A total of 101 patients(101 eyes)diagnosed with chronic dacryocystitis that underwent En-DCR in the ophthalmology department, Renmin Hospital, Hubei University of Medicine from November 2020 to October 2021 were collected. The patients were randomly divided into two groups according to whether they were packed with Nasopore at the end of operation, namely, the packed group(49 eyes)and the non-packed group(52 eyes). The postoperative follow-up was 9 mo, the degree of re-bleeding, discomfort, and postoperative success rate(including anatomical success rate and functional success rate)were compared between the two groups of patients.RESULTS: This study included 94 patients, including 45(45 eyes)and 49(49 eyes)in packed group and non-packed group, respectively. The En-DCR was performed successfully in all patients. Postoperative re-bleeding occurred in 1 eye(2%)in the packed group, and 9 eyes(18%)in the non-packed group(P&#x003C;0.05); postoperative nasal discomfort occurred in 2 cases(4%)in the packed group, and 9 cases(18%)in the non-packed group(P&#x003C;0.05); The success rate of postoperative anatomical success rate was 93%(42/45)in the packed group and 88%(43/49)in the non-packed group(P&#x003E;0.05). The postoperative functional success rate was 89%(40/45)in the packed group and 86%(42/49)in the non-packed group(P&#x003E;0.05). Other complications such as orbital fat prolapse, cerebrospinal fluid leakage, sinusitis, visual impairment and double vision were not observed in all patients during the follow-up.CONCLUSION: Nasal packing absorbable material Nasopore around the anastomosis at the end of En-DCR operation can reduce postoperative re-bleeding and postoperative discomfort of patients, and it has no obvious effect on the postoperative success rate.

Fim de emergências de saúde inacabadas e as redes de cuidados com a síndrome congênita do Zika vírus / The end of unfinished health emergencies and the Congenital Zika Syndrome

Resumo Entendendo que problemas de saúde sempre são inacabadas, este trabalho examina consequências da declaração do fim de uma emergência de saúde sobre práticas de diferentes redes de cuidado interconectadas. Parte da pesquisa "Etnografando Cuidados...", é um estudo de caso qualitativo de três documentos produzidos depois do anúncio do fim da epidemia da síndrome congênita de Zika vírus. Mostra contextos de produção de narrativas envolvendo redes de pesquisadores, gestores/prestadores de serviço, mães e famílias de acometidos e associações de mães e suas perspectivas diferentes sobre o que é cuidado. Análises de uma apresentação para pesquisadores e de um texto de discussão no IPEA questionam a narrativa técnica da celebração do fim da emergência com base em conhecimento e atendimento, sem tomar em conta a importância dos cuidados relacionais e afetivos e políticos (das redes de mães/familiares e de associações), deixando-os invisibilizados. Descreve o processo da elaboração da moção para o Fórum Zika na Pandemia, elencando e sistematizando propostas de ações através de um diálogo explícito entre integrante das diferentes redes para abordar questões inacabadas pós-emergenciais. Sugere que práticas semelhantes de diálogo entre redes possam promover maior inclusão e sensibilidade a cuidados que contribuem para diminuir sofrimento e defender direitos de pessoas que continuam a conviver cotidianamente com uma síndrome ou doença cujas consequências persistem.

Abstract Understanding health problems as always unfinished, this article examines consequences of the declaration of the end of a health emergency on the practice of different and interconnected care networks. As part of the "Action Ethnography on Care…" research project, this is a qualitative case study of three documents produced after the announcement of the end of the Congenital Zika Virus Syndrome epidemic. It shows the contexts of narrative production involving researchers, managers/ public service workers, mothers and families of the ill, and mothers' associations and their different perspectives about what care is. Analyses of a presentation for researchers and of a working paper for the Applied Economics Research Institute (IPEA) question the technical narrative celebrating the end of the emergency based on knowledge and health service without taking into account the relational, affective and political care (of mothers, families and associations), leaving the latter invisible. It describes the process of elaboration of a motion by the Zika Pandemic Forum, listing and systematizing action proposals produced in an explicit dialogue among participants in different care networks to approach unfinished post-emergency questions. It suggests that similar practices of dialogue between networks can promote greater inclusion and sensitivity to care that contribute to reducing suffering and defending the rights of people who continue to live daily with a syndrome or disease whose consequences persist.

