Purpose: Minimally invasive gastrectomy (MIG), including laparoscopic distal subtotal gastrectomy (LDG) and robotic distal subtotal gastrectomy (RDG), is performed for gastric cancer, and requires a learning period. However, there are few reports regarding MIG by a beginner surgeon trained in MIG for gastric cancer during surgical residency and fellowship. The aim of this study was to report our initial experience with MIG, LDG, and RDG by a trained beginner surgeon. Materials and Methods: Between January 2014 and February 2015, a total of 36 patients (20 LDGs and 16 RDGs) underwent MIG by a beginner surgeon during the learning period, and 13 underwent open distal subtotal gastrectomy (ODG) by an experienced surgeon in Bundang CHA Medical Center. Demographic characteristics, operative findings, and short-term outcomes were evaluated for the groups. Results: MIG was safely performed without open conversion in all patients and there was no mortality in either group. There was no significant difference between the groups in demographic factors except for body mass index. There were significant differences in extent of lymph node dissection (LND) (D2 LND: ODG 8.3% vs. MIG 55.6%, P=0.004) and mean operative time (ODG 178.8 minutes vs. MIG 254.7 minutes, P<0.001). The serial changes in postoperative hemoglobin level (P=0.464) and white blood cell count (P=0.644) did not show significant differences between the groups. There were no significant differences in morbidity. Conclusions: This study showed that the operative and short-term outcomes of MIG for gastric cancer by a trained beginner surgeon were comparable with those of ODG performed by an experienced surgeon.
We have performed left lung transplantation followed by ligation of right pulmonary artery in 14 dogs at the Chest Disease Research Institute, Yonsei University College of Medicine from May 1992 to February 1994. Excised left lung was perfused with 1500cc of 4$^{\circ}$C cold Euro-Collin`s[E-C] solution at a pressure of 30cmH2O through main pulmonary artery and preserved in 4$^{\circ}$C cold E-C solution for one hour. Left lung transplantation were proceeded in order of left atrium, left main bronchus, left pulmonary artery and right pulmonary artery ligation as usual method. The femoral artery and pulmonary artery pressures were monitored for more than 5 hours after the transplantations in 14 dogs. Six recipient dogs had elevated mean pulmonary artery pressure to greater than 30mmHg after the left lung transplantation and ligation of right pulmonary artery. The cause of elevated mean pulmonary artery pressure was due to inadequate preservation resulting in ischemic damage to donor lungs in 3 cases, and inadequate surgical techniques in 3 cases. Two recipient dogs without surgical complications died immediate post-operatively due to hemorrhagic shock. The bleeding focuses were LA anastomotic site in one case and femoral artery puncture site in another case. The remaining 6 recipient dogs showed mean pulmonary arterial pressure less than 30mmHg. However, one dog had spontaneous pneumothorax in post-operative 4 days, and another dog had rejection phenomenon in post-operative 5 days which was confirmed by pathologic findings of extracted transplanted lung. One dog succumbed of severe hemoptysis which was due to lung abscess with pin point stenosis of bronchial anastomosis in post-operative 38 days. In conclusion, elevated mean pulmonary arterial pressure greater than 30mmHg in immediate postoperative period can be due to inadequate preservation of extracted lung or poor surgical techniques. And the two dogs succumbed of hemorrhagic shock even though the mean pulmonary arterial pressure was less than 30mmHg. It is thought that careful preservation of the extracted donor lung in 4oC E-C solution and complete surgical techniques are the most important factors early and late complications.

Objective: To compare the analgesic effects and adverse drug reactions (ADRs) of fentanyl intravenous patient-controlled analgesia (ivPCA) with nefopam, a centrally acting analgesic agent with demonstrated opioid sparing activity, as compared to ketorolac in a tertiary teaching hospital. Methods: A retrospective evaluation of electronic medical records was conducted on patient records including either nefopam or ketorolac with opioid ivPCA for post-operative pain management in general surgery department from January to December 2014. The status of pain control and ADRs were collected. Results: Out of 6,330 general surgery cases, nefopam was given in 153 prescriptions (6.9%) and ketorolac in 81 prescriptions (3.6%). The level of pain control was not different between two groups (70.9% vs. 75.3%; p = 0.51), but ADRs were more frequently reported in nefopam group (9.8% vs. 2.5%; p < 0.05). New ADRs of hot flushes (n = 1) and paresthesia in hands (n = 1) were reported in nefopam group and they were unlisted in the approved package insert. No serious ADRs were reported in both groups. Conclusion: Our findings presented that nefopam showed a similar analgesic effect and higher ADR rates compared to ketorolac as an adjuvant to fentanyl iv PCA for post-operative pain management in general surgery patients in South Korea.
