Objective:To review and analyze clinical data of patients with invasive pulmonary aspergillosis and mucormycosis, and to explore the surgical indication.Methods:Clinical data of 10 patients with invasive pulmonary aspergillosis and mucormycosis were analyzed retrospectively from March 2018 to November 2022 in our hospital, Department of Thoracic Surgery.Results:The age of children varied from 2.58 years old to 16.00 years old and 6 children were males while 4 females. Five patients suffer from invasive pulmonary aspergillosis. Five patients suffer from invasive pulmonary mucormycosis. The operative indication of 7 patients was the risk of massive bleeding in the airway. The surgical indication for two patients is to control infection and continue treating malignant tumors. One patient chose surgical treatment because the infection could not be cured after long-term antifungal treatment but the focus was limited. Two patients died of sudden acute hemoptysis before operation, the prognosis of 8 patients undergoing surgical treatment was good.Conclusion:The lethal rate of invasive pulmonary aspergillosis and mucormycosis is very high. Antifungal drug treatment combined with timely surgical treatment can save patients lives.

Objective:To compare the clinical effect of surgical treatment of congenital preauricular fistulas in children during the local infection period and static inflammatory period. Methods:Forty children with congenital preauricular fistula infection treated in our hospital from January 2020 to December 2022 were selected as the experimental group, and 39 children with congenital preauricular fistula inflammation at static period were selected as the control group. The fistula of the two groups of children aged between 1-14 years old was located in front of the foot of the ear wheel or the foot of the ear wheel, and all were unilateral fistulas. The postoperative follow-up was 6 months to 2 years, and the efficacy of the two groups was compared. Results:There was no significant difference in the healing rate of stage Ⅰ and stage Ⅱ between the two groups（P>0.05）. There was no significant difference in fistula recurrence rate and satisfaction with the preauricular scar between the two groups after treatment（P>0.05）. There was no significant difference in postoperative hospital stay between the experimental group and the control group（P>0.05）. Conclusion:The effect of surgical treatment of congenital preauricular fistula in the infected period is similar to that of surgical treatment in the static period of inflammation, and it can reduce the pain of dressing change under local anesthesia in children, avoid the second operation in children, and reduce the economic cost. This treatment method is worthy of clinical promotion. Appropriate incision and resection method were designed according to the fistula and infection sites.

Objective:To summarize the clinical features, diagnosis and treatment experience of esophageal hamartoma in children.Methods:From December 2013 to December 2019, 3 cases of esophageal hamartoma were admitted to our hospital, and a retrospective analysis was conducted.Results:There were 1 male and 2 females, with an average age of 6.4 years old. The clinical manifestations were vomiting in 2 cases and dysphagia with esophageal foreign body sensation in 1 case. Esophagography, chest contrast-enhanced CT, and esophagoscopy showed esophageal stenosis or esophageal mass effectg, and esophageal dilatation above the affected segment. The tumor was found in upper esophagus in 1 case and lower esophagus in 2 cases. Tumors were complete resection in all 3 cases and the patients were discharged smoothly. All the 3 cases were followed up after surgery for 10-74 months(average 37 months), and 1 case had gastroesophageal reflux. No stenosis or recurrence was found in all the cases, and all the patients could eat normal diet.Conclusion:The main manifestations of esophageal hamartoma in children are vomiting and choking. Complete surgical resection is the main treatment method, and the prognosis is good.

Objective:Gasless laparoscopic surgery using lifting device was first introduced in 1993 mainly for general surgery and gynecology. Here we report its application in bifid rib treatment and explore the feasibility and safety of the surgery.Methods:From July 2008 to December 2019, according to the enrollment criteria, 278 patients of bifid ribs were treated at the Department of Thoracic Surgery, Beijing Children’s Hospital, Capital Medical University, including 183 males and 95 females, the mean age was(5.7±2.5) years old. There were 242 cases of single bifid rib and 36 cases of multiple bifid ribs. The bifid ribs were more common on the right side, as 184 cases had bifid ribs on right side, while only 68 cases on the left side and 26 cases on both sides. Patients’ clinical data were retrospectively summarized and analyzed, including the patients’ gender, age, location and type of bifid rib, perioperative outcome, and follow-up.Results:All the 278 patients successfully completed the operation. The abnormality was most frequently found in the fifth rib(incidence ranking: fifth > fourth > third > sixth). The mean operation time was(64.5±16.1)min, and the mean blood loss was(4.8±2.1)ml. No serious complications occurred during the surgery. Follow-up was done for 7 to 120 months, and no recurrent patients were observed.Conclusion:Gasless endoscopy with lifting device has been used as a safe and effective method to treat bifid ribs in our hospital. This surgery leads to less injury, smaller incision, and no scars on the front chest. Gasless endoscopic surgery with lifting device can be one of the options for correcting bifid ribs.

