Video-assisted two-stage basilic vein transposition for creation of brachio-basilic arteriovenous fistulae

2012

We report our experience in a mixed minimally-in- vasive technique for the two-stage transposition of basilic vein on a small series of eight patients. The operative tech- nique consisted of a modified endoscopic (1) approach for the two-stage transposition (2). The intervention was performed under Brachial Plexus Block (3).

Endometrial carcinoma and its precursors: Early detection and treatment

1990

Endometrial carcinoma is the most frequent genital neoplasia in women. Precursors of this condition include endometrial hyperplasia, particularly when cytologic atypia occurs. Among the frequent early clinical manifestations of endometrial carcinoma is abnormal uterine bleeding that must be differentiated from bleeding associated with benign conditions. Early detection of endometrial carcinoma and its precursors in women at risk is the best prophylactic measure in the final therapeutic outcome. In this review, the accuracy of methods of early diagnosis of endometrial carcinoma and its precursors is assessed, in order to provide early therapy and optimum prognosis. The epidemiology of endome…

Long-Segment Early Squamous Cell Carcinoma of the Proximal Esophagus: Curative Treatment and Long-Term Follow-Up after 5-Aminolevulinic Acid (5-ALA)-…

2006

Photodynamic therapy (PDT) is an established treatment for the ablation of dysplastic Barrett's epithelium and early esophageal carcinoma, but no data have been published on curative 5-aminolevulinic acid (5-ALA)-PDT for long-segment early esophageal cancer with infiltration of the upper sphincter. We describe successful curative treatment of an unusual early long-segment squamous cell carcinoma (uT1a,N0) of the proximal esophagus (18 - 28 cm aborally), with three sessions of 5-ALA-PDT. Endoscopic and endosonographic follow-up macroscopically showed a complete remission of the tumor, proven by biopsy showing total histological ablation. After a follow-up period of 23 months, there has been …

Vacuum inversion and securing of distal colonic pseudodiverticula with novel spiked O-rings

2015

Background Diverticular disease is increasingly prevalent in Western societies and is associated with significant morbidity. Objective Two-stage endoscopic device development for inversion and secured ligation of colonic diverticula; first, human cadaver studies were performed to measure forces required for diverticular inversion; second, a novel set of devices (elastic spiked O-ring with delivery system) was tested in animals. Design Prospective, observational study of human cadavers and prospective, interventional study of a porcine model. Setting University hospital pathology laboratory and animal facility. Intervention Full-thickness inversion of the colonic wall with a pipelike deliver…

Prevention of feeding tube dislodgement with the Wiesbaden rein: a case series.

2009

We describe initial experience with the use of a new fixation method (Wiesbaden rein), which has been developed to prevent dislodgement of feeding tubes in the gastrointestinal tract. The Wiesbaden rein has been used in three patients without complication. In none of the patients was dislodgement or malfunction of the feeding tube observed. Therefore, the use of the Wiesbaden rein might prevent dislodgement of feeding tubes. Clinical trials are required before this new method can be recommended for general use.

Chromoendoscopy and Magnifying Endoscopy in Patients with Gastroesophageal Reflux Disease

2004

Gastroesophageal reflux disease (GERD) is common in the Western world. Upper endoscopy is needed to characterize the disease. Barrett’s esophagus as a complication of GERD is an established precancerous condition which can lead to adenocarcinoma in the distal esophagus. This review summarizes recent advances in the endoscopic characterization of Barrett’s esophagus using magnification endoscopy and chromoendoscopy. Methylene blue, indigo carmine and acetic acid are commonly used dyes to facilitate diagnosis of Barrett’s esophagus. Methylene blue is absorbed in the specialized columnar epithelium, which is pathognomonic for Barrett’s esophagus. Indigo carmine and acetic acid are used as cont…

were those plausibly associated with the procedure and severe enough for the patient to seek medical attention. We compared the proportion of patients with adverse events associated with gastrointestinal endoscopy identified with direct patient contact to the proportion identified through our current infrastructure using the chi-square statistic. Results: During the study period, 11,710 endoscopic procedures were performed on 9,683 patients. Our study personnel made 3205 calls over a three month period and ultimately made contact with 1999 (17%; 84.5% of those called) patients. 28 (1.4%) adverse events were identified through direct patient contact. Our adverse event tracking infrastructure…

Direct and oblique approaches to the craniovertebral junction: Nuances of microsurgical and endoscope-assisted techniques along with a review of the …

2017

Purpose: The aim of this review is to provide an update of the technical nuances of microsurgical and endoscopic-assisted approaches to the craniovertebral junction (transnasal, transoral, and transcervical), and to report on the available clinical results in order to identify the best strategy. Methods: A nonsystematic update of the reviews and reporting on the anatomical and clinical results of endoscopic-assisted and microsurgical approaches to the craniovertebral junction (CVJ) was performed. Results: Pure endonasal and cervical endoscopic approaches still have some disadvantages, including their steep learning curves and their deeper surgical fields. Endoscopically assisted transoral s…
