This week my 17 year old son was diagnosed with perianal chrohns. He started getting ill a couple of weeks before his 17th birthday. He has lost over 2 stone in weight, had a perianal abscess drained a fistula in the sphincter which is now being drained by a seton band. He has had his life turned upside down, A levels cancelled etc. He has more procedures to go endoscopy and flexible Sigmoidoscopy. His uvula is covered in ulcers and subsequently down his throat. He started steriods yesterday and other stuff later on. I have had ulcerative colitis for 34 years but am in remission. Thank goodness he has myself and my husband to move and clean the seton band. He has been bleeding a bit from the scar tissue of abscess where seton band has entered the rectum and wasn't sure last night if a bit of faeces came out also. Does anyone have one of these his exits the anus and is a loose rubber band with stitches tied on. Any advice would be appreciated. We haven't been given length of time this will be in. He's just over 2 weeks post op.
