Surgical Outcomes After Total Pancreatectomy: A High-Volume Center Experience.

BACKGROUND The impact of high-volume care in total pancreatectomy (TP) is barely explored since annual numbers are mostly low. This study evaluated surgical outcomes after TP over time in a high-volume center. METHODS All adult patients (age ≥ 18 years) who underwent an elective single-stage TP at Karolinska University Hospital were retrospectively analysed (2008-2017). High volume was defined as > 20 TPs/year. RESULTS Overall, 145 patients after TP were included, including 86 (59.3%) extended resections. Major morbidity was 34.5% (50/145) and 90-day mortality 5.5% (8/145). The relative use of TP within all pancreatectomies increased from 5.4% (63/1175) in 2008-2015 to 17.3% (82/473) in 2016-2017 (p   20 was associated with reduced major morbidity (odds ratio [OR] = 0.225, 95% confidence interval [CI], 0.097-0.521; p < 0.001). In the high-volume years (2016-2017), major morbidity (n = 31, 49.2% to n = 19, 23.2%; p = 0.001) and relaparotomy rate (n = 13, 20.6% to n = 5, 6.1%; p = 0.009) improved. Improvements occurred mainly after extended TP, including lower major morbidity (n = 22, 57.9% to n = 12, 25.0%; p = 0.002) and in-hospital mortality (n = 3, 7.9% to n = 0, 0%; p = 0.082). CONCLUSIONS In a single, high-volume center study, an increase in surgical volume of TP was associated with improved perioperative outcomes, especially for extended resections.
