Reviving forgotten techniques: Vaginal salpingectomy in public health system, a retrospective cohort study.

OBJECTIVE: To evaluate the viability of the vaginal route as an alternative to laparoscopy for patients seeking permanent surgical contraception. METHODS: We conducted a retrospective cohort study in 2021, dividing patients into two groups based on their preference: vaginal and laparoscopic salpingectomy. The statistical analysis was conducted using STATA, employing standard statistical methods based on the distribution of variables. RESULTS: The study included 64 patients, with 34 undergoing the vaginal approach and 30 the laparoscopic route. No statistically significant differences were observed in baseline characteristics or complications between the two groups. Both surgical methods were found to be feasible. The vaginal route demonstrated a significantly shorter mean surgical time (P < 0.001). The laparoscopic route exhibited significantly less intraoperative blood loss (P < 0.001) and fewer hospitalization hours (P = 0.008). Postoperative satisfaction and pain levels did not show statistically significant differences. CONCLUSION: Vaginal salpingectomy is a feasible technique with low complication rates, making it a potential option for gynecologists to offer their patients. We propose vaginal route inclusion in the training curriculum for gynecologic surgeons during the residency program, without any subspecialty requirements.

[Interstitial ectopic pregnancy: report of an unusual location]. / Embarazo ectópico cornual: reporte de una localización inusual.

Ectopic pregnancy occurs when a developing blastocyst implants at any site other than the uterine cavity. Ectopic pregnancy is most commonly found in the fallopian tube but may also occur in the cornua of the uterus (also found as interstitial in the literature), cervix, ovary, or abdominal cavity or in a cesarean scar. An estimated 2% of pregnancies are ectopic, of which an interstitial pregnancy represents an extremely rare variant of ectopic pregnancy (EP), accounting for 2% to 4 % of all cases. The aim of this report is to describe the case of a patient with suspected ectopic pregnancy of uncertain location in which an exploratory laparoscopy was performed due to the onset of symptoms, discovering a cornual ectopic pregnancy in site of a past salpingectomy because of a tubal ectopic pregnancy. A cornuotomy by laparoscopy was performed to resect the cornual ectopic pregnancy. The patient had an uneventful postoperative course, with negativization of human chorionic gonadotropin levels. This type of location is rare and is associated with high rates of maternal morbidity and mortality. It represents a diagnostic and therapeutic challenge for the gynecologist who faces it.

Se define a un embarazo ectópico cuando el blastocisto en desarrollo se implanta fuera de la cavidad uterina. La localización más frecuente es en la trompa, pero también puede ocurrir en el ovario, cérvix, cicatriz de cesárea, cuerno uterino (también mencionado como intersticial en la literatura) o abdominal. Se estima que la incidencia de embarazo ectópico es aproximadamente el 2% de todos los embarazos, siendo la localización cornual solo el 2-4% de esos casos. El objetivo de este reporte es describir el caso de una paciente con sospecha de embarazo ectópico de localización incierta a quien se le realizó una laparoscopia exploradora por inicio de síntomas, evidenciando un embarazo ectópico cornual en el lecho de una salpingectomía, producto de un embarazo ectópico tubario previo. Se realizó la cornuotomía con resección del mismo por laparoscopia y su evolución fue favorable con negativización de la subunidad beta. Este tipo de localización es rara y se asocia con grandes tasas de morbimortalidad materna. Representa un desafío diagnóstico y terapéutico para el ginecólogo que lo enfrenta.

Anesthetic effects of isoflurane and fentanyl infusion in capuchin monkeys (Sapajus sp) undergoing salpingectomy or deferentectomy, previously chemically restrained with ketamine-midazolam or ketamine-dexmedetomidine.

