Background: There is no advantage in maintaining patients on oral fasting after gastrointestinal elective resection. The early feeding up to 48 h can be beneficial, because it reduces infectious complications and hospital stay. Aim: Evaluate the evolution and tolerance of early oral diet in postoperative period after gastrectomy for gastric cancer. Methods: Anthropometric assessment was performed on the day of surgery, weight, height, body mass index and weight loss were measured. Acceptance of diet was evaluated as food intake (amount accepted) and gastrointestinal symptoms such as nausea, vomiting, constipation, diarrhea, abdominal distension, postoperative complications and hospital stay. Results: The sample consisted of 23 patients, 17 with partial gastrectomy and six with total gastrectomy. In the assessment of nutritional status 9% were malnourished, 54.5% normal weight, 9% overweight and 27.2% obese, but 54% had weight loss. There was good acceptance of the diet in 96,9% of the sample. Nausea and abdominal distension were present in 4,3% and 65.2% constipation. Surgical complications according to the Clavien scalle, 13% had grade V, 4.3% grade IIIA, 8.7% grade I and 73% did not have complications. The length of hospital stay was 5±2.2 days. Conclusion: Early postoperative re-feeding in total and partial gastrectomy was well tolerated by patients.

ResumoOs linfomas são uma neoplasia maligna, os quais se originam nos linfonodos, que estão envolvidos no combate às infecções. Essa neoplasia teve o maior crescimento na incidência entre as doenças oncohematológicas. O objetivo do estudo foi avaliar os possíveis sintomas gastrointestinais apresentados pelo paciente durante o tratamento e relacioná-los com a ingestão alimentar e estado nutricional. Foi realizada a avaliação subjetiva global, índice de massa corporal, área muscular do braço e avaliada o consumo alimentar, assim como presença de sintomas gastrointestinais em portadores de linfoma, submetidos à quimioterapia ambulatorial. A amostra foi composta por 30 pacientes do Serviço de Oncologia Clínica do Hospital Erasto Gaertner do Paraná, entre os meses de maio a junho de 2014, sendo 33,3% com linfoma de Hodgkin e 66,7% com linfoma não Hodgkin. Segundo a ASG 100% dos pacientes foram considerados como nutridos, porém 46,7% dos pacientes apresentaram perda ponderal. Segundo a AMB, 57% dos pacientes apresentaram algum grau de desnutrição. Em relação ao IMC, 26,7% dos adultos estavam eutróficos, 30% com sobrepeso, 13,3% obesidade e nenhum com desnutrição, já nos idosos 6,7% estavam abaixo do peso, 6,7% eutróficos e 16,7% com excesso de peso. Houve diminuição na ingestão alimentar por parte dos pacientes após início da quimioterapia, sendo náuseas, disgeusia, xerostomia e obstipação os sintomas mais frequentes. Considerando os sintomas gastrointestinais que interferem diretamente no padrão alimentar e a perda ponderal ocasionados pelo tratamento quimioterápico, os pacientes oncohematológicos devem ser considerados pacientes em risco nutricional e receber acompanhamento nutricional especializado, visando minimizar seus efeitos colaterais adversos e melhorar sua qualidade de vida.Palavras chave: Linfoma.

This cancer had the highest increase in incidence among oncohematological diseases. The objective of the study was evaluate the possible gastrointestinal symptoms presented by the patient during treatment and relates them to food intake and nutritional status. The subjective global assessment was performed; body mass index, arm muscle area and assessed food intake, as well as presence of gastrointestinal symptoms in patients with lymphoma undergoing outpatient chemotherapy. The sample consisted of 30 patients of the Oncology Clinic Erasto Gaertner Hospital of Paraná service, between the months of May and June 2014, 33.3% with Hodgkin's lymphoma and 66.7% with non-Hodgkin lymphoma. According to ASG 100% of patients were considered nourished, but 46.7% of patients had weight loss. According to the AMB, 57% of patients had some degree of malnutrition. In the BMI, 26.7% of adults were eutrophic, 30% were overweight, 13.3% were obese and none with malnutrition, in relation to the elderly 6.7% were underweight, 6.7% were eutrophic and 16.7 % overweight. There was a decrease in f...
