Abstract:
Fistulization of pancreatic pseudocysts into surrounding viscera is a well-known phenomenon and usually requires surgical management. We report two cases of pancreatic pseudocysts that developed spontaneous fistulas to the colon with resulting fever and abdominal pain. The patients were managed nonoperatively with a combination of endoscopic drainage and antibiotics, and their pseudocysts and fistulas resolved. The patients have remained symptom-free for a mean of 14 months of follow-up.
