Objective To explore the comparative application of phase and diaphragmatic navigation in three-dimensional magnetic resonance cholangiopancreatography(3D-MRCP)thin-layer scanning in elderly patients.Methods A total of 180 elderly patients were scanned by phase and diaphragmatic navigation via Siemens Aera1.5T superconducting MR scanner.The acquired images were reconstructed by 3D reconstruction.The anatomical structure,image quality and disease diagnosis were compared between the phase and diaphragmatic navigation groups.Results In liver of anatomy,the liver of primary bile duct,the superior,middle and inferior extrahepatic bile duct and the gallbladder could be well displayed,and the difference was not statistically significant between the two groups(P＞0.05).The display of pancreatic duct and the liver of secondary bile duct of diaphragmatic navigation was significantly better than those of phase navigation(P＜0.05).In terms of image quality,the excellent rate of diaphragmatic navigation was significantly higher than that of phase navigation,and the difference was statistically significant(P＜0.05).There were no statistically significant differences in the detection rate of pancreatobiliary system diseases,the diagnostic rate of cholelithiasis,common bile duct stones,common bile duct dilatation and pancreatic duct dilatation between the two groups(P＞0.05).Conclusion Diaphragmatic navigation is signifi-cantly better than phase navigation in the display of the anatomical structure of the pancreatic duct,the liver of secondary bile duct,and the excellent rate of image quality.Diaphragmatic navigation is more suitable for thin-layer 3D-MRCP scanning in elderly patients.
ABSTRACT
BACKGROUND:Trunk pressure biofeedback is considered a reliable indicator for assessing core muscle strength.It not only reflects the status of an individual's trunk strength but also has a close relationship with the function of respiratory muscles. OBJECTIVE:To explore the correlation between trunk pressure biofeedback and diaphragmatic function in young adults. METHODS:A total of 80 young adults from Shangrao Normal University,China were enrolled,including 34 males and 46 females,with an average age of(19.83±1.45)years.Diaphragmatic thickness and mobility were measured using a bedside musculoskeletal ultrasound system.Maximum inspiratory pressure was determined using a portable pulmonary function tester.Lumbar and abdominal pressures in prone and supine positions were assessed using a pressure biofeedback device.The degree of correlation between trunk pressure biofeedback and diaphragmatic function was determined using Pearson or Spearman correlation coefficients.A multivariate linear regression analysis was used to determine predictive models for diaphragmatic function. RESULTS AND CONCLUSION:Grouped by sex,age,height,body mass,trunk pressure biofeedback values,diaphragm thickness during quiet inspiration and expiration,diaphragmatic thickening ratio during quiet breathing,diaphragmatic thickness during deep inspiration and expiration,diaphragmatic thickening ratio during deep breathing,diaphragmatic mobility during deep inspiration,and maximum inspiratory pressure were higher in the male group than the female group(all P<0.05).Grouped by physical activity level,trunk pressure biofeedback values and maximum inspiratory pressure were lower in the sedentary group than in the exercise group(both P<0.05).Both anterior and posterior trunk pressure biofeedback were significantly correlated with diaphragmatic thickness during quiet inspiration and expiration,diaphragmatic thickening ratio during quiet breathing,diaphragmatic thickness during deep inspiration and expiration,diaphragmatic thickening ratio during deep breathing,diaphragmatic mobility during deep inspiration,and maximum inspiratory pressure(all P<0.01).Anterior trunk pressure biofeedback entered the predictive model for diaphragmatic thickness during quiet inspiration(F=27.228,P<0.001),during deep inspiration(F=38.615,P<0.001),and along with age for diaphragmatic mobility during deep inspiration(F=15.408,P<0.001).Anterior trunk pressure biofeedback,body mass,and age entered the predictive model for maximum inspiratory pressure(F=22.314,P<0.001).To conclude,there is a strong correlation between trunk pressure biofeedback and diaphragmatic thickness,diaphragmatic mobility,and maximum inspiratory pressure.The rapid and simple measurement of trunk pressure biofeedback can serve as a method for screening the diaphragmatic function in healthy young adults.
