RESUMEN
Objective:To investigate the diagnostic and therapeutic value of one-time biliopancreatic-duct-imaging-system (eyeMax)-assisted endoscopic retrograde appendicitis therapy (ERAT) for children.Methods:A total of 11 children who were diagnosed as having uncomplicated acute appendicitis by imaging in Xi′an Children′s Hospital from August to November 2022 were enrolled. All patients received subscope-assisted ERAT. Subscope was intubated into the appendix cavity to observe the mucosa directly. Appendicitis was treated through cleansing, fecalith extraction, stent drainage. The clinical manifestations under subscope were recorded, as well as the treatment success rate, intubation success rate, the effective rate, complication incidence during and after the operation.Results:The age of 11 children was 7.93±2.67 years old. Appendix intubation was successful in all patients. Congestion and swelling of the mucosa in appendiceal orifice and appendix cavity were seen under the subscope in 11 children. There were 6 cases with appendiceal fecaliths, 8 cases with pus and 6 cases with luminal distortion or stenosis. Perforation was observed in 1 case during the operation and no other complication occurred. All patients were treated under subscope, including flushing appendiceal cavity (11 cases), fecalith extraction with extraction basket (3 cases), and appendiceal drainage with stenting (2 cases). The symptoms and signs were relieved after the operation, and the effective rate within 48 hours was 10/11. There were no procedure-related complications or recurrence during postoperative follow-up for 1 week to 4 months.Conclusion:Acute appendicitis could be diagnosed by observing the appendix cavity directly under one-time biliopancreatic-duct-imaging-system-assisted ERAT, and also could be treated with the system, where appendix could be preserved and radiation damage could be avoided with safety and effectiveness.
RESUMEN
Objective:To evaluate the safety and effectiveness of capsule endoscopy for the diagnosis of intestinal diseases in children.Methods:Clinical data of 113 pediatric patients who received capsule endoscopy in Xi'an Children's Hospital from October 2018 to September 2020 were retrospectively analyzed. The completion rate, passage time of stomach and small intestine, lesion detection rate, adverse reactions and complications of capsule endoscopy were analyzed.Results:Among 113 pediatric patients, 78 (69.03%) were male and 35 (30.97%) were female. The age was (99.8±44.7) months (9-195 months), and 31 (27.43%) were under 7 years old. The minimum weight was 9 kg and the minimum height was 70 cm. Eighty-seven pediatric patients (76.99%) swallowed capsules orally (the oral group) with the minimum age of 4 years and 3 months. Capsules were implanted in 26 pediatric patients (23.01%) under gastroscopy (the gastroscopic group), with the maximum age of 9 years and 2 months. Unexplained abdominal pain (47.79%) and unexplained gastrointestinal bleeding (31.89%) were common in the pediatric patients. The completion rate of capsule endoscopy was 97.35% (110/113), and the detection rate of lesions in small intestine was 31.81% (35/110). The passage time of small intestine in the gastroscopic group was significantly longer than that of the oral group (461.04±129.27 min VS 288.23±107.84 min, t=5.646, P<0.01). There was no significant difference in the passage time of stomach or small intestine among different genders, different ages or different endoscopic examination results ( P>0.05). The positive results of capsule were not correlated with the method of ingestion ( P=0.401, OR=2.562, 95% CI:0.284-23.077), gender ( P=0.154, OR=2.352, 95% CI:0.726-7.616), age ( P=0.949, OR=1.007, 95% CI:0.816-1.242), examination reason ( P=0.246) or small intestine passage time ( P=0.219, OR=1.003, 95% CI:0.998-1.008). No complications such as capsule retention occurred in any pediatric patient. Conclusion:Capsule endoscopy in children is noninvasive, rapid and simple, which can improve the diagnostic rate of small intestinal diseases in children, and can be further promoted in pediatric patients.
RESUMEN
Objective:To evaluate high resolution esophageal manometry (HREM) in peroral endoscopic myotomy (POEM) for pediatric achalasia of cardia (AC).Methods:Data of 30 AC children who received POEM in Xi′an Children′s Hospital from January 2013 to September 2019 were reviewed. HREM was performed before and 6 months after POEM. Preoperative and postoperative lower esophageal sphincter pressure (LESP), 4-second integrated relaxation pressure (4sIRP), Eckardt scores and nutritional status were compared.Results:Children with AC aged between 4-14 years. Postoperative LESP was 5.50±1.13 mmHg (1 mmHg=0.133 kPa), which was significantly lower than that before operation (26.23±4.47 mmHg) with significant difference ( t=-24.623, P<0.001). Postoperative median 4sIRP was 5 mmHg, which was 20 mmHg lower than that before operation (25 mmHg) with significant difference ( Z=-4.786, P<0.001). Postoperative median Eckardt symptom score decreased significantly compared with that before (1 VS 8, Z=-4.796, P<0.001). Severe malnutrition of the AC children improved evidently to normal( Z=-5.166, P<0.001). Conclusion:POEM can significantly improve the characteristics of esophageal dynamics in children with AC, and HREM can be an important indicator for follow-up evaluation of POEM.
RESUMEN
Objective To investigate the influencing factors related to the complications of esophageal foreign body in children. Methods Data of 150 children with esophageal foreign bodies admitted to Xi'an Children' s Hospital from January 2012 to June 2015 were included in the retrospective analysis. Related clinical variables ( gender, age, location, time, size, sharpness, quality, and severity of complications) were statistically analyzed. Results Spearman correlation analysis showed that the age of children was negatively correlated with esophageal foreign body complications (r=-0. 187, P=0. 022), incarceration time ( r=0. 456, P<0. 001) , sharpness ( r=0. 384, P<0. 001) and quality ( r=0. 234, P=0. 004) was positively correlated with the incidence of complications. Non?conditional Logistic regression analysis for polytomous ordinal response showed that incarceration longer than 8 h yielded complication risks 9. 507 times as much as that less than 8 h ( 95%CI:2. 982?30. 309) . Obtuse or sharp foreign body yielded risk 142. 751 times as smooth foreign body did (95%CI:13. 736?1483. 562). Conclusion Incidence and severity of complications of esophageal foreign body in children are closely related to the age of the children, incarceration time and the degree of sharpness. For patients of less than 1 year old, incarceration for more than 8 hours, with an obtuse or sharp foreign body, early diagnosis and treatment is essential.
