Surgery is the standard treatment and margin-free resection is considered the most commonly employed treatment variant(AU)

Advances in diagnosis and treatment of intrahepatic biliary cystadenoma / 中华消化外科杂志

Intrahepatic biliary cystadenoma (IBC) is a rare benign cystic neoplasm of liver,with malignant potential to transform into intrahepatic biliary cystadenocarcinoma.IBC predominantly occurs in women up to 85％,showing no special clinical symptoms and a polycystic lesion inside the liver on image examination.It is difficult to differentially diagnose from other cystic lesions of the liver such as simple liver cyst,intraductal papillary neoplasm of the bile duct,etc.The missed diagnosis and misdiagnosis rate were rather high in IBC,which is accurately diagnosed by pathological examination.Complete surgical removal of the tumor is the best way to cure it,and also can bring a satisfactory outcome to patients.

Biliary Cystadenoma - A Case Report.

Biliary cystadenoma are rare cystic lesions of liver. They accounts for less than 5% of nonparasitic cyst of liver. Hueter first reported biliary cystadenoma in 1887. It is an extremely rare benign hepatic tumor arising from von meyerberg complexes. It occurs frequently in middle age between 40 and 50 years with female preponderance. We, hereby, report a case of 70 year male, who presented with mass and pain in the right upper abdomen

Diagnosis and treatment of biliary cystic tumors / 中华消化外科杂志

Biliary cystic tumors (BCTs) are rare cystic tumors and are accounted for less than 5％ of liver cysts.BCTs are very common in middle-aged and elderly women,and depend on diagnosis of imaging including papillary projection or multilocular cystic liver mass.BCTs are frequently misdiagnosed due to the absence of specific diagnostic indicators,which should differentiate from diagnosis of hepatic cystic.Complete surgical resection is the first choice for BCTs with a good out-come,in addition to low recurrence.Once recurrence was identified in follow-up,BCTs can be treated by reoperation with a good outcome.

A cystic hepatic lesion: when to worry? / La lesión cística del hígado: ¿cuándo preocuparse?

A 16-year old female presented to hospital with abdominal pain. Features on computed tomography raised the possibility of biliary cystadenoma or cystadenocarcinoma. She underwent a liver resection, and histopathology confirmed a serous biliary cystadenoma. This case is presented to highlight the radiological features of this uncommon pre-malignant condition as well as to summarize a management algorithm for cystic liver lesions.

Una mujer de 16 años de edad acudió al hospital con un dolor abdominal. Las características observadas con tomografía computarizada apuntaban a un cistoadenoma biliar o un cistoadenocarcinoma como diagnósticos diferenciales. La paciente fue sometida a una resección del hígado, y la histopatología confirmó un cistoadenoma biliar seroso. Presentamos este caso para resaltar los rasgos radiológicos de esta condición premaligna rara, así como para resumir un algoritmo de tratamiento para las lesiones císticas de hígado.

Thirteen Cases of Intrahepatic Biliary Cystadenoma and Cystadenocarcinoma: A Single Center Experience / 대한소화기학회지

BACKGROUND/AIMS: Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCACa) are rare cystic neoplasms that usually arise from the liver. We reviewed the clinicopathologic and radiologic findings of 13 cases of intrahepatic biliary cystic neoplasms. METHODS: Seven patients with BCA and 6 patients with BCACa which were pathologically proven within past 10 years were included in this retrospective study. RESULTS: BCA (7 of 7) was more common in female compared to BCACa (4 of 6). Mean age at diagnosis was 53.4 years (BCA) and 58.5 years (BCACa). Abdominal pain (54%) was the most common presenting symptom. Eleven patients (61.5%) exhibited normal liver function profiles and 5 patients (38%) showed elevated levels of serum CA19-9 levels (mean 894.2 U/mL, range: 78.7-2,080). Mean size of tumor was 11.7 cm (range: 5-15). Most frequent radiologic finding was a single cystic mass with septation. BCACa tended to have intracystic solid portion. The cut surface revealed a unilocular or multilocular cystic mass with mucinous contents. Complete surgical excision was done in 12 patients. After the complete resection, recurrence was observed in 1 case of BCACa. CONCLUSIONS: The possibility of biliary cystic neoplasm should be suspected when an intrahepatic cystic lesion with multiseptation or solid portion is noted on imaging study. In addition, complete excision for definite diagnosis and treatment need to be performed.

Three Cases of Biliary Cystadenoma and Biliary Cystadenocarcinoma

A biliary cystadenoma and a cystadenocarcinoma are rare intrahepatic cystic neoplasm. The clinical feature is not marked but abdominal fullness and mass are the most common symptoms. The tumor is commonly a large multilocular cystic mass which requires hepatectomy for cure. We experienced one case of biliary cystadenoma and two cases of biliary cystadenocarcinoma. The biliary cystadenoma case was a 58-year-old female with right upper quadrant discomfort for 5 months and a 17 cm sized multilocular cystic mass. The serum CA 125 level was elevated but returned to normal level after resection. A right hepatectomy was performed and the patient has had no recurrence for 14 months after the resection. One of the biliary cystadenocarcinoma cases was a 42-year-old man with a 12 cm sized multilocular cystic mass in the right upper quadrant of his abdomen. A right hepatectomy was performed and the patient has had no recurrence for 12 months after the resection. The other biliary cystadenocarcinoma case was a 70-year-old man with right upper quadrant pain and a 5 cm sized cystic mass. A left hepatecomy was performed and the patient has had no recurrence for 8 month after the resection. The treatment of choice for a biliary cystadenoma or cystadenocarcinoma is complete resection. We report three cases of biliary cystadenoma and cystadenocarcinoma with a review of the literature.

