ABSTRACT

Objective:To explore the diagnosis, surgical methods and therapeutic effect of primary duodenal malignant tumor.Methods:The clinical data of 116 patients with primary duodenal malignant tumor from January 2010 to December 2018 were retrospectively analyzed.Results:Among 116 patients, adenocarcinoma was in 74 cases, interstitial tumor was in 25 cases, carcinoid was in 9 cases, the others was in 8 cases. Before operation, duodenoscopy was performed in 107 cases, and CT examination was performed in 76 cases. There were 57 cases of pancreaticoduodenectomy, 15 cases of duodenal segmental resection, 13 cases of subtotal gastrectomy and duodenal bulbar resection, 13 cases of duodenal partial resection, and 18 cases of palliative short circuit operation. The total incidence of postoperative complication was 31.9% (37/116), including pancreatic fistula in 8 cases (grade B 5 cases, grade C 3 cases), biliary fistula in 6 cases, abdominal infection in 5 cases, pulmonary infection in 4 cases, intestinal fistula in 3 cases, delayed gastric emptying in 3 cases, and hemorrhage in 8 cases. Four cases (3.4%) died during the perioperative period. Single factor Cox regression analysis result showed that the postoperative survival time was related to the tumor differentiation degree, operation method, tumor infiltration degree and lymphatic metastasis ( P<0.05 or <0.01); multi-factor Cox regression analysis results showed that the operation method, tumor infiltration degree and lymphatic metastasis were the independent risk factors for the postoperative survival time of patients with primary duodenal malignant tumor ( P<0.05). The patients were followed up until June 2021, and 9 cases were lost to follow-up. Kaplan-Meier survival curve analysis result showed that the postoperative overall 1-,3- and 5-year survival rates were 82.11%, 57.56% and 33.11%, respectively. Conclusions:Adenocarcinoma is the main primary malignant tumor of duodenum. Duodenoscopy and CT are the main examination methods. Radical resection is the most effective treatment for primary duodenal malignant tumor, and pancreaticoduodenectomy is the first choice. Surgical method, tumor infiltration degree and lymphatic metastasis are the independent risk factors affecting the prognosis of patients.

ABSTRACT

Liquid-assisted surface desorption atmospheric pressure chemical ionization mass spectrometry (LA-DAPCI-MS)was used directly for the analysis of healthy rat liver (normal control group);acute alcoholic injury rat liver(alcohol model group)and Zhizi Dahuang decoction-treated rat liver (ZZDHD group)sections with the mass spectrometry images obtained simultaneously.Principal component analysis (PCA)was employed for the differentiation of livers of the groups;and 3 phospholipids;PC (34 ∶2);PC(36 ∶4)and PC(38 ∶4);were found to be the main factors.LA-DAPCI mass spectrometry images showed that the 3 phospholipids were evenly distrib-uted in liver under the spatial resolution of 0.01 mm2.Contents of 3 PCs in the model group were decreased in alcohol model group compared to the normal control group and the ZZDHD group;which revealed the relationship between acute alcoholic liver injury and intrahepatic phospholipid variation.The results showed that ZZDHD had protective effect on acute alcoholic liver injury-induced intrahepatic phospholipid variations at the molecular level.

ABSTRACT

ObjectiveTo investigate clinical application of intraoperative intraperitoneal hyperthermic chemotherapy using sustained-release fluorouracil in radical gastrectomy for advanced gastric cancer.MethodsThe clinical data of 280 advanced gastric cancer patients admitted from September,2002 to September,2010 were analyzed retrospectively.They were divided into three groups randomly and followed up.The postoperative morbidity,the mortality and the overall survival rates were evaluated.ResultsThere were no significant differences in these three groups with respect to postoperative morbidity ( P > 0.05 ).The incidence of recurrence in intraperitoneal chemotherapy using sustained-release fluorouracil ( treatment group) was significantly lower than those of intraperitoneal chemotherapy and operative treatment( 16.18%,37.61% and 41.28%,P <0.05).The 1,3- and 5-year overall survival rates of treatment group were 85.51%,61.28% and 53.67%,respectively,and the 1-,3- and 5-year overall survival rates were 84.11%,39.98% and 28.12%,and 81.28%,29.88% and 25.21% respectively in intrapeitoneal chemotherapy group and operative group.1-year overall survival rate had no significant differences among three groups with respect to ( P>0.05).3-and 5-year overall survival rates in treatment group were higher signfficantly than those of intraperitoneal chemotherapy and operative treatment( P<0.05).Conclusions Intraoperative intrapeitoneal hyperthermic chemotherapy using sustained-release fluorouracil is a kind of convenient,safe,and highly effective comprehensive treatment method,and it can kill isolated intraperitoneal cancer cells.It may reduce postoperative recurrence and improve survival rates.

