Tube-in-tube endoscopic vacuum therapy for treatment of colorectal anastomotic leaks: A low-cost, patient-friendly, feasible and efficient technical modification of sponge-based endoscopic vacuum therapy.

Background And Aims: Colorectal endoscopic vacuum therapy (CR EVT) is usually performed using sponges passed through the anus. It may be associated with patient discomfort and displacement of the aspiration tube.

Methods: With the tube-in-tube endoscopic vacuum therapy modification (CR TT-EVT), it is possible to position the aspiration tube in the pelvic cavity through the abdominal wall.

Association between mucosal surface pattern under near focus technology and infection.

Background: Many studies evaluated magnification endoscopy (ME) to correlate changes on the gastric mucosal surface with () infection. However, few studies validated these concepts with high-definition endoscopy without ME.

Aim: To access the association between mucosal surface pattern under near focus technology and infection status in a western population.

ENDOSCOPIC EVALUATION OF POST-FUNDOPLICATION ANATOMY AND CORRELATION WITH SYMPTOMATOLOGY.

Background: Endoscopic aspect of fundoplication anatomy: Normal aspect of Nissen fundoplication. Upper digestive endoscopy is important for the evaluation of patients submitted to fundoplication, especially to elucidate postoperative symptoms. However, endoscopic assessment of fundoplication anatomy and its complications is poorly standardized among endoscopists, which leads to inadequate agreement.

Upper gastrointestinal endoscopy applied in pediatrics: endoscopic and histological findings, including Helicobacter pylori.

Objective: To present and discuss the endoscopic and histological results, as well as the incidence of Helicobacter pylori and other diseases, indications and characteristics of upper digestive endoscopies performed in children.

Material And Methods: Twenty-five endoscopies were performed in children aged six months to 11 years (mean 7.69 years), from February 2013 to January 2016.

Papillary fistulotomy conventional cannulation for endoscopic biliary access: A prospective randomized trial.

Aim: To compare the cannulation success, biochemical profile, and complications of the papillary fistulotomy technique catheter and guidewire standard access.

Methods: From July 2010 to May 2017, patients were prospectively randomized into two groups: Cannulation with a catheter and guidewire (Group I) and papillary fistulotomy (Group II). Amylase, lipase and C-reactive protein at T0, as well as 12 h and 24 h after endoscopic retrograde cholangiopancreatography, and complications (pancreatitis, bleeding, perforation) were recorded.

Modified technique for percutaneous endoscopic gastrojejunostomy placement.

The placement of percutaneous endoscopic gastrojejunostomy (PEG-J) provides diet delivery beyond the angle of Treitz, and it is associated with decrease of complications related to gastroparesis, such as aspiration pneumonia. There are many different techniques to perform a PEG-J described in the literature, with variable degrees of technical success. In this article, we suggest modifications to the technique of PEG-J placement in order to reduce time of procedure and minimize the risk of technical failure.

ERCP using double-balloon enteroscopy in patients with Roux-en-Y anatomy.

Double-balloon enteroscopy (DBE) is a useful method for endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anatomy. Depending on the distorted anatomy, endoscopic therapies with conventional scopes were very difficult or impossible before the advent of DBE and patients had to be submitted to a percutaneous or surgical approach. The case of 6 patients with different types of Roux-en-Y-altered anatomy in which DBE-ERCP was performed with 83.