Cystectomy and Hepatic Resection for Cystic Lesion of the Liver

PURPOSE: Cystic lesions of the liver are highly variable in respect to appearance and therapeutic approach. However, without cystectomy and hepatic resection, the patient is at risk for recurrent enlargement, infection, or progression of an unrecognized malignant neoplasm. The goal of this study was to discern the safest and most effective method, with special emphasis on a suitable therapeutic technique for various cystic lesions of the liver. METHODS: We reviwed the cystectomy and hepatic resection and outcome of patients with hepatic cysts from November, 1987 to April, 2000 at the Hanyang University Hospital. A retrospective study of 19 patients with various cystic lesions of the liver was performed. RESULTS: There were 8 simple cysts, 2 polycystic liver disease, 2 biliary cystadenoma, 4 biliary cystadenocarcinoma, 2 hydatid cysts, and 1 traumatic cyst. In examining the 6 cystectomies, 13 hepatic resections. (4 right lobectomies, 4 left lobectomies, 5 minor hepatic resections), there were no postoperative deaths in this series. Four patients (21.1%) developed operative complications. During the mean follow- up time of 78.2 months, symptomatic relief was complete and permanent in all of patients except the 1 biliary cystadenocarcinoma 1 of the 4 patients with biliary cystadenocarcinoma died of tumor recurrence (5.3%) approximately 27 months after hepatic resection. CONCLUSION: Cystectomy and hepatic resection is a more curative treatment for cystic lesions of the liver than other treatments. We recommend complete cystectomy and hepatic resection as the preferred therapy, particularly when the cyst is large, a malignancy cannot be ruled out, and a proper diagnosis is not confirmed.

Solitary cystic lesions of the liver: Its diagnosis and Treatment / 한국간담췌외과학회지

BACKGROUND/AIMS: With the advances in imaging modalities, the incidental diagnoses of solitary cystic lesions of the liver are increasing. The aim of this study is to establish the strategy of differential diagnosis and treatment in the patients with solitary cystic lesions of the liver METHODS: Forty three solitary cystic lesions of the liver treated surgically at Seoul National University Hospital from January 1981 to December 1998 were reviewed retrospectively. The clinicopathologic features, postoperative courses and their long-term results were analysed. RESULTS: There were fifteen congenital nonparasitic cysts (simple cysts), 3 Caroli's diseases, 4 hydatid cysts, 2 traumatic cysts, 1 cystic hamartoma, 10 biliary cystadenomas, and 8 biliary cystadenocarcinomas. Twenty six hepatic resections, 12 excisions, 3 marsupializations, 1 cystojejunostomy, and 1 cystic wall biopsy were performed. There were 4 biliary leakages and 2 intraabdominal abscesses after surgery, and three out of them resulted from the communications with the biliary trees. Cystic fluid analysis or radiologic study could not offer the accurate diagonosis. Two patients who had biliary cystadenoma and biliary cystadenocarcinoma, respectively, and underwent marsupializations with preoperative misdiagnosis of simple cyst resulted in death due to recurrent tumors. CONCLUSION: In exploring every case of solitary cystic lesion of the liver, presence of biliary communication and cystic malignancy should be considered unless simple cyst is highly suggested.

Four Cases of Intrahepatic Biliary Cystadenoma and Cystadenocarcinoma

A biliary cystadenoma (BC) and a cystadenocarcinoma (BCA) are rare neoplasms of the liver. Among 178 patients with primary liver neoplasms who underwent surgery during the last two years at our department, there were only one case of BC and three cases of BCA. The BC case was a 57-year-old female with 15-cm-sized multilocular cystic mass containing mucin. That patient, who had undergone a simple excision of a liver cyst 6 years earlier under the diagnosis of a cystadenoma, received a repeated wedge resection and is still doing well, no recurrence, 41 months after the resection. One BCA case was a 59-year-old female with an 8-cm-sized multilocular cystic mass. She underwent an extended left lobectomy and is still alive, without recurrence, 55 months later. Another BCA case was 77-year-old female with multiple multilocular masses which had degenerated due to sclerotherapy; the masses were removed by a wedge resection. She has been alive 35 months without recurrence. The other BCA case was a 37-year-old female with a 10-cm-sized unilocular mass with lung metastasis. She underwent an extended left lobectomy and survived 22 months. Malignant transformation of a BC to a BCA is well documented, and recurrence is the rule following incomplete resection. Complete resection of a BC and radical resection of a BCA seem to offer a chance for long-term survival.
