Introducción: El cáncer ha causado más muertes que todas las guerras y catástrofes conocidas. En particular, el cáncer de mama se ha convertido en una pandemia que amenaza con seguir propagándose. Objetivo: Describir las diferencias en cuanto a los resultados obtenidos de la cirugía conservadora y radical como tratamiento del cáncer de mama. Métodos: Se realizó un estudio analítico, observacional, descriptivo y retrospectivo en un universo de 177 pacientes con diagnóstico de cáncer de mama en el servicio de Cirugía General del Centro de Investigaciones Médico Quirúrgicas de La Habana, Cuba. Todas recibieron tratamiento quirúrgico en el período comprendido de enero de 2011 a diciembre de 2016. Resultados: De las pacientes estudiadas, el 92,09 por ciento no presentaron antecedentes de patología mamaria, mientras que el 36,72 por ciento tuvieron como antecedente patológico familiar cáncer de mama. Predominaron las pacientes mayores de 70 años en ambas técnicas quirúrgicas. En el grupo de 30-40 años solamente se practicaron técnicas conservadoras. Con respecto al estadiamiento, predominó la etapa II de la enfermedad. La sobrevida global a los 5 años fue superior al 90 por ciento, mientras que el intervalo libre de enfermedad se mantuvo en valores similares para ambas técnicas. Conclusiones: Se realizaron mayor número de cirugías conservadoras de mama en pacientes que se encontraban en etapas clínicas más tempranas de la enfermedad y la sobrevida global de los procedimientos conservadores fue ligeramente mayor(AU)

Introduction: Cancer has caused more deaths than all known wars and catastrophes. Particularly speaking, breast cancer has become a pandemic that threatens to continue to spread. Objective: To describe the differences based on the results obtained from conservative and radical surgery as a treatment for breast cancer. Methods: An analytical, observational, descriptive and retrospective study was carried out with a universe of 177 female patients diagnosed with breast cancer in the general surgery service of Centro de Investigaciones Médico Quirúrgicas, of La Habana, Cuba. All of them received surgical treatment in the period from January 2011 to December 2016. Results: 92.09 percent of the patients studied had no history of breast pathology, while 36.72 percent had breast cancer as a family pathological history. Patients over 70 years of age predominated in both surgical techniques. In the group of 30-40 years of age only conservative techniques were performed. With respect to staging, there was a predominance of the disease in stage II. Overall survival at 5 years was higher than 90 percent, while the disease-free interval remained at similar values for both techniques. Conclusions: A greater amount of breast-conserving surgeries were performed in patients at earlier clinical stages of the disease, while overall survival of conservative procedures was slightly higher(AU)

Conclusions: Overall survival is higher in patients with infiltrating ductal carcinoma (not otherwise specified), tumor stages IA and IIA, molecular subtype Luminal B according to immunohistochemistry, and definitive treatments with chemotherapy, radiotherapy, hormone therapy scheme(AU)

Osteomielitis en el pie diabético. Tratamiento médico y cirugía conservadora. Experiencia en la Unidad de Pie / Diabetic foot osteomyelitis. Medical treatment and conservative surgical approach in a Diabetic Foot Unit / Osteomielite em pé diabético. Tratamento clínico e cirurgia conservadora. Experiência na Unidade do Pé

