Background: To evaluate the success rate of balloon dilation and the factors possibly influencing the outcomes of balloon dilation for the ureteric strictured portion of ureteroureterostomy (UUS) site in patients with post-gynecologic surgeries. Methods: A single institution data base was screened for the patients who received balloon dilation for a treatment of ureteral stricture diagnosed after gynecologic surgery. Overall 114 patients underwent primary intra-operative UUS due to ureteral injury during gynecologic surgery. Among them, 102 patients received balloon dilation, and their medical records were retrospectively reviewed. Success of balloon dilation was defined as the condition that requires no further clinical interventions after 6 months from balloon dilation. Results: The ureter injury rate of women treated with open radical abdominal hysterectomy was highest (32 cases, 31.4%). 60 patients (60.8%) showed successful outcomes regarding dilation. All patients underwent technically successful dilation with a full expansion of balloon during the procedure, but 40 patients (39.2%) were clinically unsuccessful as they showed a recurrence of ureteral stricture on the previous balloon dilation site after the first dilation procedure. Univariate logistic regression analyses showed that stricture length >2 cm was a significant predictor of successful dilation (odds ratio, 0.751; 95% confidence interval, 0.634-0.901; p-value, 0.030), but it failed to achieve independent predictor status in multivariate analysis. Conclusion: Balloon dilation can an effective alternative treatment option for strictured portion of the primary UUS in post-gynecologic surgery patients when its length is <2 cm.

Tissue hyperplasia is one of the most frequently encountered complications when self-expanding metallic stents are placed in benign non-vascular luminal organ strictures, thus causing restenosis of the lumen. The investigators postulated that ionizing irradiation could be applied to prevent restenosis caused by tissue hyperplasia in non-vascular luminal organs as it reduced coronary or peripheral arterial narrowing successfully. The authors combined $\beta$-irradiation using $^{188}Re-MAG_3$ solution with balloon dilation for animal and clinical studies because this new treatment approach had the advantages such as low penetration depth of $\beta$-ray, self-centering irradiation, and mechanical effect of balloon dilation over using $\gamma$-irradiation with afterloading devices in this article, the concept and mechanism of radioisotope balloon dilation, and animal and clinical studies using radioisotope balloon dilation are reviewed.

This report describes a three-month-old Korean domestic kitten presented with dehydration and poor body condition. Physical examination revealed abdominal distension. Rectal diagnosis was unachievable due to the small rectum diameter. X-ray radiography and endoscopy confirmed presence of abdominal distension and indicated a stricture located 1.5 cm from the anus. A balloon was gently inserted into the rectum and inflated several times followed by triamcinolone injection. Four months later, same procedures were repeated. This report is the first to describe the use of balloon dilation of a rectal stricture followed by intralesional triamcinolone injection in a small cat with poor condition.

A 4 months old, intact male Shih-tzu was referred to the Veterinary Medical Teaching Hospital of Chungnam National University for evaluation of the cause of cardiac murmur and syncope. Thoracic radiography revealed right-sided cardiomegaly. Echocardiography showed marked hypertrophy of right ventricular free wall and obstruction of right ventricular outflow tract, indicating double chambered right ventricle (DCRV). The dog was medicated with atenolol and sildenafil for DCRV, however, clinical signs did not control by medication. Balloon dilation for DCRV was performed to ameliorate patient's clinical signs. The peak systolic pressure gradient across the obstruction region was decreased and clinical signs was improved by balloon dilation procedure. This is the first case report of balloon dilation for the treatment of canine DCRV in South Korea.

