Punto G: enfoque anatómico y seguridad del paciente / G-spot: anatomical approach and patient safety

Se investiga la región uretro-vaginal (pared posterior de la uretra ­ pared anterior de la vagina), en el área que corresponde a la descripción del "punto G", con el fin de colaborar a la discusión respecto de si existe una estructura morfológica que lo identifique. Se destaca una mayor y ocasional distribución venosa en esta zona, que puede explicar el fenómeno fisiológico descrito por Gräfenberg. Para los ginecólogos, urólogos y sexólogos, el conocimiento de la anatomía funcional de esa región tiene importancia para tratar las disfunciones orgásmicas además de la incontinencia urinaria. Esta situación controvertida influye en el marco actual de la seguridad del paciente

The urethro-vaginal region (posterior wall of the urethra ­ anterior wall of the vagina) is investigated, in the area that corresponds to the description of the "G-spot", in order to contribute to the discussion regarding whether there is a morphological structure that identifies it. A greater and occasional venous distribution in this area stands out, which may explain the physiological phenomenon described by Gräfenberg. For gynecologists, urologists and sexologists, knowledge of the functional anatomy of that region is important to treat orgasmic dysfunctions in addition to urinary incontinence. This controversial situation influences the current framework of patient safety

Application and prospects of ctDNA detection in HPV associated cervical cancer / 实用医学杂志

Circulating tumor DNA(ctDNA)is a kind of cell-free DNA derived from tumors,which carries comprehensive tumor genetic information;Recent studies have found that ctDNA detection can play a role in the early diagnosis,targeted therapy,and prediction of recurrence in tumors.Human papillomavirus(HPV)-associated gynecological malignancies include most cervical cancer,some vulvar cancer,and vaginal cancer.High-risk HPV long-term infection and integration with cell genome are important causes of these cancers.Studies found that the use of ctDNA detection technology to dynamically monitor changes in HPV-ctDNA can provide valuable information for the clinical management and prognosis of these cancers.Thus,HPV-ctDNA is expected to become an biomarker for HPV-associated tumors.

Effect of CO 2 fractional laser on the structure and function of pelvic floor in female vaginal laxity / 中华医学美学美容杂志

Objective:To observe the changes of pelvic floor structure and function in female vaginal laxity after CO 2 fractional laser transvaginal treatment. Methods:This study reviewed the improvement of pelvic floor structure and function after CO 2 fractional laser transvaginal treatment in 28 female patients [aged 26-59 (37.5±8.3) years] with vaginal laxity syndrome seen at the Department of Dermatology, the First Affiliated Hospital of Air Force Medical University from March 2020 to November 2021. A total of 28 female patients with vaginal laxity syndrome underwent intravaginal treatment by CO 2 fractional laser instrument once/month for 3 times. The clinical efficacy and safety were evaluated according to the pre- and post-treatment transverse vaginal diameter, FSFI score of female sexual function, VHIS score of vaginal environment, vaginal tactile imaging system (VTI), pelvic ultrasound and MRI, tissue biopsy, patient satisfaction, pain score, and postoperative adverse effects. Results:Twenty-one of the twenty-eight female patients with vaginal laxity syndrome showed significant improvement in symptoms related to vaginal laxity syndrome after intravaginal treatment with CO 2 fractional laser therapy. All patients showed improvement in all indexes before and 1 month after treatments the mean vaginal transverse diameter decreased from (3.00±0.39) fingers to (2.71±0.40) fingers ( P<0.05), VHIS increased from (17.12±3.97) to (21.69±3.61) ( P<0.05), FSFI score improved from (23.11±3.70) to (27.43±5.33) ( P<0.05), and VTI examination showed that vaginal muscle strength and elasticity were improved to different degrees, and there was a statistical difference compared with that before treatment (total contractility of the anterior vaginal wall: t=26.23, P<0.001; total contractility of posterior vaginal wall: t=39.02, P<0.001; the mean contractility of the anterior vaginal wall: t=17.92, P<0.001; the mean contractility of the posterior vaginal wall: t=22.57, P<0.001). At the same time, questionnaire score of international consultation on incontinent questionnaire short form (ICI-Q-SF scale) of 13 patients with combined mild to moderate stress urinary incontinence showed a statistically significant decrease compared with those before treatment (8.97±2.99 before treatment and (7.18±1.79) one month after treatment; t=2.792, P<0.01). Pelvic ultrasound and magnetic resonance examination indicated a tightening of the vaginal wall structure, and pelvic ultrasound observed a significant decrease in bladder neck mobility and a significant decrease in vesicourethral rotation angle. Vaginal tissue biopsy indicated an increase in the thickness of the vaginal mucosa and an increase in the number and more regular arrangement of collagen fibers after treatment. All patients had high treatment satisfaction and there were no adverse effects such as infection and bleeding during the treatment. Conclusions:Transvaginal CO 2 fractional laser treatment can improve the pelvic floor structure and function around the vagina, treat female vaginal laxity syndrome, stress urinary incontinence and female sexual dysfunction, with significant clinical efficacy and good safety.