Objetivo: Determinar los resultados anatómicos y funcionales en pacientes operados de desprendimiento de retina regmatógeno con técnica de retinopexia neumática. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo con pacientes operados con técnica de retinopexia neumática en el Centro Oftalmológico de Villa Clara entre junio del 2019 y abril del 2023. Resultados: La edad media de los pacientes estudiados fue de 62,1años. Los hombres fueron más afectados que las mujeres (60,6 por ciento). El 57,6 por ciento de los ojos tuvo agudeza visual mejor corregida de movimiento de manos al diagnóstico y el 93,9 por ciento mácula desprendida. En el 66,7 por ciento de las operaciones se utilizó el hexafloruro de azufre como tamponador. Se logró el éxito anatómico con una intervención en el 81,8 por ciento (IC 95 por ciento: 80-83,6 por ciento) de los casos. En estos, se alcanzó el éxito funcional en el 85,2 por ciento (IC 95 por ciento: 83,4 -87 por ciento). Los ojos con éxito anatómico alcanzaron como media una agudeza visual mejor corregida de 0,5 décimas (IC 95 por ciento: 0,2-0,7) y se logró una ganancia media de 0,4 décimas (IC 95 por ciento: 0,3-0,5).

Conclusiones: La retinopexia neumática es una muy buena opción para tratar desprendimientos de retina seleccionados. En pacientes con ninguna o mínima vitreorretinopatía proliferativa, se logran buenos resultados anatómicos y funcionales(AU)

Objective: To determine the anatomical and functional results in patients operated on for rhegmatogenous retinal detachment using the pneumatic retinopexy technique. Methods: A descriptive, longitudinal and prospective study was conducted with patients operated on using the pneumatic retinopexy technique at Centro Oftalmológico, of Villa Clara Province, Cuba, between June 2019 and April 2023. Results: The mean age of the studied patients was 62.1 years. Men were more affected than women (60.6 percent). 57.6 percent of the eyes had best-corrected visual acuity of hand movement at diagnosis and 93.9 percent had detached macula. Sulfur hexafluoride was used as a buffer solution in 66.7 percent of the operations. Anatomical success was achieved with one operation in 81.8 percent (95 percent CI: 80-83.6 percent) of cases. In these, functional success was achieved in 85.2 percent (95 percent CI: 83.4-87 percent). The anatomically successful eyes achieved a mean best-corrected visual acuity of 0.5 tenths (95 percent CI: 0.2-0.7), apart from a mean gain of 0.4 tenths (95 percent CI: 0.3-0.5). The most frequent complication was the persistence of residual subretinal fluid, which occurred more frequently in patients older than 60 years and disappeared, on average, at 55.9 days without the need for treatment. Conclusions: Pneumatic retinopexy is a very good option to treat selected retinal detachments. In patients with no or minimal proliferative vitreoretinopathy, good anatomical and functional results are achieved(AU)

Long-term outcomes of therapeutic corneal transplants performed in a tertiary eye care hospital in South India

