Abstract：
BACKGROUND: Despite pancreatic extracorporeal shock wave lithotripsy (P-ESWL) is a minimally invasive treatment for pancreatic stones, complications exist.
METHODS: A 37-year-old male was diagnosed with chronic pancreatitis and admitted to our hospital for recurrent acute pancreatitis. After the first P-ESWL session, the patient complained of a new type of pain different from the previous pain pattern. Computerized tomography and colonoscopy were arranged and colonic hematoma was found. Since the patient had stable vital signs, no special treatment was given focusing on the colonic hematoma. Five days later, P-ESWL treatment was repeatedly performed for four consecutive days. Two days after the last P-ESWL session, the patient underwent endoscopic retrograde cholangiopancreatography. At the three-month follow up visit, the colonic hematoma disappeared and pancreatic stones decreased significantly.
CONCLUSIONS: To the best of our knowledge, colonic hematoma after P-ESWL for pancreatic stones has never been reported. Here, we present the only case of colonic hematoma after P-ESWL, which was coincidentally found in more than 6000 P-ESWL sessions in our hospital. As the symptoms of colonic hematoma are mild, we believe the incidence of colonic hematoma has been underestimated. Many people with colonic hematoma after P-ESWL may be undiagnosed or misdiagnosed. Treatment for colonic hematoma depends on whether there is severe clinical state. Exploration of more precise location method for pancreatic stones may reduce the probability of P-ESWL complication.
