PURPOSE: To compare standard laparoscopy-assisted Billroth I gastrectomies including standard lymph node dissection (LABIG) with hand-assisted laparoscopic surgery with the HandPort system (HALS) for the removal of early gastric cancers (EGC). METHODS: A prospective study was performed on 26 patients of EGC at Ewha Womans University Mok-Dong Hospital from July 1999 to August 2001. Seventeen patients (Group L) received LABIG using conventional laparoscopy-assisted methods and 9 patients received LABIG using HALS (Group H). We used staplers for the anastomosis, and a standard D2 lymph node dissection was done with ultrasonic shears or electrocautery. RESULTS: In group L, pathologic reports revealed 14 EGC (stage IA 14 cases), and 3 pm cancers (stage IB 1 case, II 2 cases). In group H, there were 9 early gastric cancers (stage IA 8 cases, IB 1 case). Significant differences (P<0.05) were present between group L and H in regards to the number of harvested lymph nodes (30.8 vs 18.9), estimated blood loss (462.1 vs 286.7 ml) and postoperative transfusion amounts (0.59 vs 0 unit). There were no differences in the mean operating time, distance from the lesion to the resection margin, postoperative leukocyte count, frequencies for pain control, wound size, time to diet, weight loss, serum protein, and postoperative hospital stay. Complications were present in 1 case in group L (enterocutaneous fistula) and 1 case in group H (gastric atony). There was one conversion to open surgery in group H. CONCLUSION: LABIG including standard lymph node dissections with both standard laparoscopic surgery and HALS were performed with equal outcome. The choice of surgical method depends on the characteristics of the lesion and the patient's physical factors.

PURPOSE: This descriptive study was conducted to identify the level of knowledge of stroke symptoms and risk factors among older adults. METHODS: A total of 200 older adults over 65 years of age were conveniently recruited from out patient departments of two hospitals and a health care center from October to November 2008. The level of knowledge was assessed using both open-ended questions and a structured questionnaire based on semi-structured interviews. Data were analyzed by t-tests and ANOVA using the SPSS program. RESULTS: 52.5% of the sample had hypertension and 30% had diabetes. The mean knowledge scores for symptoms and risk factors were 8.4 +/- 3.1(out of 15) and 9.5 +/- 3.9 (out of 16), respectively. The older adults who had lower education, lower family income, and who lived in rural areas were more likely to have less knowledge of stroke symptom and risk factors(p < .05). There was no significant knowledge difference between the older adults who had at least one risk factor and those who had no risk factor for stroke. CONCLUSIONS: Educational intervention should be focused on informing older adults who are at risk for stroke about the early symptoms and management of risk factors, especially those who have low education and low social status.

Simple or unicameral bone cysts are metaphyseal lesions of long bones. They usually move away from the physiswith growth to become diaphyseal in location. Involvement of the physis and epiphysis by these cystic lesions isvery rare. This paper reports a case of simple bone cyst of the proximal humerus in a 11- year -old girl which wasshown by MR imaging to extend through the physis into the epiphysis.

OBJECTIVES: A non-progressive and conductive hearing loss with normal eardrum, but no history of trauma and infection, is highly suggestive of a congenital ossicular malformation. Among ossicular anomalies, stapes anomaly is the most common. The purpose of this study is to describe patterns of stapes anomaly and to analyze its surgical outcome with special reference to its patterns. METHODS: We conducted a retrospective case review. The subjects comprised 66 patients (76 ears) who were decisively confirmed by the exploratory tympanotomy as congenital stapes anomalies without any anomalies of the tympanic membrane and external auditory canal. The preoperative and postoperative audiological findings, temporal bone computed tomography scan, and operative findings were analyzed. RESULTS: There were 16 anomalous patterns of stapes among which footplate fixation was the most common anomaly. These 16 patterns were classified into 4 types according to the status of stapes footplate. Successful hearing gain was achieved in 51 out of 76 ears (67.1%) after surgical treatment. CONCLUSION: Footplate fixation was usually bilateral, whereas stapes anomalies associated with other ossicular anomaly were usually unilateral. The success of the surgical treatment of stapes anomaly might depend on its developmental status of the footplate. Stapes anomalies were detected without any fixed patterns, therefore, it is quite possible to detect a large variety of patterns in future.

PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAID) are well known to be associated with gastroduodenal ulcers. Also, small bowel ulceration sometimes develops. The authors reviewed their experiences to emphasize clinical importance of this disease entity. METHODS: A retrospective study was performed for patients who had undergone surgical intervention for lower gastrointestinal bleeding, small bowel perforation, or obstruction at Ewha Womans University Mok-Dong Hospital during a 5-year period. The cases related to acute trauma, postoperative obstruction, malignant ulceration, specific inflammatory bowel disease and other definite gastrointestinal lesions were excluded. The medical records were reviewed and the patients were interviewed. RESULTS: Out of total 110 cases, 4 patients had histories of NSAID use. They showed emergent presentations of acute abdomen, who were in debilitated or malnutrition states with underlying disease, without protective management for NSAID-use. They had all undergone surgical interventions because of small bowel ulcerations and its complications. CONCLUSION: NSAID induced small bowel ulcers should be a differential diagnosis of an acute abdomen or lower gastrointestinal bleeding of uncertain origin, especially for older age, and for patient with debilitating disease. Misuse or overuse of NSAID should be avoided to prevent ulcer complications, especially in high-risk patients.

PURPOSE: Catastrophic bleeding of the gastric varices has been considered a life threatening emergency. Sclerotherapy cannot easily control the bleeding, and there is a high risk of rebleeding despite successful intervention. Surgery is often necessary to save the life. The purpose of this study was to elucidate the role of surgery and analyze the factors determining operative mortality in gastric variceal bleeding. METHODS: A retrospective study was performed of 30 patients who underwent operation for gastric variceal bleeding with portal hypertension at Ewha Womans University Mok-Dong Hospital from Jul. 1994 to Feb. 2001. Among them, 23 patients received perigastric devascularization with fundectomy and the remainder received perigastric devascularization alone. RESULTS: There was one case of recurrent bleeding from esophageal varix at 8 months postoperative. This was controlled with sclerotherapy. The overall operative mortality rate was 30.0%. Preoperative hepatic functional reserve was a significant factor. The mortality rate was 0% (0/5) in Child-Pugh group A, 27.8% (5/18) in group B, and 57.1% (4/7) in group C (p<0.05). The preoperative success of intervention influenced postoperative outcomes. There was no mortality in the successfully controlled group (0/5). In the failure group, 5 of 7 patients expired (p<0.05). Preoperative transfusion amount was also a significant factor in determining survival. There was 15.8% (3/19) mortality rate in patients trans fused less than 10 units, and a 54.5% (6/11)rate in those receiving more than 10 units (p<0.05). CONCLUSION: This operative approach was effective for saving lives from an otherwise uniformly fatal disease. The rebleeding rate at the follow-up period was low. Proper selection of patients and an early surgical decision could lower the operative mortality.

PURPOSE: A choledochoscopy is useful for treating stone disease in the biliary tract. In the era of laparoscopic surgery, this method is expected to be used more widely. Its use during surgery may not only aid disease treatment, but may also help in making a differential diagnosis and a decision on the appropriate operative method. The aim of this study was to determine the role of intraoperative choledochoscopy in biliary surgery. METHODS: This study was a prospective analysis for 119 cases of biliary surgery where a choledochoscopy was used at the Ewha Womans University Mokdong Hospital from June, 1999 to February, 2001. An attempt was made to determine if the use of choledochoscopy altered the preoperative diagnosis, added another diagnosis and influenced the surgical treatment. In addition, the frequency of the remnant stones in biliary stone disease, and the complications related with this procedure were evaluated. RESULTS: The male to female ratio was 1:1.53, and the mean age was 61.1 (+/-14.53) years. A choledochoscopy was used in 82 cases (69%) in open surgery, and 37 cases (31%) in laparoscopic surgery. In 31 cases (26.1%), the diagnosis was changed by the choledochoscopic findings. In 9 cases (7.5%), new finding that was not recognized in the preoperative state was added with the use of choledochoscopy. The surgical method was influenced by the use of a choledochoscopy in 39 cases (32.8%). The remnant stones in patients with an intrahepatic duct stone and common bile duct stone were detected in 8 cases and 3 cases, respectively. The respective clearance rate of the stones were 79.5% (31/39) and 94.5% (52/55). There was no complications and side effects associated with the use of choledochoscopy. The mean time for diagnostic use was 14.6 (+/-10.0) minutes and for therapeutic use was 47 (+/-60.4) minutes. CONCLUSION: Intraoperative choledochoscopy provided useful information for a precise diagnosis and assisted in determining the appropriate treatment for biliary disease. Furthermore, it is very important for making a differential diagnosis in patients with an undetermined malignancy.

