Pediatric laryngotracheal stenosis occurs by either congenital or acquired causes and usually indicates subglottic stenosis. The main goals of treatment are decannulation, preserving phonation, and normal swallowing function. Various types and degrees of stenosis and combined anomalies would be the main barriers to reaching successful treatment results unless comprehensive understanding of stenosis. Multidisciplinary team approaches encompassing initial assessment, treatment, and postoperative care, are also necessary to achieve the best treatment outcome. Therapeutic approaches are divided into conservative, endoscopic, and open surgical approaches at length, which are not exclusive to each other. Here, an adequate selection of each therapeutic option and postoperative management will be introduced to achieve decannulation without leaving phonatory or swallowing complications.

Gastric neuroendocrine tumors (GNETs, also known as gastric carcinoids) are rare form of hormone-secreting neoplasms that present with varied clinical syndromes. There are four types of GNETs based on size, proliferation, localization, differentiation, and hormone production. Type I GNET is related to autoimmune atrophic gastritis and hypergastrinemia. Type II GNETs are related to multiple endocrine neoplasia (MEN)-1, Zollinger-Ellison syndrome and hypergastrinemia. Type 3 GNETs are not associated with any background pathology, and type 4 GNETs are poorly differentiated tumors. The most useful diagnostic and prognostic marker for gastrointestinal NETs is plasma chromogranin A (CgA) levels. Endoscopic ultrasound is the method of choice to determine tumor size and depth of infiltration. For optimal management, the type, biology, and stage of the tumor must be considered. Here, we provide a comprehensive and up-to-date review of GNETs.

In patients having long-standing ulcerative colitis (UC), the risk of colorectal cancer (CRC) increased compared with general population. Dysplasia is a precancerous lesion of colitic patients, and traditionally total proctocolectomy was considered as a standard therapy to prevent colorectal cancer in UC patients. However, even with ileal pouch-anal anastomosis (IPAA), patients who underwent total proctocolectomy may experience early and late postoperative complications, such as ileus, bleeding, pouchitis, and so on. In addition, the bowel movement after proctocolectomy with IPAA reaches a median of seven times per day, and a considerable proportion of patients require daytime and nighttime pads. Change in the strategy for managing dysplasia started from two early studies, which suggested polypectomy for polypoid dysplasia to prevent CRC in colitic patients. After that, many studies supported that polypectomy should be the first option for the management of polypoid dysplasia. Moreover, recent studies suggested the feasibility of endoscopic submucosal dissection as a therapeutic option for non-polypoid dysplasia, although long term, large studies should be followed.

농흉의 치료에서 흉막박피술 또는 괴사조직 절제에 비디오 흉강경을 사용한 수술(VATS)이 유용한 치료로서 제시되고 있지만 아직은 검증이 필요한 단계이나. 농흉의 시기에 관계없이 시행한 농흥의 흉강경적 치료에 대한 우리의 수술방법과 경험을 보고하고자 한다. 대상 및 방법 : 흉강내 감염을 보이는 40명의 환자에서 흉막박피술과 괴사조직 절제에 비디 흉강경을 사용한 수술을 내시경 세이버(endoscopic shaver system)로 시행하였다 수술전후 결과에 대한 후향적 연구를 시행하였고 이 수술방법의 효과를 평가하였다. 결과. 감염된 흉막액의 배출과 흉박피술 비디 흉강경을 사용한 수술은 40명중 35명에서 성공적으로 시행되었다. 전원 되기 전 술전 증상의 평츈 기간은 23$\pm$1.8일 이었고, 수술을 위해 전과되기 전의 평균 입원기간은 13.5$\pm$1.5일이었다. 실혈량은 200dp서 250 mL 이었다. 흉관 배액은 5$\pm$3일간 필요하였고, 수술후 입원은 5$\pm$0.7 일이었다. 수술사망율은 없었다. 결론 : 비디오 흉강경을 이용한 감염된 흉막액을 배농하고 박피술을 시행하는 것은 섬유성 화농성기의 농흉을 치료하는데 있어 효과적인 치료방법 중의 하나이며, 만성기농흉의 기질화된 유착 때문에 가금 개흉술을 통한 박피술이 필요할 때도 있지만, 이러한 유착자체가 비디오 흉강경을 이용한 배농술과 박피술의 절대적 금기는 아닌 것으로 생각된다.

Endobronchial metastasis of leiomyosarcoma is rare, but it can cause life-threatening complications, such as massive hemoptysis, respiratory failure or even death. The development of new endoscopic modalities allows for effective endobronchial management. We report three patients with endobronchial metastases from advanced leiomyosarcomas which caused bronchial obstruction. The bronchoscopic examinations revealed masses obstructing the left main bronchus in all three patients. After removing the endobronchial tumor via interventional bronchoscopy, there was symptomatic and radiologic improvement. Moreover, the patients were able to undergo additional palliative chemotherapy. Therefore, endobronchial management of endobronchial tumors should be considered in the treatment of endobronchial metastasis, even in patients with advanced malignancies.

