A Le Fort I osteotomy is a common procedure for correcting dental and facial deformities in orthognathic surgery. In rare cases, a delayed hemorrhage can occur as early as several hours or up to 12 weeks, postoperatively. The most frequently involved blood vessels in a delayed hemorrhage are the descending palatine artery, the internal maxillary artery, and the pterygoid venous plexus of veins. Intraoral bleeding accompanied by severe epistaxis in these cases makes it difficult to locate the precise bleeding focus. Eventual uncontrolled bleeding would require Merocel packing or surgical intervention. In general, a severe late postoperative hemorrhage is most effectively managed by angiography and embolization. Herein we describe a delayed hemorrhage case in which the cause was not evident on angiography. We were able to detect the bleeding point through an endoscopic nasal approach and treat it using direct cauterization.

식도이물은 식도질환 중에서 우리가 쉽게 경험할 수 있는 질환 중의 하나로써 대부분의 경우에 있어서는 식도경에 의한 이물의 적출로써 별다른 문제없이 치유된다. 허나 드물게 식도천공, 객도주위농양, 종격동염, 기흉, 농흉, 폐농양 및 피하기종 등과 같은 합병증이 병발하기도 하며 이 때 조기에 진단하여 신속한 처치를 하지 않으면 생명을 위협하여 불행한 결과를 초래하는 경우가 발생하기도 한다. 이물에 의한 식도천공은 그것이 날카로운 금속성 물질 혹은 골편이거나 장기간 체류함에 따라 식도점막에 괴사를 일으키는 경우에 발생한다. 최근에 저자들은 식도에서 예리한 생선뼈를 제거한 후에 식도주위 농양이 발생한 환자를 경부 종격절제술로 배농한 후에 지속적인 세척을 시행함으로써 좋은 결과를 얻었기에 이를 문헌고찰과 함께 보고하는 바이다.

Mandible angle ostectomy is the most widely-operated facial contour surgery. We experienced a rare case of necrotizing fasciitis of the lower leg following mandible angle ostectomy. A 20 years old female visited our department 5 days after mandible angle ostectomy. At the time, she was diagnosed as sepsis and on her 2nd admission day, she was diagnosed as necrotizing fasciitis on her left leg. She was treated by fasciotomy and necrotized tissue removal. Necrotizing fasciitis is a rare complication of any kinds of operation but once it develops, it causes fatal results, especially to cosmetic surgeries. Early diagnosis and aggressive operation is known as only treatment for the disease.

기관무명동맥루는 매우 드물지만 높은 사망률을 보이는 질환으로, 장기간의 기관절개술이나 기관내 삽관후 합병증으로 발생한다. 대량 출혈로 인해 기도폐쇄 및 출혈성 쇼크로 생명의 위협이 초래되기 때문에 조기 진단과 즉각적인 치료가 반드시 필요하다. 후두 협착에 대한 수술을 위해 가능한 한 기관의 보존이 필요한 환자에 발생한 기관무명동맥루 환자에서 연골막을 포함한 늑연골을 이용한 기관성형술을 시행하였기에 보고하는 바이다.

Radiation therapy (RT) has improved patient outcomes, but treatment-related complication rates remain high. In the conventional 2-dimensional and 3-dimensional conformal RT (3D-CRT) era, there was little room for toxicity reduction because of the need to balance the estimated toxicity to organs at risk (OARs), derived from dose-volume histogram data for organs including the lung, heart, spinal cord, and liver, with the planning target volume (PTV) dose. Intensity-modulated RT (IMRT) is an advanced form of conformal RT that utilizes computer-controlled linear accelerators to deliver precise radiation doses to the PTV. The dosimetric advantages of IMRT enable better sparing of normal tissues and OARs than is possible with 3D-CRT. A major breakthrough in the treatment of esophageal cancer (EC), whether early or locally advanced, is the use of proton beam therapy (PBT). Protons deposit their highest dose of radiation at the tumor, while leaving none behind; the resulting effective dose reduction to healthy tissues and OARs considerably reduces acute and delayed RT-related toxicity. In recent studies, PBT has been found to alleviate severe lymphopenia resulting from combined chemo-radiation, opening up the possibility of reducing immune suppression, which might be associated with a poor prognosis in cases of locally advanced EC.

