Objective To summarize the experience of sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst under ultrasound guided percutaneous catheter drainage combined with endoscopic technique. Methods The clinical data of 30 patients with aged and high risk pancreatic pseudocyst treated from January 2009 to January 2012 in this hospital were analyzed retrospectively. Results Percutaneous tubes were successfully placed in 30 patients， cystic liquid was sufficiently drained， and the compression symptom of cyst was relieved immediately. After stable disease， 12 patients with communicating cysts were diagnosed by using endoscopic retrograde cholangiopancreatography. Pancreatic duct stents were inserted in 12 patients with communicating cysts for 60-90d （with an average 70d） after endoscopic sphincterectomy and endoscopic pancreatic sphincterectomy. Cysts disappeared in the other 18 cases receiving external drainage with external drainage tubes， the drainage time was 15-90 d with an average 30d. Neither recurrence nor complications were found in all the cases during 12-21 months （with an average 18 months） follow-up. Conclusion Interventional ultrasound combined with endoscopic technique sequentially minimally invasive treatment for aged and high risk symptomatic pancreatic pseudocyst has superiorities in little trauma， fewer complications， and exact effect.
ObjectiveTo investigate the efficacy and safety of percutaneous transhepatic gallbladder drainage (PTGBD) combined with early laparoscopic cholecystectomy (LC) in the treatment of elderly patients with high-risk acute cholecystitis.MethodsThe clinical data of 128 elderly patients with high-risk acute cholecystitis admitted to Department of Hepatobiliary Surgery in Dazhou Central Hospital from January 2015 to January 2019 were retrospectively analyzed. Among them, 62 patients underwent PTGBD combined with early LC treatment (PTGBD+early LC group), 66 patients underwent PTGBD combined with delayed LC treatment (PTGBD+delayed LC group). Comparison was performed on the operative time, intraoperative blood loss, conversion to laparotomy rate, postoperative indwelling time, postoperative hospitalization time, total hospitalization time, and complication.ResultsPTGBD was successfully performed in all patients, and the symptoms were relieved within 72 hours. There was no significant difference in operative time, intraoperative blood loss, conversion to laparotomy rate, postoperative indwelling time, postoperative hospitalization time, and total complication rate between the two groups (P>0.05), but the total hospitalization time of the PTGBD+early LC group was shorter than that of the PTGBD+delayed LC group (P<0.001). There was no second operation and death in both two groups. The 128 patients were followed-up for 2–50 months with a average of 19 months. Results of follow-up after operation showed that the patients did not complain of obvious abdominal pain, abdominal distension, chills, fever, jaundice, and other discomforts.ConclusionsFor elderly patients with high-risk acute cholecystitis, early LC is a safe and effective treatment for patients with good overall condition after PTGBD. It can not only shorten the total hospitalization time, but also significantly shorten the time of tube-taking and improve the quality of life of patients. It has important clinical application value.
ObjectiveTo study the efficacy and safety of early laparoscopic cholecystectomy with percutaneous transhepatic gallbladder drainage (PTGBD) in the treatment of elderly patients with high risk moderate acute cholecystitis.MethodsThe clinical data of 218 elderly patients with high risk moderate acute cholecystitis admitted to Department of Hepatobiliary Surgery in Dazhou Central Hospital from January 2015 to October 2019 were retrospectively analyzed, including 112 cases in the PTGBD combined with early LC sequential treatment group (sequential treatment group) and 106 cases in the emergency LC group. In the sequential treatment group, PTGBD was performed first, and LC was performed 3–5 days later. The emergency LC group was treated with anti infection, antispasmodic, analgesia, and basic disease control immediately after admission, and LC was performed within 24 hours. The operation time, intraoperative blood loss, conversion to laparotomy rate, postoperative catheter retention time, postoperative anal exhaust time, postoperative hospitalization time, hospitalization cost, incidence of incision infection, and incidence of complications above Dindo-Clavien level 2 were compared between the two groups to evaluate their clinical efficacy and safety.ResultsAll patients in the sequential treatment group were successfully treated with PTGBD, and the symptoms were significantly relieved within 72 hours. There were significant differences in the operation time, intraoperative blood loss, conversion to laparotomy rate, postoperative tube retention time, postoperative anal exhaust time, postoperative hospitalization time, incidence of incision infection, and the incidence of complications above Dindo-Clavien level 2 between the two groups (P<0.05), which were all better in the sequential treatment group, but the hospitalization cost of the sequential treatment group was higher than that of the emergency LC group (P<0.05). There were no cases of secondary operation and death in the 2 groups. After symptomatic treatment, the symptoms of all patients were relieved, without severe complications such as biliary injury and obstructive jaundice. All the 218 patients were followed up for 4–61 months, with an average of 35 months. During follow-up period, 7 patients in the sequential treatment group had postoperative complications, and complications were occurred in 13 patients in the emergency LC group.ConclusionPTGBD is the first choice for elderly high risk moderate acute cholecystitis patients with poor systemic condition and high risk of emergency surgery, but it has the disadvantage of relatively high medical cost.
