Esophageal mucosal resection versus esophagectomy: a comparative study of surgical results in patients with advanced megaesophagus

The surgical treatment of advanced megaesophagus has no consensus, being esophagectomy the more commonly used method. Since it has high morbimortality--inconvenient for benign disease -, in recent years an alternative has been introduced: the esophageal mucosal resection. To compare early and late results of the two techniques evaluating the operative time, length of ICU stay; postoperative hospitalization; total hospitalization; intra- and postoperative complication rates; mortality; and long-term results. Were evaluated retrospectively 40 charts, 23 esophagectomies and 17 mucosectomies. In assessing postoperative results, interviews were conducted by using a specific questionnaire. Comparing the means of esophagectomy and mucosal resection, respectively, the data were: 1) surgical time--310.2 min and 279.7 min (p > 0.05); 2) length of stay in ICU--5 days and 2.53 days (p 0.05); 4) length of hospital stay after surgery--19.05 days and 14.94 days (p> 0.05); 5) presence of intraoperative complications--65% and 18% (p 0.05). In the assessment of late postoperative score (range 0-10) esophagectomy (n = 5) obtained 8.8 points and 8.8 points also got mucosal resection (n = 5). Esophageal mucosal resection proved to be good alternative for surgical treatment of megaesophagus. It was advantageous in the immediate postoperative period by presenting a lower average time in operation, the total hospitalization, ICU staying and complications rate. In the late postoperative period, the result was excellent and good in both operations.The surgical treatment of advanced megaesophagus has no consensus, being esophagectomy the more commonly used method.

COMPORTAMENTO HIDROLÓGICO DE ENCOSTA EM SUBSTRATO ROCHOSO GRANÍTICO SOB INFLUÊNCIA DE DESLIZAMENTO RASO - NOVA FRIBURGO, RIO DE JANEIRO

Tendo a água como principal agente deflagrador dos deslizamentos em regiões tropicais, este trabalho objetivou o estudo hidrológico de uma encosta com um cicatriz de deslizamento do tipo translacional raso, no evento extremo de chuva de Janeiro de 2011, Nova Friburgo-RJ. Para o entendimento da influência da água subterrânea na deflagração dos movimentos de massa, a área foi sondada e instrumenta, visando a caracterização física da encosta
