Article: Duodenum-Preserving Pancreatic Head Resection vs. Pancreatoduodenectomy for Benign Lesions and Low-Grade Malignancies of the Pancreatic Head.[show abstract] [hide abstract]
ABSTRACT: Background/Aims: To compare the postoperative results of duodenum-preserving pancreatic head resection (DPPHR) techniques with those of conventional pancreatoduodenectomy (PD). Methodology: We retrospectively reviewed the records of 58 patients who underwent DPPHR or PD at Jinhua central hospital between May 1998 and May 2011. Results: Eighteen patients underwent DPPHR (Group 1) and 40 conventional PD (Group 2). They were followed up for more than 6 months. Operation time in Group 1 was longer (290±18min vs. 269±14min, p=0.001). Estimated blood loss in Group 1 was more (633±88mL vs. 495±131mL, p=0.003). Intraoperative transfusion in Group 1 was more (533±88mL vs. 335±218mL, p=0.001). However, postoperative transfusion was less (141±162mL vs. 440±193mL, p=0.000). Group 1 had a lower short-term complication rate (16.67% vs. 50.0%, p=0.016) and long-term complication rate (11.11% vs. 45.0%, p=0.012). Hospital mortality of both groups were 0. Conclusions: DPPHR for benign or premalignant lesions is a difficult procedure, but with a lower complication rate than conventional PD. Preserving the entire duodenum and a normal biliary tree allows better short-term and long-term results. DPPHR will be suitable for only a small group of patients and should be performed by experienced surgeons.Hepato-gastroenterology 07/2012; 60(121). · 0.66 Impact Factor
Article: Preoperative assessment of hilar cholangiocarcinoma: combination of cholangiography and CT angiography.[show abstract] [hide abstract]
ABSTRACT: Hilar cholangiocarcinoma is one of the most difficult carcinomas to manage because of the location of the main tumor at the hepatic hilus and the complex anatomy of the biliary, arterial, and portal systems. To plan an operation, it is important to acquire accurate information about the relationship between hilar cholangiocarcinoma and adjacent vessels. This study aimed to evaluate the clinical value of cholangiography combined with spiral CT three-dimensional (3D) angiography for a preoperative assessment of hilar cholangiocarcinoma. From March 2007 to August 2009, cholangiography was performed in 13 patients with hilar cholangiocarcinoma. Meanwhile, contrast-enhanced abdominal scanning was performed using 16-slice spiral CT, and the 3D images of the hepatic artery and portal vein were acquired. The level and range of invasion of the hepatic artery, the portal vein, and the bile duct, the preoperative Bismuth classification, and T-staging were recorded and compared with those after surgical exploration. The hepatic artery and portal vein were reconstructed successfully in all these patients. Percutaneous transhepatic cholangiography was performed in 9 patients, endoscopic retrograde cholangiopancreatography in 1, and magnetic resonance cholangiopancreatography in 3. The CT angiography records of invasion of the hepatic artery were consistent with the results of explorations in these patients. The data from 5 of the 13 patients were consistent with those on invasion of the portal vein. The results of the Bismuth classification and the T-staging system were consistent with those of surgical exploration in 12 of the 13 patients. Seven of 8 patients who were estimated to be suitable for operation based on images were curatively treated and 5 who were judged to be unsuitable for curative operation by cholangiography and CT angiography were confirmed intraoperatively and underwent palliative procedures. Cholangiography combined with multi-slice spiral 3D CT angiography can satisfactorily delineate the local invasion of hilar cholangiocarcinoma and accurately evaluate the resectability. This approach, therefore, contributes to the planning of safe operation.Hepatobiliary & pancreatic diseases international: HBPD INT 04/2010; 9(2):186-91. · 1.08 Impact Factor

ABSTRACT: To explore the indications and effect of surgical resection for hepatic metastases from colorectal adenocarcinoma and to discuss the implications of clinicopathologic features on the prognosis. A retrospective study of 61 patients undergoing hepatectomy for metastatic tumors from colorectal adenocarcinoma from January 1991 to December 2000 in our hospital was performed retrospectively. The 1-, 3- and 5-year survival rates after hepatic resection were 72.13%, 58.10% and 26.01% respectively. Complications occurred in 8 cases. Tumor pesudomembrance was found in 20 cases. Dukes stage, pathologic type,the number of hepatic metastases and tumor pesudomembrance were all significant factors for prognosis after surgery (P< 0.05). The 3-year survival rate of the patients with postoperative comprehensive treatment was higher than that with non-postoperative treatment (P< 0.05). The size of hepatic metastases and the resecting time didn't affect the prognosis (P > 0.05). The hepatic metastases from colorectal cancer should be treated by a surgical approach. The earlier stage of clinical pathology,higher differentiation extent, metastases less than 3, the formation of pesudomembrance of the metastatic tumor and the postoperative comprehensive treatment predict a better survival.Zhonghua wei chang wai ke za zhi = Chinese journal of gastrointestinal surgery 10/2005; 8(5):440-2.
