carcinoma.

BACKGROUND: To clarify the cholangiographic findings of early-stage (T1,
tumor confined to the mucosal or fibromuscular layer) extrahepatic bile
duct carcinoma. METHODS: Cholangiographic images were retrospectively
analyzed without other information in 55 patients with extrahepatic bile
duct carcinoma who underwent surgical treatment. Tumor stages were T1 (n
= 10). T2 (n = 17), and T3 (n = 28). Cholangiographic findings were
classified as "diffuse sclerosis," "stenosis," "papillary polypoid
filling defect," or "nodular polypoid filling defect". "Papillary
polypoid filling defect" was the term used when the width of the base
was smaller than the width of the polypoid filling defect. RESULTS: T1
patients showed papillary polypoid filling defects (n = 8) or nodular
polypoid filling defects (n = 2) on cholangiography. When
cholangiography showed papillary polypoid filling defects, 8 of the 14
resected patients showed T1 stage tumor histologically. CONCLUSIONS: In
this study, 57% (8/14) of resected patients with papillary polypoid
filling defects showed T1 stage tumor. No T1 stage tumor showed stenosis
or diffuse sclerosis.

The prognostic significance of intratumoral angiogenesis was
investigated in 62 patients with stage I-III carcinomas of the
gallbladder treated with simple cholecystectomy. Microvessel density
(MVD) was assessed immunohistochemically, using the alkaline
phosphatase/anti-alkaline phosphatase method and the monoclonal antibody
CD31. The mean MVD was 30.5 vessels per x 200 optical field. Using the
thirty-third and the sixty-sixth percentile, the patients were grouped
into three MVD categories: low (MVD 9-18; 20 patients), medium (MVD
19-31; 20 patients), and high (MVD 32-86; 22 patients). A high MVD was
more frequent in well-differentiated adenocarcinomas compared with
moderately and poorly differentiated tumors (p = 0.04), but there was no
statistically significant association between MVD and T stage, or
patients' age or sex. Multivariate analysis, including MVD, T stage, and
histologic grade, showed that MVD was a significant independent
prognostic factor in carcinomas of the gallbladder (p = 0.001, t ratio
3.3). It is believed that the assessment of intratumoral angiogenesis in
patients with operable gallbladder carcinomas may be useful in
predicting prognosis and, perhaps, in decision making for postoperative
adjuvant treatment.

Incidental gallbladder carcinoma (GBC) is a difficult management issue
as there are no established guidelines. Laparoscopic cholecystectomy is
associated with increased dissemination of the tumour cells (both in the
peritoneal cavity and port sites). Depth of tumour invasion (T stage)
and positive surgical margins are the most important prognostic factors,
although tumour differentiation, lymphatic, perineural and vascular
invasion may also affect the outcome. Simple cholecystectomy is adequate
for mucosal (T1a) lesions only. For T1b tumours port site/wound excision
with second radical operation (probably extended cholecystectomy --
wedge liver excision with regional lymphadenectomy) should be advised.
T2 tumours should be treated with second radical operation (extended
cholecystectomy or excision of medial liver segments 4b and 5 or 4, 5
and 8 with regional lymphadenectomy with or without excision of the
extra-hepatic bile duct). Few T3 tumours can be cured and in some
survival time may be prolonged by a second radical operation. More
extensive liver resection (segments 4b and 5 or segments 4, 5 and 8)
with regional lymphadenectomy with excision of the extra-hepatic bile
duct should be advised. A second radical operation may palliate some T4
tumours. In the absence of extensive nodal disease, this operation may
prolong the survival time. Excision of the extra-hepatic bile duct
should be undertaken whenever the tumour involves the cystic duct margin
or the extra-hepatic biliary tree. Epidemiology, risk factors,
aetiopathogenesis and the modes of spread of GBC are discussed in
relation to appropriateness of the second radical operation.
Indications, types and role of the second radical operation are
discussed. Copyright Harcourt Publishers Limited.

