Laparoscopic appendicectomy without the use of disposable materials - a low-cost alternative - 1, 552 cases operated in 20 years / Apendicectomia laparoscópica sem uso de materiais descartáveis - uma alternativa de baixo custo - 1. 552 casos operados em 20 anos

ABSTRACT Introduction: Laparoscopic appendectomy does not have a single protocol on its technical systematization, access routes, and use of energy and staplers. The cost of disposable materials can prevent its widespread use. Alternatives to decrease cost can help disseminate the laparoscopic access to appendectomy. Objective: to introduce a low-cost laparoscopic appendectomy method with good aesthetic results through the location of incisions; to show its viability through its application in 1,552 cases of laparoscopic appendectomy operated between 2000 and 2019 with three portals and very low-cost regarding materials used. Methods: we applied three punctures - an umbilical one for the camera (5 or 10mm in diameter), a 10mm puncture in the right iliac fossa, and one 5mm puncture in the left iliac fossa. The materials used were permanent use trocars, grasping forceps, hook, scissors, and needle holder, without the need for any disposable device. Results: 1.552 patients were operated between 2000 and 2019, 56.2% being female, mean age 32.66 years (9-93), average hospital stay of 1.74 days (1-10), and median of 1.2 days. Conclusion: the technique we describe uses three metallic trocars and four permanent instruments, in addition to a single cotton suture. It is, therefore, a very low-cost laparoscopic procedure. Its application has shown good results and low morbidity, which may become the preferred indication for laparoscopic surgery in the treatment of acute appendicitis.

RESUMO Introdução: a apendicectomia videolaparoscópica não tem protocolo único sobre sistematização técnica, vias de acesso, uso de energia e grampeadores. O custo de materiais descartáveis pode inviabilizar o emprego mais generalizado. Alternativas para diminuir o custo podem ajudar a disseminar o acesso laparoscópico para a realização de apendicectomia. Objetivo: introduzir um método para realizar a apendicectomia videolaparoscópica de baixo custo e visando bom resultado estético por meio da localização das incisões; mostrar a viabilidade por meio de aplicação em 1.552 casos de apendicectomia videolaparoscópica operados entre 2000 e 2019 com três portais, de muito baixo custo em insumos utilizados. Métodos: três punções - uma punção umbilical para introdução da câmera (de 5 ou 10mm de diâmetro), uma punção de 10mm em fossa ilíaca direita e uma punção em fossa ilíaca esquerda de 5mm. Os materiais utilizados - trocartes, pinças de apreensão, gancho, tesoura e porta-agulhas são de uso permanente, sem necessidade de qualquer material descartável. Resultados: foram operados 1.552 pacientes entre 2000 e 2019, sendo 56,25% do sexo feminino, média de idade de 32,66 anos (9 a 93 anos), tempo médio de internação de 1,74 dias (1 a 10 dias) e mediana de 1,2 dias. Conclusão: a técnica que descrevemos utiliza três trocartes metálicos e quatro instrumentos permanentes, além de um único fio de algodão. Trata-se, portanto, de procedimento laparoscópico de muito baixo custo. A aplicação demonstrou bons resultados e baixa morbidade, podendo tornar-se rotina a indicação preferencial da vídeocirurgia no tratamento da apendicite aguda.

Endometriosis cutánea primaria umbilical: a propósito de un caso / Umbilical Primary Cutaneous Endometriosis: A Case Report / Endometriose cutânea primária umbilical: relato de caso

Introducción: la endometriosis es una de las patologías ginecológicas más frecuentes, que se entiende como la implantación intrapélvica de tejido endometrial, sensible, en la gran mayoría de casos, al influjo hormonal. Extrauterinamente, se caracteriza por la presencia de glándulas y estroma endometrial en órganos o tejidos no ginecológicos. Sin embargo, la piel corresponde a uno de los sitios con menor fre-cuencia de implantación, ya sea de forma primaria o secundaria. Se calcula la incidencia de endometrio-sis cutánea en la zona umbilical en menos del 1 % de los casos. Presentación del caso: mujer de 36 años de edad, quien consulta con Cirugía General por un cuadro clínico de dos años de evolución, consistente en lesiones sobrelevantadas de la piel en la región umbilical, de color café oscuro, las cuales describe como dolorosas y sangrantes en el momento del ciclo menstrual. A pesar de haber sido resecadas en dos ocasiones, se encontró persistencia del cuadro. Discusión: la endometriosis cutánea primaria umbilical representa del 0.5 al 1.0 % de todas las pacientes con endometriosis ectópica, y el ombligo es uno de los sitios menos comunes de implantación. Esta condición afecta alrededor del 5 al 15 % de mujeres en edad fértil, y del 3 al 5 % de mujeres en edad menopaúsica. La presentación clínica más común se basa en una masa palpable, sangrado umbilical y dolor regular o irregular abdominal. Al asociar la endometriosis extrapélvica con la presencia de endometriosis pélvica, solamente alrededor del 20 % de las pacientes presentará esta última