ABSTRACT
Objective:To evaluate the predictive value of postnatal esophageal deviation index for clinical outcomes of fetuses with left-sided congenital diaphragmatic hernia (L-CDH).Methods:This retrospective study analyzed the clinical data of 103 neonates with prenatally diagnosed L-CDH who were admitted to Guangzhou Women and Children's Medical Center from January 2016 to February 2023. These patients were divided into the survival group ( n=82) and the death group ( n=21) according to the outcomes, and the extracorporeal membrane oxygenation (ECMO) group ( n=25) and the non-ECMO group ( n=78) according to whether ECMO support was required. Thoracoabdominal X-ray screening was performed on all neonates within 24 h after admission and the esophageal deviation index and cardiac deviation index were calculated. Independent sample t-test or Fisher's exact probability test were used to analyze the differences in general condition and postnatal imaging features between different groups. Receiver operating characteristic (ROC) curve was used to evaluate the value of postnatal imaging features in predicting the prognosis of L-CDH. Results:The esophageal deviation index and the cardiac deviation index of neonates in the survival group were lower than those in the death group [(10.5±5.3)% vs. (18.0±4.5)%, t=－5.47; (37.7±7.1)% vs. (42.8±8.2)%, t=－2.62; both P<0.05], while that were both higher in the ECMO group compared with the non-ECMO group [(18.0±4.3)% vs. (10.1±5.2)%, t=6.34; (42.4±7.9)% vs. (37.6±7.1)%, t=2.63; both P<0.05]. ROC curve showed that the area under the curve (AUC) for predicting the need for ECMO support was 0.879 (95% CI: 0.805-0.953) for esophageal deviation index and 0.712 (95% CI: 0.570-0.854) for cardiac deviation index, with the optimal cut-off values of 11.7% and 41.7%, respectively. The AUC for predicting the survival rate in patients with L-CDH by esophageal deviation index and cardiac deviation index were 0.854 (95% CI: 0.761-0.947) and 0.735 (95% CI: 0.582-0.887), respectively, with the corresponding optimal cut-off values of 15.8% and 41.7%. Conclusion:Postnatal esophageal deviation index is of value in predicting the need for ECMO support and survival rate in patients with L-CDH.
ABSTRACT
@#Objective To compare the clinical efficacy of different surgical approaches for Siewert type Ⅱ adenocarcinoma of esophagogastric junction (AEG). Methods The clinical data of the patients with Siewert type Ⅱ AEG who received sugeries in the Department of Thoracic Surgery of Gansu Provincial People's Hospital from August 2014 to December 2019 were retrospectively analyzed. The patients were divided into two groups according to the surgical approach: a transabdominal group (transabdominal diaphragmatic esophageal hiatus approach) and a combined group (thoracoabdominal combined with right thoracic approach). Perioperative clinical data and postoperative follow-up data were collected to compare the short- and long-term efficacy of the two groups. Results A total of 87 patients were enrolled. There were 48 patients (31 males and 17 females, with an average age of 60.85±8.47 years) in the transabdominal group, and 39 patients (25 males and 14 females, with an average age of 61.13±8.51 years) in the combined group. There was no statistical difference between the two groups in the baseline indicators such as gender, age, tumor size and stage (P>0.05). Compared with the combined group, the operation time, intraoperative blood loss, postoperative bed rest time, postoperative total drainage volume were shorter or less, and the visual analogue scale score on the 3rd day after surgery were lower in the transabdominal group (P<0.05). However, the total number of lymph nodes dissected, the number of thoracic lymph nodes dissected and the number of positive thoracic lymph nodes in the combined group were larger than those in the transabdominal group, and the differences were statistically significant (P=0.001). The median survival time in the combined group and transabdominal group was 25.85 months and 20.86 months, respectively. The 3-year overall survival rate of the combined group was higher than that of the transabdominal group (46.2% vs. 38.9%, χ2=5.995, P=0.014). However, there was no statistical difference between the two groups in the postoperative catheter time, esophageal and gastric resection margin distance, number of abdominal lymph nodes dissected, number of positive abdominal lymph nodes, or incidence of postoperative complications (P>0.05). Conclusion For patients with Siewert type Ⅱ adenocarcinoma of esophagogastric junction, thoracoabdominal combined with right thoracic approach is safe and effective, and has advantages in thoracic lymph node dissection, bringing more benefits to the patients, so it is recommended to be popularized in clinical practice.
