Insuficiencia intestinal secundaria a síndrome de intestino corto: resultados de un programa multidisciplinario de rehabilitación intestinal / Intestinal failure due to short bowel syndrome: impact of a multidisciplinary intestinal rehabilitation program

Background: In patients suffering intestinal failure due to short bowel, the goal of an Intestinal Rehabilitation Program is to optimize and tailor all aspects of clinical management, and eventually, wean patients off lifelong parenteral nutrition. Aim: To report the results of our program in patients suffering intestinal failure. Patients and Methods: A registry of all patients referred to the Intestinal Failure unit between January 2009 and December 2015 was constructed. Initial work up included prior intestinal surgery, blood tests, endoscopic and imaging studies. Also demographic data, medical and surgical management as well as clinical follow-up, were registered. Results: Data from 14 consecutive patients aged 26 to 84 years (13 women) was reviewed. Mean length of remnant small bowel was 100 cm and they were on parenteral nutrition for a median of eight months. Seven of 14 patients had short bowel secondary to mesenteric vascular events (embolism/thrombosis). Medical management and autologous reconstruction of the bowel included jejuno-colic anastomosis in six, enterorraphies in three, entero-rectal anastomosis in two, lengthening procedures in two, ileo-colic anastomosis in one and reversal Roux-Y gastric bypass in one. Thirteen of 14 patients were weaned off parenteral nutrition. Conclusions: Our Multidisciplinary Intestinal Rehabilitation Program, allowed weaning most of the studied patients off parenteral nutrition.

Treatment of short bowel syndrome in children. Value of the Intestinal Rehabilitation Program / Tratamento da síndrome do intestino encurtado na criança: valor do Programa de Reabilitação Intestinal

Summary The main cause of acute intestinal failure is short bowel syndrome, generally as a result of resection of extensive segments of small intestine. As a result, the main symptoms are watery diarrhea, malabsorption syndrome, chronic malnutrition, and death, if the patient is not properly treated. If the length of the remaining intestine is greater than 30 cm, complete adaptation is possible and the patient may not require parenteral nutrition. The currently recommended treatment includes the use of prolonged parenteral nutrition and enteral nutrition, always aimed at constant weight gain, in conjunction with surgeries aimed at elongating the dilated bowel. This set of procedures constitutes what is called an Intestinal Rehabilitation Program. This therapy was used in 16 children in periods ranging from 8 months to 7.5 years, with survival in 75% of the cases. Finally, the last resort to be used in children with complete resection of the small bowel is an intestinal transplant. However, to date there is no record of a Brazilian child that has survived this procedure, despite it being attempted in seven patients. We conclude that the results of the intestinal rehabilitation program are encouraging for the continuation of this type of treatment and stimulate the creation of the program in other pediatric care institutions.

Resumo A principal causa da falência intestinal aguda é a síndrome do intestino encurtado, decorrente, em geral, de ressecção de extensos segmentos de intestino delgado. Em consequência, os principais sintomas são diarreia aquosa, síndrome de má absorção, desnutrição crônica e óbito, caso o paciente não seja adequadamente tratado. Se o comprimento do intestino remanescente for superior a 30 cm, poderá haver adaptação completa e o paciente poderá ficar livre da nutrição parenteral. O tratamento atualmente preconizado inclui a utilização de nutrição parenteral prolongada e de nutrição enteral, objetivando sempre o ganho ponderal constante, em paralelo a cirurgias que visem ao alongamento do intestino dilatado. Esse conjunto de procedimentos constitui o que se denomina Programa de Reabilitação Intestinal. Essa terapia foi utilizada em 16 crianças, em períodos que variaram de 8 meses a 7 anos e meio, com sobrevida em 75% dos casos. O último recurso utilizado em crianças com ressecção completa do intestino delgado é o transplante intestinal. Até o momento, não há registro de criança brasileira que tenha sobrevivido a esse procedimento, a despeito de sete pacientes terem sido submetidos a ele. Os resultados do Programa de Reabilitação Intestinal nos anima a continuar com esse tipo de tratamento e estimular a criação do programa em outras instituições de atendimento pediátrico.
