Electrosurgery in Therapeutic Endoscopy
2019, Clinical Gastrointestinal EndoscopyInfluence of the intestinal microbiome on anastomotic healing in the colon and rectum
2018, Seminars in Colon and Rectal SurgeryCitation Excerpt :Even the composition of bacteria was changed, with a significant decrease in Bacilli and Clostridium and an increase in Proteobacteria. The increase in Proteobacteria after lavage can be explained by the introduction of oxygen into the normally anaerobic environment and an increase in pH from the loss of short chain fatty acids.26,27 Given that Proteobacteria (i.e., gram negative bacteria) are often the most pathogenic of the intestinal microbiota, this finding deserves further investigation.
Methods of luminal distention for colonoscopy
2013, Gastrointestinal EndoscopyCitation Excerpt :CO2 absorbed as a result of colonic insufflation is primarily eliminated by an increase in minute ventilation. RCTs of CO2 and air insufflation at colonoscopy by using no sedation,8,36 moderate sedation,37 and deep sedation38,39 that have used either end-tidal or transcutaneous CO2 monitoring have all demonstrated no significant difference in the increase in CO2 levels between the air and CO2 groups. Most studies that used sedation demonstrated a small intraprocedure increase in CO2 levels for both air- and CO2-insufflated patients.8,41,43
Explosion From Argon Cautery During Proctoileoscopy of a Patient With a Colectomy
2012, Clinical Gastroenterology and HepatologyCitation Excerpt :For example, mannitol is no longer used because studies have shown high postpreparation levels of intracolonic hydrogen or methane.9–12 On the other hand, if intracolonic gas samples are measured after air insufflation, in most cases patients did not have increased hydrogen or methane levels, no matter which bowel preparation agent was used.10,11,13–15 Studies that used breath analysis to measure expired gas levels (a surrogate for intracolonic gas levels) generally have not shown high hydrogen or methane levels regardless of the preparation agent used.16,17
Colon explosion during argon plasma coagulation
2008, Gastrointestinal EndoscopyCitation Excerpt :Because further reports on colon explosions after mannitol preparation have been published, new agents, such as polyethylene glycol electrolyte lavage solution and oral sodium phosphate solutions, are now chosen over mannitol preparation.16,17,22,25 It has been shown that these agents are able to decrease the concentrations of combustible gases in the colon.35-38 But mannitol does not appear to be the only sugar compound that may lead to raised combustible gas concentrations in the colon.