ABSTRACT
Objective:To investigate the correlation between diaphragmatic-rapid shallow breathing index (D-RSBI) and lung ultrasound score (LUS) in elderly patients with mechanical ventilation and its predictive value for weaning results.Methods:A retrospective study was conducted. The clinical data of elderly patients (age > 60 years old) with invasive positive pressure ventilation (IPPV) admitted to the department of intensive care unit (ICU) of the First Affiliated Hospital of Jinzhou Medical University from January 2021 to June 2022 were enrolled. According to the outcome of withdrawal, the patients were divided into successful and failed groups. The differences in gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), D-RSBI and LUS before weaning and extubation were compared between the two groups. Pearson correlation was used to analyze the correlation between D-RSBI and LUS. The predictive value of D-RSBI and LUS on weaning results of elderly patients with IPPV was analyzed by receiver operator characteristic curve (ROC curve).Results:A total of 398 elderly patients with IPPV were enrolled, including 300 successful weaning patients and 98 failed weaning patients. There were no significant differences in gender and age between the failed group and successful group [male: 55.1% (54/98) vs. 59.0% (177/300), age (years old): 67.02±5.03 vs. 66.96±4.99, both P > 0.05]. APACHEⅡ score in the failed group was significantly higher than that in the successful group (17.09±3.30 vs. 16.06±3.81, P < 0.05), and the D-RSBI and LUS score before extubation were significantly higher than those in the successful group [D-RSBI (time·min -1·mm -1): 2.19±0.33 vs. 1.60±0.22, LUS: 17.30±3.04 vs. 11.97±3.20, both P < 0.01]. All patients showed a significant positive correlation between D-RSBI and LUS score ( r = 0.406, P = 0.000). ROC curve analysis showed that the area under the curve (AUC) of D-RSBI for predicting weaning outcomes in elderly IPPV patients was 0.920, with a 95% confidence interval (95% CI) of 0.881-0.958 and P = 0.000. When the cut-off value was 1.85 times·min -1·mm -1, the sensitivity was 88.7% and the specificity was 86.7%. The AUC of LUS score for predicting weaning outcome in elderly IPPV patients was 0.875, with a 95% CI of 0.839-0.912 and P = 0.000. When the cut-off value was 14.50, the sensitivity was 75.7% and the specificity was 84.7%. Conclusion:There is a significant correlation between D-RSBI and LUS score in elderly mechanically ventilated patients, both of them can predict weaning outcome in elderly patients with mechanical ventilation.
ABSTRACT
Abstract Ultrasound evaluation of diaphragm function allows the detection of diaphragm dysfunction and the adaptation of ventilatory support in patients admitted to intensive care units. The studied patient had a C3 spinal cord injury. Ultrasound evaluation of diaphragm mobility showed that the patient suffered diaphragm dysfunction. A tracheotomy was indicated, and early ventilatory support was initiated. Ultrasound evaluation of diaphragm function in patients with cervical spinal cord injury is a useful and simple technique. It provides fast and reliable data for the diagnosis of respiratory insufficiency of neuromuscular origin.

Materiales y métodos: Se reporta el caso de un feto de 28 semanas en el que se observó imagen ecográfica sugestiva de masa en hemitórax derecho que desplazaba corazón y pulmón; se confirmó que correspondía a un riñón intratorácico. Por laparoscopia, al recién nacido se le colocó una malla en continuidad con el diafragma dejando el riñón en el abdomen, con buena evolución. Se realizó una búsqueda bibliográfica en PubMed, Embase y Cochrane. Se buscaron cohortes, reportes y series de caso de gestaciones con diagnóstico prenatal de riñón intratorácico fetal. Se extrajo información del diseño, la población, el diagnóstico por imágenes, el tratamiento y el pronóstico. Resultados: En la búsqueda se identificaron 8 estudios que cumplieron con los criterios de inclusión y que informan en total ocho casos. El diagnóstico ecográfico mostró REI asociado a hernia diafragmática en todos los sujetos. Se utilizó también la RM fetal en cinco casos. Seis neonatos sobrevivieron sin complicaciones, en uno hubo interrupción voluntaria del embarazo, y otro presentó sepsis y dificultad respiratoria, finalmente fue dado de alta en buenas condiciones. Conclusiones: El REI es una anomalía congénita susceptible de diagnóstico prenatal. La sobrevida a la cirugía correctora en el periodo neonatal es frecuente. La literatura disponible en torno al diagnóstico prenatal de REI es escasa y se limita a reportes de casos.
Objectives: To report a case of prenatal diagnosis of ectopic intrathoracic kidney with diaphragmatic hernia managed surgically after birth, and to conduct a review of the literature on prenatal diagnosis of ectopic intrathoracic kidney and perinatal prognosis. Material and methods: We report the case of a 28-week fetus in which, on ultrasound imaging, a mass was observed displacing the heart and lung in the right hemithorax, which was was confirmed by magnetic resonance (MR) to be an ectopic intrathoracic kidney. After birth, the neonate was approached by laparoscopy to place a mesh in continuity with the diaphragm, leaving the kidney in the abdomen, with good evolution. A search was conducted in the PubMed, Embase and Cochrane databases for cohorts, case reports and case series of prenatal diagnosis of intrathoracic kidney in the fetus. Information was retrieved regarding design, population, imaging diagnosis, treatment and prognosis. Results: The search identified 8 studies that met the inclusion criteria, reporting a total of 8 cases. Ultrasound diagnosis showed ectopic intrathoracic kidney associated with diaphragmatic hernia in all the subjects. Fetal magnetic resonance imaging (MRI) was also used in 5 cases. Conclusions: Ectopic intrathoracic kidney is a congenital abnormality amenable to prenatal diagnosis. Survival after corrective surgery performed in the neonatal period is common. There is a paucity of publications, limited to case reports, regarding the prenatal diagnosis of this condition.

