The Results of Pneumatic Balloon Dilatation Treatment in Children with Achalasia: A Single-Center Experience.

BACKGROUND/AIMS: Achalasia is a primary motility disorder characterized by a relaxation disorder of the lower esophageal sphincter. In pneumatic balloon dilatation, which is one of the treatment methods, the muscle fibers are torn with an endoscopically inflated balloon in the lower esophageal sphincter. This study aimed to evaluate the results of long-term pneumatic balloon dilatation treatment in our clinic for children diagnosed with achalasia. MATERIALS AND METHODS: Pediatric patients who underwent pneumatic balloon dilatation with a diagnosis of achalasia in our pediatric gastroenterology clinic between 2016 and 2021 were included in the study. Demographic data of the patients, clinical findings at diagnosis, and follow-up results were evaluated retrospectively. RESULTS: Ten patients who underwent 18 pneumatic balloon dilatation operations were included in the study. The mean follow-up period of the patients was 23.7 ± 14.1 months. It was observed that the procedure was performed once in 3 (30%) patients, twice in 2 (20%) patients, and 3 times in 3 (30%) patients. It is noteworthy that the diameter of the balloon used in the first procedure in patients who needed repeated operations was less than 30 mm. No complications were observed except for chest pain, which was detected in 1 patient. CONCLUSION: When the patients who needed recurrent dilatation were evaluated, it was noted that the diameter of the balloon in which the first procedure was performed in these patients was smaller. This study is an important contribution to the literature due to the scarcity of the pediatric achalasia data, in which long-term results related to pneumatic balloon dilatation are reported in Turkey.

Evaluation of Children Undergoing Endoscopic Procedures During the Normalization of the Coronavirus Disease 2019 Pandemic.

BACKGROUND: Given that procedures involving gastrointestinal tract lumens are high-risk and aerosol forming, the functioning of endos- copy units has been reorganized during the coronavirus disease 2019 pandemic. Guidelines recommend that all personnel should carry out procedures in a negative-pressure room with personal protective equipment; in the absence of a negative-pressure room, an ade- quately ventilated room should be used. During the normalization of the coronavirus disease 2019 pandemic, this study aimed to evalu- ate children who were treated in our endoscopy unit without a negative-pressure chamber in terms of coronavirus disease 2019 after procedures. METHODS: Patients were questioned and evaluated prospectively for symptoms and contact with coronavirus disease 2019 patients on before and 7th and 14th days after the procedure. RESULTS: Seventy-eight procedures were performed on 69 patients over a 3-month period. The mean age of patients was 12.0 ± 5.1 years. Among all the procedures performed, 54 (69.2%) involved upper gastrointestinal system (GIS) endoscopy and 24 (30.8%) involved colo- noscopy. Furthermore, 72 (91.3%) of the procedures were performed in the pediatric endoscopy unit, and 6 (7.7%) were performed in the operating room. No coronavirus disease 2019 symptoms or presence was detected in the patients. CONCLUSION: The ideal setting for an endoscopic procedure is in a negative-pressure chamber. However, this study has shown that endoscopic procedures can be performed in units without negative-pressure rooms but with appropriate protective equipment and evaluation of patients for coronavirus disease 2019 symptoms.

Evaluation of Thyroid Function Tests in Children with Chronic Liver Diseases

Objective: Studies examining changes in thyroid function in the course of chronic liver disease have mostly been conducted in adults. The aim of this study was to investigate thyroid dysfunction in children with chronic liver diseases. Methods: Between 2005 and 2018, patients aged up to 18 years of age, diagnosed with chronic liver disease and had thyroid function test results available were included. Anthropometric characteristics, liver and thyroid function results were collected and analyzed. Results: The study included 107 (53 female; 49.5%) patients aged between one month and 18 years-old. Of the 107 patients, 96 (89.7%) had normal thyroid function results, seven (6.5%) had subclinical hypothyroidism (SH) and four (3.7%) had euthyroid sick syndrome. Of the patients with SH, one (14.2%) had glycogen storage diasease, one (14.2%) had biliary atresia, one (14.2%) had undiagnosed cholestatic liver disease, one (14.2%) had Alagille syndrome, one (14.2%) had idiopatic hepatitis, one (14.2%) had progressive familial intra-hepatic cholestasis and one (14.2%) had congenital hepatic fibrosis. Spearman correlation analysis showed a negative correlation between free tri-iodothyronine and direct bilirubin (r=-0.329, p=0.027). Conclusion: In conclusion, euthyroid sick syndrome or SH may affect up to 10% of children with chronic liver diseases. It is suggested that thyroid function should be evaluated in cases of pediatric chronic liver disease at diagnosis and during follow-up. Moreover, this study is the first to show a negative correlation between free T3 levels and direct bilirubin, suggesting a possible association between liver disease severity and thyroid function.
