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.…

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…

Prospective comparison of push enteroscopy and push-and-pull enteroscopy in patients with suspected small-bowel bleeding.

2006

BACKGROUND The management of patients with suspected mid-gastrointestinal bleeding has in the past been AND AIMS: difficult, as push enteroscopy (PE) only allows limited endoscopic access for diagnosis and treatment. Recently published uncontrolled data on push-and-pull enteroscopy (PPE) using the double-balloon technique suggest that this new method has a high diagnostic yield and therapeutic efficacy. A prospective controlled study was therefore carried out to compare PPE with PE as the common nonsurgical gold standard method. METHODS: The diagnostic yield, complications, and various examination parameters were compared in 52 consecutive patients with suspected mid-gastrointestinal bleedi…

Transvalvular enteroscopy using a mother-baby endoscope system: a new approach to the distal ileum.

1997

In the past decade various endoscopes have been developed to examine the small bowel, with two principal procedures established: sonde-type enteroscopy and push-type enteroscopy. The main indication is gastrointestinal bleeding of obscure origin. Push-type enteroscopy has proved itselfto be useful for the investigation ofdiseases of the small intestine. 1 The mean instrumental insertion length published by different working groups varied between 50 and 90 cm past the ligament of Trei tzfl 2 The small bowel examination area is limited to the jejunum. The alternative method is sonde-type enteroscopy that allows an insertion length of 140 (30 to 200) cm. 3, 4 Disadvantages of this type of ente…

Frame-based and frameless endoscopic procedures in the third ventricle.

1997

Stereotactic guidance is useful for planning an accurate trajectory to the third ventricle. A guiding block with a ball joint was developed for frame-based endoscopy and adaptors for arm-based and armless navigation systems. Between 1992 and 1996, 52 patients were operated on endoscopically in the third ventricle under stereotactic guidance. Thirty-eight ventriculostomies, 13 biopsies and 10 cystic lesions were performed. The coordinates of two points were calculated; one in the foramen of Monro and the second in the third ventricle. The ventriculostomy was performed under endoscopic control bluntly with a Fogarty catheter in front of the basilar artery. Twenty-seven (71%) of the patients h…

The Role of Endoscopy in the Treatment of Acute Traumatic Anterior Epidural Hematoma of the Cervical Spine: Case Report

1997

OBJECTIVE AND IMPORTANCE: Epidural hematoma (EDH) of the spine represents an uncommon neurosurgical disorder that sometimes requ;res emergent surgical decompressive therapy. Traumatic EDH of the cervical spine is exceedingly rare. The hematoma is usually located dorsally in the epidural space. We present one case of acute EDH located ventrally in the cervical spine. Special emphasis is placed on the role of spinal endoscopy in surgical treatment. CLINICAL PRESENTATION: After a fall from a tree, a 69-year-old man with rapidly increasing tetraparesis was referred to our institution. Plain films of the cervical spine revealed nothing abnormal. The results of computed tomography were highly sus…

Collagenous colitis: new diagnostic possibilities with endomicroscopy

2006

Collagenous colitis is a kind of microscopic colitis. It is characterized by chronic watery diarrhea and abdominal pain. The etiology is still unknown. So far, for the diagnose a histological evaluation was necessary with the presence of thickened subepithelial collagneous bands in the lamina propria. A new developed endoscope with a confocal laser allows analysing cellular and subcellular details of the mucosal layer at high resolution in vivo. In this case report we describe for the first time to diagnose collagenous colitis during ongoing colonoscopy by using this confocal endomicroscopy. In a 67 year old female patient with typical symptoms the characteristic histological changes could …

Extraction of Entrapped Capsules from the Small Bowel by Means of Push-and-Pull Enteroscopy with the Double-Balloon Technique

2005

The new technique of push-and-pull enteroscopy using the double-balloon technique (double-balloon enteroscopy) makes it possible to remove swallowed foreign bodies causing intestinal obstruction deep in the small bowel without the need for surgical laparotomy. This report describes two cases of enteroscopic removal of entrapped capsules. In one patient with acute recurrent intestinal bleeding and recurrent abdominal pain, Crohn's disease had been suspected on capsule endoscopy. The second patient, with known Crohn's disease, was suffering from abdominal pain and underwent capsule endoscopy for investigation of the small bowel. Prior enteroclysis had not revealed stenoses in either patient. …
