ABSTRACT
Objective:To explore the clinical application of magnetic foreign body extractor in metal foreign body of upper digestive tract children.Methods:The clinical data of 115 children with metallic foreign bodies in the upper digestive tract who were admitted to the Department of Pediatrics, the Second Affiliated Hospital of Air Force Medical University, from January 2017 to September 2022, were selected as subjects.All the metallic foreign bodies were removed by a self-made metallic foreign body extractor in the department.The clinical characteristics of the metallic foreign bodies in the upper digestive tract were comprehensively analyzed by using descriptive analysis methods, summarize the age, gender, metallic foreign body type, number of the metallic foreign bodies, incarcerated location, retention time, clinical symptoms and complications.Results:A total of 115 children with metallic foreign bodies in the upper digestive tract were included in the analysis, involving 51 males and 64 females, with a mean age of (3.63±2.28) years.The majority was children aged 0-3 years (68/115, 59.1%). Coins (86 cases, 74.8%) were the major foreign bodies in metal foreign body of upper digestive tract, followed by button batteries (11 cases, 9.6%), magnetic balls (8 cases, 7.0%), and others (10 cases, 8.6%). The main clinical symptoms were nausea, vomiting, abdominal pain, chest pain, and foreign body sensation, and button battery ingestion and magnetic balls were easy to produce complications.The primary retention sites of metallic foreign bodies were the gastric fundus (75 cases, 65.2%), followed by upper esophageal segment (38 cases, 33.0%) and lower esophageal segment(2 cases, 1.7%).Conclusions:In children′s metal foreign body of upper digestive tract, coins are the most common foreign bodies that are easily retained in the stomach fundus.Button batteries are prone to cause severe complications and should be removed timely.The self-made metallic foreign body extractor in our department can remove coins, batteries, magnetic balls, nails, chains, party emblems and other metallic foreign bodies.It can shorten the operation time, improve the removal efficiency, and featured by active search, strong adsorption, no mucosal damage and removal with the endoscope, which can be widely used in the clinical treatment of metallic foreign bodies.
ABSTRACT
To investigate the efficacy and safety of modified endoscopic retrograde appendicitis therapy (ERAT) in children with acute uncomplicated appendicitis complicated with intussusception. Data of 6 patients with acute uncomplicated appendicitis complicated with intussusception who received modified ERAT were collected from October 2018 to February 2020 in Pediatrics Department of Tangdu Hospital. The reduction rate of intussusception, the success rate of ERAT appendiceal intubation and endoscopic treatment, the remission time of clinical symptoms, the time of white blood cells return to normal, the length of hospital stay, complications and recurrence were summarized. All the 6 patients were confirmed to be acute uncomplicated appendicitis combined with ileocecal intussusceptions under colonoscopy. Endoscopic intussusception reduction and ERAT were performed successfully. The mean time of disappearance of abdominal tenderness was 1.3 days after the therapy, and the time of white blood cells return to normal was 1 day after surgery. The endoscopic treatment were all successful and the length of hospital stay was 3-6 days. No complications or recurrence of intussusception and appendicitis occurred during the follow-up period of 6-12 months. Modified ERAT can effectively, safely and minimally invitingly treat acute uncomplicated appendicitis with intussusception in children on the basis of definite diagnosis.
ABSTRACT
Objective:To study the value of ultrasound-guided endoscopic retrograde appendicitis therapy in children with uncomplicated appendicitis.Methods:This study was a single center, retrospective study, including all electronic cases of appendicitis diagnosed clinically in Department of Pediatrics, the Second Affiliated Hospital of Air Force Military Medical University from October 2018 to October 2020 and received ultrasound-guided endoscopic retrograde appendicitis therapy.The clinical features, treatment and prognosis of the children were retrospectively analyzed.Results:A total of 152 electronic cases were included, there were 77 males and 75 females, aged(6.84±3.09) years.All the 152 children were treated with ultrasound-guided endoscopic retrograde appendicitis therapy.Intubation success rate and clinical success rate was 98.03%(149/152 cases)and 97.99%(146/149 cases), respectively.The median time of endoscopic therapy was 42.50 (31.00, 56.00) minutes.Mean postoperative hospital stay was (2.81 ±1.41) days, and the mean total hospital stay was (4.19 ±1.71) days.A total of 139 patients were followed up with a median follow-up time of 5 (1, 26) months.During the follow-up, the recurrence rate was 7.19%(10/139 cases), and the median time of recurrence was 2 (1, 3) months.Conclusions:Ultrasound-guided endoscopic retrograde appendicitis therapy had high effective rate and low recurrence rate in children with uncomplicated appendicitis, preserved the physiological function of appendix and avoided radiation damage.It can be used as a safe and effective treatment for acute and chronic uncomplicated appendicitis in children.
ABSTRACT
Objective To investigate the relationship between cow's milk protein allergy(CMPA)and gastroesophageal reflux disease(GERD)and the prognosis of GERD combined with CMPA.Methods Fifty patients(24 boys and 26 girls)with GERD were enrolled in this study from January 2015 to June 2016 at Department of Pediatrics,Tangdu Hospital of the Fourth Military Medical University.All children were treated with serum milk protein soluble IgE(sIgE)and milk protein avoidance test,and those with positive results of children's milk protein by provocation test and those with milk serum protein sIgE negative by milk protein provocation tests were diagnosed as CMPA children with GERD according to the CMPA diagnostic criteria and received diet therapy for 1 month and then their blood eosinophil ratio and 24-hour esophageal pH were monitored.Results Twenty-three cases(46％)of 50 children with GERD were diagnosed as CMPA.There was significant difference in clinical symptoms between GERD group and GERD combined with CMPA group(x2=22.78,P0.05).For children with GERD combined with CMPA,the patients received dietary treatment for 1 month.There was significant improvement in vomiting,runny nose/wheezing/cough and diarrhea(P0.05).The proportions of blood eosinophils were decreased after treatment compared with those before treatment [(2.7±1.8)％vs.(8.2±2.7)％,t=10.006,P<0.01].The results of 5 children's 24-hour esophageal pH monitoring showed that the reflux index and the number of acid GERD episodes were lower than before,and the difference was all statistically significant before and after(all P<0.05).Conclusions The occurrence of GERD in infants is partly related to CMPA,and the treatment of CMPA can relieve the clinical symptoms of GERD.