Purpose: This study aimed to review the demographics, clinical characteristics, and long?term outcomes of therapeutic penetrating keratoplasty (TPK) performed in a tertiary eye care hospital. Methods: Case records of 149 therapeutic transplants (135 patients) that were performed during the calendar year 2016 were retrospectively analyzed, and outcomes were measured until 3 years of follow?up. Information on demographics, presentation characteristics, keratoplasty indications, offending microbe, and secondary surgical interventions was studied. The final outcome was classified in terms of therapeutic, anatomical, and functional outcomes. Results: The median age of the recipients was 55 years with 61% men. The most common indications for TPK were perforated infectious ulcer (45.9%), nonhealing ulcers (29.9%), and graft infections (17.4%). Fungal etiology was noted in 61.2% and bacterial etiology in 17.4% of the eyes. Therapeutic success was achieved in 130 eyes (89%) at the end of 1 month. Anatomical success was achieved in 130 (98.5%) and 88 patients (86.3%) at the end of 1 and 6 months, respectively. At the 6?month time point, 78 patients (76.5%) attained functional success with vision better than light perception. Three?year follow?up data were available for 23.7% of recipients, of which only 12 patients (37.5%) retained a clear graft either after a primary therapeutic or secondary optical keratoplasty. Conclusion: Therapeutic keratoplasty is highly effective in eradicating infection and providing anatomical integrity. However, timely intervention can aid in achieving the best functional outcome.

Surgical decisions and outcomes of rhegmatogenous retinal detachment during the coronavirus disease 2019 pandemic: Data from a tertiary referral center in Taiwan

Purpose: To assess changes in surgical decisions and outcomes of rhegmatogenous retinal detachment (RRD) during the COVID?19 pandemic at a tertiary center in Taiwan. Methods: Patients undergoing pars plana vitrectomy (PPV) or scleral buckling (SB) for primary RRD during Taiwan’s first wave of domestic COVID?19 cases surge between May and July 2021 (COVID cohort, n = 100) were compared to controls in the closest pre?COVID year, 2019 (pre?COVID cohort, n = 121). Results: The COVID cohort had significantly worse RRD presentation, received more PPV (alone or combined with SB (PPV + SB)) and less SB alone, and had comparable single?surgery anatomic success (SSAS) rates. In patients who underwent PPV, more underwent PPV + SB instead of PPV alone. The decision to combine SB in PPV surgery was significantly affected by the COVID pandemic (odds ratio [OR], 3.1860 [95% confidence interval (CI), 1.1487–8.8361]). However, a shorter duration of symptoms before the first presentation (0.9857 [95% CI, 0.9720–0.9997]) was the only factor related to SSAS, whereas the surgical method had no association. The SSAS rate remained close to or over 90% in patients with a duration of symptoms before surgery ?4 weeks but dropped to 83.3% in patients with duration >4 weeks. Conclusion: During the COVID?19 pandemic, worse RRD presentations led to a shift in preference for PPV over SB alone as the primary surgery. The pandemic affected surgeons’ decision to combine SB during PPV. Nevertheless, SSAS was only associated with the duration of symptoms but not with surgical methods.

Análise das gestações ectópicas íntegras tratadas com o protocolo de dose única de metotrexato / Analysis of unruptured ectopic pregnancies treated with single-dose methotrexate protocol

Objetivo: Avaliar o índice de sucesso do tratamento da gravidez ectópica com o protocolo de dose única do metotrexato e verificar sua correlação com variáveis clínicas e dados dos exames complementares. Métodos: É um estudo epidemiológico observacional, analítico, retrospectivo, de delineamento transversal. Foi realizado de janeiro de 2014 a agosto de 2020 em um hospital público, de ensino, em nível terciário, do Sul do Brasil. Em 73 casos com diagnóstico de gestação ectópica íntegra, foi utilizado o protocolo de dose única de metotrexato intramuscular, com a dose de 50 mg/m2 de superfície corporal. As variáveis do estudo foram relacionadas ao sucesso do tratamento e abordaram as características clínicas na admissão, dos exames complementares e do tratamento realizado. As variáveis foram comparadas por análise de regressão de Poisson. O nível de significância estabelecido foi de p < 0,05. Resultados: O índice de sucesso foi de 83,6%, e em nove casos foi necessária uma segunda dose da medicação. Nível de ß-hCG inicial superior a 5.000 mUI/mL foi relacionado a menor chance de sucesso (odds ratio ajustado de 0,20 [0,05-0,95]). Tamanho da imagem anexial, presença de líquido livre na cavidade abdominal e demais variáveis estudadas não afetaram a chance de sucesso do tratamento. Conclusão: O protocolo de dose única de metotrexato mostrou-se uma opção válida para o tratamento da gestação ectópica íntegra, notadamente quando o nível de ß-hCG inicial é inferior 5.000 mUI/mL.

