배경: 최근에 시작된 소절개선을 이용한 심장수은술 환자에게 미용상 효과가 좋으며, 통증이 적으며 빠른 회복을 가져온다. 본 교실에서는 그간 실시한 소절개심장수술의 현황을 임상고찰하였다. 대상 및 방법: 1997년 2월 흉골좌연종절개선으로 관상동맥우회술을 실시한 이후 1998년 11월까지 총 31례의 소절개술을 이용한 심장수술을 실시하였다. 남녀 비는 17:14였으며, 1세에서 75세까지의 연령분포를 보였다. 흉골좌연종절개술을 실시한 예는 9례로 관상동맥 질환으로 인공심폐기의 사용없이 박동상태에서 내유동맥으로 좌전행지관상동맥에 우회술을 실시하였는데, 그 중 1례는 내유동맥의 비꼬임으로 술 후 1주일 째 재수술한 경우였다. 흉골우연종절개는 1례로 승모판교련절개술 후 재발된 협착증에 대해 승모판치환술을 실시한 경우였다. 소흉골절개선으로 수술한 예는 21례로, 승모판치환 및 삼첨판성형술이 6례, 승모판치환술 5례, 중복판치환술 2례, 대동맥판치환술 1례, 좌심방점액종 1례, 심방중격결손증 2례, 심실중격결손증 2례, 우심실 자창 1례였다. 처음 5례는 T형의 흉골소절개를 실시하였으나 경험이 쌓이면서 대동맥기저부의 노출이 좋고 흉골 봉합시 안정감이 높은 화살모양의 흉골소절개를 실시하였다. 결과: 수술시간, 인공심폐 구동시간, 대동맥차단시간, 인공호흡기 사용기간, 수술 1일까지의 흉관배액양, 흉관 거치기간, 집중치료실 입원기간 등은 기존의 정중흉골절개선 예들에 비하여 큰 차이가 없었다. 수술 후 사망 예는 2례였으며 1례는 흉골소절개선으로 승모판치환 수술 1일에 대동맥 삽관부위의 파열로 출혈 사망하였고, 다른 1례는 흉골좌연종절개선으로 관상동맥우회술 후 2일에 부정맥으로 사망하였다. 사망의 원인과 수술절개선의 선택과는 직접적인 관련이 없었다. 합병증은 뇌색전증 1례, 창상의 혈종 1 례가 있었다. 결론: 소절개선으로도 정중흉골절개선과 마찬가지로 심장 수술을 효과적으로 실시할 수 있을 것으로 생각된다.

Background: The chin shape and position is important in determining the general shape of the face, and augmentation genioplasty is performed alone or in combination with other aesthetic procedures. However, augmentation genioplasty using osteotomy is an invasive and complex procedure with the potential to damage mentalis muscle and mental nerve, to affect chin growth, and prolonged recovery. Our aim was to present our experience with a modified augmentation genioplasty procedure for hypoplastic chins using a Gore-Tex implant. Methods: Two vertical slit incisions were made at the canine level to create a supra-periosteal pocket between the incisions, preserving the periosteum and mentalis muscle. Minimal sub-periosteal dissection was performed lateral to the incisions along the mandibular border. The both wings of implant were inserted under the periosteum to achieve a stable dual plane implantation. Results: In total, 47 patients underwent dual plane chin augmentation using a Gore- Tex implant between January 2008 and May 2013. The mean age at operation was 25.77 years (range, 15-55 years). There were 3 cases of infection; one patient was treated with antibiotics, the others underwent implant removal. Additionally, two patients complained of postoperative parasthesia that spontaneously improved without any additional treatment. Most patients were satisfied with the postoperative outcomes, and no chin growth problems were observed among the younger patients. Conclusion: Dual plane Gore-Tex chin augmentation is a minimally-invasive operation that is simple and safe. All implants yielded satisfactory results with no significant complications such as mental nerve injury, lower lip incompetence, or chin growth limitation.