BACKGROUND: This study evaluated the anesthetic and cardiorespiratory effects of two anesthetic protocols for salpingectomy or deferentectomy in capuchin monkeys (Sapajus sp). MATERIALS AND METHODS: Five capuchin monkeys (5 per group) received ketamine (20 mg/kg) combined with midazolam (0.5 mg/kg; group KM) or dexmedetomidine (5 µg/kg; group KD) intramuscularly. Anesthesia is induced with propofol intravenously and maintained with isoflurane. Before the start of surgery, fentanyl 3 µg/kg was administered IV, and continuous infusion (10 µg/kg/min) IV was started. Times and quality of anesthetic recovery were evaluated postoperatively. RESULTS: KM and KD resulted in adequate chemical restraint. KD resulted in bradycardia. Intraoperative heart rate and systolic blood pressure were higher in KM than in KD. Both groups had smooth recovery. Time to standing was longer in KM than in KD. CONCLUSION: Both protocols allowed the performance of surgeries, with few cardiorespiratory effects. Anesthetic recovery was smooth and shorter in KD group.

A case report of a successful multidisciplinary management of an abdominal pregnancy / Manejo multidisciplinario exitoso del embarazo abdominal. Reporte de un caso peruano

Abdominal pregnancy is defined as one that occurs outside of the uterus and fallopian tubes in the abdominal cavity. We present the case of a 30-year-old Peruvian female patient from Lima with a surgical history of exploratory laparotomy due to tubal ectopic pregnancy and appendectomy without further relevant personal or family histories. She attended the emergency room of a social security hospital in Peru with a referral from a district hospital and a diagnosis of abdominal pregnancy at 14 weeks of gestational age without previous prenatal controls. Symptomatology at hospital admission was colic-type abdominal pain in the hypogastrium without vaginal bleeding, fluid loss or fever. During hospitalization, she underwent an exploratory laparotomy with embolization of the uterine artery, left salpingectomy, and removal of the abdominal ectopic pregnancy. The evolution was favorable after the surgery, and she was discharged. Without further complications, she continues her controls at the obstetrics and gynecology outpatient service without complications.

Atualmente muitos répteis se tornaram animais de companhia e são mantidos como pet's exóticos. A espécie Trachemys scripta elegans, Wied (1839) é um animal exótico da América do Norte, sua identificação é realizada pelas marcas avermelhadas encontradas lateralmente a sua cabeça. Na rotina clínica as principais enfermidades que acometem os quelônios são as de origem reprodutiva, como a estase folicular e distocia. O objetivo deste trabalho foi relatar um caso recorrente de distocia em um tigre d'água fêmea, para isso, a anamnese, o histórico da paciente, e seus sinais clínicos, em conjunto com os exames complementares de imagem foram essenciais para se obter diagnóstico definitivo. O tratamento foi realizado com a indução medicamentosa utilizando borogluconato de cálcio, seguida da aplicação de ocitocina, esta trouxe resultados positivos para a eliminação dos ovos. Porém devido ao histórico do paciente, optou-se pela intervenção cirúrgica de ovariossalpingectomia, sendo está a maneira permanente de resolução da patologia. O protocolo terapêutico escolhido proporcionou um resultado satisfatório e bem estar ao animal.(AU)

Currently, many reptiles have become companion animals and are kept as exotic pets. The species Trachemys scripta elegans, Wied (1839) is an exotic animal from North America, and its identification is based on the reddish markings found laterally on its head. In routine clinical practice, the main diseases that affect chelonians are those of reproductive origin, such as follicular stasis and dystocia. The aim of this study was to report a recurrent case of dystocia in a female red-eared slider turtle. For this purpose, the patient's anamnesis, history, and clinical signs, along with complementary imaging exams, were essential to obtain a definitive diagnosis. The treatment involved medical induction using calcium borogluconate, followed by the administration of oxytocin, which yielded positive results in egg elimination. However, due to the patient's history, surgical intervention in the form of ovariosalpingectomy was chosen as the permanent solution to the pathology. The chosen therapeutic protocol provided a satisfactory outcome and improved the animal's well-being.(AU)

Applicability, Safety, and Efficiency of Salpingectomy versus Electrocoagulation and Laparoscopic Tubal Section in Ambulatory / Aplicabilidade, segurança e eficiência da salpingectomia versus eletrocoagulação e secção tubar laparoscópica em regime de ambulatório

