RESUMEN
<p><b>BACKGROUND</b>Choledochal cyst excision and biliary enteric reconstruction constitute the best therapy for choledochal cyst. And laparoscopy is currently used to cure this disease now.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 34 cases of total laparoscopic choledochal cyst excision between January 2007 and August 2011. All patients underwent in vitro Roux-en-Y hepatoenterostomy.</p><p><b>RESULTS</b>All 34 patients underwent successful total laparoscopic choledochal cyst excision. The operation time was 200 - 360 minutes. The duration of hospital stay was 3 - 7 days. Follow-up observations lasted 1 - 56 months. One patient developed an anastomotic stoma stricture, but no other cases had postoperative complications. No patients died.</p><p><b>CONCLUSION</b>Total laparoscopic choledochal cyst excision is safe and feasible.</p>

<p><b>OBJECTIVE</b>To summarize the clinical experience with diagnosis and treatment of intrahepatic biliary cystadenoma (IBCA).</p><p><b>METHODS</b>We retrospectively analyzed the data of 10 consecutive IBCA cases treated in our department in light of the characteristics of the epidemiology, radiology, lab tests, pathology and prognostic.</p><p><b>RESULTS</b>The patients are all female with an average age of 48.9 (16-73) years. The number of asymptomatic, slightly symptomatic and severe symptomatic patients was 4, 4 and 2, respectively. Radiological examination showed segmented cystic lesions in all the cases with an average diameter is 13.3∓4.9 cm. The incidence of segmentation, papillary or nodular hyperplasia, and calcification within the lesions was 90%, 60% and 20%, respectively. Macroscopic examination of the specimen showed compartmentation in the lesions, and microscopically, the lesions all showed lining of cubic or columnar epithelium on the inner wall with ovary-like or fibrous stroma. Complete resection of the tumor was achieved in 8 cases and partial resection was performed in 2 cases. The patients were followed up for a mean of 55.3 (12-164) months, and none of the patients with complete tumor resection showed recurrence, while both of the two patients with partial resection had postoperative recurrence.</p><p><b>CONCLUSION</b>IBCA is a rare cystic lesion occurring primarily in middle-aged women. The preoperative diagnosis of this disease relies primarily on radiological evidences, and a complete resection of IBCA may prolong the patient survival.</p>

<p><b>BACKGROUND</b>Liver transplantation is the most effective treatment for end-stage liver diseases; however, infections after transplantation can seriously affect the patient's health. The aim of this research was to investigate the diagnosis and treatment of fungal infection following liver transplantation.</p><p><b>METHODS</b>Clinical data for 232 liver transplant patients at risk of fungal infection were examined for the presence of fungus in the blood, fluid, sputum, urine and stools of patients and by chest or abdominal CT scans. Patients diagnosed with a fungal infection were treated with Fluconazole or, if this was not effective, Voriconazole or Amphotericin B. Immunosuppressive therapy was also reviewed.</p><p><b>RESULTS</b>Thirty-seven of 232 (15.9%) patients were diagnosed with a fungal infection, which occurred 4 to 34 days post-transplantation. Candida infections were diagnosed in 23 cases (62.2%) and Aspergillus infections in 12 cases (32.4%). Twenty-one cases were effectively treated with Fluconazole, 11 cases with Voriconazole, and two cases with Amphotericin B; however, three cases were not effectively treated with any of the antifungal agents. Overall, treatment was effective in 91.9% of patients.</p><p><b>CONCLUSIONS</b>Fungal infection has a significant influence on survival rate after liver transplantation. Imaging studies, and pathogenic and biopsy examinations can diagnose fungal infections, which can be effectively treated with antifungal agents such as Fluconazole, Voriconazole or Amphotericin B.</p>

<p><b>OBJECTIVE</b>To evaluate the early results of precise liver resection.</p><p><b>METHODS</b>Between May 2006 and June 2009, 65 patients with complicated liver space-occupying lesions were included in the study. Fifty-one patients underwent curative liver resection. Liver resections performed included 16 trisectionectomies, 11 hemihepatectomy, 5 meso hepatectomies, 3 combined segmentectomies, 5 caudate lobectomies and 11 irregular local resections.</p><p><b>RESULTS</b>Patients undergoing resection had no mortality with a major morbidity of 9.8%. Nineteen vascular repairs and reconstructions were patent at last follow-up. The postoperative 1-year survival rate was 100% in 10 patients with benign lesions and 92.7% in 41 patients with malignant tumors. The 1-year survival rate was zero in patients with malignant tumors, who underwent no liver resection.</p><p><b>CONCLUSIONS</b>Precise liver resection, as an aggressive surgical approach, offers hope for these patients, who would otherwise have a dismal prognosis.</p>

<p><b>OBJECTIVE</b>To analyze clinical typing, pathologic characteristics of hilar cholangiocarcinoma (HCCA) and surgical strategies and their effects on HCCA, and to explore the factors that influence the surgical outcomes and long-term survival.</p><p><b>METHODS</b>The data of the 402 patients with HCCA admitted between January 1993 and December 2004 was investigated retrospectively. Primary outcomes examined included clinical typing, pathologic characteristics, surgical procedures and follow-up results. On the basis of Bismuth-Corlette typing, we defined the tumor originated from intrahepatic large bile duct (LBD) as type V (type Va and Vb).</p><p><b>RESULTS</b>Among the 402 patients with HCCA, 198 cases accepted curative resection, 102 (51.5%) for radical resection and 96 (48.5%) for palliative resection. Of the rest patients, 8 received orthotopic liver transplantation (OLT), 161 received simple drainage and 35 were not operated on. The resection rates for type I, II, IIIa, IIIb, IV, Va and Vb were 69.4%, 55.5%, 57.4%, 71.7%, 19.6%, 100% and 34.6%, respectively. The one-year survival rates for radical resection, palliative resection, simple drainage and untreated were 80.3%, 53.2%, 26.7% and 9.8%, respectively. And the three-year and five-year survival rates in the four groups were 41.9% and 33.3%, 19.6% and 14.7%, 3.3% and 0, 0 and 0, respectively. Significant difference was found in survival rates between the radical and palliative resection. In the patients who received tumor resection, the ones without lymph nodes metastasis (LNM) survived much longer than those with LNM (P < 0.05). Complications were found in 36.1% of the patients and the mortality rate was 0.3%.</p><p><b>CONCLUSIONS</b>HCCA type V originated from intrahepatic LBD has higher resection rate and better prognosis. The tumor differentiation is significantly correlated with the prognosis after operation. With HCCA, resection is still the major treatment selection. Curative resection carries the best effect. Extended radical resection of liver lobes, blood vessels, lymph nodes can prolong survive. The problem of high recurrence rate after OLT for HCCA has not been solved yet.</p>
