Branch-Type Intraductal Papillary Mucinous Neoplasms: An Update

Background/Aims: Branch-type intraductal papillary mucinous neoplasms (BT-IPMNs) are a subset of non-inflammatory mucinous lesions of the pancreas. Selected BT-IPMNs can be managed conservatively by surveillance because of their lower malignant potential. This review aims to update the reader on advances in our knowledge of BT-IPMNs since the consensus guidelines published in 2006. Methods: A Pubmed search for BT-IPMNs was undertaken and relevant papers were reviewed. Results: Due to the relative scarcity of this condition, still little is known about the natural history, the best method of surveillance or the surgical and non-surgical options. Conclusion: A national database of BT-IPMNs would enable a large enough cohort of patients to be followed up and valid conclusions drawn regarding the best method of treatment or surveillance.
