A 25-year-old man presented with a mass on the right medial canthus after a successful dacryo cys torhinostomy performed 3 years ago. On examination, there was a firm, nondepressible mass inferior to the medial canthal ligament and a linear vertical scar on the lateral wall of the nose. Syringing through the right lower punctum indicated his lacrimal system was patent. Computed tomography and magnetic resonance imaging disclosed a large cystic lesion in the lacrimal sac fossa. No bone erosion was detected. The mass was approached through a tear trough incision and completely resected...

BACKGROUND: Spinal epidural abscess is a rare condition with high morbidity and mortality, for which a delay in diagnosis and treatment can lead to irreversible neurologic deficit or even death. Although patients with spinal epidural abscess have systemic predisposing immunocompromised conditions, spinal intervention, or trauma, this condition has been reported as a result of perforation or fistulization arising from inflammatory bowel disease. We describe herein a rare case of spinal epidural abscess as a complication of ileal pouch anal anastomosis...

INTRODUCTION: The Rubinstein-Taybi syndrome and pancreas divisum are uncommon diseases in children. The Rubinstein-Taybi syndrome diagnosis is only clinical, and mental retardation and dysmorphic features mainly characterize it. The PD relates to idiopathic pancreatitis in 7.5% of patients suffering from this disorder. It has not been found any cases reported where these diseases are associated and the management of patients with pancreatitis associated with PD is still a challenge. CLINICAL CASE: A patient diagnosed with Rubinstein-Taybi syndrome has recurrent abdominal pain of six months and elevated pancreatic enzymes, he underwent a magnetic resonance imaging where pancreas divisum is suspected...

The accessory middle cerebral artery (MCA) is a common variation of the MCA that arises from the anterior cerebral artery. We report a patient with anastomosis of the accessory MCA with the main MCA, an extremely rare variant that we diagnosed by magnetic resonance (MR) angiography. Both partial maximum-intensity-projection and partial volume-rendering MR angiographic images obtained at 3 T are useful to identify such rare vascular variation.

PURPOSE: Surgical procedures for high imperforate anus have ranged from the posterior sagittal anorectoplasty (PSARP) to laparoscopic-assisted anorectoplasty (LAARP). PSARP bisects the sphincter muscle complex, introducing muscle injury and scarring. LAARP uses a straight trocar to traverse an often non-linear sphincter muscle complex. MRI-assisted LAARP (MRI-LAARP) guides the neorectum precisely through the middle of the entire sphincter complex along its trajectory. We present our experience utilizing MRI intraoperatively during LAARP...

BACKGROUND & AIMS: Although non-surgical methods produce high clinical success rates in the treatment of benign biliary stricture (BBS), conventional methods are not always successful in cases of severe biliary stricture or complete obstruction. Therefore, the efficacy of magnetic compression anastomosis (MCA) for treatment of refractory BBS was evaluated in a single-center, nonrandomized study. METHODS: MCA was performed in patients with BBS that was not resolved by conventional endoscopic or percutaneous treatments...

Glomus tumors are rare benign hamartomas arising from the neuromyoarterial glomus body, a highly specialized arteriovenous anastomosis responsible for thermoregulation. Although classically associated with a subungual location, less common extradigital glomus tumors can present a diagnostic challenge because of their rarity and nonspecific presentation. This case report adds to the literature of proven extradigital glomus tumors with documented pathologic and magnetic resonance imaging characteristics and describes their place in the differential for soft tissue mass of the wrist...

BACKGROUND AND AIMS: Magnetic compression anastomosis is a rescue technique for recanalization of complete biliary strictures. Here, we present magnetic compression anastomosis with novel through-the-scope magnets in patients with complete duct-to-duct anastomosis obstruction after liver transplantation. METHODS: The magnets were 2 and 2.4 mm in diameter, with a hole at the center for inserting a guidewire. One of the magnets was advanced through the scope up to the distal site of the stricture by using a 7F pusher...

We present the case of an 18-year-old male patient that was referred to our gastrenterology department with history of intermittent painless hematochezia since childhood. During such instances, he was diagnosed with bowel intussusception, eosinophilic gastroenteritis and inflammatory bowel disease at 4, 6 and 8 years old, respectively. He underwent treatment with 5-aminosalicylic acid for two years, without improvement of symptoms. He was then lost to follow-up until our observation. His physical examination was unremarkable except for digital rectal examination which found a nodular compressible mass by the palpating finger...

INTRODUCTION AND HYPOTHESIS: Rectovaginal fistula (RVF) is an abnormal epithelium-lined connection between the rectum and vagina. The primary effective treatment is surgical repair, but recurrence remains a challenge. Magnetic compression anastomosis (MCA), an alternative to suturing, has been developed to generate an anastomosis between various hollow viscera. We hypothesized that the MCA approach could be used to treat RVF. METHOD: We designed a novel MCA device for RVF treatment and evaluated the magnetic compression procedure in a RVF pig model in comparison with the traditional suturing procedure...

BACKGROUND: Children with a compromised inferior vena cava (IVC) were previously considered unsuitable for kidney transplantation because of the technical difficulties and the increased risk of graft thrombosis secondary to inadequate renal venous outflow. METHODS: We conducted a retrospective study of 11 transplants in 9 patients with end-stage renal disease and thrombosed IVCs who received adult kidney allografts between 2000 and 2015. The mean age at transplantation was 7...

BACKGROUND: Tricuspid valve regurgitation in reported in >20% of heart recipients. It severity has not only clinical impact, but it is also associated with increased mortality. Risk factors for developing tricuspid valve dysfunction include allograft rejection, donor/recipient pericardial cavity mismatch, preoperative transpulmonary gradient and vascular resistance, biatrial anastomosis technique, and biopsy-induced injury. Tricuspid valve annulus distention is reported to causative factor for most common type of tricuspid valve dysfunction after heart transplantation...

REVIEW
Milljae Shin, Jae-Won Joh
Apart from noticeable improvements in surgical techniques and immunosuppressive agents, biliary complications remain the major causes of morbidity and mortality after living donor liver transplantation (LDLT). Bile leakage and stricture are the predominant complications. The reported incidence of biliary complications is 15%-40%, and these are known to occur more frequently in living donors than in deceased donors. Despite the absence of a confirmed therapeutic algorithm, many approaches have been used for treatment, including surgical, endoscopic, and percutaneous transhepatic techniques...

BACKGROUND: Because of the unique electromagnetic characteristics of the magnetoelastic microwire, the changes in the pressure of a fluid will provoke a variation of the mechanical pressure on the sensor, which will cause a variation of its magnetization that will be detectable wirelessly. Thus, a wireless system can be developed for following up vascular surgery procedures. METHODS AND RESULTS: The sensor consists of a magnetoelastic microwire ring, which was integrated into an in vitro model with pulsatile flow...
