Background Previous studies have reported on the association between perioperative morbidity and diminished oncologic outcomes in patients undergoing resection for colorectal or pancreatic cancer. However, the effect of anastomotic leak (AL) on the survival of patients with gastric or esophageal cancer remains unclear. Methods Clinicopathologic data of patients who underwent resection for gastric or esophageal cancer between 2005 and 2012 were assessed, and predictors for overall survival and disease-free survival were identified. In addition, we evaluated the impact of AL on oncologic outcomes. Results Curative resection for gastric or esophageal cancer was performed in 471 patients. The primary tumor was located in the stomach and esophagus in 53% and 47% of the patients, respectively. Forty-one patients (8.7%) suffered an AL. The AL rate was significantly higher following resection for esophageal cancer compared with the resection for gastric cancer (12.9% vs 5.3%, P = .001). Postoperative mortality (4%) was not significantly associated with the occurrence of AL (4% without AL vs 7% with AL, P = .2). After a median follow-up time of 35 months, the median overall survival and disease-free survival were 101 and 93 months, respectively. Factors associated with worse overall survival in multivariate analysis included AL ( P = .001), American Society of Anesthesiologists physical status ( P < .0001), advanced Union for International Cancer Control (UICC) stage ( P < .0001), and poorly differentiated carcinoma (G3; P = .04). In the multivariate analysis for predictors of disease-free survival, AL ( P = .037), advanced UICC stage ( P < .0001), poorly differentiated carcinoma (G3; P = .044), and lymphangiosis carcinomatosa ( P = .004) were independently associated with a high risk for recurrence. Conclusion AL following resection for gastric and esophageal cancer has a negative prognostic impact on long-term survival, independent from tumor stage and biology. Further investigation of the interactions between AL and the development of tumor recurrence as well as the establishment of standardized perioperative care protocols are necessary for the improvement of outcomes after gastric and esophageal resection.

Background & Aims: Acute liver failure (ALF) is a severe form of acute liver injury that can progress to multiple organ failure. We investigated causes and outcomes of ALF. Methods: Eleven university medical centers in Germany were asked to report patients with (primary) severe acute liver injury (sALI) (international normalized ratio [INR] >1.5 but no hepatic encephalopathy) and primary ALF (INR >1.5 with overt hepatic encephalopathy) treated from 2008 to 2009. Data were analyzed from 46 patients with sALI and 109 patients with ALF. Results: The most frequent etiologies of primary ALF were non-acetaminophen drug-induced (32%), indeterminate (24%), and viral (21%); acetaminophen ingestion was the cause of ALF in only 9% of patients. The support of a ventilator was required by 44% of patients with ALF, vasopressors by 38%, and renal replacement by 36%. Seventy-nine patients with ALF (72%) survived until hospital discharge, 38 (35%) survived without emergency liver transplantation (ELT), and 51 received ELT (47%); 80% of patients who received ELT survived until discharge from the hospital. Conclusions: In Germany, drug toxicity, indeterminate etiology, and viral hepatitis appear to be the major causes of primary ALF, which has high mortality. Patients with ALF are at great risk of progressing to multiple organ failure, but 80% of patients who receive ELT survive until discharge from the hospital. [ABSTRACT FROM AUTHOR]
