RESUMO

Colorectal cancer (CRC) is the fourth most frequently diagnosed cancer in the United States and it is found in 17% of patients thought to have complicated diverticular disease. However, primary adenocarcinoma rarely occur in the colostomy site and the risk of developing malignancy is similar to that of any other colonic segment. Polyps found in CRC screenings can be divided into the following types: hyperplastic polyps, polyps with no malignant potential, adenomatous polyps, polyps with malignant potential, and malignancies. Local complications of the colostomy can appear in the immediate, early, or late postoperative period, with an incidence ranging from 15 to 30%; neoplasia is even less common. (AU)

RESUMO

In this study, we describe, compare, and discuss several subcellular alterations found in Colorectal Adenocarcinoma and peritumoral tissue using transmission electron microscopy, morphometry, and statistical analysis. Tissue samples from anterior resections were collected from patients diagnosed with Colorectal Adenocarcinoma in the University Hospital of Caracas. Samples were processed according to the typical protocol for their observation through transmission electron microscopy. The resulting images were analyzed using specialized software for the collection of morphometric data. Several anomalies were common for both tissues, including but not limited to, rough endoplasmic reticulum and mitochondrial swelling, nuclear invagination, nuclear enlargement, and cellular swelling. In general, alterations within the tumor were more frequent and intense. Extensive organellar degradation and other evidences of cellular damage seemed to extend past the edge of the tumor into the peritumoral tissue. There seems to be a clear process of lateral cancerization present in the peritumoral area. The tissue layers composed of smooth muscle cells, probably due to their structural features, may allow greater diffusion of harmful substances produced by the tumor. A more in-depth analysis of peritumoral tissue considering organellar damage and morphometric data may provide relevant insight about the changing microenvironment promoted by the close proximity of a tumor.

RESUMO

ABSTRACT Objective: Transanal repair of rectocele and full rectal mucosectomy with one circular stapler is a procedure designed for the treatment of Obstructive Defecation Syndrome by doctor Fco. Sergio Regadas in 2005. We compare the use of multiple instruments and their mechanical technology effect in the treatment of anorectocele. Patients and methods: Female patients complaining about sensation of incomplete evacuation, ages between 40 and 55. The evaluation was made with the function of evacuation protocol: colonic transit time, colon radiology, ecodefecography, anorectal manometry and psychological test. The technique used was transanal repair of rectocele and full rectal mucosectomy with one circular stapler, using staplers CPH-34, CPH-34HV and EEA-3135-HEM, with measurement of the rectal wall resected: vertical length in centimetres, horizontal length in centimetres, weight in grams and volume in cubic centimetres; afterwards histological study of the tissue thickness, and applied the ANOVA and SPSS 12 tests for the statistical analysis. Results: The results obtained by comparing the resections made with the CPH-34, the CPH-34HV and the EEA-3135-HEM in respect of vertical length, horizontal length, weight and volume, were found to have no significant differences; neither in the histological study of the tissue thickness in respect of characteristics and structure. Conclusion: The effect of mechanical technology in the treatment of anorectocele with transanal repair of rectocele and full rectal mucosectomy with one circular stapler procedure using the CPH-34, the CPH-34HV and the EEA-3135-HEM, does not show any difference. Leaving the application of each to the operator competencies.

RESUMO

La secuencia Robin, previamente conocida como síndrome de Pierre Robin, se caracteriza por la presencia de micrognatia o retrognatia, glosoptosis con o sin fisura palatina. Los recién nacidos con este síndrome, pueden presentar obstrucción de la vía aérea, dificultad para la alimentación, retraso del crecimiento e hipoxemia crónica. La mitad de estos pacientes presentan malformaciones asociadas. La incidencia es aproximadamente de 1: 8,500. Las opciones actuales del tratamiento de la obstrucción de la vía aérea en estos pacientes, van desde la posición prona, intubación nasofaríngea, glosopexia con adhesión labial, distracción mandibular hasta la traqueostomía. Se presentó una variante de tratamiento quirúrgico de urgencia realizada a un recién nacido portador de una secuencia Robin con dificultad respiratoria. Se realizó una labio-glosopexia de Routledge. El paciente tuvo una evolución postoperatoria favorable sin dificultades en su ventilación y alimentación.


