Nutritional support is essential for improving the outcome in critically ill patients. Enteral nutrition possesses advantages over total parenteral nutrition in that it maintains the physiologic barrier function of the gastrointestinal mucosa. Short-term enteral nutrition can be achieved through transnasal feeding tubes. Traditionally, feeding tubes have been placed at bedside in a blind fashion. However, blind tube placement is unreliable as it may result in improper positioning of the tubes. Numerous complications arising from misplacement have been reported in the literature. A number of modalities may be used in order to improve the accuracy and safety of transnasal feeding tube placement. Fluoroscopy is widely accepted for this purpose. Together with the use of water-soluble contrast media and over-the-wire technique, fluoroscopy-guided placement of nasogastric or nasojejunal feeding tubes offers a higher rate of technical success while decreasing procedure time as well as the incidence of procedure-related complications.

Pancreatic cancer has been identified as one of the most common malignant causes of upper gastrointestinal obstruction. Most common sites of obstruction include the pyloric region and second and third portions of the duodenum. If surgical gastrojejunostomy is not a viable option, metallic stent placement may be performed either by transoral or transgastric approach. Transgastric technique is considered to be more invasive and is often employed only in failed attempts to insert a stent using transoral technique. This report presents a 70-year-old patient with pancreatic cancer involving the proximal jejunum. Although this is a rarely described location for stenting, the patient was successfully treated using transgastric technique.

Atherectomy has become a promising treatment option for peripheral artery disease caused by diabetes mellitus or end-stage renal disease. Atherectomy refers to the removal of atheromatous tissue by mechanical method, resulting in an enlarged lumen of the treated blood vessel. Based on this method, the term is limited to the percutaneous minimally invasive approach, and there are currently two types of atherectomy devices available in Korea. The increased prevalence of atherectomy has led to the concept of “vascular preparation” and a new treatment concept of “leave nothing behind.” Various studies have proven the safety and effectiveness of atherectomy; however, there are some limitations. We need to remain focused on patient selection and subsequent large-scale research.

Cystic sebaceous adenomas are rare neoplasms that can arise in salivary glands. Among the salivary glands, the most commonly reported location is the parotid gland where it must be differentiated from other intraparotid masses. Unfortunately, its imaging features are not well-known as a result of its rarity. We report a case of cystic sebaceous adenoma that manifested as a gradually enlarging mass within the parotid gland of a 60-year-old man.

BACKGROUND/AIMS: To investigate sequential changes in laboratory markers after radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) and the relationship of these changes to the severity of the underlying liver disease. METHODS: This retrospective analysis included 65 patients (44 males, 21 females) who underwent RFA of HCC. Hematologic and biochemical markers were assessed at the pre-RFA period and 1 day, 2-3 days, and 1-2 weeks after RFA. We classified the subjects into two groups: Child-Pugh A (n=41) and Child-Pugh B (n=24). The ablative margin volume (AMV) of each patient was measured. We analyzed the changes in laboratory profiles from the baseline, and investigated whether these laboratory changes were correlated with the AMV and the Child-Pugh classification. RESULTS: Most of the laboratory values peaked at 2-3 days after RFA. AMV was significantly correlated with changes in WBC count, hemoglobin level, and serum total bilirubin level (Pearson's correlation coefficient, 0.324-0.453; P<0.05). The alanine aminotransferase (ALT) level varied significantly over time (P=0.023). CONCLUSIONS: Most of the measured laboratory markers changed from baseline, peaking at 2-3 days. The ALT level was the only parameter for which there was a significant difference after RFA between Child-Pugh A and B patients: it increased significantly more in the Child-Pugh A patients.

Chyle leakage (CL) due to lymphatic injuries is one of the rare complications that can develop after thyroidectomy. There are few studies on lymphatic embolization performed in case of CL after thyroid surgery. We report two cases of CL after thyroid surgery that were effectively treated by thoracic duct embolization. The patients had previously undergone total thyroidectomy with central compartment neck dissection with or without modified radical neck dissection. The amount of drainage from the operative site was ＞1000 mL per day in one patient and ＞500 mL per day in the other. In both cases, CL stopped after the thoracic duct embolization. Thoracic duct embolization seems to be an effective and important treatment option for CL after thyroid surgery.

Multilocular thymic cyst (MTC) has been reported to develop in concert with various mediastinal neoplasms that have intrinsic inflammatory components, such as thymoma, thymic carcinoma, Hodgkin's disease, and seminoma. However, development of mediastinal teratoma without intrinsic inflammation in association with MTC has rarely been reported. Here, we report the findings of a case of MTC associated with mediastinal mature cystic teratoma on computed tomography (CT) with CT-histopathologic correlation.
