ABSTRACT

Introducción: La parálisis cordal bilateral en aducción es la segunda causa de estridor congénito y genera una grave obstrucción de la vía aérea, debutando con estridor. La traqueotomía ha sido durante mucho tiempo el gold estándar para el tratamiento de esta afección, no exenta de complicaciones. Existen procedimientos que intentan evitar la traqueotomía, como el split cricoideo anterior posterior endoscópico (SCAPE). Objetivo: Presentar experiencia con SCAPE en pacientes pediátricos como tratamiento alternativo de parálisis cordal bilateral en aducción. Material y Método: Análisis retrospectivo de los resultados quirúrgicos obtenidos en pacientes con parálisis cordal bilateral en aducción tratados con SCAPE entre enero de 2016 y diciembre de 2019 en el Hospital Guillermo Grant Benavente de Concepción, Chile. Resultados: Siete pacientes se sometieron a SCAPE. Todos los pacientes presentaban insuficiencia respiratoria severa, cinco requirieron asistencia ventilatoria mecánica. Seis pacientes tenían el diagnóstico de parálisis cordal bilateral (PCB) congénita y uno PCB secundaria a tumor de tronco cerebral. Cuatro pacientes presentaron comorbilidad de la vía aérea: dos pacientes presentaron estenosis subglótica grado I y dos pacientes presentaron laringomalacia que requirió manejo quirúrgico. Los días promedio de intubación fueron once días. Ningún paciente requirió soporte ventilatorio postoperatorio, sólo un paciente recibió oxigenoterapia nocturna debido a hipoventilación secundaria a lesión de tronco. Ningún paciente ha presentado descompensación respiratoria grave. Un 40% ha recuperado movilidad cordal bilateral. Conclusión: Split cricoideo anteroposterior endoscópico es una alternativa eficaz para tratar el PCB en pacientes pediátricos. Nuestro estudio evidencia que es una alternativa a la traqueotomía, con excelentes resultados y menor morbimortalidad.


Introduction: Bilateral vocal fold paralysis in adduction is the second cause of congenital stridor and generates a serious obstruction of the airway. Tracheostomy has long been the gold standard for the treatment of this condition, but it has inherent complications. There are procedures that try to avoid tracheotomy, such as the endoscopic anterior posterior cricoid split (EAPCS). Aim: Present our experience with EAPCS in pediatric patients as a treatment for bilateral vocal fold paralysis in adduction. Material and Method: Retrospective analysis of the surgical results obtained in patients with bilateral vocal cord paralysis in adduction treated with EAPCS between January 2016 and December 2019 at Guillermo Grant Benavente Hospital in Concepción, Chile. Results: Seven patients underwent EAPCS. All patients had severe respiratory failure, five required mechanical ventilation assistance. Six patients were diagnosed with congenital bilateral cord palsy (BCP) and one BCP secondary to a brainstem tumor. Four patients had airway comorbidity: two patients had grade I subglottic stenosis and two patients had laryngomalacia that required surgical management. The average days of intubation were eleven days. No patient required post op invasive/non-invasive ventilation, only one patient received nocturnal oxygen therapy due to hypoventilation secondary to trunk injury. None of the patients has presented severe respiratory decompensation. Forty percent have recovered bilateral chordal mobility. Conclusion: SCAPE is a cutting-edge and effective alternative to treat PCB in pediatric patients. Our study shows that it is an alternative to tracheotomy, with excellent results and lower morbidity and mortality.

ABSTRACT

ABSTRACT Purpose: One of the most important disadvantages of using Mini Monoka stents in pediatric canalicular laceration repair is premature stent loss. In this study, we aimed to compare clinical outcomes between the use of Mini Monoka and Masterka monocanalicular stents in children and discuss the potential causes of premature stent loss. Methods: The medical records of 36 patients who underwent surgical repair of canalicular lacerations were retrospectively reviewed. Children aged <18 years who underwent canalicular laceration repair with either Mini Monoka or Masterka and had at least 6 months of follow-up after stent removal were included in the study. The patients' demographics, mechanism of injury, type of stent used, premature stent loss, and success rate were analyzed. Success was defined as stent removal without subsequent epiphora and premature stent loss. Results: Twenty-seven children fulfilled our study criteria, and their data were included in the analyses. Mini Monoka was used in 14 patients (51.9%), whereas Masterka was used in 13 patients (48.1%). The preoperative clinical features, including age, sex, and mechanism of injury, were similar between the two groups. The mean age was 8.3 ± 5.5 years in the Mini Monoka group and 7.8 ± 5.9 years in the Masterka group (p=0.61). Three patients in the Mini Monoka group (21.4%) underwent reoperation due to premature stent loss. No premature stent loss was observed in the Masterka group. As a result, the rate of success was 78.6% in the Mini Monoka group, whereas it was 100% in the Masterka group (p=0.22). Conclusions: Even though the two groups did not show any statistically significant difference in success rate, we did not observe any premature stent loss in the Masterka group. Further studies with larger and randomized series are warranted to elaborate on these findings.


