ABSTRACT

La enfermedad herniaria inguinal de la niñez, comprende un grupo de afecciones de la región inguinal que tienen su génesis en fallos de la obliteración del conducto peritoneo vaginal o conducto vaginal. El propósito de los autores es compartir esta guía con los cirujanos pediátricos a través de su publicación, lo que les permitiría emplearla como referencia en sus instituciones. La enfermedad herniaria inguinal de la niñez, constituye la primera causa de operaciones electivas ‒programadas o planificadas‒ en unidades quirúrgicas pediátricas. Tiene una incidencia que varía entre 1 y 7 por ciento de la población infantil. En el IV Simposio Nacional de Cirugía Pediátrica (Varadero, Matanzas, 1- 3 de juliode 2019) se presentó, discutió y se aprobó esta guía de práctica clínica. Su aplicación en diferentes servicios de cirugía pediátrica beneficiaría a un gran número de niños con esta enfermedad, además de ser útil como orientación a profesionales encargados de la atención sanitaria a niños y adolescentes en la atención primaria de salud(AU)


Children´s inguinal hernia disease comprises a group of conditions in the groin region that have their genesis in failures of peritoneal vaginal duct obliteration or vaginal duct. The purpose of the authors is to share these guidelines with pediatric surgeons through its publication, which would allow them to use it as a reference in their institutions. Children´s inguinal hernia disease is the leading cause of elective operations, programmed or planned, in pediatric surgical units. It has an incidence ranging from 1 to 7 percent of the children population. At the IV National Symposium on Pediatric Surgery (Varadero, Matanzas, 1-3 July 2019) these clinical practice guidelines were presented, discussed and approved. Their application in different pediatric surgery services would benefit a large number of children with this disease, as well as being useful as guidance to professionals in charge of health care for children and adolescents in the primary health care level(AU)

ABSTRACT

Resumen Se presenta el caso de un paciente con antecedente de consumo crónico de alcohol, que consultó por dolor abdominal inespecífico, fiebre intermitente no cuantificada y pérdida de peso, con posterior aumento del perímetro abdominal. Se encontró ascitis y hallazgos en imágenes que sugerían cirrosis. El estudio del líquido ascítico fue no hipertensivo con predominio de linfocitos y niveles de adenosina-desaminasa (ADA) elevados. La ecografía y tomografía de abdomen mostraron el engrosamiento del peritoneo y la biopsia peritoneal por laparoscopia fue compatible con enfermedad granulomatosa, con reacción en cadena de la polimerasa (PCR) positiva para Mycobacterium tuberculosis en un paciente sin otras causas de inmunosupresión. Este caso muestra la necesidad de mantener una alta sospecha clínica de TB en patologías abdominales con clínica inespecífica, aun en pacientes sin inmunocompromiso claro.


Abstract This is the case of a patient with a history of chronic alcohol consumption, who consulted for nonspecific abdominal pain, intermittent fever, and weight loss, with subsequent increase in the abdominal perimeter. Ascites and imaging findings suggestive of cirrhosis were found. The study of ascitic fluid was non-hypertensive with a predominance of lymphocytes and elevated adenosine deaminase (ADA) levels. Ultrasound and abdominal tomography showed peritoneal thickening. Laparoscopic peritoneal biopsy was compatible with granulomatous disease, with positive PCR for Mycobacterium tuberculosis in a patient with no other causes of immunosuppression. This report shows the importance of keeping a high index of suspicion for TB in patients with abdominal pathology, even in those without evident inmunocompromise.

ABSTRACT

ABSTRACT Background: Since publication of our paper "Ten Golden Rules for a Safe MIS Inguinal Hernia Repair" we have received many questions. As the authors, we feel it is important to address these topics as a follow-up to our paper. Aim: To discuss in more details the main points of controversy, review the rules and update de recommendations. Method: The questions and discussions came mainly over five rules, numbered 3, 5, 6, 7, 10. We analyzed all the comments about recommendations and update some technical principles. Results: Rule 3 - Removing normal fat plugs from the obturator canal is unnecessary and therefore is not recommended; Rule 5 - transection of the uterine round ligament (1 cm proximal to the deep ring) facilitates adequate dissection. When performed in this way it does not appear to be associated with complications; Rule 6 - transection of huge sacs are safer than over-dissection of the cord structures. Whether dissecting completely the sac or abandon the distal part it results in less postoperative seromas is an ongoing debate; Rule 7 - any retroperitoneal structure traversing the internal ring is or play a role like a hernia. Failing to identify and remove the lipoma will ultimately result in the patient experiencing a recurrence; Rule 10 - in TAPP peritoneum should preferably be closed with suture than tackes. Conclusion: 10 Golden Rules emphasize the most important surgical tips and technical steps that allow the safe performance of MIS repairs of inguinal hernias, regardless the technique.


