ABSTRACT
Objective To investigate the effect of Roux-en-Y hilar-jejunum anastomosis in surgical resection of hilar cholangiocarcinoma.Methods The clinical data of 31 patients with hilar cholangiocarcinoma admitted from Feb 2009 to Feb 2017 who underwent Roux-en-Y hilar-jejunum anastomosis after resection were retrospectively analyzed.Results According to Bismuth-Corlette classification there were 6 cases of Ⅲ a,6 cases of Ⅲ b and 19 cases of type Ⅳ.These patients all successfully underwent Roux-en-Y hilar-jejunum anastomosis,with intraoperative blood loss of 50-4 000 ml [on average of (1 146 ± 1 082) ml].The average operation time was (346 ± 118) min,and the average hilar-jejunum anastomosis time was (35 ± 13) min.The average postoperative hospital stay was (20 ± 11)days.There were 25 cases of R0 resection (80.6％).The postoperative complication rate was 25.8％(8/31).The overall median survival time was 21 months,and the 1-,3-,and 5-year survival rates were 68.8％,14.6％ and 3.6％,respectively.During the follow-up period,7 cases of reflux cholangitis,5 cases of biliary anastomotic stenosis,and 1 case of adhesive intestinal obstruction were found.Conclusion The hilar-jejunum anastomosis is simple,safe,widely applicable prcedure,which is easy to perform.
ABSTRACT
Objective To investigate the clinical efficacy and prognostic factors for combined caudate lobectomy radical resection plus broad lymph node dissection in patients of hilar cholangiocarcinoma.Methods The clinical data and follow-up results of patients with hilar cholangiocarcinoma surgically treated from Feb 2008 to Feb 2017 were retrospectively analyzed.Result The R0 resection rate[72.2％ (13/18) vs 43.9％ (18/41)],operation time [(433 ± 136) min vs (302 ± 122) min],intraoperative blood loss [(1 789 ± 1 091) ml vs (776 ± 755) ml] and postoperative complication rate [66.7％ (12/18) vs 36.6％ (15/41)]were significantly higher in the hepatic lobe combined with caudate lobe resection group than that without caudate lobe resection group (P ＜ 0.05).The median survival time of patients with enlarged lymph node dissection was longer than that of patients with regional lymph node dissection (33 months vs 13 months,P ＜0.05).Univariate and multivariate analysis showed that the preoperative serum CA199 level ＞ 1 000 U/ml,the degree of microscopic margin and tumor TNM stage were significantly correlated with the prognosis of the patients (P ＜ 0.05).Conclusion Combined with caudate lobe resection can improve R0 resection rate.Targeted lymph node dissection helps prolong survival.The degree of microscopic margin,preoperative CA199 and TNM staging are independent risk factors for the prognosis of patients with hilar cholangiocarcinoma.
ABSTRACT
Objective To investigate the diagnosis and treatment of upper gastrointestinal hemorrhage caused by pancreatic segmental portal hypertension.Methods The clinical diagnosis and follow-up data of 13 patients with upper gastrointestinal hemorrhage caused by pancreatic segmental portal hypertension from Jan 2010 to Dec 2017 were retrospectively analyzed.Results Of the 13 patients,5 had pancreatic pseudocysts and 8 had chronic pancreatitis.All of them had a history of hematemesis or (and) tarry feces,and 2 of them had a history of hemorrhagic shock.13 patients had isolated gastric varices,and 5 of them had varicose veins in the lower esophagus.13 patients had splenomegaly and hypersplenism,and all patients underwent splenectomy.All patients were followed up,and the varicose veins were significantly improved or disappeared.During 1 year to 8 years of follow-up,there was no rebleeding.Conclusion Splenectomy cures upper gastrointestinal hemorrhage caused by rupture of the varicose veins in patients of pancreatic segmental portal hypertension.Preoperative interventional spleen artery embolization can reduce the difficulty of spleen resection.
ABSTRACT
Objective To investigate the complication and risk factors in elderly patients undergoing pancreaticoduodenectomy (PD).Methods From Jan 2005 to Dec 2016,358 consecutive patients undergoing PD were divided into ≥ 70 years group (98 cases) and ＜ 70 years group (260patients).Perioperative complications were compared and risk factors explored between the two groups.Results There were differences in coronary heart disease between the two groups in the preoperative medical comorbidities (P =0.008),and that of albumin,alanine aminotransferase,alkaline phosphatase and creatinine (all P ＜ 0.05).Perioperative mortality was higher in the elderly group than in the younger group (P =0.038),probably related to higher systemic complications (P =0.001).The independent risk factors influencing the postoperative medical complications were preoperative total bilirubin ≥ 171 μmol/L and intraoperative blood loss ≥ 1 000 ml.Conclusions Patients over 70 years old have a comparatively higher perioperative mortality rate after pancreaticoduodenectomy,which were probably derived from a higher postoperative vital organ dysfunction.
ABSTRACT
Objective To evaluate the therapeutic effect or safety of selective paraesophagogastric devascularization with or without splenectomy for treatment of esophagogastric variceal hemorrhage.Methods The clinical data of 70 patients with a history of esophagogastric variceal hemorrhage from 2009 to 2015 were analyzed.29 cases received spleen preserving paraesophagogastric devascularization and 41 were given portoazygous devascularization plus splenectomy.Results Postoperative portal pressure in spleenpreserving group decreased 14％,that in splenectomy group decreased 23％ (t =2.87,P =0.01).The average blood loss in without splenectomy group was (829 ± 720) ml in contrast to (1 400 ± 1 329) ml in splenectomy group (t =2.311,P =0.024).Postoperative WBC and platelet count in without splenectomy group were lower (t =-5.379,t =-4.924,all P ＜0.01).The postoperative complication rate (24％ vs.39％),and portal venous thrombosis (10％ vs.31％) were all in favour of splenectomy free group (x2 =0.036,P ＜0.05).The 1-and 3-year's recurrent bleeding rate were 4％ and 8％ compared with 4％ and 8％ (all P ＞ 0.05).Conclusion Paraesophagogastric devascularization without splenectomy has less blood loss during the surgery,lower rate of PVT and comparable effect against post-op recurrent bleeding in contrast to devascularization plus splenectomy.