Resumen Una hernia diafragmática congénita ocurre cuando existe un defecto estructural en el diafragma que permite la migración de los órganos abdominales a la cavidad torácica. Se considera de presentación tardía cuando se diagnostica después de los 30 días de vida extrauterina. Más del 60% de los pacientes con hernia diafragmática congénita cuentan con un diagnóstico erróneo al momento del nacimiento, encontrándose dentro de los diagnósticos más frecuentes al derrame pleural, neumonía, neumotórax, neumatocele y absceso pulmonar. Presentamos el caso de una paciente del sexo femenino de 3 años que acudió a urgencias por dolor abdominal, náuseas, vómito, intolerancia a la vía oral y dificultad respiratoria. La radiografía de tórax evidenció migración de la cámara gástrica hacia el tórax, dessplazamiento de la silueta cardiaca y las estructuras del mediastino hacia la derecha con la punta de la sonda nasogástrica ubicada en el hemitórax izquierdo. Se concluyó el diagnóstico de hernia diafragmática de presentación tardía. La paciente recibió tratamiento quirúrgico, el cual fue exitoso. Este trabajo destaca la importancia de sospechar el diagnóstico de hernia diafragmática congénita de presentación tardía cuando se abordan pacientes pediátricos con dificultad respiratoria sin otra causa aparente, dolor abdominal, náuseas y vómito.
Abstract A congenital diaphragmatic hernia occurs when the diaphragm has a structural defect that allows the migration of abdominal organs into the chest cavity. It is called late presentation when its diagnosis does after 30 days of life. More than 60% of patients with congenital diaphragmatic hernia are misdiagnosed. The most common misdiagnoses are pleural effusion, pneumonia, pneumothorax, pneuma tocele, and lung abscess. We present a case of a 3-year-old female who attended the emergency room due to abdominal pain, nausea, vomiting, intolerance to the oral route, and respiratory distress. The chest X-ray showed migration of the gastric chamber towards the thorax, displacement of the cardiac silhouette and the mediastinal structures to the right, and the tip of the nasogastric tube located in the left hemithorax. The doctors concluded a late presentation diaphragmatic hernia. The patient received surgical treatment, which was successful. This paper highlights the importance of suspecting the diagnosis of late-onset congenital diaphragmatic hernia when treating pediatric patients with respiratory distress without another apparent cause, abdominal pain, nausea, and vomiting.
ABSTRACT
Objectives: This study aimed to evaluate diaphragm thickness (DT) and diaphragmatic thickening fraction (DTF) in mechanically ventilated children, and study the association of these measurements with extubation success. Methods: Consecutive children aged one month to 18 years, who required mechanical ventilation (MV) for more than 24 hours at our institution, were enrolled between April, 2019 to October, 2020. Ultrasonographic measurements of DT were documented, and DTF was calculated from baseline (within 24 hours of MV) until 14 days of MV, and up to three days post-extubation. Results: Of the 54 childrenenrolled, 40 underwent planned extubation trial, of which 9 (22.5%) had extubation failure. Pre-extubation and post-extubation DTF between children in extubation-success and extubation-failure groups were comparable (P=0.074). There was no significant difference in the diaphragm atrophy rate between the two groups (P=0.819). Binary logistic regression showed significantly decreased probability of successful extubation with total ventilation duration (P=0.012) and mean DTF% before extubation (P=0.033). Conclusion: Despite evidence of diaphragmatic atrophy in critically ill children receiving mechanical ventilation, there was no significant difference in DTF between extubation success and failure groups.

