Ranula is a mucosal cyst that occurs in the mouth floor. This is a pseudo cyst caused by mucous retention within the tissue due to the rupture of catheter in the salivary gland. Ranula occurs mainly in a unilateral form and is characterized by painless bluish transparent swelling, with a increasing mass size. If the size is large, it can cause discomfort during swallowing, pronounciation, and mastication, but external swelling and infection is rare. Treatments include observation for spontaneous resolution, simple incision and drainage, marsupialization and excision. Marsupialization done by removing parts of the cyst wall and connecting it to the oral mucosa. It is a conservative procedure and recommended for children. It has advantages such as maintaining outline of oral tissue and less risk of damaging anatomic structure. Recurrence is common, mostly occurring within 4 months after surgery. This case is about a eight-year-old girl with ranula on the right mouth floor. This patient was treated with marsupialization that is one of treatment for ranula, and recurrence was not observed.

Purpose: Benign bone tumor of the talar body have rarely been evaluated according to the therapeutic methods because of the scarcity of their incidence. Here, we report our experience of 8 cases who were treated by using of posterior approach and curettage through the posterior process of the talus. Materials and Methods: Between February 1986 and October 2001, we experienced 8 cases of benign bone tumor occurring in the talar body. They included two osteoid osteomas, two giant cell tumors, one capillary hemangioma, one chondroblastoma, one simple bone cyst, and one osteochondroma. Their mean age was 22.1 years (ranging from 10 to 41 years). Mean follow-up period was 7.7 years (ranging from 1 to 16 years). All patients were treated by using of posterior approach. Two osteoid osteomas and one osteochondroma were treated by excision of tumors. Other cases were treated with curettage through the cortical window on the posterior process of the talus. Results: There was no recurrence during the follow-up period. one infection occurred. Except this case, all patients had no pain in weight-bearing, and complete range of movement at the ankle joint was reserved in each case. Conclusion: In this study, we suppose that posterior approach to the talar body may be a safe method with minimal damage of normal tissues and sufficient of curettage is capable through the cortical window on the posterior process of the talus.

The purpose of this study was to determine clinical features of canine episcleritis and outcomes of therapy in Korea. The medical records of dogs with episcleritis presented at the Veterinary Medical Teaching Hospital of Seoul National University from January 2006 to December 2007 were reviewed. Episcleritis was diagnosed in 17 eyes of 12 dogs. The most frequently affected breed was Shih Tzu (n = 6). The median affected age was 5 years with a range from 3 years to 12 years. Simple episcleritis was identified in 8 dogs, nodular granulomatous episcleritis (NGE) in 3 dogs, and secondary episcleritis caused by panophthalmitis in a dog. The combination immunosuppressive therapy of topical corticosteroids, topical cyclosporine A, and intralesional injection of triamcinolone (4 mg) and gentamicin (4 mg) was performed. Most of the patients with episcleritis were resolved within 30 days following the therapy. Surgical excision was performed in 1 NGE case which was not responded to the medical therapy. Recurrence was observed in 4 dogs between 5 and 8 months after the first visit. It is considered that strong immunosuppressive therapy and periodic ocular examination are needed to control episcleritis.

Congenital duodenal obstruction in the newborn infant may be due to a variety of causes. Duodenal obstruction often presents with bilious vomiting and upper abdominal distention. Diagnosis is usually established on plain x-ray of the abdomen by the classic finding of the double-bubble. In the period July 1986 to June 1990, 16 patients with congenital duodenal obstruction were operated and the following results were obtained. 1. Sixteen patients were comprised of 11 males and 5 females, the ratio of male and female was 2.2:1. 2. Thirteen patients(81%) had been admitted to our hospital during one month of life. 3. Congenital duodenal obstruction was in 16 cases; malrotation in eight(50%), annular pancreas in six(38%), type 1 atresia in one(6%), and wind-sock anomaly in one(6%). 4. There were two premature patients and six patients of small for gestational age. 5. Overall, bilious vomiting, occurring in three fourths, was the single most frequent presenting complaint. 6. Polyhydramnios occurred in two of the patients. 7. Diagnosis was possible with clinical symptom and simple abdomen. 8. The operative procedures performed were ; duodenoduodenostomy in five, duodenojejunostomy in two, excision of wind-sock membrane in one, and Ladd's procedure in eight. 9. A total of ten asociated congenital anomalies were found in six patients. 10. Postoperative complications occurred in five cases(31%).