ABSTRACT

Objective To investigate the approaches for diagnosis and treatment of intrahepatic cholangiocarcinoma(ICC)and asgess its prognosis factors.Methods The clinical data of 86 patients with ICC in our hospital from January 1995 to December2005 were retrospeetively analyzed.All patients were divided into two groups according to the treatment method,including hepatectomy and lymphatic clearance group(Group A,n=42)and hepateetomy group(Group B,n=44),and their clinicopathological variables were analyzed.Resuits The 1-,3-and 5-year survival rates were 77.81%and 35.21%,20.93%and 19.82%,2.31%and 0%respectively between group A and group B.There was significantly difference between these two groups(P<0.01).The analysis showed that resection and lymphatic clearance were correlated to prognosis.The 1-,3-and 5-year survival rates were 59.21%,26.21%,and 20.11% respectively in 47 patients who were found no lymph node metastasis,and the 1-,3-and 5-year survival rates were 19.82%,2.31%and 0% respectively in 39 patients who were found lymph node metastasis.There was significantly difference in survival rate between group A and group B(P<0.01).Condusions Reseetability and lymphatic clearance are two significant factors correlated to survival of the patients with ICC.Aggresgive treatment of lymph node metastasis in hepatoduodenal ligament is an important strategy to improve survival rates and strengthen patient's life quality.

ABSTRACT

Objective To study the diagnosis and radical resection of hilar cholangiocarcinoma. Methods Retrospective analysis was made on the clinical feature and the effect of radical resection on 38 cases of hilar cholangiocarcinomas.Results Diagnosis was made in all of the patients preoperatively.The radical resection was perfomed on 38 patients.Of them, 3(7.9%) died after operation.After operation, 5 cases (13.2%) developed bile leakage,and 2 of the 5 cases developed subphrenic abscess,which were cured by drainage; 4(10.5%) had right hydrothorax that was cured by conservative therapy; and 3(7.9%)had incision split that was cured by resuture. Among the 35 postoperative survivors,34 (97.1%) were followed up, the 1- and 3-year survival rates were 91.9% and 35.2%.None of the patients survived for 5 years. Conclusions It′s still difficult to make early diagnosis in hilar cholangiocarcinoma.The diagnosis mainly depends on the combination of imaging examinations. Nowadays the radical resection rate of hilar cholangiocarunoma is still low, the recurrence and metastasis are common after operation, and few patients can survive for a long time. It suggests that even in radical operation for hilar cholangiocarcinoma, the regions of resection and sweep are not enough,and the operative procedure needs to improve further.

ABSTRACT

Objective To investigate the effect of surgical treatment and the influence factors of treatment effect in patieats with hepatocellular carcinoma (HCC). Methods The clinical materials of 408 cases of HCC who underwent surgical intervention in recent 8 years were retrospectively analyzed. Results The 408 patients accounted for 43.9% of patients with HCC admitted during the same time. Of the 408 patients, large HCC accounted for 81.9% of patients, 8.5% of cases complicated by portal vein thrombus (PVT) ,and 4.8% of cases complicated by bile duct thrombus (BDT). In this series, 118 cases received left external lobectomy, 97 cases received left hemihepatectomy, 112 cases received right hemihepatectomy, 73 cases received right segmentectomy , 8 cases received left and righ segmentectomy ,35 cases received hepatectomy combining with removal of PVT , 20 cases received hepatectomy combined with thrombectomy of BDT; 48 cases received hepatectomy combined with implanment of drug delivery system (DDS) (35 patients with portal vein thrombus received DDS through portal vein). Three hundred and two cases had postoperative complications, including subdiaphragm abscesses,lung infection. upper digestive tract bleeding,pleural effusion ,ascites,wound spliting etc. Mortalily was 2.7%; cancer residual rate was 18.4%;postoperative recurrence and/or metastasis was 73.0%.The 1,3and 5-year survival rate was 73.9%,51.3%, 35.5 % respectively. Conclusions This results show that most of the patients with HCC received surgical operation treatment are in advanced stage, postoperative recurrence and/or metastasis are the main influence factors of treatment effect.