RESUMO Racional: Desde a publicação de nosso artigo "Dez Regras de Ouro para o Reparo Seguro de Hérnia Inguinal MIS", recebemos muitos questionamentos. Como autores, sentimos que é importante abordar esses tópicos como seguimento do artigo Objetivo: Discutir com mais detalhes os principais pontos de controvérsia, revisar as regras e atualizar as recomendações. Método: As dúvidas e discussões surgiram principalmente sobre cinco regras, numeradas 3, 5, 6, 7, 10. Analisamos todos os comentários sobre as recomendações e atualizamos alguns dos princípios técnicos. Resultados: Regra 3 - remoção dos plugs de gordura normais do canal obturador é desnecessária e, portanto, não é recomendada; Regra 5 - transecção do ligamento redondo do útero (1 cm proximal ao anel profundo) facilita a dissecção adequada e quando realizado dessa forma, não parece estar associada com complicações; Regra 6 - transecção de grandes sacos herniários é mais segura do que a dissecção excessiva das estruturas do cordão espermático e, se dissecar completamente o saco ou abandonar a parte distal, resulta em menos seromas pós-operatórios ainda é motivo de debate; Regra 7 - qualquer estrutura retroperitoneal que atravessa o anel interno é ou desempenha o papel como uma hérnia e deixar de identificar e remover o lipoma acabará resultando em recorrência; Regra 10 - na TAPP o peritônio deve ser fechado preferencialmente com sutura do que com tacks. Conclusão: As 10 Regras de Ouro enfatizam as dicas cirúrgicas e etapas técnicas mais importantes que permitem a realização segura de reparos MIS de hérnias inguinais, independentemente da técnica.

ABSTRACT

ABSTRACT Background: In the definition of the mesh to be used to correct hernias, porosity, amount of absorbable material and polypropylene should be considered in the different stages of healing process. Aim: To evaluate the inflammatory reaction in the use of macro and microporous meshes of high and low weight in the repair of defects in the abdominal wall of rats. Methods: Ninety Wistar rats (Rattus norvegicus albinus) were used. The animals were submitted to similar surgical procedures, with lesion of the ventral abdominal wall, maintaining the integrity of the parietal peritoneum and correction using the studied meshes (Prolene®, Ultrapro® and Bard Soft®). Euthanasia was performed at 30, 60 and 120 days after surgery. The abdominal wall segments were submitted to histological analysis using H&E, Masson's trichrome, immunohistochemistry, picrosirius red and tensiometric evaluation. Results: On the 120th day, the tensiometric analysis was superior with Ultrapro® macroporous mesh. The inflammatory process score showed a significant prevalence of subacute process at the beginning and at the end of the study. Microporous meshes showed block encapsulation and in macroporous predominance of filamentous encapsulation. Conclusion: The Ultrapro® mesh showed better performance than the others in healing process of the abdominal wall.


RESUMO Racional: Na definição da tela a ser utilizada na correção das hérnias deve-se considerar a porosidade, quantidade de material absorvível e polipropileno ou inabsorvível nas diversas fases da cicatrização. Objetivo: Avaliar a reação inflamatória das telas macro e microporosas de alta e baixa gramatura no reparo de defeito da parede abdominal de ratos. Método: Foram utilizados 90 ratos da raça Wistar (Rattus norvegicus albinus). Os animais foram submetidos a procedimentos cirúrgicos semelhantes, com lesão da parede abdominal ventral, mantendo a integridade do peritônio parietal e correção utilizando as telas Prolene®, Ultrapro® e Bard Soft®. Realizou-se a eutanásia aos 30, 60 e 120 dias de pós-operatório. Os segmentos da parede abdominal foram submetidos à análise histológica com H&E, tricômio de Masson, imunoistoquímica, picrosirius red e análise tensiométrica. Resultado: No 120º dia a análise tensiométrica mostrou superioridade da tela macroporosa Ultrapro®. O escore do processo inflamatório demonstrou prevalência significativa de processo subagudo no início e no final do estudo. As telas microporosas mostraram encapsulamento em bloco e as macroporosas encapsulamento predominantemente filamentar. Conclusão: A tela Ultrapro® mostrou melhor desempenho em relação às demais na cicatrização da parede abdominal.

