METHODS: The charts of 9 patients who underwent surgery for intrahepatic biliary cystic liver neoplasms between 2003 and 2008 were reviewed retrospectively. Informed consent was obtained from the patients and approval was obtained from the designated review board of the institution. RESULTS: All patients were female with a median (range) age of 49 (27-60 years). The most frequent symptom was abdominal pain in 6 of the patients. Four patients had undergone previous laparotomy (with other diagnoses) which resulted in incomplete surgery or recurrences. Liver resection (n = 6) or enucleation (n = 3) was performed. The final diagnosis was intrahepaticbiliary cystadenoma in 8 patients and cystadenocarcinoma in 1 patient. All symptoms resolved after surgery. There has been no recurrence during a median (range) 31 (7-72) mo of follow up. CONCLUSION: In spite of the improvement in imaging modalities and increasing recognition of biliary cystadenoma and cystadenocarcinoma, accurate preoperative diagnosis may be difficult. Complete surgical removal (liver resection or enucleation) of these lesions yields satisfying long-term results.展开更多

It is conducted by having questionnaires and interviews among 220 students and by analyzing the teaching materials. The findings to the study indicate that the main obstacles are caused from the following aspects： neglecting the importance of developing vocabulary in the advanced study; neglecting activating the students＇ directing sense and detecting sense to difficult words; low rate of word recurrence in the teaching materials; requiring distinguishing the shade of the difference between synonyms excessively and too meticulously; overemphasizing the ＂negative transfer＂ of mother tongue; and some other obstacles to the development of lexical competence.展开更多
