Endoscopic calcium electroporation for colorectal cancer: a phase I study.

Colorectal cancer is one of the most common malignancies, with approximately 20 % of patients having metastatic disease. Local symptoms from the tumor remain a common issue and affect quality of life. Electroporation is a method to permeabilize cell membranes with high-voltage pulses, allowing increased passage of otherwise poorly permeating substances such as calcium.

ERCP with single-use disposable duodenoscopes in four different set-ups.

Endoscopic retrograde cholangiopancreatography (ERCP) has until now always been performed using a reusable non-sterile duodenoscope. The introduction of the new single-use disposable duodenoscope makes it possible to perform perioperative transgastric and rendezvous ERCP in an almost sterile manner. It also eliminates the risk of patient-to-patient transmission of infection in non-sterile settings.

Electrochemotherapy for colorectal cancer using endoscopic electroporation: a phase 1 clinical study.

 Electrochemotherapy is an anticancer treatment that uses electric pulses to facilitate uptake of chemotherapeutic drugs in tumor cells and has proven to have a high local cytotoxic effect with minimal adverse events. Electrochemotherapy has mostly been used in treatment of cutaneous metastases but development of a new endoscopic electrode device has made treatment of colorectal tumors possible. This first-in-man multicenter phase I study investigated safety and efficacy of electrochemotherapy using endoscopic electroporation in patients with colorectal tumors.

G-EYE colonoscopy is superior to standard colonoscopy for increasing adenoma detection rate: an international randomized controlled trial (with videos).

Background And Aims: Colorectal cancer (CRC) is largely preventable with routine screening and surveillance colonoscopy; however, interval cancers arising from precancerous lesions missed by standard colonoscopy still occur. An increased adenoma detection rate (ADR) has been found to be inversely associated with interval cancers. The G-EYE device includes a reusable balloon integrated at the distal tip of a standard colonoscope, which flattens haustral folds, centralizes the colonoscope's optics, and reduces bowel slippage.

Chronic complaints after simple sutured repair for umbilical or epigastric hernias may be related to recurrence.

Purpose: Umbilical and epigastric hernia repairs are minor, but are commonly conducted surgical procedures. Long-term results have only been sparsely investigated. Our objective was to investigate the risk of chronic complaints after a simple sutured repair for small umbilical and epigastric hernias.

[Novel methods for gastrointestinal endoscopy].

The development of diagnostic and therapeutic flexible endoscopy is vivid. This article describes some of the most recent diagnostic techniques: Narrow Band Imaging, Fujinon Intelligent Color Enhancement, Autofluorescence Imaging, Optical Coherence Tomography, Confocal Laser Endomicroscopy. Literature was found through searches on PUBMED and written information from Olympus, Fujinon and Pentax.
