Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.
Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

ABSTRACT Purpose: This study aims to evaluate the safety and efficacy of ultrasound-guided balloon dilation compared to non-balloon dilation for percutaneous nephrolithotomy (PCNL). Materials and methods: A systematic review and meta-analysis were conducted by searching PubMed, EMBASE, and the Cochrane Library. Results were filtered using predefined inclusion and exclusion criteria as described and meta-analysis was performed using Review Manager 5.4 software. Results: A total of six studies involving 1189 patients who underwent PCNL were included. The meta-analysis results demonstrated that compared to non-balloon dilation, balloon dilation was associated with reduced haemoglobin drop [mean difference (MD) = -0.26, 95% CI = -0.40 ~ -0.12, P = 0.0002], decreased transfusion rate [odds ratio (OR) = 0.47, 95% CI = 0.24 ~ 0.92, P = 0.03], shorter tract establishment time (MD = -1.30, 95% CI = -1.87 ~ -0.72, P < 0.0001) and shorter operation time (MD = -5.23, 95% CI = -10.19 ~ -0.27, P = 0.04). Conclusions: Overall, ultrasound-guided balloon dilatation offered several advantages in PCNL procedures. It facilitated faster access establishment, as evidenced by shorter access creation time. Additionally, it reduced the risk of kidney injury by minimizing postoperative haemoglobin drop and decreasing the need for transfusions. Moreover, it enhanced the efficiency of surgery by reducing the operation time. However, it is important to note that the quality of some included studies was subpar, as they did not adequately control for confounding factors that may affect the outcomes. Therefore, further research is necessary to validate and strengthen these findings.

ObjectiveTo investigate the efficacy， safety， and cost-effectiveness of endoscopic ultrasound （EUS）-guided coil placement combined with tissue adhesive injection in the treatment of gastric varices with spontaneous shunt. MethodsA retrospective analysis was performed for the patients with acute gastric variceal bleeding and spontaneous portosystemic shunt who were hospitalized and received balloon-occluded retrograde transvenous obliteration （BRTO） combined with endoscopic tissue adhesive injection or EUS-guided coil placement combined with tissue adhesive injection in Xiangyang Central Hospital from March 2019 to September 2022. The two surgical procedures were compared in terms of efficacy （technical success rate， 5-day rebleeding rate， 1-year rebleeding rate， and time to rebleeding）， safety （the incidence rate of ectopic embolism， the amount of tissue adhesive used， and the amount of lauromacrogol used）， and cost-effectiveness （hospital costs and length of hospital stay）. The t-test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The Kaplan-Meier method was used to estimate the rebleeding. The chi-square test was used for comparison of categorical data between two groups. ResultsA total of 25 patients received successful EUS-guided coil placement and tissue adhesive injection， with a technical success rate of 100%， a median amount of 2.5 mL tissue adhesive used， a median amount of 11.0 mL lauromacrogol used， a mean length of hospital stay of 14.88±3.21 days， a mean hospital cost of 32 660.00±4 602.07 yuan， and a 5-day rebleeding rate of 0%； among these patients， 2 were lost to follow-up， and 23 patients with complete follow-up data had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 689 days. A total of 14 patients underwent modified BRTO combined with endoscopic tissue adhesive injection， with a technical success rate of 100%； a median amount of 5.0 mL tissue adhesive used during surgery， which was significantly higher than that used in EUS （U=39.000， P<0.001）； a median amount of 10.5 mL lauromacrogol used during surgery； a mean length of hospital stay of 15.38±4.94 days； a mean hospital cost of 57 583.47±18 955.40 yuan， which was significantly higher than that used in EUS （t=-6.310， P<0.001）； a 5-day rebleeding rate of 0%. No patient was lost to follow-up， and all 14 patients had an incidence rate of ectopic embolism of 0% and a median time to rebleeding of 244.50 days， with no significant difference between the two groups （χ2=1.448， P=0.229）. ConclusionEUS-guided coil placement combined with tissue adhesive injection is a relatively safe and effective technique for the treatment of gastric variceal bleeding and has a high technical success rate， a low incidence rate of serious adverse events， and similar efficacy to BRTO， with higher safety and cost-effectiveness.