Objective: The purpose of the present study is to evaluate the success rate of treatment of ectopic pregnancy with the single-dose methotrexate protocol and to verify its correlation with clinical variables and complementary exam data. Methods: This is a retrospective epidemiological observational analytical cross-sectional study. It was carried out from January 2014 to August 2020 in a tertiary level teaching hospital in southern Brazil. In 73 cases with a diagnosis of intact ectopic pregnancy, the intramuscular methotrexate single-dose protocol was applied with a dose of 50 mg/m2 of body surface. The study variables were related to the success of the treatment and addressed the clinical characteristics on admission, the complementary exams and the treatment performed. The variables were compared by Poisson regression analysis. The level of significance was set at p < 0.05. Results: The success rate was 83.6%, and in nine cases a second dose of the medication was necessary. An initial ß-hCG level greater than 5,000 mIU/mL was related to a lower chance of success (adjusted odds ratio of 0.20 [0.05- 0.95]). The size of the adnexal image, the presence of free fluid in the abdominal cavity and other variables studied did not affect the chance of a successful treatment. Conclusion: The methotrexate single-dose protocol proved to be a valid option for the treatment of intact ectopic pregnancy, notably when the initial ß-hCG level is below 5,000 mIU/mL.

Cataract versus combined surgery in pseudoexfoliation glaucoma

Purpose: Pseudoexfoliation glaucoma (XFG) is often associated with a higher rate of intraoperative complications and failure. This study aims to compare the long?term clinical and surgical outcomes of cataract surgery alone versus combined surgery in XFG. This was a retrospective comparative case series. Methods: All patients with XFG who underwent either cataract surgery alone [group 1: either phacoemulsification, PHACO/small?incision cataract surgery (SICS), n = 35] or combined surgery (group 2: phacotrabeculectomy, PHACOT or SICS + trabeculectomy, n = 46) from 2013 to 2018 by a single trained surgeon were screened and recalled for a detailed clinical examination, including Humphrey visual field analysis at 3?monthly intervals for a minimum of 3 years. Surgical success (intraocular pressure, IOP, <21 mm Hg and >6 mm Hg with (qualified success) or without medicines, complete success, survival rates, visual field changes, and need for additional procedures/medicines for IOP control were compared between groups. Results: A total of 81 eyes of 68 patients with XFG were included in this study (groups 1–35 eyes and groups 2–46 eyes each). Both groups achieved 27–40% IOP reduction from preoperative IOP levels, P < 0.001. Surgical success rates were similar in both groups (complete success 66% vs 55%, P = 0.4), qualified success 17% vs 24%, P = 0.8, in groups 1 and 2). Kaplan–Meier analysis showed a marginally better survival rate for group 1, 75% (55–87%), than group 2, 66% (50–78%), at 3 and 5 years which was not significantly different. The number of eyes that progressed at 5 years after surgery (5–6%) was similar in both groups. Conclusion: Cataract surgery can be as effective as combined surgery in XFG eyes with regards to final visual acuity, long?term IOP profile, and visual field progression, and complications/survival rates are comparable between the two procedures.