Transcatheter aortic valve replacement (TAVR) has become a common theraputic option for aortic stenosis, but the evidence for precise anatomy for TAVR is accumulating. This paper presents the case of an 71-year-old female patient who had an extremely high risk of coronary obstruction due to both coronary ostia lying too low. The patient underwent TAVR with the help of coronary protection successfully. During the procedure, the patient was protected with wires only for both coronaries. After deployment, angiofluoroscopy suggested that chimney stenting should be applied for left coronary. The whole procedure was unenventful and both coronaries were seen.
ObjectiveTo analyze the relation between ABO blood type and postoperative pathological features of patients with colorectal cancer served by West China Hospital of Sichuan University as a regional center in the current version of Database from Colorectal Cancer (DACCA). MethodsThe data of DACCA was updated on January 5, 2022. According to the screening conditions, the enrolled patients with colorectal cancer were divided into blood type A, B, AB, and O. The differences in the postoperative pathological characteristics of patients with different blood types, such as pathological TNM, T, N, M (pTNM, pT, pN, pM) staging, peripheral nerve involvement, high risk factors, tumor regression grade (TRG), and cancer nodules, were analyzed. ResultsAfter screening, 6 089 data rows were analyzed. The patients involved 2 058 blood type A, 1 469 blood type B, 494 blood type AB, and 2 068 blood type O. The results of statistical analysis showed that: ① There were statistical differences in the overall distribution of pTNM and pM stages among the patients with different blood types (H=11.564, P=0.009; H=7.947, P=0.047), which was reflected in: from the overall distribution trend, the proportion of patients with the four blood types in the same stage was similar, but it could still be seen that patients with blood type AB accounted for the highest proportion in the patients with stage Ⅲ, Ⅳ, M1a, M1b as compared with other blood types. ② There were no statistical differences in the overall distribution of peripheral nerve involvement and TRG in the patients with different blood types (H=3.414, P=0.332; H=1.143, P=0.767). ③ There was statistical difference in the proportion of different grades of high risk factors in the patients with different blood types (H=14.540, P=0.002). Specifically, the proportions of patients with grade 3–5 of high risk factors in the patients with AB blood type were the highest. ④ There was no statistical difference in the proportion of the grade of cancer nodules number in patients with different blood types (H=4.460, P=0.216). ConclusionsFrom results of this study, it is found that there are some differences in pTNM stage, pM stage, and high risk factors of colorectal cancer patients with different blood types, but no differences in pT stage, pN stage, peripheral nerve involvement, TRG, and cancer nodules among different blood types of patients. The influence of blood type on postoperative pathological characteristics of colorectal cancer patients needs to be further explored.
Objective To explore the safety and efficacy of regional citrate anticoagulation in hemoperfusion combined with continuous renal replacement therapy (CRRT). Methods Patients who underwent continuous veno-venous hemodiafiltration tandem hemoperfusion between January 2021 and March 2022 in West China Hospital of Sichuan University were retrospectively enrolled. All patients received double-lumen catheter indwelling through internal jugular vein or femoral vein for vascular access, and were treated with Prismaflex V8.0 CRRT machine, extracorporeal circulation line ST150, and disposable hemoperperfusion device HA380. Four percent sodium citrate was pumped from the arterial end at the rate of 180-200 mL/h. The blood pump rate was 130-150 mL/min, the ratio of dialysis fluid to the dose of replacement fluid was 1∶1, the amount of CRRT treatment agent was 20-35 mL/(kg·h), replacement fluid was added by post-dilution method, and the treatment time of hemoperfusion was 8-10 h. The dialysis treatment completion rate, the cardiopulmonary bypass life, the incidence of coagulation events, and the levels of procalcitonin, C-reactive protein, interleukin-6, etc. were observed. Results A total of 143 cases of treatment were completed in 75 patients, among them, 119 cases were successfully completed and the completion rate of hemoperfusion treatment was 83.2%. The average life of hemoperfusion devices was (8.5±1.5) h. Bleeding or blood clotting occurred in 18.9% of the treatment (27/143), 13 cases had CRRT extracorporeal circulation coagulation, 11 cases had hemoperfusion device coagulation, and 3 cases had gastrointestinal bleeding. The ionic calcium levels after the filter of 93 cases of treatment were maintained around 0.25-0.35 mmol/L, and the peripheral calcium levels were maintained around 1.0-1.1 mmol/L. Compared with that at 0 h, the procalcitonin decreased significantly 72 h after hemoperfusion treatment (P=0.014), while there was no significant change in interleukin-6 or C-reactive protein after 72 h treatment (P>0.05). None of the patients experienced anaphylaxis during treatment. Conclusion In CRRT combined with hemoperfusion, the use of regional citrate anticoagulation results in good cardiopulmonary bypass life, inflammatory mediators clearance, and a lower risk of bleeding.
