BACKGROUND Despite pancreatic extracorporeal shock wave lithotripsy (P-ESWL) is a minimally invasive treatment for pancreatic stones, complications exist. CASE PRESENTATION 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.

体外冲击波碎石术治疗胰腺结石后的结肠血肿：1例。

背景技术尽管胰腺体外冲击波碎石术（P-ESWL）是胰腺结石的微创治疗方法，但仍存在并发症。病例介绍一名37岁的男性被诊断出患有慢性胰腺炎，并因复发性急性胰腺炎入院。在第一次P-ESWL疗程后，患者抱怨出现了一种新型疼痛，与以前的疼痛模式不同。安排了计算机断层扫描和结肠镜检查，发现了结肠血肿。由于患者的生命体征稳定，因此没有针对结肠血肿的特殊治疗。五天后，连续四天重复进行P-ESWL治疗。在最后一次P-ESWL疗程后两天，患者接受了内镜逆行胰胆管造影术。在三个月的随访中，结肠血肿消失，胰腺结石明显减少。结论据我们所知，从未报道过P-ESWL治疗胰腺结石后的结肠血肿。在这里，我们介绍了P-ESWL之后唯一的结肠血肿病例，该病例是在我们医院的6000多次P-ESWL疗程中偶然发现的。由于结肠血肿的症状较轻，我们认为结肠血肿的发生率被低估了。P-ESWL术后许多结肠血肿患者可能未被诊断或误诊。结肠血肿的治疗取决于是否存在严重的临床状态。探索更精确的胰腺结石定位方法可降低P-ESWL并发症的可能性。从来没有报道过P-ESWL治疗胰腺结石后发生结肠血肿。在这里，我们介绍了P-ESWL之后唯一的结肠血肿病例，该病例是在我们医院的6000多次P-ESWL疗程中偶然发现的。由于结肠血肿的症状较轻，我们认为结肠血肿的发生率被低估了。P-ESWL术后许多结肠血肿患者可能未被诊断或误诊。结肠血肿的治疗取决于是否存在严重的临床状态。探索更精确的胰腺结石定位方法可降低P-ESWL并发症的可能性。P-ESWL治疗胰腺结石后结肠血肿尚未见报道。在这里，我们介绍了P-ESWL之后唯一的结肠血肿病例，该病例是在我们医院的6000多次P-ESWL疗程中偶然发现的。由于结肠血肿的症状较轻，我们认为结肠血肿的发生率被低估了。P-ESWL术后许多结肠血肿患者可能未被诊断或误诊。结肠血肿的治疗取决于是否存在严重的临床状态。探索更精确的胰腺结石定位方法可降低P-ESWL并发症的可能性。由于结肠血肿的症状较轻，我们认为结肠血肿的发生率被低估了。P-ESWL术后许多结肠血肿患者可能未被诊断或误诊。结肠血肿的治疗取决于是否存在严重的临床状态。探索更精确的胰腺结石定位方法可降低P-ESWL并发症的可能性。由于结肠血肿的症状较轻，我们认为结肠血肿的发生率被低估了。P-ESWL术后许多结肠血肿患者可能未被诊断或误诊。结肠血肿的治疗取决于是否存在严重的临床状态。探索更精确的胰腺结石定位方法可降低P-ESWL并发症的可能性。
