RESUMO
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.
RESUMO
Objective:To explore the clinical characteristic, pathogenesis, diagnosis and treatment strategies of gastroinstinal injury caused by magnets ingestion in children.Methods:A retrospective analysis of 46 patients with gastrointestinal tract magnets ingestion in Anhui Provincial Children′s Hospital from October 2017 to September 2021 was performed. Patients were divided into different groups according to gastroinstinal perforation. Some basic information was collected, including gender, age, duration of swallow foreign bodies, quantity of foreign bodies, symptoms, white blood cell, neutrophil, C-reactive protein, therapeutic method, gastroinstinal injury and follow up. Logistic regression. Univariate analysis and multivariate Logistic regression were used to analysis the risk factors of gastroinstinal perforation. Continuous parametric data were summarized using median and interquartile range, differences were evaluated using Wilcoxon Mann-Whitney test.Noncontinuous data were analyzed using chi-square test or corrected chi-square test.Results:Among the 46 patients, there were 33 males and 13 females. The median age was 3 years, with a range of 8 months to 11years. 34 cases had a history of ingesting magnets. The common number of ingested magnets was 2-10 (25 cases). Vomiting (18 cases) and abdominal pain (13 cases)were the commonest complaint. 6 cases tend to pass through the gastrointestinal tract uneventfully, and the remaining cases were successfully extracted by endoscopy (5 cases) and surgery(35 cases). Gastroinstinal perforation was found in 28 cases, and the majority of perforation was located in the ileum (18 cases). Univariate analysis showed that symptom, white blood cell, neutrophil, and CRP were associated with gastroinstinal perforation ( P<0.05). Multivariate Logistic regression analysis showed that symptom( OR=4.715, 95% CI: 1.074-20.696, P=0.040) and CRP( OR=11.605, 95% CI: 1.132-118.981, P=0.039) were independent factors for gastroinstinal perforation. There was no significant correlation between the number of magnets and gastroinstinal perforation ( r=0.276, P>0.05). Conclusions:The ingestion of magnetic foreign bodies in children often requires urgent management.When magnets are located within the prepyloric part of the GI tract, retrieval by endoscopy is recommended.The surgical intervention is required as soon as possible due to the failure of endoscopic treatment.
RESUMO
·AIM:To investigate the surgical method and efficacy of extraction of deep orbital magnetic foreign bodies by mean of an orbital strong magnet.·METHODS: A retrospective analysis of clinical data of patients with deep orbital magnetic foreign bodies ( OMFB ) in Hebei Eye Hospital from June 2014 to May 2017 was processed. A total of 23 eyes were enrolled, among them, 14 eyes of extraorbital OMFB, 9 eyes of intraorbital OMFB. The rate of extraction of foreign bodies and the postoperative complications were observed.·RESULTS: All eyes of intraorbital foreign bodies were successfully extracted with 100% success rate. Twelve of 14 eyes of extraorbital foreign bodies were extracted with 86% success rate. Mild orbital hemorrhage were found in 2 eyes. There was no other obvious complication such as visual loss, orbital massive hemorrhage or limited ocular movement.·CONCLUSION: It's an ideal surgical method to extract the deep orbital magnetic foreign bodies by mean of an orbital strong magnet, with mini-injury, high success rate, short duration and few complications.