Introduction: Endometriosis is one of the most frequent gynecological pathologies, understood as an intrapelvic implantation of endometrial tissue, sensitive to hormonal influence in most cases. At the extrauterine level, it is characterized by the presence of endometrial glands and stroma in the non-gy-necological organs or tissues. However, the skin corresponds to one of the sites with the least frequency of implantation, either primary or secondary, with the incidence of cutaneous endometriosis being calculated at the umbilical level in <1% of the cases. Case presentation: A 36-year-old female patient presented to the General Surgery department with a two-year history of dark brown, raised skin lesions in the umbilical region, which she described as painful, and bleeding at the time of the menstrual cycle. Despite having been resected twice, the condition still persisted. Discussion: Umbilical primary cutane-ous endometriosis represents 0.5%­1.0% of all patients with ectopic endometriosis, with the navel being one of the least common implantation sites. This condition affects about 5%−15% of women of childbear-ing age, and 3%−5% women of menopausal age. The most common clinical presentation is based on the palpable mass, umbilical bleeding, regular or irregular abdominal pain. Associating extrapelvic endo-metriosis with the presence of pelvic endometriosis, only about 20% of the patients will have the latter

Introdução: a endometriose é uma das patologias ginecológicas mais frequentes, entendida como o implante intrapélvico de tecido endometrial, sensível na grande maioria dos casos à influência hor-monal. No nível extrauterino, é caracterizada pela presença de glândulas e estroma endometriais em órgãos ou tecidos não ginecológicos. Porém, a pele corresponde a um dos locais com menor frequência de implantação, seja ela primária ou secundária, calculando-se a incidência de endometriose cutânea ao nível umbilical em menos de 1% dos casos. Apresentação do caso: paciente do sexo feminino, com 36 anos de idade, que consulta para Cirurgia Geral devido a quadro clínico de 2 anos de evolução, cons-tituído por lesões cutâneas elevadas na região umbilical, de coloração marrom-escura, que descreve como dolorosas e com sangramento no momento do ciclo menstrual. Apesar de ter sido ressecado em 2 ocasiões, o quadro era persistente. Discussão: a endometriose cutânea primária umbilical representa 0.5%-1.0% de todas as pacientes com endometriose ectópica, sendo o umbigo um dos locais de implan-tação menos comuns. Essa condição afeta cerca de 5% a 15% das mulheres em idade reprodutiva e 3% a 5% das mulheres em menopausa. A apresentação clínica mais comum baseia-se em massa palpável, sangramento umbilical, dor abdominal regular ou irregular. Ao associar a endometriose extrapélvica à presença de endometriose pélvica, apenas cerca de 20% das pacientes a apresentarão

Brief analysis on GAO Shu-zhong's qiguan theory and its clinical application / 中国针灸

The paper introduces professor GAO Shu-zhong's experience in qiguan (umbilicus pass) theory and its clinical application. Professor GAO believes that the umbilicus is the "pass" where the primary qi of sanjiao transported from the lower jiao to the middle jiao. It is the general pivot of qi transformation of yin and yang, as well as the place for qi ascending, descending, exiting and entering in the human body. Hence, the umbilicus is called qiguan (umbilicus pass). In clinical practice, associated with observation, palpation and pulse diagnosis, the qiguan theory is conductive to disease diagnosis. Moreover, the therapeutic methods for promoting qiguan is generated, i.e. umbilicus-acupuncture therapy and umbilicus-moxibustion therapy. In the umbilicus-acupuncture therapy, Gao 's umbilicus five points (umbilicus heart, umbilicus stomach, umbilicus liver, umbilicus kidney and umbilicus lung) are commonly selected. With the umbilicus- moxibustion therapy, the isolated moxibustion with different herbal materials is exerted at the umbilicus, in which, the herbal materials with drastic medical action, pungent and fragrant in flavor and warm in property are specially selected.

Bone proportional measurement on the chest and abdomen among 101 young females / 中国针灸

OBJECTIVE@#To examine the bone proportional measurement standard on the chest and abdomen of modern women.@*METHODS@#The height, weight and distances of bone proportional measurement chest and abdomen of 101 young females were measured. The height was divided by 75 to calculate the data of bone proportional measurement, and compared with the national standard published in 2006 and the ancient literature of Miraculous Pivot: Gudu.@*RESULTS@#The bone proportional distances between two nipples and two coracoid processes of women were 8 cun and 12 cun respectively, which were in line with the 2006 national standard. The bone proportional distance from navel to superior margin of pubic symphysis (Qugu) was 6.5 cun, which was consistent with the ancient literature of Miraculous Pivot: Gudu. The bone proportional distance from suprasternal fossa to the middle point of xiphisternal synchondrosis (Qigu) was less than 9 cun, while the bone proportional distance from Qigu to navel was more than 8 cun, resulting in the ratio less than 9︰8. The bone proportional distance from suprasternal fossa to the middle point of xiphoid process was 9 cun, corresponding to the ratio of 9︰8 when comparing with the measurement from the middle point of xiphoid process to navel.@*CONCLUSION@#The bone proportional distance measurement between two nipples and two coracoid processes of women should follow the 2006 national standard, and the bone proportional distance measurement from navel to superior margin of pubic symphysis should follow the standard of Miraculous Pivot: Gudu. The middle point of xiphisternal synchondrosis should be replaced by the middle point of xiphoid process.