목 적: 소아의 선천성 및 후천성 식도 질환의 치료에 있어 내시경적 풍선 확장술의 안전성, 효과 그리고 기술적인 문제들을 평가하였다. 방 법: 1993년부터 10년 동안 선천성 및 후천성 식도 질환의 치료로 부산대학교병원 소아과에서 내시경적 풍선 확장술을 시행한 8명을 대상으로 이들의 의무 기록을 후향적으로 분석하였다. 시술은 풍선 카테터를 내시경 겸자구를 통해 삽입하여 내시경 직시 하에서 시행되었으며 최초로 사용되는 풍선의 크기는 식도의 내경과 협착 부위의 직경에 기초하여 결정하였다. 협착이 아주 심한 경우에는 먼저 유도 철선을 통과시킨 후, 유도 철선을 따라 풍선 카테터를 삽입시켰다. 풍선을 협착 부위에 위치시키고 서서히 확장하면서 목표하는 크기로 풍선이 팽창되면 1분 동안 확장된 상태를 유지하였다가 감압하여 1분 이상의 휴식을 가졌다. 확장 후 합병증이 없으면 풍선의 직경을 1 mm 간격으로 늘리면서 추가 확장하였다. 결 과: 남아가 3명, 여아가 5명이었고, 평균 연령은 4.2세였다. 8명의 환자에서 27회(환자 당 평균 3.2회)의 확장이 시행되었다. 기저 질환의 종류는 선천 성 식도 폐쇄에 대한 수술 후 발생한 식도 협착이 3예, 식도윤이 2예, 그 외 식도 무이완증, 빙초산에의한 부식성 식도염 그리고 고압성 식도 하부 괄약근이 각각 1예였다. 6~15 mm 직경의 풍선을 사용하였고, 최초 풍선의 크기는 협착의 형태와 정도에 따라 결정되었다. 합병증으로는 식도 천공과 심한 호흡 곤란이 각각 1예 있었다. 6예(75%)에서 시술 후 정상적인 음식 섭취를 보였다. 결 론: 내시경적 풍선 확장술은 소아의 선천성 및 후천성 식도 질환을 치료하는데 있어 안전하고 효과적인 방법이다.

A 6-month-old intact male Maltese dog (2.5 kg of body weight) was presented with the primary complaint of heart murmur and exercise intolerance. Diagnostic studies revealed severe pulmonic stenosis. Since the pressure gradient in stenotic pulmonic valve area was higher than 200 mmHg (maximum flow velocity = 7.1 m/s), the dog was underwent balloon valvuloplasty. With this procedure, the peak pulmonic velocity was reduced to 3.0 m/s (PG = 36 mmHg). Periodic re-evaluations performed in monthly interval revealed no further deterioration even after 4 month of procedure. This is the first case report of pulmonic stenosis fixed by non-surgical balloon valvuloplasty in Korea.

Congenital antral webs are a rare but relevant cause of gastric outlet obstruction in infants and children. The condition may lead to feeding refusal, vomiting, and poor growth. Due to the relative rarity of the disease, cases of congenital antral web are frequently misdiagnosed or diagnosed with significant delay as physicians favorably pursue diagnoses of pyloric stenosis and gastric ulcer disease, which are more prevalent. We report a case of an eight-month-old female who presented with persistent non-bilious emesis, feeding difficulties, and failure to thrive and was discovered to have an antral web. The web was successfully treated with endoscopic balloon dilation, which resolved her symptoms. Two years later, the patient remains asymptomatic and is thriving with weight at the 75th percentile for her age.

A 3-year-old chow chow dog with abdominal distention was referred to the Veterinary Teaching Hospital of Chungnam National University. The dog was diagnosed as Cor triatriatum dexter based on echocardiographic results, which demonstrated an abnormal membrane partitioning the right atrium. Echocardiography also revealed turbulent intra-atrial blood flow between the two chambers of the atrium. The dog was treated with balloon dilatation to enlarge the perforation in the abnormal membrane and to improve blood flow. As a result, although the membrane remained, increased perforation reduced the turbulent intra-atrial blood flow. Clinically the patient improved and eventually was discharged. This case is the first domestic Korean clinical veterinary report on the use of balloon valvuloplasty to treat Cor triatriatum dexter in a dog.

Over the last several decades there has been a remarkable change in the therapeutic strategy of congenital heart disease. Development of new tools and devices, accumulations of experience, technical refinement have positively affected the outcome of interventional treatment. Many procedures including atrial septostomy, balloon valvuloplasty, balloon dilation of stenotic vessel with or without stent implantation, transcatheter occlusion of abnormal vascular structure, transcatheter closure of patent arterial duct and atrial septal defect, are now performed as routine interventional procedures in many institutes. In diverse conditions, transcatheter techniques also provide complementary and additive role in combination with surgery. Intraoperative stent implantation on stenotic vessels, perventricular device insertion, and hybrid stage 1 palliative procedure for hypoplastic left heart syndrome have been employed in high risk patients for cardiac surgery with encouraging results. Transcatheter closure of ventricular septal defect has been performed safely showing comparable result with surgery. Investigational procedures such as percutaneous valve insertion and valve repair are expected to replace the role of surgery in certain group of patients in the near future. Continuous evolvement in this field will contribute to reduce the risk and suffering from congenital heart disease, while surgery will be still remained as a gold standard for significant portion of congenital heart disease.