Objective To study the effects of pressure controlled ventilation(PCV)and volume controlled ventilation(VCV)on diaphragm function and the incidence of postoperative pulmonary complica-tions(PPCs)in patients undergoing laparoscopic surgery.Methods Sixty-six patients underwent laparo-scopic gynecological surgery under general anesthesia,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ were recruited.The patients were randomly divided into two groups:PCV group(group P)and VCV group(group V),33 cases in each group.All the patients were ventilated in VCV mode after induction.Group P was switched to PCV after pneumoperitoneum and group V maintained VCV until the end of operation after pneumoperitoneum.The diaphragm ultrasonic evaluation indexes including di-aphragmatic excursion(DE),diaphragm contraction velocity(DCV),and diaphragmatic rapid shallow breathing index(D-RSBI)were recorded before anesthesia induction,immediately after extubation,and 30 minutes after extubation.The mechanical ventilation time,artificial pneumoperitoneum time,the time from the end of artificial pneumoperitoneum to extubation,the cumulative dosage of cisatracuriumbesylate,and the patient's observer's assessment alert/sedation(OAA/S)immediately after extubation,the incidence of diaphragm dysfunction immediately after extubation and 30 minutes after extubation,and the cumulative in-cidence of PPCs in 1-3 days after operation.Results Compared with group V,DE in group P was in-creased significantly immediately after extubation(P＜0.05),but there was no significant difference in DE of 30 minutes between the two groups after extubation.Compared with group V,DCV in group P was in-creased significantly immediately after extubation and 30 minutes after extubation(P＜0.05),the inci-dence of PPCs in group P was significantly lower on the 1st day after operation(P＜0.05).There were no significant differences in D-RSBI,time of mechanical ventilation,time of artificial pneumoperitoneum,time from the end of pneumoperitoneum to extubation,cumulative dosage of atracurium besylate,OAA/S score immediately after extubation,and the incidence of diaphragm dysfunction immediately after extubation and 30 minutes after extubation,and the cumulative incidence of PPCs on the 2nd and 3rd day after operation.Conclusion In lower abdominal endoscopic gynecological surgery,compared with volume-controlled venti-lation mode,pressure-controlled ventilation mode dose not reduce the incidence of postoperative diaphragm dysfunction,but dose alleviate the weakening of diaphragm inspiratory force and reduce the incidence of pul-monary complications on the first day after operation.
ABSTRACT
Objective:To investigate the clinical features and management of right-sided congenital diaphragmatic hernia (RCDH) with hepatopulmonary fusion (HPF).Methods:This retrospective study analyzed the clinical characteristics of three cases of RCDH complicated by HPF that were treated in Guangzhou Women and Children's Medical Center from June to December 2022. Diaphragm defects in the three cases were classified according to the international standard of diaphragm defect classification. Besides, an extensive search of publications was performed including domestic and foreign databases, including CNKI, Wanfang Database, Yiigle, VIP Chinese journals, PubMed, Embase and UpToDate databases from January 1997 to April 2023 using terms including "congenital diaphragmatic hernia" and "hepatopulmonary fusion". Clinical features and prognosis of RCDH complicated by HPF were summarized.Results:(1) Cases in the present study: RCDH was found in case 1 and case 2 during routine prenatal ultrasound examination; antenatal fetal MRI showed partial displacement of the hepatocele into the right hemithorax, right lung hypoplasia, a normal-sized left lung and without left shift of the mediastinum in both cases. Postnatal chest radiographs of case 1 and case 3 showed dense shadow in the left lung and mediastinum shifted to the right. Case 2 had a D-type defect and a slight shift of the mediastinum to the left was observed on the postnatal chest radiograph. Preoperative imaging findings indicated highly suspected HPF in the three cases. Case 1 and case 2 had complete separation of liver and lung and underwent diaphragmatic herniorrhaphy with patch. Partial lung resection was performed in case 2. Both case 1 and case 2 survived (length of hospital stay was 22 d and 23 d, respectively). Case 3 did not undergo hepatopulmonary separation or herniorrhaphy after exploratory operation and died of persistent pulmonary hypertension. (2) Literature review: Only 40 cases of CDH with HPF were retrieved from PubMed. Among the 43 cases including the above three cases, 27 (62.8%) had a right shift or no deviation of the mediastinum before surgery and nine (20.9%) had a left shift of the mediastinum, while the condition of seven patients (16.3%) were not described. There were 26 patients undergoing complete separation of liver and lung and 19 (73.1%) of them survived. Thirteen patients underwent partial separation of liver and lung and six of them survived. Four patients died without receiving separation.Conclusions:HPF should be considered in patients with RCDH, especially in cases with no left shift in the mediastinum in the imaging. Preoperative evaluation for surgery in such cases needs to be managed as if it were a major operation that may require hepatectomy or partial pneumonectomy.
ABSTRACT
Objective:To explore the value of fetal lung volume and mediastinal shift angle (MSA) based on fetal MRI in predicting the prognosis of congenital diaphragmatic hernia (CDH).Methods:Fetuses with left CDH that did fetal MRI in Xinhua Hospital Affiliated with Shanghai Jiao Tong University School of Medicine from September 2016 to January 2022 were retrospectively collected. There were 65 patients, and their gestational age was 29 (26, 35) weeks when they were diagnosed with left CDH by MRI. Observed fetal lung volume and MSA were measured based on fetal MRI, and observed/expected lung volume (o/eFLV) based on gestational age was calculated. The clinical data were collected from birth to discharge, and patients were divided into survival group and death group in case of prognosis at discharge, with 54 cases in the survival group and 11 cases in the death group. The student′s t test was used to compare the difference of o/eFLV and MSA between the survival group and the death group, and the receiver operating characteristic (ROC) curve was used to evaluate the value of o/eFLV and MSA in predicting the prognosis of left CDH. Results:The o/eFLV of the survival group was 51.5%±18.3%, higher than that of the death group (27.8%±4.4%), and the difference was significant ( t=8.29, P<0.001). The MSA of the survival group was 33.1°±1.2°, lower than that of the death group (41.8°±2.7°), and the difference was significant ( t=-11.15, P<0.001). The area under the ROC curve (AUC) of o/eFLV to predict the fetal survival or death was 0.939 (95%CI 0.851-0.983), the cutoff value was 33.8%, the sensitivity was 100%, the specificity was 88.9%. The AUC of MSA was 0.998 (95%CI 0.941-1.000), the cutoff value was 37.2°, the sensitivity was 100%, the specificity was 98.2%. Conclusions:The o/eFLV and MSA that were measured based on fetal MRI can effectively predict the fetus′s prognosis with left CDH.
