ABSTRACT
Objective To evaluate the efficacy and safety of endoscopic balloon dilation (EBD) on treatment of benign colorectal anastomotic stenosis.Methods Data of 36 patients with benign colorectal anastomotic stenosis undergoing EBD at Zhongshan Hospital from 2011 to 2015 were reviewed retrospectively.The number of dilation,complications rate,short-term effects and recurrence rate of stenosis were analyzed.Results Thirty-six patients had post-surgery anastomotic stenosis within 2-49 months (median 6 months),including 10 (27.8％) patients of grade 1 stenosis,15 (41.7％) of grade 2 stenosis,and 11 (30.5％) of grade 3 stenosis.The anastomotic distance from anus was 3-24 cm (median 6 cm).The 36 patients underwent 80 times of EBD with mean time of 2.22.Among them,69.4％ (25/36) cases received 1-2 times and 30.6％ (11/36) received 3 times or more.During the EBD operation,14 (17.5％) patients had minor bleeding,and intraoperative or postoperative perforation did not appeared.Postoperative obstructive symptoms were relieved in all patients.The anastomotic diameter was greater than 20 mm and EBD treatment was successful.Postoperative follow-up was 22-76 months (median 44 months).Four (11.1％) patients had recurrence of anastomotic benign stenosis at 7,11,18,and 63 months after the last time of EBD,respectively,and the symptoms were improved after the second treatment.Conclusion EBD is safe and effective in treating benign colorectal anastomotic stenosis,with better short-term and long-term outcomes.
ABSTRACT
Objective To study the curative effect of endoscopic dilatation in children with benign esophageal stricture. Methods 98 patients with benign esophageal stenosis from June 2013 to June 2016 were selected as the subjects of group A, group B and group C, 11 patients in group A were reflux esophageal stenosis, 43 children in group B were congenital esophageal atresia and in group C were 44 patients with chemical burn esophageal stricture. Then compare the three groups of children before the expansion of stenosis before the situation, the number of expansion and complications occurred. Results There was no significant difference in the average diameter of stenosis among the three groups (P > 0.05). The average length of the children in group C was higher than that in group A and group B, and group B was higher than group A, the difference was statistically significant (P > 0.05). The average number of expansion in group C was higher than that in group A and group B, and group B was higher than that in group A and group B higher than group A, the difference was statistically significant (P 0.05). Conclusion Endoscopic dilatation has a good clinical effect on children with benign esophageal stricture, but children with chemical burn esophageal stricture need to be expanded more often, while the complications are higher and the treatment is more difficult.
ABSTRACT
Antecedentes: las estenosis benignas, la ruptura del tracto digestivo y las fístulas digestivas son condiciones que ponen en riesgo la vida y que por lo general son tratadas quirúrgicamente. Ahora, ha surgido la colocación de stents metálicos parcial o totalmente cubiertos como una opción de manejo con mínima invasión. Se pretende determinar la efectividad clínica de un nuevo diseño de stent de nitinol totalmente cubierto para el tratamiento de las perforaciones digestivas y las fístulas anastomóticas, con especial énfasis en la evaluación de la hiperplasia reactiva. Métodos: en el período 2012-2013 se colocó un stent de nitinol autoexpandible totalmente cubierto en 15 pacientes con perforaciones benignas de esófago, fístulas anastomóticas, estenosis después de cirugía gastrointestinal alta o baja. Se utilizó un stent de mayor diámetro en su centro (20 mm) y en su porción proximal (28 mm). Se recolectaron datos demográficos, tipo de lesión, ubicación del stent y remoción, éxito clínico y complicaciones. Resultados: a un total de 15 pacientes se les puso 15 nuevos stents por fístulas anastomóticas (n = 8), estenosis esofágica (n = 2), estenosis en anastomosis colorrectal (n = 2), estenosis de anastomosis gastroyeyunal (n = 1), ruptura iatrogénica de esófago (n = 1), y estenosis pilórica (n = 1). La remoción endoscópica del stent fue exitosa en todos los pacientes, y una fue particularmente difícil por hiperplasia reactiva. El éxito clínico se logró en 9 pacientes (73%), con una media de permanencia del stent de 10 semanas (rango 7 a 12 semanas). En total, ocurrieron 7 complicaciones en 15 pacientes (47%): hiperplasia reactiva (n = 1), migración (n = 3), dolor severo (n = 2), ulceración esofágica (n = 1), y solo 1 paciente requirió cirugía después del fallo del stent. Ningún paciente falleció como consecuencia de la colocación del mismo. Conclusiones: un stent totalmente cubierto, con nuevo diseño, dejado por 10 semanas, puede ser una alternativa ...
Background: Benign stenoses, digestive tract ruptures and fistulas are conditions that endanger life and are often treated surgically. Recently, the placement of partially or fully covered metal stents has emerged as a minimally invasive treatment option. This article looks at a new design for stents to determine its clinical effectiveness. The new stent is a completely covered nitinol stent for treatment of gastrointestinal perforations and anastomotic leaks. This article places special emphasis on evaluating reactive hyperplasia. Methods: Fifteen had the new completely covered self-expanding nitinol stent placed for treatment of benign esophageal perforations, anastomotic leaks, and stenoses following upper or lower gastrointestinal surgery during 2012 and 2013. The stents are 20 mm in diameter in the middle and 28 mm in diameter at the proximal end. Information about patient demographics, type of lesion, lesion locations, stent removal, clinical success and complications was collected. Results: A total of 15 stents were placed in 15 patients to treat anastomotic leaks (n = 8), esophageal stenoses (n = 2), colorectal stenoses (n = 2), a gastrojejunostomy stenosis (n = 1), an esophageal iatrogenic rupture (n = 1), and a pyloric stenosis (n = 1). Endoscopic removal of the stent was successful in all patients. Although it was particularly difficult in one case because of reactive hyperplasia. Clinical success was achieved in nine patients (73%). Average duration of time between stent placement and removal was 10 weeks with a range of 7 to 12 weeks. In total, seven complications occurred in 15 patients (47%): reactive hyperplasia (n = 1), migration (n = 3) severe pain (n = 2) esophageal ulceration (n = 1) only one patient required surgery after stent failure. No patients died as the result of stenting. Conclusions: A redesigned completely covered stent kept in place for 10 weeks may be an alternative to surgery for treating gastrointestinal ...