Objective:To study serum procalcitonin (PCT), C-reactive protein (CRP) and platelet count (PLT) in evaluation of severity of acute cholangitis (AC).Methods:Ninety patients with AC who were treated at the General Surgery Department, Guangming Hospital, Liaocheng, Shandong Province from January 2016 to December 2018 entered into the observation group, while 60 patients with bile duct stones but without infection treated at the hospital during the study period entered into the control group. Using the " Guidelines for the Diagnosis and Treatment of Acute Biliary Tract Infections" , the study group of patient was further divided into the mild infection, moderate infection, and severe infection groups. The PCT, CRP and PLT levels of all the subjects were checked. Spearman correlation was used to analyze the relationship between PCT, CRP, PLT indexes with severity of infection. The receiver operating characteristic curve was used to analyze the sensitivity and specificity of PCT, CRP and PLT in the diagnosis of patients with different degrees of infection.Results:In the observation group, there were 46 males and 44 females with a Mean±SD age of (45.6±21.1) years. In the control group, there were 30 males and 30 females, with a Mean±SD age of (45.0±19.3) years. The levels of PLT in the observation group and the control group were (8.2±1.1) ng/ml and (0.4±0.1) ng/ml, respectively. The corresponding CRP were (92.7±21.1) mg/L and (6.1±1.0) mg/L, respectively. The observation group had higher levels than the control group. The PLT counts were (62.6±17.6)×10 9/L and (156.3±35.3)×10 9/L for the two groups, with the observation group having lower platelet count than the control group (both P<0.05). The severity of infection was positively correlated with blood PCT levels and CRP indicators ( r=0.427, r=0.584, all P<0.05), and negatively correlated with the PLT ( r=-0.429, P<0.05). The sensitivity and specificity of PCT using a cut-off value of 9.4 μg/L were 84.0% and 65.0%, respectively, which were higher than the CRP using a cut-off value of 145.7 mg/L. The sensitivity and specificity were 67.0% and 48.0%, respectively. When PLT using a cut-off value of 52.8×10 9/L, the sensitivity and specificity were 71.0% and 52.0%, respectively. Conclusions:Changes in serum PCT, CRP and PLT reflected the severity of infection in patients with AC; PCT had a higher sensitivity and specificity, and it can be used to guide treatment.

Objective To evaluate the thoracic status of patients with funnel chest by quantitative evaluation of chest Xray,and to explore the effect of Nuss surgery.Methods From October 2006 to February 2011,according to the inclusion criteria,there were 47 cases enrolled our group at last,then divided the cases into 3 groups,including pre-operative of Nuss procedure,recent post-bar removal and further post-bar removal.We measured data on chest radiography and statistical analysis,including the maximal distance of the outer boundary of each rib pairs (C,from the 1 st pair to the 9th),the distance between lung apex to the costophrenic angle (H) and the distance between the two costophrenic angles(W).Results All the 47 cases completed the Nuss procedure and Nuss bar removal safely and effectively.All the patients were followed up from 30 to 36 months,without recurrence or long-term complications.Three groups of thoracic data showed an increasing trend,recent post-bar removal and further post-bar removal compared with the same age normal children,the thoracic data of the Nuss bar position were shortened.With the prolongation of time after Nuss bar removal,thoracic data gradually approaching normal.Conclusion We can evaluate the level of pectus excavatum and effect of Nuss procedure through measuring the chest wall data.The chest wall of post-bar removal was significantly improvement compared to the cases of pre-Nuss procedure.There is some restrictions on the thoracic by the Nuss bar.we learn that the limitation of thoracic can be improve after some time.

Objective: To evaluate the efficacy of using sternal suspension technique in correcting pectus excavatum after open repair of congenital heart disease and improve the safety of this technique. Methods: A retrospective study was conducted for 8 cases of pectus excavatum treated with sternal suspension procedure after open repair of congenital heart disease from October 2005 to October 2018 in our institution, 5 males and 3 females. The median age of patients was 5.75 years (range 3.75-12.33 years) and the median Haller index was 4.20(range 3.60-5.19). All patients underwent cardiac ultrasound and chest CT scan to evaluate the severity retrosternal adhesions. Results: All patients underwent the sternal suspension procedure successfully with a median operation time 55 min (range 30-230 min) and a median blood loss of 2 ml (range 2-120 ml). There was one patient suffered pneumothorax after operation. The patients were followed up for 4 months to 13 years with an excellent and good outcome. Conclusion Sternal suspension technique is a safe and effective procedure for pectus excavatum. To improve the security and reduce the incidence of cardiac injury, sternal suspension technique is a promising alternative for pectus patients with severe adhesion after open repair of congenital heart disease.

Objective To explore the establishment of 3D thoracic model by finite element methods,and study the mechanical mechanism of minimally invasive surgery for correcting the chest wall deformity,and provide personalized surgery solution in the future.Methods According to admission and exclusion criteria,we selected 10 cases of pectus carinatum that received chest CT scan.The finite element model of pectus carinatum was established and analyzed by Mimics,ABAQUS,etc.The validity of finite element method for chest wall was verified by comparing the sternal displacement between the simulated values and actual values with the same force.Results The 3D finite element model of pectus carinatum was successfully established and analyzed.The stress distribution of the 10 cases in the posterior ribs was mainly in the 1-6 ribs on both sides,mostly concentrated in the 4th to 6th ribs,and the stress was symmetrical on both sides.Statistical analysis showed that the displacement value of the sternum was correlated,and the validity of the model was verified.Conclusion Mimics,ABAQUS and other finite element modeling and analysis software can effectively establish the thoracic 3D finite element model and mechanical analysis,which can help the further development of personalized minimally invasive surgery for correcting chest wall deformities.