ABSTRACT

Xenarthras (Mammalia, Dasypodidae) das espécies Dasypus novemcinctus e Euphractus sexcinctus tiveram sua anatomia científica estudada em relação à topografia dos intestinos delgado e grosso, suas relações peritoniais, morfologia externa e irrigação. Medidas dos diferentes segmentos intestinais e do número de vasos a eles destinados foram tomadas para fins comparativos. O método previu: fixação (formol 7%); injeção de látex; dissecação e fotodocumentação. Espacialmente, embora os intestinos sejam fixados por dupla membrana peritoneal, como em outros vertebrados, nestes a serosa conectou o duodeno, o jejuno, o íleo e os cólons em um único ligamento fixado no dorso do animal. Duodeno e pâncreas, intraperitoniais, como o reto, fixaram-se nas pelves maior e menor, respectivamente e dorsalmente. Vasos derivados do tronco celíaco mesentérico e da aorta percorreram o interior do mesoduodeno, do mesentério comum, do mesocólon e do mesorreto, estando estes, ao longo de seus trajetos, relacionados às cadeias linfonodulares intestinais. O modelo de rotação peritoneal, a morfologia externa, bem como o modelo de vascularização intestinal, foram interpretados como basais, diferindo dos vertebrados recentes, conforme o suporte literário.(AU)


Xenarthras (Mammalia, Dasypodidae) of the species Dasypus novemcinctus and Euphractus sexcinctus had their scientific anatomy studied in relation to the topography of the small and large intestines, their peritoneal relationships, external morphology and irrigation. Measurements of the different intestinal segments and the number of vessels destined for them were taken for comparative purposes. The method predicted: fixation (7% formaldehyde); latex injection; dissection and photo documentation. Spatially, the intestines, although fixed by a double peritoneal membrane, as in other vertebrates, in these, the serosa connected the duodenum, jejunum, ileum, and the colon in a single ligament fixed to the animal's back. Duodenum and pancreas, intraperitoneal, like the rectum, were fixed in the major and minor pelvis respectively and dorsally. Vessels derived from the mesenteric celiac trunk and the aorta traveled through the interior of the mesoduodenum, common mesentery, mesocolon and mesoride, being related to the lymph node chains along their pathways. The peritoneal rotation model, the external morphology as well as the model of intestinal vascularization were interpreted as basal, differing from recent vertebrates, according to literary support.(AU)

ABSTRACT

Com o objetivo de promover, por meio de acesso único e com o uso de endoscópio flexível, ampla exploração da cavidade peritoneal de equinos em estação, foi concebida uma cânula laparoscópica para dar sustentação ao endoscópio e possibilitar o acesso sob visualização. O procedimento foi realizado a partir da fossa paralombar. Após pequena incisão cutânea, o endoscópio foi inserido na cânula e os músculos e o peritônio foram divulsionados mediante rotação da cânula. Logo depois da perfuração do peritônio, foi realizada a exploração da cavidade e a identificação das estruturas. Em seguida à exploração do lado ipsilateral ao acesso, realizou-se a transposição do conjunto cânula/endoscópio ventralmente à porção caudal do cólon descendente, seguida de exploração do lado contralateral. Concluída a técnica, foi executado, para fins de comparação, o mesmo procedimento por meio da fossa paralombar contralateral. Foi possível a transposição do conjunto cânula/endoscópio para o lado contralateral ao acesso em todos os procedimentos. Também foi possível a identificação da maioria das estruturas abdominais tanto pelo acesso esquerdo quanto pelo direito. A abordagem por acesso único mostrou-se viável para a exploração ampla da cavidade peritoneal, demonstrando ser uma alternativa à técnica laparoscópica convencional.(AU)


A laparoscopic cannula was designed to support a single access approach with a flexible endoscope for the wide exploration of the peritoneal cavity of standing horses. It provides support to the endoscope and allows access to the peritoneal cavity with a visual aid. This procedure was performed through the paralumbar fossa. After a small cutaneous incision, the endoscope was inserted into the cannula, and the muscles and peritoneum were divulsed through the rotation of the cannula. After the peritoneal perforation, cavity exploration and identification of structures were performed. After the exploration of the ipsilateral side of the access, the cannula/endoscope was transposed ventrally to the caudal portion of the descending colon; this was followed by the exploration of the contralateral side. Once this process was completed, the same procedure was performed through the contralateral paralumbar fossa for comparison. It was possible to transpose the cannula/endoscope set to the contralateral access side in all procedures. Further, it was possible to identify most of the abdominal structures in both the left and right access. This single access approach proved to be feasible for the extensive exploration of the peritoneal cavity, thereby indicating it can be an alternative to the conventional laparoscopic technique.(AU)

