Importancia de la laparoscopia diagnóstica en la detección de implantes tumorales. Reporte de un caso / Importance of diagnostic laparoscopy in the detection of tumor implants. A case report

Resumen ANTECEDENTES: Los tumores malignos de células germinales de ovario constituyen un grupo heterogéneo de neoplasias de rápida evolución a la malignización, que suelen aparecer durante las dos primeras décadas de la vida. La prevalencia en México es de 3.4% de los tumores ováricos. El 10% de las pacientes afectadas padece dolor abdominal agudo por distención capsular, necrosis, hemorragia, rotura o torsión. CASO CLÍNICO: Paciente de 17 años, acudió al servicio de Urgencias por dolor pélvico de inicio súbito. En la laparotomía se encontró una torsión ovárica secundaria a una tumoración anexial derecha; por eso se le efectuó la salpingooferectomía. Se detectó elevada concentración de alfa-fetoproteína (10,702 ng/mL); el servicio de Oncología pediátrica indicó quimioterapia durante dos años; sin embargo, después de suspender el tratamiento persistió elevada su concentración. El ultrasonido y PET-SCAN no evidenciaron enfermedad activa. En la laparoscopia diagnóstica se observaron múltiples implantes tumorales. El reporte histopatológico fue de tumoración de senos endodérmicos. La paciente se envió, nuevamente, a Oncología pediátrica para continuar con quimioterapia y radioterapia. En la actualidad permanece estable, con descenso de la concentración de alfa-fetoproteína (última determinación: 1200 ng/mL). CONCLUSIÓN: La importancia de la laparoscopia toma relevancia en este tipo de casos, cuando existe discordancia entre los estudios bioquímicos y de imagen (ultrasonido y PET-SCAN); además, orienta hacia un diagnóstico más certero, mediante la visualización y obtención de biopsias directas, con la finalidad de establecer el tratamiento específico.

Abstract BACKGROUND: Malignant germ cell tumors of the ovary constitute a heterogeneous group of highly malignant and rapidly progressive neoplasms that usually appear during the first two decades of life. Its frequency in Mexico is 3.4% on ovarian tumors. Approximately 10% of affected patients report acute abdominal pain due to capsular distension, necrosis, hemorrhage, rupture or torsion. CLINICAL CASE: A 17 years-old patient, who went to the Emergency Department for pelvic pain of sudden onset. It was decided to perform a laparotomy and ovarian torsion was found secondary to a right adnexal tumor, so salpingo-ophorectomy was performed. High alpha-fetoprotein concentration (10.702 ng/mL) was detected; the Pediatric Oncology Service indicated chemotherapy for two years; however, after stopping the treatment, its concentration persisted. The ultrasound and PET-SCAN did not show active disease, so it was sent to the gynecological endoscopy service, where they performed diagnostic laparoscopy, observing multiple tumor implants. The histopathological results was endodermal sinus tumor. The patient was sent, again, to Pediatric Oncology to continue with chemotherapy and radiotherapy. It is currently stable, with a decrease in values of alpha-fetoprotein (last determination: 1200 ng/mL). CONCLUSION: The importance of diagnostic laparoscopy is especially relevant in this type of cases when there is disagreement between biochemical and imaging studies (ultrasound and PET-SCAN), which through laparoscopy guides us towards a more accurate diagnosis through visualization and direct biopsy taking sample and give a directed management.

The Influence of Education and Depression on Autonomy of Women with Chronic Pelvic Pain: A Cross-sectional Study / A influência da educação e depressão sobre a autonomia de mulheres com dor pélvica crônica: um estudo transversal

Objective Patient autonomy has great importance for a valid informed consent in clinical practice. Our objectives were to quantify thedomains of patient autonomy and to evaluate the variables that can affect patient autonomy in women with chronic pelvic pain. Methods This study is a cross sectional survey performed in a tertiary care University Hospital. Fifty-two consecutive women scheduled for laparoscopic management of chronic pelvic were included. Three major components of autonomy (competence, information or freedom) were evaluated using a Likert scale with 24 validated affirmatives. Results Competence scores (0.85 vs 0.92; p = 0.006) and information scores (0.90 vs 0.93; p = 0.02) were low for women with less than eight years of school attendance. Information scores were low in the presence of anxiety (0.91 vs 0.93; p = 0.05) or depression (0.90 vs 0.93; p = 0.01). Conclusions Our data show that systematic evaluation of patient autonomy can provide clinical relevant information in gynecology. Low educational level, anxiety and depression might reduce the patient autonomy in women with chronic pelvic pain.

