ABSTRACT
Objective:To compare the clinical outcomes of treatment using non-selective versus highly selective partial splenic embolization in patients with hypersplenism secondary to liver cirrhosis.Methods:The clinical data of patients with hypersplenism secondary to hepatitis B cirrhosis who underwent splenic embolization at the Department of Hepatobiliary and Pancreatic Surgery of Leshan People's Hospital from July 2017 to July 2020 were analyzed retrospectively. Of 65 patients with hypersplenism, there were 42 males and 23 females, with age of (58.5±9.8) years. Twenty-six patients underwent splenic artery non-selective partial splenic embolization (the non-selective group) and 39 patients underwent partial splenic embolization using highly selective intubation (the highly selective group). The postoperative peripheral hematological indexes, liver function, operation-related complications and portal vein color Doppler ultrasonography were compared between the two groups.Results:The white blood cell count and platelet count of patients in the 2 groups were significantly higher than those before operation. The white blood cell count at 4, 12 and 24 weeks after operation and the platelet count at 12 and 24 weeks after operation in the highly selective group were significantly higher than those in the non-selective group ( P<0.05). Compared with the non-selective group, the total bilirubin, ICG-R15, portal vein diameter and portal vein blood flow in the highly-selective group significantly lower ( P<0.05). The incidences of 0/Ⅰ/Ⅱ/Ⅲ pain in the non-selected group was significantly higher when compared with that in the highly selected group (5/10/11/1 vs. 12/22/7/0), ( P<0.05). There were no significant differences in the incidences of postoperative complication between the two groups ( P>0.05). Conclusion:Compared with non-selective partial splenic embolization, highly selective partial splenic embolization gave more stable and lasting treatment outcomes in patients with hypersplenism caused by liver cirrhosis with better recovery of blood-related indicators, better improvement in postoperative liver function and relief of portal hypertension symptoms.
ABSTRACT
Objective@#To study the safety and effectiveness of infra-hepatic inferior vena cava clamping combined with Pringle’s maneuver during hepatectomy.@*Methods@#The databases of PubMed, Cochrane Center, CNKI, VIP, Wan Fang were searched to extract the relevant data for the meta-analysis using the Revmanage 5.3 software.@*Results@#A total of 14 studies with 1595 patients were included in this meta-analysis. The results showed that total bleeding during the combined clamping was significantly lower than that of the Pringle’s maneuver alone (MD=-314.59, 95%CI: -362.37~-266.81, P<0.05). Bleeding during hepatectomy was significantly lower (MD=-217.79, 95% CI: -284.57~-151.00, P<0.05); so was the intraoperative blood transfusion rate (OR=0.48, 95% CI: 0.36~0.62, P<0.05). The incidence of complications was significantly lower (OR=0.74, 95% CI: 0.57~0.95, P<0.05). However, there were no significant differences in operation time, length of hospital stay, intraoperative monitoring index and postoperative liver and kidney function recovery (P>0.05).@*Conclusions@#Infra-hepatic inferior vena cava clamping combined with Pringle’s maneuver in hepatectomy was safe and reliable. Compared with the Pringle’s maneuver alone, the combined technique reduce bleeding and the incidence of complications. This technique is worth promoting in clinical practice.

The incidence of complications was significantly lower (OR =0. 74, 95％ CI: 0. 57 ～0. 95, P<0. 05). However, there were no significant differences in operation time, length of hospital stay, intrao-perative monitoring index and postoperative liver and kidney function recovery ( P >0. 05 ) . Conclusions Infra-hepatic inferior vena cava clamping combined with Pringle' s maneuver in hepatectomy was safe and reliable. Compared with the Pringle' s maneuver alone, the combined technique reduce bleeding and the incidence of complications. This technique is worth promoting in clinical practice.
