| pubmed-article:1759160 | pubmed:abstractText | 70 patients clinically classified as n.a.d. were sonographically examined for evaluation of the gallbladder fossa within two weeks after cholecystectomy. Four marked signs were noted. In 35 patients (50%) we found homogeneous echogenic formations of triangular, band-like, or oval shape in the bed of the gallbladder. In 25 cases (35.7%) inhomogeneous structures were seen. In 6 cases (8.5%) cystic structures resembling the normal gallbladder were seen which were interpreted as representing seromas or liquified haematomas. In 4 patients (5.7%) the bed of the gallbladder was entirely normal. Whether the gallbladder bed was closed by sutures or not, had no statistically significant effect on ultrasound appearance. | lld:pubmed |
