목적 악성대장협착에서 스텐트 설치 후 시행한 단단계 수술의 결과를 평가하고자 하였다. 대상과 방법 2009년 1월부터 2018년 1월까지, 악성대장협착으로 투시장치 하 스텐트를 설치하여 장세척을 한 후 수술을 시행한 46명의 환자(남:여 = 28:18, 평균 67.2세)를 대상으로 하였다. 그중 31명은 복강경수술, 15명은 개복수술을 시행하였으며, 수술 결과를 후향적으로 분석하였다. 평균 38.9개월의 추적관찰 기간 동안, 무재발생존율과 전체생존율을 구하였고, 예후인자를 알아보았다. 결과 스텐트 설치 후 평균 10.2일 후에 수술을 시행하였으며, 전례에서 성공적으로 스텐트를 포함한 종양 절제 후 문합이 가능하였다. 수술 후 평균 입원기간은 11일이었다. 6명의 환자(13%)에서 수술 중 혹은 수술 후 병리 소견에서 장천공이 관찰되었다. 추적 기간 동안 10명의 환자(21.7%)에서 종양이 재발하였으며, 장천공이 관찰되었던 6명의 환자 중 5명에서 재발이 발생하였다. 장천공은 무재발생존율에 유의미한 영향을 미쳤다(p = 0.010). 결론 악성대장협착에서 스텐트 설치 후 시행한 단단계 수술은 효과적인 치료 방법으로 생각된다. 스텐트와 연관된 장천공이 재발의 위험인자였다.

목적: 진행성 암 환자에서 악성장폐색은 구역, 구토, 통증을 비롯한 소화기계 증상을 유발하여 삶의 질을 저하시킨다. 악성장폐색의 증상 조절을 위해 octreotide를 투여한 후의 효능에 대한 보고들이 발표되었고, 저자들은 악성장폐색이 있는 환자에게 보존적 치료에 octreotide를 추가하여 투여시의 효과와 안전성을 알아보고자 하였다. 방법: 의무기록을 통하여 일반적인 치료로 호전이 없어 octreotide를 추가한 악성장폐색의 환자 29명에서 octretide를 0.1 mg을 시작으로 증상 조절될 때까지 증량하여, 약 투여 전후의 통증의 변화, 구토 횟수의 변화, 비위관 삽입환자의 경우 배액량의 변화를 조사하였다. 결과: Octreotide 투여량의 중간 값은 0.2 mg이고 0.1~0.6 mg의 범위이며, 약제 투여시점으로부터 사망까지 2일에서 103일의 범위로 중간 값은 20일이었다. 약제 투여 전의 VAS는 평균 5.6$\pm$1.2이고, 약 투여 후 VAS의 평균은 2.7$\pm$1.0이었으며 통계적으로 유의한 감소를 보였다(P<0.05). 약제 투여 전의 구토 횟수는 평균 3.6회/일$\pm$2.5이었고 약 투여 후에는 0.4회/일$\pm$0.8로 감소되었고, 통계적으로 유의한 감소를 보였다(P<0.05). 약제 투여전에 비위관 삽입 환자는 평균 975$\pm$1,083 cc/일의 배액이 확인되었고, 약 투여 후에는 평균 115$\pm$196 cc/일로 유의하게 감소하였다(P<0.05). 결론: 일반적인 약물치료에 반응이 없는 악성장폐색환자에서 octretide의 추가 투여는 효과적이며 안전하였다. 악성장폐색 환자의 증상조절을 위해서 octreotide의 추가 투여를 적극적으로 고려해야 하겠다.

Advanced malignant hilar biliary obstruction (MHBO) with inaccessible papilla poses a significant challenge to endoscopists, as drainage of multiple liver segments may be warranted. Transpapillary drainage may not be feasible in patients with surgically altered anatomy, duodenal stenosis, prior duodenal self-expanding metal stent, and after initial transpapillary drainage, but require re-intervention for draining separated liver segments. Endoscopic ultrasound-guided biliary drainage (EUS-BD) and percutaneous trans-hepatic biliary drainage are the feasible options in this scenario. The major advantages of EUS-BD over percutaneous trans-hepatic biliary drainage include a reduction in patient discomfort and internal drainage away from the tumor, thus reducing the possibility of tissue or tumor ingrowth. With innovations, EUS-BD is helpful not only for bilateral communicating MHBO but also for non-communicating systems with bridging hilar stents or isolated right intra-hepatic duct drainage by hepatico-duodenostomy. EUS-guided multi-stent drainage with specially designed cannulas and guidewires has become a reality. A combined approach with endoscopic retrograde cholangiopancreatography for re-intervention, interventional radiology, and intraductal tumor ablative therapies has been reported. Stent migration and bile leakage can be minimized with proper stent selection and technique, and stent blocks can be managed with EUS-guided interventions in a majority of cases. Future comparative studies are required to establish the role of EUS-guided interventions in MHBO as rescue or primary therapy.