Professor YANG Ji-guo's experience in treatment of functional gastrointestinal diseases with acupuncture combined with umbilicus moxibustion / 中国针灸

Professor YANG Ji-guo's clinical experience in treatment of functional gastrointestinal diseases was summerized. Professor YANG Ji-guo believes that this disease is caused by the deficiency of six fu organs. Dysfunction of six fu organs in descending transportation is the basic pathogenesis. The principle of acupoint selection includes benefiting gastrointestinal functions, unblocking and purging six fu, soothing liver qi and calming down the mind. In treatment, acupuncture is combined with umbilicus moxibustion. In acupuncture, the deqi promoting technique by rotating and trembling needle is adopted. Focusing on the deficiency of six fu organs, umbilicus moxibustion is adopted to benefit the spleen and stomach and harmonize the functions of six fu organs for both biao (symptoms) and ben (root cause).

Risk factors related to the appearance of umbilical disorders in dairy calves / [Fatores de risco relacionados ao surgimento de afecções umbilicais em bezerros leiteiros]

The objective of this study was to determine the types of calve housing used in dairy farms, the prevalence of umbilical disorders and related risk factors. The 16 farms studied were visited to characterize the types of installation and possible risk factors, as well as information obtained from a questionnaire applied to the farmers. 806 Holstein calves were physically examined, in addition to collecting blood samples for the evaluation of Failures in Passive Immunity Transfer (FPIT), in animals that manifested inflammatory omphalopathies, and were also submitted to ultrasound examination. The prevalence of omphalopathies was assessed by Fisher's test, and multivariate logistic regression to assess risk factors. Eight types of installation were found: tropical house, suspended cage, collective stall, collective picket, Argentinean type, single-story cage, individual stall, and collective picket with chain. Omphalopathies accounted for 6.45% of the calves. Small size farms (up to 99 lactation cows) had high risk for umbilical disorders, ground floor collective calves, without side protection, with sand floor, in closed sheds and without heatstroke were considered risk factors for omphalopathies. Adequate colostrum and umbilical antisepsis are not associated with disease, its appearance being related to the housing conditions of the animals.(AU)

O objetivo deste estudo foi determinar os tipos de alojamento para bezerros leiteiros, a prevalência de onfalopatias e os fatores de risco relacionados. As 16 fazendas estudadas foram visitadas buscando-se caracterizar os tipos de instalação e os possíveis fatores de risco, além de informações obtidas de um questionário aplicado aos fazendeiros. Foram examinados fisicamente 806 bezerros da raça Holandesa, além da coleta de amostras de sangue, para avaliação da falha de transferência de imunidade passiva (FTIP), nos animais que manifestaram onfalopatias inflamatórias, sendo submetidos também ao exame ultrassonográfico. A prevalência das onfalopatias foi avaliada por teste de Fisher, e foi feita regressão logística multivariada a fim de se avaliarem os fatores de risco. Verificou-se oito tipos de instalação: casinha tropical, gaiola suspensa, baia coletiva, piquete coletivo, bezerreiro tipo argentino, gaiola térrea, baia individual e piquete coletivo com corrente. As onfalopatias corresponderam a 6,45% dos bezerros. Os bezerreiros coletivos térreos, sem proteções laterais, com piso de areia, borracha, concreto ou madeira, em galpões fechados, sem insolação, com alta densidade animal, antissepsia umbilical realizada por três dias e FTIP acima de 50% foram considerados fatores de risco para onfalopatias e possuem relação com o bezerreiro, sendo decisivas para evitar essas condições a colostragem e a antissepsia umbilical adequadas.(AU)

Endometriosis umbilical primaria: reporte de dos casos / Primary umbilical endometriosis: two case reports

