As is true of many innovations in medicine, a better idea often stems from the source, in this case the surgeon. Nasser Dib, MD, a prominent general/bariatric Polish surgeon in Warsaw, recognised the need for better visibility in complex abdominal surgical procedures. In MIS procedures the cavity is brightly lit.
Despite that and the best intentions there is always the possibility to cut what was not intended. By transilluminating the organ and thereby significantly improving visibility and awareness the surgeon can dramatically reduce the potential for unintended consequences. Dr. Dib created such a tool, the Gastric Light Guide, to transilluminate the GI tract from esophagus to pylorus.
