Fecal incontinence is a disabling condition for which the long-term traditional operative methods have been disappointing. During the last 2 decades, sacral neuromodulation has emerged as the preferred first-line surgical option for many patients with debilitating fecal incontinence. This program will focus on the rationale for and results of sacral neuromodulation for fecal incontinence. The world-renowned faculty will explain the mechanisms of action, discuss patient selection, and demonstrate the surgical technique. The cutting-edge comprehensive content is of tremendous importance to all physicians and surgeons who evaluate and manage patients with fecal incontinence.

Minimally invasive surgery has been repeatedly proven to have many benefits. While laparoscopy, the original form of minimally invasive surgery, revolutionized abdominopelvic surgery, it has some potential limitations. During the last almost 35 years, minimally invasive technology has evolved to optimize outcomes. In addition, global access to safe cost-effective platforms is essential to make the benefits of minimally invasive surgery available to patients around the world. In this program, several internationally renowned experts discuss some potential limitations to laparoscopy and present some innovative technologies designed to further advance minimally invasive surgery.
