Alterações do sistema de fibras elásticas relacionadas ao envelhecimento do ligamento interfoveolar
Universidade de São Paulo. Faculdade de Medicina, 2000Co-Authors: Quintas, Mario Luiz, Jin Hwan Yoo, Rodrigues, Consuelo Junqueira, Rodrigues Junior, Aldo JunqueiraAbstract:In order to evaluate age related changes of the elastic fiber system in the interfoveolar ligament, we studied the Deep Inguinal Ring from 33 male cadavers aged from stillborn to 76 years. Selective and alternated staining methods for elastic fibers were performed to differentiate oxytalan, elaunin, and mature elastic fibers. We confirmed quantitative changes of the elastic fiber system with aging. There was a significant and progressive reduction of the oxytalan fibers (responsible for tissue resistance) and a significant increment in the mature elastic and elaunin fibers (responsible for tissue elasticity). Furthermore, there were structural changes in the thickness, shortness and curling of these mature elastic fibers. These changes induced loss of the elastic fiber function and loss of the interfoveolar ligament compliance. These factors predispose individuals to the development of indirect Inguinal hernias that frequently emerge in adults and aged individuals, especially above the fifth decade.Com o objetivo de avaliar as alterações do sistema de fibras elásticas relacionadas ao envelhecimento do ligamento interfoveolar estudou-se o anel Inguinal profundo em 33 cadáveres do sexo masculino com idade variando de recém-nascido a 76 anos. Métodos de coloração seletiva para as fibras elásticas foram empregados para diferenciar fibras oxitalânicas, fibras elaunínicas e fibras elásticas maduras. Verificaram-se alterações quantitativas significantes no sistema de fibras elásticas do ligamento interfoveolar com o envelhecimento: uma redução progressiva de fibras oxitalânicas, responsáveis pela resistência do tecido conjuntivo, e um aumento de fibras elásticas maduras e elaunínicas, responsáveis pela elasticidade tecidual. Demonstraram-se alterações estruturais, como espessamento, encurtamento e encurvamento das fibras elásticas maduras e elaunínicas. Estas alterações induzem a perda de função das fibras elásticas, o que certamente levará a perda de complacência do ligamento interfoveolar, predispondo à hérnia Inguinal indireta, que freqüentemente aparece em homens adultos ou idosos, especialmente acima de 50 anos de idade

mature teratoma arising from an intra abdominal undescended testis presenting as a fetal abdominal mass
Ultrasound in Obstetrics & Gynecology, 1997Co-Authors: H H Shih, Rujeng Teng, K Tsou I Yau, Hohsiung Lin, Fonjou Hsieh, C C ChenAbstract:Teratoma of the intra-abdominal testis is a rare finding in infants. We describe the case of a full-term newborn treated for a calcified abdominal mass which was observed unexpectedly on prenatal sonography. An undescended right testis was also noted. DuRing laparotomy, a twisted retroperitoneal tumor was found just above the right Deep Inguinal Ring. Histological analysis revealed a mature teratoma of the intra-abdominal right testis. The tumor was removed and there was no recurrence at follow-up 1 year later. A teratoma should be considered in cases of fetal abdominal mass, especially when the testes cannot be detected in the scrotum by the 8thg month. Prenatal sonographic diagnosis might be possible.

scrotal enterocutaneous fistula a rare initial presentation of Inguinal hernia
Journal of Surgical Case Reports, 2014Co-Authors: Puneet Malik, Mahendra Rathi, Krishan Kumar, Rajeev Sharma, Pawan Meena, Ayush Arya, Rajveer AryaAbstract:We describe the case of a 70-year-old man with a long history of Inguinal hernia who finally presented to the emergency department with a scrotal enterocutaneous fistula. This is a rare complication of an incarcerated/obstructed direct Inguinal hernia. We performed exploratory laparotomy with resection of the perforated small bowel and end-to-end anastamosis of the ileal segment using the purse-stRing suture at the Deep Inguinal Ring.
