A 12-year-old boy with severe periumbilical pain visited the emergency room. Physical examination, abdominal ultrasonography, colonoscopy and CT, identified a lesion of sigmoid colon. Endoscopic biopsy showed a signet ring cell carcinoma of the sigmoid colon. On explorative laparotomy, cancer invasions of the adjacent structures and metastases on peritoneal wall were noticed. We performed palliative loop-ileostomy. He underwent chemotherapy and radiotherapy for 3 months. The second case was a 16-year-old boy with abdominal pain and hematochezia, transferred to our hospital with the diagnosis of acute appendicitis with periappendiceal abscess. Although he underwent appendectomy, the abdominal pain persisted. Digital rectal examination revealed a lumen-obstructing fungating mass in the rectum. Endoscopic biopsy revealed a adenocarcinoma. Cancer invasion of the adjacent structures and metastases involving the mesentery of the small intestine were found at laparotomy. A palliative procedure, a Hartmann's operation and end-colostomy at the sigmoid colon were performed. The patient died 8 month later due to pneumonia and sepsis. Chemotherapy was not applied.

현대의학의 발달에 따라 병인을 규명하기 위하여 세밀한 관찰과 자료획득이 가능한 각종 내시경이 대두되기에 이르렀다. 이의 일종인 내시경적 성대경으로 종래에는 보기 힘들었던 병변의 관찰은 물론 사진촬영이 동시에 이루어질 수 있어서 병변의 조기발견과 함께 귀중한 자료가 얻어질 수 있게 되었다. 과거 5년 동안 이화여자대학교 의과대학 부속병원 이비인후과 외래에서 시행한 성대경 사용경험에 따른 장단점과 사진촬영으로 얻은 자료를 중심으로 그 결과를 보고하는 바이다. 1) 간접후두경으로 관찰하기 힘들었던 병변을 보다 명확하게 관찰할 수 있었다. 2) 사진촬영 결과를 환자에게 제시할 수 있어서 치료전후의 상태를 확인시킬 수 있었다. 3) 확대된 성대상을 관찰할 수 있어서 미세한 병변의 감별이 용이하였다. 4) 성대관찰시간이 단축되고 조작이 간편하여 외래에서 사용하기 편리하였다.

횡격막은 횡격막 신경과 동측의 하 흉벽 늑간신경의 지배를 받는다. 상완신경총의 적출 손상을 가진 환자에서 신경총의 일부 신경의 신경이식술에 횡경막 신경의 신경 이식편이 종종 이용된다. 이와 같이 횡격막 신경이 신경이식편으로 사용된 환자에서 횡격막 신경의 탈신경으로 인하여 발생하는 횡격막의 위치 및 운동의 변화를 연구하였다. 대상 및 방법 : 어께의 둔상으로 상완신경총의 적출 손상 때문에 동측의 횡격막 신경으로 근피부신경에 신경이식술을 시행한 13예를 대상으로 하였다. 흉강경 수술방법으로 흉강 내 횡격막 신경을 박리하고 횡격막 바로 위에서 횡격막 신경을 절단하여 경부 절개창을 통해서 외부로 끌어낸 다음 피하 터널을 통해서 동측의 근피부신경에 이식하였다. 엑스선 투시검사와 흉부 엑스선 촬영으로 수술 전후의 횡격막 위치 및 운동 상태를 조사하였다. 결과 : 흉강경을 이용하여 횡격막 신경을 박리 절단하는데 기술적 어려움이나 경미한 합병증도 없었다. 횡격막 신경의 절단 직후에는 횡격막이 평균 1.7 늑간 정도 올라가 있었으나, 엑스선 투시검사에서 흡기시 횡격막의 역행성 운동은 보이지 않았다. 1.5개월 이후의 엑스선 검사에서 횡격막의 위치는 수술 전에 비해 유의한 차이 없을 정도(평균 0.9 늑간 차이; p＝NS로 복원되었다. 횡격막 신경의 절단으로 횡격막의 운동 범위는 탈신경 전에 비해 유의한 차이가 없었다. 결론 : 횡격막 신경의 차단으로 인한 탈신경 후 횡격막의 운동기능은 남아 있었으며 횡격막의 위치는 시간이 경과함에 따라 어느 정도 회복되는 현상을 보였다. 그러나 폐활량이 계속 감소된 소견은 횡격막의 흡기력이 완전히 회복되지 않았음을 추정할 수 있다.

