Gastric banding is a popular method for the treatment of morbid obesity. Amongst complications, gastric erosion remains uncommon but could prove fatal. Multiple techniques, from open surgery to endoscopic and standard laparoscopic technique for their removal, have been previously detailed in the literature. However, only a few reports have mentioned their total laparoscopic transgastric removal in the literature. Herein, we report a successful removal of an eroding gastric band with its technical suggestion in a 43-year-old female patient 22 months following its application...

BACKGROUND: Presurgical planning allows anticipating intraoperative difficulties, increasing efficiency, and reducing risks. Neuroendoscopy is a minimally invasive technique whose related complications have been focused on cortical function and surface vessels injury. However, white matter disruption has been insufficiently acknowledged. OBJECTIVE: To present a new surgical planning method based on diffusion tensor image that allows quantifying subcortical transgression and optimizing neuroendoscopic trajectories...

INTRODUCTION: Esophageal replacement is a surgical alternative once native esophagus can't be preserved. Different organs and routes for the replacement have been described, being the retroesternal route the least used. The aim is to present our results using gastric tube esophagoplasty with a retroesternal approach. PATIENTS AND METHODS: We performed a retrospective and descriptive study of 11 patients operated from 2000 to 2015. Median age at surgery was 2.2 years (5 months-9 years) and median weight was 11...

Radiology examinations play a major role in the diagnosis, management, and surveillance of small bowel diseases and are complementary to endoscopic techniques. Computed tomography enterography and magnetic resonance enterography are the cross-sectional imaging studies of choice for many small bowel diseases. Angiography still plays an important role for catheter-directed therapies. With the emergence of hybrid imaging techniques, radionuclide imaging has shown promise for the evaluation of small bowel bleeding and Crohn disease and may play a larger role in the future...

Esophageal cancer (EC) is the fourth leading cause of cancer death in China. Despite a lot of advances in diagnosis and therapy, the survival rate of patients with EC is low. There is urgent need for a variety of methods and techniques to improve the survival time and alleviate the lesions of EC. Nowadays, alternative and less invasive approaches to the treatment of ECs are being identified. Here, we review several main interventional methods at different stages of EC, including endoscopic resection, stent placement, arterial infusion, photodynamic therapy, and radiofrequency ablation...

Therapeutic access to the biliary system is generally limited to endoscopic or percutaneous approaches. A variety of percutaneous transhepatic biliary interventions are applicable for the diagnosis and treatment of biliary system pathologies, the majority of which may be performed in conjunction with one another. The backbone of nearly all of these interventions is percutaneous transhepatic cholangiography for opacification of the biliary tree, after which any number of therapeutic or diagnostic modalities may be pursued...

Choledocholithiasis occurs in up to approximately 20% of patients with cholelithiasis. A majority of stones form in the gallbladder and then pass into the common bile duct, where they generate symptoms, due to biliary obstruction. Confirmatory diagnosis of choledocholithiasis is made with advanced imaging, including magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP). Treatment varies locally; however, ERCP with sphincterotomy is most commonly employed with a high degree of success...

Resection remains the mainstay of treatment for craniopharyngiomas with the goal of radical resection, if safely possible, to minimize the rate of recurrence. Endoscopic endonasal and microscopic transcranial surgical approaches have both become standard methods for the treatment for craniopharyngiomas. However, the approach selection paradigm for craniopharyngiomas is still a point of discussion. Choosing the optimal surgical approach can play a significant role in maximizing the extent of resection and surgical outcome while minimizing the risks of potential complications...

Obesity is one of the most important public health conditions worldwide. Bariatric surgery for severe obesity is an effective treatment that results in the improvement and remission of many obesity-related comorbidities, as well as providing sustained weight loss and improvement in quality of life. Contemporary bariatric operations include Roux-en-Y gastric bypass, sleeve gastrectomy, adjustable gastric band and the duodenal switch. The vast majority of these procedures are now performed using laparoscopic technique, the main advantages of which include rapid recovery, the reduction of postoperative pain and the reduction of wound-related complications, compared with open surgery...

Laparoscopic cholecystectomy is the standard of care for cholelithiasis as well as cholecystitis. However, in the setting of Mirizzi syndrome or gangrenous cholecystitis where the critical view cannot be ascertained, subtotal cholecystectomy may be necessary. Using the robot-assisted approach, difficult cholecystectomies can be performed upfront without need for partial cholecystectomy. Even in the setting of Mirizzi syndrome where severe scarring and fibrosis are evident, definitive cholecystectomy and takedown of the cholechystocholedochal fistula can be performed in a safe and feasible fashion following successful endoscopic common bile duct stent placement...

Fourier ptychography (FP) is a recently proposed computational imaging technique for high space-bandwidth product imaging. In real setups such as endoscope and transmission electron microscope, the common sample motion largely degrades the FP reconstruction and limits its practicability. In this paper, we propose a novel FP reconstruction method to efficiently correct for unknown sample motion. Specifically, we adaptively update the sample's Fourier spectrum from low spatial-frequency regions towards high spatial-frequency ones, with an additional motion recovery and phase-offset compensation procedure for each sub-spectrum...