E-cadherin and NF-κB expression in the vagina after ovarian ischemia and reperfusion

Purpose: To investigate inflammation and cell adhesion molecules in the vagina after ovarian ischemia-reperfusion (IR) injury. Methods: 20 Wistar albino female rats were divided into two groups: control, and IR groups. In IR group, blood flow was restricted for 2 hours for ovarian ischemia. Then, tissues were re-blood 2 hours for reperfusion. Vagina tissues were excised and processed for histopathological analysis. Histopathological and biochemical follow-ups were performed. Results: Both malondialdehyde and myeloperoxidase values were increased in IR group compared to control group. Glutathione content was decreased in IR group compared to control group. Epithelial degeneration, inflammation, dilatation, and nuclear factor-κB (NF-κB) expression were increased in IR group compared to control group. E-cadherin expression was significantly decreased in IR group. In the IR group, E-cadherin showed a positive reaction in adenomas, gland-like cryptic structures, cellular junctions with clustered inflammatory cells. In the IR group, NF-κB expression was increased in basement membrane, inflammatory cells, in blood vessels. Conclusions: Ovarian ischemia caused degeneration of epithelial cells in the vaginal region and disruptions in the cell junction complex, which leads to activation of E-cadherin and NF-κB signaling pathway and alterations in reproductive and embryonal development in the vaginal region.

Variante incomum da síndrome de Herlyn- -Werner-Wunderlich: relato de caso / Unsual Herlyn-Werner-Wunderlich syndrome: case report

Malformações müllerianas correspondem a variações anatômicas do trato repro- dutor feminino. Comumente assintomáticas, o diagnóstico e a verdadeira incidên- cia são difíceis de determinar. A síndrome de Herlyn-Werner-Wunderlich, clas- sicamente descrita pela tríade útero didelfo, hemivagina cega e agenesia renal ipsilateral também pode ter variações diferentes. Em virtude da mesma origem embrionária dos tratos genital e urinário, anomalias renais devem ser investigadas nesses casos, sendo a mais comum a agenesia renal. Este artigo relata o caso de uma paciente de 18 anos, do sexo feminino, com história de piocolpo por cinco anos. Em propedêutica complementar, foi identificado útero com septação com- pleta associado a hemissepto de terço superior de vagina, formação de piocolpo e agenesia renal à direita. Apesar de não ser a definição clássica, o quadro está incluído nos casos de síndrome de Herlyn-Werner-Wunderlich.

Mullerian malformations correspond to anatomical variations of the female repro- ductive tract. Commonly asymptomatic, the diagnosis and true incidence are difficult to determine. The Herlyn-Werner-Wunderlich syndrome, classically described by the triad: uterus didelphus, blind hemivagina and ipsilateral renal agenesis, can also have different variations. Due to the same embryonic origin of the genital and urinary tracts, renal anomalies must be investigated in these cases, the most common being renal agenesis. This article reports the case of an 18-year-old female patient with a 5-year history of pyocolpus. In complementary exams, a uterus with complete septa- tion was identified, associated with a hemiseptum in the upper third of the vagina, formation of pyocolpus and renal agenesis on the right side. Despite not being the classic definition, it is included in the cases of Herlyn-Werner-Wunderlich syndrome.

Hidrocele del canal de Nuck / Hydrocele of the canal of Nuck

RESUMEN El hidrocele del canal de Nuck es una condición poco frecuente en mujeres adultas, a quienes puede causar tumefacción inguinal-vulvar. Ocurre debido al fallo de obliteración del proceso vaginal, que es la extensión del peritoneo parietal que acompaña al ligamento redondo del útero a través del canal inguinal hasta los labios mayores. La acumulación de líquido seroso en el saco provoca su aparición. Los hallazgos clínicos inespecíficos, como tumefacción indolora y fluctuante que se extiende desde el canal inguinal superficial hasta los labios mayores, no permiten realizar un diagnóstico preoperatorio de esta condición. La ecografía y la resonancia magnética pueden contribuir al diagnóstico. El diagnóstico definitivo solo puede hacerse durante la cirugía y con los hallazgos anatomopatológicos. El tratamiento consiste en la resección quirúrgica de la lesión por vía local o laparoscópica. Se presenta un caso de hidrocele del canal de Nuck.