The Robin sequence, previously known as Pierre Robin syndrome, is charaterized by the presence of micrognathia or retrognathia, glossoptosis with or without cleft palate. The newborns with this syndrome may present airway obstruction, feeding difficulties, growth retardation and chronic hypoxemia. Half of these patients have associated malformations. The incidence is almost 1: 8 500. The current options for the treatment of the airway obstruction in these patients range from prone position, nasofaringeal intubation, glossopexy with lip adhesion, mandibular distraction up to tracheostomy. We presented a variant of emergency surgical treatment carried out in a newborn having a Robin sequence with respiratory difficulty. A Routledge´s lip-glossopexy was made. The patient had a favorable post-surgery evolution in his ventilation and feeding.

RESUMO

Abstract Objective This study aims to determine changes in the proportions of types I and III collagen in hemorrhoids and to verify the sliding anal canal lining theory. Patients and method The study is focused on a sample of 17 patients, 9 females and 8 males (age range: 30-70 years), with grade III and grade IV hemorrhoids. Tissue from 4 fetuses (age: 16 weeks of gestation) was used as control sample. All the participants gave their informed consent. Samples were gathered in 2014. All patients underwent open hemorrhoidectomy by using the technique described by Milligan and Morgan, published in Lancet journal in 1937. The hemorrhoid samples were stained with hematoxylin-eosin for the histologic study to confirm the hemorrhoidal tissue diagnosis. The picrosirius red staining protocol was used after the histologic analysis. The method used for image processing is described in the text. Images were imported to the Image Tool for Windows software. The same process was used on the embryonic tissue. Data resulting from the analysis of images were processed using STATISTICA, a software for statistical analysis. Results When compared, it was found that the two tissues presented very different values, with hemorrhoids containing the highest type III collagen values. Conclusion Our results seem to imply that hemorrhoids have a larger proportion of type III collagen than fetal tissue. They also suggest a possible age-related deterioration of the tissue.


Resumo Objetivo Esse estudo tem por objetivo determinar mudanças nos percentuais do colágeno dos tipos I e III em hemorroidas e verificar a teoria do revestimento de canal anal deslizante. Pacientes e método O estudo está focado em uma amostra de 17 pacientes (9 mulheres e 8 homes; faixa etária: 30-70 anos), com hemorroidas de graus III e IV. Utilizamos tecido de quatro fetos (idade: 16 semanas de gestação) como amostra de controle. Todos os participantes deram consentimento informado. As amostras foram reunidas em 2014. Todos os pacientes passaram por uma hemorroidectomia aberta; para tanto, foi empregada a técnica descrita por Milligan e Morgan, publicada no periódico Lancet em 1937. As amostras de hemorroida foram coradas com hematoxilina-eosina com vistas ao estudo histológico para confirmação do diagnóstico de tecido hemorroidal. Após a análise histológica, o material foi corado com o protocolo de picrosirius red. O método empregado para o processamento das imagens está descrito no texto. As imagens foram importadas pelo software Image Tool for Windows. O mesmo processo foi empregado no tecido embrionário. Os dados resultantes da análise das imagens fora processados com o programa STATISTICA, um software para análise estatística. Resultados Por comparação, constatamos que os dois tecidos apresentavam valores muito diferentes, e as hemorroidas continham os mais altos valores de colágeno do tipo III. Conclusão Nossos resultados parecem implicar que hemorroidas possuem um percentual mais elevado de colágeno do tipo III versus tecido fetal. Os resultados também sugerem uma possível deterioração do tecido, relacionada à idade.

RESUMO

Objetivo: Presentar la aplicación de la tecnología láser en el tra-tamiento de la enfermedad hemorroidal. Estudio realizado en cen-tro privado, y en la Unidad de Coloproctología del HospitalUniversitario de Caracas, Métodos: En el período comprendidoentre junio 2012 y agosto 2013 se estudió un total de 35 pacien-tes todos con problemas hemorroidales con criterios quirúrgicos(sangrado, prolapso, dolor). Del total de pacientes, 7 casos fuerontratados de emergencia y 28 casos fueron electivos. El equipo uti-lizado fue un láser diodo marca Velas de 30W y en una oportu-nidad se utilizó un equipo de láser CO2 DEKA. Los pacientes fue-ron informados previamente sobre la utilización del instrumentalláser, lo cual aprobaron. Se evaluó el tiempo de cirugía, el sangradointraoperatorio y postoperatorio, el dolor postoperatorio, el tiem-po de zicatrización y la reincorporación a las actividades cotidia-nas. Resultados: Se evidenció dolor postoperatorio en un valorde 4 a 6 puntos (tomando como referencia la escala analógica deldolor de 1 al 10) lo cual disminuyó posterior a la primera semanadel postoperatorio. El sangrado intraoperatorio disminuyó alrede-dor de un 80%. El tiempo de cicatrización disminuyó en alrededorde un 50% por lo que la reincorporación a las actividades cotidia-nas fue más temprana (alrededor de la mitad del tiempo que enla cirugía convencional). Conclusión: La tecnología láser es unprocedimiento seguro que puede ser aplicado en el tratamiento dela enfermedad hemorroidal. El tiempo de cicatrización y de rein-corporación a las actividades cotidianas del paciente se reduceprácticamente a la mitad cuando se compara con otros estudiosde hemorroidectomía convencional. La aplicación de tecnologíaláser debe ser realizada por especialistas con dominio del equipoe instrumental(AU)


