Introducción: La administración de surfactante pulmonar tradicionalmente se realiza mediante un tubo endotraqueal, pero desde hace años existen técnicas menos invasivas como la administración mediante másscara laríngea, aerosolización y cateterización traqueal. Objetivos: Demostrar la evolución de tres neonatos que recibieron surfactante pulmonar mediante una cateterización traqueal y describir la técnica empleada para su administración. Presentación de casos: Se atendieron tres recién nacidos de muy bajo peso al nacer, que ingresaron en la unidad de cuidados intensivos neonatales del Hospital General Docente Iván Portuondo, San Antonio de los Baños, con síndrome de dificultad respiratoria del prematuro. Todos se trataron con surfactante pulmonar exógeno, Surfacen®, el cual se administró mediante cateterización traqueal empleando un catéter umbilical. Se trata de una técnica mínimamente invasiva que se realizó sin dificultades y siempre en el primer intento. Los tres pacientes mostraron mejoría clínica, gasométrica y radiográfica con esta forma de administración y solo uno de ellos tuvo una complicación durante el proceder, que no constituyó una limitante para su realización. Este método permitió mantener una ventilación no invasiva, y fue innecesaria la intubación endotraqueal en los neonatos. Los profesionales encargados de la ejecución de esta técnica recibieron entrenamiento previo. Conclusiones: La administración mínimamente invasiva de surfactante pulmonar resultó un método eficaz con el que se consiguió la resolución total del cuadro de dificultad respiratoria en los neonatos. El procedimiento empleado permitió una administración rápida y segura del Surfacen®(AU)
Introduction: Pulmonary surfactant administration is traditionally performed by endotracheal tube, but for years there have been less invasive techniques such as administration by laryngeal mask, aerosolization and tracheal catheterization. Objectives: To demonstrate the evolution of three neonates who received pulmonary surfactant via tracheal catheterization and to describe the technique used for its administration. Case presentation: Three very low birth weight newborns were attended and admitted to the neonatal intensive care unit of Iván Portuondo General Teaching Hospital, at San Antonio de los Baños municipality, with preterm respiratory distress syndrome. All were treated with exogenous pulmonary surfactant, Surfacen®, which was administered by tracheal catheterization using an umbilical catheter. This is a minimally invasive technique that was performed without difficulty and always on the first attempt. The three patients showed clinical, gasometric and radiographic improvement with this form of administration and only one of them had a complication during the procedure, which did not constitute a limitation for its performance. This method allowed maintaining non-invasive ventilation, and endotracheal intubation was unnecessary in neonates. The professionals in charge of performing this technique received previous training. Conclusions: Minimally invasive administration of pulmonary surfactant was an effective method that achieved total resolution of respiratory distress in neonates. The procedure used allowed rapid and safe administration of Surfacen®(AU)