Efficacy of a biosimilar ranibizumab monotherapy for the treatment of retinopathy of prematurity

Purpose: To evaluate the efficacy of a biosimilar ranibizumab (Razumab) on outcomes of retinopathy of prematurity (ROP) for the first time. Methods: This retrospective study included infants presenting with stage 3+ ROP either in zone 1 or zone 2 posterior or aggressive posterior ROP (APROP). All eligible infants received intravitreal razumab (0.25 mg/0.025 ml) monotherapy. Follow?up was continued monthly till complete retinal vascularization was achieved while retreatment with razumab was given when recurrent neovascularization was noted. In case of no recurrence but incomplete vascularization, laser photocoagulation was done to the residual avascular retina. Results: We included 118 eyes of 59 infants with a median gestational age of 30 weeks and median birth weight of 1250 grams. At presentation, APROP was found in 28 eyes (24%) of 14 babies while stage 3 disease was seen in zone 1 in another 28 eyes (24%) and the remaining 62 eyes (52%) had stage 3 ROP in zone 2 posterior region. Complete resolution of ROP along with complete vascularization was seen in 22 eyes (19%) at a median of 55 days (IQR = 31–56 days) and 42 eyes (35%) showed a recurrent neovascularization at a median of 51 days post razumab (IQR = 42– 55 days). The cumulative incidence of recurrence of neovascularization (21%, 95% CI = 14%–29%) peaked at seven weeks and was significantly higher in eyes with APROP (43%, 95% CI = 27%–63%) compared to eyes without APROP (13.4%, 95%CI, 8%?22%) (P < 0.001). Conclusion: Razumab appears to be safe and effective in treating ROP, with about a third requiring reinjection at seven weeks after the first dose.

Duodenal Papilla Morphology and ERCP Cannulation difficulties, failure and complications in Manila Doctors Hospital, a tertiary private hospital: A cross-sectional study

BACKGROUND/OBJECTIVE@#Different major duodenal papilla morphology pose various challenges of cannulation and development of ERCP complications. These morphologies may guide the endoscopist in his cannulation approach and complication prevention. The aim of this study is to determine the major duodenal papilla morphologies of ERCP patients in Manila Doctors Hospital and their associated cannulation difficulties, failure, and complications. @*METHODS@#This is a retrospective cross-sectional study of 246 ERCPs at the Manila Doctors Hospital from January 2017 to December 2018 with naive duodenal papillae classified according to Watanabe (2019) as follows: oral protrusion (small, regular, large) and papilla pattern (annular, unstructured, longitudinal, isolated, gyrate). Association of papilla morphology with cannulation difficulties, failure, and complications were analyzed using logistic regression.@*RESULTS@#Among protrusions, small oral protrusions were more difficult to cannulate compared to regular (OR 0.493, p=0.017) and large protrusions (OR 0.702, p=0.426). Large protrusions had the highest risk for failed cannulation (OR 2.04, p=0.445). Among papilla patterns, unstructured papilla patterns had the highest risk for difficult (OR 3, p=0.008) and failed cannulation (OR 7.08, p=0.020). Complications developed in 7 in- patients with 3 (1.73%) post-ERCP pancreatitis, 1 (0.58%) post- sphincterotomy bleeding, and 1 (0.58%) cholangitis and 2 (1.16%) mortalities. One had myocardial infarction 2 days post-ERCP and another had septic shock after 2 days despite endoscopic biliary drainage and antibiotics.@*CONCLUSION@#Among protrusions, small oral protrusions had the highest risk for difficult cannulation while large protrusions had the highest risk for failed cannulation. Among papilla patterns, unstructured papilla patterns had the highest risk for difficult and failed cannulation.

Efficacy of endoscopic stenting drainage for hilar biliary malignant obstruction caused by hepatocellular carcinoma / 中华消化内镜杂志

