BACKGROUND: Midazolam has been reported to have a spinally mediated antinociceptive effect. In this randomized, double-blind study, we evaluated whether a small dose of midazolam added to fentanyl-ropivacaine mixture for PCEA (patient controlled epidural analgesia) improves epidural analgesia in patients underwent elective subtotal gastrectomy. METHODS: Forty five patients, ASA physical status I and II, undergoing subtotal gastrectomy were randomly allocated to receive 0.2% ropivacaine mixed with fentanyl 4microg/ml or 0.2% ropivacaine mixed with fentanyl 4microg/ml and midazolam 0.2 mg/ml. The infusion rate was set to deliver 4 ml/hr of the study solution, with a bolus of 2 ml per demand and a 20 minutes lockout time. RESULTS: Infused volume (P < 0.05) and VAS scores (P < 0.05) was significantly lower in the patients receiving midazolam. However, there were no differences in requiring rescue analgesics, PONV (postoperative nausea and vomiting), sedation scores, urinary retention, and pruritus between groups. CONCLUSIONS: Small dose of midazolam could augment analgesia without adverse effects when added to thoracic epidural infusion of fentanyl and ropivacaine.

Traditionally, tissue biopsies of kidney lesions are usually performed with CT or percutaneous ultrasound guidance, but biopsies using EUS have rarely been reported. In this report, we describe a case of renal cell carcinoma (RCC) diagnosed using EUS-guided fine-needle aspiration biopsy. A 75-year-old woman taking aspirin due to stable angina continued to exhibit weight loss and anemia and visited the gastroenterology department. No bleeding was observed on upper and lower gastrointestinal endoscopy. A contrast-enhanced mass was observed in the left kidney, accompanied by 8.9×10.8 cm-sized necrosis suggesting RCC on abdominal CT. Chest CT showed masses in both lungs. We planned to administer targeted therapy after pathological confirmation using EUS. Aspirin was continued, and we performed fine-needle biopsy using a 22-gauge needle three times. No adverse events were observed after the procedure. Pathological examination confirmed RCC, clear cell type, and the patient is currently undergoing treatment with sunitinib. EUS-guided fine-needle aspiration biopsy is safe for liver, pancreatic, or other tumors accessible from the upper gastrointestinal tract. This technique shows fewer adverse events. To the best of our knowledge, there have been no other reports on EUS-guided fine-needle aspiration biopsy to identify RCC in Korea.