Objective: To present the application of laser technology in thetreatment of hemorrhoids diseae. A study performed in a privatecenter and at Coloproctology Unit of Hospital Universitario deCaracas. Methods:In a period between June 2012 and August2013, a total of 35 patients were studied with hemorrhoidal pro-blems all surgical criteria (bleeding, prolapse, pain). Of the patients,7 patients were treated as emergency cases and 28 cases wereelective. The equipment used was a laser diode 30W candle brandand on one occasion a team of DEKA laser CO2 was used.Patients were previously reported on the use of laser instrumentswhich passed. We evaluated operative time, intraoperative and pos-toperative bleeding, postoperative pain, healing time and return todaily activities. Results: Postoperative pain was observed in a valueof 4-6 points (base in analogue pain scale 1 to 10) which decre-ased after the first week postoperatively. The intraoperative blee-ding decreased around 80 %. Healing time decreased by about 50% so the return to daily activities was more early (about half thetime than conventional surgery). Conclusion: Laser technology isa safe procedure that can be applied in the treatment of hemor-rhoidal disease. The healing time and return to daily activities ofthe patient is reduced to almost half when compared with otherstudies of conventional hemorrhoidectomy. The application oflaser technology must be performed by domain specialists withequipment and instruments(AU)

RESUMO

BACKGROUND: Defecography is the gold standard for assessing functional anorectal disorders but is limited by the need for a specific radiologic environment, exposure of patients to radiation, and inability to show all anatomic structures involved in defecation. Echodefecography is a 3-dimensional dynamic ultrasound technique developed to overcome these limitations. OBJECTIVE: This study was designed to validate the effectiveness of echodefecography compared with defecography in the assessment of anorectal dysfunctions related to obstructed defecation. DESIGN: Multicenter, prospective observational study. PATIENTS: Women with symptoms of obstructed defecation. SETTING: Six centers for colorectal surgery (3 in Brazil, 1 in Texas, 1 in Florida, and 1 in Venezuela). INTERVENTIONS: Defecography was performed after inserting 150 mL of barium paste in the rectum. Echodefecography was performed with a 2050 endoprobe through 3 automatic scans. MAIN OUTCOME MEASURES: The κ statistic was used to assess agreement between echodefecography and defecography in the evaluation of rectocele, intussusception, anismus, and grade III enterocele. RESULTS: Eighty-six women were evaluated: median Wexner constipation score, 13.4 (range, 6-23); median age, 53.4 (range, 26-77) years. Rectocele was identified with substantial agreement between the 2 methods (defecography, 80 patients; echodefecography, 76 patients; κ = 0.61; 95% CI = 0.48-0.73). The 2 techniques demonstrated identical findings in 6 patients without rectocele, and in 9 patients with grade I, 29 with grade II, and 19 patients with grade III rectoceles. Defecography identified rectal intussusception in 42 patients, with echodefecography identifying 37 of these cases, plus 4 additional cases, yielding substantial agreement (κ = 0.79; 95% CI = 0.57-1.0). Intussusception was associated with rectocele in 28 patients for both methods (κ = 0.62; 95% CI = 0.41-0.83). There was substantial agreement for anismus (κ = 0.61; 95% CI = 0.40-0.81) and for rectocele combined with anismus (κ = 0.61; 95% CI = 0.40-0.82). Agreement for grade III enterocele was classified as almost perfect (κ = 0.87; 95% CI = 0.66-1.0). LIMITATIONS: Echodefecography had limited use in identification of grade I and II enteroceles because of the type of probe used. CONCLUSIONS: Echodefecography may be used to assess patients with obstructed defecation, as it is able to detect the same anorectal dysfunctions found by defecography. It is minimally invasive and well tolerated, avoids exposure to radiation, and clearly demonstrates all the anatomic structures involved in defecation.