Objective:To evaluate the efficacy of endoscopic stenting drainage for patients with malignant hilar biliary obstruction caused by unresectable hepatocellular carcinoma.Methods:Data of 106 patients with malignant hilar obstruction caused by unresectable hepatocellular carcinoma who received endoscopic stenting drainage in the Third Affiliated Hospital of Naval Medical University from January 2012 to January 2019 were retrospectively analyzed. According to the different stent types, they were divided into the metal stent group (30 cases) and the plastic stent group (76 cases). The observation indexes included clinical success rate, complication incidence, stent patency and overall survival time. The independent predictors for stent patency and overall survival of patients were analyzed by multivariate Cox regression model.Results:The overall clinical success rate was 67.9% (72/106) and the incidence of postoperative cholangitis was 29.2% (31/106). The clinical success rates were 93.3% (28/30) and 57.9% (44/76) ( χ2=12.40, P<0.001), and the incidences of postoperative cholangitis were 13.3% (4/30) and 35.5% (27/76) ( χ2=5.12, P=0.024) in the metal stent group and the plastic stent group, respectively. The median stent patency was 5.2 (95% CI:3.7-6.0) months, and the overall survival time was 3.0 (95% CI:2.5-3.7) months. Multivariate Cox regression analysis showed that hepatic drainage volume <30% was an independent predictor for stent patency ( HR=2.12, 95% CI:1.01-4.46, P=0.048). Bismuth type Ⅳ ( HR=2.06, 95% CI:1.12-3.77, P=0.020), Child-Pugh class C ( HR=4.09, 95% CI: 2.00-8.39, P<0.001) and plastic stent ( HR=1.87, 95% CI:1.21-2.90, P=0.005) were independent predictors for overall survival time. Conclusion:Hepatocellular carcinoma involving the hilar bile duct has a poor prognosis. Compared with plastic stents, metal stents show advantages in clinical success rate and incidence of postoperative cholangitis. Hepatic drainage volume <30% is an independent predictor for stent patency, and Bismuth type Ⅳ, Child-Pugh class C and plastic stent are independent predictors for overall survival time.

Efficacy of endoscopic stent placement for Bismuth type Ⅳ hilar cholangiocarcinoma: a large-scale retrospective study / 中华消化内镜杂志

Objective:To investigate the efficacy of endoscopic stent placement for patients with Bismuth type Ⅳ hilar cholangiocarcinoma.Methods:Data of 229 patients with unresectable Bismuth type Ⅳ hilar cholangiocarcinoma who successfully underwent endoscopic stent placement at the Department of Endoscopy, the Third Affiliated Hospital of Naval Medical University from January 2002 to January 2019 were retrospectively analyzed. Outcomes included clinical success rate, complication incidence, stent patency period and overall survival time. The patency of stents and overall survival time of patients were estimated by using the Kaplan-Meier method. The independent predictors for stent patency and overall survival of patients were analyzed by a multivariate Cox proportional regression model.Results:The overall clinical success rate was 78.2% (179/229). The incidence of early cholangitis after endoscopic retrograde cholangiopancreatography was 20.5% (47/229). The median stent patency and overall survival time were 5.7 (95% CI: 4.8-6.7) months and 5.1 (95% CI: 4.2-6.0) months, respectively. Further multivariate Cox regression analysis showed that metal stent ( P<0.001, HR=0.452, 95% CI: 0.307-0.666) and bilateral stents with bilateral angiography ( P=0.036, HR=0.644, 95% CI: 0.427-0.971) were independent predictors of stent patency; total bilirubin>200 μmol/L ( P=0.001, HR=1.627, 95% CI: 1.208-2.192), metal stent ( P=0.004, HR=0.636, 95% CI: 0.467-0.866) and antitumor therapy ( P<0.001, HR=0.439, 95% CI:0.308-0.626) were independent predictors of overall survival. Conclusion:There is high incidence of cholangitis in patients with unresectable Bismuth type Ⅳ hilar cholangiocarcinoma treated with endoscopic stenting. Longer stent patency can be achieved with metal stent placement and bilateral drainage. In addition, metal stent for drainage and antitumor therapy can also help increase the survival benefit.

