1. Loading the sigmoid colon with warm water and warm water irrigation for dealing with spasm (Study Treatment) will significantly reduce the proportion of patients complaining of abdominal discomfort compared with no water loading and waiting for spasms to subside (Control Treatment). The median discomfort score reported by the patients will be significantly lower in the group receiving the Study Treatment than the group receiving Control Treatment. Hypothesis
2. Exploratory hypothesis: There are differences in secondary outcome variables when patients managed by the Study and Control Treatments are compared. Co-variables affect the primary and secondary outcome variables.
The purpose of the study is to conduct a RCT study to determine the effectiveness of loading the sigmoid colon with warm water and warm water irrigation for dealing with colonic spasms in enhancing patient abdominal comfort during unsedated colonoscopy. The specific aim is to compare Study Treatment of warm water loading and irrigation when spasms occur with Control Treatment of no water loading and waiting for spasms to subside. The proportion of patients complaining of abdominal discomfort and their discomfort score are the primary outcome variables. The secondary outcome variables and co-variables described below will be recorded in a prospective manner to ensure completeness of data collection. In preliminary clinical observation at VA Sepulveda ACC, 25 to 30% of VA patients accept colonoscopy without sedation. The goal of this study is to find ways of further reducing discomfort associated with unsedated colonoscopy.

This is a study to compare two different, but normally, used methods of colonoscopy in patients that require a routine or repeat colonoscopy. There will be three arms in this study: WE wat...
Screening colonoscopy is considered the gold standard for adenoma detection in the colon. However, it has been shown that a considerable number of polyps can be missed during screening col...
Given the limited existing data regarding the advantages and limitations of the existing techniques in the removal of colonic polyps the investigators designed a prospective study in order...
Several novel imaging technologies are currently used for detection and differentiation of colonic polyps during colonoscopy, such as NBI (Olympus), FICE (Fujinon), and i-Scan (Pentax). ...
The effects of coffee have been shown to act as a colonic stimulant. Caffeinated coffee stimulates colonic activity, most notably in the transverse/descending colon, in magnitude similar t...
Endoscopic mucosal resection comprises the first-line treatment for large cecal polyps. With up to 14% of unresectable colonic polyps harboring malignancy, the management of endoscopically unresectabl...
Approximately 0.6% to 4% of cholecystectomies are performed because of gallbladder polyps. The decision to perform cholecystectomy is based on presence of gallbladder polyp(s) on transabdominal ultras...

The aim of this study is to investigate the relationship between () gene mutations and nasal polyps. Genomic DNA was extract from 48 nasal polyps tissues, and 30 samples of inferior turbinate tissues ...
The present study investigated whether increasing morning rectal temperatures (T) to evening levels, or increasing morning and evening Tto an "optimal" level (38.5°C), resulting in increased muscle t...
Discrete tissue masses that protrude into the lumen of the COLON. These POLYPS are connected to the wall of the colon either by a stalk, pedunculus, or by a broad base.
A condition of the feet produced by prolonged exposure of the feet to water. Exposure for 48 hours or more to warm water causes tropical immersion foot or warm-water immersion foot common in Vietnam where troops were exposed to prolonged or repeated wading in paddy fields or streams. Trench foot results from prolonged exposure to cold, without actual freezing. It was common in trench warfare during World War I, when soldiers stood, sometimes for hours, in trenches with a few inches of cold water in them. (Andrews' Diseases of the Skin, 8th ed, p27)
The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
Gram-negative aerobic rods found in warm water (40-79 degrees C) such as hot springs, hot water tanks, and thermally polluted rivers.
A variant of ADENOMATOUS POLYPOSIS COLI caused by mutation in the APC gene (GENES, APC) on CHROMOSOME 5. It is characterized by not only the presence of multiple colonic polyposis but also extracolonic ADENOMATOUS POLYPS in the UPPER GASTROINTESTINAL TRACT; the EYE; the SKIN; the SKULL; and the FACIAL BONES; as well as malignancy in organs other than the GI tract.
