To study the diagnostic specificity and sensitivity of various modalities used for the assessment of anastomotic leak in esophagogastric surgery and to identify the most sensitive technique. Secondarily, to propose a clinical algorithm to guide clinicians in the diagnosis of anastomotic leaks esophagogastric surgeries.

Anastomotic leak in esophagogastric surgery remains a diagnostic challenge despite advances in imaging techniques. All available modalities appear to have limited sensitivities and have significant false negatives. A high index of clinical suspicion continues to be the key element in the early diagnosis of esophagogastric anastomotic leaks. The incidence of anastomotic leak in esophagogastric surgeries is reported to range from 7-20% in various studies, and it is a major complication that increases hospital stay and mortality. It is important to identify these complications early to optimize the outcomes of these patients. There has been no study till date that examines the incidence of false negative results for anastomotic leak in esophagogastric surgeries. False negative findings may give surgeons a false sense of assurance in the patient's postoperative recovery, and escalation of oral intake may result in catastrophic complications and outcomes in these patients. This study seeks to identify the most sensitive modality in the diagnosis of esophagogastric anastomotic leaks in a retrospective series of patients.
