We are experienced one case of \ulcornerinchu" method operation for chronic thoracic empyema with bronchopleural fistula. A 30-years old male was admitted to our hospital because of right thoracic empyema. In spite of pleural tube drainage, the right entire lung was poorly expanded. The right upper lobectomy and decortication for visceral side of empyema peel were done but expansion of right middle and lower lobe was not enough to fill the pleural space remained Extraperiosteal detachment without performing thoracoplasty was done as the method proposed by Kinchu. The patient recovered without significant problem and the good expansion of remained lung with acceptable pulmonary function was obtained.ined.

Massive chylous leakage is a rare postoperative complication that can prolong hospital stay and cause secondary morbidities. Conservative management strategies are the treatment of choice; however, radiation therapy (RT) can be used as an alternative for cases that are refractory to conservative treatment. Herein, we report a 69-year-old female patient who suffered from massive chylous leakage after subtotal gastrectomy. Due to persistent massive chylous leakage, she was scheduled to undergo low-dose RT. Radiation was delivered with a daily dose of 1 Gy, using an anterior-posterior and posterior-anterior beam arrangement. The clinical target volume encompassed the entire lymph node area of the D2 dissection. RT was completed at the total dose of 8 Gy because the amount of chylous leakage declined rapidly. Percutaneous drainage tube was removed after 3 days of RT. The patient did not complain of any symptoms related to massive chylous leakage 2 years after the completion of RT.

Department of Internal Medicine, The Catholic University of Korea College of Medicine, Seoul, Korea Purpose: Malignant bowel obstruction causes gastrointestinal symptoms and leads to diminished quality of life in patients with advanced cancer. Several studies have shown the efficacy of octreotide for the relief of malignant bowel obstruction-related symptoms. The aim of this study is to assess the efficacy and safety of octreotide in patients with malignant bowel obstruction. Methods: We retrospectively reviewed medical records of twenty nine patients who had suffered from malignant bowel obstruction without clinical improvement of conservative care and subsequently, received octreotide treatment. Initial dosage of octreotide was 0.1 mg/day, and dose was escalated depending on the clinical effect. For each patient, we assessed visual analogue scale (VAS) of pain, number of vomiting episode, and amount of nasogastric tube drainage. Results: Median dosage of octreotide was 0.2 mg/day (range 0.1~0.6), and median duration from initial medication to death was 20 days (range 2~103). VAS before and after octreotide treatment were 5.6$\pm$1.24, and 2.7$\pm$0.96, respectively. The numbers of vomiting episode before and after octreotide treatment were 3.6/day$\pm$2.5, and 0.4/day$\pm$0.8, respectively. The mean amounts of nasogastric tube drainage before and after octreotide treatment were 975$\pm$1,083 cc/day and 115$\pm$196 cc/day, respectively. Statistically significant reduction in VAS, the number of vomiting episode and the amount of nasogastric tube drainage were observed after octreotide treatment (P<0.05). Conclusion: Administration of octreotide in patients with malignant bowel obstruction, which is uncontrolled by other medication, was effective and safe. In such clinical situations, physicians should consider to add of octreotide for symptomatic control.

Background: Inadequate drainage of traumatic hemothoraces may result in prolonged hospitalization and complication such as empyema, fibrothorax and pleural calcification. This needs to be the placement of a tube thorascostomy which is efficacious in more than 80% of cases. Other cases require surgical treatment. Material and Method: From March 2002 to February 2003, there were 123 patients who was done closed thorascostomy in traumatic hemothorax. 10 patients (group I) were undergone early retained clot evacuation with video assisted thoracoscopic surgery, but 5 patients (group II) who developed a localized hematoma or empyema were operated. Male were more than female and mean average was similar in both group. The most common cause of injury was traffic accidents and frequently combined lesions were a abdomen. Result: Interval from injury and operation, mean operation time, duration of tube drainage and hospital stay in group I were shorter than group II (p<0.05). Operation-related complication and recurrence of fluid collection within follow up period (17.8$\pm$3.8 months) in group I were none, but in group II (21.5$\pm$5.3 months) were 2 cases. Conclusion: Video assisted thoracoscopic surgery can be utilized as an effective and safe method for the removal of retained clotted hemothorax within 7 days.

