I lost most of last year to a Whipple procedure for Ampullary cancer. Painful and debilitating. Submitting to more surgery when the surgeon himself has no faith that it would be successful is unnecessary risk for uncertain gain. My oldest son had 4 open heart surgeries, 2 artificial valves, a pig patch and a pacemaker, so I’ve seen the consequences first hand.
Whatever is in your future I wish you the best, medical issues like that are difficult situations to deal with