INTRODUCCIÓN: La endometriosis es una patología benigna, dependiente de estrógenos, en la que el tejido que normalmente crece dentro del útero aparece fuera de este. Su localización habitual es en la pelvis, pero en ocasiones puede aparecer en otras áreas, como es el caso de la endometriosis umbilical. OBJETIVO: Familiarizar al ginecólogo con esta patología y entregar una serie de herramientas para diagnosticar, tratar y seguir a las pacientes que la presentan. CASOS CLÍNICOS: Se presentan dos casos clínicos de endometriosis umbilical primaria diagnosticados en el Hospital La Paz, en Madrid (España), entre los años 2018 y 2019. Las pacientes, de 30 y 34 años, consultaron por dolor o sangrado umbilical durante la menstruación. Ninguna tenía antecedentes de patología ginecológica ni cirugía abdominal previa. Tras una exhaustiva exploración física y una ecografía de alta resolución, se decidió extirpar la lesión con la colaboración del servicio de cirugía plástica. En ambos casos, el estudio anatomopatológico confirmó que se trataba de tejido endometriósico. Las dos pacientes presentaron una buena evolución posquirúrgica, sin recidivas hasta la fecha. CONCLUSIONES: La endometriosis umbilical primaria es una patología infrecuente, pero es necesario incluirla en el diagnóstico diferencial de una mujer con un nódulo umbilical. Siempre deben realizarse una exploración física exhaustiva y una ecografía ginecológica, para descartar posibles patologías concomitantes. El tratamiento de elección es la extirpación quirúrgica de la lesión y el diagnóstico final se establece con el estudio anatomopatológico.

INTRODUCTION: Endometriosis is an estrogen-dependent benign pathology in which endometrial tissue develops outside the uterus. Its most frequent location is the pelvis, although it can appear in other areas such as the umbilicum. OBJECTIVE: To familiarize the gynecologist with this pathology and provide a series of tools to diagnose, treat and provide continued care to these patients. CASE REPORTS: Retrospective study of two clinical cases of primary umbilical endometriosis diagnosed at La Paz University Hospital, in Madrid (Spain), between 2018 and 2019. Both patients (30 and 34 years old respectively) presented with pain and/or bleeding around the umbilical area during menstruation. Neither of them had any previous gynecologic conditions or abdominal surgeries. After exhaustive physical examination and a high-resolution ultrasound, lesions were surgically removed in collaboration with the plastic surgery department. In both cases, histology confirmed the presence of endometrial tissue. Both patients made a full recovery after surgery and havent had a recurrence of said lesions. CONCLUSIONS: Primary umbilical endometriosis is an infrequent disease. However, it must be included in the differential diagnosis of umbilical nodes in women. Exhaustive physical examination and gynecologic ultrasound should always be performed to rule out any other pathologies. Surgical removal of the nodes is the preferred treatment, and the final diagnosis is reached through histology.

Quiste pilonidal del ombligo: presentación de dos casos / Umbilical pilonidal sinus: presentation of two cases

Resumen Introducción: El quiste pilonidal del ombligo (QPO) es una entidad muy infrecuente y por eso no es reconocida precozmente. El objetivo de este manuscrito es dar a conocer esta patología. Reporte de casos: Presentamos dos pacientes referidos por un proceso inflamatorio del ombligo, con descarga de mal olor. El primer paciente, luego de dos meses de tratamiento local sin resolución, es intervenido resecando la lesión umbilical, comprobando en ese momento la existencia de contenido piloso en el quiste. En el segundo paciente se plantea el diagnóstico durante la anamnesis y se confirma con el examen físico. En ambos casos se efectuó una resección parcial del ombligo incluyendo la lesión pilonidal. La biopsia confirmó el diagnóstico. El resultado posoperatorio ha sido satisfactorio y sin recaídas. Discusión y Conclusión: Hay escasa literatura relacionada con el QPO. Se proponen el tratamiento conservador y la opción de resección quirúrgica del quiste. En nuestra limitada experiencia se procedió a resecar la lesión y recomendar la depilación de la región periumbilical. No podemos descartar la alternativa de manejo conservador en futuros casos, antes de proponer la cirugía.

Introduction: Umbilical pilonidal sinus (UPS) is a rare condition and is therefore not detected early. The aim of this document is to discuss this pathology. Case report: We present two patients referred due to an inflammatory process of the navel, with the presence of a malodor. The first patient, after two months of unsuccessful local treatment, was intervened by a resection of the umbilical lesion, verifying hair content in the sinus. In the second patient the diagnosis was evident during anamnesis and confirmed with the physical examination. In both cases, a partial resection of the umbilicus was performed, including the pilonidal sinus. Biopsy confirmed the diagnosis. The postoperative result has been satisfactory, without relapse. Discussion and Conclusion: There are not much literature related to UPS. Conservative treatment or surgical resection of the sinus is proposed. In our limited experience we proceeded to a surgical resection of the lesion and recommend eliminating the hairs of the periumbilical region. We cannot rule out the conservative management option in future cases, before proposing surgery.