Resumen: La complicación más frecuente de la úlcera del pie diabético (UPD) es la infección, siendo el desencadenante principal de amputaciones menores y mayores. La osteomielitis (OM) está presente hasta en el 60% de los casos y su tratamiento es un desafío, generando controversias según las formas clínicas de presentación. La resección del hueso infectado ha sido el tratamiento estándar, pudiendo generar secuelas funcionales y úlceras recurrentes. En las últimas dos décadas se propuso el tratamiento antimicrobiano con cirugía conservadora o sin cirugía en las lesiones del antepie, con resultados satisfactorios. Objetivo: presentar los resultados del tratamiento médico de la osteomielitis del pie en pacientes diabéticos, priorizando resecciones mínimas que eviten amputaciones desestabilizantes de su biomecánica. Se evaluaron seis pacientes con diabetes mellitus (DM) tratados en la Unidad de Pie, con osteomielitis de falanges, metatarsianos y calcáneo, tratados con antibióticos durante 7±2 semanas y con resecciones limitadas al antepié, con buena evolución. Durante un año de seguimiento hubo ausencia de cualquier signo de infección en el sitio inicial o contiguo de la lesión, preservando el apoyo. Conclusión: la cirugía con resección mínima sin amputación local o de alto nivel tiene éxito en casos seleccionados de osteomielitis del pie diabético. Deben realizarse ensayos prospectivos para determinar sus beneficios frente a otros enfoques.

Abstract: Infection is the most frequent complication in diabetic foot ulcers, and it is the main cause of minor and major lower extremities amputations. Osteomyelitis accounts for 60% of cases and it constitutes a challenge when it comes to treatment, since controversies arise depending on its clinical presentation. Resection of the infected bone has been the golden standard, despite it may cause functional sequelae and recurring ulcers. In the last two decades antibiotic therapy has emerged, combined with a conservative surgical approach or no surgery in forefoot lesions, the results being satisfactory. Objective: to present the results of medical treatment of foot osteomyelitis in diabetic patients, prioritizing minimal resections that avoid amputations which alter the biomechanics of the foot. The study evaluated 6 diabetic patients assisted at the Diabetic Foot Unit, with phalanx, metatarsal and calcaneal osteomyelitis. They received antibiotic therapy for 7 ± 2 weeks and resections were limited to the forefoot, showing good evolution. During a one-year follow-up, there were no signs of infection in the initial site or adjacent to the lesion, support of the foot being preserved. Conclusion: minimum resection surgery with no local or major amputation is a successful therapy in selected cases of diabetic foot osteomyelitis. Prospective trials are necessary to determine benefits of this management when compared to other approaches.

Resumo: A complicação mais frequente da úlcera do pé diabético (UFD) é a infecção, sendo o principal desencadeador de amputações menores e maiores. A osteomielite (OM) está presente em até 60% dos casos e seu tratamento é um desafio, gerando controvérsias dependendo de suas formas clínicas de apresentação. A ressecção do osso infectado tem sido o tratamento padrão, podendo gerar sequelas funcionais e úlceras recorrentes. Nas últimas duas décadas, o tratamento antimicrobiano com cirurgia conservadora ou sem cirurgia tem sido proposto nas lesões do antepé, com resultados satisfatórios. Objetivo: apresentar os resultados do tratamento clínico da osteomielite do pé em pacientes diabéticos, priorizando ressecções mínimas que evitem amputações desestabilizadoras de sua biomecânica. Foram avaliados seis pacientes diabéticos (DM) atendidos na Unidade do Pé, com osteomielite de falanges, metatarsos e calcâneo, tratados com antibióticos por 7±2 semanas e ressecções limitadas ao antepé com boa evolução. Durante um ano de seguimento, não houve sinais de infecção no local inicial ou contíguo da lesão, preservando o suporte. Conclusão: a cirurgia com ressecção mínima sem amputação local ou de alto nível é bem-sucedida em casos selecionados de osteomielite do pé diabético. Ensaios prospectivos devem ser realizados para determinar os benefícios desta em relação a outras abordagens.

