Name of journal: Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary TractAbstract: BACKGROUND: The relationship between individual complications and esophagectomy mortality is unclear. The influence of comorbidities on the impact of complications on operative mortality is also unknown.

The independent association of certain postoperative events with mortality is an objective method of terming a complication "major" and may aid efforts to reduce mortality.METHODS: All gastric conduit esophagectomies performed for cancer from 2008 to 2017 in the Society of Thoracic Surgery database were identified. Chi square was utilized to identify postoperative events associated with operative mortality. Multivariable logistic regression analysis was performed, utilizing postoperative events, to determine the risk-adjusted effect on operative mortality for each postoperative event.

BACKGROUND: The relationship between individual complications and esophagectomy mortality is unclear. The influence of comorbidities on the impact of complications on operative mortality is also unknown. We sought to assess the impact of individual complications and the effect of coexisting comorbidities on operative mortality following esophagectomy.

CONCLUSIONS: In the Society of Thoracic Surgery database, 64% of patients suffer postoperative events and 3.3% die following esophagectomy. The independent association of certain postoperative events with mortality is an objective method of terming a complication "major" and may aid efforts to reduce mortality.

METHODS: All gastric conduit esophagectomies performed for cancer from 2008 to 2017 in the Society of Thoracic Surgery database were identified. Chi square was utilized to identify postoperative events associated with operative mortality. Multivariable logistic regression analysis was performed, utilizing postoperative events, to determine the risk-adjusted effect on operative mortality for each postoperative event. To assess the effect of preoperative comorbidities, a second logistic regression analysis was performed, incorporating preoperative characteristics.

RESULTS: Of 11,943 esophagectomy patients, 63.9% had a postoperative event and 3.3% died, which did not change over the study period. The postoperative events with the highest impact on operative mortality were respiratory distress syndrome (OR 7.48 (95% CI 5.23-10.7)), reintubation (OR 6.55 (4.61-9.30)), and renal failure (OR 5.97 (4.08-8.75)). Anastomotic leak requiring reoperation was associated with increased operative mortality (OR 1.48 (1.03-2.14)), but medically managed leak was not. Incorporating preoperative characteristics into the operative mortality model had little effect on odds ratio for death for individual postoperative events.
