surgery is being performed. The consequences of anesthesia during pregnancy on fetal development remain unclear, and preclinical studies in relevant animal models may help to elucidate them.

OBJECTIVE

To assess the effect of maternal anesthesia and surgery during pregnancy on the developing fetal brain, using a rabbit model.

MATERIALS AND METHODS

This is a randomized, sham-controlled study in time-mated pregnant does at 28 days of gestation (term = 31 days), which corresponds to the end of the second trimester in humans. Anesthesia was induced in 14 does (155 pups) with propofol and maintained with 4 vol% (equivalent to 1 minimum alveolar concentration) sevoflurane for 2 hours, and a laparotomy with minimal organ manipulation was performed (surgery group). Maternal vital signs (blood pressure, heart rate, peripheral and cerebral oxygen saturation, temperature, end-tidal CO₂, pH, lactate) were continuously monitored. Sham controls consisted of 7 does (74 pups) undergoing invasive hemodynamic monitoring for 2 hours without sedation. At term, does underwent cesarean delivery under ketamine-medetomidine sedation and local anesthesia. Pups either underwent motor and sensory neurologic testing followed by euthanasia at day 1 or daily neurodevelopment testing for 2 weeks and extensive neurologic assessment at 5 and 7 weeks (open field and object recognition test, T-maze, and radial-arm maze). Brains were harvested for histologic assessment of neuron density and synaptophysin expression.

RESULTS

Blood gases and vital parameters were stable in both groups. On postnatal day 1, surgery pups had significant lower motor (25 ± 1 vs 23 ± 3; P = .004) and sensory (16 ± 2 vs 15 ± 2; P = .005) neurobehavioral scores and lower brain-to-body weight ratios (3.7% ± 0.6% vs 3.4% ± 0.6%; P = .001). This was accompanied by lower neuron density in multiple brain regions (eg, hippocampus 2617 ± 410 vs 2053 ± 492 neurons/mm²; P = .004) with lower proliferation rates and less synaptophysin expression. Furthermore, surgery pups had delayed motor development during the first week of life, for example with hopping appearing later (6 ± 5 vs 12 ± 3 days; P = .011). Yet, by 7 weeks of age, neurobehavioral impairment was limited to a reduced digging behavior, and no differences in neuron density or synaptophysin expression were seen.

CONCLUSION

In rabbits, 2 hours of maternal general anesthesia and laparotomy, with minimal organ and no fetal manipulation, had a measurable impact on neonatal neurologic function and brain morphology. Pups had a slower motoric neurodevelopment, but by 7 weeks the effect became almost undetectable.

Nonobstetric Surgery During Pregnancy

One percent to 2% of pregnant women undergo nonobstetric surgery during pregnancy. Historically, there has been a reluctance to operate on pregnant women based on concerns for teratogenesis, pregnancy loss, or preterm birth. However, a careful review of published data suggests four major flaws affecting much of the available literature. Many studies contain outcomes data from past years in which diagnostic testing, surgical technique, and perioperative maternal-fetal care were so different from current experience as to make these data of limited utility today. This issue is further compounded by a tendency to combine experience from vastly disparate types of surgery into a single report. In addition, reports in nonobstetric journals often focus on maternal outcomes and contain insufficient detail regarding perinatal outcomes to allow distinction between complications associated with surgical disease and those attributable to surgery itself. Finally, most series are either uncontrolled or use the general population of pregnant women as controls rather than women with surgical disease who are managed nonsurgically. Consideration of these factors as well as our own extensive experience suggests that when the risks of maternal hypotension or hypoxia are minimal, or can be adequately mitigated, indicated surgery during any trimester does not appear to subject either the mother or fetus to risks significantly beyond those associated with the disease itself or the complications of surgery in nonpregnant individuals. In some cases, reluctance to operate during pregnancy becomes a self-fulfilling prophecy in which delay in surgery contributes to adverse perinatal outcomes traditionally attributed to surgery itself.

Pituitary Tumors in Pregnancy

Pituitary adenomas are common. The impact of pituitary tumors on fertility are mainly caused by oversecretion and/or undersecretion of pituitary hormones or compression of pituitary stalk and normal pituitary tissue by the tumor. Diagnosing and managing pituitary tumors during pregnancy involve many challenges, including the effect of hormone excess or deficiency on pregnancy outcome, changes in the pituitary or pituitary-related hormones, changes in tumor size, and the impact of various treatments of pituitary tumors on maternal and fetal outcomes. This article discusses the diagnosis and treatment of patients with prolactinomas, acromegaly, Cushing disease, and other pituitary tumors during pregnancy.

