Surgical impact of bilateral transient occlusion of uterine and utero-ovarian arteries during laparoscopic myomectomy.

The objective of this article is to compare the amount of intraoperative blood loss during laparoscopic myomectomy when performing bilateral transient clamping of the uterine and utero-ovarian arteries versus no intervention. It´s a randomized controlled prospective study carried out in the Department of Obstetrics and Gynecology Ramón y Cajal University Hospital and HM Montepríncipe-Sanchinarro University Hospital, Madrid, Spain, in women with fibroid uterus undergoing laparoscopic myomectomy. Eighty women diagnosed with symptomatic fibroid uterus were randomly assigned to undergo laparoscopic myomectomy without additional intervention (Group A) or temporary clamping of bilateral uterine and utero-ovarian arteries prior to laparoscopic myomectomy (Group B). Estimated blood loss, operating time, length of hospital stay, and postoperative hemoglobin values were compared in both groups. The number of fibroids removed was similar in both groups (p = 0.77). Estimated blood loss was lower in the group of patients with prior occlusion of uterine arteries (p = 0.025) without increasing operating time (p = 0.17) nor length of stay (p = 0.17). No patient had either intra or postoperative complications. Only two patients (2.5%) required blood transfusion after surgery. We conclude that temporary clamping of bilateral uterine arteries prior to laparoscopic myomectomy is a safe intervention that reduces blood loss without increasing operative time.

Application of Ultrasound Scores (Subjective Assessment, Simple Rules Risk Assessment, ADNEX Model, O-RADS) to Adnexal Masses of Difficult Classification.

BACKGROUND: Ultrasound features help to differentiate benign from malignant masses, and some of them are included in the ultrasound (US) scores. The main aim of this work is to describe the ultrasound features of certain adnexal masses of difficult classification and to analyse them according to the most frequently used US scores. METHODS: Retrospective studies of adnexal lesions are difficult to classify by US scores in women undergoing surgery. Ultrasound characteristics were analysed, and masses were classified according to the Subjective Assessment of the ultrasonographer (SA) and other US scores (IOTA Simple Rules Risk Assessment-SRRA, ADNEX model with and without CA125 and O-RADS). RESULTS: A total of 133 adnexal masses were studied (benign: 66.2%, n:88; malignant: 33.8%, n:45) in a sample of women with mean age 56.5 ± 7.8 years. Malignant lesions were identified by SA in all cases. Borderline ovarian tumors (n:13) were not always detected by some US scores (SRRA: 76.9%, ADNEX model without and with CA125: 76.9% and 84.6%) nor were serous carcinoma (n:19) (SRRA: 89.5%), clear cell carcinoma (n:9) (SRRA: 66.7%) or endometrioid carcinoma (n:4) (ADNEX model without CA125: 75.0%). While most teratomas and serous cystadenomas have been correctly differentiated, other benign lesions were misclassified because of the presence of solid areas or papillae. Fibromas (n:13) were better identified by SA (23.1% malignancy), but worse with the other US scores (SRRA: 69.2%, ADNEX model without and with CA125: 84.6% and 69.2%, O-RADS: 53.8%). Cystoadenofibromas (n:10) were difficult to distinguish from malignant masses via all scores except SRRA (SA: 70.0%, SRRA: 20.0%, ADNEX model without and with CA125: 60.0% and 50.0%, O-RADS: 90.0%). Mucinous cystadenomas (n:12) were misdiagnosed as malignant in more than 15% of the cases in all US scores (SA: 33.3%, SRRA: 16.7%, ADNEX model without and with CA125: 16.7% and 16.7%, O-RADS:41.7%). Brenner tumors are also difficult to classify using all scores. CONCLUSION: Some malignant masses (borderline ovarian tumors, serous carcinoma, clear cell carcinoma, endometrioid carcinomas) are not always detected by US scores. Fibromas, cystoadenofibromas, some mucinous cystadenomas and Brenner tumors may present solid components/papillae that may induce confusion with malignant lesions. Most teratomas and serous cystadenomas are usually correctly classified.

Ultrasound Features and Ultrasound Scores in the Differentiation between Benign and Malignant Adnexal Masses.