RESUMO Objetivo: Uma das desvantagens mais importantes do uso de stents Mini Monoka no reparo de lacerações canaliculares pediátricas é a perda prematura do stent. Neste estudo, objetivamos comparar os resultados clínicos dos stents monocanaliculares Mini Monoka e Masterka em crianças e discutir as possíveis causas da perda prematura do stent. Métodos: Foram incluídos nesta revisão retrospectiva 36 pacientes <18 anos de idade que se submeteram ao reparo cirúrgico de uma laceração canalicular com um stent Mini Monoka ou Masterka e tiveram pelo menos 6 meses de acompanhamento após a remoção do stent. Foram analisados os dados demográficos, o mecanismo da lesão, o tipo de stent utilizado, a ocorrência de perda prematura de stent e o sucesso da intervenção. O sucesso foi definido como a ausência de epífora após a remoção do stent, sem a perda prematura deste. Resultados: Vinte e sete pacientes preencheram os critérios do presente estudo e foram incluídos nas análises. O stent Mini Monoka foi usado em 14 pacientes (51,9%), enquanto o Masterka foi usado em 13 pacientes (48,1%). As características clínicas pré-operatórias, incluindo idade, sexo e mecanismo de lesão, foram semelhantes entre os dois grupos. A média de idade foi de 8,3 ± 5,5 anos no grupo Mini Monoka e de 7,8 ± 5,9 anos no grupo Masterka (p=0,61). Três pacientes do grupo Mini-Monoka (21,4%) tiveram que ser operados novamente por perda prematura do stent. Nenhuma perda prematura do stent foi observada no grupo Masterka. Como resultado, a taxa de sucesso foi de 78,6% no grupo Mini Monoka e de 100% no grupo Masterka (p=0,22). Conclusões: Embora nenhuma diferença estatisticamente significativa tenha sido detectada entre os dois grupos em termos de taxas de sucesso, não observamos nenhuma perda prematura de stent no grupo Masterka. São necessários mais estudos, com séries maiores e randomizadas, para chegar a maiores conclusões sobre esses achados.

ABSTRACT

Objective: To explore the safety and efficacy of excimer laser coronary angioplasty (ELCA) for the treatment of degenerated great saphenous vein graft (SVG). Methods: This is a single-center, prospective, single-arm study. Patients, who were admitted to the Geriatric Cardiovascular Center of Beijing Anzhen Hospital from January 2022 to June 2022, were consecutively enrolled. Inclusion criteria were recurrent chest pain after coronary artery bypass surgery (CABG), and coronary angiography confirmed that the SVG stenosis was more than 70% but not completely occluded, and interventional treatment for SVG lesions was planned. Before balloon dilation and stent placement, ELCA was used to pretreat the lesions. Optical coherence tomography (OCT) examination was performed and postoperative index of microcirculation resistance (IMR) were assessed after stent implantation. The technique success rate and operation success rate were calculated. The technique success was defined as the successful passage of the ELCA system through the lesion. Operation success was defined as the successful placement of a stent at the lesion. The primary evaluation index of the study was IMR immediately after PCI. Secondary evaluation indexes included thrombolysis in myocardial infarction (TIMI) flow grade, corrected TIMI frame count (cTFC), minimal stent area and stent expansion measured by OCT after PCI, and procedural complications (Ⅳa myocardial infarction, no reflow, perforation). Results: A total of 19 patients aged (66.0±5.6) years were enrolled, including 18 males (94.7%). The age of SVG was 8 (6, 11) years. The length of the lesions was greater than 20 mm, and they were all SVG body lesions. The median stenosis degree was 95% (80%, 99%), and the length of the implanted stent was (41.7±16.3)mm. The operation time was 119 (101, 166) minutes, and the cumulative dose was 2 089 (1 378, 3 011)mGy. The diameter of the laser catheter was 1.4 mm, the maximum energy was 60 mJ, and the maximum frequency was 40 Hz. The technique success and the operation success rate were both 100% (19/19). The IMR after stent implantation was 29.22±5.95. The TIMI flow grade of patients after ELCA and stent implantation was significantly improved (all P>0.05), and the TIMI flow grade of all patients after stent implantation was Grade Ⅲ. The cTFC decreased significantly after ELCA (33.2±7.8) and after stent placement (22.8±7.1) than preoperative level (49.7±13.0) (both P<0.001). The minimum stent area was (5.53±1.36)mm2, and the stent expansion rate was (90.0±4.3)%. Perforation, no reflow, type Ⅳa myocardial infarction and other complications were not observed. However, postoperative high-sensitivity troponin level was significantly increased ((67.937±33.839)ng/L vs. (5.316±3.105)ng/L, P<0.001). Conclusion: ELCA is safe and effective in the treatment of SVG lesions and could improve microcirculation and ensure full expansion of stent.

