Placement of multiple metal stents (MS) for the management of high-grade malignant hilar biliary obstruction (MHBO) is useful,1,2 and biliary radiofrequency ablation (RFA) has been suggested to improve stent patency.3,4 However, to our knowledge, there are no reports of RFA procedures performed using a single-balloon endoscope (SBE) in patients with surgically altered anatomy. Here, we report a successful case of RFA combined with multiple MS placement using SBE in Roux-en-Y gastrectomy. This article is protected by copyright...

Accurate force simulation is essential to haptic simulators for surgical training. Factors such as tissue inhomogeneity pose unique challenges for simulating needle forces. To aid in the development of haptic needle insertion simulators, a handheld force sensing syringe was created to measure the motion and forces of needle insertions. Five needle insertions were performed into the neck of a cadaver using the force sensing syringe. Based on these measurements a piecewise exponential needle force characterization, was implemented into a haptic central venous catheterization (CVC) simulator...

INTRODUCTION: True left-sided gallbladder (LSG) is a rare finding that may present with symptoms similar to those of a normally positioned gallbladder. Moreover, it may be missed by preoperative imaging studies such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), or endoscopic ultrasound. True left-sided gallbladder is a surgical challenge and surgical technique may need to be modified for the completion of laparoscopic cholecystectomy. PRESENTATION OF CASE: In this case report, we present a case of true left-sided gallbladder that produced right-sided abdominal symptoms...

Primary liver cancer-including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC)-incidence is increasing and is an important source of cancer-related mortality worldwide. Management of these cancers, even when localized, is challenging due to the association with underlying liver disease and the complex anatomy of the liver. Although for ICC, surgical resection provides the only potential cure, for HCC, the risks and benefits of the multiple curative intent options must be considered to individualize treatment based upon tumor factors, baseline liver function, and the functional status of the patient...

We herein reported a rare case of an occult fallopian tube carcinoma first detected from the diaphragm metastasis. An 83-year-old woman who had a 30-mm tumor on the right diaphragm underwent radical resection. Pathologically, the tumor was diagnosed as a high-grade serous adenocarcinoma, suggesting metastasis from the pelvic visceral carcinoma. Although the primary site could not be detected by imaging examinations, laparoscopy revealed multiple peritoneal disseminations; therefore, total hysterectomy was performed...

With improved surgical techniques and medical management for patients with congenital heart diseases, more patients are living longer and well into adulthood. This improved survival comes with a price of increased morbidity, mainly secondary to increased risk of tachyarrhythmias. One of the major arrhythmias commonly encountered in this subset of cardiac patients is AF. Similar to the general population, the risk of AF increases with advancing age, and is mainly secondary to the abnormal anatomy, abnormal pressure and volume parameters in the hearts of these patients and to the increased scarring and inflammation seen in the left atrium following multiple surgical procedures...

OBJECTIVE: The endoscopic endonasal approach to the anatomically complex lateral skull base presents technical challenges. The use of the Eustachian tube as a landmark to identify the petrous internal carotid artery has recently been reported, and this study aims to define the anatomical relationship between the Eustachian tube and its surrounding structures using cadaveric dissection and radiologic analysis. METHODS: To clarify the relationship of the Eustachian tube with its surrounding structures, we performed endoscopic and microscopic dissection of four adult cadaveric heads, and analyzed computed topography scans from 20 patients...

BACKGROUND: Reshaping the nose can be achieved following 3 main concepts: preservation and reshaping of normal anatomy, resection of nasal deformities, reconstruction of nasal framework. Time, experience and nasal anatomic knowledge are keys to understand nasal biomechanics. OBJECTIVES: To describe how experience and morphodynamic anatomy lead to a new concept of sequential primary rhinoplasty, resulting in reducing revision rhinoplasties. METHODS: Through 36 years' experience in different rhinoplasty procedures, 25 years in personal anatomic studies of the nose and reviewing the last 15 years including 600 patients who underwent new concepts in primary rhinoplasty out of 1200 patients operated during this period, the author analyzes how nasal anatomic layers, surgical approaches, and morphological effect of the time interact to modify the aesthetic results according to current rhinoplasty concepts...

