RESUMO
Objective@#To evaluate the effectiveness of enteral nutrition in children with accidental upper gastrointestinal injury.@*Methods@#The medical records of 128 patients with mechanical or chemical gastrointestinal mucosal injury, who were hospitalized in Department of Gastroenterology, Children's Hospital of Zhejiang University School of Medicine from January 1, 2011 to December 30, 2017, were collected. All cases were treated with enteral nutrition. The clinical features and etiologies were retrospectively analyzed. Weight-for-age Z score and lab findings including white blood cells, C-reactive protein, neutrophils, albumin, prealbumin, urea nitrogen and hemoglobin before and after treatment were extracted. The clinical characteristics, the duration of enteral nutrition and gastrointestinal mucosal healing between different etiologies were further analyzed. Normal distribution variables and categorized variables were compared with t test and χ2 test respectively, and abnormal distribution data was compared with Wilcoxon test.@*Results@#Among all the cases, 77 were males and 51 were females. The average age was (29±22) months. The mean duration of hospitalization and enteral nutrition were (11±7)d and (27±20)d respectively. Vomiting was the most common clinical presentation (72 cases, 56.3%). In 79 cases the problems were caused by mechanical injury, among which coins were most commonly seen. The rest 49 cases were caused by chemical injury. However, the duration of hospitalization ((13±8) d vs. (10±6)d, t=-3.089, P=0.002) and enteral nutrition ((39±22) vs. (19±14) d, t=-5.365, P=0.000) were longer in children with chemical injury than those with mechanical injury. A total of 112 cases got complete blood count and C-reactive protein both before and after enteral nutrition. Inflammatory markers, including leukocytes ((7.7±2.7) ×109/L vs. (13.7±5.0) ×109/L, t=12.244, P <0.05), neutrophils ((3.4±1.9)×109/L vs. (9.4±4.6) ×109/L, t=13.655, P<0.05), and C-reactive proteins (5.0(3.0,7.8) vs. 13.5(6.0,40.5) mg/L, Z=7.776, P <0.05) were significantly decreased. The nutritional markers, including the weight-for-age z score (-0.1 ± 1.0 vs. 0.0 ± 1.0, t=-2.622, P=0.010) and the prealbumin (0.1 ± 0.1 vs. 0.2 ± 0.0 g/L, t=-3.671, P=0.001) were significantly increased. Fifty-five (82.1%) children in mechanical injury group recovered in 4 weeks, while 27 (79.4%) children in chemical injury group recovered in 7 weeks.@*Conclusion@#Enteral nutrition can provide adequate nutritional requirements for children with upper gastrointestinal injury, and may help to decrease imflammation and improve mucosal healing.
RESUMO
Objective@#To explore the clinical features and complications of foreign bodies in the upper gastrointestinal tract in children and to investigate the effectiveness of endoscopic management.@*Methods@#Data of patients with foreign bodies in upper gastrointestinal tract were collected retrospectively at Endoscopy Center, the Children's Hospital, Zhejiang University School of Medicine, from January 2011 to December 2016. Clinical characteristics, the types of foreign bodies, the location and duration of foreign body impaction were summarized. The risk factors of complications and endoscopic removal failure were analyzed by using Logistic regression analysis.@*Results@#A total of 1 334 patients (825 males and 509 females) were enrolled. The median age was 2.5 years, with a range from 0.25 to 15 years and peak age 1-3 years. Twenty patients had esophageal diseases. The most common foreign body ingested was coin (n=964, 72.3%). Foreign bodies were most commonly located in the esophagus (n=1 002, 75.1%), especially in the upper esophagus (n=857, 85.5%). The duration of foreign body impaction ranged from 3 hours to 5 years. Among 1 334 patients, 252 patients (18.9%) developed complications, including ulcers (n=101, 40.0%) and perforations(n=13, 5.2%). The success rate of endoscopic removal was 96.6% (n=1 288). By Logistic regression analysis, sharp foreign body ingestion (OR=6.893, 95%CI: 4.421-10.746) , esophageal impaction (OR=5.253, 95%CI:3.352-8.233) and foreign body impaction longer than 24 hours (OR=4.336, 95%CI:3.091-6.082) were risk factors of complications. Sharp foreign body ingestion was the risk factor of endoscopic failure (OR=5.372, 95%CI:2.773-10.406) .@*Conclusions@#Coin is the most common foreign body in upper gastrointestinal tract. Sharp foreign bodies impacted in the esophagus over 24 hours increase the risk of complications. Endoscopic removal of foreign bodies from the upper gastrointestinal tract in children has a high success rate. Sharp foreign body ingestion increases the risk of failure in endoscopic removing.
RESUMO
OBJECTIVE: To understand the clinical features of gastrointestinal cow's milk allergy in children, and to assess the importance of cow's milk challenge. METHOD: An analysis was performed on the clinical manifestations and the challenge results of 50 children who received cow's milk challenges after admission to the department of gastroenterology, Children' s Hospital of Zhejiang University School of Medicine from January,2009 to December, 2012. The value of immunoglobulin E antibody was also analyzed among the 50 children, 25 cases were male and the other 25 were female. The youngest subject was 1. 6 months old, and the oldest was 20 months, most of the cases were younger than 6 months (36 cases). RESULT: (1) Diarrhea (27 cases, 54%) and hematochezia (25 cases, 50%) were the most common clinical features, vomiting, hematemesis and abdominal distention were rare. (2) Cow's milk challenges failed in 58% of the cases, 90% of whom showed delayed allergy. Diarrhea (19 cases, 73%) was the major later presentation, whereas the immediate hypersensitivity showed angio-edema, gastrointestinal symptom and rash. (3) The neutrophil count ((3.8 ± 2.8) x 10(9)/L vs. (2.5 ± 1.3) x 10(9)/L) was higher after challenge among children who failed the challenge. The change in the count of blood cell, neutrophil and platelet was studied, however, there were no statistical differences between the challenge-failed children and the passed ones. (4) Forty-seven cases had milk specific immunoglobulin E antibody test, and 5 showed positive results, 4 of whom were seen among the challenge-failed children. CONCLUSION: Diarrhea and hematochezia was the most common clinical manifestation, and cow's milk protein induced proctocolitis was the most common disease in practice. It is important and necessary to perform cow's milk challenge.