A four-year old, intact male, mixed-breed dog had a history of chronic snoring sound and dyspnea. Based on the results of computed tomography, the patient was diagnosed as nasopharyngeal stenosis. Balloon dilatation in the area of stenosis was performed using a balloon dilator inserted retrograde fashion through the working channel of an endoscope. Clinical signs were relieved but reappeared after 3 weeks. Thirty-four days following the first balloon dilatation treatment, a second procedure was performed; the balloon catheter was inserted in antegrade fashion through the left nostril and was filled with contrast agent under fluoroscopic guidance. Because of the relapse of clinical signs after 6 months, the patient received additional balloon dilatation procedure by the antegrade approach. At the one-year follow-up, the owner said that the clinical signs of nasopharyngeal stenosis had been completely resolved. Balloon dilatation could be a minimally invasive and effective treatment for nasopharyngeal stenosis, although the repetition of the procedure may be required.

Guillain-Barre syndrome (GBS) after trauma and general orthopedic surgery is rare. A 74-year-old woman showed ascending paralysis symmetrically, dysarthria, dysphagia and areflexia on 14 days after minimally invasive endoscopic thermoannuloplasty on L4-5 level. Brain and lumbar magnetic resonance imaging demonstrate no abnormal findings. The electrodiagnostic study showed prolonged distal motor, sensory latencies and F-wave latencies and reduced amplitude of compound muscle action potential in nerves of upper and lower extremities. In the cerebrospinal fluid (CSF) examination, total protein and IgG were increased. We diagnosed Guillain-Barre Syndrome based on clinical features, electrodiagnostic study and CSF examination and the patient improved symptoms after immunoglobulin injection and rehabilitation. Because the occurrence of GBS after minimally invasive procedure has not been reported, we report a case of GBS after minimally invasive procedure with literature review.

Percutaneous endoscopic gastrostomy (PEG) is widely used to provide nutritional support for patients with dysphagia and/or disturbed consciousness preventing oral ingestion, and PEG tube placement is a relatively safe and convenient non-surgical procedure performed under local anesthesia. However, the prevention of PEG-insertion-related complications is important. A 64-year-old man with recurrent pneumonia underwent tracheostomy and nasogastric tube placement for nutritional support and opted for PEG tube insertion for long-term nutrition. However, during the insertion procedure, needle puncture had to be attempted twice before successful PEG tube placement was achieved, and a day after the procedure his hemoglobin had fallen and he developed hypotension. Abdominal computed tomography revealed injury to a pancreatic branch of the superior mesenteric artery (SMA) associated with bleeding, hemoperitoneum, and pancreatitis. Transarterial embolization was performed using a microcatheter to treat hemorrhage from the injured branch of the SMA, and the acute pancreatitis was treated using antibiotics and supportive care. The patient was discharged after an uneventful recovery. Clinicians should be mindful of possible pancreatic injury and bleeding after PEG tube insertion. Possible complications, such as visceral injuries or bleeding, should be considered in patients requiring multiple puncture attempts during a PEG procedure.