Intraoperative Assessment of Endogenous Microbiota in the Breast / Avaliação intraoperatória da microbiota endógena da mama

Abstract Objective: Breast surgery is considered a clean surgery; however, the rates of infection range between 3 and 15%. The objective of the present study was to intraoperatively investigate the presence of autochthonous microbiota in the breast. Methods: Pieces of breast tissue collected from 49 patients who underwent elective breast surgery (reconstructive, diagnostic, or oncologic) were cultured. The pieces of breast tissue were approximately 1 cm in diameter and were removed from the retroareolar area, medial quadrant, and lateral quadrant. Each piece of tissue was incubated in brain heart infusion (BHI) broth for 7 days at 37°C, and in cases in which the medium became turbid due to microorganism growth, the samples were placed in Petri dishes for culturing and isolating strains and for identifying species using an automated counter. Results: Microorganism growth was observed in the samples of 10 of the 49 patients (20.4%) and in 11 of the 218 pieces of tissue (5%). The detected species were Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Sphingomonas paucimobilis, and Aeromonas salmonicida. No patient with positive samples had clinical infection postoperatively. Conclusion: The presence of these bacteria in breast tissue in approximately 20% of the patients in this series suggests that breast surgery should be considered a potential source of contamination that may have implications for adverse reactions to breast implants and should be studied in the near future for their oncological implications in breast implant-associated large-cell lymphoma etiology.

Resumo Objetivo: A cirurgia de mama é considerada uma cirurgia limpa; entretanto, as taxas de infecção variam entre 3 e 15%. O objetivo deste estudo foi investigar no intraoperatório a presença de microbiota autóctone na mama. Métodos: Pedaços de tecido mamário coletados de 49 pacientes submetidas à cirurgia eletiva da mama (reconstrutiva, diagnóstica ou oncológica) foram cultivados. Os pedaços de tecido mamário tinham aproximadamente 1 cm de diâmetro e foram removidos da área retroareolar e dos quadrantes medial e lateral. Cada pedaço de tecido foi incubado em caldo BHI (brain heart infusion) por 7 dias a 37 ° C, e nos casos em que o meio ficou turvo devido ao crescimento de microrganismos, as amostras foram colocadas em placas de Petri para cultivo e isolamento de cepas e para identificação de espécies usando um contador automatizado. Resultados: O crescimento do microrganismo foi observado nas amostras de 10 das 49 pacientes (20,4%) e em 11 dos 218 pedaços de tecido (5%). As espécies detectadas foram Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Sphingomonas paucimobilis e Aeromonas salmonicida. Nenhum paciente com amostras positivas apresentou infecção clínica no pós-operatório. Conclusão: A presença dessas bactérias no tecido mamário em aproximadamente 20% das pacientes desta série sugere que a cirurgia mamária deve ser considerada uma fonte potencial de contaminação que pode ter implicações nas reações adversas aos implantes mamários e deve ser estudada em um futuro próximo por suas implicações oncológicas na etiologia do linfoma de células grandes associado ao implante de mama.

Intraoperative ultrasound leads to conservative management of benign ovarian tumors: A retrospective, single-center study / Ultrassom intraoperatório leva ao manejo conservador de tumores ovarianos benignos: Um estudo retrospectivo e monoinstitucional

Abstract Objective To evaluate whether the use of intraoperative ultrasound leads to more conservative surgeries for benign ovarian tumors. Methods Women who underwent surgery between 2007 and 2017 for benign ovarian tumors were retrospectively analyzed. The women were classified into two groups: those who underwent intraoperative ultrasound (group A) and those who did not (group B). In group A, minimally-invasive surgery was performed for most patients (a specific laparoscopic ultrasound probe was used), and four patients were submitted to laparotomy (a linear ultrasound probe was used). The primary endpoint was ovarian sparing surgery (oophoroplasty). Results Among the 82 cases identified, only 36 met the inclusion criteria for the present study. Out of these cases, 25 underwent intraoperative ultrasound, and 11 did not. There were no significant differences in arterial hypertension, diabetes, smoking history, and body mass index for the two groups (p=0.450). Tumor diameter was also similar for both groups, ranging from 1 cm to 11 cm in group A and from 1.3 cm to 10 cm in group B (p=0.594). Tumor histology confirmed mature teratomas for all of the cases in group B and for 68.0% of the cases in group A. When the intraoperative ultrasound was performed, a more conservative surgery was performed (p<0.001). Conclusion The use of intraoperative ultrasound resulted in more conservative surgeries for the resection of benign ovarian tumors at our center.

