ABSTRACT

Objective:To study the clinical results of personalized surgical treatment for portal hypertension based on portal venous hemodynamics.Methods:A retrospective study was performed on patients with portal hypertension who underwent surgical treatment from January 2016 to December 2020 at the People’s Hospital of Ningxia Hui Autonomous Region and Wuhai People’s Hospital. Of 229 patients included into this study, there were 156 males and 73 females, with age of (4±11) years old. Portal vein CT and ultrasound doppler examination were performed preoperatively and portal vein manometry and ultrasound doppler examination were performed intraoperatively to evaluate portal venous hemodynamics. Based on the evaluation results, different surgical treatments were adopted. Postoperative complications and results of the operations were recorded. Long-term outcomes were evaluated by the rate of recurrence of gastroesophageal varices which was classified as disappearance, mild, moderate and severe according to endoscopic findings.Results:All the 229 patients completed the operations successfully. All together 13 operative treatments were used: (1) simple splenectomy ( n=11); (2) devascularization ( n=176), including 86 patients with splenectomy combined with extensive devascularization, 44 patients with splenectomy combined with selective devascularization and with preservation of paraesophageal veins, 39 patients with splenectomy combined with selective devascularization and reconstruction of spontaneous portosystemic shunt (34 patients with selective devascularization and reconstruction of spontaneous gastrorenal shunt and 5 patients with selective devascularization and reconstruction of spontaneous splenorenal shunt), 4 patients with secondary devascularization for variceal recurrence and 3 patients with devascularization and preservation of spleen; (3) shunt procedures were performed in 42 patients including 21 patients with splenectomy combined with coronary renal shunt, 11 patients with splenectomy combined with coronary-caval shunt, 6 patients with distal splenorenal shunt, 2 patients with proximal splenorenal shunt combined with devascularization, 1 patient with right gastroepiploic vein-inferior vena cava shunt and 1 patient with trans-inferior mesenteric vein coronary renal shunt. There were no operative deaths. The Clavien-Dindo grade 3 and above postoperative complication rate was 6.6% (15/229). Two hundred and eight patients were followed up for 6-60 months, with a median follow-up of 38 months. Severe recurrent varices were found in 21 patients (10.1%, 21/208), with 5 patients (2.4%, 5/208) presented with variceal bleeding. The rate of severe varices after selective shunting and selective devascularization by reconstructing the spontaneous portosystemic shunt (4.2%, 3/72) was significantly lower than that of the other devascularization procedures (13.7%, 17/124)(χ 2=4.53, P=0.033). Conclusion:Better clinical results were achieved by selecting the appropriate surgical procedures based on portal venous hemodynamic characteristics of patients. Selective shunting and selective devascularization by reconstructing the spontaneous portosystemic shunts significantly reduced the recurrence rate of severe varies.

ABSTRACT

Objective:To evaluate the preventive effect of proximal splenic vein ligation after splenectomy on the splenic vein originated portal vein thrombosis (PVT) in portal hypertension.Methods:The clinical data of 94 patients of portal hypertension who had received splenectomy were retrospectively analysed. The proximal splenic vein was ligated in 36 cases during pericardial devascularization and coronary renal shunt with splenectomy. The other 58 cases who had received pericardial devascularization without proximal splenic vein ligation served as control. All of the patients in both groups were given heparin infusion postoperatively through the catheter which was placed in the right gastroepiploic vein during operation. CT portal veinography was performed at the 7th-14th postoperative day for detection of PVT.Results:None of the PVT occurred in the splenic vein ligation group. In the control group, PVT occurred in 22 cases(38%) and splenic vein thrombosis occurred in all the 58 cases (100%). PVT incidence between the two groups is significantly different (0 vs. 38%, χ 2=17.828, P<0.05). Conclusions:Ligation of the proximal splenic vein during splenectomy can effectively prevent the postoperative splenic vein originated PVT in portal hypertension.

ABSTRACT

Objective To compare the efficiency of laparoscopic cholecystectomy (LC) and radical cholecystectomy (RC) in the patients with early gallbladder carcinoma. Methods From January 2001 to December 2008, 63 patients who had underwent LC(28 cases) or RC(35 cases) were analyzed retrospectively. The survival and recurrence rate after operation and complication were compared. Results After treatment, the complication in the LC group was less than that in the RC group (7. 1% vs. 48. 6%, χ2 = 12. 675 ,P <0.01). In the RC group,the 1,3,5 year overall cumulative survival rate of Nevein phase Ⅰ were all 100%, and 76. 2%, 42. 9%, and 23. 8% respectively in the phase Ⅱ. The overall cumulative survival rate of LC cases were 81.8%, 54. 5%,27.3% in phase Ⅰ and 17.6% ,5.9% ,0.0% in phase Ⅱ, respectively. The survival curves between the two groups were significantly diffierent(phase Ⅰ χ2 =20.74,P<0.001; phase Ⅱ χ2 = 11.35,P<0.001) and the survival rate in the RC group was higher than that in the LC group. The 1,3,5 year cumulative recurrence rates in the RC were 20.0%, 48. 6%, 68. 6%, respectively, which is significantly lower than those in the LC group (60.7%,85.7% and92.9%, respectively)(χ2 =10.30,P=0.0013).Conclusions RC is one of the first choices for early gallbladder carcinoma treatment, and will decrease the recurrence rate and improve the long-term life quality.

ABSTRACT

Objective To determine the value of detection of micrometastasis in peripheral blood to hepatocellular carcinoma (HCC) metastasis or recurrence. Methods Reviewed the related literatures, the methods and significances of the detection of HCC micrometastasis in peripheral blood were analyzed. Results Currently, there are mainly two methods, hematogenous dissemination cell detection and HCC specific mRNA biomarker detection, for detection of HCC micrometastasis in peripheral blood. Theoretically, although they are considered as early detections of HCC metastasis or recurrence, researches still not have a abroad agreeable conclusion from different studies. After adjusting and improving the methods and detection time, different studies also have not gotten a quite consistent conclusion. Conclusion There is a great significance in detection of HCC micrometastasis in peripheral blood to understanding the mechanisms of HCC metatasis and recurrence, and also to improving the clinical therapy. Theoretically and practically, the method should be improved for facilitating the mechanism research of HCC metastasis and recurrence, and the application of detection.