Abordagem cirúrgica em bezerros com onfalite / Surgical approach in calves with omphalitis

Pathological changes in the umbilical region are common in calves. Among such alterations, omphalitis is included. This term is used to define inflammation and infection of the external structures of the umbilicus. According to the affected structures, it can be subclassified into omphalophlebitis, omphaloarteritis, omphalourachitis and panvasculitis. These inflammations are usually associated with bacterial infections. There are predisposing conditions that include inadequate handling such as poor hygiene and neglect of primary care. Omphalitis can affect the animal in a multisystemic way, compromising its well-being and bringing economic losses. In treatment, the use of antimicrobials does not always solve the problem. Thus, surgical treatment can be used, which has good results and should be the choice in the disease. The objective of this work is to report 30 cases of omphalitis in calves, submitted to surgical or conservative treatment. Thirty cases of omphalitis in calves treated in the routine of the Veterinary Hospital of the Paranaense University was analyzed. On physical examination, the animals presented fever, apathy, hyporexia or anorexia and increase of umbilical volume, usually with purulent secretion. Some animals had sepsis and arthritis. In animals with sepsis, hyperemia of the episcleral vessels, dehydration and severe apathy were observed. In calves with arthritis, increased joint volume, pain on palpation and lameness were observed. In animals where the owners did not authorize the surgery, treatment was instituted with sulfadoxine and flunixim meglumine. In dehydrated calves, fluid therapy was used. Animals that were surgically treated received the same clinical treatment protocol as non-operated animals. The surgical procedure was performed under general anesthesia and consisted of resection of the affected umbilical structures. Omphalophlebitis was the most common illness. The most frequent complication was sepsis. Calves treated surgically had a higher survival rate (86.66%) than those treated clinically (46.67%). The clinical signs presented by all animals converged with the literature, allowing for clinical diagnosis. Clinical examination is essential for diagnosis in omphalitis cases. Complementary methods include ultrasound, thermography and laparoscopy, which are important to identify changes in intra-abdominal umbilical structures. Accurate diagnosis of the involved structures was only possible in animals surgically, as well as alterations in organs such as the liver and bladder. There is great variability related to the umbilical structures involved, according to initial care, breeds, seasonality or even the method of conception. Unlike what is observed in the literature, in the present study, there was a higher prevalence of omphalophlebitis, demonstrating variability in relation to the umbilical structures involved. Sepsis, observed in 16.7% of cases, results from bacterial ascension of the umbilical structures. Lameness due to polyarthritis was found in 10% of animals. Meningoencephalitis was observed in 3.3%. Hepatic and retroperitoneal abscedation were observed in 6.7% and 3.3% of cases, respectively. Conservative treatment with antibiotics and local antiseptics has a limited effect on this type of condition, which was proven in the present study, since the survival rate was statistically higher in animals surgically treated.(AU)

Persistencia simultánea del conducto uraco y onfalomesentérico en un paciente adulto, reporte de caso / Simultaneous persistence of the urachus and vitelline ducts in an adult patient, case report / Persistência simultânea de úraco e do ducto onfalomesentérico em um paciente adulto: relato de caso

Introducción. La patología umbilical es un tema frecuente en el ámbito pediátrico, la presentación clínica de una fístula umbilical hace pensar en dos patologías mencionadas en la literatura de manera independiente; la primera es la persistencia del conducto onfalomesentérico y la segunda es la persistencia del remanente del uraco producto del fracaso en el cierre de las estructuras embrionarias. Su presencia en adultos es infrecuente y no existen datos estadísticos acerca de su presentación conjunta en población pediátrica o adulta, solo algunos pocos reportes de caso. El diagnóstico se basa principalmente en la sospecha clínica, depende en gran manera del examen físico al evidenciar secreción a través del ombligo al realizar esfuerzos o maniobras de Valsalva. Objetivo. Mostrar un caso infrecuente de la presentación simultánea del conducto de uraco y onfalomesentérico en un paciente adulto. Reporte de caso. Paciente femenina de 24 años de edad con antecedentes de infecciones urinarias y celulitis periumbilicales a repetición. Se sospecha un conducto persistente onfalomesentérico por lo que es sometida a un procedimiento quirúrgico en el que se encontró incidentalmente la persistencia simultánea del conducto onfalomesentérico y persistencia del uraco. Discusión. La persistencia del conducto onfalomesentérico o la persistencia del uraco de forma individual es poco frecuente en adultos, y es aún más raro la persistencia simultánea de ambos conductos; la presencia simultánea de ambos conductos es reportada principalmente en menores de dos años. Conclusiones. La persistencia de estos conductos es rara en adultos y representa un reto diagnóstico para el clínico.

Introduction. Umbilical pathology is a common topic in the pediatric sphere. The clinical presentation of an umbilical fistula leads to the consideration of two pathologies independently reported in literature. The first is a persistent vitelline duct and the second is a persistent urachal remnant as a result of the embryonic structures' failure to close. They are uncommon in adults and there are no statistical data about their presentation together in the pediatric or adult population, only very few case reports. The diagnosis is mainly based on clinical suspicion. It largely depends on a physical examination noting secretion through the navel when straining or performing Valsalva maneuvers. Objective. Show an uncommon case of the simultaneous presentation of the urachus and vitelline ducts in an adult patient. Case report. Female patient aged 24 years with a background of repeated urinary tract infections and periumbilical cellulitis. A persistent vitelline duct is suspected. Therefore, the patient is subject to a surgical procedure in which the simultaneous persistence of the vitelline duct and the urachus was found incidentally. Discussion. The persistence of the vitelline duct or the persistence of the urachus individually is uncommon in adults, and the simultaneous persistence of both ducts is even rarer. The simultaneous presence of both ducts is reported mainly in infants aged under two years. Conclusions. The persistence of these ducts is rare in adults and poses a diagnostic challenge for clinicians.