Resumo Objetivo Avaliar se o uso do ultrassom intraoperatório leva a cirurgias mais conservadoras para tumores ovarianos benignos. Métodos Mulheres que foram submetidas a cirurgia entre 2007 e 2017 por tumores ovarianos benignos foram analisadas retrospectivamente. As mulheres foram classificadas em dois grupos: aquelas que foram submetidas ao ultrassom intraoperatório (grupo A), e aquelas que não o foram (grupo B). No grupo A, foi realizada cirurgia minimamente invasiva na maioria das pacientes (foi usada sonda ultrassonográfica laparoscópica específica), e quatro pacientes foram submetidas a laparotomia (foi usada sonda ultrassonográfica linear). O desfecho primário foi a cirurgia preservadora do ovário (ooforoplastia). Resultados Entre os 82 casos identificados, somente 36 atenderam aos critérios de inclusão para este estudo. Destes, 25 pacientes foram submetidas ao ultrassom intraoperatório, e 11 não o foram. Não houve diferenças significantes em relação à pressão arterial, diabetes, tabagismo e índice de massa corporal entre os dois grupos (p=0.450). O diâmetro do tumor também foi similar entre os dois grupos, variando de 1cm a 11cm no grupo A, e de 1,3cma 10cm no grupo B (p=0.594). A histologia dos tumores confirmou teratoma maduro para todos os casos do grupo B, e para 68,0% dos casos do grupo A. Mais cirurgias conservadoras foram realizadas quando o ultrassom intraoperatório foi realizado (p<0.001). Conclusão O uso do ultrassom intraoperatório resultou em mais cirurgias conservadoras na ressecção de tumores benignos do ovário em nossa instituição.

Obliterative le fort’s colpocleisis for acute kidney injury caused by pelvic organ prolapse in elderly woman

Pelvic organ prolapse (POP) is the descent of pelvic organs through the vagina, which sometimes causes hydronephrosis. Here authors report a case of an eighty five year old woman with a fourth degree uterine prolapse with obstructive uropathy. She was treated with a conservative surgery Le Fort’s colpocleisis. Following which the patient’s renal functions and symptoms improved. Hence authors conclude that colpocleisis can be considered as the option for elderly women who have completed the family with no desire to preserve the sexual function especially in women with co morbities where pelvic reconstructive surgeries pose a challenge.

Transformation of fibroadenoma to phyllodes tumor and the use of oncoplastic technique for breast conservative treatment / A transformação do fibroadenoma em tumor filóides e o uso de técnicas oncoplásticas no tratamento cirúrgico conservador de mama

Phyllodes tumors (PT) are rare neoplasms accounting for <1% of breast lesions. A transformation of a fibroadenoma (FA) to a PT is even more rare and unpredictable. Many challenges face PT management, since diagnostic through surgical treatment. We describe a case of a 63-year old woman with PT that was previously diagnosed as a FA who underwent an oncoplastic conservative surgery. A review of the literature on the diagnostic and surgical management of PT was performed. The diagnostic of PT can be hard mostly in needle biopsy, and the close follow up of negative lesions is recommended. Oncoplastic techniques might be an important tool on the conservative treatment of these patients.

O tumor filoide (TF) é uma rara neoplasia que corresponde a menos de 1% das lesões mamárias. A tranformação do fibroadenoma (FA) em TF é um evento raro e imprevisível. Existem muitos desafios no manejo dos TF, desde o seu diagnóstico ao tratamento. Nós descrevemos o caso de uma paciente de 63 anos com TF com diagnóstico prévio de FA que foi submetida ao tratamento cirúrgico conservador da mama por técnicas oncoplásticas. Uma revisão da literatura sobre o diagnóstico e tratamento do TF foi realizada. O diagnóstico dessa condição pode ser especialmente difícil quando feito a partir de amostra de biópsias por agulha, e em caso de resultados negativos recomenda-se acompanhamento rigoroso. As técnicas oncoplásticas podem ser uma importante ferramenta no tratamento cirúrgico conservador desses pacientes.