ABSTRACT

OBJECTIVE@#To assess the safety and efficacy of Neuroform Atlas stent used in treatment of unruptured wide-neck intracranial aneurysms.@*METHODS@#Clinical data of 62 patients with unruptured wide-neck intracranial aneurysms undergoing Neuroform Atlas stent-assisted coiling from August 2020 to September 2021 were retrospectively analyzed. There were 64 aneurysms in those 62 patients. Among them, 25 aneurysms were located at the bifurcation of M1 segment on middle cerebral artery, 16 at the anterior communicating artery, 10 at the C7 segment of internal carotid artery, 5 at the C6 segment of internal carotid artery, 4 at the apex of basilar artery, 3 at the A3 segment of anterior cerebral artery, and 1 at the M2 segment of middle cerebral artery. All the patients underwent Neuroform Atlas stent-assisted coiling, including 49 patients with single stent assisted coiling and 15 patients with dual stents assisted coiling (14"Y"style and 1"X"style). After the procedure, the immediate DSA was performed to evaluate the status of aneurysm occlusion and the parent artery patency. The clinical follow-up was performed 3 months after the operation and evaluated based on the modified Rankin Scale(mRS).DSA image was reviewed at 6 months after operation and Raymond grading scale was used to assess the status of aneurysm occlusion and the parent artery patency.@*RESULTS@#A total of 62 patients with 64 aneurysms were all achieved technical success(100%).The immediate post-procedural Raymond scale was assessed, including Raymond Ⅰ in 57 aneurysms(89.1%, 57/64), Raymond Ⅱ in 6 aneurysms(9.3%, 6/64) and Raymond Ⅲ in 1 aneurysm(1.6%, 1/64). The peri-procedural complications rate was 4.8%(3/62), 2 patients developed intraoperative thrombosis and 1 patient suffered from local subarachnoid hemorrhage. Among them, 55 patients obtained 3 months clinical follow-up after operation and all the patients had good outcomes (mRS≤2), 50 patients with 52 aneurysms were followed up with DSA 6 months after operation, including Raymond Ⅰ in 45 aneurysms(86.5%, 45/52), Raymond Ⅱ in 4 aneurysms(7.7%, 4/52) and Raymond Ⅲ in 3 aneurysms(5.8%, 3/52).@*CONCLUSION@#Neuroform Atlas stent for the treatment of unruptured wide-neck intracranial aneurysms has high safety and good efficacy, and has its advantages over other traditional stents.

