Frameless Neuronavigation Applied to Endoscopic Neurosurgery
2000
Objective: We retrospectively analyzed the indications, surgical techniques, and applicability of frameless neuronavigation to endoscopic procedures in a heterogeneous group of 15 patients. Material and Methods: In 8 patients indications for surgery were cystic lesions, in 3 patients intraventricular tumors, and in 4 patients occlusive hydrocephalus. The mean age was 39 years (range 9 - 76 years). The follow-up period ranged from 5 - 24 months (mean 10 months). Frameless neuronavigation was accomplished with the “operating arm system” in 10 cases and with the “optical tracking system” in 5 cases (RADIONICS, Burlington, USA). Results: In all 15 cases, neuronavigation sufficiently provided an…
Endoscopic Treatment of Arachnoid Cysts
2010
Background Surgical treatment of arachnoid cysts remains under debate. Although many authors favor endoscopic techniques, others attribute a higher recurrence rate to the endoscope. Objective The authors report their experience with endoscopic procedures for arachnoid cyst. Methods All pure endoscopic procedures for arachnoid cysts performed by the authors were analyzed. Particular reference was given to surgical complications and patient outcome in relation to cyst location and endoscopic technique. Results Sixty-six endoscopic procedures were performed in 61 patients (mean age, 28 years; range, 23 days to 74 years; 35 males, 26 females). The main presenting symptoms were cephalgia (61%), …
Small-Bowel Diagnosis in Patients with Familial Adenomatous Polyposis: Comparison of Push Enteroscopy, Capsule Endoscopy, Ileoscopy, and Enteroclysis
2009
BACKGROUND: Conventional upper endoscopy (EGD), EGD with side-view endoscope and ileoscopy are established procedures for endoscopic evaluation of patients with familial adenomatous polyposis (FAP). However, we still have little data on the frequency and relevance of adenomas in those parts of the small bowel which are not accessible to EGD and ileoscopy. Adenomas distal to the duodenum are found more often in FAP patients with known duodenal adenomas. The question is, whether these patients can benefit from additional endoscopic and/or radiographic examinations. METHODS: Between July 2001 and August 2006 we performed comparative small bowel studies with push enteroscopy (PE), capsule endos…
Subfascial Endoscopic Perforator Surgery With Tumescent Local Anesthesia
2002
background. Subfascial endoscopic perforator surgery (SEPS) has become an established procedure. objective. To evaluate SEPS with tumescent local anesthesia (TLA) using an single-port device originally designed for that purpose. methods. Patients selected for SEPS received subcutaneous infiltration of TLA into the medial aspect of the calf 20 minutes before surgery. Bipolar coagulation and dissection were used to treat incompetent perforators. results. Fifty-one patients with 67 legs of CEAP stages C3–C6 underwent SEPS with TLA. In 40 patients or 53 legs (79.1%) TLA alone allowed successful completion of the SEPS procedure. Five patients with 7 legs (10.4%) required additional intravenous a…
Endoscopic and endoscope-assisted neurosurgical treatment of suprasellar arachnoidal cysts (Mickey Mouse cysts).
2005
Suprasellar arachnoid cysts represent less than 10% of all intracranial arachnoid cysts. Some of them may be quiescent throughout life, some may become symptomatic as they become enlarged and some disappear spontaneously. In this study we discuss the surgical strategies for endoscopic and endoscope-assisted treatment of suprasellar (Mickey Mouse) cysts and analyze the clinical results and experience collected over some years in our department upon doing these operations routinely. Between December 1996 and December 2003, 13 patients (7 female and 6 male patients), mean age 29 years, underwent endoscopic or endoscope-assisted procedures for suprasellar cysts at our department. The indication…
Wireless Capsule Endoscopy in a Patient with Obscure Occult Bleeding
2002
A case of obscure/occult bleeding in a 39-year old man with a 7-year history of chronic fatigue and iron-deficiency anemia is presented here. Esophagogastroduodenoscopy, push enteroscopy, ileocolonoscopies, and a magnetic resonance imaging small-bowel follow-through did not reveal any abnormalities. Multiple inflammatory lesions with fibrin-covered ulcers and petechial bleeding in the area of the lower jejunum and ileum were diagnosed only with capsule endoscopy. One ulcer located near the ileocecal valve was then biopsied during a repeat ileocolonoscopy, and the histology showed signs of Crohn's enteritis. The further treatment approach was changed, with medical treatment being initiated a…
In vivo endomicroscopy improves detection of Barrett’s esophagus–related neoplasia: a multicenter international randomized controlled trial
2013
Background Confocal laser endomicroscopy (CLE) enables in vivo microscopic imaging of the GI tract mucosa. However, there are limited data on endoscope-based CLE (eCLE) for imaging Barrett's esophagus (BE). Objective To compare high-definition white-light endoscopy (HDWLE) alone with random biopsy (RB) and HDWLE + eCLE and targeted biopsy (TB) for diagnosis of BE neoplasia. Design Multicenter, randomized, controlled trial. Setting Academic medical centers. Patients Adult patients with BE undergoing routine surveillance or referred for early neoplasia. Intervention Patients were randomized to HDWLE + RB (group 1) or HDWLE + eCLE + TB (group 2). Real-time diagnoses and management plans were r…
Detection of spontaneous echocardiographic contrast within the left atrium by transesophageal echocardiography: spontaneous echocardiographic contrast
1986
Transesophageal echocardiography was performed in 314 patients over a period of 24 months using a 3.5 MHz phased-array system fitted to the distal end of a conventional 12 mm endoscope. In 12 patients (2.6%) transesophageal echocardiography could not be performed because of adverse reaction to the gastroscopic procedure. Side effects were a transient A-V block in one patient and asthmatic attack in another. Mitral valve lesions were found in 99 of 314 patients. In 9 of these 99 patients (11%), including 1 patient with mitral valve stenosis and sinus rhythm, 2 with atrial fibrillation, 3 with disc, and 3 with porcine mitral prosthesis, spontaneous echocardiographic contrast was found within …
Investigation of the Effect of Duodenoscopy on Sphincter of Oddi Manometry
1991
To investigate whether endoscopy affects sphincter of Oddi (SO) manometry, three patients who had undergone previous cholecystectomy and had a T-tube in situ for drainage were studied. Manometry was performed using a perfused triple lumen manometry catheter (diameter 1.7 mm), which was advanced into the SO lumen through the T-tube. SO motility, baseline pressure, common bile duct pressure and duodenal pressure were monitored before and during endoscopy while the tip of the endoscope was in the mouth, esophagus (upper third, precardial), stomach and duodenum. Endoscopy and even a moderate insufflation of air necessary to pass the pylorus and inspect the papilla of Vater did not affect the pa…
Minilaparoscopy versus conventional laparoscopy in the diagnosis of hepatic diseases
2001
Minilaparoscopy (ML) is being used increasingly in the diagnosis of liver disease. This is a prospective study of the accuracy and safety of ML compared with conventional laparoscopy (CL) in the diagnostic workup of liver disease.One hundred four patients with suspected liver disease were randomized either to undergo CL (n = 50) or ML (n = 54). CL was performed with a standard Storz laparoscope (Ø 11 mm, Storz GmbH, Tuttlingen, Germany) according to accepted guidelines. For ML a 1.9-mm small-diameter optical telescope was used (Richard Wolf GmbH, Knittlingen, Germany). In all cases, an attempt was made to obtain a liver biopsy specimen.Laparoscopy could successfully be performed in 100 of 1…