Abstract Objective Female sterilization is a surgical procedure that aims women to permanently stop the use of conception. The benefits, risks and cost-effectiveness are important issues. The purpose of this study was comparing the applicability, complications and efficacy of salpingectomy versus electrocoagulation and tubal occlusion by laparoscopy in the Ambulatory Surgery Unit. Methods We performed a retrospective and observational study that included women undergoing laparoscopic sterilization procedures at our Ambulatory Surgery Unit, during three years. Statistical analysis was performed using SPSS, applying the Fisher exact test, the Mann-Whitney test, and Linear Regression. Results Two hundred and twenty-one laparoscopic surgical procedures were performed, including 79 (35.7%) bilateral total salpingectomies and 142 (64.3%) electrocoagulation and bilateral tubal occlusion procedures. The majority of the procedures were performed by a resident (n = 162; 73.3%), with 40% (n = 33) of salpingectomies. The surgical time, independently the type of surgeon, was significantly shorter in the tubal occlusion (42.2 vs. 52.7 min, p < 0.001). Safety and efficacy endpoints were not significantly different between the two groups, with a case of pregnancy in tubal occlusion group. Conclusion Salpingectomy is a safe and effective alternative comparing with electrocoagulation and tubal occlusion.

A 27-Year-Old Brazilian Woman with a History of Left Salpingectomy and Late Diagnosis of an Extra-Uterine Intra-Abdominal Pregnancy and Live Birth at 26 Weeks' Gestation.

BACKGROUND Abdominal pregnancy is a special type of ectopic pregnancy, characterized by implantation of the embryo in the peritoneal cavity, with tubal, ovarian, and intraligamentary pregnancies excluded, accounting for approximately 1% of all cases. It was first reported in 1708 after an autopsy and since then numerous cases have been reported, with a current incidence of 1: 10 000 to 1: 30 000 pregnancies. CASE REPORT We report the case of a 27-year-old woman, resident of the city of Caxias do Sul, Brazil, with an extra-uterine pregnancy by ultrasound diagnosis at 25 weeks and 1 day of gestational age and a live fetus. CONCLUSIONS Abdominal gestation is a rare type of ectopic pregnancy and is characterized as a life-threatening situation. Its biggest challenge is to make an early diagnosis, since most cases go unnoticed at the ultrasound performed in the first trimester, and when symptomatic, they do not present themselves in a specific way. When necessary, MRI has been shown to greatly elucidate such cases. Moreover, the therapeutic decision also presents some disparities in the literature. Although it is known that open surgery is best option, there are still many doubts regarding whether to perform placental extraction since its removal process can cause abundant bleeding, putting the patient at risk during the surgical procedure, in the same way that its maintenance and the use of drug treatment can also aggravate the patient's clinical picture.

Hiperplasia endometrial cística em uma coelha-doméstica (Oryctolagus cuniculus domesticus) / Cystic endometrial hyperplasia in a domestic rabbit (Oryctolagus cuniculus domesticus)

Background: Cystic endometrial hyperplasia is a hormone-dependent disease induced by systemic increase in progesteronethat can occur in several domestic species, such as the rabbit. This disease may be associated with sex steroid hormones,especially progesterone, and may be asymptomatic, and it is diagnosed using complementary imaging tests such as totalabdominal ultrasound. However, surgical excisional biopsy with histopathological tissue analysis is the gold standard. Thisstudy reports a case of asymptomatic cystic endometrial hyperplasia in a female Miniature Lion Lop rabbit (Oryctolaguscuniculus domesticus) treated with therapeutic ovariohysterectomy.Case: A domestic, adult, female Miniature Lion Lop rabbit (Oryctolagus cuniculus domesticus), aged approximately 5 yearsand weighing 3.2 kg, was referred to specialized care to undergo ovariohysterectomy, an elective procedure. The tutor onlyreported the occurrence of a single episode of vulvar secretion more than 2 years ago, treated with antibiotics, with remissionof clinical signs. In the intraoperative period after celiotomy, the uterine horn and uterine body showed a significant increasein volume, with abnormal color changes and tissue consistency; however, both changes were clinically asymptomatic. Subsequently, biopsy was performed during the ovariohysterectomy procedure. The excised uterus and ovaries were placed in 10%formalin and histopathologically analyzed. The macroscopic histopathological examination of the sectioned tissue revealed aslight amount of brownish fluid inside the uterine horns, in addition to multiple cystic areas in the uterine mucosa. Microscopicexamination revealed marked hyperplasia of well-differentiated endometrial epithelial cells, occasionally forming cystic structuresof different sizes. Moderate congestion, mild multifocal hemorrhage, and mild multifocal inflammatory infiltrate in the lamina...