ABSTRACT

Obstructive colorectal cancer is a common malignant bowel obstruction. Colostomy or colostomy following tumor resection may be the first choice for emergency surgery. The intestinal and systemic conditions of patients undergoing emergency surgery are often poor, and patients need to undergo multiple operations, which increase the surgical risk and economic burden and reduce the quality of life of patients. Poor intraoperative visualization may also affect the radical operation of emergency surgery. Transanal decompression tube (TDT) can rapidly decompress and drain the obstructed bowel, effectively relieve obstruction symptoms, and improve the success rate of primary radical resection. The TDT squeeze the tumor lightly, causing no spread of tumor cells, and is cheap, but the cavity of transanal decompression tube is small and easily blocked, and requires tedious flushing or regular replacement. Self-expanding metallic stents (SEMS) can relieve intestinal obstruction effectively, provide sufficient preparation time for preoperative examination and improvement of nutritional status. By improving patient's tolerance to radical surgery, SEMS might be used as an important treatment strategy choice for obstructive colorectal cancer. However, SEMS may squeeze the tumor, leading to the spread of tumor cells, increase the recurrence rate and metastasis rate, and reduce the survival rate. Moreover, intestinal wall edema still existed during the operation following SEMS, and the rate of ostomy after anastomosis was as high as 34%. We hypothesized that prolonging the interval between stent insertion and surgery to 2 months, with neoadjuvant chemotherapy administered during this interval (SEMS-neoadjuvant chemotherapy strategy), would help improve outcomes. The SEMS-neoadjuvant chemotherapy strategy is a safe, effective, and well tolerated treatment approach with a high laparoscopic resection rate, low stoma formation rate and improvement in the overall survival for patients with left-sided colon cancer obstruction. The patient physical status is improved, the primary tumor is downstaged, and intestinal wall edema is relieved during the relatively longer interval between SEMS placement and surgery. The SEMS-neoadjuvant chemotherapy strategy may be a preferred therapeutic strategy for obstructive left colon cancer.

ABSTRACT

BACKGROUND@#There is still uncertainty regarding whether diabetes mellitus (DM) can adversely affect patients undergoing carotid endarterectomy (CEA) for carotid stenosis. The aim of the study was to assess the adverse impact of DM on patients with carotid stenosis treated by CEA.@*METHODS@#Eligible studies published between 1 January 2000 and 30 March 2023 were selected from the PubMed, EMBASE, Web of Science, CENTRAL, and ClinicalTrials databases. The short-term and long-term outcomes of major adverse events (MAEs), death, stroke, the composite outcomes of death/stroke, and myocardial infarction (MI) were collected to calculate the pooled effect sizes (ESs), 95% confidence intervals (CIs), and prevalence of adverse outcomes. Subgroup analysis by asymptomatic/symptomatic carotid stenosis and insulin/noninsulin-dependent DM was performed.@*RESULTS@#A total of 19 studies (n = 122,003) were included. Regarding the short-term outcomes, DM was associated with increased risks of MAEs (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 5.1%), death/stroke (ES = 1.61, 95% CI: [1.13-2.28], prevalence = 2.3%), stroke (ES = 1.55, 95% CI: [1.16-1.55], prevalence = 3.5%), death (ES = 1.70, 95% CI: [1.25-2.31], prevalence =1.2%), and MI (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 1.4%). DM was associated with increased risks of long-term MAEs (ES = 1.24, 95% CI: [1.04-1.49], prevalence = 12.2%). In the subgroup analysis, DM was associated with an increased risk of short-term MAEs, death/stroke, stroke, and MI in asymptomatic patients undergoing CEA and with only short-term MAEs in the symptomatic patients. Both insulin- and noninsulin-dependent DM patients had an increased risk of short-term and long-term MAEs, and insulin-dependent DM was also associated with the short-term risk of death/stroke, death, and MI.@*CONCLUSIONS@#In patients with carotid stenosis treated by CEA, DM is associated with short-term and long-term MAEs. DM may have a greater impact on adverse outcomes in asymptomatic patients after CEA. Insulin-dependent DM may have a more significant impact on post-CEA adverse outcomes than noninsulin-dependent DM. Whether DM management could reduce the risk of adverse outcomes after CEA requires further investigation.

ABSTRACT

Objective To analyze the risk factors and build a clinical prediction model for hemodynamic depression (HD) after carotid artery stenting (CAS). Methods A total of 116 patients who received CAS in the Department of Vascular Surgery,Drum Tower Clinical College of Nanjing Medical University and the Department of Vascular Surgery,the Affiliated Suqian First People's Hospital of Nanjing Medical University from January 1,2016 to January 1,2022 were included in this study.The patients were assigned into a HD group and a non-HD group.The clinical baseline data and vascular disease characteristics of each group were collected,and multivariate Logistic regression was employed to identify the independent predictors of HD after CAS and build a clinical prediction model.The receiver operating characteristic (ROC) curve was drawn,and the area under the ROC curve (AUC) was calculated to evaluate the predictive performance of the model. Results The HD group had lower proportions of diabetes (P=0.014) and smoking (P=0.037) and higher proportions of hypertension (P=0.031),bilateral CAS (P=0.018),calcified plaque (P=0.001),eccentric plaque (P=0.003),and the distance<1 cm from the minimum lumen level to the carotid bifurcation (P=0.009) than the non-HD group.The age,sex,coronary heart disease,symptomatic carotid artery stenosis,degree of stenosis,and length of lesions had no statistically significant differences between the HD group and the non-HD group (all P>0.05).Based on the above predictive factors,a clinical prediction model was established,which showed the AUC of 0.807 and the 95% CI of 0.730-0.885 (P<0.001).The model demonstrated the sensitivity of 62.7% and the specificity of 87.7% when the best cut-off value of the model score reached 12.5 points. Conclusions Diabetes,smoking,calcified plaque,eccentric plaque,and the distance<1 cm from the minimum lumen level to the carotid bifurcation are independent predictors of HD after CAS.The clinical prediction model built based on the above factors has good performance in predicting the occurrence of HD after CAS.

