DIAGNOSIS OF DEPTH OF INVASION OF GALLBLADDER CARCINOMA WITH ENDOSONOGRAPHY

We reported on the usefulness of endosonography (EUS) in the diagnosis of the depth of invasion of gallbladder carcinoma. We performed EUS on 69 patients with gallbladder carcinoma：the degree of tumor extension in 17 was m (tumor invading the mucosa), in 5 pm (tumor invading the muscular layer), in 21 ss (tumor invading the subserosa), 14 in se (tumor invading the serosa), and 12 si (tumor extending to adjacent organs). The detection rate of tumors with EUS was 91.3％ (63 of 69). All 6 (100％) patients with pedunculated lesions (lp type) were correctly diagnosed with EUS. Eighteen of 21 patients (85.7％) with broad-based elevated tumors (ls type), and 5 of 7 (71.4％) with flat-elevated lesions (Ila type) were also diagnosed correctly. EUS is a useful modality for the diagnosis of gallbladder carcinoma. In particular, EUS diagnosis of the depth of invasion ls reliable in Ip-type lesions. It is recommended that patients with lp-type lesions undergo laparoscopic cholecystectomy, but in patients with Is-or Ila-type lesions conventional cholecystectomy with lymph node resection should be performed.