BACKGROUND: The purpose of this study was to clarify the efficacy of,
and define the indications for, extensive surgery for gallbladder
carcinoma. METHODS: Between 1979 and 1994, 116 patients with gallbladder
carcinoma underwent operation. Radical resection was performed in 80
patients. RESULTS: In 68 patients with stage III or IV disease,
extensive resection including extended right hepatectomy (n = 40),
pancreaticoduodenectomy (n = 23) and/or portal vein resection (n = 23)
was employed to achieve complete tumour excision. The hospital mortality
rate was 18 per cent. The postoperative 3- and 5-year survival rates
were 44 and 33 per cent respectively in the patients with stage III
disease (n = 9), and 24 and 17 per cent respectively in patients with
stage IV (M0) disease (n = 29). In contrast, the postoperative survival
rate for the 30 patients with stage IV (M1) disease (7 per cent at 3
years and 3 per cent at 5 years) was worse than that for patients with
stage III and stage IV (M0) disease (P = 0.009 and P = 0.062
respectively). CONCLUSION: Radical resection should be undertaken for
stage III and stage IV (M0) gallbladder cancer. Although portal vein
resection and/or pancreaticoduodenectomy did not contribute to long-term
survival, better survival was obtained than that for the unresected
patients.

BACKGROUND: Cancers of the pancreas and periampullary region are rarely
curable. We set out to determine the efficacy of laparoscopy with
laparoscopic ultrasound in the staging of pancreatic and ampullary
(LS) of tumors already deemed resectable by standard radiologic criteria
in 27 patients using laparoscopy with laparoscopic ultrasound (LUS).
Patients found to be resectable by LS evaluation underwent laparotomy
(LA). We then compared the results of the LS and LA findings. RESULTS:
Of the 27 patients evaluated, 17 were men and 10 were women. Their mean
age was 66 years. Preoperative computerized tomography (CT) scans were
done in all 27 patients (100%), and transabdominal and endoscopic
ultrasound (EUS) was done in 21 (78%). By LS, seven patients (26%) were
found to have unresectable disease. Two patients with mesenteric tumor
infiltration (one with peritoneal implants, and one with a visible liver
metastasis) were judged to be unresectable by laparoscopy alone. LUS
revealed that one patient had portal vein (PV) occlusion and two had
metastases to the lymph nodes or liver that were not revealed by
preoperative studies or laparoscopy alone. Among 20 patients (74%)
deemed resectable by LS, two (10%) were found to be unresectable at LA,
one due to PV involvement and the other due to local tumor extension
with superior mesenteric lymph node metastasis. Eighteen of those in
whom resection was attempted (90%) were resectable, with no unexpected
findings of distant lymph node or hepatic metastasis. Pathology
examination showed that eight had regional metastases (44%). The
sensitivity of LS in determining unresectability was 77% (seven true
positives and two false negatives). The negative predictive value
(reflecting resectability) was 90%. Laparoscopy alone had a sensitivity
of 44%, with a negative predictive value of 78%. The sensitivity and
positive predictive value of LS was 100%, reflecting no false positive
examinations. CONCLUSIONS: LS can effectively stage most patients and
reliably predict which of them will benefit from LA. Intervention for
unresectable patients can then be limited to laparoscopic or endoscopic
bypass. The main limitation is that LS may underestimate PV and regional
lymph node involvement.

BACKGROUND: During the last 2 decades, endoscopic retrograde
cholangiopancreatography (ERCP) has been widely used for the diagnosis
of periampullary tumors and the preoperative or definitive treatment of
jaundice. METHODS: We performed a retrospective analysis of 319
consecutive patients (184 men and 135 women with an average age of 66.5
years) who underwent ERCP for periampullary tumors between 1987 and
1999. RESULTS: Endoscopic internal biliary drainage was successful in
293 patients (92%), with some differences due to the origin of the
tumor. There were five complications (1.5%), including four bleeds and
one retroduodenal perforation. There were no deaths related to the
endoscopic drainage. Eighty-four patients underwent
pancreaticoduodenectomy. The postoperative morbidity rate was 23%, and
the overall mortality rate was 4.8%. CONCLUSION: ERCP is a valid
technique for the detailed preoperative assessment of periampullary
tumors. It is also a safe method for internal biliary drainage.
