System I is based on the serum transaminase alone: system 2 uses alkaline phosphatase and bilirubin in addition to transaminase; and system 3 involves female gender, age, amylase and alkaline phosphatase in addition to transaminase. Over the 4-year period 1983-86, 368 patients with 391 episodes of acute pancreatitis had clinicobiochemical analysis within 48 h. Of these episodes, 220 were related to gallstones (56 per cent), 62 to alcohol (16 per cent) and 109 to other aetiologies or were idiopathic (28 per cent). Significant differences were found between the biliary and non-biliary groups with respect to sex (139 versus 59 women, P&amp;lt;0\u00b7002), age (65\u00b117 versus 52\u00b119 years, P&amp;lt;0\u00b70001) and serum amylase (6041\u00b16335 versus 4546\u00b13990 units\/l, P&amp;lt;0\u00b70001), alkaline phosphatase (257\u00b1225 versus 141\u00b1137 units\/l, P&amp;lt;0\u00b70001), alanine transaminase (221\u00b1227 versus 72\u00b1119 units\/l, P&amp;lt;0\u00b70001) and bilirubin (40\u00b139 versus 24\u00b130 \u03bcmol\/l, P = 0\u00b70001). The sensitivity and specificity was 75 per cent and 74 per cent for the one-factor system, 74 per cent and 78 per cent for the three-factor system and 62 per cent and 80 per cent for the five-factor system. The predictive value of a positive result was 78\u00b18 per cent, 81\u00b15 per cent and 80\u00b71 per cent and of a negative result 69\u00b74 per cent, 70\u00b71 per cent and 62\u00b73 per cent for the three systems respectively. The performances of the one- and three-factor systems were marginally better than that of the five-factor system; the one-factor system, however, had the advantage of simplicity.<\/jats:p>","DOI":"10.1002\/bjs.1800750308","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T10:52:27Z","timestamp":1172919147000},"page":"213-215","source":"Crossref","is-referenced-by-count":34,"title":["Biochemical prediction of gallstones in acute pancreatitis: A prospective study of three systems"],"prefix":"10.1093","volume":"75","author":[{"given":"B R","family":"Davidson","sequence":"first","affiliation":[{"name":"Department of Surgery Leicester Royal Infirmary , Leicester,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J P","family":"Neoptolemos","sequence":"additional","affiliation":[{"name":"Department of Surgery Leicester Royal Infirmary , Leicester,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"Leese","sequence":"additional","affiliation":[{"name":"Department of Surgery Leicester Royal Infirmary , Leicester,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D L","family":"Carr-Locke","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Leicester Royal Infirmary , Leicester,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[1988,3,1]]},"reference":[{"key":"2024092719505238700_bib1","first-page":"367","article-title":"Early surgery for acute gallstone pancreatitis.