Introdução. A patologia umbilical é um tópico frequente no cenário pediátrico; a apresentação clínica de uma fístula umbilical faz pensar em duas patologias mencionadas na literatura de forma independente; a primeira é a persistência do ducto onfalomesentérico e a segunda é a persistência do úraco como resultado da falha no fechamento das estruturas embrionárias. É pouco frequente sua presença em adultos e não há dados estatísticos sobre sua apresentação conjunta em população pediátrica nem adulta, apenas alguns poucos relatos de caso. O diagnóstico baseia-se principalmente na suspeita clínica, dependendo em grande parte do exame físico ao evidenciar uma secreção pelo umbigo quando realizar esforço ou manobra de Valsalva. Objetivo. Mostrar um caso infrequente de apresentação simultânea do úraco e ducto onfalomesentérico em um paciente adulto. Relato de caso. Paciente do sexo feminino, 24 anos, com histórico de infecções urinárias e celulite periumbilical recorrentes. Suspeita-se de um ducto onfalomesentérico persistente, portanto ela é submetida a um procedimento cirúrgico no qual encontrou-se a persistência do ducto onfalomesentérico e a persistência de úraco simultaneamente. Discussão. A persistência do ducto onfalomesentérico e a persistência de úraco individualmente é rara em adultos, e a persistência simultânea de ambos os ductos é ainda mais rara; esta presença simultânea é relatada principalmente em crianças menores de dois anos de idade. Conclusão. A persistência desses ductos é rara em adultos e representa um desafio diagnóstico para o profissional de saúde clínico.

The anti-clockwise spiralization of the linea nigra sign / O sinal do espiralamento anti-horário da linea nigra

ABSTRACT Objective: To describe the morphology of the supra- and infraumbilical linea nigra in puerperal women. Methods: The study was conducted from September 2017 to April 2018, and included 157 puerperal women admitted for childbirth care at the Obstetrics Department of a public maternity hospital of the city of São Paulo (SP), Brazil. The abdomen of subjects was photographed on the first or second day postpartum, with the patient lying symmetrically in dorsal decubitus at a standardized distance. Contrast was slightly adjusted and the morphological pattern of supra and infraumbilical linea nigra in the proximity of the umbilical scar was characterized. The images were independently analyzed by two researchers and only the matching results from both observers were used. Results: Of the 157 observed cases, 139 (88.5%) images provided concordant results between the two researchers. Excluding 41 cases of absence or poor definition of the linea nigra, 98 images were analyzed. Supra- and infraumbilical linea nigra were analyzed separately and classified according to three directions (left, center and right of the umbilical scar). The combination of the supra- and infraumbilical images resulted in the formation of nine distinct patterns, being the most prevalent, in primiparous (72.2%) and multiparous women (50.0%), and the authors named as "anticlockwise spiralization of the linea nigra". Conclusion: The analysis of supra- and infraumbilical linea nigra in puerperal women showed a predominance of what the authors named "anti-clockwise spiralization of the linea nigra sign".

RESUMO Objetivo: Descrever a morfologia da linea nigra supra e infraumbilical em puérperas. Métodos: O estudo foi realizado no período de setembro de 2017 a abril de 2018 e incluiu 157 puérperas admitidas para o parto no Serviço de Obstetrícia de uma maternidade pública da cidade de São Paulo (SP). O abdome das pacientes foi fotografado no primeiro ou segundo dia pós-parto, com a paciente deitada simetricamente em decúbito dorsal a uma distância padronizada. O contraste foi ligeiramente ajustado, e o padrão morfológico da linea nigra supra e infraumbilical na proximidade da cicatriz umbilical foi caracterizado. As imagens foram analisadas independentemente por dois pesquisadores, e apenas os resultados concordantes dos dois observadores foram utilizados. Resultados: Dos 157 casos observados, 139 (88,5%) imagens apresentaram resultados concordantes entre os dois pesquisadores. Excluindo 41 casos de ausência ou má definição da linea nigra, 98 imagens foram analisadas. As linea nigra supra e infraumbilicais foram analisadas separadamente e classificadas de acordo com três direções (esquerda, centro e direita da cicatriz umbilical). A combinação das imagens supra e infraumbilicais resultou na formação de nove padrões distintos, sendo os mais prevalentes nas primíparas (72,2%) e multíparas (50,0%), o que os autores denominaram "espiralamento anti-horário da linea nigra". Conclusão: A análise das linea nigra supra e infraumbilical em puérperas mostrou predominância do que os autores denominaram "sinal do espiralamento anti-horário da linea nigra".

