Background: Several reports claim that there is a risk that laparoscopic ch
olecystectomy (LC) might worsen the prognosis of unsuspected gallbladder ca
ncer.
Hypothesis: Several factors rather than LC could influence prognosis.
Methods: A retrospective clinicopathologic study was performed on 20 patien
ts, 9 patients (3 men and 6 women, aged from 36 to 75 years [mean age, 62.3
years]) undergoing LC and 11 patients (2 men and 9 women, aged from 53 to
91 years [mean age, 65.3 years]) undergoing open cholecystectomy (OC), with
postoperatively diagnosed gallbladder cancer. The correlation was evaluate
d between cumulative survival rates and the following 7 prognostic factors:
age, sex, histopathological grade, pathologic stage, occurrence of bile sp
illage, type of cholecystectomy (LC or OC), and additional surgical treatme
nts.
Results: Seven patients (87%) after LC and 9 patients (82%) after OC had ca
ncer recurrence: the difference is of no statistical significance (P=.9). T
here were no recurrences of cancer in the abdominal wall after either LC or
OC. Survival rate was statistically correlated to tumor stage (P=.007) and
to the occurrence of bile spillage (P=.002). Survival rate did not change
according to whether the operation was carried out using LC or OC (P=.60).
Conclusion: These results would seem to lend support to the opinion that LC
does not worsen the prognosis for unsuspected gallbladder cancer.