ABSTRACT

A túnica vaginal possui características ideais para enxertia e já foi empregada na reparação de diversos tecidos, inclusive do diafragma pélvico. Objetivou-se avaliar a aplicabilidade da túnica vaginal como enxerto autógeno livre, em dupla camada, para a reparação do diafragma pélvico em 14 cães portadores de hérnia perineal, das quais, nove eram unilaterais e cinco, bilaterais. Após a orquiectomia, as túnicas de ambos os testículos foram coletadas, sobrepostas e fixadas entre si por meio de quatro pontos de reparo. Foi realizada abordagem ao saco herniário, inspeção, redução do conteúdo herniário, desbridamento muscular e síntese primária mediante sutura. O enxerto foi fixado à musculatura remanescente por meio de pontos simples separados e, posteriormente, encoberto pela sutura intradérmica e por síntese cutânea. Observações transoperatórias e, posteriormente, avaliações clínicas e ultrassonográficas, por período de um ano, permitiram sugerir que a túnica vaginal possui atributos ideais para a reparação do diafragma pélvico. Conclui-se que o enxerto autógeno livre de túnica vaginal, em dupla camada, é exequível e aplicável para o reparo do diafragma pélvico no tratamento da hérnia perineal em cães.(AU)


The tunica vaginalis has ideal characteristics for grafting and has already been used to repair several tissues, including the pelvic diaphragm. The aim of this study was to evaluate the applicability of the tunica vaginalis as a free double-layer autogenous graft to repair the pelvic diaphragm in 14 dogs with perineal hernia, of which, nine were unilateral and five, bilateral. After orchiectomy, the tunics of both testicles were collected, overlapped and fixed to each other by four repair points. The hernial sac was approached, followed by inspection, reduction of the hernia content, muscle debridement and primary synthesis through suture. The graft was attached to the remaining musculature by simple interrupted stitches and later hidden by intradermal suture and cutaneous synthesis. Intraoperative observations and, later, clinical and sonographic evaluations over a one-year period, allow to suggest that the tunica vaginalis has ideal attributes for the pelvic diaphragm repair. It is concluded that the autogenous graft-free of tunica vaginalis in double layer is feasible and applicable in order to repair the pelvic diaphragm in the perineal hernia treatment in dogs.(AU)

ABSTRACT

Introducción. La hernia paracecal es una entidad rara que corresponde al 13 % de todas las hernias internas. Aunque algunas pueden ser adquiridas, pero la mayoría son congénitas y se originan en los recesos creados durante la adherencia y fusión de los repliegues peritoneales alrededor de la región ileocecal. Caso clínico. Se trata de un hombre de 42 años de edad a quien se le diagnosticó una apendicitis aguda. La in-tervención quirúrgica se inició con una incisión para apendicectomía localizada; no obstante, por los hallazgos intraoperatorios, se decidió la conversión a laparotomía y se produjo el hallazgo incidental de una hernia paracecal.Resultados. El paciente fue hospitalizado y, en el quinto día postoperatorio, presentó obstrucción intestinal por lo cual fue intervenido nuevamente; se encontró escaso líquido de reacción peritoneal y adherencias. Se le dio el egreso hospitalario cuatro días después de su segundo procedimiento quirúrgico y continuaba asintomático hasta su último control.Discusión. Las hernias paracecales son hernias internas que se describen como la protrusión de una víscera hueca por una apertura mesentérica o peritoneal. Sus manifestaciones clínicas son variadas y se puede presentar sin síntomas, con dolor abdominal localizado o hasta con obstrucción intestinal. El tratamiento quirúrgico se basa en liberar y examinar el segmento intestinal herniado y, de requerirse, proceder a la resección con anastomosis; se debe resecar el saco herniario cuando sea evidente, valorar los vasos mesentéricos y cerrar el defecto herniario. Se trata de una enfermedad poco común y es importante conocer su manejo con la finalidad de evitar complicaciones, ya que continúa siendo un reto diagnóstico para el cirujano.