ABSTRACT Hydrocele of canal of Nuck is a rare condition in adult women which can cause inguinal-vulvar swelling. It occurs due to failure of obliteration of the vaginal process, which is the extension of the parietal peritoneum accompanying the round ligament of the uterus through the inguinal canal to the labia majora. Accumulation of serous fluid in the sac causes its appearance. Nonspecific clinical findings such as painless, fluctuating swelling extending from the superficial inguinal canal to the labia majora do not allow a preoperative diagnosis of this condition. Ultrasonography and magnetic resonance imaging can contribute to the diagnosis. The definitive diagnosis can only be made during surgery and with anatomopathological findings. Treatment consists of surgical resection of the lesion locally or laparoscopically. A case of hydrocele of canal of Nuck is presented.

Analysis of vaginal microecology in 23 181 cases of the gynecological female outpatients / 中华妇产科杂志

Objective:To analyze the vaginal microecological status of vaginitis population and non-vaginitis population of gynecological female outpatients.Methods:A total of 30 265 women who visited the gynecological outpatient clinic of Beijing Obstetrics and Gynecology Hospital from December 2018 to December 2020 completed vaginal microecological examination. After removing the follow-up patients, 23 181 women were divided into group with symptoms and signs of vaginitis (6 697 cases) and group without symptoms and signs of vaginitis (16 484 cases), according to whether the women with symptoms and signs of vaginitis or not. And the vaginal microecological status of the two groups was compared and analyzed.Results:(1) The total detection rate of vaginitis in the initial women was 34.87% (8 083/23 181), of which 46.10% (3 087/6 697) in group with symptoms and signs of vaginitis and 30.31% (4 996/16 484) in group without symptoms and signs of vaginitis, nearly 1/3 of the gynecological outpatients without signs and symptoms of vaginitis had vaginitis. (2) Among the types of simple vaginitis, vulvovaginal candidiasis (VVC) was the most frequent in group with symptoms and signs of vaginitis (16.01%, 1 072/6 697), followed by aerobic vaginitis (AV; 12.83%, 859/6 697), with significant differences compared with group without symptoms and signs of vaginitis (all P<0.001). There were no statistical differences between the two groups of bacterial vaginosis (BV) and trichomonal vaginitis (TV), indicating that BV and TV were more likely to be neglected (all P>0.05). (3) The proportion of various combinations of vaginitis among 2 632 cases of mixed vaginitis were, in descending order: BV+AV, VVC+AV, BV+AV+VVC, AV+TV, AV+TV+BV, BV+VVC. (4) Microecological analysis of 15 098 cases diagnosed with non-vaginitis had normal flora (including those with normal flora and those with normal flora but decreased function) in 14 013 cases (92.81%, 14 013/15 098), abnormal flora in 429 cases (2.84%, 429/15 098) and the BV intermediate in 656 cases (4.34%, 656/15 098); this indicated that the vast majority of the microecological tests were normal in the vaginal microbiota of those without vaginitis. Conclusions:Microecological examination could diagnose multiple pathogenic infections at once, and is especially important as a guide for the definitive diagnosis of mixed vaginitis and vaginitis with atypical clinical symptoms. Vaginal infections such as BV and TV that are easily overlooked should be concerned.

Quemadura genital por producto químico: reporte de caso / Genital burn by chemical product: case report

Resumen ANTECEDENTES: Las quemaduras son la forma más severa de estrés que el cuerpo puede sufrir; pueden generarse por diferentes agentes térmicos y químicos. CASO CLÍNICO: Paciente de 25 años, con dolor intenso en la región genital de 12 horas de evolución, secundario a la introducción en la vagina de una piedra de alumbre. Se le hicieron múltiples irrigaciones con solución salina al 0.9% sin obtener el resto de la piedra de alumbre. Se le aplicó sulfadiazina de plata en la cavidad vaginal cada 12 horas, óvulos vaginales de ketanserina, miconazol y metronidazol cada 8 horas, ketorolaco por vía oral 10 mg cada 8 horas. Durante su estancia hospitalaria tuvo buena evolución, con disminución de la inflamación en la zona genital, epitelización adecuada. Al tercer día se dio de alta del hospital con cita para valoración a los siete días. CONCLUSIÓN: El tratamiento de las quemaduras en el área genital, por agentes químicos, tiene como piedra angular la identificación del agente causante de la lesión que permita actuar de forma inmediata y evitar las secuelas físicas, sexuales y psicológicas mediante el lavado exhaustivo con solución o agua estéril para remover el agente causal y disminuir que continúe actuando en el sitio afectado.