@#How to effectively repair esophageal fistulas, caused by esophageal perforation, rupture and anastomotic leakage after esophagectomy has always been a key problem for the digestive surgeon. Although there are many clinical treatment methods, the therapeutic effect is still completely unsatisfactory, especially when severe mediastinal purulent cavity infection is associated with the esophageal fistula. In recent years, foreign centers have promoted a new minimally invasive endoscopic treatment technology to repair the esophageal fistula, endoscopic vacuum-assisted closure therapy, with significantly curative effect. In this article, we will review the specific operation, advantages and disadvantages, as well as the clinical efficacy of endoscopic vacuum-assisted closure therapy in treating the esophageal fistulas, to provide a new therapeutic technique for esophageal fistulas and expand the new field of minimally invasive endoscopic therapy.
RESUMO
Objective: To analyze the effectiveness of percutaneous injection of autologous concentrated bone marrow aspirate (cBMA) combined with platelet-rich plasma (PRP) in the treatment of delayed fracture healing. Methods: A prospective, randomized, controlled, single-blind case study was conducted. Between March 2016 and July 2018, 66 patients who met the inclusion and exclusion criteria for delayed fracture healing but had solid internal fixation of the fracture end were randomly divided into control group (31 cases, treated with percutaneous autogenous bone marrow blood injection) and study group (35 cases, treated with percutaneous autogenous cBMA+PRP injection). General data such as gender, age, body mass index, site of delayed fracture healing, length of bone defect at fracture end, and preoperative radiographic union score for tibia (RUST) showed no significant difference between the two groups ( P>0.05). Before injection, Kirschner wire was used in both groups to stimulate the fracture end and cause minor injury. The fracture healing time, treatment cost, and adverse reactions were recorded and compared between the two groups. Visual analogue scale (VAS) score was used to evaluate pain improvement. The tibial RUST score was extended to the tubular bone healing evaluation. Results: No infection of bone marrow puncture needle eyes occurred in both groups. In the control group, local swelling was obvious in 5 cases and pain was aggravated at 1 day after operation in 11 cases. In the study group, postoperative swelling and pain were not obvious, but 2 cases presented local swelling and pain. All of them relieved after symptomatic treatment. Patients in both groups were followed up, the follow-up time of the control group was 16-36 months (mean, 21.8 months), and the study group lasted 14-33 months (mean, 23.2 months). The amount of bone marrow blood was significantly lower in the study group than in the control group ( t=4.610, P=0.000). The degree of postoperative pain in the study group was less than that in the control group, and the treatment cost was higher than that in the control group. But the differences between the two groups in VAS score at 1 day after operation and treatment cost were not significant ( P>0.05). Fracture healing was achieved in 19 cases (61.3%) in the control group and 30 cases (85.7%) in the study group. The difference in fracture healing rate between the two groups was significant ( χ2=5.128, P=0.024). Fracture healing time and RUST score at last follow-up were significantly better in the study group than in the control group ( P<0.05). At last follow-up, RUST scores in both groups were significantly improved when compared with those before operation ( P<0.05). Conclusion: Autogenous cBMA combined with PRP percutaneous injection can provide high concentration of BMSCs and growth factors, and can improve the fracture healing rate and shorten the fracture healing time better than autogenous bone marrow blood injection.
RESUMO
BACKGROUND/AIMS: Acute pancreatitis complicated by walled-off necrosis (WON) is associated with high morbidity and mortality, and if infected, typically necessitates intervention. Clinical outcomes of infected WON have been described as poorer than those of symptomatic sterile WON. With the evolution of minimally invasive therapy, we sought to compare outcomes of infected to symptomatic sterile WON. METHODS: We performed a retrospective cohort study examining patients who were undergoing dual-modality drainage as minimally invasive therapy for WON at a high-volume tertiary pancreatic center. The main outcome measures included mortality with a drain in place, length of hospital stay, admission to intensive care unit, and development of pancreatic fistulae. RESULTS: Of the 211 patients in our analysis, 98 had infected WON. The overall mortality rate was 2.4%. Patients with infected WON trended toward higher mortality although not statistically significant (4.1% vs 0.9%, p=0.19). Patients with infected WON had longer length of hospitalization (29.8 days vs 17.3 days, p<0.01), and developed more spontaneous pancreatic fistulae (23.5% vs 7.8%, p<0.01). Multivariate analysis showed that infected WON was associated with higher odds of spontaneous pancreatic fistula formation (odds ratio, 2.65; 95% confidence interval, 1.20 to 5.85). CONCLUSIONS: This study confirms that infected WON has worse outcomes than sterile WON but also demonstrates that WON, once considered a significant cause of death, can be treated with good outcomes using minimally invasive therapy.

Crown lengthening is one of the most common surgeries in clinical practice. Under the premise of ensuring the biologic width, the adequate crown is exposed by resecting the periodontal soft tissue and (or) hard tissue to meet the prosthodontic and (or) aesthetic requirements. Considering the various advantages of oral laser, such as safe, precise, minimally invasive and comfort, laser has become a promising technology which can be used to improve the traditional crown lengthening. In this review, the principles and characteristics of laser application in crown lengthening, especially in the minimally invasive or flapless crown lengthening will be reviewed. Its pros and cons will also be discussed.

Minimally invasive treatment of symptomatic thyroid nodules is now commonplace. Ethanol ablation (EA) of thyroid cystic nodules has been performed since the 1990s, but there is no global consensus or guideline. Although various limitations of EA have been described, recommendations for practical application are necessary. Therefore, the Task Force Committee of the Korean Society of Thyroid Radiology initiated the present consensus statement and here we provide recommendations for the role of EA in the management of symptomatic thyroid nodules. These recommendations are based on evidence to date from the literature and expert opinion.

