Background: Based on sound evidence, traditional mechanical bowel preparation for elective colorectal surgery has mostly been abandoned during the last two decades. However, more recent evidence from USA large databases show that mechanical bowel preparation combined with oral antibiotics, reduces significantly surgical site infections (SSI) after elective colorectal surgery. Hypothesis-Aim: We...
Optimal bowel preparation is essential for the safety and outcome of colonoscopy. A solution containing polyethylene glycol (PEG) is often used as a bowel cleansing agent, but some patients are intolerant of PEG, and this may lead to discontinuation of colonoscopy. Sodium phosphates (NaP) tablets are designed to improve patient acceptance and compliance. The objective of this study was to compa...
BACKGROUND The value of the preparation of the colon prior colorectal surgery remains debatable. Since installed as traditional the use of this routine, few studies have been conducted to support the safety of surgeries done without mechanical bowel preparation. AIM To determine if there is a correlation between postoperative complications and no use of mechanical bowel preparation in operate...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Human jejunum smooth muscle cells (SMCs) and interstitial cells of Cajal (ICCs) express the SCN5A-encoded voltage-gated, mechanosensitive sodium channel NaV1.5. NaV1.5 contributes to small bowel excitability, and NaV1.5 inhibitor ranolazine produces constipation by an unknown mechanism. We aimed to determine the presence and molecular identity of Na(+) current in the human colon smooth muscle a...
GOALS To test the hypothesis that the use of a low-residue breakfast (LRB) the day prior to colonoscopy was not inferior to consuming clear fluids alone (CFD) in patients undergoing outpatient colonoscopy with a polyethylene glycol (PEG) bowel preparation. BACKGROUND Optimal colon cleansing is essential for complete visualisation of the mucosa during colonoscopy. Few studies have examined the...
Purpose: To use gene transcript profiling to identify cancer-associated gene expression. Experimental Design: Methods included (i) marker discovery using laser capture microdissection (LCM)-assisted specimen preparation and antisense RNA-long serial analysis of gene expression (aRNALongSAGE) on matched colon cancer and uninvolved colon tissue specimens (n 1⁄4 5). Candidate tumorassociated genes...
