Postoperative 30-day mortality may underestimate the risk of esophagectomy / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the mortality of esophagectomy in our series and compare the different mortalities based on 30-day deaths and 90-day deaths postoperatively.</p><p><b>METHODS</b>A total of 954 patients undergoing esophagectomy by single-surgeon-team between January 2000 and December 2012 from our prospective database were enrolled. The mortalities based on 30-day and 90-day deaths postoperatively were compared, and the causes of deaths within 30 days and 90 days were analyzed.</p><p><b>RESULTS</b>Among all these 954 patients, a total of 20 postoperative deaths(2.1%) were observed: 11 within 30 days(1.1%) and 9 between 30 and 90 days after surgery(1.0%). The reasons for deaths within 30 days were as follows: 3 for respiratory failure related to anastomotic leakage,1 for bleeding after stenting due to anastomotic fistula, 1 for sepsis, 3 for respiratory failure from presenting preoperative respiratory morbidities, 2 for cardiac arrest caused by preoperative heart disorder, and 1 for multiple organ failure caused by early adjuvant chemotoxicity. The reasons for deaths between 30 and 90 days were as follows: 1 for respiratory failure related to anastomotic leakage, 1 for cardiac arrest from preoperative heart disorder, 1 for cerebrovascular accident, 1 for liver failure from liver cirrhosis presenting preoperatively, 1 for renal failure after operation, 1 for tumor progression and 2 for unknown reasons.</p><p><b>CONCLUSION</b>Since postoperative mortality calculated based on 30 days deaths postoperatively may underestimate the risk of esophagectomy, mortality calculated based on 90 days may be a better option.</p>
