Pleomorphic adenoma (PA) is a commonly occurring benign tumor originating in the salivary glands. The incidence is mostly in the parotid glands (85%) followed by minor salivary glands (10%). Pleomorphic adenoma from minor salivary glands of the lips is a rare neoplasm. Here, we present a case of a patient with PA in the upper lip, reporting a common neoplasm in a rare site. A 82-year-old male with a slowly progressing swelling that occurred 20years ago on the upper white lip. This tumor is not associated with pain and tenderness. The mass was about 1.5x1.5cm sized, circumscribed, sessile and firm on the external upper lip without oral side bulging (Fig. 1). The tumor was removed completely with a elliptical incision under local anesthesia. The encapsulated mass was measured 0.9x0.9x0.6cm. On histology, a well-circumscribed growth was seen comprising epithelial and stromal components. The epithelial component formed glandular structures lined by round-to oval cells having small nuclei, pink cytoplasm and myoepithelial basal cell layer while the stroma had a fibromyxoid appearance(Fig. 2). Postoperatively wound was well healed without recurrence after 6months. Pleomorphic adenoma of the upper lip is a rare neoplasm, especially not intraoral growth. For aesthetic good result, the mass was removed without hesitation. It is required a high index of suspicion and a long-term follow-up because it could recur and rarely be transformed into malignancy.

While simultaneous bilateral partial nephrectomy with a conventional multiport robot has been consistently reported since the 2010s, the introduction of the DaVinci SP system (Intuitive Surgical, Sunnyvale, CA, USA) could provide a novel way to perform surgery on bilateral kidneys while innovatively reducing the number of incisions. In our first report worldwide, the patient with bilateral small renal mass (2.0 cm for the left and 1.5 cm for the right side) and preoperative normal renal function was placed in the lateral decubitus position on an inverted bed. After tilting the bed to be as horizontal as possible, a 4-cm incision was made in the lower part of the umbilicus for the floating trocar technique. The partial nephrectomy was performed reliably as with the conventional transperitoneal approach, and then the patient could be repositioned to the contralateral side for the same procedure, maintaining all trocars. Total operation time (skin to skin), total console time, and the left- and right-side warm ischemic times were 260, 164, 27, and 23 minutes, respectively, without applying the early declamping technique. The estimated blood loss was 200 mL. The serum creatinine right after the operation, on the first day, 3 days, and 90 days after surgery were 0.92, 0.77, 0.79, and 0.81 mg/dL, respectively. For 90 days after the procedure, no complications or radiologic recurrence were observed. Further clinical studies will reveal the advantages of using the DaVinci SP device for this procedure over traditional multiport surgery, maximizing the benefit of a single port-based approach.

Purpose : We report a result of arthroscopic treatment of the recurrent prepatellar bursitis. Materials and Methods : Between March 2001 and May 2002, we treated 4 patients with prepatellar bursitis, the average follow-up period was 14.5 months. The causes were acute trauma 3 cases and repeated minor trauma 1 case. All cases were recurred after previous history of the conservative therapy at other hospital but one was a recurred case after operative excision. Operative technique was as follows. Before inserting the arthroscope, the bursa was inflated with saline. The portals fur 4 mm diameter arthroscope were placed 1cm away from the bursal sac through small skin incision. Superficial layer of the bursa was resected first and then deep portion was the next. Several percutaneous mattress sutures were applied to the overlying skin with deep tissue, and compressive dressing was applied and maintained for 2 weeks. Results : All 4 cases were no recurrence, no pain, no tenderness. The results were considered satisfactory, Two cases of mild skin dimpling at suture site were observed. Conclusion : Arthroscopic treatment of the prepatellar bursitis is an another method of operation technique fur recurrent prepatellar bursitis, however long term follow-up will be needed about recurrence.

The term 'myositis ossificans' encompasses four categories of clinicopathological disorders. The first, myositis ossificans progressive(fibrodysplasia ossificans progressive), is a rare genetic disease characterized by progressive heterotopic ossification involving skeletal muscle, tendon, ligaments, and fascia, with congenital malformation of the great toes, and usually microdactyly, monophalangism, and mal formed proximal phalanges. with valgus deformity of metatarsophalangeal joint. The ossification begins shortly after birth and may contribute to the patient's death. The second, heterotopic ossificans, can occur in patients with neuromuscular and chronic diseases such as paraplegia, poliomyelitis, polymyositis, bum, tetanus, and infection. But the lesions in these cases often lack the typical histologic features of myositis ossificans. The third, myositis ossificans traumatica, is the most common; it develops in response to soft tissue trauma such as a single severe injury, minor repetitive injures, fracture, joint dislocation, stab wound, or surgical incision. The forth, nontraumatic myositis ossificans, also designated :pseudomalignant osseous tumors of extraskeletal soft tissues' and 'psedomalignant myositis ossificans', occurs in persons repeated small mechanical injures or nonmechanical soft tissue injuries due to local ischemia, inflammation. or other factors cannot be ruled out in such cases.

