목적: 슬관절내 이물질은 비록 빈도가 높지는 않으나, 종전에는 이를 제거하기 위해 광범위 관절 절개술 또는 다발성 절개술이 필요함에 따라 수술자로 하여금 당혹한 경험을 갖게 하였다. 저자들은 관절경적 제거 술식을 이용한 슬관절내 이물질 제거에 대하여 임상적 치험과 그 결과를 분석하여 관절경적 제거술식의 유용성을 알아보고자 하였다. 대상 및 방법: 본원에서 1983년 3월부터 2006년 9월까지 총 22례의 슬관절내 이물질에 대하여 관절경적 이물질 제거술을 시행하였다. 성별로는 남자가 16명 여자가 6명 이었고, 슬관절내 이물질의 원인으로 외상이 7례(31.9%), 수술과 관련된 예가 13례(59%), 수술적 치료 후 추적관찰 기간 중 발견된 예가 2례(9.1%)였다. 결과: 이물질의 종류로는 금속성 이물질이 15례(68.1%)로 가장 많았고 비금속성 이물질이 7례(31.9%)였으며 총알, 봉합사, 연필심, 끊어진 강선 등의 다양한 분포를 보였다. 전례에서 관절경적 술식을 이용하여 용이하게 이물질을 제거할 수 있었으며 술 후 관절강직 등의 특이한 합병증은 없었다. 결론: 슬관절내 이물질 제거에 있어서 관절경적 방법은 이물질에 대한 접근의 용이성과 유동성 뿐만 아니라 술후 발생할 수 있는 후유증의 측면에서도 매우 유용한 술식으로 사료된다. 목적: 슬관절내 이물질은 비록 빈도가 높지는 않으나, 종전에는 이를 제거하기 위해 광범위 관절 절개술 또는 다발성 절개술이 필요함에 따라 수술자로 하여금 당혹한 경험을 갖게 하였다. 저자들은 관절경적 제거 술식을 이용한 슬관절내 이물질 제거에 대하여 임상적 치험과 그 결과를 분석하여 관절경적 제거술식의 유용성을 알아보고자 하였다. 대상 및 방법: 본원에서 1983년 3월부터 2006년 9월까지 총 22례의 슬관절내 이물질에 대하여 관절경적 이물질 제거술을 시행하였다. 성별로는 남자가 16명 여자가 6명 이었고, 슬관절내 이물질의 원인으로 외상이 7례(31.9%), 수술과 관련된 예가 13례(59%), 수술적 치료 후 추적관찰 기간 중 발견된 예가 2례(9.1%)였다. 결과: 이물질의 종류로는 금속성 이물질이 15례(68.1%)로 가장 많았고 비금속성 이물질이 7례(31.9%)였으며 총알, 봉합사, 연필심, 끊어진 강선 등의 다양한 분포를 보였다. 전례에서 관절경적 술식을 이용하여 용이하게 이물질을 제거할 수 있었으며 술 후 관절강직 등의 특이한 합병증은 없었다. 결론: 슬관절내 이물질 제거에 있어서 관절경적 방법은 이물질에 대한 접근의 용이성과 유동성 뿐만 아니라 술후 발생할 수 있는 후유증의 측면에서도 매우 유용한 술식으로 사료된다.

Formation of an aneurysm in the sinus of Valsalva of the aortic root is usually due to an area of congenital weakness in its wall. This aneurysm may progressively dilate and rupture into any of the cardiac chambers or into the pericardial cavity. Though this is conventionally treated by surgery, interventional therapy using various closure devices is becoming more common. Embolization of these closure devices may occur. We report a case of embolization of such a device into the left pulmonary artery which during surgical retrieval, unmasked the hidden ventricular septal defect (VSD). Therefore one has to be cautious while making a diagnosis of rupture of the sinus of Valsalva of right coronary sinus without VSD.

이물 섭취 병력을 보이는 다섯 마리 개가 건국대학교 부속 동물병원과 한강 동물병원에 내원하였다. 신체 검사에서 무기력, 식욕 감퇴, 구토 증상을 보였으며 일반 방사선 사진에서 심장 앞쪽 또는 뒤쪽 흉부 식도에 이물이 걸려 있는 것을 확인하였다. 식도의 조영 촬영에서 큰 이물에 의한 식도 팽창을 확인 할 수 있었으며 흉강 내로의 조영제 누수는 관찰 되지 않았다. 위 절개술을 통한 식도 내 이물 제거를 긴 겸자를 이용하여 실시 하였다. 다섯 마리 모두에서 식도 내 이물을 성공적으로 제거하였다. 수술 후 10일 또는 2년에 정기 검진이 마무리 되었으며 수술과 관련한 구토, 연하 곤란, 식욕 저하, 과다 유연과 같은 합병 증상이 없음을 확인하였다.

