Abstract

Surveillance protocol after resection of branch duct IPMNs (BD-IPMNs) is determined based on the following factors: (1) pathological grade of resected BD-IPMNs, (2) pancreatic margin status after partial pancreatectomy, (3) presence of the residual lesions left without resection in the remnant pancreas, (4) presence of concomitant PDACs at the time of operation, (5) the possibility of metachronous occurrence of BD-IPMNs, and (6) development of concomitant PDACs in the remnant pancreas. Yearly risk of PDAC development is reported to be 0.7-0.9 % in the patients with BD-IPMNs, and thus international consensus guidelines suggest that CT or MRCP at 6-month intervals is appropriate for surveillance after resection of BD-IPMNs, even though the resected IPMN is benign with negative surgical margin. Surveillance with shorter interval should be considered in patients who underwent resection of invasive IPMNs, who had positive surgical margin status, or who have significant clinical signs to suspect the progression or new development of the disease.