A Case Report of Paravertebral Block: A Safe Alternative for Microdiscectomy in a Pregnant Patient

Nonobstetric surgery during pregnancy is common. Administration of safe anesthesia to a pregnant patient, while minimizing its side effects on the fetus, is a major challenge for the anesthesiologist. Both general anesthesia and central neuraxial block are associated with risks during early pregnancy. Regional nerve blocks are being explored as possible alternatives whenever feasible. This report emphasizes the usefulness of ultrasound-guided, modified bilateral paravertebral block in a first-trimester pregnant patient undergoing microdiscectomy for cauda equina syndrome.

Cancer in Pregnancy

Cancer in pregnancy may be increasing in incidence with advancing maternal age and higher rates of obesity. The diagnosis of cancer in pregnancy provokes complex management issues balancing short- and long-term risks for both mother and baby. Every case needs to be individualized, with a multidisciplinary team of midwives, obstetricians, oncologists, surgeons, radiation oncologists, and neonatologists assisting the family to make informed decisions regarding the best treatment course for the mother and baby. The present article reviews the evidence regarding the safety of diagnostic imaging, procedures and treatment modalities for cancer for the pregnant woman and fetus. The efficacy of novel anticancer therapies highlight the need for International Registries to accumulate safety data for these agents in pregnancy as expeditiously as possible.

Metastatic uterine leiomyosarcoma at 26 weeks gestation

Uterine leiomyosarcoma (ULMS) is a highly malignant neoplasm which has been rarely described in pregnancy. A case of advanced metastatic ULMS presenting at 26 weeks gestation is reported. The principles in managing invasive cancer in pregnancy are discussed.

The adrenal cortex: Physiology and diseases in human pregnancy

Pregnancy is characterized by marked alterations in the hypothalamic-pituitary-adrenal axis and in the function of the adrenal gland. Some of those alterations have clinical characteristics that are similar to those of adrenal gland disorders. While adrenal disorders are rare among pregnant women, they harbor the potential for significant morbidity if they remain unrecognized and untreated. As the majority of patients with adrenal disorders present with clinical features that are typical of normal pregnancy - diagnosis during pregnancy is not uncommonly delayed. A high index of suspicion must be practiced for these disorders as they might carry severe obstetrical negative outcomes. In this review we will survey the normal function of adrenal glands in pregnancy and the role of adrenal hormones in pregnancy. We will outline the adrenal disorders that commonly present during pregnancy and review the literature on treatment modalities.

Management and outcome of colorectal cancer during pregnancy: report of 41 cases

BACKGROUND

Colorectal cancer in pregnancy is rare, with an incidence of 0.8 per 100,000 pregnancies. Advanced disease (stage III or IV) is diagnosed more frequently in pregnant patients. We aimed to review all cases of colorectal cancer in pregnancy from the International Network on Cancer, Infertility and Pregnancy database in order to learn more about this rare disease and improve its management.

METHODS

Data on the demographic features, symptoms, histopathology, diagnostic and therapeutic interventions and outcomes (obstetric, neonatal and maternal) were analysed.

RESULTS

Twenty-seven colon and 14 rectal cancer cases were identified. Advanced disease was present in 30 patients (73.2%). During pregnancy, 21 patients (51.2%) received surgery and 12 patients (29.3%) received chemotherapy. Thirty-three patients (80.5%) delivered live babies: 21 by caesarean section and 12 vaginally. Prematurity rate was high (78.8%). Eight babies were small for gestational age (27.6%). Three patients (10.7%) developed recurrence of disease. Overall 2-year survival was 64.4%.

CONCLUSION

Despite a more frequent presentation with advanced disease, colorectal cancer has a similar prognosis in pregnancy when compared with the general population. Diagnostic interventions and treatment should not be delayed due to the pregnancy but a balance between maternal and foetal wellbeing must always be kept in mind.