A 30-year-old woman who was diagnosed as peripheral neuroblastoma by fine needle aspiration of a soft mass of the right upper arm is described. She presented a slowly growing, soft mass of the right upper arm for 1 month. The right humerus revealed no abnormal finding on X-ray. Ultrasonogram of the right upper arm revealed a well demarcated, smooth marginated solid mass without invasion of adjacent structures. Fine needle aspiration was done under the impression of soft tissue tumor with undetermined biologic behavior. The aspirates were highly cellular and the tumor cells were dispersed both singly and in clusters of varying size. The clusters occasionally showed a central capillary core and rosette-like structures. The tumor cells were small in size and had a small to medium amount of cytoplasm. Some of them revealed slender cytoplasmic processes. The nuclei showed distinct nuclear membranes, finely clumped chromatin and small conspicuous nucleoli. Cellular pleomorphism or mitotic figure was not definite. These cytologic findings were interpreted as a malignant, non-lymphomatous small round cell tumor, most likely representing peripheral neuroblastoma or Ewing's sarcoma. Final diagnosis was confirmed by simple excision as peripheral neuroblastoma.

Purpose: Radical surgical extirpation in advanced breast cancer patients produces extensive loss of skin with large defects requiring plastic surgical procedures for the closure. Many reconstructive methods exist, the choice of which depends upon the characteristic of the wound, extent of resection and patient comorbidities. For adequate coverage of the large skin defects following resection of advanced breast cancer, current authors have performed a thoracoabdominal flap. Methods: From August 2008 to June 2009, 4 cases of thoraco-abdominal flap were performed for chest wall reconstruction after mastectomy of advanced breast cancer. Flap dissection was entirely performed in a subfascial plane and the flap involving the external oblique abdominal muscle. The flap was rotated clockwise in left chest wall defects and counterclockwise in right chest defects and the donor site was closed directly. Results: Their mean age, 55.7 years and the average follow-up interval was 9 months. Patients' oncologic status ranged from stage IIIc to stage IV, it was classified according to the TNM staging system. Flap dimensions ranged between $15{\times}15$ and $25{\times}25\;cm$. One flap sustained a partial loss at the distal margin and revision with pectoralis major musculocutaneous island flap. Conclusion: Large chest wall reconstructions are usually required after radical excision of advanced cancer stages patients with poor general conditions. Thoracoabdominal flap is a simple, quick single-stage procedure, and offer to patient fast recovery, low complication rate, enabling further concomitant adjuvant therapy.

Purpose: The purpose of this study was to evaluate the radiologic features of juxtafacet cyst and determine the correlation between these features and clinical outcome. Materials and Methods: We analyzed a total of 23 patients. The degree of facet joint degeneration was classified using the Fujiwara method. The facet joint angles were measured with an magnetic resonance imaging to determine whether there was a difference between the cystic lesion that was occupied and the cystic lesion that was not occupied. Disc degeneration was measured by the Pfirrmann classification method. The clinical result was evaluated using the Oswestry disability index score and visual analogue scale. Results: The L4-5 level of juxtafacet cyst was mostly affected, as found in previous studies. Facet joint arthritis was more severe within the side with the cystic lesion. Significant correlation was found between disc degeneration and juxtafacet joint cyst. All patients underwent wide decompression and fusion. Clinical result was excellent. No patients had signs of recurrence during the follow-up periods. Conclusion: Juxtafacet cyst has a significant correlation with facet joint degeneration. Therefore, aggressive surgical treatment-not just simple cyst excision-should be considered as the treatment option for juxtafacet cyst associated with degenerative lumbar disease.

Background Dupuytren's disease decreases quality of life significantly and often requires surgical treatment, nevertheless there is no actual gold standard. The aim of this study was to introduce the use of minimally invasive pull-through technique. Methods From 2016 to 2020, 52 patients suffering from Dupuytren's contracture were treated with the minimally invasive pull-through technique. We evaluated the improvement in range of motion, pain, disability, and quality of life in the long term. Total extension deficit, quick disabilities of the arm, shoulder, and hand (QuickDASH), and EuroQol five dimensions-five levels index were systematically scored before each surgical intervention and reevaluated after 24 months. Results Fourteen patients (26.9%) had already received a previous intervention (percutaneous needle aponeurotomy or collagenase Clostridium histolyticum). The mean preoperative total active extension deficit was 84.0 ± 23.3 degrees (55-130 degrees). Mean follow-up was 36 months. There were no cases of tendon rupture or neurovascular injury. Total active extension deficit at the final follow-up was 3.4 ± 2.3 degrees (0-12 degrees). The mean active range of motion of the MCP and PIP joints were, respectively, 90.5 ± 3.3 degrees (85-96 degrees) and 82.7 ± 2.5 degrees (80-87 degrees). At 24 months after cord excision, a mean 10.7 points improvement in the QuickDASH questionnaire was registered (p < 0.001). Pull-through technique was equally effective both on patients with a primary or a recurrent disease. Eight patients (15.4%) had a recurrence of disease in the metacarpophalangeal joint or proximal interphalangeal joint. Conclusion The pull-through technique is a simple, accessible, and effective technique for the treatment of Dupuytren's contracture. The use of palmar mini-incisions combined with minimal dissection has a low risk of iatrogenic injury to the neurovascular bundles and tendons, and has a low risk of recurrence rate. This study reflects level of evidence IV.