ABSTRACT
Objective:To investigate the treatment of preterm and low birth weight infants with congenital diaphragmatic hernia (CDH) and to share the experience.Methods:This retrospective study enrolled 117 newborns with CDH who underwent major surgery at Children's Hospital, Capital Institute of Pediatrics from May 1, 2011, to March 31, 2022. Based on gestational age and birth weight, the infants were divided into the preterm and/or low birth weight group (gestational age < 37 weeks and/or birth weight less than 2 500 g, n=41) and the control group (gestational age ≥ 37 weeks and birth weight ≥ 2 500 g, n=76). Furthermore, the preterm and/or low birth weight infants were divided into the thoracoscopic surgery subgroup ( n=31) and the open surgery subgroup ( n=10) according to the surgical approach. Statistical analysis of the data was performed using two independent sample t-tests, rank sum tests, Chi-square test, or Fisher's exact probability test. Results:Preoperative data showed that the Apgar scores at 1 min [7.0 (6.0-8.0) vs 9.0 (8.0-9.8), Z=－4.03] and 5 min [9.0 (8.0-10.0) vs 9.0 (9.0-10.0), Z=－2.13] of the preterm and/or low birth weight infants were both lower than those in the control group (both P<0.05), while the proportion of infants with moderate to severe pulmonary hypertension was higher [68.3% (28/41) vs 38.2% (29/76), χ 2=9.68, P<0.05]. There were no statistically significant differences between the two groups in terms of the proportion of thoracoscopic surgery, operation time, right diaphragmatic hernia, presence of hernia sac, grading of the defect, presence of liver herniation, and application of mesh (all P>0.05). Regarding the postoperative outcomes, the death rate in the preterm and/or low birth weiht group was higher compared to the control group [36.6% (15/41) vs 13.2% (10/76), χ 2=8.70, P<0.05]. Additionally, the time required to resume full enteral nutrition after surgery was longer in the preterm and/or low birth weight group than that in the control group [25 d (18-29 d) vs 16 d (10-25 d), Z=2.31, P<0.05]. The thoracoscopic subgroup had a lower mortality compared to the open surgery subgroup [25.8% (8/31) vs 7/10, P<0.05]. The thoracoscopic surgery subgroup had a higher Apgar score at 1 min after birth [(7.4±1.6) vs (6.0±2.2), t=2.20, P<0.05], later age at operation (hours after birth) [31.0 h (23.0-48.0 h) vs 17.0 h (4.7-24.5 h), Z=2.57, P<0.05], a lower proportion of infants operated within 24 hours after birth [32.3% (10/31) vs 8/10, P<0.05], and longer duration of operation [170.0 min (122.0-200.0 min) vs 110.0 min (87.3-120.0 min), Z=3.65, P<0.05]. Conclusions:In this study, a higher mortality in the preterm and/or low birth weight group compared to the control group was observed, which may be attributed to the higher proportion of neonates with moderate-severe pulmonary hypertension. The thoracoscopic diaphragmatic repair can be attempted for preterm and low birth weight infants who have relatively stable respiratory and circulatory functions.
