Background:Open and laparoscopic trans-hiatal esophagectomy has been successfully performed in the treatment of megaesophagus. However, there are no randomized studies to differentiate them in their results. Aim:To compare the results of minimally invasive laparoscopic esophagectomy (EMIL) vs. open trans-hiatal esophagectomy (ETHA) in advanced megaesophagus. Method:A total of 30 patients were randomized, 15 of them in each group - EMIL and ETHA. The studied variables were dysphagia score before and after the operation at 24-months follow-up; pain score in the immediate postoperative period and at hospital discharge; complications of the procedure, comparing each group. Were also studied: surgical time in minutes, transfusion of blood products, length of hospital stay, mortality and follow-up time. Results:ETHA group comprised eight men and seven women; in the EMIL group, four women and 11 men. The median age in the ETHA group was 47.2 (29-68) years, and in the EMIL group of 44.13 (20-67) years. Mean follow-up time was 33 months, with one death in each group, both by fatal aspiration. There was no statistically significant difference between the EMIL vs. ETHA scores for dysphagia, pain and in-hospital complications. The same was true for surgical time, transfusion of blood products and hospital stay. Conclusion:There was no difference between EMIL and ETHA in all the studied variables, thus allowing them to be considered equivalent.
OBJETIVO: Avaliar os resultados da esofagectomia trans-hiatal no tratamento do megaesôfago chagásico avançado. MÉTODO: Foram estudados retrospectivamente 28 pacientes portadores de megaesôfago chagásico avançado (MCA), graus III e IV, segundo a classificação radiológica de Rezende (adotada pela Organização Mundial de Saúde), e que foram submetidos à esofagectomia subtotal trans-hiatal no Serviço de Clínica Cirúrgica do Hospital Universitário Prof. Alberto Antunes (HUPAA) da Universidade Federal de Alagoas, entre 1982 e 2000. Foram analisadas, as seguintes variáveis: A) Queixas clínicas pré-operatórias versus as pós-operatórias (disfagia, regurgitação, pirose, diarréia, dumping, plenitude pós-prandial, pneumonia e o estado ponderal). B) avaliação radiológica pós-operatória da boca anastomótica esofagogástrica cervical e do estômago transposto. C) avaliação endoscópica pós-operatória do coto esofágico e da boca anastomótica. RESULTADOS: O seguimento variou de 4 a 192 meses, média de 58,18 meses. Dezesseis pacientes eram do sexo feminino e 12 masculinos. Idade mínima de 16 e máxima de 67 anos, média de 36,5 anos. Não houve mortalidade nesta série. Houve resolução plena da disfagia na maioria dos pacientes (20/28 - 71,4%), um (3,6%) referiu disfagia leve que não necessitou tratamento e 7/28 (25%) necessitaram de uma ou mais sessões de dilatação. Nenhum necessitou de dilatação permanente. A pirose foi o sintoma mais importante no seguimento tardio (35,7%), seguida da regurgitação (25%), diarréia (14,3%), plenitude pós-prandial (10,7%) e dumping (3,6%). Houve ganho ponderal em 87,5% dos pacientes avaliados. A esofagite no coto esofágico foi o achado endoscópico mais significativo (46,4%). O esôfago de Barrett no coto remanescente foi encontrada em 10,7% dos casos. A maioria dos achados radiológicos foi normal, embora três doentes (10,7%) tenham apresentado estase gástrica. CONCLUSÃO: A esofagectomia trans-hiatal mostrou-se eficaz para o tratamento da disfagia no megaesôfago chagásico avançado, embora com morbidade elevada, porém com mortalidade nula.
Among the challenges of esophagectomies, the cervical anastomosis remains challenging for its consequences, the main being the anastomotic stricture. The authors present a technique for an Orringer-fashion mechanical cervical laterolateral esophagogastric anastomosis, which reduces the rate of fistula and stenosis.
