enterovesical fistula
communication between bowel and bladder
enterovesical fistula symptoms
bubbly urine, recurrent UTIs
enterovesical fistula - think!
CRC
enterocutaneous fistula
between the intestines + the skin, high (duodenal/jejunal) vs low (colo) output
enteroenteric/enterocolic/enterovaginal fistula
involving the large/small intestine/vagina
dupdenal/jejunalcutaneous fistula
tend to be high output, electrolyte rich, leading to skin excoriation
colocutaneous fistula
tend to be low output, faeculent material,
enterocutaneous fistula may result from a
spontaneous rupture of an abscess, or iatrogenic
the problem with enteroenteric/enterocolic/enterovaginal fistula
bacterial overgrowth may precipitate malabsorption Ss which is particularly serious in IBD
octreotide
reduces pancreatic secretions
reduces pancreatic secretions
octrecotide
fistula management
will heal on their own if no pathology + if left, fit a stoma bag, TPN if causing nutritional deficiency
