An Observation of the Protective Effects of SAdenosylLMethionine on Liver Function in Cirrhotic Rats after Hepatectomy

ObjectiveTo investigate the protective effect of SadenosylLmethionine on liver regeneration and liver function in cirrhotic rats after hepatectomy. MethodsCirrhosis was successfully induced by injection of 40% CCl4.Then,partial hepatectomy (about 30%) was performed in all rats. Cirrhotic rats were divided into 3 groups,namely,cirrhotic group (normal saline 5 ml/d,for 15 postoperative days，n=20),treatment group 1 〔S adenosylLmethionine 10 mg/(kg·d),for 15 postoperative days,n=16〕 and treatment group 2 〔SadenosylL methionine 20 mg/(kg·d),15 postoperative days,n=16〕,and normal control group was also established. Animals were sacrificed at the 15th postoperative day and 30th postoperative day to take samples for detection of liver function (Alb,ALT,TB,TBA) and serum TNFα.Liver tissues were also observed under light microscope and electron microscope. ResultsIn two treatment groups,at the time point (15 postoperative days or 30 postoperative days),concentrations of ALT,TB,TBA,Alb and TNFα were decreased significantly as compared with cirrhotic group (P ＜0.01),and concentration of Alb was increased significantly (P＜0.01).In contrast, there were no obvious difference in the same time point of different dosetreatment groups (Pgt;0.05),but the decrease of ALT,TB,TBA,TNFα and the increase of Alb were more significant at the second time point (30th postoperative day) than the first time point (15th postoperative day) when treated with same dose (P＜0.01).At the same time,concentration between TNF α and ALT,TB,TBA showed a positive correlation (P＜0.01),and the concentration between TNFα and Alb showed a negative correlation (P＜0.01).In addition, the histopathology showed SadenosylLmethionine had effects of protecting liver function and enhancing liver regeneration. ConclusionThe study suggests that SadenosylL methionine has the efficacy of enhancing liver regeneration and improving liver function.

SURGICAL TREATMENT OF THE LOCALIZED LEFT HEPATOLITHIASIS

An retrospective analysis of 112 cases with localized left hepatolithiasis (LLH) treated in our center in recent two decades was made. The results showed: ①Coexisting involvements of both left external hepatic duct (LEHD) and left medial hepatic duct (LMHD) were the most common pathological pattern (83.08%), came next the only LEHD involvement (12.31%). There was no localized LMHD caculi in this group. ②The rate of concomitant LHD stricture was 59.82% and that of LMHD or LEHD were 84.85% and 84.00% respectively, in which severe degrees dominate. ③Lateral segmentectomy was the most common clinical practice for LLH (58.93%), and left lebectomy was much less frequently used (12.50%), although the latter led to a significantly smaller rate of residual (7.14% vs 21.21%) and had a satification follow-up rate of 85.71% being superior to lateral segmentectomy (46.97%), or cholangiojejunostomy (40.00%), bile duct exploration and drainage (0). ④The most common prognostic factors were residual or recurrent stones of LMHD (62.50%) and residual LHD stricture (37.50%). ⑤There was no significant difference between left lobectomy and lateral segmentectomy in length of operation, intraoperative bleeding, and postoperative complications. The results indicate that too much dependence on lateral segmentectomy in the management of LLH is one of the most important factors affecting the longterm results, for which left lobectomy is an applicable and safe therapy of choice.

Clinical Application on Hepatectomy Combined with Biliary Tract Exploration via The Bile Duct Stump in Treatment of Hepatolithus

ObjectiveTo evaluate the feasibility and effect of treatment of bile duct exploration though hepatic sections instead of spliting common bile duct, cured for hepatolithiasis with bile duct stones. MethodsClinical data of 122 cases of our hospital were retrospectively reviewed, these patients with left intrahepatic bile duct stone and common bile duct calculi. As control group, during the period from June 2007 to June 2010, in which 64 patients underwent left hepatic lobectomy, common bile duct exploration and T tube drainage. In observation group, 58 patients from June 2011 to December 2013, underwent left hepatic resection combined biliary duct exploration by the liver section stump bile duct. The operative time, intraoperative bleeding volume, postoperative hospitalization time, and incidence of complications between the 2 groups were compared. ResultsCompared with the control group, the postoperative hospitalization time was shortened obviously in observation group patients(P < 0.05), there were no significant difference in operative time and bleeding during operation of 2 groups(P > 0.05), The incidence of postoperative complications in the observation group was significantly lower than the control group(P < 0.05). In 122 patients, 105 cases were followed-up(86.1%), the follow-up time was 2 years. Two groups of patients had no stone residual and recurrence. ConclusionsBile duct exploration by intraoperative liver section is an effective method to treat left hepatolithiasis, it can simplified procedures, shortening the postoperative hospitalization time, and effectively avoid complications caused by common bile duct incision and T tubedrainage.