Effects of hydrosalpinx on endometrial implantation failures: evaluating salpingectomy in women undergoing in vitro fertilization / Efeitos do hydrosalpinx no falho de implantação endometrial: Avaliar a salpingectomia nas mulheres em curso de fertilização in vitro

Abstract Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Evidence suggests that the presence of hydrosalpinx reduces the rate of pregnancy with assisted reproductive technology. The main aim of the present is review to make an overview of the possible effects of hydrosalpinx on in vitro fertilization (IVF).We conducted a literature search on the PubMed, Ovid MEDLINE, and Google Scholar data bases regarding hydrosalpinx and IVF outcomes. Hydrosalpinx probably has a direct toxic effect on sperm motility and on the embryos. In addition, the increasing liquid inside the salpinges could alter the mechanisms of endometrial receptivity. The window of endometrial receptivity is essential in the implantation of blastocysts, and it triggers multiple reactions arising from the endometrium as well as the blastocysts. Hydrosalpinx could influence the expression of homeobox A10 (HOXA10) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10; therefore, it may be one mechanism by which tubal

Effects of Hydrosalpinx on Endometrial Implantation Failures: Evaluating Salpingectomy in Women Undergoing in vitro fertilization.

Hydrosalpinx could influence the expression of homeobox A10 (HOXA10) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10; therefore, it may be one mechanism by which tubal removal could result in improved implantation rates in IVF. In addition, salpingectomy does not affect the ovarian response, nor reduces the antral follicle count. Further studies are needed to establish the therapeutic value of fluid aspiration under ultrasonographic guidance, during or after oocyte retrieval, in terms of pregnancy rate and ongoing pregnancy.

Expression of matrix metalloproteinases and their inhibitors at the implantation site in ampullary ectopic pregnancies.

OBJECTIVE: This study investigated the qualitative and semi-quantitative expression of metalloproteinases (MMP) and their tissue inhibitors (TIMP) in trophoblastic tissue during ampullary ectopic pregnancies and correlated that expression with the degree of tubal invasion. STUDY DESIGN: It is a prospective study that included 34 patients diagnosed with ampullary tubal pregnancy who underwent salpingectomy. A histological evaluation of the depth of trophoblastic invasion in the tubes obtained was performed. Subsequently, the expression of the MMP-2, MMP-9, MMP-14, TIMP-1, TIMP-2 and TIMP-3 markers was qualitatively and semi-quantitatively evaluated by indirect immunohistochemistry. In addition, the degree of trophoblastic invasion was correlated with the expression of each marker and with the metalloproteinase/inhibitor ratios. RESULTS: MMP-2 (11.2 %; 3.6-17.9) was the marker with greater expression at the implantation site, both in the qualitative and semi-quantitative assessment, while MMP-9 (2.23 %; 0.2-5.4) and TIMP-3 (2.53 %; 0.1-15.3) were only weakly expressed. CONCLUSION: There was wide variation in expression among the markers and metalloproteinase/inhibitor ratios studied compared to the degrees of invasion.

