Acerto Project - 15 years changing perioperative care in Brazil / Projeto Acerto - 15 anos modificando cuidados perioperatórios no Brasil

ABSTRACT The ACERTO project is a multimodal perioperative care protocol. Implemented in 2005, the project in the last 15 years has disseminated the idea of a modern perioperative care protocol, based on evidence and with interdisciplinary team work. Dozens of published studies, using the protocol, have shown benefits such as reduced hospital stay, postoperative complications and hospital costs. Disseminated in Brazil, the project is supported by the Brazilian College of Surgeons and the Brazilian Society of Parenteral and Enteral Nutrition, among others. This article compiles publications by the authors who belong to the CNPq research group "Acerto em Nutrição e Cirurgia", refers to the experience of other national authors in various surgical specialties, and finally outlines the evolution of the ACERTO project in the timeline.

RESUMO O projeto ACERTO é um protocolo multimodal de cuidados perioperatórios. Implementado em 2005, o projeto, nos últimos 15 anos, tem disseminado a ideia de moderno protocolo de cuidados perioperatórios baseados em evidência e com atuação interprofissional. Dezenas de estudos publicados com o uso do protocolo têm mostrado benefícios como redução do tempo de internação, complicações pós-operatórias e custos hospitalares. Disseminado pelo Brasil, o projeto tem apoio do Colégio Brasileiro de Cirurgiões e da Sociedade Brasileira de Nutrição Parenteral e Enteral, entre outros. Este artigo compila publicações dos autores que compõem o grupo de pesquisa do CNPq "Acerto em Nutrição e Cirurgia", cita a experiência de outros autores nacionais em diversas especialidades cirúrgica e finalmente, delineia a evolução do projeto ACERTO ao longo da linha do tempo.

Cost-effectiveness of perioperative immunonutrition in gastrointestinal oncologic surgery: a systematic review / Custo-benefício da imunonutrição perioperatória em cirurgia oncológica do trato gastrointestinal: uma revisão sistemática

ABSTRACT Introduction: Costs, length of hospital staying and morbidity are frequently and significantly increased as a result of infections and other complications following surgical procedure for gastrointestinal tract cancer. Recently, improving host defence mechanisms have become a target of interest. Immunonutrition aims at improving immunity, most likely providing key nutrients to maintain T-lymphocyte and other host defence. Aim : To evaluate the immunonutrition in cancer patients who are operated by digestive diseases and assess the cost-effectiveness of this supplementation. Methods: This study consisted of a systematic review of the literature based on reference analyses retrieved from current databases such as PubMed, Lilacs and SciELO. The search strategy was defined by terms related to immunonutrition [immunonutrition, arginine, omega-3 and nucleotides] in combination with [costs, cost-effective and cost-effectiveness] as well as [gastrointestinal cancer surgery, oesophageal, gastric or pancreatic surgery] in English, Portuguese or Spanish language. For cost analyses, currencies used in the manuscripts were all converted to American dollars (US$) in order to uniform and facilitate comparison. Six prospective randomized studies were included in this review. Conclusion: The cost-effectiveness was positive in most of studies, demonstrating that this diet can significantly reduce hospital costs in the North hemisphere. However, similar studies needed to be carried to determine such results among us.

RESUMO Introdução: Custos, tempo de hospitalização e morbidade estão frequentemente aumentados na presença de infecções e outras complicações decorrentes de procedimentos cirúrgicos para o câncer gastrointestinal. Recentemente, a melhora de mecanismos de defesa do hospedeiro tem se tornado um alvo de interesse. Nutrição adequada está fortemente relacionada com competência imune e redução de infeções. Imunonutrição objetiva a melhora da imunidade, principalmente para manutenção de linfócitos-T e outras defesas. Objetivo : Avaliar a imunonutrição em pacientes oncológicos que são operados por doenças do aparelho digestivo e avaliar a relação custo-eficácia desta suplementação. Métodos: Revisão sistemática da literatura baseada nas bases de dados PubMed, Lilacs e SciELO. A busca foi realizada com combinação de descritores em inglês e português relacionados ao tema da revisão: [immunonutrition, arginine, omega-3, nucleotides] combinado com [costs, cost-effective, cost-effectiveness] e [gastrointestinal cancer surgery, oesophageal, gastric or pancreatic surgery]. Para análise de custos, moedas usadas nos artigos foram todas convertidas para dólar americano. Seis estudos randomizados prospectivos foram incluídos nesta revisão. Conclusão: O custo-benefício foi positivo na maioria dos estudos, sugerindo que este tipo de dieta reduz significativamente os custos hospitalares nos países do hemisfério norte. Contudo, estudos similares de custo-benefício devem ser realizados para definir o real custo-benefício em nosso meio.

Outcomes of flexible ureteroscopic lithotripsy with holmium laser for upper urinary tract calculi

OBJECTIVE: To assess the perioperative and financial outcomes of flexible ureteroscopic lithotripsy with holmium laser for upper tract calculi in 44 patients. MATERIALS AND METHODS: Between February 2004 and September 2006, 44 patients treated for upper tract stone with flexible ureteroscopic lithotripsy were evaluated. Renal stones were associated with collecting system obstruction in 15 (34 percent) patients, failed extracorporeal shock-wave lithotripsy (SWL) occurred in 14 (32 percent) patients, unilateral multiple stones in 18 (41 percent) patients, and multiple bilateral stones in 3 (7 percent). In 29 (66 percent) patients, the stone was located in the inferior calyx. Perioperative and financial outcomes were also evaluated. RESULTS: 50 procedures were performed in 44 patients. The mean stone burden on preoperative CT scan was 11.5 ± 5.8 mm. The mean operative time was 61.3 ± 29.4 min. The stone free rate was 93.1 percent after one procedure and 97.7 percent after a second procedure, with overall complication rate of 8 percent. Therapeutic success occurred in 92 percent and 93 percent of patients with lower pole stones and SWL failure, respectively. Treatment failure of a single session was associated with presence of a stone size larger than 15 mm (p = 0.007), but not associated with inferior calyx location (p = 0.09). Surgical disposables were responsible for 78 percent of overall costs. CONCLUSION: Flexible ureteroscopy using holmium laser is a safe and effective option for the treatment of upper urinary tract calculi. In addition, it can be considered an attractive option as salvage therapy after SWL failure or kidney calculi associated with ureteral stones. Stone size larger than 15 mm is associated with single session treatment failure.