ABSTRACT

Objective: To summarize the outcomes of different types of pulmonary atresia in neonates treated by ductus arteriosus stenting. Methods: This study was a retrospective cohort study. A total of 19 neonates who had pulmonary atresia treated by ductus arteriosus stenting in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from April 2014 to June 2021 were included. They were divided into the intact ventricular septum (PA-IVS) group and the ventricular septal defect (PA-VSD) group. Ductus arteriosus stents were implanted by different approaches. These children were followed up regularly at the 1, 3, 6, and 12 months after the surgery and annually since then to evaluate the outcome. Independent sample t-test was used for the statistical analysis. Results: There were 12 children in PA-IVS group and 7 in PA-VSD group. All of them were full term in fants. The gestational age of the PA-IVS group and the PA-VSD group was (38.8±1.1) and (37.7±1.8) weeks, the birth weights were (3.2±0.4) and (3.4±1.1) kg, and the age at operation was (10±9) and (12±7) days, respectively, without significant difference (all P>0.05). Among the 12 children with PA-IVS, 9 had stents successfully implanted through the femoral artery and 3 through the femoral vein. Of the 7 children with PA-VSD, 2 had the stents successfully implanted via the femoral artery and 2 failed, and the remaining 3 had stents successfully implanted via the left carotid artery. There was no postoperative thromboembolism, arteriovenous fistula, pseudoaneurysm or other vascular complications. Five children with PA-VSD who had successful operations were followed up at 6 months of age. They all had the operation for pulmonary atresia, repair of the ventricular septal defect, removal of arterial duct stents, and ligation of the arterial duct. All children survived without any stent displacement or stenosis and biventricular circulation was achieved during the follow-up. Conclusions: Ductus arteriosous stenting can be the first-stage treatment for children with PA-IVS and PA-VSD. In addition to the traditional femoral vein and femoral artery approach, the carotid artery can be used as a route for stent placement.

ABSTRACT

Endovascular treatment of Stanford type B aortic dissection (type B dissection) has been widely used. There will be complications such as aortic dilatation, which will lead to poor prognosis of some patients. With more in-depth researches, it was found that there was a possible correlation between the prognosis of type B dissection and tears, such as the increasing of aortic diameter would be faster with longer tears, and the location of the tear will affect the thrombosis of the false lumen. Studies on hemodynamics have also found that different characteristics of tears of aortic dissection can cause changes in the pressure, blood flow rate and blood capacity in the true and false lumens recently. The hemodynamic changes can be used to predict the prognosis of type B dissection. The main characteristics of tears included the size, position, number of tears, residual tears and stent graft induced new entry. Describing the effect of tear characteristics on the development of type B dissection, can provide the basis for the clinical treatment and further research of type B dissection.

ABSTRACT

Isolated superior mesenteric artery dissection (ISMAD) has attracted more and more clinicians' attention in recent years. Patients onset of ISMAD often present with abdominal pain. The misdiagnosis or miss diagnosis is common because of the non-specific symptoms and signs, which even can endanger lives in serious cases. Imaging classification is of great significance for diagnosis and treatment of ISMAD. The Sakamoto classification and the Yun classification are two classical classified methods. However, with the further study of ISMAD, various new classifications emerge. Conservative treatment was once considered as the preferred. As the rapid development of endovascular therapy and the great progress of new devices, stenting therapy can significantly improve symptoms and achieve satisfactory long-term effects, and be even expected to become the preferred method for clinical therapy of ISMAD. However, the long-term effects of endovascular therapy still need a large number of follow-up data, and complications after stent implantation can't be ignored.