Abstract BACKGROUND: Burns are the most severe form of stress that the body can suffer; they can be caused by various thermal and chemical agents. CLINICAL CASE: A 25-year-old female patient presented with severe genital pain of 12 hours' duration, secondary to the introduction of an alum stone into the vagina. She underwent several irrigations with 0.9% saline without obtaining the rest of the alum stone. She was given vaginal silver sulfadiazine every 12 hours, vaginal ketanserin, miconazole and metronidazole every 8 hours and oral ketorolac 10 mg every 8 hours. During her stay in hospital, she progressed well, with a decrease in genital inflammation and adequate epithelialisation. She was discharged on the third day with an appointment for a seven-day follow-up. CONCLUSION: The management of genital burns caused by chemical agents is based on the identification of the agent causing the lesion, which allows immediate action and prevents physical, sexual and psychological sequelae by thorough washing with sterile solution or water to remove the causative agent and reduce its continued action in the affected area.

Síndrome de Hamman (neumomediastino) posparto. Síntesis de la bibliografía y reporte de caso / Postpartum Hamman (pneumomediastinal) syndrome. Synthesis of the literature and case report

Resumen ANTECEDENTES: El síndrome de Hamman se caracteriza por la coexistencia de aire libre en el mediastino sin una causa identificable; también puede ser secundario a traumatismos, infecciones intratorácicas, procedimientos médicos como la esofagoscopia y broncoscopia. Su incidencia se estima entre 1 en 2000 y 1 en 100,000 embarazos. CASO CLÍNICO: Paciente de 18 años, con 65 kg de peso, 1.56 m de talla e IMC 26.74, correspondiente a sobrepeso, primigesta, sin antecedentes patológicos ni heredofamiliares relevantes, con evolución normal del embarazo. A las 39 semanas acudió a urgencias ginecológicas debido a contractilidad uterina y salida de líquido por la vagina. La finalización del embarazo fue por parto, con recién nacido vivo. En el puerperio mediato (30 horas después del parto) súbitamente tuvo disnea, ortopnea y dolor en la región infraclavicular, sensación de "burbujeo" en la parte anterior del tórax. La radiografía simple de tórax mostró aire libre en el mediastino y enfisema subcutáneo. La TAC de tórax evidenció múltiples burbujas de aire, con extensión del espacio perivertebral de predominio derecho. La conclusión diagnóstica fue: enfisema extenso subcutáneo en los espacios del cuello, con alcance al mediastino anterior, con extenso neumomediastino y cardiomegalia global. CONCLUSIONES: El síndrome de Hamman prevalece en primigestas jóvenes y tiene un curso benigno. El tratamiento debe ser conservador, con oxígeno y analgésicos.

Abstract BACKGROUND: Hamman's syndrome is characterized by the coexistence of free air in the mediastinum without an identifiable cause; it may also be secondary to trauma, intrathoracic infections, medical procedures such as oesophagoscopy and bronchoscopy. Its incidence is estimated to be between 1 in 2000 and 1 in 100,000 pregnancies. CLINICAL CASE: 18-year-old female patient, weight 65 kg, height 1.56 m and BMI 26.74, corresponding to overweight, primigravida, with no relevant pathological or heredofamilial history, with normal evolution of pregnancy. At 39 weeks, she attended the gynaecological emergency department due to uterine contractility and leakage of fluid from the vagina. The pregnancy was terminated by delivery, with a live newborn. In the immediate postpartum period (30 hours after delivery) she suddenly experienced dyspnoea, orthopnoea and pain in the infraclavicular region, with a sensation of "bubbling" in the anterior chest. Plain chest X-ray showed free air in the mediastinum and subcutaneous emphysema. Chest CT showed multiple air bubbles, with extension of the perivertebral space predominantly on the right. The diagnostic conclusion was: extensive subcutaneous emphysema in the neck spaces extending into the anterior mediastinum, with extensive pneumomediastinum and global cardiomegaly. CONCLUSIONS: Hamman syndrome is prevalent in young primigravidae and has a benign course. Treatment should be conservative, with oxygen and analgesics.

Evisceración intestinal transvaginal incarcerada con perforación intestinal después de una colporrafia con malla. Reporte de un caso / Incarcerated transvaginal bowel evisceration with intestinal perforation after a mesh colporraphy. A case report