Background: Adequate exposure of the mitral valve is a prerequisite for mitral procedures including the repair. An extended transseptal approach in mitral valvular operations is known to have certain technical advantages in recent years because of the anatomic posterior location of the mitral valve, especially in reoperations and in the presence of the small atrium in spite of the possibility of arrhythmia due to injury of sinus nodal artery. Material and Method: We compared the preoperative status, operative, and postoperative factors among patients in two study groups, transseptal only (Group I, n=10) and extended transseptal approach(Group II, n=25). Result: There were no differences in age, sex, NYHA functional class, left atrial size, and left ventricular function. The incidence of the redo-operation was high and early postoperative arrhythmia, which was improved later, appeared in 3 patients in Group II, but not in Group I. Conclusion: We believe that atrial septal incision could be extended up to the atrial roof whenever exposure of the mitral valve during a transseptal approach is inadequate because the late results were similar.

Few observation have been made on the pericardial pressure and little is known about the composition of he pericardial fluid. So we studied the basic qualitative and quantitative analysis of the pericardial fluid in the patients with cardiac disease either congenital heart diasese(group A) or acquired heart disease(group B). The pressure of the pericardial cavity was measured by the method of open tipped water filled small polyethylene catheter connecting to the standardized monitor, which was introduced into pericardium of the patients who were performed pericardial incision for the heart or pericardial surgery. All of the data was compared to the simultaneously checked hematologic value of the same patient. The mean pressure of the pericardial cavity was 2.4mmHg and the amount of the pericardial fluid was 13cc/m2 of body surface for the group A and 17.7cc for the group B. And the cell count was 138$\pm$l16/1 in group A and 230$\pm$135/1 in group B and the pH was 7.83$\pm$0.40 in group A. 7.80$\pm$0.52 in group B. Pericardial fluid revealed satisfactically significant alkaline pH than plasma. The fundamental electrolyte, Wa+, K+, Cl and glucose were identical to the hematologic values of the same patient, but the protein concentration was 2.Bg/dL for group A and 3.Ig/dL for group B heart disease and those were remarkable low concentration compared to the hematologic value of the same patient. LDH and amylase were identical to the value of the serum of the same patient, but the concentration of LDH of group B was slightly higher than that of the group A.

This study is to provide evidence-based recommendations for the most-effective treatments of benign prostatic hyperplasia based on patient preference or clinical need, and to meta-analyze the Korean literatures for the development of BPH treatment guidelines. For these analyses, extensive literature searches (208 articles), with priority given to the Korean Journal of Urology, were conducted from 1960 to August, 1996. Meta-analysis, like all statistical analysis, has two main functions: data summarization (qualitative meta-analysis) and smoothing o. pattern recognition (quantitative meta-analysis). As well, critical reviews and syntheses with the mean and 90-percent confidence intervals for the likelihood were used to evaluate empirical evidence and significant outcomes of the BPH treatment literatures (106 articles). For this task, the Methodologic Panel for BPH Guidelines was composed of multidisciplinary experts in the field. The results of the study were summarized as follows: For all that watchful waiting is an appropriate treatment strategy for the majority of patients with prostatism, we couldn't find the Korean literatures which carried this article. The literatures on alpha-1-adrenergic receptor blockers provide no evidence to suggest that any one alpha blocker is more effective than another. The finasteride reduces the size of the prostate, on average, and leads to a small yet perceptible reduction in sysptoms. Of all treatment options, prostate surgery with transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), and so on, offers the best chance for symptom improvement. However, surgery also has the highest rates of significant complications. Therefore, surgery need not always be a treatment of last resort. Balloon dilation of the prostatic urethra is clearly less effective than surgery in relieving symptoms, but it is associated with fewer complications. Emerging technologies for treating BPH include lasers, coils, stents, thermal therapy and hyperthermia. Established technologies will also be reanalyzed as results of new trials are reported. Although this study has some limitations due to lacking for good quality literatures, ' it provides a cornerstone for our medical research. It represents the most current scientific knowledge regarding the clinical epidemiology including treatment of BPH. It will be revised and updated as needed.