Onfaloplastia em triângulo isósceles e com dupla fixação na abdominoplastia / Omphaloplasty based on an isosceles triangle with double fixation in abdominoplasty

Introdução: Na abdominoplastia convencional, a cicatriz do novo umbigo representa o ponto de maior desafio. Em sua execução, já foram descritas e utilizadas várias técnicas e táticas cirúrgicas, com resultados nem sempre satisfatórios, sob o ponto de vista do paciente e também do médico. O objetivo é demonstrar a aplicabilidade e satisfação com a onfaloplastia em triângulo isósceles e com dupla fixação na abdominoplastia. Métodos: Foram selecionadas 97 pacientes do sexo feminino, com idades entre 25 e 65 anos. Todas foram submetidas à dermolipectomia abdominal clássica associada à lipoaspiração moderada de todo abdome anterior e flancos e avaliadas com 90, 180 e 360 dias pós-operatórios, pelo mesmo cirurgião. Resultados: Observou-se um índice de resultados satisfatórios das cicatrizes umbilicais na maioria dos casos (92,8%). Algumas cicatrizes umbilicais apresentaram estenoses (3,1%) e outras, cicatrizes inestéticas (4,1%). Não se observaram necroses. Conclusão: A utilização desta técnica demonstrou ser eficaz, de fácil execução e com resultados muito satisfatórios na estética da cicatriz umbilical nas dermolipectomias abdominais.

Introduction: In conventional abdominoplasty, the creation of a new umbilical scar is challenging. Several surgical techniques and approaches have previously been described and applied, but not always with satisfactory results. The objective is to demonstrate the applicability and satisfaction with omphaloplasty based on an isosceles triangle with double fixation in abdominoplasty. Methods: The study included 97 female patients aged between 25 and 65 years. All underwent classic abdominal dermolipectomy with moderate abdominal liposuction of the entire anterior abdomen and flanks by the same surgeon and were evaluated at 90, 180, and 360 days postoperatively. Results: Patients were satisfied with the umbilicus in most cases (92.8%). Some umbilical scars had contracted (3.1%) and others appeared unsightly (4.1%). No necrosis was observed. Conclusion: This technique was effective and easy to perform, with satisfactory umbilical scar aesthetic outcomes in abdominal dermolipectomy.

Endometriosis de la pared abdominal: estudio descriptivo de una serie de 21 casos / Abdominal wall endometriosis: A descriptive study of a series of 21 cases

Introducción. La endometriosis de la pared abdominal se define como la presencia de tejido endometrial en cualquiera de las capas que componen la pared abdominal. Su incidencia es baja y se caracteriza por un diagnóstico tardío. Materiales y métodos. Se trata de un estudio descriptivo y retrospectivo entre 2010 y 2014 en pacientes con endometriosis de la pared abdominal, cuyo análisis patológico fue realizado en un centro de ayudas diagnósticas de Medellín. Se identificaron las variables histopatológicas del reporte, y la información clínica mediante una entrevista telefónica suministrada por la paciente. Se analizaron los datos con medidas descriptivas de resumen. Resultados. Participaron 21 de 65 pacientes con diagnóstico de endometriosis de la pared abdominal. La media de edad al momento del diagnóstico fue de 35,3 años (desviación estándar, DE=8), el 71,4 % tenía el antecedente de cesárea y, el 38,1 %, el de endometriosis pélvica. El 95,2 % de las pacientes manifestaron dolor, de las cuales el 50 % lo percibió como constante con agudización cíclica y, el 40 %, como cíclico; además, el 90,5 % manifestó sensación de masa. La mediana del tiempo desde la aparición de la lesión hasta el diagnóstico, fue de 24 meses (RIQ=6-60). Solo en cuatro pacientes se hizo el diagnóstico prequirúrgico. El tratamiento fue quirúrgico en todas las pacientes y ocho (38,1 %) presentaron recidiva.Conclusiones. La endometriosis de la pared abdominal usualmente se manifiesta como masas dolorosas aso-ciadas con cicatrices quirúrgicas previas, generalmente de origen ginecológico y los síntomas empeoran con la menstruación. Es usual que su diagnóstico sea tardío y pocas veces se hace antes del estudio histopatológico. El tratamiento de elección es la resección quirúrgica, aunque no es despreciable el porcentaje de recidivas (AU)