Identification of the parathyroid glands (PGs) during thyroid surgery may prevent their inadvertent surgical removal and prevent postoperative hypoparathyroidism. However, identification of the PGs does not guarantee their function, and their vascular supply needs to be preserved as well. The recent introduction of intraoperative indocyanine green (ICG) fluorescent angiography of the PGs during thyroid surgery allows for the appraisal of the vascular anatomy and evaluation of PG function. The use of this tool could lead to a significant reduction in the rate of postoperative hypoparathyroidism, as it allows surgeons to adapt their surgical technique for the preservation of the PGs...

Pelvic floor dysfunction (PFD) is a common condition that typically affects women older than 50 years and decreases the quality of life. Weakening of support structures can involve all three pelvic compartments and cause a combination of symptoms, including constipation, urinary and fecal incontinence, obstructed defecation, pelvic pain, perineal bulging, and sexual dysfunction. The causes of PFD are complex and multifactorial; however, vaginal delivery is considered a major predisposing factor. Physical examination alone is limited in the evaluation of PFD; it frequently leads to an underestimation of the involved compartments...

Lateral bony decompression may offer several biomechanical advantages and has become a commonly used surgical approach. Preoperative imaging plays a key role in surgical planning by providing information about the locoregional anatomy. The marrow space of the greater wing of the sphenoid is a focal point of the decompression surgery based on the volume that it occupies. Several vessels pass through the sphenoid bone, but most are small caliber vessels. The authors describe a case of an uncommon anatomical variant of the cranial diploic venous system in which the anterior transverse diploic vessel traverses the marrow space of the sphenoid...

BACKGROUND: Perforator flaps have unique advantages that may overcome the shortcomings of conventional approaches to myelomeningocele reconstruction. However, identifying and dissecting tiny perforators in neonates is arduous. We have overcome these obstacles with a freestyle flap approach that uses duplex ultrasonography to locate perforator vessels, allowing for limited superficial dissection. This report describes the duplex ultrasonography-assisted freestyle pedicled perforator flap technique for closure of myelomeningocele defects, with long-term clinical outcomes...

BACKGROUND: Deep enteroscopy-assisted ERCP (DEA-ERCP) in post-bariatric Roux-en-Y (RY) anatomy is challenging. Laparoscopy-assisted ERCP (LA-ERCP) or EUS-directed transgastric ERCP (EDGE) are technically easier and faster, but are more invasive and morbid procedures. Therefore, we have used DEA-ERCP as our first-line approach, reserving EDGE and LA-ERCP for cases in which adjunctive techniques that cannot be performed through an enteroscope are required (eg, EUS-FNA, SO manometry), or DEA-ERCP failures...

Molecular breast imaging (MBI), also called breast-specific gamma imaging (BSGI), has been an integral component of our breast imaging practice for over a decade. Unlike mammography and ultrasound that are based on anatomy, MBI is a physiologic approach to breast cancer detection. MBI detects additional foci of occult breast cancer in 9.0% of women with newly diagnosed breast cancer, has a high sensitivity for detecting high-risk lesions, and detects 98% of invasive breast cancer and 91.0% of ductal carcinoma in situ...

INTRODUCTION: Severely impacted teeth with atypical root anatomy do not respond well to orthodontic traction after surgical exposure. Consequently, they are often removed, but replacing them with dental prostheses can prove difficult in patients who are still growing. Thus, autotransplantation seems to be the only way to preserve a natural tooth and the alveolar bone. MATERIALS AND METHODS: An upper central incisor impacted in the region of the nasal cavities with an open apex was diagnosed in an 8...

The rendezvous approach is a salvage technique after failure of endoscopic retrograde cholangiography (ERC). In certain circumstances, percutaneous-endoscopic rendezvous (PE-RV) is preferred, and endoscopic ultrasound-guided rendezvous (EUS-RV) is difficult to perform. We aimed to evaluate PE-RV outcomes, describe the PE-RV techniques, and identify potential indications for PE-RV over EUS-RV.Retrospective analysis was conducted of a prospectively designed ERC database between January 2005 and December 2016 at a tertiary referral center including cases where PE-RV was used as a salvage procedure after ERC failure...
