Like any surgical procedure, complications can happen like leaks, bleeding, hernias, and chronic heartburn. Preparation is key to a successful outcome, and we will be holding your hand all the way. Our complication rate is one of the lowest published in the literature. In fact, our leak rate is 0%, and with the implementation of the new techniques designed at OCC, our patients are experiencing substantial and permanent weight loss without the undesirable symptom of heartburn.