ABSTRACT
Introducción: La observación del diafragma con el ultrasonido ha sido posible desde hace más de cuatro décadas; recientemente se le ha dado importancia a la valoración ultrasonográfica del diafragma en el proceso de destete del paciente ventilado. Objetivo: Describir la utilización de la ecografía diafragmática en la evaluación del proceso de destete en dos pacientes. Presentación de caso: Se presentan dos casos, el primer caso paciente femenino de 79 años con diagnóstico de infarto cerebral, coma y bronconeumonía; que precisó ventilación mecánica invasiva y previa prueba de ventilación espontánea. Se le realizó ultrasonido de diafragma donde se comprobó alta probabilidad de falla en la extubación, por lo que se modificó el esquema de destete para corregir las causas. El segundo paciente masculino de 68 años con diagnóstico de neumonitis aspirativa por queroseno que necesitó soporte ventilatorio invasivo; cuando presentó mejoría del cuadro inicial y parámetros de oxigenación, se le evaluó la función diafragmática mediante ultrasonografía se comprobó alta probabilidad de éxito en la extubación, se logró sin complicaciones. Conclusiones: Se utilizó la ultrasonografía diafragmática, emerge como una herramienta de fácil acceso y bajo costo, en la evaluación del proceso de destete en los pacientes ventilados, permitió la exploración de la función del diafragma en directo y en pie de cama. La valoración de la excursión diafragmática y la fracción de engrosamiento diafragmático proporcionó una escala predictiva valiosa, para prever que pacientes tendrán una extubación exitosa o no(AU)
Introduction: The observation of the diaphragm with ultrasound has been possible for more than four decades; but only recently has importance been given to the ultra-sonographic assessment of the diaphragm in the weaning process of the ventilated patient. Objective: To describe the use of diaphragmatic ultrasound in the evaluation of the weaning process in two patients. Case presentation: Two cases are presented, the first case is a 79-year-old female patient with a diagnosis of cerebral infarction, coma and bronchopneumonia; that she required invasive mechanical ventilation and after a spontaneous ventilation test, an ultrasound of the diaphragm was performed, where a high probability of failure in extubation was verified, for which the weaning scheme was modified to correct the causes. The second 68-year-old male patient diagnosed with kerosene aspiration pneumonitis that required invasive ventilator support; that when he presented improvement of the initial symptoms and oxygenation parameters, his diaphragmatic function was evaluated by ultrasonography, verifying a high probability of success in extubation, achieved without complications. Conclusions: Diaphragmatic ultrasonography emerges as a tool of easy access and low cost, in the evaluation of the weaning process in ventilated patients, allowing the exploration of the function of the diaphragm in direct and at the foot of the bed. The evaluation of the diaphragmatic excursion and the fraction of diaphragmatic thickening provide us with a valuable predictive scale, to anticipate which patients will have a successful extubation or not(AU)

Introducción: Las células de Hürtle fueron descritas por Max Askanazy en 1898, aunque su denominación inapropiada ha permanecido en el léxico. Pueden observarse en una amplia variedad de lesiones tiroideas, desde afecciones no neoplásicas hasta francamente malignas. Caso clínico: Femenina de 62 años de edad, asmática e hipertensa controlada, alérgica al yodo y a la penicilina, quien inicia enfermedad actual 1 año previo al presentar aumento de volumen en región anterior del cuello. Ecografía tiroidea reportó glándula aumentada de tamaño, con nódulo tiroideo derecho, complejo de 4 cm; y nódulo tiroideo izquierdo, complejo de 2 cm, TI-RADS 4C. Tomografía computarizada reportó lesión ocupantne de espacio del lóbulo tiroideo derecho de 6 cm y nódulos tiroideos izquierdos de 3 y 2 cm. Pruebas tiroideas sin alteraciones. Se realizó tiroidectomía total. Diagnóstico histopatológico: adenoma de células de Hürtle. Conclusión: En la actualidad, el término correcto es neoplasia de células oncocíticas, bien sea para el adenoma o para el carcinoma. Este tipo de tumores se presenta con mayor frecuencia en mujeres de mediana edad y con un tamaño considerable al momento del diagnóstico. Es necesario establecer un protocolo de acción ante el diagnóstico presuntivo mediante punción por aspiración por aguja fina, debido a la dificultad para diferenciar entre patología benigna y maligna, con la finalidad de garantizar una conducta terapeútica adecuada(AU)
Introduction: Hürtle cells were described by Max Askanazy in 1898, although their inappropriate name has remained in the lexicon. They can be seen in a wide variety of thyroid lesions, from non-neoplastic to frankly malignant conditions. Clinical case: A 62-year-old female, asthmatic and controlled hypertensive, allergic to iodine and penicillin, who started the current disease 1 year before presenting volume increase in the anterior region of the neck. Thyroid ultrasound reported an enlarged gland, with a 4-cm complex right thyroid nodule; and left thyroid nodule, 2 cm complex, TI-RADS 4C. Computed tomography reported a 6 cm space-occupying lesion of the right thyroid lobe and 3 and 2 cm left thyroid nodules. Thyroid tests without alterations. Total thyroidectomy was performed. Histopatological diagnosis: Hürtle cell adenoma. Conclusion: Currently, the correct term is oncocytic cell neoplasm, either for adenoma or for carcinoma. This type of tumors occurs more frequently in middle-aged women and with a considerable size at the time of diagnosis. It is necessary to establish a protocol of action before the presumptive diagnosis by means of fine needle aspiration procedure, due to the difficulty to differentiate between benign and malignant pathology, with the purpose of guaranteeing an adequate therapeutic conduct(AU)