Introduction : Although bilateral exploration has been thought to be the standard therapeutic modality for primary hyperparathyroidism(pHPT) due to the admirable cure rate, questions have remained as to whether bilateral neck exploration for all patients with pHPT is needed because 80-85% of patients with pHPT have a single parathyroid adenoma. If the diseased parathyroid can be determined preoperatively, a directed and minimal operation is appropriate using the recent innovations of preoperative diagnosis and operation techniques for parathyroid diseases, the radio-guided parathyroid surgery(RGPS) is one of the standards. In especial, RGPS has been reported beneficial in special circumstances, such as in recurrent disease, ectopic parathyroid, and in mediastinal parathyroid. It can be also useful for the parathyroid disease in previously explored or irradiated neck. Material and Methods : We experienced 2 cases of pHPT successfully treated by RGPS in who previously underwent extensive neck dissection and concomitant external or internal radiotherapy. We adopted and modified the technique described by Dr. James Norman at the University of South Florida-the minimally invasive parathyroidectomy using intraoperative nuclear mapping with 99mTc-sestamibi scanning and radioactivity detection probe. Results : We acquired the successful results for these patients. Conclusion : RGPS is thought to be the alternative technique for the patients with prior central neck exploration and irradiation.

관상동맥우회술은 인공심폐기 및 심근보호의 안정성으로 인공심폐기 사용하에 시행하는 것이 보편화된 방법이다. 그러나 좌전하행지 및 우관상동맥에 병소가 위치하는 경우는 인공심폐기의 사용 없이 심장이 박동하는 상태에서 관상동맥우회술을 시행하는 방법도 일부에서는 시행되어 왔으며 최근에는 최소한의 절개하에서 관상동맥우회술을 시행하는 방법도 대두되었다. 본 병원에서는 1996년 3월부터 8월까지 시행한 35례의 관상동맥우회술중 6례에서 인공심폐기를 사용하지 않고 관상동맥우회술을 시행하였다. 환자는 남자 4례와 여자 2례였으며 나이는 55세에서 76세로 평균 64세였다. 수술전 관상동맥의 병소는 6례 모두 좌전하행지에 90%이상의 협착을 보였으며 1례는 대각지가 50%, 또 다른 1례에서는 좌주관상동맥이 50%정도의 협착을 동시에 보였다. 수술에 필요한 개흉방법은 통상적인 정중흉골절개가 1례, 부분흉골절개술을 시행한 경우가 2례, 좌측전흉부를 개흉한 경우가 3례였다. 관상동맥우회술은 5례에서 좌측내흉동맥을 좌전하행지에 문합하였으며, 1례에서는 좌측내흉동맥에 요골동맥편을 단단문합한후 좌전하행지에 문합하였다. 또한 1례는 복재정맥을 이용하여 대각지에도 동시에 우회술을 시행하였다. 수술후 기관발관시간은 4시간에서 14시간으로 평균 9시간이었다. 수술에 사용한 혈액의 양은 평균 800 ml였으며 2례에서는 전혀 혈액을 사용하지 않았다. 이들중 5례에서 수술후 추적관상동맥조영술을 술후 7일에서 10일사이에 시행하여 100%의 개통율을 보였다. 결론적으로 좌전하행지나 우관상동맥에 협착이 있는 경우나 상기병소에 경피적풍선확장술이 실패한 경우에 인공심폐기를 사용하지 않고 최소한의 개흉하에 관상동맥우회술을 시행하는 것도 하나의 방법이라 사료되며 앞으로 기술적 발전과 더불어 적응대상군이 증가할 것으로 판단된다.32, 88.67$\pm$10.22 mmHg로 감소하였고 폐동맥압의 평균은 수술전에 11.4$\pm$5.68 mmHg에서 25.94$\pm$11.53, 29.67$\pm$9.31 mmHg로 증가 하였으나 모두 통계적 의의는 없었다(p>0.05). 양측 폐이식수술에서인 폐동정맥문합부위의 파열, 협착, 뒤틀림 등의 수술수기상의 문제점을 예방하면서 우측폐를 먼저 이식하면서, 폐수술시야를 충분히 확보하고, 재관류손상을 방지하는 경우 cystic fibrosis, pulmonary hypertention, emphysema와 같은 심한 호흡부전증 환자의 치료방법으로 적합하리라 사료된다.에서 선택수술 (elective coronary artery bypass graft)에 비하여 특별한 위험 요소의 증가 관상 동맥 우회술을 적용하여 좋은 결과를 얻을 수 있었으며 이들에 대한 장기 추적이 릴요할 된다.착군에 비하여 의미있게 작았는데 이는 아마도수술 당시 협 착 부위의 완전제거가 이루어지지 않은 것이 원인이라고 사료되었다. 본 분석에서는 어린 연령(3개월 이하), 3개월이하에 시행한 쇄골하동맥편 교약성형술이 의미있는 재협착의 위험요소로 밝혀졌다. 결론 적으로 저자등은 본연구를 통하여 대동맥협부지수, 횡대동맥 지수 등이 개개 대동맥교약 환아의 해부학 적, 임상적 특징을 파악하는데 도움이 되는 도구라는 사실을 발견하였고 아울러 교약의 해부학적 특성, 동반 심기 형, 연령, 수술방법 등이 수술사망 및 재협착에 영향한다는 사실을 입증하였다.t was resulted from increase of weight of single cocoon.