Introducción. La evisceración intestinal transvaginal es consecuencia, en la gran mayoría de casos, de dehiscencia del muñón vaginal posterior a histerectomía en pacientes postmenopáusicas. A través de la dehiscencia vaginal se produce la salida del contenido abdominopélvico, que puede presentarse como una evisceración simple, incarceración, obstrucción, estrangulamiento y perforación de un asa intestinal. Caso clínico. Mujer de 78 años, con antecedente inmediato de colpocleisis y colporrafia con malla de polipropileno por prolapso vaginal, que presentó dehiscencia del muñón vaginal debido a rechazo de la malla, que condicionó la solución de continuidad de la pared vaginal, con prolapso, incarceración, obstrucción y perforación de íleon. Con el diagnóstico de evisceración intestinal transvaginal incarcerada con perforación intestinal se llevó a tratamiento quirúrgico, con abordaje inicial por vía vaginal para liberar el asa intestinal, luego por laparotomía se realizó resección y anastomosis de íleon, sacrocolpopexia con malla y plastia de Douglas. Presentó buena evolución postoperatoria.Conclusión. La evisceración intestinal transvaginal con perforación intestinal es una entidad de muy rara presentación. El órgano más frecuentemente comprometido es el intestino delgado, especialmente el íleon. Puede complicarse con incarceración, obstrucción intestinal, isquemia y perforación. El manejo quirúrgico involucra resección intestinal, cuando hay signos de necrosis, con reparación y fijación del muñón vaginal.

Introduction. Transvaginal intestinal evisceration is a consequence, in the vast majority of cases, of dehiscence of the vaginal stump after hysterectomy in postmenopausal patients. Through vaginal dehiscence, the exit of the abdominopelvic content occurs, which can present as a simple evisceration, incarceration, obstruction, strangulation and perforation of an intestinal loop. Clinical case. A 78-year-old woman with an immediate history of colpocleisis and polypropylene mesh colporrhaphy due to vaginal prolapse, presents dehiscence of the vaginal stump caused by rejection of the mesh that conditioned the solution of continuity of the vaginal wall, prolapse, incarceration, obstruction and perforation of the ileum. Surgical treatment was performed with the diagnosis of incarcerated transvaginal intestinal evisceration with intestinal perforation. The initial approach was to free the intestinal loop vaginally, followed by laparotomy, ileal resection and anastomosis, mesh sacrocolpopexy, and Douglas plasty were performed. He presented good postoperative evolution.Conclussion. Transvaginal intestinal evisceration with intestinal perforation is a very rare entity. The most common organ involved is the small intestine, especially the ileum. It can be complicated by incarceration, intestinal obstruction, ischemia, and perforation. Surgical management involves intestinal resection, when there are signs of necrosis, with repair and fixation of the vaginal stump.

Dysmenorrhea due to undiagnosed obstructed hemi-vagina and ipsilateral renal anomaly syndrome can become a cause of suicide

BACKGROUND@#A Japanese woman in her early twenties had committed suicide, jumped from a 25-meter high bridge into a lake. She had been suffering from severe dysmenorrhea and general fatigue monthly.@*RESULTS@#A forensic autopsy revealed indications of a bicorporeal uterus, obstructed hemi-vagina, and ipsilateral renal agenesis, which lead to a diagnosis of obstructed hemi-vagina and ipsilateral renal anomaly (OHVIRA) syndrome. On the right side of the uterus, an enclosed cavity composed of black clots was observed. Histological findings suggested that her endometrium was in the early proliferative phase, implying that she was in the menstrual phase just before her death. She may have been suffering from severe lower abdominal pain from the increased pressure of the closed uterus cavity.@*CONCLUSIONS@#This case indicates that dysmenorrhea from undiagnosed OHVIRA syndrome can possibly lead to a suicide attempt. In Japan, because suicide was the leading cause of death for people aged 15 to 39 in 2019, preventive measures for suicide should be promoted. The present case also suggests that intervention for dysmenorrhea may prevent this in adolescent woman.

Advances in the application of transvaginal ultrasound in the diagnosis and treatment of ectopic pregnancy / 中国基层医药

Ectopic pregnancy is one of the most common acute abdominal diseases in gynecology. A ruptured ectopic pregnancy can lead to hemorrhagic shock, which is life-threatening. Therefore, early diagnosis and early treatment are extremely critical for preserving fertility and achieving good prognosis in patients with ectopic pregnancy. The available diagnostic methods of ectopic pregnancy include laboratory tests such as progesterone test, human chorionic gonadotropin test and ultrasound examination. Ultrasound examination can help determine the location of uterine and adnexal masses, gestational sacs, and germ, all of which are directly related to the final diagnosis regarding ectopic pregnancy. Ultrasound examination includes abdominal ultrasound and transvaginal ultrasound. Transvaginal ultrasound accesses to the focal tissue closer than abdominal ultrasound, and it does not require a full bladder. These advantages make clinical practice of transvaginal ultrasound easier for both physicians and patients. However, application of transvaginal ultrasound in the diagnosis of ectopic pregnancy requires further investigation to guide the early diagnosis and treatment of ectopic pregnancy. .