Introducción: La hernia diafragmática surge como resultado del movimiento de los órganos abdominales hacia el tórax a través de un defecto del diafragma resultante de varios tipos de lesiones, que a menudo representan un desafío diagnóstico y terapéutico. La hernia diafragmática traumática es una enfermedad infrecuente. El trauma diafragmático rara vez es aislado, la mayoría de las veces se acompaña de otras lesiones toracoabdominales, cerebrales o musculoesqueléticas, siendo estas comorbilidades más graves responsables del mal pronóstico y aumento de la mortalidad. Caso clínico: Anciana de 90 años de edad, hipertensa, quien inicia cuadro clínico 48 horas previas a su ingreso, cuando posterior a caída del plano de bipedestación presenta disminución del estado de consciencia, náuseas, vómitos y disnea en reposo. Rx de tórax evidencia asas intestinales en hemitórax derecho. Se realizó laparotomía exploradora. Conclusión: Las hernias diafragmáticas traumáticas son infrecuentes, con incidencia <3%, sintomatología inespecífica y relacionadas generalmente con lesiones asociadas al trauma. Siempre se debe sospechar de una HD ante un paciente con antecedente de trauma cerrado de alto impacto o penetrante, en función de la cinética y mecanismo de lesión. El diagnóstico supone un reto para el cirujano, debiendo apoyarse en una firme sospecha y estudios radiológicos. Su tratamiento es quirúrgico, debiendo ser individualizado, con abordajes torácicos o abdominales en función del caso. La técnica a emplear dependerá de las características del defecto, de la fase del diagnóstico y la experiencia del equipo quirúrgico(AU)
Introduction: Diaphragmatic hernia arises as a result of the movement of the abdominal organs towards the thorax through a defect in the diaphragm resulting from various types of injuries, which often represent a diagnostic and therapeutic challenge. Traumatic diaphragmatic hernia is a rare disease. Diaphragmatic trauma is rarely isolated, most of the time it is accompanied by other thoracoabdominal, brain or musculoskeletal injuries, these more serious comorbidities being responsible for the poor prognosis and increased mortality. Clinical case: A 90-year-old woman with hypertension , who began a clinical picture 48 hours prior to admission, when after falling from the standing plane he presented a decreased state of consciousness, nausea, vomiting, and dyspnea at rest. Chest x-ray shows intestinal loops in the right hemithorax. Exploratory laparotomy was performed. Conclusion: Traumatic diaphragmatic hernias are rare, with an incidence of <3%, non-specific symptoms, and generally related to injuries associated with trauma. HD should always be suspected in a patient with a history of high-impact or penetrating blunt trauma, depending on the kinetics and mechanism of injury. Diagnosis is a challenge for the surgeon, and must be based on a firm suspicion and radiological studies. Its treatment is surgical, and must be individualized, with thoracic or abdominal approaches depending on the case. The technique to be used will depend on the characteristics of the defect, the diagnostic phase and the experience of the surgical team(AU)

La hernia diafragmática congénita es un defecto en el diafragma que lleva a la herniación del contenido abdominal a la cavidad torácica durante el período intrauterino. La morbimortalidad está determinada por la asociación con otras malformaciones, el grado de hipoplasia pulmonar y la presencia de hipertensión pulmonar secundaria. Presenta una incidencia estimada de 1 cada 2.500-3.000 recién nacidos vivos, constituyendo en un 60% una malformación aislada. Es una patología evolutiva que puede ser diagnosticada a partir de la semana 20-24, la ubicación más habitual es la posterolateral izquierda. Se trata de una patología que requiere ingreso a cuidados intensivos al nacimiento y luego de lograda la estabilización del paciente es de sanción quirúrgica. Los objetivos de este trabajo son conocer las características generales de la patología para sistematizar el manejo logrando así un óptimo asesoramiento de los padres a nivel prenatal y seguimiento postnatal del recién nacido.
Congenital diaphragmatic hernia is a defect in the diaphragm that leads to herniation of theabdominal contents of the thoracic cavity during the intrauterine period. Morbidity and mortality are determined by the association with other malformations, the degree ofpulmonary hypoplasia and the presence of secondary pulmonary hypertension.It has an estimated incidence of 1 every 2,500-3,000 live newborns, and in 60% of the cases it is an isolated malformation. It is an evolutionary pathology that can be diagnosed from week 20-24; it is most commonly located in the left posterolateral. It is a pathology that requires intensive care at birth and after delivery and once the patient has been stabilized, surgical action is required. The objectives of this work are to understand the general characteristics of the pathology in order to refine its manipulation and achieve optimal counseling for parents at the newborn's prenatal and postnatal stages.
