Epidural adhesiolysis is a convenient and safe method for the management of back pain. However, we experienced a case where a patient developed sensory change to S2 area after epidural adhesiolysis. Male patient, 43 years old, was admitted to our pain clinic for epidural adhesiolysis for back pain. Patient was experiencing pain radiating to left thigh, and sensory change and motor disturbance to the S1 area. Patient's symptoms and signs were much improved on the first day of epidural adhesiolysis. Patient, however, complained of numbness of perineal and S2 areas after the next day of injections. We postulated the cause of this complication was due to: compression of nerve root by the large volume of injectate and hematoma, and the side effect of local anesthetic, hypertonic saline and steroid.

Horner's syndrome is a well-recognized complication of regional analgesia of neck and shoulder region, and not often a complication of lumbar or low thoracic epidural block. Recently we experienced right Horner's syndrome accompanying paralysis of right upper extremity following lumbar epidural block in for an obstetric patient. Epidurography and MRI was performed to clarify the cause of unilateral high epidural block and cervical sympathetic block. Radiologic study demonstrated a loop formation of the epidural catheter and tip of catheter was located in right anterior epidural spaced(L1-2). The initial epidurogram revealed unilateral spreading of dye in the cervical region in right epidural space. A second epidurogram, 10 minutes following, showed dye filling in left epidural space, however spread of dye in left side was limited to lumbar and low thoracic region. We concluded the most probable cause of this unilateral high epidural block was due to misplacement of the catheter into the anterior epidural space.

Dentally disabled person means one who have difficulty in cooperating voluntarily with a dentist for routine dental care. Seoul National University Dental Hospital (SNUDH) Dental Clinic for Disabled has worked for them under outpatient anesthesia concept. The aim of this study was to determine the anesthetic characteristics of the patients attending for dental treatment at SNUDH Dental Clinic for Disabled in order to establish better future treatment plans. The data were drawn from the patients who visited SNUDH Dental Clinic for Disabled from January 1999 to October 2002. Total 93 dental treatments for 83 patients were enrolled in this study. Most patients had mental retardation and the conservative treatments were carried out under general anesthesia. Thiopental and vecuronium were mostly used for induction agent and neuromuscular blocker, respectively. Enflurane, with oxygen and nitrous oxide, was mostly used to maintain the anesthesia. Mean total anesthetic time was $164.4{\pm}57.2$ minutes and mean duration at the post-anesthetic care unit was $106.2{\pm}50.5$ min. Serious postoperative complications were not observed. These results showed our successful anesthetic outcomes without any severe side effect or complication and the needs of more outpatient centers for dental care for disabled.

Purpose: Several methods of the nipple reduction have been reported. However, the methods described previously are difficult or have some demerits. This study proposes a simple technique for reduction of the nipple height as well as diameter. Methods: The purposed nipple height is marked. A pentahedral design of excision was marked around the nipple. Local anesthetic solution was infiltrated and a 4 - 0 Nylon traction suture was applied at the nipple apex. Excision of the nipple inside both two triangles and a rectangle was made. Remaining two flaps were approximated using 5 - 0 Nylon simple interrupted sutures. However, a part of wound closure was not done in the central area of the nipple. Results: 83 patients(166 nipples) underwent this procedure from December 1999 to December 2008. Follow up ranged from 6 months to 2 years with a mean of 10 months. 78 patients were female and 5 patients were male. No major complication occurred and remaining scars were very inconspicuous. Conclusion: This simple technique has the advantage of nipple reduction in both height and diameter, and provides good aesthetic outcomes.

The authors report the result achieved in the treatment of trigeminal neuralgia patient, especially V2 involved patient, using radiofrequency (RF) thermocoagulation of Gasserian ganglion. A 62-year old female patient had severe burning pain on right cheek usually initiating from upper molar teeth area for 10 years. She was treated with microvascular decompression operation 10 years ago. However, there was no pain relief by operation. She wanted non-surgical treatment. Therefore, we recommended RF thermocoagulation therapy. After 2 times of RF thermocoagulation, there was excellent pain relief without complications. And, for 6months follow-up, there were no pain, and no evidences of complication and recurrence.

