Leaks have occurred years out. "Diagnosis of a gastric leak can be difficult, as the presentation can vary from asymptomatic to severe septic shock." "The cause of a gastric leak is indicative of some abnormality or failure of normal healing process of tissue. There is a general agreement that local risk factors contributing to a leak are impaired suture line healing due to staple dehiscence, poor blood flow, and infection. These risk factors contribute to decrease in oxygen and subsequent ischemia to the tissue" "...leaks after LSG procedures can be a very serious, life-threatening complication that needs immediate attention. Currently, the literature has yet to define an absolute algorithm as to how to manage and treat gastric leaks; however, there is a consensus that timing of diagnosis, severity, and location all play a role in constructing a treatment plan." www.hindawi.com/journals/crigm/2013/136153/
