There has been significant evolution over time from external headlight sinus surgery to endoscopic sinus surgery(ESS). ESS was pioneered by Messenklinger, who discovered that the sinuses had a predetermined mucociliary clearance pattern towards the natural ostium irrespective of additional openings into the sinuses. This philosophy of opening the natural ostium of the diseased sinus was then po...

We thank Drs. Mandal and Goel for their interest in our work, but we disagree with their interpretation of the literature compared with our findings. While Waldert and associates did indeed find a correlation between a longer delay to nephroureterectomy (NUx) and more advanced stage, they did not report metastasis-free survival. Moreover, they found no difference in cancer-specific survival. Th...

BACKGROUND/AIMS Hemobilia is a rare cause of upper gastrointestinal bleeding. Endoscopic retrograde cholangiopancreaticography (ERCP) is considered to be an excellent diagnostic and treatment modality. Thirty-seven cases of hemobilia with different underlying pathologies were analyzed to illustrate clinical features and to evaluate the role of endoscopic management. METHODS A total of 37 pati...

This special September issue of Clinical Endoscopy will discuss various aspects of diagnostic and therapeutic advancement of gastrointestinal (GI) endoscopy, explaining what is new in digestive endoscopy and why international network should be organized. We proposed an integrated model of international conference based on the putative occurrence of Digestive Endoscopy Networks. In International...

Pancreatic cancer is the fourth leading cause of cancer-related death in the United States and one of the leading causes of cancer mortality in the United States. Due to its aggressive behavior and lack of effective therapies, palliation plays a critical role in the management of the disease. Most patients with pancreatic cancer suffer from severe pain, which adversely predicts prognosis and si...

Urothelial carcinoma of the upper urinary tract represents only 5% of all urothelial cancers. The 5-year cancer-specific survival in the United States is roughly 75% with grade and stage being the most powerful predictors of survival. Nephroureterectomy with excision of the ipsilateral ureteral orifice and bladder cuff en bloc remains the gold standard treatment of the upper urinary tract uroth...

In patients with inoperable hilar cholangiocarcinoma (HCCA), palliative endoscopic or percutaneous drainage provides benefits in terms of symptomatic improvement and quality of life. Endoscopic biliary stent placement is considered the gold standard, with metal stents preferred over plastic stents in patients with more than three months of life expectancy. However, the endoscopic management of ...

Epistaxis is defined as bleeding from the nose. It is one of the most common rhinological emergencies, making the management of posterior epistaxis a challenging problem for ENT surgeons. Conventional management options in form of chemical cauterisation, anterior nasal packing and posterior nasal packing, are not so much effective and satisfactory. Objective: The objective of this study was to ...

Management of hydrocephalus is the most beneficial indication for endoscopy. To cure hydrocephalus and thereby render an individual shunt independent is a great achievement. The standard and the most commonly performed endoscopic procedure is endoscopic third ventriculostomy. However, the field of neuroendoscopy is prepared to extend itself beyond just the ventriculostomy procedure. The neuroen...
