ObjectiveTo summarize the various treatment methods for reducing jaundice in the elderly patients with malignant obstructive jaundice (MOJ), and provide reference for the treatment of elderly MOJ.MethodUsing “malignant obstructive jaundice” as the Chinese keyword and the English keyword, a computer search of the literatures on the treatment of elderly MOJ patients was conducted and reviewed.ResultsThe treatment methods of reducing jaundice in elderly MOJ included radical surgery, cholangiojejunostomy, endoscopic ultrasound-guided biliary drainage, endoscopic biliary stent implantation, percutaneous transhepatic biliary drainage and stent implantation. Radical surgery was the most effective, but it was traumatic and had many complications for elderly patients. Cholangiojejunostomy was effective and suitable for elderly patients who cannot tolerate major surgery. Endoscopic ultrasound-guided biliary drainage was less traumatic to elderly patients, but technical difficulty. Endoscopic biliary stent implantation was currently the first-line choice for the treatment of elderly patients with advanced MOJ. Percutaneous transhepatic biliary drainage and stent implantation were suitable for elderly and frail patients with high obstruction.ConclusionThe treatment of elderly MOJ needs to be individualized and regionalized, and appropriate treatment methods should be selected according to the patient’s condition and the medical level of the medical center.
Objective To analyze the influencing factors of short-term curative effect and long-term survival time of patients with tumor-induced malignant central airway obstruction (MCAO) after airway stent implantation. Methods A total of 120 patients with tumor-induced MCAO who underwent airway stent implantation in the hospital from January 2017 to June 2019 were enrolled. According to the cause of stenosis, the patients were divided into two groups: external pressure stenosis group (n=72) and non-external pressure stenosis group (n=48). The general data such as types and staging of tumor, differentiation degree, sites of airway obstruction, obstruction degree and preoperative level of lactate dehydrogenase (LDH). Before and at 7d after stent implantation, partial pressure of oxygen (PaO2), partial pressure of arterial carbon dioxide (PaCO2) and saturation of arterial blood oxygen (SaO2) were detected. Before and at 1 month after stent implantation, diameter at airway obstruction segment, degree of airway obstruction and forced expiratory volume in the first second (FEV1) were detected. Dyspnea index (DI) and scores of Karnofsky performance status (KPS) were evaluated. The survival status at 1 year after surgery was followed up. The survival at 1 year after surgery was analyzed by Kaplan-Meier. The influencing factors of survival after stent implantation were analyzed by COX proportional hazard regression analysis. Results After stent implantation, PaO2, SaO2, diameter at airway obstruction segment, FEV1 and KPS score were significantly increased (P<0.05), while PaCO2, degree of airway obstruction and DI were significantly decreased in external pressure stenosis group and non-external pressure stenosis group (P<0.05). After stent implantation, the KPS score was significantly higher in external pressure stenosis group than that in non-external pressure stenosis group, and the shortness of breath index was significantly lower than that in non-external pressure stenosis group (P<0.05). The survival rate of patients with external pressure stenosis group was 29.17%, and the median survival time was 7.35 months, the survival rate and median survival time in non-external pressure stenosis group was 22.92%, and the median survival time was 6.10 months, and there was no significant difference between the two groups (log-rank χ2=1.542, P=0.214). COX proportional hazard regression analysis showed that tumor staging at stage IV (OR=2.056, P=0.020), preoperative KPS score lower than 50 points (OR=2.002, P=0.027) and no postoperative chemoradiotherapy (OR=4.292, P=0.039) were independent influencing factors of 1-year survival time after stent implantation in MCAO patients. Conclusions The clinical curative effect of airway stent implantation is good on patients with tumor-induced MCAO. Tumor staging at stage IV, preoperative KPS score lower than 50 points and no postoperative chemoradiotherapy are risk factors that affect survival time.