ABSTRACT

Objective: To evaluate the protective effect of jailed balloon technique on side branch (SB) ostium using three-dimensional optical coherence tomography(OCT). Methods: This is a retrospective study. Consecutive coronary disease patients with coronary artery bifurcation lesions who underwent percutaneous coronary intervention (PCI) and completed pre-and post-procedural OCT examinations at the Chinese People's Liberation Army General Hospital from September 2019 to March 2022 were enrolled. Patients were divided into the jailed balloon technique group and the unprotected group according to the options applied for the SB. The SB ostium area difference was calculated from OCT images (SB ostium area difference=post-PCI SB ostium area-pre-PCI SB ostium area). The SB ostium area differences were compared between the two groups and compared further in the subgroup of true bifurcation lesions and non-true bifurcation lesions. In the jailed balloon group, the SB ostium area difference was compared between the active jailed balloon technique and the conventional jailed balloon technique, between the jailed balloon>2.0 mm diameter and the jailed balloon≤2.0 mm diameter, and between the higher balloon pressure (>4 atm, 1 atm=101.325 kPa) and the lower balloon pressure (≤4 atm). Multivariate linear regression analysis was used to explore the correlation between the technical parameters of the jailed balloon technique and the SB protection effect. Results: A total of 176 patients with 236 bifurcation lesions were enrolled, aged (60.7±9.3) years, and there were 128 male patients (72.7%). There were 67 patients in the jailed balloon technique group with 71 bifurcation lesions and 123 patients in the unprotected group with 165 bifurcation lesions. Fourteen patients had 2 to 3 lesions, which were treated in different ways, so they appeared in the unprotected group and the jailed balloon technique group at the same time. The area difference in SB ostium was greater in the jailed balloon group than in the unprotected group (0.07 (-0.43, 1.05)mm2 vs.-0.33 (-0.83, 0.26)mm2, P<0.001), and the results were consistent in the true bifurcation lesion subgroup (0.29 (-0.35, 0.96)mm2 vs.-0.26 (-0.64, 0.29)mm2, P=0.004), while the difference between the two groups in the non-true bifurcation lesion subgroup was not statistically significant (P=0.136). In the jailed balloon technique group, the SB ostium area difference was greater in patients treated with the active jailed balloon technique than in those treated with the conventional jailed balloon technique ((0.43±1.36)mm2 vs. (-0.22±0.52)mm2, P=0.013). The difference in SB ostium area was greater in those using>2.0 mm diameter jailed balloons than in those using≤2.0 mm diameter jailed balloons (0.25 (-0.51, 1.31) mm2 vs.-0.01 (-0.45, 0.63) mm2, P=0.020), while SB ostium area difference was similar between those endowed with higher balloon pressure (>4 atm) compared to those with lower balloon pressure (≤4 atm) (P=0.731). Multivariate linear regression analysis showed that there was a positive correlation between jailed balloon diameter and SB ostium area difference (r=0.344, P=0.019). Conclusions: The jailed balloon technique significantly protects SB ostium, especially in patients with true bifurcation lesions. The active jailed balloon technique and larger diameter balloons may provide more protection to the SB.

ABSTRACT

Objective:To evaluate the efficacy of glucocorticoid sinus stents implanted 2 weeks after functional endoscopic sinus surgery(FESS) for the treatment of chronic rhinosinusitis with nasal polyps(CRSwNP). Methods:CRSwNP patients with similar bilateral lesions were randomly divided into two groups, with a stent group of 25 patients and a control group of 24 patients. Patients in the stent group had glucocorticoid sinus stents implanted into the bilateral ethmoid sinuses 2 weeks after FESS, while the control group underwent postoperative debridement only. Follow-up assessments occurred at postoperative weeks 2, 4, 8, and 12. Patients were asked to assess their sensation of nasal symptoms using a 10-point visual analog scale. Efficacy was assessed by endoscopic evaluations. Sinus obstruction, crusting/coagulation, polyp formation, middle turbinate position, adhesions, mucosa epithelialization, and postoperative intervention were assessed as efficacy outcomes. GraphPad Prism 9 was applied for statistical analysis. Results:At 4 and 8 weeks postoperatively, the stent group showed significant improvement in VAS scores of nasal congestion and runny nose compared with the control group(P<0.05). No significant difference was observed in the VAS scores of head and facial stuffiness, loss of smell, or nasal dryness/crusting between the two groups(P>0.05). Compared with the control group, the stent group had a lower rate of polypoid formation at 4, 8, and 12 weeks postoperatively. At postoperative week 12, the rate of mucosal epithelialization in the ethmoid cavity was significantly higher in the stent group. During the follow-up, the frequency of postoperative intervention was significantly lower in the stent group than in the control group(P<0.05). Besides, a lower incidence of middle turbinate lateralization was found in the stent group at 8 and 12 weeks postoperatively. At 8 weeks postoperatively, the stent group had a percentage of adhesion lower than that of the control group(all P<0.05). Conclusion:Implantation of glucocorticoid sinus stents after FESS can maintain sinus cavity patency, improve the inflammatory status of the operative cavity, reduce postoperative interventions, and promote benign regression of the operative cavity.