BACKGROUND: Several ultrasound (US) features help ultrasound experts in the classification of benign vs. malignant adnexal masses. US scores serve in this differentiation, but they all have misdiagnoses. The main objective of this study is to evaluate what ultrasound characteristics are associated with malignancy influencing ultrasound scores. METHODS: This is a retrospective analysis of ultrasound features of adnexal lesions of women managed surgically. Ultrasound characteristics were analyzed, and masses were classified by subjective assessment of the ultrasonographer (SA) and other ultrasound scores (IOTA Simple Rules Risk Assessment SRRA, ADNEX model, and O-RADS). RESULTS: Of a total of 187 adnexal masses studied, 134 were benign (71.7%) and 53 were malignant (28.3%). SA, IOTA SRRA, ADNEX model with or without CA125 and O-RADS had high levels of sensitivity (93.9%, 81.1%, 94.3%, 88.7%, 98.1%) but lower specificity (80.2%, 82.1%, 82.8%, 77.6%, 73.1%) with similar AUC (0.87, 0.87, 0.92, 0.90, 0.86). Ultrasound features significantly related with malignancy were the presence of irregular contour, absence of acoustic shadowing, vascularized solid areas, ≥1 papillae, vascularized septum, and moderate-severe ascites. CONCLUSION: IOTA SRRA, ADNEX model, and O-RADS can help in the classification of benign and malignant masses. Certain ultrasound characteristics studied in ultrasound scores are associated with malignancy.

Comparison of Ultrasound Scores in Differentiating between Benign and Malignant Adnexal Masses.

Subjective ultrasound assessment by an expert examiner is meant to be the best option for the differentiation between benign and malignant adnexal masses. Different ultrasound scores can help in the classification, but whether one of them is significantly better than others is still a matter of debate. The main aim of this work is to compare the diagnostic performance of some of these scores in the evaluation of adnexal masses in the same set of patients. This is a retrospective study of a consecutive series of women diagnosed as having a persistent adnexal mass and managed surgically. Ultrasound characteristics were analyzed according to IOTA criteria. Masses were classified according to the subjective impression of the sonographer and other ultrasound scores (IOTA simple rules -SR-, IOTA simple rules risk assessment -SRRA-, O-RADS classification, and ADNEX model -with and without CA125 value-). A total of 122 women were included. Sixty-two women were postmenopausal (50.8%). Eighty-one women had a benign mass (66.4%), and 41 (33.6%) had a malignant tumor. The sensitivity of subjective assessment, IOTA SR, IOTA SRRA, and ADNEX model with or without CA125 and O-RADS was 87.8%, 66.7%, 78.1%, 95.1%, 87.8%, and 90.2%, respectively. The specificity for these approaches was 69.1%, 89.2%, 72.8%, 74.1%, 67.9%, and 60.5%, respectively. All methods with similar AUC (0.81, 0.78, 0.80, 0.88, 0.84, and 0.75, respectively). We concluded that IOTA SR, IOTA SRRA, and ADNEX models with or without CA125 and O-RADS can help in the differentiation of benign and malignant masses, and their performance is similar to the subjective assessment of an experienced sonographer.

Nongalenic pial arteriovenous fistula: Prenatal diagnosis.

Pial arteriovenous (AV) fistulae have rarely been diagnosed in utero. They are characterized by one or more pial arteries flowing directly into a cortical vein without any shunt or interposed capillary bed. In the fetus and the newborn up to 2 years of age, the most common clinical manifestation is heart failure resulting from fistula overload. Later on, hydrocephalus, focal neurologic deficits, headaches, seizures, and cerebral hemorrhage are the most common manifestations. We present a case of nongalenic pial AV fistula diagnosed in the 25th week of pregnancy, which resulted in intrauterine fetal death due to congestive heart failure. © 2017 Wiley Periodicals, Inc.

Are congenital malformations more frequent in fetuses with intrahepatic persistent right umbilical vein? A comparative study.