Dynamics of vaginal microbiota in women of reproductive age during the menstrual cycle / 中华妇产科杂志

Objective:To investigate the dynamic changes of vaginal microbiota in different phases of menstrual cycle in healthy Chinese women of childbearing age.Methods:A total of 11 healthy women of childbearing age with regular menstruation, who had physical examination in the Gynecology Clinic of Beijing Obstetrics and Gynecology Hospital from September to December 2020 were randomly selected as research subjects. Vaginal secretions were collected during menstrual phase (2nd-3rd day), mid-follicular phase (7th-8th day), and mid-luteal phase (21st-22nd day) for microbiota analysis through metagenomic sequencing.Results:(1) Vaginal microbiota species were the most diverse in menstrual phase and the least in follicular phase, observing dominant vaginal bacteria gradually changing to Lactobacillus from menstrual phase to follicular phase and then to luteal phase. (2) The dynamic evolution of vaginal microbiota from menstrual phase to follicular phase and then to luteal phase was divided into: no change in dominant bacteria, replacement of dominant bacteria, changes in the proportion of dominant bacteria, and recurrence of dominant bacteria (non-Lactobacillus-dominance appeared again in luteal phase after returning to normal Lactobacillus-dominance in follicular phase). (3) Prevotella, especially Prevotella_bivia, was significantly higher during menstrual phase.Conclusions:Healthy vaginal microbiota should be relatively stable, but also have the ability of dynamic change and self-recovery. Prevotella plays a central role among opportunistic pathogens in the vagina, whose function remains to be investigated.

Analysis of the safety and efficacy of transvaginal natural orific transluminal endoscopic adnexectomy in elderly women / 中华老年医学杂志

Objective:To investigate the feasibility and safety of transvaginal natural orific transluminal endoscopic surgery(vNOTES)in elderly women with adnexectomy.Methods:Using a prospective randomized controlled study method, 90 patients with benign ovarian tumors who met the study inclusion criteria and were treated in the Department of Gynecology of Beijing Hospital from January 2019 to December 2021 were randomly assigned to the experimental group(vNOTES group)according to 1∶1.The conventional laparoscopy group(CL group)and the control group underwent ovarian cystectomy.Preoperative baseline conditions, surgical success rate, operation time, intraoperative blood loss, postoperative complications, visual analogue scale(VAS)within 24 hours and one week after operation, postoperative scar score, and postoperative sexual function score were compared between the two groups.and other related data.Results:The operation of 90 patients was successfully completed, and there was no intraoperative and postoperative complications.There were no significant differences in preoperative general condition, operation time, intraoperative blood loss, health status score and sexual function evaluation between the two groups( P>0.05).The peak airway pressure of mechanical ventilation(21.9±1.8)cmH 2O(1 cmH 2O=0.098 kPa), end-expiratory CO 2 partial pressure(36.6±1.4)mmHg(1 mmHg=0.133 kPa), postoperative exhaust time(8.8±1.7)h, and VAS pain score within 24 hours after surgery(1.3±1.2 points)and scar scores at 1 month, 3 months and 6 months after surgery(1.7±1.1、0.4±0.3、0.0±0.0)were all lower than the control group(29.7±2.6)cmH 2O; (39.9±2.0)mmHg; (21.9±2.7)h; 4.6±2.8、6.5±2.0、4.0±1.6、2.5±1.0), ( P<0.01). 6 months after the operation, the health condition score of the experimental group(124.8±10.6)was higher than that of the TL group.(119.9±10.7)points( P<0.05). Conclusions:For elderly women, transvaginal laparoscopic adnexectomy is safe and feasible, with unique advantages such as less impact on cardiopulmonary function, less pain, less scarring, and faster physical recovery.It is a more minimally invasive method of surgery.It can be used as a surgical modality for adnexectomy in older women.

Resección de fístula vesico-vaginal por vía laparoscópica, con abordaje extravesical

La fístula vesico-vaginal es la fístula adquirida más común de las vías urinarias; su principal manifestación es la salida de orina por vía transvaginal. Una fístula representa una comunicación anormal entre dos superficies epitelizadas. La clasificación de fístulas se basa en el órgano de origen en el tracto urinario y el punto de terminación de la fístula. La incontinencia urinaria debida a la formación de una fistula supone un importante problema higiénico, psicológico y social para la paciente, debido a la continua sensación de humedad, olores indeseables, infecciones vaginales, vesicales y a la incapacidad laboral y social que le condiciona. Paciente de 44 años de edad, antecedente de histerectomía, por dismenorrea y miomas uterinos, con pérdida de orina transvaginal 4 semanas posteriores a la cirugía, se realiza reparación de fistula 4 meses posteriores a su cirugía, se realiza por abordaje laparoscópico transperitoneal, por 4 puertos, con un seguimiento a 6 meses, con resolución completa, sin recurrencia, con sangrado mínimo, actualmente sin catéteres, con función genital y urinaria normal, con adecuada continencia urinaria. El abordaje laparoscópico es una excelente alternativa, aunque se requiere experiencia en cirugía laparoscópica pélvica, con el beneficio para el paciente, de recuperación rápida, con menor dolor y sangrado, por esto creemos que con practica y paciencia es perfectamente realizable este tipo de abordaje.

