Spontaneous Common Bile Duct Perforation Treated with Placement of Metal Stent / 대한췌담도학회지

Perforation of the biliary tree mostly results from injury to the bile duct during surgery or procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and spontaneous bile duct perforation is rare in adults. As the clinical picture varies, early diagnosis and treatment of spontaneous biliary peritonitis is difficult. A 52-year-old male patient presented with abdominal pain and intractable ascites. He already experienced severe abdominal pain 2 months ago and underwent percutaneous pigtail drainage for the ascites at nearby hospital. ERCP showed large filling defect with leakage of contrast media from the mid common bile duct (CBD) into the peritoneal cavity. We performed endoscopic sphincterotomy and extracted CBD stones with basket and balloon catheter. Then fully covered self expandable metal stent was placed in CBD. After the procedure, the symptom was improved and the amount of pigtail drainage from abdominal cavity was dramatically decreased. 6 weeks later, removing the metal stent, there was no more leakage of contrast media into peritoneal cavity. We report a very rare case of spontaneous bile leakage which was successfully managed with placement of metal stent.

Single Nodular Pulmonary Amyloidosis: Case Report / 결핵및호흡기질환

Amyloidosis is defined as the presence of extra-cellular deposits of an insoluble fibrillar protein, amyloid. The pulmonary involvement of amyloidosis is usually classified as tracheobronchial, parenchymal nodular, or diffuse alveolar septal. A single nodular lesion can mimic various conditions, including malignancy, pulmonary tuberculosis, and fungal infection. To date, only one case of nodular pulmonary amyloidosis has been reported in Korea, a case involving multiple nodular lesions. Here, we report and discuss the case of a patient having single nodular amyloidosis.

Efficacy and Safety of Radiofrequency Ablation Performed by an Endocrinologist for Benign Thyroid Nodules

BACKGROUND AND OBJECTIVES: Radiofrequency ablation has recently been used for the treatment of benign thyroid nodules, with outstanding results. However, in most studies, the procedure was usually performed by a radiologist or surgeon. This study aimed to evaluate the efficacy and safety of radiofrequency ablation for nodules >2 cm performed by an endocrinologist with several years of experience performing fine-needle aspiration cytology. MATERIALS AND METHODS: This study was a cross-sectional analysis of 111 patients who received radiofrequency ablation between April 2010 and July 2013. A total of 73 patients with 75 nodules >2 cm in diameter with at least 6 months of follow-up examinations were included. RESULTS: The mean follow-up period was 11.5 months. The mean nodule volume decreased from 17.0+/-15.3 mL preoperatively to 6.0+/-8.5 mL postoperatively, with a mean volume reduction of 69.7%. There were no major complications, and only 1 patient (1.3%) presented with a minor complication (hemorrhaging of the thyroid parenchyma). CONCLUSION: Radiofrequency ablation is a safe method for reducing benign thyroid nodules, and is not associated with any major complications.

A Case of Chronic Diarrhea after Neurolytic Celiac Plexus Block: A case report / 대한통증학회지

A neurolytic celiac plexus block produces long-lasting pain relief in upper abdominal cancer patients. Unwanted side effects such as local pain, hypotension, and diarrhea are common but the durations of these side effects are usually transient. Chronic diarrhea induced by a neurolytic celiac plexus block is rarely reported and is considered to be an autonomic neuropathy due to sympathetic denervation. A 73-year-old Klatskin tumor patient developed chronic diarrhea after a neurolytic celiac plexus block and the diarrhea was sustained for 3 months despite the use of conventional antidiarrheal treatments. We report a case of chronic diarrhea that was induced by a neurolytic celiac plexus block.

Comparison of Bupivacaine and Normal Saline for Epidural Top-up on Sensory Blockade Level during Combined Spinal Epidural Anesthesia / 대한마취과학회지

BACKGROUND: An increase in the maximum level of sensory blockade by epidural 'top-up' in combined spinal epidural anesthesia may be explained by two mechanisms; a volume effect, compressing the dural sac, and a local anesthetic effect. This study was undertaken to investigate the relative importance of these factors. METHODS: Eighty patients about to undergo lower limb surgery under combined spinal epidural anesthesia were randomly assigned to four groups. Using the needle-through-needle technique, all patients received a subarachnoid injection of 8 mg of heavy bupivacaine through an epidural catheter. At 30 minutes after subarachnoid injection, an epidural top-up was given according to a randomization code. Experimental groups received 10 ml of saline, 10 ml of bupivacaine 0.25%, or 10 ml of bupivacaine 0.5%. The control group received no epidural top-up. The level of sensory blockade was checked by using the pinprick test at 5, 10, 15, 20, 25 and 30 minutes after subarachnoid injection, and at 5, 10, 15, 20, 25 and 30 minutes after epidural top-up. Blood pressure, heart rate and the incidence of side effects such as hypotension, bradycardia, nausea, and high block were analyzed. RESULTS: There was no significant difference in maximum level of sensory block among the 10 ml saline, 10 ml bupivacaine 0.25% or 10 ml bupivacaine 0.5% treated groups during epidural phase. Although blood pressure and heart rate were decreased, there were no differences among experimental groups during epidural phase. The most common side effect during combined spinal epidural anesthesia was hypotension. The incidence of bradycardia and high sensory block (above T4 dermatome level) was similar among the groups. CONCLUSIONS: After the maximum level of sensory blockade due to subarachnoid injection has been established, an epidural top-up with 10 ml of saline or 10 ml of either 0.25% or 0.5% bupivacaine did not significantly increase the level of subarachnoid block in patients with lower extremity surgery. The author concludes the there were no differences among groups with regard to the volume effect and local anesthetic effect in terms of the sensory blockade level during the epidural phase. However, blood pressure and heart rate in the epidural top-up groups reduced with operation time.