Bile leaks are complications that are much more frequent after a high-grade liver injury than after a low-grade liver injury. In this report, we describe the management of bile leaks that were encountered after angiographic embolization in a 27-year-old man with a high-grade blunt liver injury. He had undergone an abdominal irrigation and drainage with a laparotomy on post-injury day (PID) 16 due to bile peritonitis and continuous bile leaks from percutaneous abdominal drainage. He required three percutaneous drainage procedures for a biloma and liver abscesses in hepatic segments 4, 5 and 8, as well as endoscopic retrograde cholangiopancreatography with biliary stent placement into the intrahepatic biloma via the common bile duct. We detected communication between the biloma and the bilateral intrahepatic duct by using a tubogram. Follow-up abdominal computed tomography on PID 47 showed partial thrombosis of the inferior vena cava at the suprahepatic level, and the patient received anticoagulation therapy with low molecular weight heparin and rivaroxaban. As symptomatic improvement was achieved by using conservative management, the percutaneous drains were removed and the patient was discharged on PID 82.

Background: In solid organ transplantation patients, complications of cholelithiasis may run a fulminant course, resulting in high morbidity and mortality under immunosuppression and may even result in rejection. Here, we reviewed medical records of 66 patients in order to determine the outcome of management approach for asymptomatic gallstones in renal transplantation patients. Methods: We retrospectively reviewed clinical courses of 66 cases of renal transplantation performed between 2000 and 2012 at Kosin University Gospel Hospital. Results: Among 66 cases, eight had gallstones before transplantation. Three of these cases had undergone previous cholecystectomy for symptomatic gallstones, one had a simultaneous laparoscopic cholecystectomy and renal transplantation, and four were observed by regular abdominal ultrasonography. One patient was found to have cholangitis, and endoscopic retrograde biliary drainage was performed, resulting in alleviation of symptoms. Among 58 cases without preoperative gallstones, three developed gallstones after transplantation. One patient had cholecystitis, and the symptoms subsided after conservative treatment. Conclusions: For patients with asymptomatic gallstones who are awaiting renal transplantation, expectant management should be considered.

Iatrogenic perforations are severe complications of gastrointestinal endoscopy; therefore, their management should be adequately planned. A 77-year-old man with a history of diverticulosis underwent a colonoscopy for anemia. During the procedure, an iatrogenic perforation occurred suddenly in the sigmoid colon, near a severe angle among the numerous diverticula. Through-the-scope clips were immediately applied to treat it and close mucosal edges. Laboratory tests showed increased levels of inflammation and infection, and although there were no complaints of abdominal pain, the patient had an extremely distended abdomen. A multidisciplinary board began management based on a conservative approach. Pneumoperitoneum was treated with computed tomography-assisted drainage. After 72 hours, his intestinal canalization and laboratory tests were normal. Though this adverse event is rare, a multidisciplinary board should be promptly gathered upon occurrence, even if the patient appears clinically stable, to consider a conservative approach and avoid surgical treatment.

Purpose: Percutaneous endoscopic gastrostomy (PEG) tube placements are commonly performed pediatric endoscopic procedures. Because of underlying disease, these patients are at increased risk for airway-related complications. This study compares patient characteristics and complications following initial PEG insertion with general endotracheal anesthesia (GETA) vs. anesthesia-directed deep sedation with a natural airway (ADDS). Methods: All patients 6 months to 18 years undergoing initial PEG insertion within the endoscopy suite were considered for inclusion in this retrospective cohort study. Selection of GETA vs. ADDS was made by the anesthesia attending after discussion with the gastroenterologist. Results: This study included 168 patients (GETA n=38, ADDS n=130). Cohorts had similar characteristics with respect to sex, race, and weight. Compared to ADDS, GETA patients were younger (1.5 years vs. 2.9 years, p=0.04), had higher rates of severe American Society of Anesthesiologists (ASA) disease severity scores (ASA 4-5) (21% vs. 3%, p<0.001), and higher rates of cardiac comorbidities (39.5% vs. 18.5%, p=0.02). Significant associations were not observed between GETA/ADDS status and airway support, 30-day readmission, fever, or pain medication in unadjusted or adjusted models. GETA patients had significantly increased length of stay (eβ=1.55, 95% confidence interval [CI]=1.11-2.18) after adjusting for ASA class, room time, anesthesia time, fever, and cardiac diagnosis. GETA patients also had increased room time (eβ=1.20, 95% CI=1.08-1.33) and anesthesia time (eβ=1.50, 95% CI=1.30-1.74) in adjusted models. Conclusion: Study results indicate that younger and higher risk patients are more likely to undergo GETA. Children selected for GETA experienced longer room times, anesthesia times, and hospital length of stay.

Psychogenic dysphagia is a deglutition disorder characterized by a fear of swallowing, with no structural or functional causes. This report presents the case of a young male patient who had severe malnutrition due to psychogenic dysphagia and was provided visual biofeedback using fiberoptic endoscopic evaluation of swallowing (FEES). A healthy 25-year-old man presented to our clinic with a complaint of throat discomfort when swallowing that had started 6 months prior. As the symptoms worsened, he became fearful of food spreading to his lungs after swallowing and the development of respiratory difficulties. His food intake gradually decreased, resulting in a weight loss of 20 kg within 2 months. Evaluation of organic and other functional causes of dysphagia was performed, but no abnormalities were detected. The sensation of a lump in his throat, fear of swallowing, and anxiety were transformed into somatic symptoms. The patient was diagnosed with psychogenic dysphagia. After visual biofeedback by a physician who performed FEES, the patient resumed eating normally and increased his food intake. If routine tests do not reveal structural or functional causes of dysphagia, assessment of a psychogenic swallowing disorder should be considered. FEES can help in the diagnosis and management of psychogenic dysphagia.
