BackgroundThe 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.AimTo 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.
MethodsWere evaluated retrospectively 40 charts, 23 esophagectomies and 17 mucosectomies.
In assessing postoperative results, interviews were conducted by using a specific
questionnaire.ResultsComparing 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); 3) total time of hospitalization -
24.25 days and 20.76 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); 6) the presence of postoperative
complications - 65% and 35% (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).ConclusionsEsophageal 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.