Purpose: Proximal gastrectomy (PG) is a function-preserving surgery in cases of proximally located early-stage gastric cancer. Because gastroesophageal reflux is a major pitfall of this operation, we devised a modified esophagogastrostomy (EG) anastomosis to fix the distal part of the posterior esophageal wall to the proximal part of the anterior stomach wall to produce an anti-reflux mechanism; we named this the SPADE operation. This study aimed to show demonstrate the clinical outcomes of the SPADE operation and compare them to those of previous PG cases. Materials and Methods: Case details of 56 patients who underwent PG between January 2012 and March 2018 were retrospectively reviewed: 30 underwent conventional esophagogastrostomy (CEG) anastomosis using a circular stapler, while 26 underwent the SPADE operation. Early postoperative clinical outcome-related reflux symptoms, endoscopic findings, and postoperative complications were compared in this case-control study. Results: Follow-up endoscopy showed more frequent reflux esophagitis cases in the CEG group than in the SPADE group (30% vs. 15.3%, P=0.19). Similarly, bile reflux (26.7% vs. 7.7%, P=0.08) and residual food (P=0.01) cases occurred more frequently in the CEG group than in the SPADE group. In the CEG group, 13 patients (43.3%) had mild reflux symptoms, while 3 patients (10%) had severe reflux symptoms. In the SPADE group, 3 patients (11.5%) had mild reflux symptoms, while 1 had severe reflux symptoms (absolute difference, 31.8%; 95% confidence interval, 1.11-29.64; P=0.01). Conclusions: A novel modified EG, the SPADE operation, has the potential to decrease gastroesophageal reflux following a PG.

Objective: This study was performed to assess our clinical experience with single-port access (SPA) laparoscopic cystectomy and myomectomy and the surgical outcomes of those procedures at our institution. Methods: The authors evaluated the surgical outcomes of SPA laparoscopic cystectomy in 293 patients and SPA laparoscopic myomectomy in 246 patients. The surgical outcomes comprised operation time, the amount of blood loss during the operation, the change in hemoglobin (before and after the operation), the change in hematocrit (before and after the operation), switching to the multi-port access method, complications, transfusions, and the duration of the postoperative hospital stay. Results: The Pearson correlation coefficient and the Spearman correlation coefficient between the operation time and the amount of blood loss were 0.312 and 0.321 for SPA laparoscopic cystectomy, respectively, and 0.706 and 0.674 for SPA laparoscopic myomectomy, respectively. The drops in hemoglobin and hematocrit were $1.33{\pm}0.78g/dL$ and $4.14%{\pm}2.45%$, respectively, in SPA laparoscopic cystectomy, while the corresponding figures were $1.34{\pm}1.13g/dL$ and $4.17%{\pm}3.24%$ in SPA laparoscopic myomectomy, respectively. Conclusion: This study reported the surgical outcomes of SPA laparoscopic cystectomy and myomectomy and compared them to previously published findings on traditional laparoscopic cystectomy and myomectomy. No significant differences were found in the surgical outcomes between SPA and traditional laparoscopic cystectomy and myomectomy.

