Abstract

Introduction: A 68-year-old man with branch-duct intraductal papillary mucinous neoplasm (IPMN) in the pancreatic head presented with pancreatic ascites due to main duct rupture in the pancreatic body without typical pancreatitis symptoms.

Case presentation: Although the serum amylase level was elevated, the amylase level in the ascitic fluid was markedly higher. We hypothesize that mucin-induced downstream obstruction may have contributed to elevated intraductal pressure and upstream rupture. After conservative management, the patient developed delayed hemorrhage of approximately 4 months from the same site.

Conclusion: Based on a PubMed literature search, this appears to be the first reported case of pancreatic ascites followed by delayed hemorrhage from the same site associated with branch-duct IPMN.

分支导管内乳头状黏液性肿瘤同一破裂部位继发性胰腺腹水和胰血浆液1例。

简介：一名68岁男性胰腺头部分支导管导管内乳头状粘液瘤（IPMN），由于胰腺主体导管破裂导致胰腺腹水，无典型胰腺炎症状。病例介绍：虽然血清淀粉酶水平升高，但腹水淀粉酶水平明显升高。我们假设黏液诱导的下游阻塞可能导致导管内压力升高和上游破裂。在保守治疗后，患者发生了大约4个月的同一部位迟发性出血。结论：根据PubMed文献检索，这似乎是首例报道的胰腺腹水并发分支管IPMN相关部位迟发性出血的病例。
