Existing adhesion scores primarily measure morphological characteristics of adhesions that do not necessarily correlate with morbidity. The aim of this study was to develop a clinical adhesion score (CLAS) measuring overall clinical morbidity of adhesion-related complications in abdominal and pelvic surgery.<h4>Methods</h4>An international Delphi study was performed to identify relevant score items for adhesion-related complications, including small bowel obstruction, female infertility, chronic abdominal or pelvic pain, and difficulties at reoperation. The CLAS includes clinical outcomes, related to morbidity of adhesions, and weight factors, to correct the outcome scoreSurgical endoscopy2159-2168https://www.ebi.ac.uk/biostudies/studies/S-EPMC8057995biostudies-literatureClinical adhesion score (CLAS): development of a novel clinical score for adhesion-related complications in abdominal and pelvic surgery.PMC8057995Cheong Yvan der Wal JBCvan der Wees PJBakkum EAnsaloni LBurcharth JWilson MStommel MWJDi Saverio SSugrue MParker MTulandi TGerner Rasmussen JSchreinemacher MLundorff PFleshman JWDiamond MPDupre AVerguts JWiseman DMGawria LKluger YLeppaniemi AKumakiri JCatena FSong YSvan den Beukel BAWKoninckx Pvan den Hil LWallwiener MHackethal ABeck DELier EJde Wilde RLOuaissi MBouvy NDCLAS CollaborationKramer Bvan Goor HTen Broek RPGMais VCoccolini FTrew GSallinen VfalseClinical adhesion score (CLAS): development of a novel clinical score for adhesion-related complications in abdominal and pelvic surgery.<h4>Background</h4>Adhesions are a major cause of long-term postsurgical complications in abdominal and pelvic surgery.