Octreotide use for rescue of vision in a pregnant patient with acromegaly

Pregnancy in acromegaly is rare and generally safe, but tumour expansion may occur. Managing tumour expansion during pregnancy is complex, due to the potential complications of surgery and side effects of anti-tumoural medication. A 32-year-old woman was diagnosed with acromegaly at 11-week gestation. She had a large macroadenoma invading the suprasellar cistern. She developed bitemporal hemianopia at 20-week gestation. She declined surgery and was commenced on 100 µg subcutaneous octreotide tds, with normalisation of her visual fields after 2 weeks of therapy. She had a further deterioration in her visual fields at 24-week gestation, which responded to an increase in subcutaneous octreotide to 150 µg tds. Her vision remained stable for the remainder of the pregnancy. She was diagnosed with gestational diabetes at 14/40 and was commenced on basal bolus insulin regimen at 22/40 gestation. She otherwise had no obstetric complications. Foetal growth continued along the 50th centile throughout pregnancy. She underwent an elective caesarean section at 34/40, foetal weight was 3.2 kg at birth with an APGAR score of 9. The neonate was examined by an experienced neonatologist and there were no congenital abnormalities identified. She opted not to breastfeed and she is menstruating regularly post-partum. She was commenced on octreotide LAR 40 mg and referred for surgery. At last follow-up, 2 years post-partum, the infant has been developing normally. In conclusion, our case describes a first presentation of acromegaly in pregnancy and rescue of visual field loss with somatostatin analogue therapy. Learning points: Tumour expansion may occur in acromegaly during pregnancy. Treatment options for tumour expansion in pregnancy include both medical and surgical options. Somatostatin analogues may be a viable medical alternative to surgery in patients with tumour expansion during pregnancy.

Intraoperative fetal heart monitoring for non-obstetric surgery: A systematic review

Limited data are available on fetal monitoring during non-obstetric surgery in pregnancy. We performed a systematic review to evaluate the incidence of emergent cesarean delivery performed for non-reassuring fetal heart rate patterns during non-obstetric surgery. Electronic databases were searched from their inception until October 2018 without limit for language. We included studies evaluating at least five cases of intraoperative fetal heart rate monitoring -either with ultrasound or cardiotocography- during non-obstetric surgery in pregnant women at ≥22 weeks of gestation. The primary outcome was the incidence of intraoperative cesarean delivery performed for non-reassuring fetal heart rate monitoring. Non-reassuring fetal heart rate monitoring was defined by attendant personnel, meeting NICHD criteria for category II or III patterns. Data extracted regarded type of study, demographic characteristics, maternal and perinatal outcomes. Statistical analysis was performed for continuous outcomes by calculating mean and standard deviations for appropriate variables. Of 120 studies identified, 4 with 41 cases of intraoperative monitoring met criteria for inclusion and were analyzed. Most (66%) surgeries were indicated for neurological or abdominal maternal issues and were performed under general anesthesia (88%) at a mean gestational age of 28 weeks. Minimal or absent fetal heart variability was noted in most cases and a 10-25 beats per minutes decrease in fetal heart rate baseline was observed in cases with general anesthesia. No intraoperative cesarean deliveries were needed. The incidence of non-reassuring fetal heart rate monitoring was 4.9% (2/41) and were limited to fetal tachycardia during maternal fever. Two (4.9%) cases of non-reassuring fetal heart rate monitoring were noted within the immediate 48 h after surgery, necessitating cesarean delivery. A single case of intrauterine fetal demise occurred four days postoperatively in a woman who had neurosurgery and remained comatose. In conclusion, limited data exist regarding the clinical application of fetal heart rate monitoring at viable gestational ages during non-obstetric surgical procedures. Fetal heart rate monitoring during non-obstetric surgery at ≥22 weeks was not associated with need for intraoperative cesarean delivery, but two (4.9%) cesarean deliveries were performed for non-reassuring fetal heart rate monitoring within 48 h after surgery.

An update on clinical care for pregnant women with acromegaly

INTRODUCTION

As pregnancy is rare in women with acromegaly, only case reports and few series have been published.

AREAS COVERED

All case reports and publications dealing with pregnancy in patients with acromegaly were collated. Information concerning the effects of acromegaly on pregnancy outcomes, the impact of pregnancy on GH/IGF-I measurements, acromegaly comorbidity and pituitary adenoma size, the effects of treatment of acromegaly on fetus outcomes were retrieved and analyzed.