Introduction: Paracecal hernia is a rare entity that represents 13% of all internal hernias. Although some may be acquired, most are congenital and originate in the recesses created during the adhesion and fusion of peritoneal folds around the ileocecal region.Clinical case: This is a 42-year-old man who was diagnosed with acute appendicitis. The surgical intervention began with an incision for localized appendectomy; however, due to intraoperative findings, conversion to laparotomy was decided and the incidental finding of a paracecal hernia occurred. The patient was hospitalized and, on fifth postoperative day presented intestinal obstruction, for which he was reoperated; little peritoneal reaction fluid and adhesions were found. He was discharged four days after his last surgical procedure and remained asymptomatic until his last control.Discussion: Paracecal hernias are internal hernias that are described as the protrusion of a hollow viscera throu-gh a mesenteric or peritoneal opening. Its clinical manifestation are varied and can present without symptoms, with localized abdominal pain or even intestinal obstruction. Surgical management is based on releasing and examining the herniated intestinal segment and, if required, proceed with resection with anastomosis. The hernia sac should be resected when evident, assess the mesenteric vessels and close the hernia defect. It is a rare pathology and it is important to know its management in order to avoid complications, as it continues to be a diagnostic challenge for the surgeon

ABSTRACT

To develop an ideal surgical procedure for neobladder reconstruction in experimental porcine models. Six experimental female pigs weighting 28-33 kg underwent transplantation of autologous peritoneum for bladder reconstruction under general anesthesia.The flaps were used to reconstruct the orthotopic neobladder by suturing with the edges of the triangle and neck of the remnant bladder.The ureteral catheters were removed on the 5 postoperative day and the balloon catheter was removed on the 7 postoperative day.Voiding behaviour was monitored.The animals were euthanized at week 12 for routine pathology,immunohistochemistry,and electron microscopy. All the pigs survived after the surgery,and no postoperative complication such as peritonitis,intestinal obstruction,or urinary fistula was observed.All the peritoneum-ileum composite free valves survived after transplantation.Voiding behaviour was normal after catheter removal,and the urine was clear.At autopsy,reconstructed bladders were healthy.Pathological examination showed the neobladder had been covered by continuous urothelium while the peritoneum disappeared and showed no ileal mucosa regrowth and residual.Scanning electron microscope showed the transitional cells of neobladder were complete and orderly,and the urothelium around suture border was continuous and showed no malposition. Reconstruction of bladder by autologous peritoneum and ileal seromuscular flaps is an ideal approach in the experimental pigs as it can prevent regrowth of ileal epithelial cells and avoid the complications of conventional enterocystoplasty.Its clinical application deserves further investigations.

ABSTRACT

Encapsulating peritoneal sclerosis (EPS) is a rare but severe complication of peritoneal dialysis. A total of 50% of the patients died within 12 months after being diagnosed. There are no obvious clinical symptoms in the early stage of EPS, which is easy to be missed. And there are few case reports of EPS in early stage. On December 22, 2018, a 70-year-old male patient undergoing peritoneal dialysis for 17 months, who was diagnosed as EPS, was admitted to the Department of Nephrology, the Third Xiangya Hospital, Central South University. The patient's peritoneal dialysis catheter was obstructed after peritonitis. The peritoneal dialysis fluid couldn't be drain in and out of the abdominal cavity. Therefore, the laparoscopy was performed to repair the catheter. The operation in progress showed that the peritoneum was slightly thickened and the ileocecal intestinal tube was closely adhered to the parietal peritoneum where the catheter was wrapped, indicating the early stage of EPS. Peritoneal relaxation was performed. The patient's catheter was normal after adhesiolysis. He underwent hemodialysis, nutritional supporting as well as peritoneal dialysis transition, etc. The peritonitis was controlled after 10 days and the peritoneal dialysis was resumed. After discharge from hospital, the patient took moxifloxacin for 2 more weeks. We followed up the patient for 6 months. The automated peritoneal dialysis is maintained, and everything remains normal. Clinicians need to improve understanding of EPS. Early diagnosis and laparoscopic adhesiolysis is helpful to continue peritoneal dialysis treatment.