Introduction: Abdominal wall endometriosis is defined by the presence of endometrial tissue in any of the layers that compose the abdominal wall. It has a low incidence and is characterized by a late diagnosis. Materials and Methods: A descriptive, ambispective study that included patients with abdominal wall endometriosis whose pathological analysis was performed in a diagnostic center in Medellín between 2010 and 2014. Histopathological variables of the report were identified, and clinical information was provided by the patient by a phone interview. They were analyzed with descriptive summary measures.Results: 21 patients with abdominal wall endometriosis of 65 identified participated. The mean age at diagnosis was 35.3 years ± 8, 71.4% had a prior caesarean section and 38.1% had pelvic endometriosis. 95.2% manifested pain, among them, 50% was perceived as constant with cyclical exacerbation, 40% cyclical; 90.5% manifested mass sensation. The median from the onset of the lesion to the diagnosis was 24 months (IQR 6-60). Only four patients had pre-surgical. The treatment was surgical in all patients and eight (38.1%) had recurrence.Conclusions: Abdominal wall endometriosis usually manifests through painful masses associated with previous surgical scars usually of gynecological origin and whose symptoms worsen with menstruation. Its diagnosis is usually late and it is rarely reached before the histopathological study. Management of choice is surgical resection, however, its percentage of recurrence is not negligible (AU)

A modified open primary laparoscopic surgery port placement through umbilical tube

Background:A safe, reliable technique for primary trocar introduction is important for laparoscopic surgery. In resource-constrained settings where there is paucity of needed equipment and cost is prohibitive, a method utilizing fewer instruments will be useful.Aim:This study aims to describe a method of primary trocar introduction that utilizes any available port.Methods:A supra- or infra-umbilical incision is made into an everted tubular umbilicus. The linear alba is incised and the resultant opening bluntly developed, after which any available port is inserted using the trocar as a guide. The trocar is withdrawn while the sleeve is pushed in.Results:One hundred and three successful insertions were affected in 107 patients with age range of 1­75 years, with no significant gas leaks.Conclusion:This modified open approach is a simple and reliable way of primary port insertion. Access is gained easily in different age groups and umbilicus types

Single-Incision, Two-Port Laparoscopic Appendectomy as an Alternative to Transumbilical Single-Port Laparoscopic Appendectomy

PURPOSE: We designed a modified technique to perform an advanced procedure using conventional instruments and did not employ specialized single-incision laparoscopic surgery (SILS) port equipment. We compared postoperative results for transumbilical, single-port laparoscopic appendectomy (TUSPLA) and single-incision, 2-port laparoscopic appendectomy (SITPLA). METHODS: This retrospective study enrolled 77 patients who underwent TUSPLA or SITPLA to provide more minimally invasive surgery between May 2017 and April 2018. TUSPLA was performed in 39 patients and 38 underwent SITPLA. In the SITPLA group, two 5-mm trocars were inserted through the umbilicus and an extra puncture site was used for a left-handed instrument. Demographic characteristics, operative data, and postoperative outcomes were collected and compared between the groups. RESULTS: The mean total operative time in the SITPLA group was shorter than in the TUSPLA group (p=0.003). The mean laparoscopic instrumental time was also shorter (p<0.001) in the SITPLA. The number of postoperative analgesics in the SITPLA group was less than in the TUSPLA group (p=0.002). The length of hospital day after surgery was shorter in the SITPLA group than in the TUSPLA group (p=0.008). There were no other significant differences between the groups. CONCLUSION: SITPLA had a shorter operative time, required less pain management, and had a similar cosmetic outcome when compared with TUSPLA.

Spare parts neoumbilicoplasty

Umbilical preservation can be challenging, particularly in complex cases involving simultaneous ventral hernia repair and abdominoplasty. Although the umbilicus serves no functional purpose, removal of the umbilicus can draw unwanted attention to the abdominal area and can cause emotional distress to patients. There are several well documented options for umbilical reconstruction. We present a new umbilical reconstruction technique relevant for such cases. This neoumbilicoplasty allows for preservation of the original umbilicus with relocation and reconstruction using local flaps. The technique is relatively simple and the time needed is minimal. The result is a natural, well positioned umbilicus using the principles of spare part surgery.

Immediate Umbilical Reconstruction after a Mohs Micrographic Surgery for Primary Cutaneous Adenoid Cystic Carcinoma Arising in the Umbilicus

Adenoid cystic carcinoma (ACC) is a malignant neoplasm of glands commonly occurs in salivary glands. Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare form of ACC that primarily presents on the skin. Herein, we represent a rare case of PCACC occurred in the umbilicus in a 66-year-old Korean male patient. The patient visited our center with erythematous indurated patch on the umbilicus diagnosed as ACC by incisional biopsy at another center. The diagnosis of PCACC was confirmed by additional histopathologic examination and imaging study. We proceeded Mohs micrographic surgery and reconstructed umbilicus with tacked purse string suture. Local recurrence and distant metastasis were not observed during 30-month follow-up. We report this rare case of PCACC on the umbilicus so that dermatologist can aware of the rare disease. Furthermore, we recommend MMS and tacked purse string suture as effective methods for treatment of PCACC and immediate umbilical reconstruction.