ABSTRACT

Acute coronary syndrome (ACS) is one of the leading causes of death in cardiovascular disease. Percutaneous coronary intervention (PCI) is an important method for the treatment of coronary heart disease (CHD), and it has greatly reduced the mortality of ACS patients since its application. However, a series of new problems may occur after PCI, such as in-stent restenosis, no-reflow phenomenon, in-stent neoatherosclerosis, late stent thrombosis, myocardial ischemia-reperfusion injury, and malignant ventricular arrhythmias, which result in the occurrence of major adverse cardiac events (MACE) that seriously reduce the postoperative benefit for patients. The inflammatory response is a key mechanism of MACE after PCI. Therefore, examining effective anti-inflammatory therapies after PCI in patients with ACS is a current research focus to reduce the incidence of MACE. The pharmacological mechanism and clinical efficacy of routine Western medicine treatment for the anti-inflammatory treatment of CHD have been verified. Many Chinese medicine (CM) preparations have been widely used in the treatment of CHD. Basic and clinical studies showed that effectiveness of the combination of CM and Western medicine treatments in reducing incidence of MACE after PCI was better than Western medicine treatment alone. The current paper reviewed the potential mechanism of the inflammatory response and occurrence of MACE after PCI in patients with ACS and the research progress of combined Chinese and Western medicine treatments in reducing incidence of MACE. The results provide a theoretical basis for further research and clinical treatment.

ABSTRACT

Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms in men. When drug treatment is ineffective or conventional surgery is not suitable, novel minimally invasive therapies can be considered. These include prostatic urethral lift, prostatic artery embolisation, water vapor thermal therapy, Aquablation-image guided robotic waterjet ablation, temporary implantable nitinol device and prostatic stents. These novel therapies can be performed in outpatient setting under local anesthesia, with shorter operative and recovery times, and better protection of ejaculatory function and erectile function. General conditions of the patient and advantages and disadvantages of the each of these therapies should be fully considered to make individualized plans.

ABSTRACT

Introducción: La persona en postoperatorio de cirugía abdominal puede llegar a presentar complicaciones a causa de la patología quirúrgica de base o por la cirugía, impidiendo iniciar o tolerar la vía oral. Una medida que se toma para prevenir o tratar la desnutrición hospitalaria es el manejo con soporte nutricional artificial, evento que transforma la forma de percibir y vivir el proceso de alimentación. Objetivo: comprender el proceso que vive la persona adulta al recibir soporte nutricional artificial en el postoperatorio de cirugía abdominal. Materiales y métodos: se empleó la metodología cualitativa, teoría fundamentada, según postulados de Corbin y Strauss. Se realizaron entrevistas a profundidad a 21 personas adultas en postoperato-rio de cirugía abdominal y manejo con soporte nutricional artificial. Resultados: del análisis de los datos se establecieron 4 etapas del proceso: presentando dificultad para alimentarse, estando desnutrido o en riesgo nutricional, recibiendo el soporte nutricional artificial y anhelando recu-perar la normalidad de la vida. Conclusiones: el proceso tiene un punto de inicio, determinado por las manifestaciones de la enfermedad, luego el paciente pasa a recibir soporte de nutrición artificial, situación que les genera miedo y ansiedad, continúa con la aceptación y el reconoci-miento de los beneficios de la nutrición artificial y finaliza con el inicio de la vía oral.


