Long-term results after endoscopic drainage of pancreatic pseudocysts: A single-center experience.

Background: Pancreatic pseudocysts (PPC) are collections of fluid encapsulated within a well-defined inflammatory wall that develop during pancreatic inflammation. Internal drainage represents the standard of care in lesions that persist and lead to symptoms and complications. Only limited data are available on long-term results and recurrence of PPC after drainage procedures.

Submucosal injection with waterjet improves endoscopic mucosal resection of colorectal adenoma - a randomised controlled clinical trial.

Purpose: Endoscopic mucosal resection (EMR) of colorectal adenomas leads to a reduced incidence of, and mortality from, colorectal carcinoma. Large adenomas are especially difficult to resect. Submucosal injection is a key part of EMR, as it allows for complete resection and decreased complications.

Use of covered self-expandable stents for benign colorectal disorders in children.

Purpose: There is a lack of experience with covered self-expandable stents for benign colorectal disorders in children.

Methods: Five children (4M, 1F) with a median age of 5years (range, 6months-9years) who underwent treatment with covered self-expandable plastic (SEPSs) or self-expandable metal stents (SEMSs) for a benign colorectal condition between April 2005 and November 2013 were recruited to this retrospective study. Etiologies included: anastomotic stricture with (n=1) or without (n=3) simultaneous enterocutaneous fistula, as well as an anastomotic leak associated with enterocutaneous fistula (n=1).

False teeth in an apple core: Unusual presentation of a colorectal carcinoma.

Introduction: Ingestion of foreign bodies is common amongst the elderly. Although most foreign bodies pass through the gastrointestinal tract without consequence some cause complications including bowel perforation.

Presentation Of Case: We present a case of denture ingestion that lead to the diagnosis of an unsuspected colorectal cancer.

Improved Techniques for Endoscopic Mucosal Resection (EMR) in Colorectal Adenoma.

Background: Endoscopic therapy of colorectal adenomas and early cancers is a standard method. Besides oncological criteria, the method is limited by polyp location, size, and texture.

Method: Based on the current literature, technical modifications and developments in endoscopic mucosal resection are described.

Differences in the endoscopic closure of colonic perforation due to diagnostic or therapeutic colonoscopy.

Objective: To describe the experience of a single center regarding the feasibility of endoscopic closure of iatrogenic colonic perforations and to elucidate differences between the efficacy of endoscopic clip closure due to diagnostic or therapeutic colonoscopy.

Material And Methods: A retrospective institutional computer-based search of records of colonoscopic perforation occurring between January 2004 and December 2011 was undertaken. Data on patients undergoing colonoscopy were entered into a clinical database.

Combination of water-jet dissection and needle-knife as a hybrid knife simplifies endoscopic submucosal dissection.

Background: The safety and efficacy of endoscopic submucosal dissection (ESD) is very dependent on an effective injection beneath the submucosal lamina and on a controlled cutting technique. After our study group demonstrated the efficacy of the HydroJet in needleless submucosal injections under various physical conditions to create a submucosal fluid cushion (Selective tissue elevation by pressure = STEP technique), the next step was to develop a new instrument to combine the capabilities of an IT-Knife with a high-pressure water-jet in a single instrument. In this experimental study, we compared this new instrument with a standard ESD technique.

Selective tissue elevation by pressure injection (STEP) facilitates endoscopic mucosal resection (EMR).

Endoscopic mucosal resection and endoscopic submucosal dissection have become more common in treatment of flat superficial tumors of the gastrointestinal tract. Submucosal injection is used to try to avoid complications and improve the technical feasibility of the procedure. However, the method has its limitations, particularly when treating extensive flat tumors in the colon.