Ascariasis symptoms penetrated into biliary tract are reported to be found much more in Korea than in foreign countries. And the present writer believes there are also many cases of biliary tract symptoms that are actually experienced but that are not reported. As a result of experiencing and nursing twenty cases of ascariasis symptoms of biliary tract, the present writer has got several conclusions, and reports them together with reference to sundry records. (1) The penetrating rate of ascariasis in male versus female was 1 to 1.5. Consequently the rate of female was higher than that of male. The highest age of the case was 67, the lowest 19, and the average age was 45.2. (2) As to symptoms, right upper quadrant abdomen pain and fat diet intolerance were the largest in number. By laboratory findings there were depressive pain on right upper quadrant abdomen in all the cases. (3) As to the location of ascariasis, choledochus occupied the largest part, and the longer illness history was, the more cases coexisting with calculus were found. (4) As to operative method, cholecystectomy and choledochotomy weres the largest in number, and choledochotomy T-tube was inserted in all cases. As to complication after operation, there were operative wound infection, excoriation through bile juice issue, etc. There were three cases of re-penetration of ascariasis and only one case of reoperation.
Neuroblastoma is a solid tumor derived from neural crest cells of the sympathetic nervous system. It is the most common extracranial solid tumor in children. Although it has the highest rate of spontaneous regression, it has a bad prognosis. Recent reports indicate a much improved outcomes utilizing the multitreatment approaches and early diagnosis as a result of patient screening. We have studied 42 patients managed in the last decade at the Severance and Yongdong Severance Hospitals. The patients were followed until January 1998 and analyzed in terms of age, sex, admission period, stage, diagnostic studies, clinical symptoms, physical findings, operative time, treatment modalities, and survival rate. Twenty eight patients underwent operative procedures, 16 patients had postoperative chemotherapy, and 19 patients had preoperative chemotherapy. Sexual difference was 1.33:1 in favor of males, and 43 % of patients were under one year of age. The patients were initially diagnosed as a result of symptoms and signs. An abdominal mass was the most common clinical finding. Eighty six percent of the patients were in advanced stages (>Stage III of INSS). The 2 year survival rate was 59.2 % and the 5 year survival rate was 29.6 %.
Pulmonary artery aneurysm is Behcet`s disease is rare and can be fatal due to rupture. We experienced a case of pulmonary artery aneurysm in Behcet`s disease. The patient was 21 year old woman who was adimitted with three month history of dyspnea, fever and cough. On examination, she had aphthous ulcer in the mouth and erythema nodosum on the left popletial fossa and forearm, but didn`t have any lesion at eyes and genitalia. The latex fixation test for rheumatoid factor, VDRL test for syphillis, antinuclear antibody and LE cell test were all negatives. The third and fourth components of complement in the serum, serum immunoglobulin concentrations[IgG, IgM, IgA] were within normal range. The chest radiography revealed a 5x6cm sized radiopaque mass density in the left hilar region. Two months later, the mass was enlarged to 6x7cm. The IV-DSA showed a single aneurysm at the proximal part of left lower lobe artery with lingular segment artery and no distal perfusion by thombotic obstruction. The steroid therapy was done for a month, but symptoms not improved. We performed resection of lingular segment and lower lobe including the aneurysm. The microscopic findings of the operative specimen were intimal hyperplasia and fragmentation of the internal elastic fibers. She was improved without remarkable event, except infection of the operative wound.
Forty eight patients diagnosed as atrial septal defect, had been operated from April 1986 to December 1990 at the Department of Thoracic and Cardiovascular Surgery, Inha University Hospital, were analysed retrospectively. Of the 48 patients, 12 patients, were male and 36 patients were female, Their ranged from 8 months to 51 years old, and the mean was 18.0 years old. The proceeding two symptoms were exertional dyspnea and frequent upper respiratory infection. But 10 patients [20.8%] were asymptomatic. Electrocardiographic findings were regular sinus rhythm in 100.0%, RVH in 29.2%, incomplete RBBB in 27.1%, and first degree AV block in 2.1%. Hemodynamic studies were performed in 38 of 48 patients. Significant pulmonary hypertension[over 50mmHg in systolic pulmonary arterial pressure], which is the most serious risk factor, was developed in 4 patients[8.3%]. There was statistical significance between size of defect[cm2/BSA-M2] and systolic pulmonary arterial pressure[sPAP] retrospectively[p=0.036]. We could not find the correlationship between age and Qs % size. Anatomically, secundum type constituted 97.9%, in which 43 patients were PFO type[91.6%] and 3 patients were IVC type[6.3%]. 38 of 48 ASD patients were repaired with patch closure[72.9%] and remains were repaired with direct closure[27.1%]. The operative result was excellent except two cases of transient postoperative arrhythmia. There was no operative mortality.
