Balloon dilatation

Nan Lan, Bo Shen
Background: Current treatment modalities for anastomotic stricture in Crohn's disease (CD) include endoscopic balloon dilation (EBD) and surgery. We recently published a case series of inflammatory bowel disease patients treated with the novel endoscopic stricturotomy (ES). The aim of this case-control study was to compare the efficacy and safety of ES versus conventional EBD in the treatment of anastomotic strictures in CD patients. Methods: All eligible patients with CD anastomotic stricture who were treated with ES or EBD were included...

BACKGROUND: Controversy remains regarding the optimal surgical approach for children with supravalvular aortic stenosis (SVAS). METHODS: Since 1997 we have used Brom three-patch aortoplasty for patients with SVAS. We prefer computed tomography (CT) imaging for preoperative evaluation rather than cardiac catheterization as it avoids the well-known morbidity of general anesthesia. The purpose of this study was to present our intermediate-term results of this strategy...

OBJECTIVE: Although percutaneous transluminal angioplasty is an effective therapy against vascular access failure in hemodialysis patients, recurrent stenosis imposes enormous burden for hemodialysis patients. A nitinol scoring element-equipped helical balloon catheter (AngioSculpt® ) has been altered the landscape for treating several vascular diseases. It is not, however, fully elucidated whether AngioSculpt for advanced vascular access stenosis, difficult to expand by conventional balloons, successfully provides bailout angioplasty...

BACKGROUND: Bowel dilatation is a common adaptive mechanism after intestinal resection. The symptomatic dilated dysmotile duodenum is difficult to manage, since conventional bowel tailoring and lengthening techniques are potentially hazardous because of the anatomy of the duodenal blood supply, the proximity to the pancreas, and the risk of injury to the common bile duct. METHODS: A 2-month-old child with short bowel and a symptomatic massively dilated duodenum was treated with a Transverse Flap Duodenoplasty (TFD)...

BACKGROUND: Experiences of rotational atherectomy (RA) followed by drug-coated balloon (DCB) dilation alone (RA/DCB) for de novo coronary artery lesion have been limited. CASE SERIES: Case 1 (65 year-old male) with silent myocardial ischemia and hemodialysis had old anterior myocardial infarction and intact LM/LCx, and underwent RA/DCB against a diffuse calcified lesion in the proximal LAD and a tandem lesion in the proximal RCA. Case 2 (88 year-old female) with post-infarction unstable angina had severe thrombocytopenia and anemia due to myelodysplastic syndrome (platelet 6000/μL, hemoglobin 8...

Several chronic total occlusions (CTOs) may be undilatable despite successful wire passage; several techniques can be used for lesion preparation, such as high-pressure balloon inflations, rotational atherectomy laser, cutting balloon, and scoring balloons. Presence of moderate to severe calcification and lesion length over 40 mm in association with comorbidities, such as diabetes mellitus and reduced ejection fraction, may contribute to making a CTO lesion undilatable. Still, appropriate therapy selection for a patient with CTO should be individualized and procedure safety attended to...

Middle-aortic syndrome is a surgically curable cause of childhood hypertension. Open surgery is traditionally offered but with the advance of medical technology, endovascular approached is available in many country. Failure to control BP in open surgery is as low as 4.1% compares to 13% in endovascular approaches. However, mortality is 4% in open surgery almost 2 times higher than 2.3% in endovascular approach. This article presents a case of 10 years old child treated successfully without complication with endovascular balloon dilatation, as a first case of such disease in East Malaysia...

The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy...

Background and study aims  A 70-year-old-man underwent an esophagectomy and posterior mediastinal reconstruction for esophageal cancer that was curatively resected. Although the patient was allowed to eat after surgery, he repeatedly vomited after drinking water or eating meals and required continuous hospitalization. An upper gastrointestinal series and endoscopic examination revealed an obstruction due to the flexure of the gastric conduit, which was repeatedly treated with endoscopic balloon dilation. Endoscopic balloon dilation was completely ineffective, however, because the obstruction was not due to a small lumen diameter, but rather to severe flexure...

A 1-yr old female lion ( Panthera leo) was referred with a 10-mo history of dysphagia for solid food (meat), episodic regurgitation, and poor weight gain. Esophagoscopy confirmed an esophagitis (midesophagus) and a stricture estimated to be of 13 mm diameter. This was subsequently dilated using a 20-mm-diameter balloon for 2 min followed by a 35-mm achalasia balloon for 3 min. The etiology remains undetermined in spite of a thorough history. The animal progressed satisfactorily, reaching 124 kg after 1 yr and has had no further signs...

BACKGROUND: Many surgeons prefer a narrow gastrojejunostomy in gastric bypass believing that this provides greater weight loss. The question is whether the anastomosis remains at its initial diameter, whether it narrows or widens over time. This study tests the hypothesis that the initial diameter of the anastomosis varies over time. MATERIALS AND METHODS: One hundred obese had undergone surgery. Group A with anastomosis 1.5 cm wide and group B with anastomosis 3 cm wide...