ABSTRACT

Introducción: la citorreducción más quimioterapia hipertérmica intraoperatoria (HIPEC) aborda la carcinomatosis peritoneal (CP) como una enfermedad locorregional, con respuesta adecuada en la supervivencia considerando la severidad de la patología. La agresividad del procedimiento se asocia con altos índices de morbimortalidad. Objetivo: evaluar la supervivencia global y libre de enfermedad a 1 año en pacientes con CP, en quienes se realizó tratamiento mediante citorreducción más HIPEC en el Hospital Infantil Universitario de San José entre enero 2016 y diciembre 2017. Metodología: estudio observacional de una cohorte con CP de diferentes etiologías que recibieron citorreducción más HIPEC, se obtuvo información a partir de las historias clínicas. Resultados: se incluyeron 10 casos con una mediana de edad de 49 años (RIC 43-54) y CP de origen primario en apéndice (60%, n=6), colon (20%, n=2) y ovario (20%, n=2). El índice de carcinomatosis peritoneal (ICP) presentó una mediana de 14.5 (RIC 6-24). Se observó recaída en 3 pacientes y 4 desenlaces fatales. Se estimó una supervivencia global de 54% y libre de enfermedad de 58% a un año. Conclusión: se encontraron mejores resultados en supervivencia global y libre de enfermedad a un año que los descritos en quimioterapia sistémica. Es importante la selección estricta de los pacientes, así como efectuar estudios con un mayor número para determinar con evidencia la relación entre el procedimiento y la supervivencia global y libre de enfermedad.


Introduction: cytorreductive surgery (CRS) paired with hyperthermic intraoperative chemotherapy (HIPEC), approach peritoneal carcinomatosis (PC) as a localized regional disease with adequate survival response according to disease severity. CRS with HIPEC is regarded as a highly morbid procedure with high mortality rates. Objective: to review the 1-year overall survival and disease-free survival in patients with PC that had been treated with CRS with HIPEC at Hospital Infantil Universitario de San José between January 2016 and December 2017. Methodology: an observational study analyzing a cohort of patients with PC secondary to various primary tumors who received CRS with HIPEC. Data was collected from clinical records. Results: we included 10 cases with mean age of 49 years (IQR 43-54) and PC secondary to appendix (60%, n=6), colon (20%, n=2) and ovary (20%, n=2) primary tumors. The peritoneal carcinomatosis index (PCI) was 14.5 (IQR 6-24). PC recurred in 3 patients and 4 patients died. A 1-year overall survival rate of 54% was estimated and a 1-year disease-free survival of 58% was obtained. Conclusion: our results of 1-year overall and disease-free survival rates were better to those described for systemic chemotherapy. Strict patient selection, as well as, conducting larger studies is recommended to allow an evidence-based determination of overall and disease-free survival in patients treated with CRS with HIPEC.

ABSTRACT

In this work the quantitative data of the surfaces that limit the sub-spaces that constitute the peritoneal space are shown. The methodology of measurement of the two sheets (parietal and visceral) of the peritoneal serosa applied in our previous paper (Albanese et al., 2009), in non-eviscerated corpses, allowed us to know for the first time, the surface or total extension of the peritoneum "in situ". This methodology was useful to determine the surface or area of the two sheets of the peritoneum, which limit the peritoneal space. Our objective in this study was to determine the total peritoneal areas (visceral + parietal) in human corpses that are not eviscerated, which limit the different sub-spaces that make up the peritoneal space. Ten female cadavers fixed in 5 % formaldehyde solution were used. Small cellophane films were placed directly on the peritoneal sheets. The digital images were obtained by scanning these models. The surface was determined by the "Scion image for Windows" program. The results were expressed as mean +/- SE. The analysis of variance (ANOVA) was used for the statistical study. The results obtained showed that the peritoneal sub-space of greater surface area was retro-omental (mean +/- SE 7767.81 +/- 646.70 cm2 p <0.01 ANOVA), due to the large extension of its visceral surface ( mean +/- SE 7401.82 +/- 640.99 cm2). More than 50 % of the surface of the entire peritoneum corresponds to said sub-space. The smallest peritoneal sub-space (3 % of the total peritoneal surface) was the pelvic sub-space (mean +/- SE 431.30 +/- 41.62 cm2). We believe that this information may be useful in case of peritoneal pathological processes or those affected by prolonged peritoneal dialysis, and that knowledge of the surface and extension of the peritoneal space involved may contribute to the estimation of the peritoneal surface involved and help to plan the treatment.