Background: The reciptents of aortic valve replacement or a Bentall operation usually display various degrees of mitral regurgitation. When deciding whether or not to correct the mitral regurgitation, one must consider its severity, underlying causes and operative risk. Recently, the operation method for correcting the concomitant mitral regurgitation has been done through aortic root to reduce the operation time and the cardiac trauma. We report our experiences that transaortic mitral valve commissuroplasty done with aortic valve replacement or a Bentall operation has been a simple, less invasive, effective method in the operative management of mitral valve regurgitation without significant organic changes. Material and Method: Between June 2002 and June 2005, twenty patients under-went mitral valve commissuroplasty via the aortic root with aortic valve replacement (n=14) or a Bentall operation (n=7). The mitral valve regurgitation of the patients didn't exceed a moderate (grade 2) degree and there was no significant organic disease. The preoperative diagnosis of MR was established by TTE and intraoperative TEE, and the patients were followed postoperatively by TTE. The operative technique was a simple anterolateral commissuroplasty of the mitral valve with a single mattress suture via the transaortic annular approach after excision of the aortic valve leaflets. Result: The mean patient age was 56.2 years and 65% (n=13) were male. The preoperative MR was mild (grade 1) in 9 (45%), mild to moderate in 8 (40%), and moderate (grade 2) in 3 (15%) patients. There were no operative mortalities. The MR improved in all patients (p=0.002) and the left ventricular ejection fraction (LV EF) improved in 14 (70%) patients (p=0.005). The mean cross-clamp time for the patients who under- went aortic valve replacement with transaortic mitral repair was $62.1{\pm}13.9 min$ and this was $137.5{\pm}7.2 min$ for the patients who underwent a Bentall operation with transaortic mitral repair. Conclusion: For selected patients without significant mitral organic disease, transaortic mitral valve commissuroplasty combined with aortic valve replacement or a Bentall operation may be a feasible, effective method without adding significant aortic cross clamping time and more cardiotomy.

Background: Congenital cystic diseases of the lung are uncommon, and they share similar embryogenic and clinical characteristics. But they are sometimes vary widely in their presentation and severity. Therefore they are often difficult to make different diagnosis each other, and all require surgical treatment. Material and Method: From 1993 to 2006, 38 patients underwent surgical procedures under these diagnostic categories in the Depart. of Thoracic and. Cardiovascular Surgery, Busan-Paik Hospital, College of Medicine, Inje University. And we retrospectively reviewed these patients' charts for clinical presentations, surgical procedures, pathologic findings and postoperative morbidity and mortality. Result: There were 22 males and 16 females, ages ranged from 1 month after birth to 51 years and mean age was 20.8 years. The main symptoms were 19 fever, cough, sputum production due to recurrent infection, 7 dyspnea, 8 chest discomfort, 4 hemoptysis, but eight patients were asymptomatic. Computed tomography was chosen as diagnostic modalities and available for operation plan for all of patients. For all the cases, surgical resection were performed. Lobectomy was performed in 28 patients, simple excision (resection) in 8 patients, segmentectomy or wedge resection in 2 patients. There were 10 pulmonary sequestrations, 15 congenital cystic adenomatoid malformations (CCAM), 11 bronchogenic cysts, and 2 congenital lobar emphysemas. They all were confirmed by pathologic exams. The complications were 6 wound disruption or infection, 2 chylothorax, 1 ulnar neuropathy, but all of them were resolved uneventful. There was no persistent air leakage, respiratory failure, operative mortality and recurrence. Conclusion: We performed immediate surgical removal of congenital cystic lung lesions after diagnosis and obtained good results, so reported them with literature review.
