RESUMEN
Multiple plastic stent (MPS) for biliary anastomotic stricture (AS) after liver transplantation requires multiple procedures with consequent costs. To compare the success, adverse events and treatment-related costs of fully covered self-expandable metal stents (FCSEMS) versus MPS. Thirty liver transplant (LT) patients with clinically relevant naïve AS were prospectively randomized to FCSEMS or MPS, with stent numbers increased at 3-month intervals. Treatment costs per patient were calculated for endoscopic retrograde cholangiopancreatography (including all devices and stents) and overall hospital stay. Radiological success was achieved in 73% of FCSEMS (median indwelling period of 6 mos) and 93% of MPS patients (P = NS) (median period of 11 mos). AS recurrence occurred in 36% of FCSEMS and 7% of MPS patients (P = NS), and AS re-treatment was needed in 53% and 13% (P < 0.01), respectively, during follow-up of 60 (34-80) months. Stents migrated after 29% and 2.6% of FCSEMS and MPS procedures, respectively (P < 0.01). Including re-treatments, long-term clinical success was achieved in 28/30 (93%) patients. Overall treatment-related costs were similar between groups. In the subgroup of LT patients in clinical remission after first-line treatment, treatment costs were 41% lower per FCSEMS patient compared with MPS patients. FCSEMS did not perform better than MPS. FCSEMS migration increased the rate of re-treatment and costs.

OBJECTIVES: We conducted a study in order to assess the prevalence of extrapancreatic malignancies (EPMs) in a cohort of patients with intraductal papillary mucinous neoplasms (IPMNs) from northeastern Italy. METHODS: A study was conducted in hospital Santa Maria della Misericordia, Udine, Italy. Hospital records were screened in order to identify newly diagnosed IPMN cases in the period from January 1, 2009, to December 31, 2015. We searched for EPMs diagnosed previous to, synchronous to, or after the IPMN. The ratio of the observed (O) number of patients with EPMs to the expected (E) was calculated. RESULTS: We identified 72 EPMs in 63 (31.8%) of 198 patients included. Among them, 51 (70.8%) were diagnosed previous to, 17 (23.6%) synchronous to, and 4 (5.6%) after the IPMN. Most frequently diagnosed were colorectal (12 patients [6.1%]), breast (8 patients [6.8%, in females]), renal cell (8 patients [4.0%]), and prostate cancer (7 patients [8.6%, in males]). The O/E ratios for EPMs were significantly increased for cancer in general (3.66; 95% confidence interval [CI], 2.39-5.37), renal cell (9.62; 95% CI, 1.98-28.10), prostate (4.91; 95% CI, 1.59-11.45), and breast cancer (3.16; 95% CI, 1.03-7.37). CONCLUSIONS: We report an increased risk of EPMs in patients with IPMN, especially for renal cell, prostate, colorectal, and breast cancer.