Purpose: We aimed to analyze the effectiveness and safety of low-dose midazolam and ketamine combination for upper gastrointestinal endoscopy (UGIE) in children. Methods: The study included the children (n=425, $10.78{\pm}3.81years$) who underwent UGIE for diagnostic purpose during 1 year period. All children were sedated with low dose midazolam (0.1 mg/kg) and ketamine (0.5 mg/kg) intravenously. Effectiveness of the sedation and complications during the procedure and recovery period were recorded. Results: Endoscopic procedure was successfully completed in 414 patients (97.4%; 95% confidence interval, 95.8-98.9). $Mean{\pm}standard$ deviation (SD) duration of procedure was $6.36{\pm}1.64minutes$ (median, 6.0 minutes; range, 4-12 minutes). Minor complications occurred during the procedure in 39.2% of the patients. The most common complication was increased oral secretion (33.1%). No major complications were observed in any patient. Age and Ramsay sedation scores of patients with complications during the procedure were lower than the others ($9.49{\pm}4.05years$ vs. $11.61{\pm}3.43years$, p=0.002 and $2.10{\pm}1.46$ vs. $4.37{\pm}1.16$, p=0.001). Mean recovery time was 22 minutes (range, 10-90 minutes; $mean{\pm}SD$, $25{\pm}12.32minutes$). Minor complications developed during recovery in 60.1% of the patients. The most common complication was transient double vision (n=127, 30.7%). Emergence reaction was observed in 5 patients (1.2%). Conclusion: The procedure was completed with high level of success without any major complication in our study. Combination of low-dose midazolam and ketamine is a suitable sedation protocol for pediatric endoscopists in UGIE.

Endoscopic transthoracic sympathectomy (ETS) has recently become estabilished as a successful treatment for severe palmar and axillary hyperhidrosis. Descriptions have been published of neurolytic, operative and alternative endoscopic procedures involving thermocoagulation, laser coagulation, or or nonvideo-assisted ganglionectomy using equipment not widely available, with low morbidity and excellent results. All methods have advantage and disadvantages. A 19-year-old male who suffered from severe hyperhidrosis on face, palms and axillary areas, has been initially treated with stellate ganglion block in other pain clinic. He was transfered to our pain clinic for endoscopic thoracic sympathectomy. The patient was intubated left side 34 Fr. double lumen tube and positioned left semi-lateral position for right sympathectomy. Right side pneumothorax was created by clamping the ipsilateral side of the double lumen tube and aspiration of air. 11-mm trocar was introduced through incision at the third intercostal space in anterior axillary line, and then additional two 11-mm and 5-mm trocar was introduced through second and fifth intercostal space in mid axillary line. The lung was gently retracted and the parietal pleura over the heads of the appropriate ribs excised using 5-mm sharp insulated coagulating microprocesss. The T4, T3, and T2 ganglions, as well as accompanying rami communicantes, and other branchs arising from upper thoracic nerves to the brachial plexus and surrounding tissues were carefully dissected, coagulated. During sympathectomy, skin temperature of middle was continuously monitored. Elevation of palmar skin temperature intraoperatively indicated an adequate sympathectomy with a definite therapeutic effect. A No. 28 Fr. thoracotomy tube was introduced through a troca under video guidance, placed under water seal after the lung was reinflated. the controlateral side was performed same procedure. After bilateral sympathectomy, chest tubes were removed, and then, he was discharged 2 days after operation with great satisfaction. The ETS provides a well-tolerated, cost-effective alternative to thoracic sympathectomy for primary hyperhidrosis and sympathetic mediated neuropathic pain disorder. And T2 ganglion is considered the key ganglion for the treatment of primary hyperhidrosis. The low incidence of compensatory sweating may by explained by the limited extent of the sympathectomy.

Purpose: This study was done to clarify effects of bispectral index monitoring sedative administration, compared to MOAA/S (Modified Observer's Assessment of Alertness and Sedation), on conscious sedation, physiological stability and recovery time for patients undergoing endoscopic submucosal dissection. Methods: Participants In this study were patients who underwent endoscopic submucosal dissection because of early gastric cancer. Participants were assigned randomly to an experimental group receiving sedatives based on bispectral index monitoring or to a control group with the MOAA/S instrument. Movements, belching, memory, pain, discomfort, physiological stability (MBP, PR, $SpO_2$), and recovery time were measured during the treatment and recovery. Data were analyzed using Spearman partial correlation coefficient analysis, Mixed model and Wilcoxon rank sum test to determine differences in the parameters. Results: There were no statistically significant differences between the two groups for conscious sedation(movement, belching, memory, pain, or discomfort), physiological stability and recovery time. Conclusion: The results of this study indicate that no differences were found between the two types of monitoring. Thus, use of a bispectral index monitor in clinical practice enabling medical staff to readily assess the conscious sedation of for these patients is expected to be increasingly used as an objective assessment tool for conscious sedation for patient safety.
