T stage was T1 in 7.8 percent, T2 in 67.0 percent and T3 in 25.2 percent; the median interval to re-resection was 52 days. Residual or additional disease was found in 46.4 percent. Residual disease in the liver was found in 0, 10.4 and 36.4 percent of T1, T2 and T3 tumours and nodal metastasis in 12.5, 31.3 and 45.5 percent. A positive cystic duct margin predicted residual disease in the common bile duct (42.1 versus 4.3 percent). Common duct resection did not raise the lymph node count (median 3 in both groups).","asOf":"2026-09-24","links":[{"label":"J Gastrointest Surg 2007","url":"https://doi.org/10.1007/s11605-007-0309-6"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/17846848/"}],"tags":["gallbladder-evidence"],"related":[],"cancers":["gallbladder"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["incidental-gallbladder-cancer","radical-cholecystectomy","lymphadenectomy"],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"journal":"Journal of Gastrointestinal Surgery","year":2007,"doi":"10.1007/s11605-007-0309-6","pmid":"17846848","authors":"Pawlik TM, Gleisner AL, Vigano L, et al.","paperType":"observational","findings":["Residual or additional disease at re-resection in 46.4 percent of 115 patients.","Liver residual disease by T stage: T1 0 percent, T2 10.4 percent, T3 36.4 percent; nodal metastasis 12.5, 31.3 and 45.5 percent.","Positive cystic duct margin: residual disease in the common bile duct 42.1 vs 4.3 percent."],"whatItMeans":"This is the observational backbone of the rule that T1b or deeper incidental cancers should be re-resected, and of resecting the bile duct only when the cystic duct margin is positive.","caveats":["Retrospective series from referral centres; patients selected for re-resection.","Only nine T1 patients."],"changedPractice":true,"participants":115},"route":"/key-papers/paper-pawlik-incidental-gallbladder-cancer-residual-disease-jgs-2007/","neighbours":{"cancer":[{"id":"gallbladder","kind":"cancer","name":"Gallbladder cancer","route":"/cancers/gallbladder/"},{"id":"incidental-gallbladder-cancer","kind":"cancer","name":"Incidental gallbladder cancer (found after cholecystectomy)","route":"/cancers/incidental-gallbladder-cancer/"}],"term":[{"id":"lymphadenectomy","kind":"term","name":"Lymphadenectomy (lymph node dissection)","route":"/terms/lymphadenectomy/"},{"id":"radical-cholecystectomy","kind":"term","name":"Radical (extended) cholecystectomy","route":"/terms/radical-cholecystectomy/"}],"roadmap":[{"id":"gallbladder-cancer-roadmap","kind":"roadmap","name":"Gallbladder cancer roadmap: from a chance finding at gallstone surgery to a disease with its own trials","route":"/roadmaps/gallbladder-cancer-roadmap/"}],"idea":[{"id":"idea-gbc-t1b-simple-cholecystectomy-prospective-study","kind":"idea","name":"Test whether T1b gallbladder cancer needs the second operation at all","route":"/ideas/idea-gbc-t1b-simple-cholecystectomy-prospective-study/"}]}}
