INTRODUCTION: Sacrectomy to treat malignant tumors is often results in large pelvic defects to require reconstruction, using a prosthetic mesh. Importance is to avoid its direct contact of mesh with intestine to prevent adhesion between them. PRESENTATION OF CASE: An 83-year old woman who was diagnosed with a mesh infection caused by a small bowel penetration 10 years after sacrectomy combined with mesh reconstruction for chordoma. In the first operation, because of incomplete re-peritonealization due to a large defect in the retroperitoneum, a mesh unavoidably was compelled to contact with the small intestine...

Pedro Boal Carvalho, José Cotter
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of remission and periods of relapse. Patients often present with symptoms such as rectal bleeding, diarrhea and weight loss, and may require hospitalization and even colectomy. Long-term complications of UC include decreased quality of life and productivity and an increased risk of colorectal cancer. Mucosal healing (MH) has gained progressive importance in the management of UC patients. In this article, we review the endoscopic findings that define both mucosal injury and MH, and the strengths and limitations of the scoring systems currently available in clinical practice...

BACKGROUND AND AIMS: Small bowel submucosal lesions (SBSL) and innocent bulges may have an identical appearance and be difficult to distinguish on small bowel capsule endoscopy (SBCE). Recently, Pirelli et al. proposed a score, smooth, protruding lesion index on capsule endoscopy (SPICE), in order to differentiate between the two. We aimed to evaluate and validate SPICE as a differentiation method between innocent bulges and SBSLs. METHODS: We evaluated all SBCEs performed in our department between January 2005 and September 2015, and selected the ones with a smooth, round, protruding lesion in the small bowel...

Redox signaling regulates physiological self-renewal, proliferation, migration and differentiation in gastrointestinal epithelium by modulating Wnt/β-catenin and Notch signaling pathways mainly through NADPH oxidases (NOXs). In the intestine, intracellular and extracellular thiol redox status modulates the proliferative potential of epithelial cells. Furthermore, commensal bacteria contribute to intestine epithelial homeostasis through NOX1- and dual oxidase 2-derived reactive oxygen species (ROS). The loss of redox homeostasis is involved in the pathogenesis and development of a wide diversity of gastrointestinal disorders, such as Barrett's esophagus, esophageal adenocarcinoma, peptic ulcer, gastric cancer, ischemic intestinal injury, celiac disease, inflammatory bowel disease and colorectal cancer...

INTRODUCTION: Single-port laparoscopic surgery (SPLS) has gained popularity due to its cosmetic benefit, and therefore, has been applied to several kinds of benign operations, such as appendectomy and cholecystectomy. The safety and suitability of SPLS for colon cancer has not been widely proved. We aimed at validating the safety, efficacy, and short-term quality of life (QOL) of SPLS compared with conventional laparoscopic surgery (CLS) in patients with colon cancer. MATERIALS AND METHODS: Between June 2010 and April 2011, a total of 62 patients with pathology-proven colon cancer were randomly allocated to two groups: SPLS and CLS...

GOAL: The aim of our prospective study was to analyze the results of endoscopic stenting to treat obstruction due to colorectal cancer and complications after colorectal resection for cancer. BACKGROUND: Endoscopic stenting for obstructing colorectal cancer has become a common place in clinical practice. However, there is a 2% to 5% risk of bowel perforation, and a percentage of technical failure of 2% to 10%. MATERIALS AND METHODS: In a 15-year period (August, 1999 to December, 2013), 153 patients with colorectal cancer had endoscopic placement of a self-expandable metal stent for treatment of an obstructing colorectal cancer (133 patients) or for treatment of complications after colorectal resection for cancer (20 patients)...

PURPOSE: VMAT treatment planning for large pelvic volume irradiation could be suboptimal due to inability of Varian linac to split MLC carriage during VMAT delivery for fields larger than 14.5cm in X direction (direction of leaf motion). We compare the dosimetry between 3 VMAT planning techniques, two 2-arc field techniques and a 3-arc field technique: a) two small in X direction (less than 14.5cm) arc fields, complementing each other to cover the whole lateral extent of target during gantry rotation, b) two large arc fields, each covering the targets completely during the rotation, c) a 3 field technique with 2 small in X direction arcs and 1 large field covering whole target...

PURPOSE: Pancreatic SBRT is uniquely challenging due to both the erratic/unstable motion of the pancreas and the close proximity of the radiosensitive small bowel. Respiratory gating can mitigate this effect, but the irregularity of motion severely affects traditional phase-based gating. The purpose of this study was to analyze real-time motion data of pancreatic tumors to optimize the efficacy and accuracy of respiratory gating, with the overall goal of enabling dose escalated pancreatic SBRT...