@#BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) can temporarily control traumatic bleeding. However, its prolonged use potentially leads to ischemia-reperfusion injury (IRI). Partial REBOA (pREBOA) can alleviate ischemic burden; however, its security and effectiveness prior to operative hemorrhage control remains unknown. Hence, we aimed to estimate the efficacy of pREBOA in a swine model of liver injury using an experimental sliding-chamber ballistic gun. METHODS: Twenty Landrace pigs were randomized into control (no aortic occlusion) (n=5), intervention with complete REBOA (cREBOA) (n=5), continuous pREBOA (C-pREBOA) (n=5), and sequential pREBOA (S-pREBOA) (n=5) groups. In the cREBOA and C-pREBOA groups, the balloon was inflated for 60 min. The hemodynamic and laboratory values were compared at various observation time points. Tissue samples immediately after animal euthanasia from the myocardium, liver, kidneys, and duodenum were collected for histological assessment using hematoxylin and eosin staining. RESULTS: Compared with the control group, the survival rate of the REBOA groups was prominently improved (all P<0.05). The total volume of blood loss was markedly lower in the cREBOA group (493.14±127.31 mL) compared with other groups (P<0.01). The pH was significantly lower at 180 min in the cREBOA and S-pREBOA groups (P<0.05). At 120 min, the S-pREBOA group showed higher alanine aminotransferase (P<0.05) but lower blood urea nitrogen compared with the cREBOA group (P<0.05). CONCLUSION: In this trauma model with liver injury, a 60-minute pREBOA resulted in improved survival rate and was effective in maintaining reliable aortic pressure, despite persistent hemorrhage. Extended tolerance time for aortic occlusion in Zone I for non-compressible torso hemorrhage was feasible with both continuous partial and sequential partial measures, and the significant improvement in the severity of acidosis and distal organ injury was observed in the sequential pREBOA.

Objective To investigate the diagnosis and treatment strategy of the portal vein complications in children undergoing split liver transplantation. Methods The clinical data of 88 pediatric recipients who underwent split liver transplantation were retrospectively analyzed. Intraoperative anastomosis at the bifurcating site of the portal vein or donor iliac vein bypass anastomosis was performed depending on the internal diameter and development of the recipient's portal vein. A normalized portal venous blood stream monitoring was performed during the perioperative stage. After operation, heparin sodium was used to bridge warfarin for anticoagulation therapy. After portal vein stenosis or thrombosis was identified with enhanced CT or portography, managements including embolectomy, systemic anticoagulation, interventional thrombus removal, balloon dilatation and/or stenting were performed. Results Among the 88 recipients, a total of 10 children were diagnosed with portal vein complications, of which 4 cases were diagnosed with portal vein stenosis at 1 d, 2 months, 8 months, and 11 months after surgery, and 6 cases were diagnosed with portal vein thrombosis at intraoperative, 2 d, 3 d (n=2), 6 d, and 11 months after surgery, respectively. One patient with portal vein stenosis and one patient with portal vein thrombosis died perioperatively. The fatality related to portal vein complications was 2% (2/88). Of the remaining 8 patients, 1 underwent systemic anticoagulation, 2 underwent portal venous embolectomy, 1 underwent interventional balloon dilatation, and 4 underwent interventional balloon dilatation plus stenting. No portal venous related symptoms were detected during postoperative long term follow up, and the retested portal venous blood stream parameters were normal. Conclusions The normalized intra- and post-operative portal venous blood stream monitoring is a useful tool for the early detection of portal vein complications, the early utilization of useful managements such as intraoperative portal venous embolectomy, interventional balloon dilatation and stenting may effectively treat the portal vein complications, thus minimizing the portal vein complication related graft loss and recipient death.

Conclusion. In the last 8 years, the mortality recorded in the ARGEN-IAM-ST registry has remained at high values despite the high reperfusion rates reported.