Hydronephrosis in a dog related to ovariosalpingohysterectomy

Background: Hydronephrosis is the dilation of the pelvis and renal calyxes due to post-renal obstruction. The obstruction is often associated with extraluminal masses, blood clots and ureter ligation in castration procedures. Ureter ligation is reported as a malpractice. The renal function is reestablished if ligation is rapidly undone, but not for obstructions longer than four weeks. Often, clinical signs are results from months to years after the castration, when nephrectomy is the best therapeutic option. This paper aims to report a case of asymptomatic unilateral hydronephrosis in a 10-year-old dog caused by chronic ureter occlusion with Nylon 3.0 suture during an elective procedure. Case: A 10-year-old female pinscher dog, spayed 3 years ago was admitted at the Surgery Department of the Veterinary Hospital of the Federal University of Jataí (HV-UFJ). The animal was taken for periodontal treatment. In the physical and laboratory examination (complete blood count, hepatic and renal biochemical tests) no significant and noteworthy alterations were found. Ultrasonographic examination showed no changes in the topography and echotexture of the left kidney, however the right kidney was not visualized, with an anechoic structure suggestive of advanced and severe hydronephrosis. Therefore, exploratory laparotomy was proposed to identify the observed structure, with the periodontal treatment considered for a later time. So, a retroumbilical incision was made, followed by linea alba and the removal of simple isolated suture remaining from previous surgical procedure. In the cavity, the viscera were isolated and the left kidney was identified, observing preserved anatomy. On the other hand, the right kidney had altered topography and morphology, being exposed after release of adhesions in adjacent structures. The right renal artery and vein were dissected and a double ligature was made. Then, the right ureter was dissected, observing marked dilatation in the proximal portion and the presence of local ligation with Nylon 3.0. Right ureterectomy and right nephrectomy were performed. After nephrectomy, the capsule was ruptured, observing dark fluid in it and absence of tissue compatible with renal parenchyma. The material was preserved in 10% formaldehyde and sent for histopathological examination. Histopathology revealed risk of rupture of the renal capsule due to the advance of renal degeneration and complete absence of parenchyma. However, contrary to the severity of the histopathological, surgical and ultrasonographic findings, the patient did not present clinical signs at the time of diagnosis. Discussion: In the intraoperative evaluation, the cause of the hydronephrosis was verified to be in fact the ligation of the ureter, which may have been accidental or due to the malpractice of the veterinarian surgeon. Other possible causes such as adhesions and granulomas were ruled out because the Nylon 3.0 suture was found in the proximal portion of the right ureter. It is believed that the patient may have presented clinical signs of hydronephrosis that may have been confused by the tutors as postoperative complications, changes that if identified and performed in time, could have avoided the occurrence or worsening of hydronephrosis and subsequent nephrectomy. Clinically, the bitch did not show clinical signs presented in the literature as consistent with hydronephrosis such as polyuria, polydipsia, abdominalgia, external fistula and anorexia. Therefore, it is believed that this case is one of the first reports of the occurrence of severe hydronephrosis without typical clinical manifestations of hydronephrosis. This fact raises a warning about the thorough monitoring in the postoperative period by owners and veterinarians, in addition to highlighting concerns regarding the occurrence of medical malpractice versus surgical accidents.

Celioscopy and partial salpingectomy in a pregnant bitch / Celioscopia e salpingectomia parcial em fêmea canina gestante

This case report presents a celioscopy procedure followed by partial salpingectomy (PS) in a pregnant bitch referred to elective video assisted ovariohysterectomy. Through celioscopy it was visualized the embryonic vesicles and PS was performed after conversion to minioceliotomy. The puppies were born by eutocic delivery without clinical alterations. The case suggested that short and regular pneumoperitoneum is not deleterious to dog fetus and video surgery could be used in pregnant bitches. PS allows the fetus development and promotes bitch neutering.(AU)

Medical management is a safe and effective alternative in most of hemodinamically stable patients. When medical treatment fails, or patient is not able to stay in observation, or ectopic/heterotopic pregnancy is diagnosed, surgical management is needed specially by laparoscopy. Regardless of the treatment, there is a high chance of success and low rate of complications. CONCLUSIONS: This update describes incidence, risk factors, diagnostic and management of tubal ectopic pregnancy. An early diagnostic and treatment are crucial to reduce complications due to this pathology.