The oral hygiene of patients admitted to the ICU (Intensive Care Unit) is very important. Critically ill patients are basically immunocompromised ones because of the high risk of infection by various pathogenic bacteria. The mouth is not only the primary site of infection, but also the site of systemic infections. The purpose of this study was to design a mouthpiece type vacuum oral cleaner for the oral care of seriously ill patients. A 3D CAD modeling and flow analysis model were established for a double structure type cleaner and standard tooth model, and their pressure and flow characteristics were analyzed. The pressure inside the oral cleaner was almost constant, but the velocity distribution showed a large difference between the inside and outside of the teeth. The velocity at the center region inside of the teeth was the highest, and the speed decreased as the distance from the center increased. In the analysis of the case where the suction tube was replaced by the drainage tube, the velocity at the center of the outer portion of the teeth was the highest. In order to increase the effectiveness of the oral cleaner, alternating between suction and drainage is proposed, and a design complement to increase the speed of the molar region is required.

Background: Chest tube drainage (CTD) is an indication for the treatment of pneumothorax, hemothroax and is used after a thoracic surgery. But, in the case of incomplete lung expansion, and/or persistent air leak from CTD, medical or surgical thoracoscopy or, if that is unavailable, limited thoracotomy, should be considered. We evaluate the efficacy of bronchoscopic injection of ethanolamine to control the persistent air leak in patients with CTD. Methods: Patients who had persistent or prolonged air leak from CTD were included, consecutively. We directly injected 1.0 mL solution of 5% ethanolamine oleate into a subsegmental or its distal bronchus, where it is a probable air leakage site, 1 to 21 times using an injection needle through a fiberoptic bronchoscope. Results: A total of 15 patients were enrolled; 14 cases of spontaneous pneumothorax [idiopathic 9, chronic obstructive pulmonary disease (COPD) 3, post-tuberculosis 2] and one case of empyema associated with broncho-pleural fistula. Of these, five were patients with persistent air leak from CTD, just after a surgical therapy, wedge resection with plication for blebs or bullae. With an ethanolamine injection therapy, 12 were successful but three (idiopathic, COPD and post-tuberculosis) failed, and were followed by a surgery (2 cases) or pleurodesis (1 case). Some adverse reactions, such as fever, chest pain and increased radiographic opacities occurred transiently, but resolved without any further events. With success, the time from the procedure to discharge was about 3 days (median). Conclusion: Bronchoscopic ethanolamine injection therapy may be partially useful in controlling air leakage, and reducing the hospital stay in patients with persistent air leak from CTD.

Exudative pleural effusion can arise from pneumonia, tuberculosis, cancer, etc. Early drainage is needed for prevention of complications such as pleural fibrosis, thickening, bronchopleural fistulae and decline of lung function. Intrapleural Instillation of fibrinolytic enzymes has been used for 50years as an adjunct in the removal of fibrous material, hematoma and pus from the thoracic cavity. By the local fibrinolytic effect on fibrinous exudates within the pleural space, fibrinolytic agent has improved results of chest tube or pig tail drainage. But there were no controlled randomized studies, so significant controversy exists concerning the efficacy of this therpy, especially tuberculous pleurisy. Furthermore about complication, severe spontaneous bleeding has not been reported with intrapleural urokinase. Intrapleural fibrinolytic enzymes has shows no systemic complication. When it is administrated intravenously, not into intrpleural space, major bleeding is reported about 1-3% of patient, especially they had systemic disease, such as coagulation abnormalities. This case report presents a patient who suffered major hemothorax induced hypovolemic shock following the administration of 100,000 units of urokinase intrapleurally. He was 25-year old male with tuberculosis pleurisy without systemic illness demonstraion.