OBJECTIVE: Persistent right umbilical vein (PRUV) is a vascular anomaly where the right umbilical vein remains as the only conduit that returns oxygenated blood to the fetus. It has classically been described as associated with numerous defects. We distinguish the intrahepatic variant (better prognosis) and the extrahepatic variant (associated with worse prognosis). The objective of this study was to compare rates of congenital malformations in fetuses with intrahepatic PRUV (I-PRUV) versus singleton pregnancies without risk factors. MATERIALS AND METHODS: A multicenter, crossover design, comparative study was performed between 2003 and 2013 on fetuses diagnosed with I-PRUV (n=56), and singleton pregnancies without congenital malformation risk factors (n=4050). RESULTS: Fifty-six cases of I-PRUV were diagnosed (incidence 1:770). A statistically significant association between I-PRUV and the presence of congenital malformations (odds ratio 4.321; 95% confidence interval 2.15-8.69) was found. This positive association was only observed with genitourinary malformations (odds ratio 3.038; 95% confidence interval 1.08-8.56). CONCLUSION: Our rate of malformations associated with I-PRUV (17.9%) is similar to previously published rates. I-PRUV has shown a significant increase in the rate of associated malformations, although this association has only been found to be statistically significant in the genitourinary system. Noteworthy is the fact that this comparative study has not pointed to a significant increase in the congenital heart malformation rate. Diagnosis of isolated I-PRUV does not carry a worse prognosis.

Manejo conservador de incarceración uterina en 2 gestantes de segundo trimestre / Conservative management of uterine incarceration in the second trimester. Two case report

Presentamos 2 casos de gestantes en el segundo trimestre de embarazo que acudieron a nuestro centro por dolor e incapacidad para orinar, siendo diagnosticadas gracias a la exploración clínica y a la ecografía de incarceración uterina. Ambas fueron manejadas de forma conservadora, una mediante reducción manual con sedación y la otra mediante sondaje vesical y analgesia, lo que facilitó la resolución espontánea del caso. La incarceración uterina es una patología que tiene lugar con mayor frecuencia en el segundo trimestre de la gestación. Ocurre en mujeres gestantes, en la mayoría de las ocasiones, con un útero en retroversión. El aumento del tamaño del útero debido a la gestación produce un atrapamiento uterino entre el promontorio del sacro y la sínfisis del pubis. La clínica habitual es dolor e incapacidad para orinar. El diagnóstico debe estar basado en la exploración clínica y en la ecografía. El tratamiento habitual se basa en la reducción manual en quirófano que suele tener éxito en la mayoría de las ocasiones (AU)

We report the cases of 2 women in the second trimester of pregnancy who attended our center with pain and difficulty voiding. Based on physical and ultrasound examination, both women were diagnosed with uterine incarceration. Management was conservative in both patients, through manual reduction under sedation in one and by bladder catheterization and analgesia in the other, facilitating spontaneous resolution of the uterine incarceration. Uterine incarceration is a rare entity that occurs most frequently in the second trimester. It affects pregnant women, usually with retroverted uterus. The enlarged uterus due to pregnancy induces uterine entrapment in the pelvis between the sacral promontory and pubic symphysis. The most common symptoms are pain and progressive difficulty in voiding. The diagnosis of incarcerated uterus is based on physical and ultrasound examination. The usual treatment is based on manual reduction, which is usually successful (AU)

[Prenatal diagnosis of right aortic arch. Types of presentation and postnatal evolution]. / Diagnóstico prenatal de arco aórtico derecho. Formas de presentación y evolución posnatal.

BACKGROUND: Right aortic arch is the most common abnormality of the aortic arch, excluding aberrant right subclavian artery. Its importance lies in its association with genetic syndromes, another important congenital heart defects, and that may cause clinical symptons from vascular rings. OBJECTIVE: Was to describe the prenatal clinical presentation, the correlation with postnatal findings and postnatal development of the fetus. METHODS: Observational retrospective analysis of 18 cases of right aortic arch diagnosed prenatally between the years 2005-2011. RESULTS: 5 pregnancies were interrupted because of ultrasound findings associated with poor prognosis. In 13 cases were term infants, with a good correlation between prenatal and postnatal findings, and the prognosis was excellent in cases in which the prenatal diagnosis of right aortic arch was isolated. CONCLUSIONS: In our experience, right aortic arch is a rare condition, but it can be associated with important congenital heart defects (heart disease or vascular rings) and/or other morphological anomalies in the fetus, in which case it should be ruled out chromosomal or genetic syndrome. If prenatally is considered an isolated finding, after careful ultrasound assessment by obstetricians and pediatric cardiologists, it is likely that evolution will be favorable postnatally.

