Breakdown of the normal protective function of the larynx, either through primary or neurologic cause, leads to chronic aspiration, recurrent pneumonitis and possibly death. Lindemann`s tracheoesophageal diversion has three main advantages; first, it eliminates intractable aspiration in all patients who underwent the procedure, second, it preserves larynx, and third, if the underlying neurologic condition is recorved, the procedure can be reversed. We had performed tracheoesophageal diversion in two cases of intractable aspiration pneumonia patients. The postoperative courses were uneventful and they were receiving oral alimentation on the 22th and 9th postoperative days respectively, and could be discharged on 43th and 20th postoperative days respectively.

Purpose: To evaluate the drainage effect of silk suture following aspiration of the bursa as an early treatment of chronic lateral malleolar bursitis. Materials and Methods: Thirteen cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 16.4 months. The average symptom duration before introduction into this study was 7.8 weeks. With an aseptic technique, the aspiration of the bursa was done with 18G needle and syringe and then the insertion of silk suture through the aspiration needle was performed. The amount of drainage was identified two or three times in a week and stitch out was done at the cessation of drainage. Over one year follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Results: Redness around the insertion site of silk suture was found in all cases, but there was no development of active infection or recurrence. The average duration of treatment is 10.4 days. Conclusion: The drainage with silk suture following aspiration of the bursa is less invasive and very effective method in the early treatment of chronic lateral malleolar bursitis.

The purpose of this study was to evaluate the drainage effect of silk suture following aspiration of the bursa as an early treatment of chronic olecranon bursitis. Eleven cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 17.5 months. The average symptom duration was 1.8 months. With an aseptic technique, the aspiration of the bursa was done with 18gauge needle and syringe and then the insertion of silk suture through the aspiration needle was performed. The amount of drainage was regularly checked $2{\sim}3$ days interval and stitch out was done at the cessation of drainage. At the follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Redness around the insertion site of silk suture was found in all cases, but there was no active infection or recurrence. The results were satisfactory in all cases and the average time for recovery was 10.5 days. The drainage with silk suture following aspiration of the bursa is less invasive and very effective method in the early treatment of chronic olecranon bursitis.

Thoracic paravertebral block is performed for the treatment of patients with chronic pain, such as complex regional pain syndrome (CRPS) and post-herpetic neuralgia. Thoracic paravertebral block can result in iatrogenic pneumothorax. Because pneumothorax can develop into medical emergencies and needle aspiration or chest tube placement may be needed, early diagnosis is very important. Recently, thoracic ultrasonography has begun to be used to diagnose pneumothorax. In addition, ultrasound-guided aspiration can be an accurate and safe technique for treatment of pneumothorax, as the needle position can be followed in real time. We report a case of iatrogenic pneumothorax following thoracic paravertebral block for the treatment of chronic pain due to CRPS, treated successfully by ultrasound-guided aspiration.

BACKGROUND： Aspiration is defined as the laryngeal penetration of secretions below the level of the true vocal cords. Aspiration can result in life-threatening complications, such as bronchospasm, airway obstruction, pneumonia, pulmonary abscess, sepsis, and death. The patient with high vagal palsy had significant aspiration and dysphagia OBJECTIVE： To formulate a step-by-step management paradign for the patients with high vagal palsy MATERIALS AND METHODS : The medical records of 23 patients who were diagnosed as high vagal palsy from September, 1995 to April, 1998 in Seoul National University Hospital were reviewed retrospectively. Eleven patients were managed conservatively and 12 patients were operated to treat chronic aspiration. RESULTS : The main etiologies of high vagal palsy were mass lesions of the skull base such as neurogenic tumor, pseudotumor, meningioma or nasopharyngeal carcinoma. Aspiration and dysphagia improved in 7 out of 11 patients who were managed conservatively after 2.2 months on the average. The patients who were refractory to the conservative management underwent surgery and showed improvement in 10 out of 12 patients. The employed surgical modalities were vocal cord medialization combined with cricopharyngeal myotomy in 7 patients, laryngotracheal separation in 3 patients and arytenoid adduction only in 2 patients. Two patients still had gastrostomy tube due to the persistent symptoms. Two patients had improved after surgery, but died of underlying disease. CONCLUSION : The patients with high vagal palsy are recommended to be managed conservatively for the first 2 months. If aspiration and dysphagia are persisting after conservative management, vocal cord medialization combined with or without cricopharyngeal myotomy should be considered. If failed, laryngotracheal separation or gastrostomy will be the next option based on the control of the oropharyngeal secretion.

Background and Objectives: Since intractable aspiration in patients with impaired protective function of the larynx often results in multiple episode of aspiration pneumonia, repeated hospitalizations and expensive nursing care. The authors reported the preliminary results of laryngotracheal separation(LTS) in patient with chronic intractable aspiration. The purpose of this study was to report the follow up results of patient outcome with the LTS. Materials and Methods: A retrospective review of 15 patients who underwent LTS between 1996 and 2006 was conducted. Ages ranged from 3 to 72 years. Results: Eight patients had morbid aspiration as a consequence of acquired neurologic injuries and seven patients with congenital neurologic injuries. Two patients had a postoperative fistula, which was well controlled with local wound care. Following LTS, aspiration was effectively controlled in all patients and eight were able to tolerate a regular diet. Conclusion: LTS is a low-risk, successful, definitive procedure which decreases the potential for aspiration, pulmonary complications, duration of hospitalizations and increases quality of life, especially in patent with irreversible upper airway dysfunction and poor speech potential.

Pancreatic pseudocyst is one of the most common pancreatic mass lesions developed following acute or chronic pancreatitis. Two dogs were presented with nonspecific clinical signs such as abdominal pain, vomiting and depression and diagnosed as pancreatic pseudocysts through percutaneous ultrasound-guided aspiration. Pancreatic pseudocyst may contain pancreatic juice, so leads the deteriorate state of patient through pertinent inflammation and autodigestion of pancreas. In this study, the clinical signs and pancreatic lesion were improved after aspiration. Percutaneous ultrasound-guided aspiration can provide the diagnostic information through cytology and lipase and amylase concentration, and be selected as the first choice for treatment.

Objective : The aim of this study was to investigate risk factor, precaution and treatment of aspirated foreign body during dental procedure. Material and Methods : Twenty cases of accidental aspiration of the foreign body, which removed by bronchoscopy at the Asan Medical Center between 2008 and 2012, were analyzed retrospectively. Results : Ten cases of accidental aspiration were occurred during dental procedure. Symtoms include cough(65%), dyspnea(50%), sputum(25%) and wheezing(25%). The most common location of foreign body was right bronchial tree(50%), left bronchial tree(45%) and carina(5%). Patients risk factors were chronic obstructive pulmonary disease, lung cancer, pulmonary tuberculosis, esophageal cancer and vegetative state. Conclusion : Accidental aspiration or swallowing of dental instrument or material is not uncommon accidents in dental practice. Most foreign bodies enter into gastrointestinal tract spontaneously. But aspiration into broncho-trachea can be more serious events and must be treated as an emergency situation. Prompt emergency treatment and removal of the foreign body is necessary to avoid complication. Dentists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental procedures.
