BACKGROUND AND OBJECTIVES: Though the surgical intervention of subclavian artery stenosis has been effective, its high morbidity and mortality have limited its clinical application. In 1980 percutaneous balloon angioplasty of stenotic artery was introduced as a substitute for surgical intervention and subsequent reports have supported its efficacy noting that it is more effective when combined with stent. The purpose of this study was to assess the feasibility, safety, and efficacy of percutaneous intervention as an alternative or primary therapy for symptomatic subclavian artery stenosis. METHODS: Between September 1993 and October 1998, 17 lesions in 16 patients of symptomatic subclavian artery stenosis were enrolled as candidates for nonsurgical intervention. We performed percutaneous balloon angioplasty with stenting to the subclavian artery stenosis and evaluated the early results. RESULTS: 1)The patients had a mean age of 55+/-14 years and 13 of 16 patients were male. 2)Subclavian artery stenting was successful in 94% (16/17) of the lesion without significant complications. The cause of failure was suboptimal result after deployment of stent. 3)The types of stents deployed were Strecker stents in 4, Palmaz stents in 8, Wall stents in 3 and Jo stents in 2 cases. 4)The peak and mean pressure gradient reduced from 58.5+/-17.0 to 8.5+/-7.4 and 31.4+/-13.0 to 4.7+/-5.5 mmHg respectively (p<0.01) and the degree of luminal stenosis decreased from 92.5+/-8.5% to 10.0+/-14.3%. (p<0.01) CONCLUSION: Subclavian artery stenosis can be managed safely and effectively through percutaneous balloon angioplasty with stenting, with an excellent technical success rate and less morbidity and mortality particularly in patients coexisting other vascular and systemic diseases. However, the long-term patency and clinical effects should be warranted.

BACKGROUND: Proximal humerus fracture is considered to be the third most common fracture for patients aged 65 years or older. Conservative treatment has been known to treat most of humerus fracture. However, fractures with severe displacement or dislocation may require surgical treatment. Intramedullary fibular allograft with a locking plate is frequently used in patients accompanying medial metaphyseal disruption. In this study, author intends to evaluate clinical and imaging results based on patients who underwent surgical treatment using fibular allograft with a locking plate. METHODS: This study is conducted prospectively at Wonju Severance Christian Hospital, targeting patients who previously underwent surgical treatment using open reduction and intramedullary fibular allograft with a locking plate between 2011 and 2015. A total of 26 patients were evaluated on the following: postoperational clinical assessment measuring Constant score, American Shoulder and Elbow Society (ASES) score, and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Postoperational imaging assessments are evaluated via measuring the neck-shaft angle. The study subject were Neer classification type 3, 4 proximal humerus fracture cases with disrupted medial hinge and having cortical comminution in the region of the surgical neck. RESULTS: The average period of progression was 22.5 months, and the average age of patients was 72.6 years. At the final follow-up, the average Constant, average ASES, and average DASH scores were 80.1, 78.5, and 20.6 respectively. The average neck-shaft angle was 127.5°. CONCLUSIONS: In conclusion, fibular allograft augmentation with a locking plate showed satisfying results in both clinical and imaging studies.

BACKGROUND: The purpose of this study is to administer conservative treatment in 30 patients diagnosed with idiopathic frozen shoulder, following the suggested frozen shoulder rehabilitation program and to assess the clinical outcome using a prospective study. METHODS: Thirty patients diagnosed with idiopathic frozen shoulder, treated with steroid hormone injection on the articular joint with an intra-articular steroid (triamcinolone 40 mg + lidocaine 4 ml) injection and started on stepwise shoulder extension exercise were chosen. The subjects were divided into two groups of 15 people each with one group undergoing rehabilitation with continuous passive motion (CPM) and the other group without it. Follow-ups were done before rehabilitation and at 4-week intervals with the 24th being the final week. At every follow-up, passive range of motion (ROM) was measured and surveys on pain and clinical score were administered. RESULTS: In the last follow-up, both groups showed statistically significant improvements in all evaluation criteria. However, no statistical difference in all values of the ROM and Constant score evaluation criteria was observed between the groups. Only in the last follow-up, group 1 had a visual analog scale (VAS) score of 2.4 +/- 2.1 points, which was lower, with statistical significance, than the VAS score of group 2, which was 4.4 +/- 3.1 points (p<0.001). CONCLUSIONS: Study using CPM in treatment of frozen shoulder has been inadequate, meaning that there is still room for improvement and need for more study on setting a more specific protocol and guidelines for this procedure.

