Purpose: Squamous cell carcinoma of the scalp sometimes exhibits unusually aggressive behavior. We report a case of extradordinarily aggressive squamous cell carcinoma of the scalp with invasion into the skull and dura mater. Method: The patient is a 38-year-old man with two cystic masses on the occipital area. He was diagnosed as squamous cell carcinoma in that region and have undergone surgical resections including cortical osteotomy of the skull, several years ago. On this occasion, 3-dimensional computed tomographic imaging revealed an erosive lesion on the occipital bone and magnetic resonance imaging showed two cystic masses invasion into the skull and dura mater. Results: He has undergone wide resection of the masses and cranioplasty with dural repair. Histopathologic examination indicated squamous cell carcinoma with moderate differentiation of the masses, bone marrow and dura mater. Conclusion: Squamous cell carcinoma on the scalp can readily penetrate the full thickness of the cranium and invade the dura mater, sagittal sinus and brain. We suggest wide resection of the scalp and split thickness skin graft with sentinel lymph node biopsy, following by postoperative radiation therapy.

Purpose: The advantages of totally laparoscopic surgery in early gastric cancer (EGC) are unproven, and some concerns remain regarding the oncologic safety and technical difficulty. This study aimed to evaluate the technical feasibility and clinical benefits of totally laparoscopic distal gastrectomy (TLDG) for the treatment of gastric cancer compared with laparoscopy-assisted distal gastrectomy (LADG). Materials and Methods: A retrospective review of 211 patients who underwent either TLDG (n=134; 63.5%) or LADG (n=77; 36.5%) for EGC between April 2005 and October 2013 was performed. Clinicopathologic features and surgical outcomes were analyzed and compared between the groups. Results: The operative time in the TLDG group was significantly shorter than that in the LADG group (193 [range, 160~230] vs. 215 minutes [range, 170~255]) (P=0.021). The amount of blood loss during TLDG was estimated at 200 ml (range, 100~350 ml), which was significantly less than that during LADG, which was estimated at 400 ml (range, 400~700 ml) (P<0.001). The hospital stay in the TLDG group was shorter than that in the LADG group (7 vs. 8 days, P<0.001). One patient from each group underwent laparotomic conversion. Two patients in the TLDG group required reoperation: one for hemostasis after intraabdominal bleeding and 1 for repair of wound dehiscence at the umbilical port site. Conclusions: TLDG for distal EGC is a technically feasible and safe procedure when performed by a surgeon with sufficient experience in laparoscopic gastrectomy and might provide the benefits of reduced operating time and intraoperative blood lossand shorter convalescence compared with LADG.

Background: Surgical repair of a partial anomalous pulmonary venous connection (PAPVC) to the superior vena cava (SVC) may be complicated by sinus node dysfunction or SVC obstruction. We modified the Warden procedure by using a right atrial auricular flap to decrease the occurrence of these complications. Methods: Between February 2005 and July 2012, 10 consecutive patients underwent a modified Warden procedure to correct PAPVC. The median patient age was 5.7 years. Eight patients (80%) had an atrial septal defect. To surgically correct the PAPVC, we made a U-shaped incision on the right atrial appendage and sutured the flap to the posterior wall of the SVC. The anterior wall was reconstructed with various patch materials. Results: No early or late deaths occurred, nor did any patient require early or late reoperation for SVC or pulmonary venous obstruction. No new arrhythmias appeared during follow-up, which was complete in all patients (mean, 29.5 months). Conclusion: Our modification of the Warden procedure seems to be effective and safe. This technique may lower the risk of SVC obstruction, pulmonary venous obstruction, and sinus dysfunction.

