ABSTRACT BACKGROUND: Esophageal stenosis (ES) in children is a fixed intrinsic narrowing of the esophagus due to numerous aetiologies. OBJECTIVE: This study aimed to determine the clinical and nutritional impacts of endoscopic balloon dilation (EBD) in Iranian children with an esophageal stricture. METHODS: This retrospective study, pediatric patients (aged <18 years) who underwent EBD for esophageal stricture from April 2015 until March 2020 in Abuzar Children's Hospital (Ahvaz, Iran) were enrolled in the study. Outcome parameters were the frequency of dilations, nutritional status, complications, and clinical success rates. EBD was used in children with radiologic evidence of esophageal stenosis. The nutritional status was evaluated by weight-for-age (z-score). Clinical success was considered as no necessity of EBD for a minimum of one year and/or increasing interval among dilation and the frequency of EBD was less than four times per year. RESULTS: A total of 53 cases (mean age, 4.72±3.38 years) were enrolled. There were 25 (47.2%) females and 28 (52.8%) males. During follow-up, a total of 331 EBD sessions were performed, with an average of 6.24 sessions per patient. There was one case of perforation and one case of mediastinitis, while there was no other complication or mortality. The clinical success rate of EBD therapy was 62.3% (33/53). The mean standard deviation z-score weight-for-age of patients before and after endoscopic dilation was 2.78 (2.41) and 1.18 (1.87), respectively. The t-test showed a significant difference between the weights-for-age (z-score) before and after endoscopic dilation. The majority of the patients had raised weight-for-age (z-score) after EBD treatment. CONCLUSION: EBD attained a good clinical success rate and nutritional improvement in children with an esophageal stricture.
RESUMO CONTEXTO: Estenose esofágica (EE) em crianças é um estreitamento intrínseco fixo do esôfago devido a inúmeras etiologias. OBJETIVO: Este estudo teve como objetivo determinar os impactos clínicos e nutricionais da dilatação do balão endoscópico (DBE) em crianças iranianas com restrição esofágica. MÉTODOS: Foram inscritos neste estudo retrospectivo, pacientes pediátricos (com idade <18 anos) submetidos a DBE para restrição esofágica de abril de 2015 a março de 2020 no Hospital Infantil de Abuzar (Ahvaz, Irã). Os parâmetros de desfecho foram a frequência de dilatações, o estado nutricional, complicações e taxas de sucesso clínico. A DBE foi usada em crianças com evidência radiológica de estenose esofágica. O estado nutricional foi avaliado pelo peso-por-idade (escore z). O sucesso clínico foi considerado como não necessidade de DBE por um período mínimo de um ano e/ou aumento de intervalo entre dilatações e frequência inferior a quatro vezes por ano. RESULTADOS: Foram incluídos 53 casos (média de idade, 4,72±3,38 anos). Eram 25 mulheres (47,2%) e 28 homens (52,8%). Durante o acompanhamento, foram realizadas 331 sessões de DBE, com média de 6,24 sessões por paciente. Houve um caso de perfuração e um caso de mediastinite, enquanto não houve outra complicação ou mortalidade. A taxa de sucesso clínico da terapia de DBE foi de 62,3% (33/53). A média (escore z) peso-para-idade dos pacientes antes e depois da dilatação endoscópica foi de 2,78 (2,41) e 1,18 (1,87), respectivamente. O teste t mostrou uma diferença significativa entre os pesos por idade (escore z) antes e depois da dilatação endoscópica. A maioria dos pacientes havia aumentado o peso por idade (escore z) após o tratamento com DBE. CONCLUSÃO: A DBE atingiu boa taxa de sucesso clínico e melhora nutricional em crianças com restrição esofágica.

Objective To explore the feasibility and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis caused by operation of congenital esophageal atresia. Methods A retrospective analysis was performed on data of 218 children with type Ⅲ esophageal atresia, who underwent surgery in Zhengzhou Children' s Hospital from January 2009 to December 2017. The occurrence of postoperative complications and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis was analyzed. Results Among the 218 patients with congenital esophageal atresia, 92 were type Ⅲa and 126 were type Ⅲb. Postoperative anastomotic leakage occurred in 46 cases (21. 1％), including 29 (31. 5％) of type Ⅲa and 17 (13. 5％) of type Ⅲb. Postoperative anastomotic stenosis occurred in 53 cases (24. 3％), including 29 ( 31. 5％) of type Ⅲa and 24 ( 19. 0％) of typeⅢb. The incidence of anastomotic leakage and anastomotic stenosis in different types was significantly different (χ2=10. 383, P=0. 001; χ2=4. 497, P=0. 034). The 53 cases of anastomotic stenosis underwent 123 times of endoscopic balloon dilation, with mean time of 3. 5±1. 6, and were finally clinically recovery. No esophagus perforation occurred. Among them, 29 cases of type Ⅲa underwent 73 times with mean of 4. 0±1. 8, and 24 cases of type Ⅲb underwent 50 times with mean of 2. 5±0. 7. The difference between the two types was statistically significant (t=-4. 053, P=0. 027). Conclusion Children with type Ⅲa esophageal atresia has a higher incidence of anastomotic stenosis and leakage, and more times of esophageal dilation. Endoscopic balloon dilation is safe and effective in treatment of esophageal stenosis after surgery for patients with congenital esophageal atresia.

