4.Percutaneous placement of H-configured triple biliary and enteral stents through a single access: A solution for complex bilio-enteric obstruction
Gastrointestinal Intervention 2018;7(1):36-39
A 75-year-old male with recurrent pancreatic adenocarcinoma after a previous Whipple's procedure presented with jaundice. The local advancement of the tumor caused obstructions of the common bile duct, intrahepatic bile duct hilum, and small bowel. Endoscopic stent insertion was precluded by the Roux-en-Y reconstruction. A successful transhepatic percutaneous single-access stenting of the whole biliary tree and intestine was achieved by H-configured triple stenting by combining T-configured dual stent placement in the biliary system with a duodenal stent insertion across the bottom of the anastomosis after looping a wire in the afferent limb. The ‘H-configured’ stents remained patent for 10 months without major or minor complications. This technique adds a new minimal-invasive and effective palliative option for patients with obstruction of a bilio-enteric anastomosis inaccessible to endoscopy.

Radiofrequency ablation (RFA) is a well-known, effective, and safe method for treating benign thyroid nodules and recurrent thyroid cancers. Thyroid-dedicated devices and basic techniques for thyroid RFA were introduced by the Korean Society of Thyroid Radiology (KSThR) in 2012. Thyroid RFA has now been adopted worldwide, with subsequent advances in devices and techniques. To optimize the treatment efficacy and patient safety, understanding the basic and advanced RFA techniques and selecting the optimal treatment strategy are critical. The goal of this review is to therefore provide updates and analysis of current devices and advanced techniques for RFA treatment of benign thyroid nodules and recurrent thyroid cancers.

Gastrointestinal Intervention 2017;6(3):183-186
Biliary stricture formation is a known complication of hepatic surgery in cases of adult living donor liver transplant. In our case, successful percutaneous placement of a hepatico-gastric stent was performed for the drainage of an isolated bile duct after right liver transplant with Roux-en-Y biliary anastomosis in a 42-year-old male. The patient initially presented with cholangitis and a percutaneous transhepatic cholangiogram revealed an isolated stricture of the posterior bile duct. Multiple attempts at regaining continuity of the isolated bile duct with the jejunum were unsuccessful. Thus a tract was created via a percutaneous transhepatic and transluminal approach between the isolated duct and the stomach using a covered stent. The patient had no complications at 18-month follow-up.

7.Updates on Percutaneous Radiologic Gastrostomy/Gastrojejunostomy and Jejunostomy.
Gut and Liver 2010;4(Suppl 1):S25-S31
Gastrostomy placement for nutritional support for patients with inadequate oral intake has been attempted using surgical, endoscopic, and, more recently, percutaneous radiologically guided methods. Surgical gastrostomy has been superseded by both endoscopic and radiologic gastrostomy. We describe herein the indications, contraindications, patient preparations, techniques, complications, and aftercare with regard to radiologic gastrostomy. In addition, we discuss the available tube types and their perceived advantages. There remain some controversies regarding gastropexy performance and primary percutaneous gastrojejunostomy. Percutaneous jejunostomy is indicated for patients whose stomach is inaccessible for gastrostomy placement or for those who have had a previous gastrectomy.

OBJECTIVE: The aim of this study was to determine the efficacy of the use of an ultrasound-guided fine-needle aspiration biopsy (US-FNAB) to diagnose thyroid nodules smaller than 5 mm in the maximum diameter and to evaluate pathological findings of small thyroid malignancies. MATERIALS AND METHODS: From May 2007 to April 2008, we evaluated the findings of US-FNABs of small thyroid nodules less than 5 mm in the maximum diameter. The cytopathological findings were retrospectively reviewed and the diagnostic performance of the use of an US-FNAB was examined in all patients. RESULTS: Of 201 small thyroid nodules in 180 patients, there were 162 adequate specimens (81%). Among 180 patients, 75 patients underwent thyroid surgery and 50 malignant and 33 benign nodules were identified based on a pathological examination. All small malignant thyroid nodules were identified as papillary thyroid microcarcinomas (PTMCs). There were 34 (55%) true positive, 0 (0%) false positive, 23 (37%) true negative and five (8%) false negative results for malignancy after performing a first US-FNAB in 62 surgically confirmed nodules. The sensitivity (87%), specificity (100%), positive predictive value (100%), negative predictive value (82%), accuracy (92%), false positive rate (0%) and false negative rate (8%) for an US-FNAB were determined. In 23 patients with a primary PTMC, capsular invasion (9%, 2 of 23), a perithyroidal lymph node metastasis (30%, 7 of 23), the rate of multifocality (9%, 2 of 23) and bilaterality (4%, 1 of 23) were also determined. CONCLUSION: An US-FNAB of thyroid nodules smaller than 5 mm in the maximum diameter is an effective diagnostic procedure.

Spontaneous and post-traumatic renal intracystic hemorrhages are extremely rare, but are a potential danger to patients with cystic kidney disease. We report two cases of post-traumatic intracystic massive hemorrhage in renal cysts. One patient was a 27-year-old male who presented with left flank pain and gross hematuria after slipping on the stairs 2 days previously. The other patient was a 58-year-old male who presented with back pain due to an accident. The circulatory states of the two patients were deteriorated and renal intracystic hemorrhages were detected on computed tomography. One patient underwent a simple nephrectomy and the other patient was treated with arterial embolization. We present two cases of renal intracystic hemorrhage, emphasizing early diagnosis and the treatment of choice.

PURPOSE: We wanted to describe the practice and results of applying the day-hospital system in an interventional radiology clinic. MATERIALS AND METHODS: From Oct. 2004 to Dec. 2005, the day-hospital system was applied to various interventional procedures with using a part of the recovery room of an angiography suite as a facility for hospital admission. The study included 91 cases in 73 patients. The source of the patient referral, the procedures, hospital courses and complications were analyzed and questionnaire surveys were conducted for the available 55 patients. RESULTS: Among the patients, 70% (n=64) were referred from other departments, 5% (n=5) from other hospitals, 5% (n=4) were new patients and 20% (n=18) were re-admissions. The procedures included gastrointestinal, biliary, urinary, hemodialysis related- and implantable port related interventions. 96% (n=87) of the patients were successfully discharged in a day and admission to the general ward was only 4% (n=4). Minor complications occurred after discharges in 3% (n=3). The questionnaire survey revealed that 96% (n=53) of the patients were satisfied with the service and they were not anxious after discharge. CONCLUSION: Most of common interventional procedures were safely done under the day-hospital system with the patients being highly satisfied. The day-hospital system can be a good tool for establishing admitting privileges for an interventional radiology clinic.