En este trabajo se muestran los datos cuantitativos de las superficies que limitan el espacio peritoneal y los sub-espacios que lo componen. La metodología de medición de las dos hojas (parietal y visceral) de la serosa peritoneal empleada en cadáveres no eviscerados, permitió conocer por primera vez, la superficie o extensión total del peritoneo in situ. El objetivo en este trabajo fue determinar -en cadáveres humanos no evisceradoslas áreas peritoneales totales (visceral + parietal) que limitan los distintos sub-espacios que conforman el espacio peritoneal. Se han utilizado diez cadáveres femeninos no eviscerados fijados en solución de formaldehido al 5 %. Pequeñas películas de celofán se colocaron directamente sobre las hojas peritoneales. La obtención de imágenes digitales se realizó escaneando estos modelos. La superficie fue determinada por el programa "Scion image for Windows". Los resultados se expresaron como media +/- SE. Para el estudio estadístico se utilizó el análisis de varianza (ANOVA). Los resultados obtenidos demostraron que el sub-espacio peritoneal de mayor superficie fue el retro-omental (media +/- SE 7767,81 +/ - 646,70 cm2 p<0.01 ANOVA), debido a la gran extensión de su superficie visceral (media +/- SE 7401,82 +/- 640,99 cm2). Más del 50 % de la superficie de todo el peritoneo corresponde a dicho sub-espacio. El sub-espacio peritoneal más pequeño (3 % de la superficie peritoneal total) fue el sub-espacio pélvico (media +/SE 431,30 +/- 41,62 cm2). Esta información podrá ser de utilidad en el caso de procesos patológicos peritoneales o áreas afectadas por diálisis peritoneal prolongada. De esta manera el conocimiento de la extensión del espacio peritoneal involucrado, puede contribuir a la estimación de la magnitud y gravedad de la superficie peritoneal comprometida. Además puede ayudar a planificar el tratamiento.

ABSTRACT

RESUMEN OBJETIVO: Comparar la resultante materna a corto plazo del cierre o no del peritoneo durante la cesárea. MÉTODOS: Se realizó un estudio al azar, doble ciego y controlado en embarazadas que asistieron al Hospital Central "Dr. Urquinaona", Maracaibo, Venezuela. Las pacientes seleccionadas se asignaron al azar al grupo A (grupo no intervenido, cirugía sin cierre peritoneal) y Grupo B (grupo intervenido, cirugía con cierre peritoneal). Se evaluaron características generales, duración de la cirugía, concentraciones de hemoglobina posterior a la cirugía, duración de la hospitalización, dolor post-operatorio, necesidad de analgesia de rescate y frecuencia de complicaciones post-operatorias. RESULTADOS: Se seleccionaron para el análisis final 247 pacientes en el grupo A y 248 pacientes en el grupo B. Se observó que las pacientes del grupo A presentaban duración de la cirugía significativamente menor comparado con las pacientes del grupo B (p < 0,0001). No se observaron diferencias en valores de hemoglobina post-operatoria, tiempo de hospitalización, intensidad de dolor postoperatorio, aparición de ruidos hidroaéreos y complicaciones post-operatorias (p = ns). CONCLUSIÓN: No realizar la peritonización no parece tener efectos negativos sobre la resultante materna a corto plazo en comparación con los casos en las que si se realiza.


ABSTRACT OBJECTIVE: To compare short-term maternal outcome of the closure or not of peritoneum during cesarean section. METHODS: A randomized, double-blind and controlled study was conducted on pregnant women who attended at Hospital Central "Dr. Urquinaona", Maracaibo, Venezuela. The selected patients were randomly assigned to group A (non-intervened group, surgery without peritoneal closure) and group B (intervened group, surgery with peritoneal closure). General characteristics, duration of surgery, hemoglobin concentrations after surgery, duration of hospitalization, post-operative pain, need for rescue analgesia and frequency of postoperative complications was evaluated. RESULTS: A total of 247 patients in group A and 248 patients in group B were selected for the final analysis. It was observed that patients in group A had a significantly shorter duration of surgery compared to patients in group B (p <0.0001). No differences were observed in postoperative hemoglobin values, hospitalization time, postoperative pain intensity, return of bowel movements and post-operative complications (p = ns). CONCLUSION: To not perform peritonization does not appear to have negative effects on the short-term maternal outcome compared with cases which it is done.