The therapeutic target in Crohn's disease (CD) has been raised to the achievement of mucosal healing. Although effective treatments that target cytokines and other molecules has been widely used for CD, intestinal strictures are still a major cause of surgery. Endoscopic balloon dilation (EBD) is known to be an effective and safe intervention for intestinal strictures in CD. Since frequent intestinal resection often results in short bowel syndrome and can decrease the quality of life, EBD can help avoid surgery. EBD with a conventional colonoscope for Crohn's strictures of the colon and ileo-colonic anastomosis has established efficacy and safety. In addition, EBD using balloon-assisted enteroscopy has recently been applied for small bowel Crohn's strictures. Although the evidence is not strong, EBD may become an alternative to surgery in small bowel strictures in CD. EBD and other new methods such as self-expanding stent implantation for Crohn's strictures may be useful and safe; however, it is important to address several issues regarding these interventions and to establish a protocol for combined therapies.

Objective To compare endoscopic sphincterotomy (EST) and endoscopic papillary balloon dilation (EPBD) in treating extrahepatic bile duct stones in terms of similarities and differences. Methods The clinical data of 277 patients with extrahepatic bile duct stones, who were treated from August 2009 to July 2011 in gastroenterology department of Shanghai Changhai Hospital, were retrospectively analyzed, with 168 patients receiving EST and 109 receiving EPBD. The general condition, stone diameter, stone extraction method, operation time, stone-free rate by single procedure, postoperative hospital stay and short-term complications were compared between EST group and EPBD group. Results There were no significant differences in the age, sex ratio, or combination with duodenal diverticulum between the two groups.The mean diameters of the stones were not significantly different between the two groups ([11.3±6.2] mm in EST group vs [10.1±5.7] mm in EPBD group, P=0.105 6). There was no significant difference in the proportions of different stone extraction methods between EST group and EPBD group. The operation time, stone-free rate by single procedure, postoperative hospital stay, and total incidence of short-term complications in EST group were (21.2±3.1)min, 95.2%, (4.1±1.9) d, and 10.1%, and those in EPBD group were (20.7±2.5) min, 94.5%, (4.1±2.0) d, and 12.8%, respectively; with no significant differences found between the two groups (all P>0.05). The incidence of hemorrhage in EST group was significantly higher than that in the EPBD group (3.6% vs 0%, P<0.05). The incidence of hyperamylasemia in EPBD group was significantly higher than that in the EST group (8.3% vs 2.4%, P<0.05). Conclusion EST and EPBD each have their own advantages and disadvantages in the treatment of extrahepatic bile duct stones. Operation mode should be chosen according to the specific condition of patients, but not the size of the stones.

Crohn disease (CD) is a chronic inflammatory bowel disease that affects the entire gastrointestinal tract but is most frequently localized to the large and small bowel. Small bowel endoscopy helps with the differential diagnosis of CD in suspected CD patients. Early diagnosis of CD is preferable for suspected CD conditions to improve chronic inflammatory infiltrates, fibrosis. Small bowel endoscopy can help with the early detection of active disease, thus leading to early therapy before the onset of clinical symptoms of established CD. Some patients with CD have mucosal inflammatory changes not in the terminal ileum but in the proximal small bowel. Conventional ileocolonoscopy cannot detect ileal involvement proximal to the terminal ileum. Small bowel endoscopy, however, can be useful for evaluating these small bowel involvements in patients with CD. Small bowel endoscopy by endoscopic balloon dilation (EBD) enables the treatment of small bowel strictures in patients with CD. However, many practical issues still need to be addressed, such as endoscopic findings for early detection of CD, application compared with other imaging modalities, determination of the appropriate interval for endoscopic surveillance of small bowel lesions in patients with CD, and long-term prognosis after EBD.

BACKGROUND/AIMS: Endoscopic sphincterotomy may be limited in Billroth II gastrectomy because of difficulty in orientating the duodenoscope and sphincterotome as a result of altered anatomy. This study was planned to investigate the efficacy and safety of endoscopic transpapillary large balloon dilation (EPBD) without preceding sphincterotomy for removal of large CBD stones in Billroth II gastrectomy. METHODS: Between March 2010 and February 2011, one-step EPBD under cap-fitted forward-viewing endoscopy was performed in patients who had undergone Billroth II gastrectomy at two tertiary referral centers. Main outcome measurements were successful duct clearance and EPBD-related complications. RESULTS: Successful access to major duodenal papilla was performed in 13 patients, but successful selective CBD cannulation was achieved in 12 patients (92.3%). Median maximum transverse stone size was 11.5 mm (10 to 14 mm). The mean number of stones was 2 (1-5). The median CBD diameter was 15 mm (12 to 19 mm). Mean procedure time from successful biliary access to complete stone removal was 17.8 min. Complete duct clearance was achieved in all patients. Four patients (33.3%) needed one more session of ERCP for removal of remnant stones. Asymptomatic hyperamylasemia in two patients and minor bleeding in another occurred. CONCLUSIONS: Without preceding sphincterotomy, one-step EPBD (> or =10 mm) under cap-fitted forward-viewing endoscopy may be safe and effective for the removal of large stones (> or =10 mm) with CBD dilatation in Billroth II gastrectomy.
