Objective To analyze the pathological types and causes of misdiagnosis of thyroglossal duct cyst(TGDC).Methods The clinical data of 173 patients diagnosed with TGDC before operation in Tangdu Hospital of Air Force Medical University from January 2013 to January 2023 were retrospectively analyzed.Combined with postoperative pathology,a total of 15 patients were found to be misdiagnosed before operation,and the causes of misdiagnosis were summarized.Results The pathological types of 14 misdiagnosed cases in-cluded seven cases of dermoid cyst,three cases of thyroglossal duct papillary carcinoma,one case of accessory thyroid gland,one case of nodular goiter with intracapsular hemorrhage,one case of cervical lymphadenitis and one case of inflammatory nodule.All the 14 patients underwent standard Sistrunk surgery,and regular follow-up after surgery showed no hypothyroidism,recurrence or metastasis.Preoperative static thyroid imaging proved that the neck mass was vago thyroid in one patient,and surgery was not performed to avoid hypothy-roidism or parathyroidism caused by surgery.Conclusion Misdiagnosis of TGDC as other diseases is rare,cli-nicians should raise awareness to avoid the adverse consequences caused by blind operation.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

Objective:To evaluate the efficacy and safety of sodium hyaluronate gel in preventing adhesion after prophylactic enterostomy.Methods:One hundred and twenty four patients from 6 hospitals were enrolled in this prospective multi-center randomized controlled trial. Patients were randomized into the study group ( n=59) or the control group ( n=65).All patients underwent prophylactic enterostomy. Patients of study group received odium hyaluronate gel for adhesion-prevention,while those in control group did not receive any adhesion-prevention treatment. The incidence of moderate to severe adhesion around the incision in the stoma area were evalutated during stoma reduction surgery. Results:The incidence of moderate to severe adhesion around the incision in the stoma area was 6.3% in the study group, the difference was statistically significant ( P<0.05) compared to that of the control group (32.6%). Conclusion:Sodium hyaluronate gel can safely and effectively reduce the incidence of moderate and severe adhesions after abdominal surgery.

At present, the surgical treatment of upper gastric cancer, including esophago-gastric junction cancer, mainly includes the total gastrectomy and proximal gastrectomy. After total gastrectomy, the reconstruction of digestive tract is completed through the anastomosis of esophagus and jejunum. Patients undergoing total gastrectomy often face the risk of poor eating effect and malnutrition. Compared with total gastrectomy, the proximal gastrectomy can preserve part of the gastric tissue, but due to the loss of the normal physiological structure of the cardia, patients have a higher risk of postoperative reflux. In order to solve the problem of reflux, there are many improved operation methods of digestive tract reconstruction after proximal gastrectomy. At present, the choice of total gastrectomy or proximal gastrectomy and the operation methods of digestive tract reconstruction is still controversial. Because of the lack of sufficient theoretical research support. The authors comb the research progress and consider the concept and method of digestive tract reconstruction after total gastrectomy and proximal gastrectomy, in order to provide theoretical basis for clinical work.

Objective: The aim of this study is to o explore the diagnosis, treatment and prognosis of idiopathic subglottic stenosis （ISS） Method: The clinical data of 15 patients with idiopathic subglottic stenosis treated in our department were analyzed retrospectively. The degree of stenosis was classified by the Cotton Airway grading system of Myer, with 8 cases of gradeⅡ, 4 cases of grade Ⅲ and 3 cases of grade Ⅳ. Result: The time of follow-up of HTSS was 0.5-10 years. All 15 patients were successfully extubated without asphyxia, decannulation and wound nonunion. Conclusion For patients with idiopathic subglottic stenosis in the non-progressive stage, active surgical treatment strategy should be adopted and treated individually. The prognosis is satisfactory.

Objective: To assess the outcomes of partial cricotracheal resection (CTR) and extended cricotracheal resection (ECTR) for severe laryngotracheal stenosis. Methods: From November 2009 to September 2017, 18 patients underwent CTR and ECTR at the Department of Otorhinolaryngology Head and Neck Surgery, Tangdu Hospital, Air Force Medical University for severe laryngotracheal stenosis were reviewed retrospectively. There were 12-male and 6-female patients, with the age ranged from 4 to 56 years (median 25 years). The causes were postintubation in 11 cases, cervical trauma in 4, idiopathic in 3. The stenosis located in subglottic and tracheal (n=12), glottic and subglottic and tracheal (n=3), subglottic (n=2), and glottic and subglottic (n=1). Two patients had concurrent unilateral vocal cord palsy.One patient had undergone previous endoscopic balloon dilation and 8 patients had previous laryngotracheal reconstruction. The stenosis was graded according to modified Myer-Cotton classification as follows: Ⅲb (n=1), Ⅲc(n=1), Ⅳa (n=2), Ⅳb (n=12), Ⅳc (n=2). The surgical outcomes and complications were recorded. Results: Among 18 patients,11 of the 12 patients undergoing CTR were decannulated. Five of the 6 patients undergoing ECTR were decannulated. Resected airway length ranged from 1.5 to 4.0 cm (median 2.8 cm). Surgical complications included infection of incision wound in 2 cases, anastomotic granulation in 2, cervical subcutaneous emphysema in 1, aspiration in 1, and unilateral arytenoid prolapse in 1. No recurrent laryngeal nerve injury or tracheoesophageal fistula occurred. The median follow up was 11 months. Conclusions CTR is efficient for severe subglottic and upper tracheal stenosis while ECTR is efficient for subglottic stenosis extended to the glottis. Both procedures also provide a salvage therapy for patients with previous failed treatments.

Objective: To explore the application value of thyroid alar cartilage(TAC) in the laryngotracheal reconstruction of subglotticstenosis in the paediatric population. Methods: Twelve patients(7 males,5 females; range from 2.3 to 12.0 years) with subglotticstenosis who had undergone laryngotracheal reconstruction procedures at our hospital fromSeptember 2016 to July 2018 were analyzed retrospectively.The degree of stenosis was classified according to Myer-Cotton classification system:grade Ⅱ(n=4),grade Ⅲ(n=6) and grade Ⅳ(n=2). The stenosis planes were subglotticbut did not exceed the 3rd tracheal cartilage ring. Results: Of all 12 patients, 11 were decannulated and 1 failed. All patients with grade Ⅱ and Ⅲ patients were decannulated at one procedure. There were no severe complications such as tube dislogement,asphyxia and unhealed wound. Conclusions The TAC for widening laryngotracheal lumen is relatively simple and reliable for laryngotracheal reconstruction in the pediatric population with subglottic stenosis. This would′t cause any structural damage to the laryngeal cavity.