Hysteroscopy in pregnancy-related conditions: descriptive analysis in 273 patients.

STUDY OBJECTIVE: To describe the feasibility of office hysteroscopy in patients with pregnancy-related problems such as retained trophoblastic tissue, persistent molar tissue, pregnancy with in situ intrauterine device (IUD), isthmocele, embryoscopy, and osseous metaplasia. DESIGN: Retrospective cohort chart review of use of hysteroscopy in 273 patients with pregnancy-related conditions (Canadian Task Force classification II-2). SETTING: University tertiary-care hospital. PATIENTS: Office hysteroscopy with the indication of pregnancy-related conditions such as retained trophoblastic tissue, pregnancy with IUD, molar pregnancy, cesarean scar defects, and fetal death were studied. The study included 273 patients: 185 with retained trophoblastic tissue, 14 with persistent molar tissue, 7 with an in situ IUD, 22 with symptomatic isthmocele, 41 with embryoscopy, and 4 with osseous metaplasia. INTERVENTION: Diagnostic and operative office hysteroscopy. MEASUREMENTS AND MAIN RESULTS: Variables studied included resolution of abnormal uterine bleeding in patients with persistent trophoblastic tissue, normalization of ß-human chorionic gonadotropin levels in patients with persistent molar tissue, continuation of pregnancy after retrieval of lost IUDs, resolution of postmenstrual bleeding in patients with symptomatic isthmocele, rate of uncontaminated embryonic tissue after embryoscopic biopsy, and successful extraction of bony tissue in patients with osseous metaplasia. Office hysteroscopy enabled resolution of most cases of retained trophoblastic tissue (91.8%) and all 14 cases of persistent molar tissue. 7 IUDs were extracted from pregnant patients. Fifteen isthmoceles resolved with office hysteroscopy, and 7 were resected in the operating room. A normal karyotype was obtained in 37 embryoscopies (90.2%). Four osseous metaplasia cases resolved with either office hysteroscopy (75%) or resectoscopy in the operating room (25%). CONCLUSION: Office hysteroscopy is a safe and minimally invasive treatment for pregnancy-related conditions, with good clinical and functional results.

Evisceración transvaginal espontánea en paciente anciana con prolapso genital / Spontaneous vaginal evisceration in an elderly woman with genital prolapse

Presentamos el caso de una paciente con evisceración vaginal sin antecedentes de cirugía vaginal. La paciente fue intervenida en nuestro centro, realizándose una laparotomía con reposición de asas intestinales, corrección del defecto e histerectomía vaginal. En mujeres posmenopáusicas, la evisceración transvaginal se asocia a un aumento de la presión abdominal, la ulceración vaginal y los esfuerzos al defecar. En un 73% de los casos, existe algún tipo de cirugía vaginal previa. La clínica habitual es dolor, sangrado o sensación de masa en el introito. El íleo terminal es la víscera más frecuentemente implicada y el fórnix posterior de la vagina, el lugar más frecuente de herniación. La prevención está orientada a evitar intervenciones repetidas, alteraciones del suelo pélvico, hipoestrogenismo y aumento de la presión intraabdominal (AU)

We report the case of a patient with vaginal evisceration and no history of vaginal surgery. We performed a laparotomy with bowel replacement, correction of the defect and vaginal hysterectomy. In postmenopausal women, transvaginal evisceration is associated with increased abdominal pressure, vaginal ulceration and straining at stool. In 73% of patients, there is some type of prior vaginal surgery. The most common symptoms are pain, bleeding or sensation of a mass at the introitus. The most commonly involved viscera is the terminal ileum and the most common site of herniation is the posterior fornix of the vagina. Prevention is aimed at avoiding repeat interventions, pelvic floor disorders, hypoestrogenism, and increased abdominal pressure (AU)