Background/Aims: Patients with acute cholecystitis (AC) after metallic stent (MS) placement for malignant biliary obstruction (MBO) have a high surgical risk. We performed percutaneous transhepatic gallbladder aspiration (PTGBA) as the first treatment for AC. We aimed to identify the risk factors for AC after MS placement and the poor response factors of PTGBA. Methods: We enrolled 401 patients who underwent MS placement for MBO between April 2011 and March 2020. The incidence of AC was 10.7%. Of these 43 patients, 37 underwent PTGBA as the first treatment. The patients' responses to PTGBA were divided into good and poor response groups. Results: There were 20 patients in good response group and 17 patients in poor response group. Risk factors for cholecystitis after MS placement included cystic duct obstruction (p<0.001) and covered MS (p<0.001). Cystic duct obstruction (p=0.003) and uncovered MS (p=0.011) demonstrated significantly poor responses to PTGBA. Cystic duct obstruction is a risk factor for cholecystitis and poor response factor for PTGBA, whereas covered MS is a risk factor for cholecystitis and an uncovered MS is a poor response factor of PTGBA for cholecystitis. Conclusions: The onset and poor response factors of AC after MS placement were different between covered and uncovered MS. PTGBA can be a viable option for AC after MS placement, especially in patients with covered MS.

A total of 362 bile samples from 104 patients with evidence of biliary tract obstruction were submitted for diagnostic cytology from January, 1989 to April, 1991. The patients were classified based on the obstructive cause, and the cytologic results were reviewed. 298 of the specimens were from patients with intrabiliary malignant structure, and 17 were from patients with extrabiliary malignant compression or benign biliary obstruction. Bile cytology was positive for carcinoma in 42 samples from patients with intrabiliary malignant stricture, and the diagnostic sensitivity was 14%. There were no false positive cases. We concluded that the cause of low sensitivity was degenerative change of cell due to prolonged sampling time. What is noteworthy was the high prevalence of Clonorchis sinensis eggs, being detected in 25 patients with intrabiliary malignancy, supporting the association between clonorchiasis and biliary tree malignancy.

냉동 치료의 장점은 비침습적이며 통증이 없고 재치료가 가능하기 때문에 수술 고위험군, 재발환자 등에서 국소암 치료로서 적용될 수 있다는 점이다. 외부영상과 굴곡내시경을 통하여 위치를 파악하고 내시경으로 표적부위만을 냉동하기 때문에 주변조직의 손상이 거의 없으며 심폐 기능에 큰 위험을 주지 않는다. 처음 치료 후에도 치료를 한 부위나 다른 부위에도 여러 번의 추가적 치료가 가능하므로 치료로 불완전한 부분을 추가적으로 치료를 하여 좋은 결과를 얻을 수 있다. 냉동 수술의 특성을 잘 이용하여 적절한 환자에게 적용한다면, 기관-기관지의 폐색을 일으키는 악성 종양 환자들에게 좋은 치료방법의 하나라고 생각된다.

Malignant bowel obstruction (MBO), an occasional complication in patients with advanced urological cancer, causes gastrointestinal symptoms such as nausea and vomiting leading to suffering which severely impairs quality of life (QOL). Drug therapy, especially octreotide, a synthetic analog of somatostatin, is reportedly effective in controlling the symptoms of MBO. In the present study, we administered octreotide to urological cancer patients with MBO and evaluated the improvement of subjective symptoms, oral intake, and nasogastric intubation. Fourteen terminally ill urological cancer patients suffering with MBO were included (age range 55-92, 10 male, 4 female). Octreotide was administered at $300{\mu}g/day$ to those patients subcutaneously as a continuous injection. Significant improvements in subjective symptoms were observed in thirteen patients (92.8%), and ten patients (71.4%) were able to resume oral intake. Four patients required nasogastric drainage before the administration of octreotide, but nasogastric intubation was discontinued in all these cases after the use of octreotide. Early initiation of octreotide resulted in better improvement of MBO symptoms, and no adverse event was observed in any of the patients. These results revealed that $300{\mu}g/day$ dose of octreotide is safe and effective for managing gastrointestinal symptoms of terminally ill urological cancer patients with MBO. We also recommend starting the treatment with ocreotide as soon as MBO is diagnosed.

Primary tumors of the heart are extremely rare, and about 25 per cent of primary cardiac tumors are malignant. Recently, We experienced a case of primary cardiac liposarcoma occurred on the right ventricular outflow tract and extended into the main pulmonary artery. The patient was 57 year-old man and the chief complaints was severe exertional dyspnea. Emergency operation to relieve the right ventricular outflow tract obstruction was performed under cardiopulmonary bypass. The tumor was 5$\times$4$\times$3 cm in size and infiltrated into the right ventricle and ventricular septum. The tumor in the main pulmonary artery was removed without any difficulty but the on the right ventricular outflow tract was difficult to remove completely. The patient was recovered without any specific problems. After successful surgical resection and postoperative radiotherapy the patient discharged with good condition. Herein, the clinical characteristics of cardiac liposarcoma, the problems in differential diagnosis, the prognosis and current therapy are reviewed.