Cases of management of paediatric tubo-ovarian torsion

Ovarian torsion is the fifth most common cause of gynaecologic surgical emergency. It warrants early diagnosis as timely surgical management will avoid the further adnexal injury. In paediatric population, this is especially dangerous as the condition can go undiagnosed because of its rarity and nonspecific presentation. This leads to delay in surgical exploration and loss of ovarian function. In these cases, the ovary and often the ipsilateral fallopian tube twist with the vascular pedicle, resulting in vascular compromise. Unrelieved torsion leads to haemorrhagic infarction. We encountered 3 cases of ovarian torsion in paediatric age group during a period of 12 months. All cases presented with acute pain abdomen for 3-7 days period with loss of appetite and unable to pass motion with varied disappearance of pain. On ultrasound all the cases were diagnosed with ovarian cyst with torsion and underwent laparoscopic cystectomy. This case series is written just to show the results of de-torsion and conserving the fallopian tube and ovary after vascular damage. This type of conservative management may give chance to ovary to return to viability. This was seen in all 3 cases dealt by us on repeat scan on follow up. Even on de-torsion if ovary does not regain its colour immediately it should be conserved, and cystectomy should be performed rather than oophorectomy. Conservative surgery, in the form of ovarian de-torsion can be tried in cases of ischemia but if ovarian necrosis has occurred, then salpingo-oophorectomy is performed as the last resort.

Conservative Surgery for a young nulligravid with ovarian yolk sac tumor and concurrent contralateral mature teratoma

@#<p>Ovarian cancer is the second most common gynecologic cancer worldwide and the six most common cancer among females. Germ cell tumorbs are the most common ovarian neoplasm in the first two decades of life constituting approximately two-thirds of all ovarian tumors. Malignant germ cell tumors constitute one-third of germ cell origin tutors and two-thirds of all ovarian malignancy in this age-group. This paper presents a case of a 19 year-old nulligravid who presented at the emergency room with abdominal pain, and was intraoperatively diagnosed with yolk sac tutor of the right ovary, stage 1A mature cystic teratoma of the left ovary. She subsequently underwent unilateral salpingooophorectomy and contralateral oophorocystectomy, left. Patient is advised chemotherapy postoperatively, with Bleomycin, Etoposide and Paclitaxel. This paper discusses the incidence, risk factors, prognosis and management of yolk of sac tutor in a young nulligravid.</p>

Multivariate analysis of laparoscopic conservative surgery for persistent ectopic pregnancy after tubal pregnancy / 中国综合临床

Objective To investigate the influencing factors of persistent ectopic pregnancy (PEP) after laparoscopic conservative surgery for tubal pregnancy.Methods Three hundred and one cases of tubal pregnancy treated by laparoscopic conservative surgery in Jizhong energy Fengfeng Group Hospital from October 2007 to October 2017 were divided into PEP group ( 21 cases) and non PEP group ( 280 cases) according to whether PEP occurred after operation.The age,menopause time and preoperative serum of the two groups were analyzed.The levels of beta?human chorionic gonadotropin (beta?hCG),surgical methods, corpus luteum exfoliation, methotrexate and mass diameter were analyzed.Logistic regression was used to analyze the multiple factors.Results There was no significant difference in age between the two groups.There were significant differences in the time of menopause, preoperative serum beta?hCG level, operative methods,corpus luteum exfoliation, methotrexate application and mass diameter between the two groups (P＜0.05 or P＜0.01).Multivariate logistic regression analysis showed that short menopause time, high preoperative serum beta?hCG concentration, sac extrusion at the umbrella end of fallopian tube, no corpus luteum exfoliation, no intraoperative methotrexate and small mass diameter were risk factors for persistent ectopic pregnancy (OR(95%CI) were 1.476 ( 1.035～3.961),1.513 (1.391～3.017),5.301 (1.304～19.570),1.104 (1.015～2.769),1.180 (1.020～2.543),1.540 (1.181～5.120),respectively, all P＜0.05).Conclusion PEP is prone to occur in patients with tubal pregnancy treated by laparoscopic conservative surgery,such as short menopause time,small size of mass,high preoperative serum beta?hCG concentration,no corpus luteum exfoliation,no local methotrexate and umbrella sac extrusion.Therefore,the key measures to reduce the occurrence of PEP in clinic are to choose the right operation time,appropriate operation method,corpus luteum exfoliation and local injection of methotrexate.