The vesicovaginal fistula is the most common acquired fistula of the urinary tract; its main manifestation is the release of urine through the vagina. A fistula represents an abnormal communication between two epithelialized surfaces. The classification of fistulas is based on the organ of origin in the urinary tract and the end point of the fistula. Urinary incontinence due to the formation of a fistula is a major hygienic, psychological, and social problem for the patient, due to the continuous feeling of moisture, unpleasant odors, vaginal and bladder infections, and the inability to work and socialize that it conditions. The patient is 44 years old, with a history of hysterectomy for dysmenorrhea and uterine fibroids, with loss of vaginal urine 4 weeks after surgery, a repair of the fistula is performed 4 months after surgery, using a laparoscopic transperitoneal approach through 4 ports, with a follow-up at 6 months, with complete resolution, without recurrence, with minimal bleeding, currently without catheters, with normal genital and urinary function, with adequate urinary continence. Laparoscopic approach is an excellent alternative, although it requires experience in pelvic laparoscopic surgery, with the benefit for the patient of rapid recovery, with less pain and bleeding, which is why we believe that with practice and patience this type of approach is perfectly feasible.

Reconstrucción cervical con conexión vaginal secundaria a agenesia cervical. Reporte de caso / Cervical reconstruction with vaginal conexion secundary to cervical agenesia. Case report

Resumen ANTECEDENTES: La agenesia cervical congénita es una anomalía poco común del sistema de Müller, que generalmente se reconoce durante la menarquia. Hasta hace poco, el tratamiento de primera elección era la histerectomía, debido a que no se consideraba una enfermedad compatible con la fertilidad. Hoy en día, gracias a las técnicas de reproducción asistida, se han desarrollado procedimientos quirúrgicos menos agresivos que sí preservan la fertilidad de las pacientes. OBJETIVO: Revisar un caso de agenesia cervical a partir de su tratamiento quirúrgico y seguimiento de la reconstrucción cervical con la conexión entre la vagina y el útero, revisar la bibliografía y cómo establecer el pronóstico a largo plazo. CASO CLÍNICO: Paciente de 12 años llevada a consulta ante la ausencia de menstruación. El procedimiento diagnóstico transcurrió sin que se encontraran alteraciones; sin embargo, en la laparoscopia diagnóstica operatoria efectuada a los 14 años, indicada por dolor pélvico cíclico, se advirtieron la ausencia del cuello del útero, un hematometra y endometriosis grado IV. En el segundo tiempo quirúrgico, practicado en conjunto con el cirujano pediatra, se practicó, por laparotomía, la comunicación entre el útero y la vagina. En la actualidad, la paciente tiene 19 años y sus menstruaciones son cíclicas, no dolorosas. En el último ultrasonido se visualizó la conexión entre el útero y la vagina. CONCLUSIONES: Hoy en día, la anastomosis útero vaginal es un procedimiento capaz de mantener la función del útero y permitir el embarazo, con los cuidados adecuados.

Abstract BACKGROUND: Congenital cervical agenesis is a rare anomaly of the Müllerian system, usually recognized during menarche. Until recently, the treatment of first choice was hysterectomy, because it was not considered a disease compatible with fertility. Today, thanks to assisted reproductive techniques, less aggressive surgical procedures have been developed that do preserve the fertility of patients. OBJECTIVE: To review a case of cervical agenesis from its surgical treatment and follow-up cervical reconstruction with the connection between the vagina and the uterus, review the literature and how to establish the long-term prognosis. CLINICAL CASE: A 12 years old female patient was brought for consultation due to absence of menstruation. The diagnostic procedure was carried out without finding any alterations; however, in the operative diagnostic laparoscopy performed at the age of 14, indicated by cyclic pelvic pain, the absence of the cervix, a hematometra and endometriosis grade IV were noticed. In the second surgery, performed in conjunction with the pediatric surgeon, the communication between the uterus and the vagina was performed by laparotomy. At present, the patient is 19 years old and her menses are cyclical, not painful. In the last ultrasound the connection between the uterus and the vagina was visualized. CONCLUSIONS: Today, utero-vaginal anastomosis is a procedure capable of maintaining the function of the uterus and allowing pregnancy, with proper care.

