BACKGROUND: The feasibility and immediate outcome of laparoscopic fenestration for patients with congenital liver cysts have been generally recognized. The aim of the present study was to assess the long-term results after laparoscopic fenestration. METHODS: A retrospective study was performed on 44 patients with congenital liver cysts who had undergone laparoscopic fenestration between June 1998 and December 2004. Among them, 30 were women and 14 men, aged 57 years on average (range 18-76 years). While 14 patients had solitary cysts, 20 had multiple cysts, and 10 had polycystic liver disease. The results of laparoscopic fenestration, including mortality, morbidity, mean postoperative hospital stay, and recurrences of cysts were evaluated. RESULTS: There was no perioperative death and the morbidity rate was 11% (5/44). All complications were treated conservatively. The mean postoperative hospital stay was 4 days. A mean follow-up of 57 months showed that the rates of cyst recurrence and symptom recurrence were 9% and 4.5%, respectively. CONCLUSION: Laparoscopic fenestration as a feasible and safe treatment procedure for patients with congenital liver cysts can yield very good long-term results.

BACKGROUND: The incidence of extrahepatic cholangiocarcinoma increases in recent years. But the diagnosis and treatment are still troublesome to surgeons. This study was designed to explore the value of surgical approach in the treatment of extrahepatic cholangiocarcinoma. METHODS: We retrospectively analyzed the clinical data of 135 patients with extrahepatic cholangiocarcinoma who had been treated in our hospital from January 1992 to December 2006. RESULTS: The ratio of extrahepatic cholangiocarcinoma to biliary duct diseases was 1.81%. The rates of total resection and radical resection were 70.75% (75/106) and 56.60% (60/106), respectively. The overall 1-, 3-, 5-year survival rates were 46.93%, 37.33% and 18.75%, respectively. The 1-, 3-, 5-year survival rates were better in the radical resection group (74.94%, 55.74% and 41.27%, respectively) than in the palliative resection group(42.86%, 26.79% and 26.79%, respectively) (P<0.05). The survival rates of patients who had undergone palliative resection were higher than those of patients who had been subjected to palliative drainage or non-operation: 1-, 3-,5-year survival rates were 42.86%, 26.79%, 26.79% vs. 23.33%, 6.67%, 0 or 17.86%, 0, 0 (P<0.05). While the survival rates were not significantly different between palliative drainage and nonoperation (P<0.05). Multivariate analysis revealed that the histopathological grades, TNM stages and modalities were key factors influencing the outcome. CONCLUSIONS: The outcome of the patients with extrahepatic cholangiocarcinoma is still not optimistic. Radical resection is the first choice for the treatment of tumors.

The interactions between avian brood parasites and their hosts provide an informative and easy-to-handle system for studying *** brood parasitism reduces the reproductive success of hosts,and thus,hosts have evolved anti-parasitic strategies,such as rejecting parasitic eggs and adopting aggressive nest defense strategies,to avoid the cost brought on by brood *** test whether host anti-parasitic strategies are adjusted with the risk of being parasitized when the breeding seasons of brood parasites and hosts are not synchronous,we conducted a field experiment assessing nest defense and egg recognition behaviors of the Isabelline Shrike(Lanius isabellinus),a host of the Common Cuckoo(Cuculus canorus).In the local area,the host Isabelline Shrike begins to breed in April,whereas the summer migratory Common Cuckoo migrates to the local area in May and begins to lay parasitic *** showed that nest defense behaviors of the Isabelline Shrike increases significantly after cuckoo arrival,showing higher aggressiveness to cuckoo dummies,with no significant difference in attack rates among cuckoo,sparrowhawk and dove dummies,but their egg rejection did not change *** results imply that Isabelline Shrikes may adjust their nest defense behavior,but not egg rejection behavior,with seasonality.

BACKGROUND: Glycogen storage disease (GSD) is an inherited metabolic disorder in which the concentration and/or structure of glycogen in tissues is abnormal. Essentially, abnormalities in all known enzymes involved in the synthesis or degradation of glycogen and glucose have been found to cause some type of GSD. Liver and muscle have abundant quantities of glycogen and are the most common and seriously affected tissues. This study was to assess reduced-size liver transplantation for the treatment of GSD. METHODS: The clinical data from one case of GSD type I with hepatic adenoma was retrospectively analyzed. The clinical manifestations were hepatomegaly, delayed puberty, growth retardation, sexual immaturity, hypoglycemia, and lactic acidosis, which made the young female patient eligible for reduced-size liver transplantation. RESULTS: The patient recovered uneventfully with satisfactory outcome, including 12 cm growth in height and 5 kg increase in weight during 16 months after successful reduced-size liver transplantation. She has been living a normal life for 4 years so far. CONCLUSIONS: Reduced-size liver transplantation is an effective treatment for GSD with hepatomegaly and hepatic adenoma. Delayed puberty, growth retardation, hypoglycemia and lactic acidosis can be cured by surgery.

BACKGROUND: Hepatic artery thrombosis (HAT) is a frequent complication following liver transplantation, but it is rarely caused by arcuate ligament compression of the celiac artery. This article mainly describes our experience in managing a patient with celiac artery stenosis and HAT after liver transplantation. METHODS: A 44-year-old man with a 15-year history of hepatitis B was admitted to our hospital for hepatocellular carcinoma. Before the operatiori, he received transarterial chemoembolization once, and pretransplant MR angiography indicated a suspected stenosis at the initiation of the celiac artery, while color Doppler showed normal blood flow in the arterial system. In this case, orthotopic liver transplantation was performed for radical cure of hepatocellular carcinoma. However, B-ultrasonography detected poor blood flow in the intra- and extra-hepatic artery on the first posttransplant day, and during exploratory laparotomy a thrombus was found in the hepatic artery. Thus, re-transplantation was conducted with a bypass between the graft hepatic artery and the recipient abdominal aorta with the donor's splenic artery. RESULTS: The patient made an uneventful recovery and color Doppler showed good blood flow in the artery and portal system. Histology confirmed extensive thrombosis in the left and right hepatic artery of the explanted graft, indicating HAT. CONCLUSIONS: Although HAT caused by celiac trunk compression is rarely reported in liver transplantation, the diagnosis should be considered in patients with pretransplant hepatic artery stenosis on angiography and abnormal blood flow on B-ultrasonography. Once HAT is formed, treatment such as thrombectomy or retransplantation should be performed as early as possible.
