ABSTRACT
Objective To analyze the causes of preoperative misdiagnosis of primary gallbladder carcinoma,and the effective measures of prevention of the misdiagnosis.Methods We retrospectively analyzed the clinicalrecords of 52 cases with primary gallbladder carcinoma that had been treated in our hospital in 10 years,and analyzed the causes of misdiagnosis.Results Nineteen cases were diagnosed preoperatively(36.5%),while 33 cases were misdiagnosed before operation(63.5%),including misdiagnsed as cholecystolithiasisin 13 cases,gallbladder polyps in 8cases,atrophic cholecystitis in 4cases,hepatic hilar cholangiocarcinoma in 3 cases,tumor of liver in 4 cases,and Mirizzi syndrome in 1 case.There were 29 casesdiagnosed during operation(55.8%),and 4 cases misdiagnosed intratoperatively(7.7%).Misdiagnosiswas due to several reasons:complicated with other gallbladder disease,lack of distinctive clinical features of gallbladder carcinoma,over dependence on imaging methods,and not doing fast frozen section duringoperation in dubious cases.Conclusions In suspected cases with high risk of gallbladder cancer,imagingstudies should be performed,and,if necessary,invasive studies and even exploratory laparotomy should be done.Also,intraoperative rapid frozen section can result in early discovery and treatment,and is conducive to improvement of prognosis of gallbladder carcinoma.
ABSTRACT
Objective To investigate the clinical manifesfations and diagnostic and therapeutic features of cholangiocarcinoma associated with hepatolithiasis.Methods The clinical data, the diagnotic and therapeutic featares of 54 cases of cholangiocacinoma associated with hepatolithiasis were retrospectively analyzed.Results The occurrence rate of hepatolithiasis concomitant with hepatocholangiocarcinoma was 11.8%.Due to a lack of specific clinical manifestations, the preoperative diagnosis of this condition was difficult. In this series, the (correct) diagnotic rate of hepatocholangiocarcinoma before operation was only 11.1%. The radical resection rate was 51.8%. Radical resection of the tumor had a better prognosis than that of non-resection of tumor.(Conclusions) Patients with long-term recurrent hepatolithiasis tended to have associated cholangiocarcinoma. Early diagnosis of the disease was difficult, and the treatment results and prognosis were poor. Therefore, (patients) with hepatolithiasis, espesially those with recurrent attacks, should undergo operation early. In cases diagnosed as hepatic cholangioearcinoma at operation, a radical resection should be performed, if possible, and a favorable outcome may be attained.