Síndrome de Herlyn-Werner-Wunderlich: reporte de caso y revisión de la literatura / Herlyn-Werner-Wunderlich syndromne: case review and report of the literatura

RESUMEN Objetivo: Presentar un reporte de caso de síndrome de Herlyn Werner Wunderlich (SHWW) y hacer una revisión de la literatura para determinar los hallazgos clínicos e imagenológicos en estas pacientes. Materiales y métodos: Se presenta el caso de una mujer de 16 años que consultó, en un hospital de las fuerzas militares en Bogotá, por dolor pélvico recurrente, su diagnostico final fue SHWW. Se realizó una búsqueda sistemática de la literatura en las diferentes bases de datos, revisiones sistemáticas, cohortes, series de casos y reportes de casos en pacientes con diagnóstico de SHWW en cualquier edad, se obtuvo información sobre las características de presentación clínica, y las tecnologías diagnósticas más frecuentemente utilizadas. Se hace resumen narrativo de los hallazgos. Resultados: Se incluyeron 77 publicaciones, un total de 676 pacientes. Los síntomas más frecuentes fueron dismenorrea (63,9 %), seguido de dolor pélvico (35,2%). Las tecnologías diagnósticas más utilizadas fueron el ultrasonido pélvico en un 92,1% y la resonancia magnética nuclear en un 74,6% de los casos. La histeroscopia y laparoscopia son poco utilizados en el diagnóstico. Conclusión: El SHWW es una entidad poco frecuente, debe hacer parte del estudio complementario de la agenesia renal del paciente pediátrico y del diagnóstico diferencial de la dismenorrea primaria en pacientes en la adolescencia. Se requiere evaluar con estudios de cohorte más grandes la utilidad de la histeroscopia en estas pacientes.

ABSTRACT Objective: To report a case of Herlyn-Werner-Wunderlich syndrome (HWWS) and conduct a review of the literature to determine clinical and imaging findings in these patients. Material and methods: A 16-year-old female patient who presented to a military hospital in Bogota complaining of recurrent pelvic pain, receiving a final diagnosis of HWWS. A systematic search was conducted in the different databases of systematic reviews, cohort studies, case series and case reports of patients of any age diagnosed with HWWS. Clinical presentation characteristics and the most frequent diagnostic technologies used were obtained. A narrative summary of the findings is presented. Results: Overall, 77 publications with a total of 676 patients were included. The most frequent symptom was dysmenorrhea (63.9%), followed by pelvic pain (35.2%). The most frequently used diagnostic technologies were pelvic ultrasound in 92.1% of cases and nuclear magnetic resonance in 74.6%. Hysteroscopy and laparoscopy are seldom used for diagnosing this condition. Conclusion: HWWS is an infrequent disease condition. It must be part of the work-up for renal agenesis in pediatric patients and of the differential diagnosis in primary dysmenorrhea in adolescence. The role of hysteroscopy in this condition must be further assessed in larger cohort studies.

Leiomioma de cúpula vaginal posterior a histerectomía. Reporte de caso / Vaginal vault leiomyoma after hysterectomy. Case report

RESUMEN Los leiomiomas son tumores benignos, mesenquimales que generalmente surgen de las células del músculo liso uterino, pero también pueden aparecer en sitios atípicos como vagina, pulmones y estructuras vasculares. Los leiomiomas de cúpula vagina posterior a la histerectomía son muy raros y su etiología no ha sido determinada. La ecografía transvaginal, tomografía computarizada y la resonancia magnética son herramientas útiles para el diagnóstico y seguimiento de estas pacientes. El tratamiento definitivo es la extirpación total del tumor para evitar la diseminación o derrame inadvertido de células neoplásicas malignas ocultas. La administración de análogos de la hormona liberadora de gonadotropina o la embolización intravascular pueden ser métodos alternativos para reducir la pérdida hemática intraoperatoria. Se presenta un caso de leiomioma de cúpula vaginal posterior a histerectomía.

ABSTRACT Leiomyomas are benign, mesenchymal tumors that usually arise from uterine smooth muscle cells, but can also occur in atypical sites such as the vagina, lungs and vascular structures. Post-hysterectomy vaginal vault leiomyomas are very rare and their etiology has not been determined. Transvaginal ultrasound, computed tomography and magnetic resonance imaging are useful tools for the diagnosis and follow-up of these patients. The definitive treatment is total removal of the tumor to avoid dissemination or inadvertent spillage of occult malignant neoplastic cells. Administration of gonadotropin-releasing hormone analogs or intravascular embolization may be alternative methods to reduce intraoperative blood loss. A case of vaginal vault leiomyoma following hysterectomy is presented.