PURPOSE: To evaluate the safety of a laparoscopic cholecystectomy in acute, or complicated, cholecystitis in patients older than sixty. METHODS: A prospective study was performed, at the Ewha Womans University Mokdong Hospital, on a series of elderly patients (>60 years; n=137) who had undergone a laparoscopic cholecystectomy due to acute, or complicated, cholecystitis between March 1997 and December 2001. We divided the patients into 3 groups; ASA 1 (n=33, 24.1%), ASA 2 (n=79, 57.7%) and ASA 3 (n=25, 18.3%), according to their ASA (American Society of Anesthesiologist) classification. No patient was categorized as either ASA 4, 5 or 6. RESULTS: The mean age of the ASA 3 patients was 71.9+/-6.9 years, which was older than the 65.7+/-6.0 years of the ASA 1 patients (P<0.05). The preoperative hospital stay for the ASA 3 patients was 8.8+/-5.6 days, compared to 5.6+/-3.7 days for the ASA 1 patients (P<0.05). The incidences of complicated cholecystitis were lower in the ASA 1 (n=8, 24.2%) than in both the ASA 2 (n=40, 50.6%) and 3 patients (n=12, 66.7%) (P<0.05). The mean operating times for the ASA 2 and 3 patients were longer, at 111.0+/-58.2 and 114.0+/-62.7 minutes, retrospectively, than the 85.0+/-33.1 minutes for the ASA 1 patients (P<0.05). Drain insertions were more frequently performed in the ASA 2 (n=33, 44.4%) and 3 (n=15, 60.0%) than in the ASA 1 patients (n=10, 30.3%) (P<0.05). Postoperative morbidity was more frequent in the ASA 3 (n=5, 20.0%) than ASA 1 (n=3, 9.1%) patients. However, in terms of the postoperative recovery parameters (time to diet, hospital stay), there were no difference between the three groups (P>0.05). One death, due to acute myocardial infarction, occurred in one of the ASA 3 patients. CONCLUSION: A laparoscopic cholecystectomy in acute, or complicated, cholecystitis could be an option in elderly-high risk patients.

PURPOSE: This study aimed to investigate the outcomes of modular neck-utilization in primary total hip arthroplasty (THA). MATERIALS AND METHODS: Thirty patients (34 hips) who had modular stem THA between April 2011 and January 2013 were evaluated. There were 19 men and 11 women with a mean age of 61.2 years at the time of surgery. There were 20 cases of osteonecrosis of femoral head, 7 cases of osteoarthritis, 6 cases of femur neck fracture, and 1 case of rheumatoid arthritis. No patients presented with anatomical deformity of hip. Patients were operated on using a modified Watson-Jones anterolateral approach. All patients underwent clinical and radiological follow-up at 6 weeks, 3, 6, and 12 months, and every year postoperatively. The mean duration of follow-up was 48.2 months (range, 39 to 59 months). RESULTS: The average Harris hip score improved from 63.7 to 88.1 at the final follow-up. Radiographically, mean acetabular cup inclination was 45.3°(range, 36°-61°) and anteversion was 21.7°(range, 11°-29°). All were neutral-positioned stems except 5 which were varus-positioned stems. In only 3 cases (8.8%), varus or valgus necks were required. A case of linear femoral fracture occurred intraoperatively and 1 case of dislocation occurred at postoperative 2 weeks. No complications at modular junction were occurred. CONCLUSION: Our study shows that the use of modular necks had favorable clinical and radiographic results. This suggests that the use of modular neck in primary THA without anatomical deformity is safe at a follow-up of 39 months.

PURPOSE: The purpose of this study was to evaluate the feasibility and potential benefits of Hand-Assisted Laparoscopic Surgery (HALS) with the HandPort system. The surgeon inserts the nondominant hand into the abdomen while the pneumoperitoneum is maintained. The hand assists laparoscopic instruments and is helpful in complex laparoscopic surgery. This approach provides an excellent means to explore, to retract safely, and to apply immediate hemostasis when needed. METHODS: A prospective study was performed in patients who had undergone surgical intervention with the HandPort system at Ewha Womans University Mok-Dong Hospital. The surgeon was free to test the device in any situation where they expected a potential advantage over conventional laparoscopy. The surgeon inserted the nondominant hand into the abdomen while the pneumoperitoneum was generally maintained at 13 mmHg. RESULTS: Thirteen patients were entered in the study. Operations included radical gastrectomy in 8 cases, subtotal gastrectomy in 1 case, hemicolecotmy in 2, distal pancreatectomy with splenectomy in 1, nephrectomy with splenectomy in 1. The mean incision size for the HandPort device was 7.5 cm for the nondominant hand. None of the patients required conversion to open surgery as a result of an unmanageable air leak. There were no postoperative problems and no cases of mortality. CONCLUSION: HALS with the HandPort system is helpful in complex laparoscopic surgery and appeared to be useful in minimally invasive procedures considered too complex for,a laparoscopic approach.