EXPERT COMMENTARY

Based on the small number of reported cases, pregnancy is generally uneventful, except for a potential increased incidence of gestational hypertension and diabetes mellitus. Medical therapy of acromegaly (dopamine agonists, somatostatin analogs, growth hormone-receptor antagonists) is generally interrupted before or at diagnosis of pregnancy. In very rare patients with a pituitary adenoma, particularly a macroadenoma that has not been surgically treated before pregnancy, or if a surgical remnant persists, or when acromegaly is revealed during pregnancy, tumor volume may increase and cause symptoms through a mass effect. Close monitoring of clinical manifestations and imaging are necessary during pregnancy in these cases. In the rare cases of symptomatic tumor enlargement during pregnancy, medical treatment with dopamine agonists or eventually somatostatin analogs may be attempted before resorting to transsphenoidal surgery.

Cancer During Pregnancy: The Oncologist Overview

Although a rare and challenging condition, cancer during pregnancy should promptly be identified and treated. Not only standards of care guidelines for the underlying disease are taken into account, but also fetal safety might be weighted for clinical decisions. Frequent lack of experience and knowledge about this condition could lead to late diagnosis, imprecise management, suboptimal treatment and fetal and maternal harm. Therefore, this review aims to summarize the current evidence regarding the epidemiology, clinical presentation, diagnostic workup, staging and treatment, including novel treatment modalities for patients diagnosed with cancer during pregnancy.

Cancer in pregnancy

The incidence of cancer in pregnancy is increasing. The most frequent malignancies include breast and cervical cancers. Diagnosis may be complicated by late presentation. Imaging during pregnancy should consider risks to the fetus. Diagnostic work-up, including tumor markers, can be influenced by the physiology of pregnancy. Treatment of cancer can often be safely administered with good maternal and fetal outcomes. Chemotherapy, radiotherapy, and surgery must be adapted to the pregnancy state. Counselling and emotional support are an essential part of management.

Pregnancy outcomes following nonobstetric surgery during gestation: a nationwide population-based case-control study in Taiwan

Background

Whether nonobstetric surgery during gestation is associated with a higher risk of spontaneous abortion or adverse delivery outcomes is still unclear.

Methods

We performed a retrospective case-control study using a Longitudinal Health Insurance Database (LHID 2000) containing claim-data of 1 million randomly selected beneficiaries. We compared the incidences and estimated the adjusted odds ratios (aOR) with 95% confidence interval (95% CI) for spontaneous abortion, adverse delivery outcomes, cesarean delivery, and prolonged hospital stay to determine the risk of adverse outcomes in women who had nonobstetric surgery during gestation as compared to those who did not have any surgery during gestation.

Results

After exclusion, we were left with 114,852 delivery and 3999 abortion cases in our study; and 462 (0.39%) of them had nonobstetric surgery under general or regional anesthesia during pregnancy. The leading surgeries were repair of cervical os (33.12%), appendectomy (17.32%), ovarian surgeries (13.64%), and fixation of fractured bone (8.01%).The risk of spontaneous abortion (4.23% vs. 2.43%, aOR:1.53; 95% CI: 1.01–2.31), antepartum hemorrhage (7.14% vs. 2.83%, aOR: 2.51; 95% CI: 1.74–3.61), pre-eclampsia/eclampsia (2.60% vs. 1.01%, aOR: 2.35; 95% CI: 1.30–4.23), gestational diabetes (2.38% vs. 0.69%, aOR: 3.12; 95% CI: 1.69–5.78), prematurity (9.06 vs. 4.90%, aOR: 3.31; 95% CI: 2.54–4.31), cesarean section (43.55% vs. 33.76%, aOR: 1.41; 95% CI: 1.17–1.71), and prolonged hospital stay (1.82% vs. 5.91%, aOR: 3.23; 95% CI: 2.16–4.83) were higher in those women who had nonobstetric surgery after adjusting for age and comorbidities.

Conclusions

Nonobstetric surgery during gestation were associated with a higher risk of spontaneous abortion, adverse delivery outcomes, cesarean section, and prolonged hospital stay.

Systematic review of safety and efficacy of therapeutic endoscopic-retrograde-cholangiopancreatography during pregnancy including studies of radiation-free therapeutic endoscopic-retrograde-cholangiopancreatography

AIM

To systematically review safety/efficacy of therapeutic endoscopic-retrograde-cholangiopancreatography (ERCP) performed during pregnancy, considering fetal viability, fetal teratogenicity, premature delivery, and future postpartum development of the infant.