Introduction: the person in the postoperative period of abdominal surgery may present com-plications due to the underlying surgical pathology or due to the surgery, preventing them from starting or tolerating the oral route. A measure that is taken to prevent or treat hospital malnutrition is management with artificial nutritional support, an event that transforms the way of perceiving and experiencing the feeding process. Objective: to understand the process experienced by adults receiving artificial nutritional support in the postoperative period of ab-dominal surgery. Materials and methods: qualitative methodology was used, fundamental theory, according to Corbin and Strauss postulates. In-depth interviews were conducted with 21 postoperative adults after abdominal surgery and management with artificial nutritional support. Results: From the analysis of the data, 4 stages of the process were established: pre-senting difficulty feeding, malnourished or at nutritional risk, receiving artificial nutritional support and longing to return to normal life.NConclusions: the process has a starting point, determined by the manifestations of the disease, then the patient begins to receive artificial nutrition support, a situation that generates fear and anxiety, continues with the acceptance and recognition of the benefits of nutrition. artificial and ends with the beginning of the oral route

ABSTRACT

RESUMEN La litiasis vesicular asociada a coledocolitiasis puede tener distintos tratamientos, endoscópicos o quirúrgicos, dependiendo del paciente, el entrenamiento del personal médico y de la disponibilidad de instrumental. Ninguno ha demostrado estar exento de complicaciones. Presentamos dos técnicas tendientes a mejorar los resultados del tratamiento quirúrgico de la coledocolitiasis. Una es la extracción transcística de coledocolitiasis y stent, en pacientes que fueron tratados endoscópicamente por colangitis, tendiente a resolver el problema (la litiasis vesicular, la coledocolitiasis y el stent) en un solo tiempo por cirugía laparoscópica. La segunda es una nueva indicación de una técnica ya descripta, la dilatación papilar anterógrada con balón, utilizada en este caso para disminuir las fugas biliares tras un cierre primario de colédoco.


ABSTRACT Cholelithiasis associated with choledocholithiasis may have different treatments, either by endoscopy or surgery, depending on the patient, level of training of the medical staff and availability of instruments. None of them is free of complications. We report two non-conventional techniques aimed at improving the results of the management of choledocholithiasis. Transcystic removal of common bile duct stones and stent in patients who underwent endoscopic treatment for cholangitis is one of these new techniques to manage cholelithiasis, choledocholithiasis and stent removal in a single procedure through laparoscopy. The second technique is a new indication of a previously described procedure, antegrade balloon papillary dilation to reduce biliary leaks after primary closure of the common bile duct.

ABSTRACT

Antiplatelet therapy and percutaneous coronary intervention are two of the most important interventions in the management of coronary artery disease. In the last 20 years there has been groundbreaking advances in the pharmacotherapy and stent technology. Bleeding is the most feared complication of antiplatelet therapy, mainly due to the increase in major adverse cardiovascular events besides the bleeding itself. Different clinical decision tools have developed with the aim to define which patients have a high ischemic or bleeding risk, thus individualizing treatment.

ABSTRACT

Las infecciones urinarias complicadas, dentro de las cuales se encuentran las asociadas a catéteres, son un hallazgo frecuente de la práctica clínica. Las complicaciones infecciosas después de los procedimientos urológicos son una fuente importante de morbimortalidad y consumen múltiples recursos sanitarios. La colonización bacteriana en el catéter ureteral juega un papel esencial en la patogénesis de la infección, y el uso de profilaxis antimicrobiana en urología es controvertido. El objetivo de nuestro trabajo fue evaluar la utilidad de la profilaxis antibiótica en la extracción del catéter doble J

ABSTRACT

Abstract Endoluminal vacuum therapy (EVAC) is a promising alternative for the endoscopic management of gastrointestinal fistulas or perforations that do not respond to endoscopic procedures using clips and stents or are even refractory to surgical procedures. In this case report, we describe the successful endoscopic closure of an esophagogastric anastomotic fistula using EVAC, connected to a vacuum system through a probe in the cavity, which did not close with clip management given the friability and edema of the peri-wound tissue. In conclusion, it is a successful alternative to treat these complications, which are sometimes difficult to resolve.


Resumen La terapia de vacío endoluminal (Endo-Vac) es una alternativa promisoria en el manejo endoscópico de las fístulas o perforaciones gastrointestinales, que no responden a procedimientos endoscópicos cuando se utilizan técnicas como clips, stents o incluso refractarias a procedimientos quirúrgicos. En este reporte de caso describimos el cierre endoscópico exitoso de una fístula anastomótica esofagogástrica, utilizando la terapia Endo-Vac, conectada a un sistema de vacío mediante una sonda en la cavidad, que no presentó cierre inicial a manejo con clips, dada la friabilidad y el edema del tejido perilesional. Se concluye que esta es una alternativa exitosa en el cierre de estas complicaciones, que en ocasiones son de difícil resolución.
