Gallstone ileus after biliointestinal bypass: report of two cases
No full textINTRODUCTION: Gallstone ileus is an uncommon disease and accounts for 1-4 % of all cases of mechanical intestinal obstruction. The physiopathology is related to the presence of a bilioenteric fistula.
METHOD: We report two cases of gallstone ileus in patients operated on biliointestinal bypass for morbid obesity. The anastomosis of the gallbladder to the proximal end of the bypassed jejunum allowed the transit of gallstones in the excluded ileum and its impaction in anti-reflux valvular system.
RESULTS: Preoperative exams were unable to solve the diagnostic query, and the diagnosis was achieved only at laparotomy. One-stage combined enterolithotomy and cholecystectomy were performed.
CONCLUSION: The two patients had an uneventful recovery. To our knowledge, this is the first report of gallstone ileus after biliointestinal bypas
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