Background: This study was conducted to determine the efficacy of staple line coverage using a polyglycolic acid patch and fibrin glue without pleural abrasion to prevent recurrent postoperative pneumothorax. Methods: A retrospective analysis was carried out of 116 operations performed between January 2011 and April 2013. During this period, staple lines were covered with a polyglycolic acid patch and fibrin glue in 58 cases (group A), while 58 cases underwent thoracoscopic bullectomy only (group B). Results: The median follow-up period was 33 months (range, 22 to 55 months). The duration of chest tube drainage was shorter in group A (group A $2.7{\pm}1.2day$ vs. group B $3.9{\pm}2.3day$, p=0.001). Prolonged postoperative air leakage occurred more frequently in group B than in group A (43% vs. 19%, p=0.005). The postoperative recurrence rate of pneumothorax was significantly lower in group A (8.6%) than in group B (24.1%) (p=0.043). The total cost of treatment during the follow-up period, including the cost for the treatment of postoperative recurrent pneumothorax, was not significantly different between the two groups (p=0.43). Conclusion: Without pleural abrasion, staple line coverage with a medium-sized polyglycolic acid patch and fibrin glue after thoracoscopic bullectomy for primary spontaneous pneumothorax is a useful technique that can reduce the duration of postoperative pleural drainage and the postoperative recurrence rate of pneumothorax.

Background: Patients undergoing cardiac surgery require postoperative chest drainage. However, the drain is difficult to keep in place in children with congenital heart disease. Since 2015, at Kyungpook National University Hospital, the chest tube is removed on postoperative day 1 in patients who have undergone simple congenital cardiac surgery (i.e., closure of an atrial or ventricular septal defect). In this study, we evaluated the relationship between the duration of drain placement and the likelihood of pericardial effusion after congenital cardiac surgery. Methods: The medical records of patients who underwent closure of an atrial or ventricular septal defect at our hospital between January 2014 and December 2016 were reviewed. In total, 162 patients who received follow-up echocardiography and had information available on postoperative pericardial effusion after the repair procedure were enrolled. Results: Echocardiography was performed at a median of 5 days (range, 4 to 6 days) postoperatively before discharge from the hospital. Pericardial effusion occurred in 21 patients (13.0%), of whom only 3 (1.9%) had moderate or greater pericardial effusion, regardless of the drain duration. All patients improved during outpatient follow-up without invasive management. No patient had severe complications because of pericardial effusion. The duration of drain placement did not affect the incidence of postoperative pericardial effusion (p=0.069). Operative survival was 100%. Conclusion: Based on our study, we recommend removing the drain as soon as its role is complete, generally on postoperative day 1, because early removal does not increase the incidence of pericardial effusion in patients undergoing simple congenital cardiac surgery.

Background: Malignant pleural effusion affects many patients with advanced cancer. When chemotherapy or radiotherapy fails to relieve malignant pleural effusion and related symptoms, drainage and pleurodesis can help. Although surgical talc pleurodesis is the most widely used method, Viscum album, which has been recently used in surgical or bedside procedures, has demonstrated significant results and is as effective as talc. This study aimed to determine the most effective agent and procedure. Methods: Between January 2015 and July 2022, chemical pleurodesis was performed in 137 patients with malignant pleural effusion, using a V. album surgical procedure in 48, a V. album bedside procedure in 55, and a talc surgical procedure in 34 patients. We reviewed patients' clinical responses and disease progression after chemical pleurodesis. Results: The success rate was not significantly different among the V. album surgical procedures (91.7%), V. album bedside procedures (83.6%), and talc surgical procedures (91.2%). However, the total drainage amount and tube insertion duration in both Viscum groups were more effective than those in the talc group. Furthermore, the bedside Viscum group showed significantly lower post-pleurodesis pain scores than the other 2 groups. Conclusion: According to our results, talc and V. album can be considered ideal agents for chemical pleurodesis. However, Viscum pleurodesis showed safer outcomes in terms of ensuring quality of life than talc. Additionally, the bedside Viscum group showed significantly lower pain scores than the other groups. Hence, patients for whom surgical procedures are inappropriate can undergo bedside Viscum pleurodesis without diminishing the therapeutic effect.