세균성 복막염은 신증후군 환아의 생명을 위협하는 중요한 감염성 합병증으로 초기에 광범위한 항생제 병용치료가 이루어져야한다. 저자들은 신증후군 진단 후 치료가 지연된 환아에서 발생한 복막염 및 복부농양 증례를 경험하였기에 보고하는 바이다.

신 주위 농양은 증상이 비특이적이고 다양하여 임상적으로 진단이 어렵고 치료가 늦어지기 쉬워 합병증과 사망률이 높은 질환이므로, 발열이 지속되는 경우에 감별 진단해야 하는 질환이다. 초음파 촬영술, 전산화 단층 촬영술 등은 신 주위 농양을 조기에 진단하고 적절한 치료 방향을 정하는데 유용하며, 치료 방법으로 항생제 외에 경피적 농흡인, 배농 및 수술 등의 처치가 필요하다. 저자들은 발열이 9일 동안 지속된 환아에서 경피적 배농술로 치료한 신 주위 농양 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

The complications of a tracheotomy are caused by inappropriate surgical techniques, unsuitable cannula selections, and improper wound care. Among these, the solutions to problems of surgical technique and wound care have been reported in many articles. Detailed methods for preventing complications by the cannula are rare. The authors tried to find a way of preventing complications by the cannula Materials and Methods : The authors analized complications in 70 patients who had a temporary tracheotomy and were wearing a cannula. And the complications were compared between 4 commercial cannulas used in our institute. The examination methods used were a simple neck lateral radiogram and flexible endoscopy. Results： The order of most commonly found complications were as followed; at the suprastoma, end of cannula, level of tracheotomy, and infrastoma. Among 4 cannulas, a particular product had so many complications compared to the other 3 cannulas. The most common cause of complications was unsuitable cannula. All complications were cured with no sequelae. Flexible endoscopy is far superior to radiologic exam for detecting tracheal complications. Conclusion： Flexible endoscopy through the tracheostoma is very helpful for detecting complications early and determining if a proper cannula is used, which can prevent further complications such as stenosis or innominate artery rupture. The authors, therfore, recommend using the flexible endoscopy to all patients wearing tracheotomy tubes. Some complications can simply be prevented by replacing the one to another cannula properly fit for the individual patients. Various cannulas should be prepared at the hospital because the tracheal curvature and distance of skin to trachea are individualized.

Purpose: The Korean Gastric Cancer Association (KGCA) has been conducting nationwide surveys on patients with surgically treated gastric cancer, every 5 years, since 1995. This study details the results of the survey conducted in 2019. Materials and Methods: This survey was conducted from March to December 2020 using a standardized case report form, which was sent to every member of the KGCA via e-mail. We collected data on 54 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. We compared the results of the 2019 survey with previous surveys. Results: Data of 14,076 cases were collected from 68 institutions. The mean patient age was 62.9 years and the proportion of patients who were aged ≥71 years increased from 9.1% in 1995 to 28.8% in 2019. The proportion of upper-third tumors steadily increased from 11.2% in 1995 to 20.9% in 2019 and that of early gastric cancer increased from 57.7% in 2009 to 63.6% in 2019. Regarding operative procedures, a total laparoscopic approach was used in more than half of the cases (55.1%) in 2019. The most common anastomotic method was the Billroth II procedure (45.0%) after distal gastrectomy and double tract reconstruction (81.2%) after proximal gastrectomy in 2019. The postoperative mortality rate was 1.0%, and the overall postoperative complication rate was 14.5%. Conclusions: The results of the 2019 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for gastric cancer research in the future.

Spontaneous intramural hematoma is a rare complication of oral anticoagulants, and its incidence is expected to increase because of the increasing number of elderly patients undergoing anticoagulant therapy. Clinical manifestations of spontaneous intramural hematoma vary from mild abdominal pain to intestinal obstruction or acute abdomen. Early diagnosis is important because most patients can be treated successfully without surgery. The role of endoscopy in the diagnosis of intramural hematoma is not well established because almost all cases are diagnosed non-invasively with computed tomography scans. However, confirmation of the intramural hematoma through direct visualization of the involved bowel mucosa is helpful, if the imaging diagnosis is uncertain. We report a case of anticoagulant-induced spontaneous intramural hematoma, which was diagnosed using endoscopy, with relevant literature review.