The patients with tracheal stenosis have become more increasing in recent due to the increased use of tracheostomy and assisted ventilation Anesthetic management during tracheal reconstruction is a concern to the anesthetist and the surgeon, who must share the airway as a operation field and at the same time provide good gas exchange. Multiple technique such as the tube ventilation system or C \ulcornerP bypass method have been recommended to achieve this goals. However, these methods have disadvantages of poor surgical exposure and hemorrhagic complication from using C \ulcornerP bypass The technique for HFJV was first described for bronchoscopy, and it involves positive-pressure breathing with high flow[40 \ulcorner60L/min] of oxygen This flow is directed to a semirigid catheter inserted in the endotracheal tube and the tracheal reconstruction can be done without interruption. From Dec. 1986 to July 1990 we have experienced 6 patients of tracheal stenosis necessitating circumferential resection and end to end anastomosis; 5 patients with tracheal stenosis following cuffed tracheostomy or intubation, a patient with tracheal stenosis due to invasive thyroid cancer. The specific advantages during tracheal reconstruction are unobstructed field during surgical reconstruction and good gas exchange through the procedure.

Resection and reconstruction of distal trachea or carina have posed tremendous technical challenges for surgeons. Successful outcome depends on thorough preoperative evaluation, careful anesthetic management,strict attention of surgical technique and postoperative care. We report a successful case of revision of tracheal stenosis using femoro-femoral bypass on a 13~year-old boy. The patient complained severe dyspnea about I month following right sleeve pneumonectomy. Preoperative CT scan and intraoperative bronchoscopy showed pin-point tracheal stenosis at a tracheo-bronchial anastomosis site about 1.2cm in length.At operation the lesion was severely adhesed and the lumen was nearly obstructed. The stenotic segment was resected and direct end-to-end anastomosis was done under femoro-femoral bypass for adequate oxygenation. The patient was discharged at postop. 16 days without specific complications and has continued to do well.

Recently, continuous epidural catheter insertion is usually employed in operation and chronic pain control. Delayed migration of an extradural catheter into subdural space or subarachnoid space is a rare but life threatening complication of continuous epidural catheter insertion, especially with out patients. The symptoms may include lower extremity weakness, hypotension, drowsy and respiratory depression. We experienced two cases of lower extremity paralysis due to delayed migration into subdural or subarachnoid spaces at our pain clinic. The tecnical procedures for continuous epidural catheterization went smoothly without any complications. However, clinical signs of lower extremity paralysis and sensory loss developed gradually, about 2 hours and 30 minutes after the continuous epidural injection. Two cases were confirmed by subdurogram and myelogram.

Cervical epidural block can be useful in the management of acute and chronic pain of the head, neck, shoulder, and arm, for selected patients. In spite of the widespread use of cervical epidural blocks for pain, there is limited published data on the specific technique and complications regarding the procedure. High levels of epidural block do not appear to be associated with clinically significant circulatory or ventilatory changes unless the concentrations of local anesthetics used are great enough to produce paralysis of intercostal and phrenic nerves. However, high level of epidural block is associated with sympathetic block which may affect responses of circulatory and ventilatory systems. Accordingly, the possibility of major complications of cervical epidural block must be borne in mind. We experienced two cases of respiratory arrest during cervical epidural block with bupivacaine. This is a report regarding complications of cervical epidural block.

The first successful transthoracic esophagectomy and intrathoracic esophago- gastric anastomosis reported in 1938. Stomach, small intestine, and colon as well as free revascularized grafts have been substituted for excised esophagus. During the past 60 years, there have been substantial advances in preoperative assessment, nutritional support, anesthetic and operative techniques, and postoperative care of patients undergoing esophageal resection and reconstruction. However the hospital mortality and morbidity of esophageal resection and reconstruction is still high and disruption of an intrathoracic esophagogastric anastomosis continues to be the most dreaded complication of esophageal surgery, And the choice of the conduit is still controversial. In this paper, I would like to review the current surgical options available to patients who require esophageal resection and reconstruction as well as the advantages and disadvantages of each technique.