Résumé
La hemorragia no compresible de torso continúa siendo unas de las principales causas de mortalidad del paciente víctima de trauma. El control de este tipo de sangrado requiere de procedimientos invasivos como la toracotomía de reanimación, la cual se realiza en el paciente in extremis. La utilización de REBOA se re-introduce desde el 2011, como una forma de oclusión endovascular de la aorta y con el tiempo ya forma parte de los implementos con que cuenta un centro de trauma nivel I. Actualmente REBOA se utiliza dentro del proceso de reanimación, mientras se realiza el control definitivo de un sangrado en el torso, con el fin de aumentar la perfusión de órganos como cerebro y corazón, existiendo dos zonas principales de oclusión a nivel aórtico. Múltiples investigaciones se han realizado para encontrar las indicaciones y beneficios de REBOA dentro de la atención integral de un paciente con trauma grave, estando aun estas en desarrollo. La utilización en un paciente con trauma grave se encuentra protocolizada en diferentes pasos que van desde el acceso arterial hasta el seguimiento de la extremidad post retiro del introductor. Por este último punto, REBOA se encuentra dentro de los implementos importantes de la reanimación, sin embargo, no reemplaza conceptos básicos como atención integral del paciente politraumatizado, control precoz del sangrado y el control de daños resucitativo. Su implementación requiere de un centro altamente protocolizado y con equipos de trauma establecidos con el objetivo de disminuir las complicaciones y optimizar la supervivencia.
Non compressible torso hemorrhage continues to be one of the main causes of mortality in trauma victims. The control of this type of bleeding requires invasive procedures such as resuscitation thoracotomy, that is performed on the patient "in extremis". The use of REBOA has been reintroduced since 2011, as a form of endovascular occlusion of the aorta and over time it is has already part of the implements that a level I trauma center. REBOA is used within the resuscitation process, while definitive control of bleeding in the torso is carried out, in order to increase the perfusion of organs such as the brain and heart, with two main areas of occlusion at the aortic level. Multiple investigations have been carried out to find the indications and benefits of REBOA within the comprehensive care of a patient with severe trauma, and these are still under development. Its use in a patient with severe trauma is protocolized in different steps that go from arterial access to follow-up of the extremity after removal of the sheath. For this last point, REBOA is among the important implements of resuscitation, however, it does not replace basic concepts such as comprehensive care of the polytraumatized patient, early control of bleeding and resuscitative damage control. Its implementation requires a highly protocolized center with established trauma teams with the aim of reducing complications and optimizing survival.
Résumé
A mortalidade materna é inaceitavelmente alta. A hemorragia pós-parto encontra- se na primeira posição no mundo, tendo como principal causa específica a atonia uterina. Eventualmente, as medidas iniciais e a terapia farmacológica não são efetivas no controle do sangramento, impondo a necessidade de tratamentos invasivos, cirúrgicos ou não. Entre esses, o tamponamento uterino com balão requer recursos locais mínimos e não exige treinamento extensivo ou equipamento muito complexo. Entretanto, algumas dificuldades podem ocorrer durante a inserção, infusão ou manutenção do balão na cavidade uterina, com especificidades relacionadas à via de parto. Após o parto vaginal, a dificuldade mais prevalente é o prolapso vaginal do balão. Na cesárea, as principais dificuldades são a inserção e o posicionamento do balão na cavidade uterina, principalmente nas cesáreas eletivas. Este artigo revisa e ilustra as principais dificuldades e especificidades relacionadas ao tamponamento uterino com balões.
Maternal mortality is unacceptably high. Postpartum hemorrhage is ranked first in the world, with the main specific cause being uterine atony. Eventually, initial measures and pharmacological therapy are not effective in controlling bleeding, imposing the need for invasive treatments, surgical or not. Among these, uterine balloon tamponade requires minimal local resources and does not require extensive training or very complex equipment. However, some difficulties may occur during insertion, infusion, or maintenance of the balloon in the uterine cavity, with specificities related to the mode of delivery. After vaginal delivery, the most prevalent difficulty is vaginal balloon prolapse. In cesarean section, the main difficulty is the insertion and positioning of the balloon in the uterine cavity, especially in elective cesarean sections. This article reviews and illustrates the main difficulties and specificities related to uterine balloon tamponade.

