Injection of freshly collected adipose tissue for the treatment complex cryptoglandular anal fistula: case report

Introduction: Perianal fistula is a common colorectal disease which is caused mainly by cryptoglandular disease. Although most cases are treated successfully by surgery, management of complex perianal fistulas (CPAF) remains a challenge with limited results in recurrence and sometimes associated with fecal incontinence. The CPAF treatment with autologous adipose-derived mesenchymal stem cells (ASCs) had become a research hotspot. The technique started to be used in the treatment of Crohn's disease (CD) fistulas, where the studies showed safe and goods result from the procedure. Cultured ASCs have been used but this approach requires the preceding collection of adipose tissue, time for isolation of ASCs and subsequent in vitro expansion, need for laboratory facilities, and expertise in cell culturing. These factors have been getting over by using the commercially available alternative, allogenic ASCs. Treatment with allogeneic ASCs has shown good results in patients with CD fistulas, however with the disadvantage of being expensive. Objective: To show that the injection with freshly collected adipose tissue is an alternative to treatment with autologous or allogenic ASCs with several advantages. Methods: In this case report, we show our first experience in the treatment of CPAF with the application of collected adipose tissue in a tertiary referral hospital from Belo Horizonte, Brazil. Results The patient had a good postoperative recuperation with a complete fistula healing after 8 months without adverse effects. Conclusion: Injection with freshly collected adipose tissue is a promising and apparently safe sphincter-sparing technique in the treatment of CPAF. (AU)

Resultados do registro de cirurgias colorretais videolaparoscópicas realizadas no estado de Minas Gerais - Brasil de 1996 a 2009 / Colorectal laparoscopic surgeries performed in the state of Minas Gerais - Brasil from 1996 to 2009

INTRODUÇÃO: A partir de 1991, a videolaparoscopia começou a ser considerada no tratamento de doenças colorretais. O aprimoramento da técnica cirúrgica associado aos benefícios encontrados em diversos estudos publicados levou a modificações nas perspectivas da videolaparoscopia. A partir da publicação do estudo COST as ressecções oncológicas laparoscópicas foram reconhecidas como alternativa viável, com resultados semelhantes à cirurgia convencional. PACIENTES E MÉTODOS: Realizou-se pesquisa através de formulário específico e consulta a prontuários dos principais serviços de coloproctologia de Belo Horizonte. Avaliando-se sexo, idade, indicação cirúrgica, procedimento realizado, técnica laparoscópica, complicações, conversão, estadiamento e recidiva (no caso de neoplasias). RESULTADOS: Foram levantados dados sobre 503 cirurgias colorretais laparoscópicas: 347 (68,9 por cento) em mulheres e 156 (31,1 por cento) homens. A técnica cirúrgica foi totalmente laparoscópica em 137 casos, vídeo-assistida 245 casos. O procedimento mais realizado foi a retossigmoidectomia (41,1 por cento), seguido pela colectomia direita (12,5 por cento), colectomia esquerda (6,9 por cento). Doenças benignas foram responsáveis por 259 (51,5 por cento) casos, destes as principais indicações cirúrgicas foram endometriose 126 (48,6 por cento), pólipos 40 (15,4 por cento), doença diverticular 30 (11,6 por cento). Das 240 cirurgias realizadas por doenças malignas as mais frequentes foram retossigmoidectomia 102 (42,5 por cento), colectomia direita 46 (19,1 por cento), colectomia esquerda 18 (7,5 por cento), amputação abdominoperineal 18 (7,5 por cento). Houve 54 conversões (10.7 por cento) dos casos, 12,9 por cento (31/240) nos casos de neoplasias, 8,5 por cento (22/259) nos de doenças benignas. Complicações sistêmicas ou cirúrgicas ocorreram em 31 (6,1 por cento) e 56 (11,1 por cento) casos, respectivamente. Foram registrados onze (2,18 por cento) óbitos nos primeiros...