ObjectiveTo evaluate safety and effectiveness of stent placement and emergency surgery in treatment of proximal colon cancer obstruction.MethodsThe PubMed, Embase, Cochrane Library, ClinicalTrials, CNKI, CBM, Wanfang Data, etc. were searched comprehensively. The literatures of Chinese and English randomized controlled trial and retrospective comparative study of stent placement and emergency surgery for the proximal colon cancer obstruction were retrieved. The RevMan 5.3 and Stata 12.0 softwares were used. The meta-analysis was made on the safety and effectiveness of these two treatments.ResultsA total of 9 literatures involving 636 patients were included, all of them were the retrospective studies, 4 of them only reported the clinical success rate and technical success rate. The technical success rate of stent placement was 0.94 [95% CI (0.91, 0.96)]. The clinical success rate was 0.90 [95% CI (0.87, 0.93)]. Compared with the emergency surgery group, the total complication rate and the temporary stoma rate were lower [OR=0.32, 95% CI (0.11, 0.94), P=0.04; OR=0.18, 95% CI (0.05, 0.65), P=0.009] and the hospital stay was shorter [MD=–2.97, 95% CI (–4.52, –1.41), P=0.000 2] in the stent placement group. The perioperative mortality rate, laparoscopic surgery rate, 5-year disease-free survival rate, and 5-year overall survival rate had no significant differences between these two groups (P>0.05).ConclusionCompared with emergency surgery, endoscopic stent placement for treatment of proximal colon cancer obstruction has a lower incidence of complications, temporary colostomy rate, shorter hospital stay, and it has no significant differences in mortality, laparoscopic surgery rate, and survival rate.
Objective To explore the effect of endovascular treatment guided by ultrasonography combined with portosystemic shunts on the patients with Budd-Chiari Syndrome （BCS）.Methods The clinical data of 136 patients with BCS treated by balloon angioplasty and stent implantation guided by Doppler ultrasonography in our hospital from January 1995 to January 2011 were retrospectively analyzed.After balloon angioplasty,53 patients were treated by inferior vena cava （IVC） stent implantation and 31 patients with hepatic venous occlusion underwent portosystemic shunts （PSSs） at one week after endovascular treatment.The long-and short-term effects after treatment were studied.Results After endovascular procedures,the IVC pressure of patients significantly decreased （P＜0.01）,while IVC diameter, flow velocity in the lesion,and right atrial pressure of patients showed significant increase（P＜0.01）.Slight heart dysfunction appeared in 13 cases of patients.After shunting,acute pancreatitis occurred in 3 cases, and 1 patient died of upper gastrointestinal hemorrhage on the 10 d after PSSs.Doppler ultrasonography for IVC and shunt vessels showed：the swollen liver and spleen lessened on 3d after endovascular procedures.The swollen liver lessened 2-7cm （mean 5.5cm）,swollen spleen lessened 3-8cm （mean 5.8cm）, and the time of ascites disappearance was 3-60d （mean 14d）.All the patients were followed up for 1 month to 15 years with an average of 3 years.Restenosis of the distal part of stent was found in 1 patient in 2 years after operation, hepatic vein occlusion occurred in 1 case in 1 year after treatment,hepatocellular carcinoma occurred in 1 patient in 3 years after stent implantation,and 1 patient died of C type hepatitis after 1 year,and 5 out of 6 cases of patients with infertility had babies after 1 year.All patients had no stent migration or occlusion of shunts and the symptoms of portal hypertension were obviously relieved.Conclusions Endovascular treatment guided by Doppler ultrasonography is a convenient,safe,and effective method for BCS.Portosystemic shunts are commended to patients with hepatic venous occlusions.The above mentioned methods provide a feasible and effective means for IVC stenosis and short segment occlusion with hepatic vein occlusion of BCS.
ObjectiveTo compare the efficacy and safety in the treatment of malignant gastric outlet obstruction between gastrojejunostomy (GJ) and self-expandable metallic stent (SEMS) placement.MethodsThe relevant literatures of efficacy and safety of GJ and SEMS placement in the treatment of malignant gastric outlet obstruction were searched in the PubMed, Embase, Cochrane Library, Web of Science, Clinical Trial, VIP, CNKI, Wanfang Data databases.

Currently, transcatheter intervention has emerged as a first-line treatment for coarctation of the aortic. Due to the radiation exposure associated with catheter interventional therapy, there are numerous restrictions, which harms both patients and medical personnel and is dependent on sizable radiation apparatus. Here, we report for the first time a case of echo-guiding percutaneous aortic stent implantation for a 27 years female patient of reproductive age. After discharge, the patient's aortic coarctation pressure decreased to 18 mm Hg, and the surgical results were satisfactory.