@#Objective To explore the practical feasibility of the weaving technique for pectus carinatum. Methods From January 2011 to December 2018, a total of 51 patients with pectus carinatum, including 47 males and 4 females at age of 9-29 (13.7±2.9) years, were applied with minimally invasive waving technique for the correction. The steel plate was inserted through the subcutaneous layer, intercostal space and over the sternal surface under direct thoracoscopic vision. The number of implanted steel plates was determined by the degree of chest wall deformity. The steel plate was removed 2 years after surgery. Results All the operations were successfully completed, the average operation time was 63.9±15.8 min, the amount of bleeding was 19.8±8.8 mL, and the duration of postoperative hospitalization was 4.6±1.6 d. The adverse events included intercostal artery injury (n=2), pneumothorax (n=4), pleural effusion (n=3) and skin rupture (n=1). And there were 29 patients of moderate pain (numerical rating scale 4-6 points) on the first day after surgery, but no patient was asked to remove the steel palate due to intolerable discomfort. All patients were followed up after plate placement. Of the 51 patients, the plates were removed in 37 patients until 2 years after placement, and the duration of postoperative hospitalization was 1.4±0.5 d. After 33 (1-48) months of routine follow-up after the removal of the plate, 22 patients achieved excellent outcomes and 9 patients with good outcomes. Besides, there were 5 patients with fair outcome and 1 patient with poor outcome. No adverse effect was found in growth and development after the steel plate placement. Conclusion Minimally invasive weaving technique is a safe, feasible, effective and individualized operation for pectus carinatum with substantial thoracic reconstruction.
RESUMO
OBJECTIVE: To compare short-, mid-, and long-term follow-up ablation zone volume alterations as well as imaging features on contrast-enhanced computed tomography (CT) after irreversible electroporation (IRE) of primary and secondary liver tumors with findings subsequent to radiofrequency ablation (RFA). MATERIALS AND METHODS: Volume assessment of 39 ablation zones (19 RFA, 20 IRE) after intervention was performed at four time intervals (day 0 [t1; n = 39], day 1–7 [t2; n = 25], day 8–55 [t3; n = 28], after day 55 [t4; n = 23]) on dual-phase CT. Analysis of peripheral rim enhancement was conducted. Lesion's volume decrease relative to the volume at t1 was calculated and statistically analyzed with respect to patient's sex, age, ablation modality (IRE/RFA), and history of platinum-based chemotherapy (PCT). RESULTS: No influence of patient's sex or age on ablation volume was detected. The decrease in ablation zones' volume was significantly larger (p < 0.05 for all time intervals) after IRE (arterial phase, 7.5%; venous phase, 9.7% of initial volume) compared to RFA (arterial phase, 39.6%; venous phase, 45.3% of initial volume). After RFA, significantly smaller decreases in the ablation volumes, in general, were detected in patients treated with PCT in their history (p = 0.004), which was not detected after IRE (p = 0.288). In the arterial phase, peripheral rim enhancement was frequently detected after both IRE and RFA. In the venous phase, rim-enhancement was depicted significantly more often following IRE at t1 and t2 (pt1 = 0.003, pt2 < 0.001). CONCLUSION: As per our analysis, ablation zone volume decreased significantly in a more rapid and more profound manner after IRE. Lesion's remodeling after RFA but not IRE seems to be influenced by PCT, possibly due to the type of cell death induced by the different ablation modalities.

The pancreatic cancer is one of the most common digestive neoplasm with difficult early diagnosis and poor prognosis,which is considered as the most malignant tumor.In reality,patients always have no obvious clinical symptoms before diagnosis,and they often lose the chance of operation because of distant metastases at diagnosis.Currently,gemcitabine-based chemotherapy has became the first choice to patients with locally advanced pancreatic cancer.Nowadays,radiofrequency ablation as a new treatment,is mainly for patients in locally advanced pancreatic cancer with non-metastatic,unresectable lesions,or insensitive to chemotherapy.Due to its minimal invasion and accuration,a large number of preclinical experiments and clinical studies have confirmed that radiofrequency ablation shows its safety and efficacy to locally advanced pancreatic cancer,which becomes more and more popular.This paper aims to discuss the current situation and advancement in radiofrequency ablation treatment of locally advanced pancreatic cancer.
RESUMO
Laryngeal diseases are closely related to the swallowing and speech function of the patients.Protecting and restoring laryngeal function, while curing lesions, is vital to patients′ quality of life.Photodynamic therapy (PDT) is a minimally invasive method which is widely used in the treatment of tumor, precancerous lesions, and inflammatory diseases.In recent years, it has been shown to have a protective effect on normal structures. This article reviews the clinical outcomes of laryngeal diseases treated with PDT since 1990 in order to evaluate its efficacy and significance. The complete remission rate of early-stage laryngeal tumors and precancerous lesions after PDT is 77.6%(249/321), and a promising effect on recurrent laryngeal papillomatosis has been observed thus far. The prolonged adverse effects of the first-generation photosensitizers have limited the application of PDT. With the improvement of photosensitizers and treatment strategies, PDT promises to be a safe, effective, and minimally invasive treatment method for laryngeal diseases.