Introduction: Liquid-filled intragastric balloons (IGBs) have emerged as a safe and effective option for managing overweight and obesity. However, there is limited information available regarding the implementation of liquid IGBs in individuals with low- and moderate-risk obesity. Objective: The objective of this study was to assess the implementation of liquid IGBs in low- and moderate-risk obese individuals in terms of weight loss, safety, and tolerance at four, six, and twelve months of treatment. Materials and methods: This prospective, descriptive observational study included 109 subjects with low- and moderate-risk obesity (body mass index [BMI] of 30-40 kg/m2), who underwent endoscopic implantation of liquid-filled IGBs. The variables analyzed included sex, age, initial and final weight, percentage of weight loss, and side effects. Results: Out of the 109 subjects, 75.22% were women. The average weight at baseline was 87.22 kg, with an average BMI of 31.59 kg/m2. Three different brands of IGBs were used: Orbera (n=103), Spatz3 (n=3), and Elipse (n=3). The average weight loss showed significant differences when analyzed by months and brands-Ellipse: four months (-4.6 kg), Spatz3: three months (-7 kg), Orbera: six months (15.2 kg), Orbera: twelve months (19.7 kg). The average reduction in BMI achieved was 27.71 kg/m2. The complication rate was 2.75%, with two cases (1.83%) attributed to intolerance (abdominal pain) and one case due to acute appendicitis (0.91%). Conclusions: The findings of this study indicate that liquid-filled IGBs are a safe and effective procedure for managing low- and moderate-risk obesity. A minimum duration of twelve months with an IGB implantation is considered optimal for individuals with low- and moderate-risk obesity.

Materiales y métodos: estudio observacional prospectivo y descriptivo, se incluyeron a 109 sujetos con obesidad de riesgo bajo y moderado (índice de masa corporal [IMC] de 30 a 40 kg/m2), a quienes se les implantó por vía endoscópica un BIG de llenado líquido. Se analizaron las variables de sexo, edad, peso inicial y final, porcentaje de pérdida de peso y efectos secundarios. Resultados: 109 sujetos, 75,22% correspondieron a mujeres, el peso promedio fue de 87,22 kg, con IMC promedio de 31,59 kg/m2. Se usaron tres marcas (Orbera, n: 103; Spatz, 3, n: 3; y Elipse, n: 3). La pérdida de peso promedio presentó diferencias importantes al analizar por meses y marcas: Elipse: 4 meses (-4,6 kg), Spatz 3: 3 meses (-7 kg), Orbera: 6 meses (15,2 kg), Orbera: 12 meses (19,7 kg). Se logró la reducción del IMC promedio a 27,71 kg/m2. La tasa de complicaciones fue del 2,75%, 2 (1,83%) por intolerancia (dolor abdominal) y una por apendicitis aguda (0,91%). Conclusiones: El BIG de llenado líquido es un procedimiento seguro y eficaz. Un período de implantación del BIG de al menos 12 meses se considera óptimo para obesidad de riesgo bajo y moderado.
Résumé
La obesidad es una patología de importancia a nivel mundial porque conlleva a una alta carga de mortalidad y morbilidad. El balón intragástrico representa una técnica no quirúrgica empleada cada vez con más frecuencia para lograr pérdida de peso. Si bien, este se considera un método seguro, se han reportado algunas complicaciones desde náuseas y vómitos, hasta eventos adversos graves, tales como perforación. La pancreatitis aguda constituye una complicación muy rara del balón intragástrico y se atribuye su efecto a la compresión directa que ejerce sobre el páncreas. Presentamos el caso de una paciente mujer de 21 años, quien después de 7 meses de colocación de balón intragástrico, cursó con dolor abdominal, náuseas y vómitos, asociados a elevación de enzimas pancreáticas. Se hizo diagnóstico de pancreatitis aguda y se corroboró compresión de la cola del páncreas mediante estudio tomográfico. Se decidió retiro del balón mediante endoscopía, cursando luego con evolución favorable.
Obesity is a pathology of importance worldwide because it leads to a high burden of mortality and morbidity. The intragastric balloon represents a non-surgical technique used more and more frequently to achieve weight loss. Although this is considered a safe method, some complications have been reported, from nausea and vomiting to serious adverse events, such as perforation. Acute pancreatitis is a very rare complication of the intragastric balloon, and its effect is attributed to the direct compression it exerts on the pancreas. We present the case of a 21-year-old female patient who, after 7 months of intragastric balloon placement, developed abdominal pain, nausea, and vomiting, associated with elevated pancreatic enzymes. A diagnosis of acute pancreatitis was made and compression of the tail of the pancreas was confirmed by tomographic study. It was decided to remove the balloon by endoscopy, which then progressed favorably.