Salpingectomía oportunista: patrones de práctica en un grupo de ginecólogos colombianos / Opportunistic Salpingectomy: patterns of practice in a group of colombian gynecologists

INTRODUCCIÓN Y OBJETIVOS: El cáncer de ovario es la neoplasia de origen ginecológico más letal y el 90% de los casos son de origen epitelial. Se ha postulado el origen del cáncer epitelial de ovario (CEO) en las fimbrias de las trompas de Falopio, por lo cual, se ha sugerido la realización de la salpingectomía oportunista como método de prevención primaria. La presente investigación tiene como objetivo determinar la frecuencia con que los ginecólogos adscritos a la Federación Colombiana de Ginecología y Obstetricia (FECOLSOG) incluyeron salpingectomías oportunistas en su práctica clínica durante los años 2017-2018. MÉTODOS: Se realizó una encuesta a los ginecólogos adscritos a la FECOLSOG. Las variables analizadas incluyeron características demográficas, práctica profesional, método de prevención primaria de cáncer de ovario en pacientes de bajo riesgo y la realización o no de la salpingectomía oportunista y sus respectivas razones. Las variables cualitativas se analizaron con frecuencias absolutas y relativas, mientras que las cuantitativas con medidas de tendencia central y desviaciones estándar con el software STATA 13. RESULTADOS: De 1765 ginecólogos contactados, 353 contestaron la encuesta (tasa de respuesta del 20%). El 62.5% de estos realizan salpingectomía oportunista en su práctica ginecológica y de estos, el 75.2% lo hizo para prevenir cáncer de ovario. Entre las razones manifestadas por los especialistas para no realizar salpingectomía oportunista, el 12.5% no la consideraba un factor de protección frente al cáncer de ovario y un 14.4% consideraba que incrementaba el riesgo de falla ovárica temprana y morbilidad asociada. CONCLUSIÓN: Aunque existen controversias en su realización, la salpingectomía oportunista muestra ser una conducta adoptada por ginecólogos adscritos a FECOLSOG. Se requieren investigaciones futuras para determinar la efectividad de la salpingectomía e implementar estrategias de prevención del cáncer epitelial de ovario.

INTRODUCTION AND OBJECTIVES: Ovarian cancer is the most lethal gynecological malignancy and 90% of cases are of epithelial origin. Recently, different investigations attribute their origin to the fimbriae of the fallopian tubes, reason why it has been suggested to perform elective salpingectomy for the prevention of high-grade adenocarcinoma, its most frequent histological variant. This research aims to determine the frequency with which gynecologists from the Colombian Federation of Gynecology and Obstetrics (FECOLSOG) included this procedure in their clinical practice during the years 2017-2018. METHODS: A survey was sent electronically to the gynecologists assigned to FECOLSOG on three different occasions with an interval of 15 days between them. The variables analyzed included demographic characteristics, professional practice, primary prevention method of Ovarian Cancer in low-risk patients and the performance or not of elective salpingectomy with their respective reasons. Qualitative variables were analyzed with absolute and relative frequencies, while quantitative variables with measures of central tendency and standard deviations with STATA 13 software. RESULTS: From 1765 gynecologists contacted at least once via email, 353 answered the survey, indicating a response rate of 20%. 62.5% perform elective salpingectomy in their gynecological practice and of these, 75.2% do so to prevent ovarian cancer. Among the reasons for not practicing salpingectomy, 12.5% ​​do not consider it a protective factor for ovarian cancer, and 14.4% believe that it increases the risk of early ovarian failure and morbidity. CONCLUSION: Elective salpingectomy is a promising procedure as a preventive measure against epithelial ovarian cancer. Although there are controversies regarding its performance, salpingectomy seems to be a common practice amongst gynecologists from FECOLSOG, and seems to have higher recurrence within this field. Future research is required to determine the effectiveness of salpingectomy and thus, implement the best strategies for ovarian cancer prevention.
