Endoscopic surgery of the rhinobasis with a computer-assisted localizer

1996

The endoscope is useful for the diagnosis and surgical therapy of diseases of the nose, the paranasal sinuses and its neighboring regions, and allows for microinvasive, functional approaches. The reduced invasiveness of therapeutic procedures is sometimes accompanied by insufficient clearness of the surgical field, however. This significant problem is solved by the computer-assisted-surgery (CAS) system, an intraoperative localizer. It allows continuous orientation based on three-dimensional reconstructed preoperative CT scans with superimposed positioning of the endoscope. We have now adapted CAS for endoscopic sinus surgery, which meant that a variety of visualization methods were tested.…

High-Definition Imaging in Spinal Neuroendoscopy

2010

BACKGROUND Spinal endoscopy is still under controversial discussion. An often acclaimed critic is the poor endoscopic image quality in comparison with the microscope. Since high-definition digital cameras have recently been introduced into spinal neuroendoscopy, the aim of the current study is to examine whether superior image quality has a relevant impact on intraoperativen orientation. MATERIAL AND METHODS A lumbar endoscopic discectomy was recorded simultaneously in High-Definition resolution (HD) and Standard-Definition resolution (SD). 10 experienced spinal surgeons were asked to identify predefined as well as not predefined anatomic structures in HD and SD resolution. Additionally, th…

German Survey on EUS-Guided Diagnosis and Management of Gastrointestinal Stromal Tumors (GISTs) - Evidence or "Gut-Feeling"?

2015

To examine practice patterns of endosonographers in diagnosing and managing gastrointestinal stromal tumors (GISTs) in Germany.A modified published survey (Ha et al., Gastrointest Endosc 2009) was sent to endosonographic ultrasound (EUS) customers in Germany. The survey was also publicized on the homepage of an EUS interest group. To avoid duplicate opinions, participants were asked to return one survey per institution.142 centers of roughly 850 German EUS centers responded. 25 % were from University hospitals and 74 % from community hospitals. 61 % performed 2 EUS scans for suspected subepithelial lesions/week. Although 97 % of respondents believed that tissue acquisition with CD117 immuno…

Biliopancreatic Endoscopy in Altered Anatomy

2021

Background and Objectives: Anatomical post-surgical alterations of the upper gastrointestinal (GI) tract have always been challenging for performing diagnostic and therapeutic endoscopy, especially when biliopancreatic diseases are involved. Esophagectomy, gastrectomy with various reconstructions and pancreaticoduodenectomy are among the most common surgeries causing upper GI tract alterations. Technological improvements and new methods have increased the endoscopic success rate in these patients, and the literature has been rapidly increasing over the past few years. The aim of this systematic review is to identify evidence on the available biliopancreatic endoscopic techniques performed i…

Endoscopic ultrasound and early diagnosis of pancreatic cancer

2007

Incidence of pancreatic cancer has increased, but prognosis remains poor. Curative treatment is dependent on early diagnosis. Endoscopic ultrasound (EUS) has been described as highly sensitive and accurate in staging, superior to other imaging modalities in early publications. With rapid advances in technology, other imaging techniques have reached better results. EUS still has the highest accuracy in assessing tumor size and lymph node involvement. For assessment of tumor respectability, a combination of a computed tomography (CT) scan and EUS seems to be the procedure with the highest accuracy. Promising new techniques might improve the diagnostic yield of EUS. But there are several reaso…

Advances in endoscopic imaging of colorectal neoplasia.

2010

Colon cancer screening is arguably the most important activity performed by gastroenterologists. Recent decreases in rates of death from colorectal cancer indicate that screening methods such as colonoscopy have a positive impact. There is still room for improvement, however, particularly in prevention of right-sided colon cancer. Practice issues, such as making colonoscopy more comfortable, safer, and less costly, are keys to continued success in cancer prevention. Colonoscopy techniques, technologies, and quality control measures have advanced to improve detection, classification, and removal of early neoplasias. In particular, slow, careful inspection of the colon by gastroenterologists …

Ileo-ileal invagination--a cause of recurrent mid-gastrointestinal bleeding: diagnostic and endoscopic therapy by means of push-and-pull enteroscopy.

2008

The types of lesions that cause bleeding in the small bowel are similar to those found in other areas in the gastrointestinal tract, such as vascular malformations, ulcers and inflammatory lesions, neoplasms and other less common lesions like Meckel's diverticulum. This report describes three patients with suspected mid-gastrointestinal bleeding with no significant past medical history. Before presenting to our unit the diagnostic work-up such as oesophagogastroduodenoscopy, colonoscopy and radiological small bowel imaging such as conventional enteroclysis or magnet resonance imaging enteroclysis had been performed without detecting any bleeding source. Capsule endoscopy suspected an angiod…

Endoscopic interventions in the small bowel using double balloon enteroscopy: feasibility and limitations.

2007

Double-balloon enteroscopy (DBE) is a new endoscopic tool that not only allows diagnostic workup of small bowel diseases, but also makes it possible to carry out therapeutic interventions. However, for a variety of reasons, endoscopic therapy appears to be more difficult to carry out deep in the small bowel than in the upper or lower gastrointestinal tract.The purpose of this study was to evaluate the acute technical success and acute complication rate of DBE.Between June 2003 and July 2006, 353 patients (152 women, 201 men; mean age 60.3 +/- 17.1 yr) with suspected or known small bowel disease underwent 635 consecutive DBE procedures. The majority of the patients were suffering from midgas…
