OBJECTIVE: Colorectal cancer is the fourth most common cancer worldwide, with a lifetime risk of around 20%. Current solutions do not allow clinicians to objectively assess tissue abnormality during endoscopy and perioperatively. A solution capable of objectively assessing samples in real time could greatly improve the treatment process. A solution that can be integrated in minimally invasive diagnostics and management strategies to provide real-time point-of-care information would be greatly transformative...

Pseudopolyps are a well described entity in the literature and even though the exact pathogenesis of their formation is not completely understood, they are considered non-neoplastic lesions originating from the mucosa after repeated periods of inflammation and ulceration associated with excessive healing processes. Their occurrence is less common in Crohn's disease than in ulcerative colitis, and their overall prevalence ranges from 4% to 74%; moreover, they are found more often in colon but have been detected in other parts of the gastrointestinal tract as well...

Gastroesophageal reflux disease (GERD) has a large economic burden with important complications that include esophagitis, Barrett's esophagus, and adenocarcinoma. Despite endoscopy, validated patient questionnaires, and traditional ambulatory pH monitoring, the diagnosis of GERD continues to be challenging. Areas covered: This review will explore the difficulties in diagnosing GERD with a focus on new developments, ranging from basic fundamental changes (histology and immunohistochemistry) to direct patient care (narrow-band imaging, impedance, and response to anti-reflux surgery)...

BACKGROUND: Intraoperative microscopic fluorescence angiography using indocyanine green (ICG) provides visual information on real-time blood flow. However, this method cannot be applied for lesions that are not visible under microscopic imaging because excitation light does not reach the targeted vascular structures. Endoscope-integrated ICG video-angiography has recently been advocated to compensate for this limitation. This is the first reported case of a spinal arteriovenous malformation in which endoscope-integrated ICG video-angiography was successfully used...

BACKGROUND: Gastroesophageal reflux disease (GERD) is common in patients with obesity. Diagnosing GERD is important as bariatric operations have different influence on GERD. We assessed reflux symptoms and objective findings prior to surgery. METHODS: Work-up included esophageal symptoms quantification by VAS-scores, esophagogastroduodenoscopy (EGD) and 24-h impedance-pH (imp-pH) monitoring off PPI therapy. Imp-pH was classified as abnormal if either %time pH<4 was abnormal, total number of reflux episodes was elevated or symptom index (SI) was positive...

Endoscopic or minimally invasive surgery popular as keyhole surgery is a medical procedure in which endoscope (a camera) is used, and it has gained broad acceptance with popularity in several surgical specialties and has heightened the standard of care. Oral and maxillofacial surgery is a modern discipline in the field of dentistry in which endoscopy has developed as well as widely used in surgeries and is rapidly gaining importance. The use of different visual as well as standard instruments such as laparoscopic and endoscopic instruments, and high-powered magnification devices, has allowed physicians to decrease the morbidity of many surgical procedures by eliminating the need for a large surgical incision...

We report two cases of melanomas in patients who developed intestinal metastasis despite other metastatic sites responding to nivolumab and despite the patients having favorable findings such as vitiligo and normal lactate dehydrogenase. The first case is an 85-year-old man who had been administrated nivolumab for lung/cutaneous metastases. After 22 courses of nivolumab therapy, fever and anorexia had appeared and his bodyweight had decreased. An intussusception on the ileocecal valve was revealed by computed tomography, and emergency surgery revealed metastatic lesions on the colon...

In 1993, a surgical protocol for dynamic upper airway reconstruction in patients with obstructive sleep apnea (OSA) was published, and it became commonly known as the Stanford phase 1 and 2 sleep surgery protocol. It served as a platform on which research and clinical studies have continued to perfect the surgical care of patients with OSA. However, relapse is inevitable in a chronic condition such as OSA, and a subset of previously cured surgical patients return with complaints of excessive daytime sleepiness...

INTRODUCTION: Despite greater than 60,000 nonfatal firearm injuries per year in the United States, retained shrapnel is a relatively rare cause of systemic lead toxicity with less than 100 cases reported in the medical literature since 1867. While intra-articular retained shrapnel as a cause of lead toxicity is well-described, extra-articular fragments are less well known to cause symptomatic disease. CASE REPORT: A 31-year-old man initially presented with abdominal pain, constipation, jaundice, and elevated liver transaminases approximately 3 weeks after suffering a left lower extremity injury during athletic activity...

Narrow-band imaging (NBI) is an optical technique enhancing mucosal vasculature. The aim of this study is to assess the effectiveness of rigid NBI endoscopy in the early detection of second primaries or local recurrences after treatment for oral (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC), its advantage over standard white-light (WL) endoscopy, and the influence of previous radiotherapy, the learning curve, and lesion site. Between January 2013 and June 2015, 195 patients treated for OSCC or OPSCC with surgery alone (group A) or radiotherapy with or without surgery and/or chemotherapy (group B) underwent additional follow-up assessments using NBI...

OBJECTIVE: The objective of the study was to evaluate the safety and effectiveness of three-dimensional (3D) endoscopy for thyroidectomy and compare it to two-dimensional (2D) endoscopy. The major limitations of conventional endoscopy include its lack of depth perception and tactile feedback. The 3D endoscopy technique, which involves 3D imaging, is widely used. However, few reports have described the use of 3D endoscopic systems in thyroid surgery. METHOD: In this single-institutional study, 103 consecutive patients who underwent endoscopic thyroidectomy between July 2013 and April 2014 were enrolled...