Ampullary adenoma is a very rare tumor and it is truly a premalignant neoplasm. The current methods of endoscopic biopsy and even intraoperative frozen sections are limited in their ability to rule out coexisting foci of carcinoma. So, complete removal should be obtained for the treatment of ampullary tumor. Physicians can select one of the treatment modalities, including endoscopic papillectomy, transduodenal local resection and pancreaticoduodenectomy, according to the tumor size and the co-existence of severe dysplasia, carcinoma in situ or adenocarcinoma, and the patient's medical illness. Endoscopic papillectomy can be done in the case of a small adenoma. Pancreaticoduodenectomy is now a standard treatment for a large adenoma and also adenoma with carcinoma. From the view point of organ preservation and long-term quality of life, determining the adequate indications for performing transduodenal local resection for large ampullary adenoma and adenoma with carcinoma should be done.

Eighty seven cases of ocular adnexal tumors were excised and studied histologically between January 1, 1967 and March 31,1974 at Department of Ophthalmology, Dong San Presbyterian Medical Center. The incidence of ocular adnexal tumors among 22,420 out-patients was 0.38%. The Sexual distribution revealed 49 males (56.3%) and 38 females (43.7%). The benign tumors were more frequent in 2nd and 3rd decades, but the malignant tumors, on the other hand, after 5th decade. Location-wise, the eye-lid was largest in number (38 cases, 43.7%) followed by the conjunctiva (24 cases, 27.6%), orbit (23 cases, 26.4%) and lacrmal apparatus (2 cases, 2.3%) in order. As asingle disease, the nevus, pseudotumor and malignant melanoma were impressively high in incidence. Over all incidence of malignant tumors was 31% (27 cases) and that of benign tumors 69% (60 cases). Of malignant tumors the eye lid tumors were largest in number (12 cases), the orbit 9 cases and conjunctiva 6 cases.

A pancreatic pseudocyst is the most common cystic lesion in the pancreas encountered in the clinical practice. The management of pancreatic pseudocyst is a complex and prolonged problem for the general surgeon. Especially, considerable ambiguity exists regarding both the incidence for surgery and the timing of operative intervention in patients with pancreatic pseudocysts. The clinical courses of 50 patients with pancreatic pseudocysts were retrospectively reviewed in the Department of Surgery at Young Dong Severance Hospital during the period of 10 years from March 1985 to February 1995. The results were as follows: 1) The pancreatic pseudocysts were most prevalent in the 3rd and the 4th decade (58%) of age, and the male to female ratio was 3.5:1. 2) Alcoholic pancreatitis was the disease most frequently associated with pancreatic pseudocysts (44%). 3) The frequent symptoms or signs of patients of pancreatic pseudocyst were abdominal pain (84%), abdominal masses (24%), and nausea and vomiting (20%). 4) Valuable diagnostic radiologic methods were abdominal sonography (82%), abdominal CT (96%), and ERCP (80%). 5) The applied surgical methods were Roux-en-Y cystojejunostomy (37% of all surgical cases), pseudocyst resection or distal pancreatectomy (50%), and external drainage (13%).Surgical indications for the conservative management group were persistent symptoms and/ or increase in size in eleven patients (33%) and natural complications in six patients (18%). As the size of the pseudocyst increase, resolution rate tended to decrease and the complication rate tended to increase, but complete resolution occurred in 26% of the pseudocysts sized from 5 cm to 10 cm. Two pseudocysts greater than 10 cm in size were treated successfully with conservative management. We conclude that the cyst size and the cyst age are not absolute criteria for determining surgical indications.

The authors experienced a case of falciform retinal fold which occurred congenitally in the right eye of a 13 years old Korean female. This was situated in the inferior nasal quadrant in the extreme periphery of the retina and was associated with abnormal shape and position of disc and macula without foveal reflex. Visual acuity of right eye was 20/50 and refractive error was not present. We described the characteristic fundus findings of this case with brief review of relating literature.