Résumé
Mitral stenosis (MS) is a progressive situation caused by obstruction of blood flow across the mitral valve from the left atrium to the left ventricle. It is one of the most common valvular heart lesions found during pregnancy. The chances of significant maternal and fetal morbidity and mortality are more in the case of severe MS. Balloon mitral valvuloplasty (BMV) is a life-saving procedure in pregnancy instead of surgical correction. We are presenting the case of a 24-week pregnant woman with severe MS. She developed pulmonary edema and had undergone successful BMV which allowed her to tolerate her pregnancy decently. It leads to a decrease in the left atrial pressure as well as pulmonary arterial pressure. The patient underwent normal delivery uneventfully. Antibiotics were used with proper consultation and the patient was treated conservatively with excellent maternal and fetal outcomes. BMV is turns out to be a life-saving therapy for severe MS complicated by pulmonary edema.

Objective:To explore the association between serum high density lipoprotein subtype 3 cholesterol (HDL3-C) levels and the severity and in-stent restenosis of patients with coronary artery disease.Methods:124 patients with coronary artery diseases and 62 healthy controls were included in this clinical case-control retrospective study. Participants were hospitalized from November 2020 to November 2021 at Jinling Hospital, Medical School of Nanjing University were enrolled. Patients with coronary artery disease were as follows: 28 patients with acute coronary syndrome and 96 patients with stable coronary heart disease. Serum HDL3-C levels as well as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were determined. According to the coronary artery angiography results of all patients at the time of admission, Gensini scores were calculated and patients were divided into in-stent restenosis group ( n=22), no in-stent stenosis group ( n=23) and non-stent implantation group ( n=79). The correlation between HDL3-C levels and other parameters was analyzed by Pearson or Spearman correlation analyses. Multivariate Logistic regression analyses were used to determine the impact of HDL3-C on the in-stent restenosis of coronary artery diseases. Results:Compared with controls, serum levels of HDL3-C and HDL-C were significantly decreased in patients with coronary artery diseases (all P<0.05). There was a significantly negative correlation between HDL3-C levels and Gensini scores ( r=-0.201, P=0.043). Among patients with coronary artery disease, serum levels of HDL3C, TC and TG in the in-stent restenosis group were significantly lower than in no in-stent stenosis group as well as than in the non-stent implantation group (all P<0.05). Multivariate Logistic regression analyses showed that after adjusting for age, sex, lipid-lowering drugs and TC, TG, LDLC parameters, HDL3-C ( OR=0.885, 95% CI 0.791-0.990, P=0.033) and HDL-C ( OR=0.018, 95% CI 0.001-0.426, P=0.013) levels were both independently associated with the occurrence of coronary artery disease; only HDL3-C levels (no in-stent stenosis group as the reference: OR=0.833, 95% CI 0.698-0.994, P=0.042; non-stent implantation group as the reference: OR=0.812, 95% CI 0.685-0.963, P=0.017) were independently associated with the presence of in-stent restenosis ( P<0.05). Conclusions:Serum HDL3-C levels are decreased in patients with coronary artery disease, especially in patients with in-stent restenosis. HDL3-C levels are associated with the severity of coronary artery lesions and the presence of in-stent restenosis of coronary arteries.

Objective:To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) after pancreaticoduodenectomy and endoscopic selection strategies.Methods:Clinical data of 34 patients treated with ERCP after pancreaticoduodenectomy at the Endoscopic Center of the First Affiliated Hospital of Air Force Medical University from January 2013 to December 2021 were retrospectively analyzed. The success rates of endoscopic insertion, diagnosis, treatment and ERCP, and the incidence of adverse events were analyzed.Results:Fifty ERCP treatments were performed in 34 patients. The success rates of endoscopic insertion, diagnosis, treatment, and ERCP after pancreaticoduodenectomy were 92.0% (46/50), 93.5% (43/46), 88.4% (38/43) and 76.0% (38/50), respectively. The success rates of ERCP assisted with colonoscope and balloon-assisted enterosocpe were 76.0% (19/25) and 75.0% (18/24), respectively. There were 3 adverse events, including 1 case of anastomotic mucosa tear during surgery, 1 case of cardiopulmonary arrest and 1 case of postoperative cholangitis.Conclusion:ERCP is effective and safe after pancreaticoduodenectomy in general. ERCP assisted with colonoscope and balloon-assisted colonoscope shows similar success rate after pancreaticoduodenectomy.