ABSTRACT
Objective To investigate the opportunity and skill of surgery for pancreatic sinistral portal hypertension.Methods Clinical data were retrospectively analyzed on 15 cases of pancreatic sinistral portal hypertension admired from Dec 2015 to Dec 2017.Results All fiften cases underwent surgical treatment,among them three cases were initially treated conservatively in the early stage and treated surgically for gastrointestinal bleeding,12 cases with definite pancreatic disease and pancreatic sinistral portal hypertension treated in the first stage.Three patients underwent second surgery for recurrent gastrointestinal bleeding.The patients were followed up for 6 to 18 months with symptoms significantly impioved without deaths.Conclusions Splenectomy combined with esophagogastric devascularization is the basic surgical treatment for pancreatic sinistral portal hypertension.
ABSTRACT
Objective To observe the effects of TLR9 on the nude mouse transplanted tumor growth of human pancreanc cancer and its drug resistance.Methods The nude mouse transplated tumor of human pancreatic cancer PANC-1 was established and randomly divided into 6 groups for conducting the experiment:sterile normal saline group,TLR9 agonist,TLR9 inhibitor group,gemcitabine group,TLR9 inhibitor plus gemcitabine Bin group,TLR9 agonist plus gemcitabine.The tumor size and growth situation were recorded by the vernier caliper.The immunohistochemical method was used to detect tumor TLR9 receptor expression.The tumor growth,metastasis and paracancerous nssue invasion situation were observed by the magnetic resonance imaging (MRI).Results The volume and growth speed of resected tumor mass in the gemcitabine group,TLR9 agonist + gemcitabine group,TLR9 inhibitor plus gemcitabine group was significantly smaller than those in other groups (P＜0.05),which in the TLR9 agonist + gemcitabine group were significantly greater than those in the TLR9 inhibitor plus gemcitabine group and gemcitabine group (P＜0.05),the difference between the TLR9 inhibitor plus gemcitabine group and gemcitabine group had statistical significance (P＜0.05),while the difference among the TLR9 agonist group,TLR9 inhibitor group and normal saline group had no stastistical significance (P＞0.05).The tumor in mice at 7 weeks after planting showed oval shape with clear boundary by MRI observation,no obvious metastais and paracancerous invasion were seen in paracancerous nssues no statistically significant,5 weeks,6 weeks after planting,seven weeks mice observed in MRI,the tumor into an,state clearly that the transfer of the surrounding tissue,no significant vascular invasion,heart,liver,kidney disease.The TLR9 expression on the surface of tumor tissue was detected and identified.Conclusion Pancreatic cancer nude mouse transplated tumor has definitely positive expression of TLR9,TLR9 activation can significantly decrease the sensitivity of pancreatic cancer to chemotherapy,increases the drug resistance of tumor,on contrary promotes the tumor growth.
ABSTRACT
For treatment of pediatric inguinal hernia, we fabricated a device, i.e. so called "filling type pediatric hernia sac", which treats the problem from the abdominal cavity, through the abdominal and is a self-adaptive closer, using synthetic material. The device includes filling rack, self-adaptive umbrella support bar, bottom piece, outside pulling line and device fixing lines. The filling rack is composed of 2 concentric circles of 3.0 cm diameter with peripherally fixed together and can be pulled into the shapes of a ball or an olive. The supporting bar is structured of 3 pieces with 0.5 cm wide, 4.0 cm long, cross-fixed on top of the filling rack. The bottom piece is in a circular structure with a diameter of 3.0 cm, and it is connected to the filling rack bottom. Adjust positioning stay outside the fixed on the top of the device are connected at one end, and the other end free through filling the top frame connected with the bottom slice of central fixation. By using this device, we treated 37 pediatric inguinal hernia cases with 38 side-inguinal hernia successfully. The mean duration of post-operation follow-ups was 14.6 ± 5.89 months, without hernia recurrence, obvious scar and hard sections of inguinal region. This device could provide a convenient, safe and effective plugging technology for children's pediatric hernia.