Purpose: Guidelines in Western countries recommend retrieving ${\geq}15$ lymph nodes (LNs) during gastric cancer resection. This study sought to determine whether the number of examined lymph nodes (eLNs), a proxy for lymphadenectomy, effects survival in node-negative disease. Materials and Methods: The US National Cancer Database (2003-2011) was reviewed for node-negative gastric adenocarcinoma. Treatment was categorized by neoadjuvant therapy (NAT) vs. initial resection, and further stratified by eLN. Kaplan-Meier and Weibull models were used to analyze overall survival. Results: Of the 1,036 patients who received NAT, 40.5% had ${\leq}10eLN$, and most underwent proximal gastrectomy (67.8%). In multivariate analysis, greater eLN was associated with improved survival (eLN 16-20: HR, 0.71; P=0.039, eLN 21-30: HR, 0.55; P=0.001). Of the 2,795 patients who underwent initial surgery, 42.5% had ${\leq}10eLN$, and the majority underwent proximal gastrectomy (57.2%). In multivariate analysis, greater eLN was associated with improved survival (eLN 11-15: HR, 0.81; P=0.021, eLN 16-20: HR, 0.73; P=0.004, eLN 21-30: HR, 0.62; P<0.001, and eLN >30: HR, 0.58; P<0.001). Conclusions: In the United States, the majority of node-negative gastrectomies include suboptimal eLN. In node-negative gastric cancer, greater LN retrieval appears to have therapeutic and prognostic value, irrespective of initial treatment, suggesting a survival benefit to meticulous lymphadenectomy.

One complication related to local anesthesia in the dental clinic is a broken needle. Although rare, a broken needle may be difficult to retrieve. Dental radiographs and 3D CT have been used in the past to confirm the location of a broken needle. We present the case of a broken needle, which was successfully removed using a careful, microscopic approach.

Foreign body (FB) aspiration remains a serious health problem, particularly in children. The complications due to occlusion by FB or related to procedures for removal can lead to morbidity and mortality. Most of the FBs are located in the unilateral bronchus, however, the organic FB can be multiple or bilaterally located when children chewed the FB. Here, we present a case of successful retrieval of bilateral bronchial FBs. Preoperatively, FB in the left main bronchus was diagnosed, however, FB of the right upper bronchus was not definitive on X-ray and CT scan. During the rigid bronchoscopy, occult FB in the right upper bronchus was detected and successfully removed.

Laparoscopic distal gastrectomy has become widespread as a treatment for early gastric cancer in eastern Asia, but a standard method for setting the stomach transection line has not been established. Here we report a novel method of setting this line based on anatomical landmarks. At the start of the operation, two anatomical landmarks along the greater curvature of the stomach were marked with ink: the proximal landmark at the avascular area between the last branch of the short gastric artery and the first branch of the left gastroepiploic artery, and the distal landmark at the point of communication between the right and left gastroepiploic arteries. Just before specimen retrieval, the stomach was transected from the center of these two landmarks toward the lesser curvature. Then, about two-third of the stomach was reproducibly resected, and gastroduodenostomy was successfully performed in 26 consecutive cases. This novel method could be used as a standard technique for setting the transection line in laparoscopic distal gastrectomy.

Video-assisted thoracoscopic surgery (VATS) has been established as the surgical approach of choice for lobectomy in patients with early-stage non-small cell lung cancer (NSCLC). Patients with clinical stage I NSCLC with no lymph node metastasis are considered candidates for VATS lobectomy. To rule out the presence of metastasis to lymph nodes or distant organs, patients should undergo meticulous clinical staging. Assessing patients' functional status is required to ensure that there are no medical contraindications, such as impaired pulmonary function or cardiac comorbidities. Although various combinations of the number, size, and location of ports are available, finding the best method of port placement for each surgeon is fundamental to maximize the efficiency of the surgical procedure. When conducting VATS lobectomy, it is always necessary to comply with the following oncological principles: (1) the vessels and bronchus of the target lobe should be individually divided, (2) systematic lymph node dissection is mandatory, and (3) touching the lymph node itself and rupturing the capsule of the lymph node should be minimized. Most surgeons conduct the procedure in the following sequence: (1) dissection along the hilar structure, (2) fissure division, (3) perivascular and peribronchial dissection, (4) individual division of the vessels and bronchus, (5) specimen retrieval, and (6) mediastinal lymph node dissection. Surgeons should obtain experience in enhancing the exposure of the dissection target and facilitating dissection. This review article provides the basic principles of the surgical techniques and practical maneuvers for performing VATS lobectomy easily, safely, and efficiently.

Transcatheter leadless pacemaker dislodgment is a rare and potentially fatal complication of leadless device implantation. We present the first case of multidetector computed tomography images of leadless pacemaker migration and embolization in the pulmonary middle lobe artery. The patient was managed by percutaneous retrieval of the dislodged device and re-implantation in the appropriate position.

A 25-year-old man presented with a history of pain and crepitus in the right shoulder; he had been previously treated with arthroscopic anterior stabilization using four metallic suture anchors for recurrent traumatic anterior instability 1 year earlier. In this report, we present a patient with recurrent glenohumeral instability combined with anchor-induced arthropathy who was managed with modified arthroscopic transglenoid reconstruction following arthroscopic suture anchor retrieval.