Impact of adenomyosis on fertility and the choice of management / 中国实用妇科与产科杂志

Adenomyosis has high prevalence in infertility women,deteriorating the pregnancy results of in vitro fertilization therapy for couples with or without pelvic endometriosis.The mechanisms of effect include:anatomical distortion,uterine dysperistalsis,altered implantation environment,intrauterine free radicals excess and overactive immune system,etc.Assisted reproductive technology is an effective measure to improve the pregnancy outcome,and conservative surgery adds up some natural conception while alleviating the symptoms.Obstetric complications should be taken into account before cytoreductive surgery.Gonadotropin releasing hormone agonist is usually combined with other therapies.Robust evidence is needed for the reproductive effect and safety of high intensity focused ultrasound ablation.

Radical versus conservative surgical treatment of liver hydatid cysts: a meta-analysis / 医学前沿

To date, the efficacy of radical surgery (RS) versus conservative surgery (CS) for liver hydatid cysts (LHC) remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients.

Introduction: Currently there is agreement regarding the importance of categorizing patients by risk groups in order to choose the most accurate treatment for well-differentiated thyroid cancer. Objective: To describe the results of conservative surgery as well as of total thyroidectomy performed on patients with well-differentiated thyroid cancer. Methods: A descriptive research of longitudinal cohort was performed between 1995 and 2016 at the General Surgery Service of Hermanos Ameijeiras Hospital. The main variables used were demographic, related with tumor, surgery type and type of results. Results: 183 patients were studied. The most used surgery type was the total thyroidectomy (79.2 percent). Individuals aged 41-50 years were predominant (30.6 percent). Conservative technics were more frequently performed in the group of patients aged 19-40. For patients older than 40 years, the total thyroidectomy was the most frequent. The female sex was the biggest group (82.5 percent). The predominant tumor size was in the range from 1 to 2.9 cm. In the low-risk group, 30 conservative surgeries and 62 total thyroidectomies were performed. Conservative surgeries had no complications, relapse or mortality. Regarding total thyroidectomy, 3.3 percent of the patients suffered transitory dysphonia, 2.2 percent presented transitory hypoparathyroidism, and 0.5 percent presented permanent hypoparathyroidism. Local relapse after total thyroidectomy was suffered by 3.8 percent of patients and mortality was 2.2 percent. Conclusions: The conservative surgery had no complications, relapse or mortality, while total thyroidectomy did present them(AU)

