Confocal Laser Endomicroscopy: Technical Advances and Clinical Applications

2010

Since its introduction in 2004, confocal laser endomicroscopy (CLE) has emerged as a valuable tool for gastrointestinal endoscopic imaging. Endomicroscopy enables the endoscopist to obtain real time in vivo histology during ongoing endoscopy thereby creating “optical biopsies.” To date, numerous studies have shown potential applications of endomicroscopy in the clinical setting, including in vivo diagnosis of esophageal squamous cell carcinoma, Barrett’s esophagus, celiac disease, and colonic polyps. Moreover, recent data suggest the potential application of endomicroscopy in the field of molecular imaging. Additionally, in recent months new applications and developments in the field of con…

Methylene blue-aided cholangioscopy in patients with biliary strictures: feasibility and outcome analysis

2008

BACKGROUND AND STUDY AIMS: Chromoendoscopy using methylene blue is employed in the gastrointestinal tract to delineate neoplastic lesions. We tested the value of chromoendoscopy during choledochoscopy for characterization of local inflammation, neoplasias, and other alterations in patients with biliary strictures. METHODS: Patients with suspected biliary lesions were scheduled for endoscopic retrograde cholangiography with subsequent cholangioscopy. After initial inspection of the bile duct, 15 ml methylene blue (0.1 %) was administered via the working channel of the cholangioscope. Newly appearing circumscribed or unstained lesions were judged according to their macroscopic type and staini…

Extended pH-monitoring in the evaluation of gastroesophageal reflux in infancy and childhood

1986

Esophageal 24-h pH monitoring was performed in addition to esophagogastrography, esophageal manometry, and esophagoscopy in 66 infants and 12 children from 2–14 years of age with symptoms characteristic of gastroesophageal reflux (GER). In ten infants, ph monitoring was repeated once or twice at intervals of 1 week to 8 1/2 months. The follow-up time for all patients ranged from 2–7 years. Our findings suggest that extended pH monitoring is the most valuable diagnostic procedure under the following circumstances. First, when there are major discrepancies between reported observations and actual symptoms during hospitalization, pH monitoring can clarify the causal relationship. Second, when …

Extracorporeal shock wave lithotripsy of urinary calculi: experience in treatment of 3,278 patients using the Siemens Lithostar and Lithostar Plus.

1991

Between March 1986 and June 1989, 3,278 patients with upper urinary tract calculi were treated at our medical center with the Lithostar lithotriptor. The stones were located in the calices in 41.9% of the cases, renal pelvis in 25.7% and ureter in 32.4%. Perirenal hematoma was noted in 0.5% of the patients but this resolved spontaneously within a few days. Auxiliary procedures were performed in 37.3% of the cases, including Double-J stent and ureteral catheter in 26.8%, ureterorenoscopy in 2.1%, percutaneous nephrostomy in 1.6%, Zeiss loop in 4.3% and percutaneous nephrolithotripsy in 3.5%. Of the treatments 83.1% were performed without general or regional anesthesia. Followup after 3 month…

Rockall Score Larger Than 7 as a Reliable Criterion for the Selection of Indications for Preventive Transarterial Embolization in a Subgroup of High-…

2017

Background Transarterial embolization (TAE) is an alternative procedure to repeat endoscopy or surgical intervention in the case of re-bleeding after primary endoscopic treatment. The aim of the study was to assess the Rockall score as a criterion for TAE in the case of re-bleeding after endoscopic treatment of non-variceal upper gastrointestinal bleeding (NVUGIB). Methods Out of the 673 patients who underwent emergent endoscopic hemostasis due to NVUGIB, 111 had a high risk of re-bleeding having a Forrest I-IIb ulcer and the Rockall score ≥ 5. From 111 patients, 37 accepted preventive TAE (PE+ group). The control group consisted of 74 patients who underwent standard treatment (PE- group). …

Endoluminal sonography in follow-up of rectal carcinoma.

1989

Fourteen patients who had undergone local excision, anterior resection or low anterior resection for rectal carcinoma were examined by endoscopic ultrasonography. In two of three cases of local recurrent carcinomas, endoscopic sonography was superior to computed tomography in determining the depth of tumor infiltration. There were difficulties in differentiating scar tissue from local tumor formation when the mucosa appeared normal upon endoscopic examination. Only repeated follow-up examinations starting in the postoperative period, will allow a differentiation between scar tissue and local tumor recurrence.

Laparoscopic sacrocolpopexy in the treatment of vaginal vault prolapse: 8 years experience

2009

Abstract Objective The aim of this study was to evaluate the long-term results of a laparoscopic sacrocolpopexy for the treatment of vaginal vault prolapse. Study design Between January 1999 and January 2007, 165 laparoscopic sacrocolpopexy procedures, using a polypropylene mesh, were performed on women affected by vaginal vault prolapse. Intraoperative complications included: 5 bladder injuries and 3 sigmoid perforations. Postoperative complications included: 10 cases of fever, 5 cases of lumbosciatica, 15 cases of detrusor overactivity, 2 cases of vaginal haematoma, and 5 cases of minimal dispareunia. At 1, 6 and 12 months after surgery, a clinical evaluation was carried out for all patie…

[Early duodenal adenocarcinoma arising in gastric metaplasia treated by endoscopic resection].

2006

Duodenale Fruhkarzinome sind eine Seltenheit. Die meisten duodenalen Karzinome werden in einem fortgeschrittenen Stadium diagnostiziert. Wir berichten den Fall einer 59-jahrigen Patientin, welche zur weiteren Diagnostik und Therapie eines auswarts diagnostizierten duodenalen Fruhkarzinoms zu uns uberwiesen wurde. Die Osophagogastroduodenoskopie bei Aufnahme ergab eine Typ IIa+c-Lasion im proximalen Duodenum (10 - 12 mm grose zentral diskret eingesenkte Lasion). Mittels Chromo- und Magnifikationsendoskopie konnte die Lasion gut demarkiert und Veranderungen der Zottenarchitektur im Sinne einer Neoplasie gesehen werden. Nach Unterspritzung mit einer verdunnten Adrenalin-Losung konnte die Lasio…

The use of an endostapler in the treatment of supralevator abscess of intersphincteric origin.

2014

Aim This technical note describes the use of an endostapler for the definitive treatment of supralevator abscess upward from an intersphincteric origin. Method A two-stage treatment was performed. First an endoanal drainage was performed by inserting a mushroom catheter in the supralevator abscess cavity. In the second stage transanal unroofing of the fistula was performed with an endostapler. Results Since 2011, three patients have been treated in this way. After 2 years of follow up, none of the patients had recurrence of the abscess or been referred for anal incontinence. Conclusion The use of an endostapler in the treatment of supralevator abscess of intersphincteric origin may be an al…