Generally, the totally paralyzed face can never be made normal by any of the current methods of reconstruction. Careful selection of patients based on sound judgment of what can and cannot be achieved by the proposed surgical technique is paramount to a successful operation and a satisfied patient. The results are related to time of delayed between injury and repair ; the shorter the delay the better are the results. The objectives in correcting facial paralysis are to achieve normal appearance at rest ; symmetry with voluntary motion ; control of the ocular, oral, and nasal sphincter ; symmetry with involuntary emotion and controlled balance when expressing when expressing emotion ; and no significant functional deficit secondary to the reconstructive surgery. It must be employed a number of concepts, for treatment of the paralyzed face by surgeon, depending on the cause, time interval, and wound characteristics, as well as the availability of and necessity for neuromuscular substitution. Nerve grafts, crossovers, muscle transfers, free muscle and nerve-muscle grafts, micronuerovascular muscle transfers, and regional muscle transposition are the principal methods being developed. We applied the temporal musle transposition for reanimation of unilatrally paralyzed faces for long times on two patients. The results of muscle transposition can be enhanced by the patient's learning to activate the transposed muscle by voluntary effort, and are best in patients who are motivated to learn the necessary motor-sensory coordination techniques.

Objective: To explore the value of porous titanium alloy plates for chest wall reconstruction after resection of chest wall tumors. Materials and Methods: A total of 8 patients with chest wall tumors admitted in our hospital from Jan. 2006 to Jan. 2009 were selected and underwent tumor resection, then chest wall repair and reconstruction with porous titanium alloy plates for massive chest wall defects. Results: All patients completed surgery successfully with tumor resection-induced chest wall defects being $6.5{\times}7cm{\sim}12{\times}15.5$ cm in size. Two weeks after chest wall reconstruction, only 1 patient had subcutaneous fluidify which healed itself after pressure bandaging following fluid drainage. Postoperative pathological reports showed 2 patients with costicartilage tumors, 1 with squamous cell carcinoma of lung, 1 with lung adeno-carcinoma, 1 with malignant lymphoma of chest wall, 2 with chest wall metastasis of breast cancers and 1 with chest wall neurofibrosarcoma. All patients had more than 2~5 years of follow-up, during which time 1 patient with breast cancer had surgical treatment due to local recurrence after 7 months and none had chest wall reconstruction associated complications. The mean survival time of patients with malignant tumors was ($37.3{\pm}5.67$) months. Conclusions: Porous titanium alloy plates are safe and effective in the chest wall reconstruction after resection of chest tumors.

Objectives: To evaluate the effectiveness of regenerative tissue matrix (Alloderm) as an oral layer for difficult anterior palatal fistula closure. Materials and Methods: The authors have tested the feasibility of a novel surgical technique of adding a regenerative tissue matrix (Alloderm) as an oral layer for closure of recalcitrant large anterior palatal fistulae and report the outcome of the first 12 patients in this pilot study. Patients with recurrent large fistula who otherwise would require either a local pedicled flap, free flap, or an obturator were treated with this technique and followed up for at least 6 months to monitor the progress of healing. Results: Of the 12 patients, 8 patients (66.7%) had complete closure of the fistula, and 2 patients (16.7%) showed reduction in size of the fistula to the extent that symptoms were eliminated, for an overall success rate of 83.3% (10/12 patients). Premature graft loss and recurrence of the fistula were noted in 2 patients (16.7%). Conclusion: Alloderm provided an adequate barrier allowing healing to occur unimpeded and allowed closure of the palatal fistula. In our experience, this new technique using regenerative tissue matrix as an adjunct to the oral layer in large anterior palatal fistula has an advantage compared to other more invasive complex procedures and has been shown to provide satisfactory results.

While nontuberculous mycobacterium (NTM) infections are recently on the rise, arthritis caused by NTM is hardly reported in Korea. NTM arthritis has no distinctive clinical characteristics from chronic arthritis. Tuberculosis of the joint specifically produces similar clinical and pathologic presentations to NTM arthritis, so it is not easy to distinguish between them. We report a case of Mycobacterium intracellulare in an arthritis patient after trauma and surgical repair of the injury. At the beginning, the patient was diagnosed as tuberculous tenosynovitis through pathology without microbiologic evidence. The final diagnosis was made after subsequent recurrences for several years. The misdiagnosis and delayed diagnosis led to irreversible joint destruction and functional impairment. NTM infection must be included in the differential diagnosis of chronic arthritis at the outset.