METHODS

Systematic computerized literature search performed using PubMed with the key words “ERCP” and “pregnancy”. Two clinicians independently reviewed the literature, and decided on which articles to incorporate in this review based on consensus and preassigned priorities. Large clinical trials, meta-analyses, systematic reviews, and controlled trials were assigned higher priority than review articles or small clinical series, and individual case reports were assigned lowest priority. Dr. Cappell has formal training and considerable experience in conducting systematic reviews, with 4 published systematic reviews in peer-reviewed journals indexed in PubMed during the last 2 years, and with a PhD in neurophysiology that involved 5 years of training and research in biomedical statistics.

RESULTS

Advances in imaging modalities, including abdominal ultrasound, MRCP, and endoscopic ultrasound, have generally obviated the need for diagnostic ERCP in non-pregnant and pregnant patients. Clinical experience with performing ERCP during pregnancy is burgeoning, with > 500 cases of therapeutic ERCP reported in the literature, aside from a national registry study of 58 patients. These studies show that therapeutic ERCP has a very high rate of technical success in clearing the bile duct of gallstones, and has a relatively low and acceptable rate of maternal and fetal complications. The great majority of births after therapeutic ERCP are full-term, have normal birth weights, and are healthy. A recent trend is performing ERCP without radiation to eliminate radiation teratogenicity. Systematic literature review reveals 147 cases of ERCP without fluoroscopy in 8 clinical series. These studies demonstrate extremely high technical success in endoscopically removing choledocholithiasis, favorable maternal outcomes with rare maternal ERCP complications, and excellent fetal outcomes. ERCP without fluoroscopy generally confirms proper biliary cannulation by aspiration of yellow bile per sphincterotome or leakage of yellow bile around an inserted guide-wire.

CONCLUSION

This systematic literature review reveals ERCP is relatively safe and efficacious during pregnancy, with relatively favorable maternal and fetal outcomes after ERCP. Recommendations are provided about ERCP indications, special ERCP techniques during pregnancy, and prospects for future research.

Management of gynecological cancer in pregnant patients

INTRODUCTION

Cancer during pregnancy is a rare but challenging condition. More women delay childbearing and consequently the incidence of cancer during pregnancy is constantly increasing.

EVIDENCE ACQUISITION

An extensive electronic search was performed in PubMed and Scopus. Only studies written after 1985 were considered eligible for this review. Abstracts, conference papers, book chapters, animal studies, commentaries as well as editorials articles were excluded from this review.

EVIDENCE SYNTHESIS

Cancer treatment during pregnancy is possible, but both maternal and fetal conditions need to be preserved. Randomized clinical trials are not feasible and current evidence are mainly based on case-series, small case reports and expert opinion. Cervical and ovarian cancers are the most common gynecological cancers diagnosed during pregnancy. Surgery and chemotherapy after the first trimester seem to be relatively safe for the newborn. Platinum-based chemotherapy administered during the 2nd-3rd trimester showed comparable adverse effects in newborns to those in the general population. Babies exposed to antenatal chemotherapy might be more likely to develop small for gestational age and NICU admission, than babies not exposed.

CONCLUSIONS

Management of pregnant women with cancer should be performed in specialized cancer centers and all cases should be discussed with a multidisciplinary approach. In the present review, we discuss the current recommendations for the management of pregnancies complicated by cancer and neonatal outcomes.

Anaesthesia for non-obstetric surgery in obstetric patients

Anaesthesia for pregnant patients presenting for non-obstetric surgery needs a thorough understanding of the physiological changes and altered pharmacokinetics of pregnancy. Considering the effects of surgery and anaesthesia on the foetus, only essential and emergency surgeries are performed during pregnancy. Surgical procedures in second trimester have the advantage of better foetal outcome. The primary concerns of maternal and foetal safety are achieved by a focused multidisciplinary team-based approach with respect to the surgical condition. Meticulous attention to preoperative patient counselling, airway management, haemodynamic stability, and thromboprophylaxis are the key factors in anaesthetic management. Choice of anaesthesia or anaesthetic drugs has minimal impact on the foetus provided utero-placental perfusion and uterine relaxation are maintained. Foetal monitoring when feasible and when done by a trained person enables to diagnose and treat the factors responsible for foetal heart rate variability. Anaesthetic technique needs to be modified according to the type of surgery.