Purpose: The purpose of this study was to compare the data comprehensively including not only the clinical and radiographic outcomes but some parameters related to operation between the minimally invasive plate osteosynthesis (MIPO) technique and intramedullary nailing (IMN) for treatment of segmental tibia shaft fractures. Methods: We conducted a retrospective study of 31 patients (mean age, 49.3 years, range, 27-74 years), with a mean follow-up of 14.1 months (range, 12-19 months) with acute segmental tibial fractures (AO 42-C2) who underwent either surgical treatment of MIPO or IMN. In accordance with the Gustilo-Anderson classification, 11 were type I, 5 were type II, and 15 were type III. Initial compartment syndrome was confirmed in 2 cases. Results: There were no statistically significant differences in terms of the patient demographic data between the two groups. The time to definitive fixation was longer in the MIPO group (mean $13.7{\pm}10.9days$; range, 2-27) than in the intramedullary group (mean $5.4{\pm}9.6days$; range, 0-35) with statistically significant difference (p=0.002). Bony union was observed in most of cases but except 5 cases of nonunion were diagnosed (3 in the MIPO vs 2 in IMN, p=0.188). The average bone healing time was 27.1 weeks (10 to 56 weeks) in MIPO group and 23.2 weeks (13 to 66 weeks) in IMN group, respectively (p=0.056). Overall complications were 5 cases in MIPO group and 2 cases in the IMN group. Difference in LEFS was not statistically significant between both groups (p=0.824). Conclusion: This study showed that segmental tibia shaft fractures treated with both MIPO and intramadullary nailing was challenging with relatively high complication rate. A well planned sequential strategy with keeping the soft tissue and personality of fracture in mind is utmost significant as much as the choice of surgical modalities.

Objective : So called "minimally invasive procedures" have evolved from chemonucleolysis, automated percutaneous discectomy, arthroscopic microdiscectomy that are mainly working within the confines of intradiscal space to transforaminal endoscopic technique to remove herniated epidural disc materials directly. The purpose of this study is to assess the result of endoscopic spinal surgery and favorable indication in the thoracolumbar spine. Methods : The records of 71 patients, 73 endoscopic procedures, were retrospectively analysed. Yeung Endoscopic Spine Surgery system with 7 mm working sleeve and $25^{\circ}$ viewing angle was used. The mean follow up period was 6 months [range, 3-9]. Results : Operated levels were from T12-L1 disc down to L5-L6 of S1 disc. Of 71 cases, 2 patients underwent transforaminal endoscopic surgery twice due to recurrence after initial operation. MacNab's criteria was used to assess the outcome. Favorable outcome, excellent of good, was seen in 78% [57 procedures] of the patients. Among 11 fair outcomes, only 1 procedure was followed by secondary open procedure, laminectomy with discectomy. Two of 5 poor outcomes were operated again by same procedure which resulted in fair outcomes. One patient with aggravated cauda equina syndrome remained poor and a lumbar fusion procedure was performed in other patient with poor outcome. There were 2 postoperative discitis that were treated with conservative care in one and anterior lumbar interbody fusion in the other. Conclusion : Evolving technology of mechanical, visual instrument enables minimal invasive procedure possible and effective. The transforaminal endoscopic spinal surgery can reach as high as T12-L1 disc level. The rate of favorable outcome is mid-range among reported endoscopic lumbar surgery series. Authors believe that the outcome will be better as cases accumulate and will be able to reach the fate of standard open microsurgery.
