Efficacy and safety of conversion of percutaneous cholecystostomy to endoscopic transpapillary gallbladder stenting in high-risk surgical patients

Background:Endoscopic transpapillary gallbladder stenting(ETGBS)has been used as an alternative to percutaneous cholecystostomy in patients with acute cholecystitis who are considered unfit for surgery.However,there are few data on the efficacy and safety of ETGBS replacement of percutaneous cholecystostomy in high-risk surgical patients.This study aimed to evaluate the feasibility,efficacy,and safety of ETGBS to replace percutaneous cholecystostomy in high-risk surgical patients.Methods:This single center retrospective study reviewed the data of patients who attempted ETGBS to replace percutaneous cholecystostomy between January 2017 and September 2019.The technical success,clinical success,adverse events,and stent patency were evaluated.Results:ETGBS was performed in 43 patients(24 male,mean age 80.7±7.4 years)to replace percutaneous cholecystostomy due to high surgical risk.The technical success rate and clinical success rate were 97.7%(42/43)and 90.5%(38/42),respectively.Procedure-related adverse events and stent-related late adverse events occurred in 7.0%(3/43)and 11.6%(5/43),respectively.Of the patients who successfully underwent ETGBS(n=42),only one had recurrent acute cholecystitis during follow-up.The median stent patency was 415 days(interquartile range 240–528 days).Conclusions:ETGBS,as a secondary intervention for the purpose of internalizing gallbladder drainage in patients following placement of a percutaneous cholecystostomy,is safe,effective,and technically feasible.Thus,conversion of percutaneous cholecystostomy to ETGBS may be considered as a viable option in high-risk surgical patients.

Adjustable muscle plication:a new surgical technique for strabismic patients with high risk for anterior segment ischemia

【正】INTRODUCTION Anterior ciliary arteries provide 70%of the vascular supply of the anterior segment.A significant interruption of the vascular flow of these arteries increases the risk for anterior ischemia.Although the frequency of this special condition is low after strabismus surgery(1:13 000)[1],its effects may involve substantial visual problems[2].We report the successful outcome of a new surgical approach for strabismus management in a case of high risk for anterior ischemia.Specifically,we show the correction of the horizontal ocular deviation by means of an adjustable muscle

Transcatheter aortic valve implantation in very elderly patients： immediate results and medium term follow-up

Objective To evaluate immediate transcatheter aortic valve implantation （TAVI） results and medium-term follow-up in very elderly pa- tients with severe and symptomatic aortic stenosis （AS）. Methods This multicenter, observational and prospective study was carried out in three hospitals. We included consecutive very elderly （〉 85 years） patients with severe AS treated by TAVI. The primary endpoint was to evaluate death rotes from any cause at two years. Results The study included 160 consecutive patients with a mean age of 87 ± 2.1 years （range from 85 to 94 years） and a mean logistic EuroSCORE of 18.8% ± 11.2% with 57 （35.6%） patients scoring 〉 20%. Procedural success rate was 97.5%, with 25 （15.6%） patients experiencing acute complications with major bleeding （the most frequent）. Global mortality rate during hospitalization was 8.8% （n = 14） and 30-day mortality rate was 10% （n = 16）. Median follow up period was 252.24± 232.17 days. During the follow-up period, 28 （17.5%） patients died （17 of them due to cardiac causes）. The estimated two year overall and cardiac survival rates using the Kaplan-Meier method were 71% and 86.4%, respectively. Cox proportional hazard regression showed that the variable EuroSCORE ≥ 20 was the unique vari- able associated with overall mortality. Conclusions TAVI is safe and effective in a selected population of very elderly patients. Our findings support the adoption of this new procedure in this complex group of patients.