Objective:To compare the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) assisted with colonoscope and enteroscope in patients with history of Roux-en-Y anastomosis.Methods:A retrospective study was performed on the data of 70 patients who underwent ERCP assisted with standard colonoscope or single balloon enteroscope after Roux-en-Y reconstruction in Hangzhou Hospital Affiliated to Nanjing Medical University from January 2017 to December 2020. Patients were divided into the standard colonoscopy group ( n=43) and the single balloon enteroscopy group ( n=27) according to endoscopy. The success rates of insertion, intubation and ERCP, and incidence of complications were compared. Results:A total of 81 ERCP procedures were performed in 70 patients. The insertion success rates of the standard colonoscopy group and the single balloon enteroscopy group were 91.8% (45/49) and 78.1% (25/32), respectively, showing no significant difference ( χ2=2.04, P=0.153). The success rates of primitive papilla intubation in the two groups were 74.1% (20/27) and 1/6, showing significant difference ( P=0.016). The ERCP success rates of the standard colonoscopy group and the single balloon enteroscopy group were 75.5% (37/49) and 59.4% (19/32), showing no significant difference ( χ2=2.36, P=0.124). The post operative complication incidences of the standard colonoscopy group and the single balloon enteroscopy group were 4.1% (2/49) and 9.4% (3/32), showing no significant difference ( χ2=0.25, P=0.620). Conclusion:ERCP assisted with standard colonoscope and single balloon enteroscope is safe and effective in patients after Roux-en-Y anastomosis. Standard colonoscopic ERCP can become an endoscopy solution for patients with biliary tract disease after Roux-en-Y reconstruction.
Résumé
It is difficult to insert long-term dialysis catheters after severe stenosis or occlusion of the internal jugular vein and innominate vein. We used REcanalisation and balloon-oriented puncture for Re-insertion of dialysis catheter in nonpatent central veins (REBORN) in seven patients with severe central venous lesions, and all patients were inserted with long-term dialysis catheters successfully. None had severe complications such as pneumothorax, hemothorax, or pulmonary embolism during operation. All catheters functioned well after postoperative follow-up of 2 months. REBORN provides a novel approach to establish difficult dialysis pathways.
Résumé
Objective:To summarize the preliminary clinical experience of utilizing ureteral balloon dilation catheter in the treatment of "difficult ureter" during ureteroscopic lithotripsy, and to discuss the efficacy and safety of the technique.Methods:Clinical data of 28 patients (30 sides) with upper urinary tract calculi admitted to Beijing Tsinghua Changgung Hospital Affiliated to Tsinghua University from April 2021 to July 2022 were retrospectively analyzed. There were 23 males (82.1%) and 5 females (17.9%), with age of (51.5±13.6) years. Among the 30 sides, 20 (66.7%) on the left and 10(33.3%) were on the right. Calculi were either located in the renal pelvis or calyxes in 7 sides (23.3%), upper ureter in 17 sides (56.7%), and lower ureter in 6 sides (20.0%). The maximum diameter of the stones was (9.4±4.2)mm, and 23 sides (76.7%) were combined with hydronephrosis before surgery. When "difficult ureter" was encountered during the procedure, that is, it was difficult to insert ureteroscope or ureteral access sheath (UAS) due to small ureteral lumen, balloon catheter was used for dilation in the first stage, in which the balloon diameter was 4 mm on 22 sides and 5mm on 8 sides. The instrument was retrogradely inserted through the working channel of F8 semi-rigid ureteroscope, and the small site of the ureteral lumen was dilated under direct endoscopic view. After a single dilation, the balloon catheter was withdrawn, and the effect of dilation was evaluated by semi-rigid ureteroscopy to determine whether to proceed with the following procedures. The intraoperative data were recorded, including surgical method, stage of "difficult ureter" occurred, site of the small part of the ureter, related data of utilizing ureteral dilatation balloon catheter, grade of ureteral injury after dilatation (according to the 0-4 grading