Endoscopic retrograde cholangiopancreatography (ERCP) has become the mainstay of therapy for pancreatobiliary diseases. While ERCP is safe and highly effective in the general population, the procedure remains challenging or impossible in patients with surgically altered anatomy (SAA). Endoscopic ultrasound (EUS) allows transmural access to the bile or pancreatic duct (PD) prior to ductal draina...

BACKGROUND Although percutaneous endoscopic gastrostomy may be complicated by iatrogenic bowel injury, most clinicians consider a small pneumoperitoneum on radiographs obtained after the procedure a benign finding of little clinical consequence. The possibility of a relationship between findings of early pneumoperitoneum after percutaneous endoscopic gastrostomy and subsequent iatrogenic bowel ...

BACKGROUND The effectiveness of transoral microsurgery for early-stage glottic cancer relies on the possibility to obtain adequate exposure of the lesion. The purpose of this study was to design a new surgical technique allowing efficient endoscopic removal of these tumors in patients with unsatisfactory transoral exposure. METHODS A minimal invasive access to the glottis, made through the th...

INTRODUCTION Laparoscopic-assisted colonic resection has been well described for multiple surgical indications and typically requires an abdominal incision for specimen removal that is associated with most of the postoperative pain. We report the total laparoscopic modified Duhamel operation for megacolon in combination with transanal endoscopic microsurgery for transanal specimen retrieval and...

Background and Aim: Several surgical techniques have been so far used for treating Cerebrospinal Fluid (CSF) leakage (rhinorrhea) such as using abdominal fat or fascia lata, but these methods have complications such as the presence of several surgeons in variable fields in the operating room or cosmetic complications for donors such as the surgical scar. This study aimed to investigate using bu...

BACKGROUND Post-operative cerebrospinal fluid (CSF) leaks are a common complication of endoscopic pituitary surgery and account for a significant proportion of hospital costs associated with this procedure. Tisseel® is a tissue glue commonly used as an adjunct in dural repair but is not optimal for this purpose. DuraSeal® has several properties advantageous for dural repair but is not widely ac...

OBJECTIVE Aneurysms of the vertebral artery are rare, comprising less than 5% of all aneurysms. They can present with subarachnoid hemorrhage, medullary compression, and cranial neuropathies. In consideration of their surrounding regional anatomy, they present a formidable surgical challenge to the neurosurgeon using traditional techniques. Recent advances in endoscopic transnasal surgery have ...

BACKGROUND Dacrocystorhinostomy (DCR) is an operation used to treat nasolacrimal duct obstruction. Essentially there are two approaches: external and endoscopic. Several modalities are used in endoscopic DCR; all aiming to improve success rate, reduce complications, and shorten operative time. Both kerrison punch and drill are widely used in endoscopic DCR with non-conclusive knowledge about di...

AIM The aim of this study was to analyze clinical findings and treatment outcomes of patients with endoscopic retrograde cholangiopancreatography complications. BACKGROUND Endoscopic retrograde cholangiopancreatography has become a very common procedure for the evaluation and treatment of biliary and pancreatic diseases. PATIENTS AND METHODS A retrospective review of 2447 endoscopic retrogr...

To review recent advances in endoscopic techniques for treating intraventricular lesions via transcortical passage. Articles in PubMed published since 2000 were searched using the keywords 'endoscopy,' 'endoscopic,' and 'neuroendoscopic.' Of these articles, those describing intraventricular lesions were reviewed. Suprasellar arachnoid cysts (SACs) can be treated with ventriculo-cystostomy (VC) ...
