Short-term Outcomes of Emergent Versus Elective Gastrectomy for Gastric Adenocarcinoma: A National Surgical Quality Improvement Program Study.

Background: Gastric adenocarcinoma is a leading cause of cancer death worldwide and in the United States, and can present emergently with upper GI hemorrhage, obstruction, or perforation. Few large studies have examined how emergency surgery for gastric cancer affects patient outcomes.

Methods: All patients from National Surgical Quality Improvement Program with gastric adenocarcinoma from 2005 to 2017 were examined retrospectively. Univariate and multivariate analysis of patient factors and perioperative outcomes was performed. -values < .05 were significant.

Results: Of 4663 total patients, 115 had emergency surgery and 4548 had elective surgery. Emergency surgery patients were more likely to be non-white, underweight, higher ASA class, require a preoperative blood transfusion, and were less likely to be functionally independent. Multivariate analysis demonstrates an increased likelihood of unplanned intubation, prolonged ventilation, and deep vein thrombosis (DVT).

Discussion: There are no significant differences in mortality, reoperation, or infection when comparing emergent surgery for gastric cancer and elective surgery; however, there is an increased risk of reintubation, prolonged intubation, and DVT in patients undergoing emergent surgery. Patients requiring emergent surgery have more comorbidities, higher blood transfusion requirements, and worse preoperative functional status, and this study demonstrates that they also have worse perioperative outcomes. Previous studies have shown that long-term oncologic outcomes are worse for patients undergoing urgent surgery, and this study shows that perioperative outcomes are also somewhat worse. Thus, definitive surgery performed on a patient who presents emergently with gastric cancer should be considered but may come at the cost of increased perioperative respiratory complications, DVTs, and worse oncologic outcomes.