classification of endoscopic ureteral injuries), total operation time, balloon catheter-related adverse events, stone-free rate, and time of removing ureteral stents.Results:Among the 30 sides, 29 (96.7%) had difficulty in the stage of ureteroscope insertion, and 1(3.3%) had difficulty in the stage of UAS insertion. A total of 37 small sites of ureter were involved, including 18 in the intramural segment, 10 in the lower part, 2 in the middle part, and 7 in the upper part. Each site was dilated once with a median time of 3 (0.5, 5.0) minutes and a median maximum balloon pressure of 1 215.9(1 215.9, 1 443.9)kPa[12.0(12.0, 14.3)atm]. There were 28 sites of grade Ⅰ injury, 8 sites of grade Ⅱinjury, and 1 site of grade Ⅲinjury. The total duration of unilateral procedure was (73.4±30.3) min. Ureteroscope or UAS insertion was successful in 28 sides(93.3%) after balloon dilation, and failed in 2 sides(6.7%), both of which were in the stage of inserting ureteroscope and ureteral stent was indwelled for the second-stage procedures. On the first day after surgery, the hemoglobin level was (134.1±12.9)g/L, which was significantly different from the preoperative parameters ( P<0.01), and serum creatinine level was (86.7±23.2)μmol/L, which showed no significant difference from the preoperative one ( P=0.263). The primary stone-free rate was 92.9% (26/28), and the total postoperative complication rate was 13.3% (4/30), including 3 of grade Ⅰ (lateral lower abdominal pain requiring additional analgesic drugs) and 1 of grade Ⅱ (postoperative hematuria requiring intravenous hemostatic drugs). Follow-up was conducted for 3 months. All of the 28 successful sides had their ureteral stents removed before the last follow-up, and the time of removal was (36.9±11.5) days. No hydronephrosis was found in the ipsilateral kidney by ultrasound 3 months after operation. Conclusions:Balloon dilation technique showed good efficacy and safety in the treatment of "difficult ureter" during ureteroscopic lithotripsy.
Résumé
Objective:To investigate the clinical efficacy of trigeminal neuralgia treatment in elderly patients with percutaneous balloon compression assisted by a robotic surgical navigation and positioning planning system.Methods:Eleven elderly patients with trigeminal neuralgia admitted to the Department of Neurosurgery, Beijing Chaoyang Hospital, Capital Medical University between August 2021 and August 2022 were retrospectively analyzed.Three-dimensional time-of-flight magnetic resonance angiography, a three-dimensional fast spin-echo sequence with variable flip angles and thin-slice CT scans were performed before the procedure, and multimodal image fusion was performed by a robot workstation.The volume of Meckel's cave was calculated.Two paths were set up in the surgical planning: an actual puncture path, targeting the anterior inner quadrant of the internal foramen ovale, and a virtual path, used to plan the insertion depth of the balloon.The actual puncture path was completed under the guidance of the robotic arm adapter, and the virtual path for depth measurement was completed under lateral X-ray views of digital subtraction angiography.The balloon was placed at the predetermined depth and was inflated to form a pear shape to complete the procedure.The visual analogue scale(VAS)score was used to evaluate preoperative pain, and the Barrow Neurological Institute(BNI)facial numbness score was used to evaluate postoperative facial numbness.The patients were followed up for 1-12 months and the results were analyzed.Results:In all of the 11 patients, puncturing the foramen ovale and entry into the Meckel's cave were successfully conducted and the balloon was inflated to form a pear shape.Ten patients(90.9%)achieved complete remission immediately after the procedure, and 1 patient had delayed healing at 5 days after the procedure.There were no serious complications related to the procedure.There was no recurrence of pain during the follow-up, and the BNI numbness grading was between 2-3.The ratio between the inflated balloon volume and the preoperative volume of the Meckel's cave was approximately 1.7.Conclusions:Robot-assisted percutaneous balloon compression is safe and effective for the treatment of trigeminal neuralgia in elderly patients.
