The hepatic tissue that may occupy specimens from routine cholecystectomies has yet to be studied. Our objectives were to determine the prevalence of hepatic tissue obtained at routine cholecystectomy, to determine whether such hepatic tissue can histologically withstand technical artifacts commonly associated with cholecystectomy, and to determine whether examining such hepatic tissue has diagnostic utility. Materials and Methods. We retrospectively reviewed 50 specimens from routine cholecystectomies that were performed by surgeons who lacked knowledge of our study. All 50 specimens were grossed according to standard protocol, with only limited, nontargeted sampling of the rough nonperitonealized margin, and were received without fixative. Results. Twelve specimens (24.0%) contained hepatic tissue. The hepatic tissue measured up to 44.5-mm long and 1.8-mm wide and contained up to 11 complete portal tracts. Hepatic tissue in 3 specimens satisfied criteria for adequacy established for core biopsies based on number of portal tracts or size. Despite cautery and delayed fixation, all hepatic tissue had surprisingly well-preserved histology. Pathologic findings included nonalcoholic fatty liver disease, von Meyenburg complex, chronic cholestasis, and senescence. Conclusions. The hepatic tissue that accompanies specimens from routine cholecystectomies may be relatively common, can be large, is well preserved, and can harbor diagnostically useful information.<\/jats:p>","DOI":"10.1177\/1066896918817374","type":"journal-article","created":{"date-parts":[[2018,12,6]],"date-time":"2018-12-06T06:18:44Z","timestamp":1544077124000},"page":"499-505","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Incidental Hepatic Tissue Obtained via Routine Cholecystectomy"],"prefix":"10.1177","volume":"27","author":[{"given":"Vonny W.","family":"Tunru-Dinh","sequence":"first","affiliation":[{"name":"Western Reserve Care System, Youngstown, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suvarna A.","family":"Deshmukh-Rane","sequence":"additional","affiliation":[{"name":"University of California, Irvine, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0565-4076","authenticated-orcid":false,"given":"Mark Li-cheng","family":"Wu","sequence":"additional","affiliation":[{"name":"University of California, Irvine, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,12,6]]},"reference":[{"key":"bibr1-1066896918817374","unstructured":"Poggio JL, Raissis AC.