Influence of donor and pancreatic characteristics on the success rate of islet isolation / 中华内分泌代谢杂志

Objective:To explore the selection criteria of the donor for islet transplantation of Chinese people by analyzing the correlation between pancreas characteristics and success rate of islets isolation.Methods:Data from 113 cases of human islet isolation were collected. According to the result of islet isolation, the donors were divided into two groups, the success group(IEQ≥250 000, purification≥30%, and viability≥80%), and the failure group(IEQ<250 000, or purification<30%, or viability<80%). The modified Ricordi method was used to digest pancreas tissue, and the continuous density gradient method was performed to purify islets. The islets were identified by staining with the Dithizone(DTZ), the islets were analyzed for cell viability and purity.Results:The donor age in success group was significantly younger than failure group in the range of age eligible for this study( t=2.479, P=0.015). Pearson correlation showed that donor age was positively corelated with islet yield( r=-0.214, P=0.047). There was more fat on the pancreas surface in the successful islet isolation group( z=-2.007, P=0.045). The digestibility( t=2.133, P=0.035) and recovery rate( t=5.912, P=0.001) were elevated in success group. Conclusion:The pancreases from younger donors could obtain the higher-yielding islet, the pancreas with more surface fat or with higher weight was associated with islet isolation success in the scope covered by the inclusion criteria of this study.

Influence of effective liver drainage volume on overall survival in patients with malignant hilar biliary obstruction: a multicenter study / 中华消化内镜杂志

Objective:To investigate the influence of liver drainage volume on overall survival time in patients with unresectable malignant hilar bile duct obstruction.Methods:Data of 633 patients with unresectable malignant hilar bile duct obstruction (BismuthⅡ-Ⅳ) who underwent endoscopic stent drainage in 3 endoscopy centers from January 2002 to May 2019 were retrospectively analyzed. Main observation indicators included clinical success rate, stent patency, overall survival, the effective liver drainage volume, and complication incidence.Results:The clinical success rates of patients with liver drainage volume <30%, 30%-50%, and >50% were 56.8% (25/44), 77.3% (201/260) and 84.2% (277/329) respectively. The incidences of early cholangitis were 31.8% (14/44), 18.8% (49/260) and 16.1% (53/329). The median stent patency time was 4.5 (95% CI: 1.8-7.2) months, 5.6 (95% CI: 5.0-6.2) months and 6.6 (95% CI: 5.2-8.0) months. The overall survival time was 2.4 (95% CI: 1.8-3.0) months, 4.0 (95% CI: 3.4-4.6) months and 4.9 (95% CI:4.4-5.4) months, respectively. The clinical success rate ( χ 2=8.28, P=0.012), median stent patency period ( χ 2=18.87, P=0.015) and overall survival time ( χ 2=6.93, P=0.024) of 30%-50% liver drainage volume group were significantly higher than those of <30% group. Further multivariate cox regression analysis showed that the disease type (hepatocellular carcinoma VS hilar cholangiocarcinoma: HR=1.50, 95% CI:1.18-1.91, P=0.001; gallbladder carcinoma VS hilar cholangiocarcinoma: HR=1.45, 95% CI:1.14-1.85, P=0.002; metastatic cholangiocarcinoma VS hilar cholangiocarcinoma: HR=1.48, 95% CI:1.08-2.04, P=0.015), bilirubin level >200 μmol/L ( HR=1.35, 95% CI:1.14-1.60, P<0.001),metal stents ( HR=0.67, 95% CI:0.56-0.79, P<0.001), liver drainage volume (volume 30%-50% VS <30%: HR=0.64, 95% CI: 0.45-0.90, P=0.010; volume>50% VS <30%: HR=0.58, 95% CI:0.41-0.81, P=0.002) and anti-tumor therapy ( HR=0.51, 95% CI:0.42-0.61, P<0.001) were independent predictors for overall survival time of patients with unresectable malignant hilar bile duct obstruction. Conclusion:When endoscopic stent drainage is performed for patients with unresectable malignant hilar bile duct obstruction, at least 30% liver volume is required for better overall survival. In addition, the use of metal stent drainage and anti-tumor therapy may increase survival benefits.