The present study reports 41 cases of congenital and acquired heart diseases, who received open heart surgery under extracorporeal circulation [ECC] by Sarns Heart-Lung-Machine [HLM] at the Department of Thoracic and Cardiovascular Surgery, Hanyang University Hospital during the` period between July 1975 and February 1979. The priming of pump oxygenator was carried out by the hemodilution method using Hartman`s solution, whole blood, and fresh human plasma. The rate of hemodilution was in the average of 50.8 ml/kg. ECC was performed at the average perfusion flow rate of 85.0 ml/kg/min [2.43 L./ kg/2] and at moderate hypothermia. In the total cardiopulmonary bypass, arterial pressure ranged between 55 mmHg and 90 mmHg, but generally maintaining over 70 mmHg. Patient age ranged between 2 and 54 year old, in congenital heart diseases, between 2 and 28, in acquired heart diseases, between 17 and 54 Sex ratio of male to female was 20:21. The cases include a case of pulmonary valvular stenosis, 4 cases of atrial septal defect, 9 cases of ventricular septal defect, 9 cases of tetralogy of Fallot, 5 cases of pentalogy of Fallot, 3 cases of atypical multiple anomalies 7 cases of mitral stenosis or insufficiency, a case of myxoma in left atrium, and a case of ruptured aneurysm of Valsalva`s sinus. The surgical managements were 16 valvulotomy for pulmonary valvular stenosis, 2 Teflon patch graft closure and 5 simple suture closure of atrial septal defect, 16 Teflon patch graft closure and 5 simple suture closure of ventricular septal defect, 12 pericardial patch graft for infundibular stenosis of right ventricle, one anastomosis between left superior vena cava and right atrium, 2 open mitral commissurotomy, 5 mitral valve replacement using Starr-Edward`s ball valve, porcine xenograft by Hancock, by Carpentier-Edward, or Angell-Shiley, one removal of left atrial myxoma, and a repair of ruptured aneurysm of Valsalva`s sinus. Four [9.7%] out 41 cases expired postoperatively and the rest of 37 cases survived with satisfactory results. The causes of death were one coronary embolism in tetralogy of Fallot, 2 postoperative lower cardiac output in atypical multiple anomalies, and one right heart failure in large: ventricular septal defect with pulmonary hypertension.

Corrected transposition of the great arteries [C-TGA] is one of the rare congenital heart disease in which there is both a discordant atrioventricular relationship and transposition of the great vessels. With this arrangement, systemic venous blood passes through the right atrium into the morphologic left ventricle and out the pulmonary artery. Pulmonary venous blood returns to the left atrium, flows into the morphologic right ventricle and out the aorta. Thus, in the rare case when no additional cardiac anomaly is present, a hemodynamically normal heart exists. But more often they are symptomatic as a result of one or several of the commonly associated defects. This paper describes 13 patients who underwent repair of one or more cardiac anomalies associated with corrected transposition at SN UH, from June 1976 through June 1984. 1.8 were males and 5 females, with ages ranging from 3 years to 27 years. 2. Segmental anatomy was {S,L,L} in 12, or {I,D,D} in 1. 3.Associated anomalies were ventricular septal defect in 10, pulmonary outflow tract obstruction in 6, tricuspid insufficiency in. 4, atrial septal defect in 3, subaortic stenosis in 1, mitral insufficiency in 1, and patent ductus arteriosus in 1. 4.None had complete heart block preoperatively, and 3 developed complete heart block intraoperatively. But one of them recovered sinus rhythm on the postoperative 7th day spontaneously. 5.There were 3 cases of hospital morality. But there was no morality since Dec. 1980. 6.Patients with single ventricle, hypoplastic ventricle or those who had palliative surgery alone are not included in this review.