Introducción: el manejo y tratamiento del embarazo ectópico ha evolucionado en los últimos años de forma impresionante. Actualmente predomina una terapia conservadora, tanto médica como quirúrgica. Esta última, se manifiesta en función de la fertilidad a pesar del incremento de las afecciones tubárica. Objetivo: determinar el uso de la técnica de salpingostomía transversal con respecto al número de embarazos intrauterinos y recidivas posteriores. Métodos: se realizó un estudio experimental, prospectivo y longitudinal, en pacientes con diagnóstico de embarazo ectópico desde el año 2007 hasta el año 2012 en el Centro de Investigaciones Médico-Quirúrgicas. Esta población quedó conformada por 251 pacientes en edad fértil, que acudieron al Cuerpo de Guardia del Centro de Investigaciones Médico-Quirúrgicas por presentar dolor en bajo vientre, sangramiento uterino anormal y/o amenorrea, a quienes se les realizó laparoscopía diagnóstica. De ellas, 204 fueron diagnosticadas de embarazo ectópico, con 167 ampulares. La totalidad de las mujeres a las que se realizó la salpingostomía transversal mostraron interés en conservar la fertilidad. La muestra control quedó constituida por 200 pacientes que presentaron embarazo ectópico ampulares. Estas pacientes fueron sometidas a la técnica de cirugía conservadora longitudinal, en un periodo inmediato anterior, 2004-2007. Resultados: se demostró que por la técnica de salpingostomía transversal se logró un mayor número de embarazos intrauterinos (60) y menos recidivas de ectópicos (10), con valores altamente significativos respecto a la salpingostomía lineal. Conclusiones: el beneficio de realizar la técnica de salpingostomía transversal, respecto al número de embarazos logrados fue cuatro veces superior al riesgo de desarrollar recidivas o complicaciones en el período de un año(AU)

Introduction: The management and treatment of ectopic pregnancy has evolved dramatically in recent years. Presently, conservative therapy, both medical and surgical, prevails. The latter is manifested as a function of fertility despite the increase in tubal conditions. Objective: Determine the use of the transverse salpingostomy technique with respect to the number of intrauterine pregnancies and subsequent relapses. Methods: An experimental, longitudinal and prospective study was performed in patients diagnosed with ectopic pregnancy from 2007 to 2012 at Center for Medical-Surgical Research. 251 patients of childbearing age were the population of this study and they came to Center for Medical-Surgical Research emergency room for having low-grade pain, abnormal uterine bleeding and / or amenorrhea, who underwent diagnostic laparoscopy.This population consisted of 251 patients of childbearing age, who came to the Center for Medical-Surgical Research Guard Corps for having pain in the lower abdomen, abnormal uterine bleeding and / or amenorrhea. They underwent diagnostic laparoscopy. 204 of them were diagnosed of ectopic pregnancy, with 167 ampullaries. All women who underwent transverse salpingostomy showed interest in preserving fertility. 200 patients were the control sample ant they presented with ampullary ectopic pregnancy. These patients underwent longitudinal conservative surgery in an immediate previous period (2004-2007). Results: It was demonstrated that by the transverse salpingostomy technique, greater number of intrauterine pregnancies were achieved (60); fewer ectopic recurrences (10) with highly significant values ​​with respect to linear salpingostomy. Conclusions: The benefit of using transverse salpingostomy technique in relation to the number of pregnancies achieved was 4 times higher than the risk of developing relapses or complications in the period of one year(AU)

Patrones de reducción luego de quimioterapia neoadyuvante por cáncer de mama: implicancias en la cirugía conservadora / Reduction patterns after neoadjuvant chemotherapy for breast cancer. Implications for conservative surgery

Introducción: existen dos formas de respuesta tumoral a la quimioterapia neoadyuvante: concéntrica o dispersa. Los pacientes con respuesta dispersa no son buenos candidatos a cirugía conservadora porque sus microfocos tumorales pueden pasar desapercibidos en el tejido que rodea el tumor residual principal. Este tipo de respuesta se ha identificado como marcador de recurrencia ipsilateral luego de cirugía conservadora. Objetivo: el objetivo de este estudio es evaluar el porcentaje de respuesta de cada patrón y la suficiencia del margen obtenido en los casos de cirugía conservadora. Material y método: se analizaron los registros médicos de pacientes sometidos a cirugía luego de quimioterapia neoadyuvante entre mayo de 2004 y diciembre de 2013. Se efectuó un análisis detallado del tipo de quimioterapia recibida y de los informes patológicos para determinar el patrón de respuesta así como la de los fenotipos moleculares y el grado tumoral en cada caso. Resultados: 14 de los 55 casos (25%) presentaron un patrón de respuesta dispersa (diez con microfocos distantes de cáncer invasor y cuatro con microfocos distantes de cáncer in situ). El porcentaje de respuesta patológica completa fue de 15,4%. No hubo diferencias significativas en el tipo de respuesta entre los diferentes inmunofenotipos ni entre diferentes grados tumorales, ni entre las pacientes que recibieron taxanos y las que no los recibieron. Conclusiones: un cuarto de las pacientes de nuestra serie presentó un patrón de respuesta dispersa luego de quimioterapia neoadyuvante. Este es un signo de advertencia para aquellos que abogan por la cirugía conservadora luego de neoadyuvancia, ya que la respuesta difusa aumenta el riesgo de márgenes insuficientes y recurrencia ipsilateral.