ABSTRACT

Abstract Purpose: To evaluate the effects of the nutraceuticals omega-6/3 and omega-9/6 on endometriosis-associated infertility and pain. Methods: Controlled experimental study, with each group composed of eight female rats. Fertility groups: sham-operated control (0.9% saline solution); control with endometriosis (0.9% saline); omega-6/3 (1.2 g/kg/day); omega-9/6 (1.2 g/kg/day); and meloxicam (0.8 mg/kg/day). Pain groups: sham-operated control (0.9% saline); control with endometriosis (0.9% saline); omega-6/3 (1.2 g/kg/day); omega-9/6 (1.2 g/kg/day); medroxyprogesterone acetate (5 mg/kg/every 3 days); and meloxicam (0.8 mg/kg/day). Peritoneal endometriosis was surgically induced. Pain was evaluated with the writhing test. Fertility was evaluated by counting the number of embryos in the left hemi-uterus. Results: The mean number of writhings was as follows: sham-operated, 11.1 ± 2.9; control with endometriosis, 49.3 ± 4.4; omega-6/3, 31.5 ± 2.7; omega-9/6, 34.1 ± 4.5; medroxyprogesterone acetate, 2.1 ± 0.8; meloxicam, 1 ± 0.3. There was a significant difference between both controls and all drugs used for treatment. Regarding fertility, the mean values were as follows: sham-operated, 6.8 ± 0.6; control with endometriosis, 4.2 ± 0.7; omega-6/3, 4.7 ± 1; omega-9/6, 3.8 ± 0.9; and meloxicam, 1.8 ± 0.9. Conclusions: The omega-6/3 and omega-9/6 nutraceuticals decreased pain compared to the controls. There was no improvement in fertility in any of the tested groups.

ABSTRACT

Diastasis recti is a state with separated aponeurosis between two recti caused by weakening of the intercrossing fibers in the linea alba and it causes abdominal protrusion. Common causes comprised of increased intraabdominal pressure, or congenital weakening of myoaponeurotic layer. We describe a patient who underwent laparoscopic repair of diastasis recti. A 30-year-old woman was referred to our outpatient department for an abdominal mass that had appeared 1 year earlier. Physical examination revealed an abdominal wall defect along the midline and computed tomography showed thinning and stretching of the linea alba. The patient underwent laparoscopic repair for diastasis recti. The stretched linea alba was approximated using interrupted sutures from the epigastrium to the suprapubic area. A dual mesh was applied below the peritoneum to prevent recurrence. The patient was discharged without complications, and was followed up for 1 year without recurrence. Laparoscopic repair could be a considerable is a treatment modality for diastasis recti.

ABSTRACT

A differential diagnosis of ascites is always challenging for physicians. Peritoneal tuberculosis is particularly difficult to distinguish from peritoneal carcinomatosis because of the similarities in clinical manifestations and laboratory results. Although the definitive diagnostic method for ascites is to take a biopsy of the involved tissues through laparoscopy or laparotomy, there are many limitations in performing biopsies in clinical practice. For this reason, physicians have attempted to find surrogate markers that can substitute for a biopsy as a confirmative diagnostic method for ascites. CA 125, which is known as a tumor marker for gynecological malignancies, has been reported to be a biochemical indicator for peritoneal tuberculosis. On the other hand, the sensitivity of serum CA 125 is low, and CA 125 may be elevated due to other benign or malignant conditions. This paper reports the case of a 66-year-old male who had a moderate amount of ascites and complained of dyspepsia and a febrile sensation. His abdominal CT scans revealed a conglomerated mass, diffuse omental infiltration, and peritoneal wall thickening. Initially, peritoneal tuberculosis was suspected due to the clinical symptoms, CT findings, and high serum CA 125 levels, but non-specific malignant cells were detected on cytology of the ascitic fluid. Finally, he was diagnosed with primary malignant peritoneal mesothelioma after undergoing a laparoscopic biopsy.

ABSTRACT

Sarcomatoid mesothelioma is not very common, mesothelioma is directly attributable to occupational asbestos exposure, with 90% of cases showing a history of exposure. A 66-year-old male was admitted with an abdominal pain that persisted for 3 weeks. He had no abdominal mass. Computed tomography showed soft tissue thickening in perihepatic space and nodularities in omentum and peritoneum with ascites. There was no absolute diagnosis evidence in ascites analysis. Although the pathology of ascites was free for malignancy, the patient underwent omentum biopsy for definitive diagnosis. In laproscopic exploration, there was omental cake, peritoneal nodular seeding. It was suspected cancer carcinomatosis. Immunohistochemical findings suggested that it was sarcomatoid masothelioma. This is the rare case of a peritoneal sarcomatoid mesothelioma, without any exposure to asbestos.
