My mother had undergone infraumblical ventral hernia surgery (mesh repair) before 10days. But after surgery there is watery thin discharge from surgical site ( doctor didn't closed one stitch and remain open for fluid drainage) our doctor said it's fatty Serous fluid discharge but we are worried for how many days it will come because it's approx 50-60ml of discharge from that drain hole) Doing alternate days dressing . No fever. How many days required to stop Serous discharge in normal scenario?? Please reply. Thank you!
