A nationwide cohort study of resection rates and short-term outcomes in open and laparoscopic distal pancreatectomy.

Abstract

BACKGROUND\nDistal pancreatectomy (DP) is increasingly done by laparoscopy but data from routine practise are scarce. We describe practise in a national cohort.\n\n\nMETHODS\nData from the Norwegian Patient Register of all patients undergoing DP from 2012 to 2016. National resection rates were analysed. Short-term outcomes include length of stay, reoperation, readmissions and 90-day mortality. Risk is reported as odds ratio (OR) with 95% confidence interval (c.i.).\n\n\nRESULTS\nOf 554 procedures, 327 (59%) were laparoscopic. Median age was 66 years (iqr 55-72) and 52% were women. Resection rates increased during the period for all DP (from 1.76 to 2.39 per 100.000/yr), and significantly for laparoscopic DP (adjusted R-square 0.858; P\xa0=\xa00.015). Elderly patients had more resection (r2\xa0=\xa00.11; P\xa0=\xa00.019). Splenectomy (n\xa0=\xa0427; 77%) was less likely with laparoscopy (laparoscopy 72% vs open 84%, respectively; OR 0.64, 95% c.i. 0.42-0.97; P\xa0=\xa00.035). Multivisceral resections occurred more often in open DP (5.3% vs 1.2% for laparoscopy, OR 4.51, 1.44-14.2; P\xa0=\xa00.008). Reoperation occurred in 34 (6%), readmission in 109 (20%), and mortality in 8 (1.4%). Hospital stay was shorter for laparoscopic DP.\n\n\nCONCLUSION\nUse of DP increases in the population, particularly in the elderly, with use of laparoscopic access and an association with a reduced hospital stay.