INTRODUCTION: Since 1991, laparoscopic surgery started to be considered in the treatment of colorectal disease. With the improvement of the technique and the confirmation of the benefits shown in several studies, the perspective of laparoscopy has changed. Recently, the oncologic resections were recognized as a viable alternative, with similar results to the conventional technique. PATIENTS AND METHODS: Data were collected based on charter review and a specific form from the coloproctology reference centers in Minas Gerais. The data assessed were age, gender, indication for surgery, the procedure performed, the laparoscopic technique, complications, conversion rate and staging (in case of tumor). RESULTS: Data from 503 surgeries were analyzed: 347 (68.9 percent) were women, and 156 (31.1 percent) men. The technique was totally laparoscopic in 137 cases, laparoscopically-assisted in 245. The procedure most frequently performed was rectosigmoidectomy (41.1 percent), followed by right hemicolectomy (12.5 percent) and left hemicolectomy (6.9 percent). Conversion occurred in 10.7 percent (54) cases, being 12.9 percent (31/240) in cases of neoplasia and 8.5 percent (22/259) in benign diseases. Systemic or surgical complications occurred in 31 (6.1 percent) and 56 (11.1 percent) cases, respectively. The surgical mortality was 2.18 percent (11). Benign diseases were responsible for 259 (51.5 percent) cases, the most frequent indications were endometriosis 126 (48.6 percent), polyps 40 (15.4 percent) and diverticular disease 30 (11.6 percent) cases. From the 240 surgeries performed for malignant disease, the most frequent were rectosigmoidectomy 102 (42.5 percent), right hemicolectomy 46 (19.1 percent), left hemicolectomy 18 (7.5 percent) and abdominoperineal resection 18 (7.5 percent). CONCLUSION: This study was the first survey about the implementation of laparoscopic colorectal surgery done in Minas Gerais. The data are consistent with the...

Sindrome de currarino associada ao Tailgut Cyst: ressecção abdômino-sacral / The Tailgut Cyst is na embryological remnant of the retrorectal (Presacral) space that can be a part of the currarino syndrome

O Tailgut Cyst é um remanescente embriológico do intestino posterior, que pode fazer parte da Síndrome de Currarino. Relato do caso: Paciente feminino, 43 anos com lombalgia, retenção urinária e massa retrorretal. História pregressa de ânus ectópico, constipação associada a megacólon congênito. Exames de imagem evidenciando cisto retrorretal comprimindo o sacro, rechaçando as estruturas pélvicas anteriormente e deformidade sacral congênita. Realizada ressecção em bloco da lesão retrorretal, reto, útero e sacro ao nível de S2. Anátomo-patológico evidenciando tailgut cyst. Caracterizamos a paciente como portadora de síndrome de Currarino. Discusão: A síndrome de Currarino é caracterizada pela malformação anorretal, defeito sacral e massa retrorretal. Tem relação com a mutação do gene HLXB9. O tailgut cyst é um remanescente embriológico do intestino posterior, mais comum em mulher adulto jovem (75-90 por cento). O tailgut cyst relacionado à Síndrome de Currarino é uma lesão incomum. A maioria dos pacientes é assintomática, mas podem apresentar sintomas anorretais, perineais e sacrais. Exames de imagem são úteis para a definição diagnóstica e programação cirúrgica. A excisão cirúrgica completa é recomendada devido ao risco de recorrência, degeneração maligna e infecção crônica, mesmo em pacientes assintomáticos. O prognóstico é incerto.

The Tailgut Cyst is an embryological remnant of the hindgut that can be a part of the Currarino Syndrome. Report of a case: A 43-year-old woman with lombalgy, urine retain and presacral mass. Preceding history of ectopic anus, constipation associated with congenital megacolon. Imaging exams indicate retrorectal cyst that compresses the sacral region, receding the pelvic structure forward and congenital sacral deformity. A block resection of the retrorectal, rectal, uterus and sacrum lesion was carried out in a S2 level. Anatomo-pathologic indicate tailgut cyst. The patient is characterized as carrying the Currarino Syndrome. Discussion: The syndrome is characterized by the malformation of the anorectal, sacral abnormalties and retrorectal mass. It has connection with a gene mutation of the HLXB9. The Tailgut Cyst is an embryological remnant of the hindgut, more common in young adult women (75-90 percent). The tailgut cyst related to the Currarino Syndrome is an uncommom lesion. Most patients are asymptomatic, however, they may present anorectal, perineo and sacrum symptoms. Imaging exams are useful for diagnostic definition and surgery programming. The complete surgery excision is recommended due to the risk of reestablishment, malignant degeneration and chronic infection, even in asymptomatic patients. The prognosis is uncertain.