Résumé
Objective:To evaluate the efficacy of balloon pulmonary angioplasty (BPA) in chronic thromboembolic pulmonary hypertension (CTEPH) using 99Tc m-macroaggregated albumin (MAA) pulmonary perfusion tomography imaging. Methods:Twenty-five patients (4 males, 21 females; age (56.5±12.3) years) with CTEPH who underwent BPA from January 2017 to April 2020 in Beijing Chaoyang Hospital, Capital Medical University were enrolled retrospectively. Effect of BPA on the improvement of pulmonary lobe/pulmonary segment perfusion was analyzed, and the proportions of improved and unimproved pulmonary lobe/pulmonary segment perfusion by BPA were calculated. The percentages of perfusion defect scores (PPDs%) of lung perfusion tomography imaging before BPA and after 4-6 times BPA were compared and analyzed (paired t test). The correlations between PPDs% and mean pulmonary artery pressure (mPAP) before BPA and after BPA were analyzed respectively, and the correlation between decreased percentage of PPDs% and decreased percentage of mPAP after BPA were also analyzed (Pearson correlation analysis). Results:Among 150 lobes of 25 patients, 96.00%(144/150) lobes showed perfusion abnormalities before BPA. After BPA, 11.11%(16/144) showed complete improvement, 57.64%(83/144) showed partial improvement, and 31.25%(45/144) showed no improvement. Among 450 pulmonary segments of 25 patients, 62.44%(281/450) showed perfusion abnormalities before BPA. After BPA, 30.60%(86/281), 37.37%(105/281), 32.03%(90/281) showed complete, partial and no improvement, respectively. The post-BPA PPDs% was significantly lower than that of pre-BPA ((39.08±10.88)% vs (57.88±10.46)%; t=10.40, P<0.001). The post-BPA mPAP was significantly lower than that of pre-BPA ((32.36±10.57) vs (49.08±10.23) mmHg; 1 mmHg=0.133 kPa; t=10.25, P<0.001). There was no significant correlation between PPDs% and mPAP either before BPA ( r=0.01, P=0.953) or after BPA ( r=0.27, P=0.199), but there was a positive correlation between the changes of PPDs% and mPAP ( r=0.40, P=0.045). Conclusions:BPA can significantly improve the pulmonary perfusion and reduce mPAP in CTEPH patients. Pulmonary perfusion tomography imaging can be used to evaluate the efficacy of BPA in CTEPH.
Résumé
Objective:To evaluate the safety and efficacy of drug-coated balloon (DCB) in the treatment of symptomatic intracranial atherosclerotic stenosis.Methods:Forty-nine patients with symptomatic intracranial atherosclerotic stenosis treated with DCB in the People′s Hospital of Zhengzhou University from January 2018 to August 2021 were retrospectively included. The location and number of lesions were as follows: 21 cases of the middle cerebral artery, 11 cases of the intracranial segment of vertebral artery, 12 cases of the basilar artery, and 5 cases of the intracranial segment of internal carotid artery. Pre-dilatation of the lesion with a normal balloon followed by DCB angioplasty. Clinical follow-up (outpatient or telephone) was carried out at 30 days, 3 months, 6 months, and 1 year after the operation. Imaging follow-up was carried out at 6 months postoperatively. The surgical success rate (defined as the proportion of patients with residual stenosis<50% after balloon dilatation), perioperative safety (any strokes, TIA, and deaths within 1 month), stroke recurrence, and restenosis were analyzed.Results:The operation was performed in all patients successfully. The median stenosis level was 80% (75%, 85%) preoperatively and 20% (15%, 30%) at the time after the operation. The success rate of the operation was 91.8% (45/49). Stenting was given in 11 cases (22.4%, 11/49) for severe flow-limiting vascular entrapment, or non-flow-limiting entrapment, owing to the concern of subsequent progression of the entrapment. Three cases (6.1%, 3/49) had significant vascular elastic retraction and implement stent implantation. One patient (2.0%, 1/49) developed symptomatic cerebral infarction during perioperative period, and the symptoms improved after treatment. No fatal or disabling stroke occurred. All patients were followed-up successfully. The median follow-up time was 12 months. Two patients (4.1%, 2/49) had a stroke in the responsible vascular area, and 1 (2.0%, 1/49) patient had a stroke in the non-responsible vascular area. Thirty-eight patients (77.6%, 38/49) had followed-up images. The median follow-up time of postoperative imaging was 6 months. Restenosis occurred in two cases (1 case had symptomatic restenosis), and the incidence of restenosis was 5.3% (2/38).Conclusions:DCB in the treatment of symptomatic intracranial atherosclerotic stenosis has a high technical success rate, good perioperative safety, and low stroke recurrence rate in short-term follow-up, demonstrating the good feasibility, safety, and efficacy of DCB.