Meningiomas in pregnancy: timing of surgery and clinical outcomes as observed in 104 cases and establishment of a best management strategy

BACKGROUND

There is a strong correlation between the level of circulating female sex hormones and the parturient growth of meningiomas. As a result, rapid changes in meningioma size occur during pregnancy, putting both the mother and fetus at risk. Large, symptomatic meningiomas require surgical resection, regardless of the status of pregnancy. However, the preferred timing of such complex intervention is a matter of debate. The rarity of this clinical scenario and the absence of prospective trials make it difficult to reach evidence-based conclusions. The aim of this study was to create evidence-based management guidelines for timing of surgery for pregnancy-related intracranial meningiomas.

METHOD

The English literature from 1990 to 2016 was systematically reviewed according to PRISMA guidelines for all surgical cases of pregnancy-related intracranial meningiomas. Cases were divided into two groups: patients who have had surgery during pregnancy and delivered thereafter (group A) and patients who delivered first (group B). Groups were compared for demographic, clinical and radiological features, as well as for neurosurgical, obstetrical and neonatological outcomes. Statistical analysis was performed to assess differences.

RESULTS

A total of 104 surgical cases were identified and reviewed, of which 86 were suitable for comparison and statistical analysis. Thirty-five patients (40%) underwent craniotomy for resection during pregnancy or at delivery (group A) and 51 patients (60%) underwent surgery after delivery (group B). Groups showed no significant differences in characteristics such as age at diagnosis, number of gestations, presenting symptoms, tumor site and tumor size. Despite a comparable distribution over the gestational trimesters, group A had significantly more patients diagnosed prior to the 27th gestational week (46 vs 17.5%, p = 0.0075). Group A was also associated with a significantly higher rate of both emergent craniotomies (40 vs 19.6%, p = 0.0048) and emergent Caesarian deliveries (47 vs 17.8%, p = 0.00481). The time from diagnosis to surgery was significantly longer in group B (11 weeks vs 1 week in group A, p = 0.0013). The rate of premature delivery was high but similar in both groups (∼70%). Risks of maternal mortality or fetal mortality were associated with group A (odds ratio = 14.7), but did not reach statistical significance.

CONCLUSIONS

While surgical resection of meningioma during pregnancy may be associated with increased maternal and fetal mortalities, the overall neurosurgical, obstetrical and neonatological outcomes, as well as many clinical characteristics, are similar to patients undergoing resection postpartum. We believe that fetal survival chances have a significant impact on decision-making, as patients diagnosed at a later stage in pregnancy (≥27th week of gestation) were more likely to undergo delivery first. This complicated clinical scenario requires the close cooperation of multiple disciplines. While the mother's health and well-being should always be paramount in guiding management, we hope that the overall good outcomes observed by this systematic review will encourage colleagues to aim for term pregnancies whenever possible in order to reduce prematurity-related problems.

Acute appendicitis complicating pregnancy: a 33 case series, diagnosis and management, features, maternal and neonatal outcomes

The occurrence of acute appendicitis during pregnancy may pose diagnostic and therapeutic difficulties. In fact pregnancy can make the clinical diagnosis delicate and the use of morphological examinations is still subject to controversy. The debates concerning the ideal surgical approach during pregnancy continue. On the other hand, in some cases the occurrence of acute appendicitis, especially in its complicated form, which is frequent in pregnant women, exposes to obstetrical complications and an increased risk of premature delivery We aims to describe the clinical and management features of acute appendicitis in pregnant women and the maternal and neonatal outcomes and carry out a review of the literature on this topic. It is a retrospective analysis of a series of 33 cases of appendicitis in pregnant women who were diagnosed and managed, in collaboration between the departments of General and digestive surgery, Gynecology and Obstetrics and Anaesthesia at Farhat Hached Universitary Hospital Sousse Tunisia between January 2005 and December 2015. The average age of the patients was 29 (20-40). Fourteen patients were in the first trimester, twelve in the 2^nd and seven in the third trimester. The main symptom was pain in the right iliac fossa. The mean delay between consultation and surgery was 2.7 days. Twenty five patients had a preoperative ultrasound. Eight of the 33 pregnant patients presented complicated appendicitis with localized or generalized peritonitis. Thirty patients underwent laparotomic appendectomy: 28 with a Mc Burney incision and 2 with a midline incision and only three patients underwent laparoscopy. Preventive tocolysis was given to 14 patients, maternal mortality was null. Twenty four pregnancies were followed until delivery: one case of premature birth and one case of preterm labor were observed. Pregnancy makes it difficult to diagnose appendicitis, which explains the high rate of complicated acute appendicitis in our series. An early treatment improves maternal and fetal outcome.