Purpose: A large defect by fourth-degree burns in the upper limb requires flap reconstruction. Since severe vascular damage and decrease in blood circulation after vascular anastomosis can occur in defects caused by fourth-degree burns. Because of the disadvantages, it is difficult to apply free flap surgery to fourth-degree burns. We reconstructed a upper extremity using the pedicled Latissimus Dorsi (LD) flap in two stages. The purpose of our study is to review our experience and suggest two-staged pedicled Latissimus Dorsi (LD) flap in fourth-degree burns of upper extremities. Methods: A retrospective review was performed from 2016 to 2019, on a total of 12 fourth-degree burn patients undergone two-staged pedicled LD flap surgery as reconstruction of upper extremities in our hospital. We reviewed the location of the injury, etiology, TBSA (%), size of burns requiring flap surgery, period from 1st surgery to secondary division surgery, complications. Results: Using two-staged LD flap as a primary reconstruction, the outcome is satisfactory. This flap preserves the elbow joint and maintains the length of the forearm. We obtain low donor-site morbidity, simplicity and a small incision in the donor site. Conclusion: Using two-staged LD flap in fourth-degree burns of upper extremity is effective, such as preserving elbow joint and maintaining the length of the forearm. Successful reconstruction was achieved with excellent cosmetic results with reducing a postoperative scar, donor-site morbidity. Due to these advantages, two-staged pedicled LD flap can be an optimal option for reconstruction of fourth-degree burns in the upper limb.

Purpose: The circular stapled Billroth I gastrectomy has been gradually popularized because of several advantages. Thus, this study aims to identify what to be supplemented for the safety of this technique by examining the potential complication after the circular stapled Billroth I gastrectomy. Materials and Methods: This study selected 594 patients who underwent the circular stapled Billroth I gastrectomy because of the gastric cancer in our department of surgery from Jan. 1998 to Dec. 2004 as the subjects. As of Jan. 2001 when the bleeding on the anastomosis site was visually checked through the small incision at the opposite curvature to the lesion of the stomach to be resected and so the operation was completed, the patients were divided into the Group I (n=219) and Group II (n=375), which were the patients before and after Jan. 2001, respectively. Then, the clinical characteristics and postoperative anastomotic complications of both groups were compared. Results: For the comparison of complications between two groups, the anastomotic leakage was found in four cases in Group I and three cases in Group II (p=0.196). The stenosis on the anastomosis region was not observed in both groups. The bleeding on the anastomosis region illustrates the statistically significant difference between Group I and Group II, with 43 cases and 2 cases, respectively (P=0.0019). Conclusion: The circular stapled Billroth I gastrectomy is recommended because of several advantages of this technique. However, the bleeding on the anastomosis site may be indicated as the critical issue. Accordingly, the visual check on the bleeding on the anastomosis site during the operation will improve the safety of circular stapler.

Previously, we have shown that green tea extract lowers the intestinal absorption of cholesterol, fat, and other fat-soluble compounds. We conducted this study to determine whether green tea extract affects the rate of $^{14}C$-oleic acid esterification into various lipids in the intestinal mucosa of rats. Male Sprague-Dawley ruts were had free access to a nutritionally adequate AIN-93G diet and deionized water. Initially, the rat's mucosal content of total lipids was measured following 1 mL olive oil administration with (green tea group) or without (control group) 100 mg green tea extract powder. At 1 h and 5 h, intestinal segments were extracted for total lipid analysis. Secondly, to measure mucosal esterification rates of lipids, an abdominal incision was made along the midline, and a 10-cm long jejunal segment of the small intestine was ligated in situ. Then, micellar solutions with or without green tea extract were injected into the ligated jejunal segments and incubated for 10 mill. The micellar solution contained $200.0\;{\mu}$ Ci $^{14}C$-oleic acid, $200.1\;{\mu}mol$ unlabelled oleic acid, $66.7\;{\mu}mol$ 2-monooleoylglycerol, $66.7\;{\mu}mol$ palmitoyl-sn-glycero-3-phosphocholine, 2.2 mmol glucose, $50.0\;{\mu}mol$ albumin, and 16.5 mmol Na-taurocholate per L of phosphate buffered saline (pH, 6.3) with or without 8.87 g green tea extract powder. At 10 min, each rat was sacrificed by cervical dislocation under anesthesia and the segment was removed for lipid analysis. Significant differences were observed in mucosal triglyceride content at 1 h and 5 h in ruts given green tea extract. Significant differences in the rate of $^{14}C$-oleic acid esterification into triglycerides and phospholipids fractions were observed between control and green tea groups. However, There were no significant differences in other lipid fractions. These results indicate that the lowered esterification rates of $^{14}C$-oleic acid into triglycerides and phospholipids fractions is attributable to presence of green tea extract. This may be associated with an inhibitory effect of green tea catechin on the mucosal processes of lipids, leading to the inhibition of intestinal absorption of lipids.