RESUMO
A new clinic conception, healthy cosmetic management (HCM), was innovated introduced into diagnose and treatment of patients with high caries risk. The priority of HCM should be given to aesthetic restoration of teeth, taking consideration of the conserving of tissue and pulp of teeth and the balance between health and aesthetics, which may reach to the goal of the individual clinic treatment. HCM includes five steps: 1) caries risk assessment; 2) detection of initial caries; 3) digital aesthetic design; 4) minimally invasive therapy; 5) behavior management of caries and doctor-patient communication pattern. In this article, HCM is introduced into two aspects: process management and clinical protocols, followed by the combination of the clinical practice.

The treatment of malignant tumor is one of the world's worst medical problem and is thus a research hotspot. The occur-rence of tumor development follows the molecule→cell→tissue→organ process. In theory, treatment can be achieved at any stage of tumor-growth by inhibition. Minimally invasive technology for treating tumor embodies the following direction of tumor treat-ment:minimally invasive, precise, and efficient. With endoscopy or imaging as a guide, the purpose of minimally invasive therapy is to have a small wound and to control tumor maximally at the tissue and organ level;thus, this therapy mode is the best and most pre-cise. This kind of technology has a good application prospect, even in the case of distant metastasis, and can be used to relieve the symptoms and improving the quality of survival by treating lesions affecting important organ functions. Minimally invasive therapy is a great challenge following the direction of modern medicine. With the development of medical science and technology, the important role of minimally invasive therapy in future tumor therapy is foreseen.
RESUMO
Local ablation has been accepted in many treatment guidelines as a good alternative to curative resection or transplantation for patients with unresectable hepatocellular carcinoma (HCC). The main advantage of local ablative therapy is minimal invasiveness, guaranteeing low morbidity even for the patient with poor hepatic reserve. Furthermore, the therapeutic efficacy of local ablation, especially radiofrequency ablation (RFA), has been shown to be as effective as surgical resection for early-stage (smaller than 3 cm, less than 4 in number) HCC. The long-term outcome after radiofrequency ablation for HCC reported in large series studies were overall survival of 50% to 60% at 5 years and 27 to 32% at 10 years. Major complication rates are 0% to 2.4%. However, controversy remains regarding whether local ablation can replace surgical resection because many retrospective comparative studies have produced conflicting results. Only a well-designed randomized study will be able to clearly answer this long-standing question. During the past decade, many technical advancements in local ablation have been reported, including novel electrodes, thermal protection (i.e., artificial ascites), fusion image guidance, Sonazoid-enhanced ultrasound guidance, and emerging energy sources (i.e., microwaves, High internsity focused ultrasound, Irreversible electroporation). Local ablation is still an evolving technique in the era of minimally invasive treatment for HCC. Many more technical advances are ongoing to enhance the therapeutic efficacy of local ablation. In summary, local ablation will remain a mainstay of non-surgical treatment early stage HCC and play an important role in multidisciplinary approach for HCC management.

RESUMO
Objective:To evaluate the effectiveness of endoscopic minimally invasive treatment for submucosal tumors of the esophagus.Methods:Included in the study were 33 patients with esophageal submucosal tumors,male 23 and female 10 cases,aged 34-85 years(average 51.2).The lesions were removed by means of endoscopic mucosal resection(EMR),or stripping-resection method,i.e.,first stripped by a needle knife and followed by "injection and cut".Results:All the lesions were resected completely by endoscopic minimally invasive methods.Of 33 lesions,15 cases were undertook EMR,and 18 cases were treated by stripping-resection method.Except 5 cases of treatable bleeding,and 6 cases of post-operative substernal pain,no other complications were found.Pathological exam and immunohistochemical study showed that 25 cases were esophageal leiomyoma,3 cases of stromal tumor,2 cases of lipoma,2 cases of haemangioma and 1 case of submucoal cyst.No recurrence was found during the follow-up of 2-30 months. Conclusion:Endoscopic minimally invasive therapy is effective and safe for the treatment of esophageal submucosal tumors.
RESUMO
Objective To evaluate the efficacy, safety and complications of minimally invasive percutaneous radiofrequency ablation(PRFA) therapy for hepatic cavernous hemangioma(HCH). Methods Twelve patients with total 15 HCHs (2.5cm to 9.5cm) were treated by using RF-2000 generator and 10-needle LeVeen electrode percutaneously guided by B-ultrasound. Tumors larger than 3cm were treated by multiple overlapping ablations that encompassed the entire lesions as well as an approximately 0.5cm rim of normal liver tissue. Results The procedures were successful and the patients recovered well without the complications of bleeding or bile leakage after mean 48-month follow up period. Spiral CT scanning showed that the contrast enhancement was disappeared within the lesions or at their periphery in all cases. The mean diameter of the ablated HCHs reduced 68%. Conclusion The results suggested that PRFA therapy was a minimally invasive, simple, safe, and effective approach for treating HCHs in selected patients.
