ObjectiveTo evaluate the diagnosis and operative modality for superior mesenteric artery compressing syndrome (SMACS).MethodsThe clinical data of 28 SMACS cases from January 2000 to December 2010 at this hospital was analyzed retrospectively.ResultsAll patients underwent barium meal examination and the diagnosis was established according to clinical symptom and barium study. The 28 cases of SMACS underwent surgical treatment. The operative modalities included lysis and downward movement of the Treitz ligament and extensive mobilization of the duodenum in 4 cases, gastrojejunal anastomosis in 2 cases, lysis of the Treitz ligament and Roux-en-Y duodenojejunostomy in 11 cases, Billroth Ⅱ gastrectomy in 7 cases, and anterior duodenojejunostomy in 4 cases.All patients were cured and discharged from hospital.ConclusionsThe diagnosis of SMACS should mainly on barium meal examination besides the typical clinical manifestations such as epigastric distending pain and vomiting. Lysis of the Treitz ligament and Roux-en-Y duodenojejunostomy is appropriate surgical procedure to deal with SMACS.

Objective To explore the reasons and preventive measures for the postoperative complications of hilar cholangiocarcinoma.Methods The clinical features,diagnosis,surgical therapy,postoperative complications and follow-up result were retrospectively analyzed on 89 cases of hilar cholangiocarcinoma admitted into our hospital from January 2008 to September 2014.Surgical approach:47 cases of radical resection including hepatoduodenal ligament skeletonized resection in 18 cases; concurrent partial hepatectomy in 29 cases,palliative resection in 17 cases,biliary tract drainage in 25 cases.There were 6 cases receiving partial portal vein resection and reconstruction.Results Among 89 patients there were 93 postoperative complications.Biliary complications developed in 22 cases (24.7％,22/89) including bile leakage in 13 cases (14.6％),biliary tract infection in 7 cases,anastomotic stricture in 2 cases.Wound infection in 19 cases,lung infection in 4 cases,ascites in 31 cases,pleural effusion in 10 cases,liver abscess in 1 case,intraabdominal bleeding in 2 cases,postoperative gastrointestinal bleeding,intestinal fistula,liver failure and multiple organ failure (MODS) developed in one each cases.One case died of MODS with the mortality of 1.1％.Conclusions Postoperative complications were common in hilar cholangiocarcinoma combined liver resection and/or vascular resection and reconstruction.Bile leakage is the most frequently seen necessitating long term proper drainage.

Objective To investigate the clinical features and the prognosis after surgical treatment for hilar cholangiocarcinoma (HCC).Methods The surgical therapy and follow-up result were retrospectively analyzed on 98 cases of hilar cholangiocarcinoma admitted into our hospital from January 1995 to January 2005.Differences between groups were evaluated using Chi-square analysis or Student t-test according to the data type.Survival rate was calculated with Kaplan-Meier method,and using the log-rank test.Results Among 98 patients,83 patients underwent surgical treatment (radical resection in 33,palliative resection in 16,and nonresectional internal or external bile duct drainage in 34),15 patients underwent conservative therapy.The 1-,3-,5-year survival rates were 79％,42％,and 17％ in the resection group and 88％,54％,and 24％ in the radical resection group,respectively.The 1-,3-year survival rates were 55％,and 9％ in palliative resection group,respectively,and none of the patient survived for over 5 years.There were significant differences in the survival rate among the radical resection group and the palliative resection group (log-rank test,P ＜ 0.001).Conclusions Radical resection improves the prognosis of hilar cholangiocarcinoma.

Objective To explore the technical knowhow and experience of mesohepatectomy for central region liver disease.Methods The clinical data of 86 patients with liver disease in central region undergoing mesohepatectomy were retrospectively analysed in Henan Provincial People's Hospital,including 49 males and 37 females.There were 47 cases of central liver cancer,15 cases of hilar cholangiocarcinoma,4 cases of hepatic hemangioma,13 cases of gallbladder cancer,and 7 cases of intrahepatic cholangiolithiasis in central liver.25 cases received accurate hepatectomy (group A) and 61 cases did irregular hepatectomy (group B).Results In group A,15 cases did Ⅳ,Ⅴ and Ⅷ lobectomy,10 cases underwent Ⅳ and Ⅴpartial lobectomy.Among the irregular hepatectomy group (group B),35 were treated with hepatic middle lobe resection,26 with local middle liver resection.There were significant differences in operation time,degree of postoperative liver function damage between the two groups (P ＜ 0.05),while there was no difference in postoperative complications (P ＜ 0.05).Conclusions The accurate mesohepatectomy can reduce the incidence of postoperative liver function damage and surgical complications.