Objetivo A autonomia da paciente é de grande importância para que o consentimento informado seja válido na prática clínica. Nossos objetivos foram quantificar os domínios da autonomia e avaliar variáveis que modificam a autonomia em mulheres com dor pélvica crônica. Métodos Este é um estudo transversal realizado em um Hospital Universitário terciário. Foram incluídas consecutivamente 52 mulheres com dor pélvica crônica agendadas para videolaparoscopia. Foi utilizada uma escala Likert com 24 afirmativas validadas para quantificar os três principais componentes da autonomia (competência, informação e liberdade). Resultados Os escores de competência (0,85 vs 0,92; p = 0,006) e informação (0,90 vs 0,93; p = 0,02) foram menores para mulheres com ensino fundamental incompleto. Os escores de informação foram menores em mulheres com sintomas de ansiedade (0,91 vs 0,93; p = 0,05) ou depressão (0,90 vs 0,93; p = 0,01). Conclusões Nossos dados mostram que a quantificação da autonomia pode produzir informações relevantes para a prática clínica em ginecologia. O nível educacional e a presença de ansiedade e depressão podem afetar a autonomia de mulheres com dor pélvica crônica.

Rol de la laparoscopia en la infertilidad inexplicada: experiencia del Hospital Clínico de la Pontificia Universidad Católica de Chile / Role of laparoscopy in unexplained infertility

Antecedentes: Existe una tendencia global creciente de no realizar laparoscopia diagnóstica en el estudio de pacientes con infertilidad inexplicada e histerosalpingografía normal. Este tipo de manejo podría tener ciertos inconvenientes dado que existen lesiones, especialmente tuboperitoneales, que no son diagnosticadas y pudiesen influir en los resultados. Nuestro grupo maneja estas pacientes con laparoscopia diagnóstica/terapéutica y posteriormente tres ciclos de inseminación intrauterina. Objetivos: Validar nuestro manejo de la infertilidad inexplicada, estimar la frecuencia de patología pélvica en pacientes con infertilidad inexplicada con histerosalpingografía normal, evaluar la tasa de embarazo posterior a la resolución laparoscópica de su patología y revisar la literatura existente. Resultados: Se revisaron todas las cirugías laparoscópicas realizadas en pacientes con infertilidad inexplicada del Hospital Clínico de la Universidad Católica, entre los años 2007-2011. De estas, 57 pacientes cumplían los criterios de inclusión y 39 recibieron al menos 1 ciclo de inseminación intrauterina posterior al procedimiento. El 82,4 por ciento de las pacientes presentaron hallazgos a la laparoscopia, siendo los más prevalentes la endometriosis grado I y II (57,8 por ciento), y las adherencias pelvianas (43,8 por ciento). De las 57 pacientes que fueron sometidas a laparoscopia diagnóstica/terapéutica, sólo 25 completaron 3 ciclos de inseminación intrauterina posterior, 8 lograron concepción (32 por ciento). Conclusión: Nuestros resultados son similares a los expuestos en otros trabajos en términos de hallazgos patológicos y tasa de fertilidad post laparoscopia. Dado el escaso acceso a técnicas de fertilización in vitro en nuestro medio, nuestro manejo plantea una excelente alternativa para este grupo de pacientes.

Background: There is an increased global tendency for avoiding a diagnostic laparoscopic surgery, among patients with unexplained infertility and a normal histerosalpingography. This decision may have certain consequences, as there may be undiagnosed lesions, such as tuboperitoneal ones, which could have an impact in the management of these patients. Our group treats them with diagnostic therapeutic laparoscopy, followed by three cycles of intrauterine insemination. Objectives: Validate our management of unexplained infertility, estimate the frequency of pelvic pathology in patients with unexplained infertility with a normal histerosalpingography, evaluate the pregnancy rate after the laparoscopic resolution of their pathology, and review the existent literature. Results: We reviewed all laparoscopic surgeries performed in patients with unexplained infertility in Hospital Clínico de la Pontificia Universidad Católica, between 2007-2011. From these, 57 patients met the inclusion criteria, and 39 of them received at least one intrauterine insemination cycle after the procedure. Laparoscopic alterations were present in 82.4 percent of the patients, being the most prevalent ones endometriosis grade I and II (57.8 percent) and pelvic adhesions (43.8 percent). Of the 57 patients who underwent laparoscopy, only 25 completed three cycles of intrauterine insemination, 8 of which conceived (32 percent). Conclusion: Our results are similar to those exposed in other series, regarding pathologic findings and fertility rate after laparoscopy. As there is limited access to advanced reproductive techniques in our country, our management represents an excellent choice for this group of patients.