Surgical treatment of partial endocardial cushion defect was accomplished in Feb. 1984 in this department. The 5 year old male patient had history of frequent upper respiratory tract infection and since his age of 3 years dyspnea on exertion and palpitation were noted but there were no cyanosis and clubbing. A thrill was palpable on the apex and grade IV/IV harsh systolic ejection murmur and diastolic murmur was audible on it. Liver was palpable about 3 finger breadths and no ascites. Chest X-ray revealed increased pulmonary vascularity, moderate cardiomegaly [C-T ratio; 0.69], and enlarged left atrium. EKG showed first degree heart block, RVH, LVH, and LAD. Echocardiogram showed paradoxical ventricular septal movement and abnormal diastolic movement of the anterior leaflet of mitral valve. Right heart catheterization resulted left to right shunt [Qp:Qs:2.1:1 ] and moderate pulmonary hypertension [60/40 mmHg]. Left ventriculogram showed mitral regurgitation [Grade III/IV] and filling of left atrium and right atrium nearly same time. Operative findings were: 1.Primum type atrial septal defect [3x2 cm] 2.Cleft on the anterior leaflet of mitral valve. 3.No interventricular communication and cleft of tricuspid valve leaflet. The mitral cleft was repaired with 4 interrupted sutures. The primum type atrial septal defect was closed with Dacron patch intermittently at endocardial cushion and continuously remainder. The post operative course was uneventful and discharged on 22nd postoperative day in good general conditions.
The purpose of this paper is to present author's experience with 6 cases of ruptured aneurysm of sinus of Valsalva which were treated surgically during last 10 years. Among the 6 cases, 5 were male and one was female. All of them originated from the right coronary sinus and 5 cases were ruptured into the RV while remained one into RA. The diagnosis was obtained in 4 cases by cineangiocardiogram. Clinically, we had difficulties in differential diagnosis with combined cases of VSD with A.I. and had special experience in its differentiation during cardiac catheterization. By simultaneous trans-venous and trans-arterial catheterization, identified two catheter tips in the RV, and pull back tracing obtained aortic pressure directly from RV, and RA from RV pressure which were benefit in confirm ruptured aneurysm of the aortic sinus. Surgical correction was performed by means of direct suture closure or combined Teflon pledget Of patch enforcement graft after aneurysm resection by trans-RA or trans-RV approach. All patients had no history of bacterial endocarditis, syphilis, or tuberculosis and operative findings revealed intact coronary sinus except involved one moreover 3 cases combined with high VSD which uggested congenital in origin although pathologic reports revealed only fibrosis. Post-operative course were uneventful in all cases but one who had bleeding and 2 months to 9 years follow up results were good and spend their usual life in all cases.
A fibroma arising in the right ventricle outflow tract of a 14 month-old infant was successfully removed. The patient was first seen because of shortness of breath and tachycardia. Pertinent clinical and laboratory findings included a grade II/VI systolic murmur, blood pressure of 120/60 mmHg, slight cardiomegaly on chest X-ray, a mass obstructing the outflow tract of the right ventricle on echocardiography and magnetic resonance imaging. On october 30,1992, under cardiopulmonary bypass, a 4cm x 3cm x 3cm tumor was resected from the right ventricular outflow tract, together with a portion of the ventricular wall. Histologically, it was diagnosis as a fibroma. The patient was sent home on the 6th postoperative day following an uneventful recovery form the operation. Although cardiac fibroma is the second most common cardiac tumor in infancy and childhood, it is usually found in the left ventricle and one arising in the right ventricle is considered rare. Although it is a benign tumor, it could produce a severe cardiac dysfunction and even sudden death, depending on its size and location. With the advance in diagnostic techniques and operative management, there is a renewed interest in the early detection and operative removal of these tumors. The case herein presented is the first such case successfully managed and reported in the Korean literature.