Abstract Introduction: there are two patterns of tumor response to neoadjuvant chemotherapy: concentric or scattered. Patients with scattered response are not good candidates for conservative surgery since its tumor microfoci can go unnoticed in the tissue around the main residual tumor. The kind of response has been identified as an ipsilateral recurrence factor after conservative surgery. Objective: the study aims to evaluate the response percentage for each pattern and sufficiency of the surgical resection margin obtained in the cases of conservative surgery. Method: the medical records of patients who underwent surgery after neoadjuvant chemotherapy between May 2004 and December 2013 were analysed. The type of chemotherapy and the histopathology reports were thoroughly analysed to determine the reponse pattern, as well as the molecular phenotypes and the degree of tumor for each case. Results: 14 out of 55 cases (25%) presented a scattered response pattern (ten of them with distant microfoci from the invasive cancer and four with distant microfoci of in situ cancer). Percentage of pathologic complete response was 15.4%. There were no significant differences in the response patterns among the different immunophenotypes or among different degrees of tumors, and neither was there a significant difference between those who received taxenes and those who did not receive it. Conclusions: one fourth of patients in our series presented a scattered reponse pattern after neoadjuvant chemotherapy. This may be a warning signal for those who advocate for conservative surgery after neoadjuvant treatment, since scattered response increases the risk of insufficient margins and ipsilateral recurrence.

Resumo Introdução: existem duas formas de resposta tumoral à quimioterapia neoadjuvante: concêntrica ou dispersa. Os pacientes com resposta dispersa não são bons candidatos à cirurgia conservadora porque seus microfocos tumorais podem passar despercebidos no tecido que rodea o tumor residual principal. Este tipo de resposta foi identificado como marcador de recorrência ipsilateral pós-cirurgia conservadora. Objetivo: avaliar a porcentagem de resposta de cada padrão e a suficiência da margem obtida nos casos de cirurgia conservadora. Material e método: os prontuários médicos dos pacientes submetidos à cirurgia pós-quimioterapia neoadjuvante no período maio de 2004 - dezembro de 2013 foram analisados. Foi realizada uma análise detalhada do tipo de quimioterapia recebida e dos laudos patológicos para determinar o padrão de resposta bem como dos fenótipos moleculares e do grau tumoral em cada caso. Resultados: 14 dos 55 casos (25%) apresentaram um padrão de resposta dispersa (dez com microfocos distantes de câncer invasor e quatro com microfocos distantes de câncer in situ). A porcentagem de resposta patológica completa foi de 15,4%. Não foram encontradas diferenças significativas no tipo de resposta entre os diferentes imunofenótipos nem entre os diferentes graus tumorais, nem entre os pacientes que receberam taxanos e os que não os receberam. Conclusões: um quarto dos pacientes da nossa serie apresentou um padrão de resposta dispersa pós-quimioterapia neoadjuvante. Este é um sinal de advertência para os que defendem a cirurgia conservadora pós neoadjuvancia, considerando que a resposta difusa aumenta o risco de margens insuficientes e recorrência ipsilateral.
