We present a modified method for the treatment of brain abscess. The double lumen extraventricular drainage (EVD) catheter which was developed for the intracerebral hematoma management, was applied for the treatment of brain abscess drainage. We placed the double lumen EVD catheter into the abscess cavity by free-hand technique and irrigated the abscess cavity continuously with antibiotics solution for 7 days. Simultaneous intravenous antibiotics was administered for 4 weeks. The continuous irrigation with double lumen catheter was found to be safe and effective treatment modality in the brain abscess.

The use of double lumen catheters as a means of hemodialysis access is commonly accompanied with the use of gentamicin as an antibiotic lock. Other antibiotics and anticoagulants are often added to increase the efficacy of gentamicin in order to reduce catheter-related infection and to prevent biofilm formation. This review aimed to evaluate the following: 1) the use of gentamicin in eliminating catheter-related infection and reducing biofilm formation in hemodialysis catheters, 2) the efficacy of additional antibiotics in combination with gentamicin, and 3) the effect of additional anticoagulants to complement the efficacy of gentamicin as the main prophylactic antibiotic lock. We sorted through data from 242 PubMed and ScienceDirect studies, which were then short-listed to 33 studies. Next, they were grouped, extracted, and analyzed qualitatively to fulfil the objectives of this review. Consequently, the use of a gentamicin-lock solution was shown to reduce the incidence of bacteremia; however, it was not strong enough to inhibit the growth of infectious microbes and formation of biofilms. Several bacteria, such as Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, and Klebsiella pneumoniae, have been reported as infectious agents. Combination with other antibiotics also provided no effect in reducing bacterial growth and biofilm formation in catheters. Furthermore, the additional anticoagulants (trisodium citrate and EDTA) were reported to be effective in enhancing the efficacy of gentamicin in avoiding catheter-related infection, bacterial growth, and biofilm formation; thus, the use of gentamicin can be rationalized.

The number of cases of extracorporeal membrane oxygenation (ECMO) has rapidly increased all over Korea since the introduction of peripheral cannulation catheters. However, the application of ECMO to children has been limited due to the shortage of pediatric equipment and difficulty in maintaining an ECMO system with peripheral cannulation. For this reason, there have been only few reports of pediatric ECMO in Korea, and most of them pertained to the veno-arterial type ECMO for supporting the cardiac system in postcardiotomy patients. We report here on the successfully performing veno-venous ECMO, with using a double lumen percutaneous catheter, in a child with acute respiratory distress syndrome.

Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) is widely performed not only as an alternative to transpapillary biliary drainage, but also as primary drainage for malignant biliary obstruction. For anatomical reasons, this technique carries an unavoidable risk of mispuncturing intrahepatic vessels. We report a technique for troubleshooting EUS-guided portal vein coiling to prevent bleeding from the intrahepatic portal vein after mispuncture during interventional EUS. EUS-HGS was planned for a 59-year-old male patient with unresectable pancreatic cancer. The dilated bile duct (lumen diameter, 2.8 mm) was punctured with a 19-gauge needle, and a guidewire was inserted. After bougie dilation, the guidewire was found to be inside the intrahepatic portal vein. Embolizing coils were placed to prevent bleeding. Embolization coils were successfully inserted under stabilization of the catheter using a double-lumen cannula with a guidewire. Following these procedures, the patient was asymptomatic. Computed tomography performed the next day revealed no complications.

Background: A major ingredient of green tea is epigallocatechin-3-gallate (EGCG), and this is known to have many beneficial effects for cancer prevention and also on the cardiovascular system and neurodegenerative diseases through its anti-oxidant, anti-angiogenic, anti-inflammatory, lipid-lowering and neuroprotective properties. Its actions on nociception and the spinal nervous system have been examined in only a few studies, and in these studies EGCG showed an antinociceptive effect on inflammatory and neuropathic pain, and a neuroprotective effect in motor neuron disease. This study was performed to investigate the effect of EGCG on acute thermal pain and the development of morphine tolerance at the spinal level. Methods: The experimental subjects were male Sprague-Dawley rats and the Hot-Box test was employed. A single or double-lumen intrathecal catheter was implanted at the lumbar enlargement for drug administration. An osmotic pump was used to infuse morphine for 7 days for induction of morphine tolerance. EGCG was injected repeatedly for 7 days at twice a day through the intrathecal catheter. Results: Intrathecal EGCG increased the paw withdrawal latency (PWL) after repeated administration for 7 days at twice a day, but this did not happen with administering on single bolus injection of EGCG. In addition, the antinociceptive effect of intrathecal morphine was not affected by co-administration with EGCG. A continuous 7-day infusion of morphine caused a significant decrease of the PWL in the control group (M + S, morphine plus saline). In contrast, intrathecal EGCG injection over 7 days blocked the decrease of the PWL in the experiment group (M + E, morphine plus EGCG). Conclusions: Intrathecal ECGC produced a weak antinociceptive effect for acute thermal pain, but it did not change the morphine's analgesic effect. However, the development of antinociceptive tolerance to morphine was attenuated by administering intrathecal EGCG.

Apatient, 51 years old woman, had suffered form headache and decrease of visual acuity. She had $3{\times}3cm$ sized giant aneurysm originated in cavernous and clinoid portion of left ICA(C4,C5) in the cerebral angiography. Before craniotomy, left CCA was exposed and 6F double lumen catheter was inserted in left ICA through the sheath. Pre-operative angiography was done. balloon catheter was positioned at the petrous portion of ICA. Eyebrow approach was done and giant aneurysm was exposed. The proximal blood flow was controlled with balloon dilatation and suction and decompression was tried, then multiple clips were applied. The loss of distal blood flow under intra-operative angiography was notified after clipping. The position of clips were repositioned to preserve blood flow & the rich flow was confirmed at distal part of clipping. In the post-operative cerebral angiography, the same finding was shown.

Background/Aims: This study aimed to clarify the efficacy and safety of pancreatic duct lavage cytology combined with a cell-block method (PLC-CB) for possible pancreatic ductal adenocarcinomas (PDACs). Methods: This study included 41 patients with suspected PDACs who underwent PLC-CB mainly because they were unfit for undergoing endoscopic ultrasonography-guided fine needle aspiration. A 6-Fr double lumen catheter was mainly used to perform PLC-CB. Final diagnoses were obtained from the findings of resected specimens or clinical outcomes during surveillance after PLC-CB. Results: Histocytological evaluations using PLC-CB were performed in 87.8% (36/41) of the patients. For 31 of the 36 patients, final diagnoses (invasive PDAC, 12; pancreatic carcinoma in situ, 5; benignancy, 14) were made, and the remaining five patients were excluded due to lack of surveillance periods after PLC-CB. For 31 patients, the sensitivity, specificity, and accuracy of PLC-CB for detecting malignancy were 94.1%, 100%, and 96.8%, respectively. In addition, they were 87.5%, 100%, and 94.1%, respectively, in 17 patients without pancreatic masses detectable using endoscopic ultrasonography. Four patients developed postprocedural pancreatitis, which improved with conservative therapy. Conclusions: PLC-CB has an excellent ability to detect malignancies in patients with possible PDACs, including pancreatic carcinoma in situ.
