Surveillance of FAP: a prospective blinded comparison of capsule endoscopy and other GI imaging to detect small bowel polyps

Background: Familial adenomatous polyposis (FAP) is a hereditary disorder characterized by polyposis along the gastrointestinal tract. Information on adenoma status below the duodenum has previously been restricted due to its inaccessibility in vivo. Ca

Comparison of oral lavage methods for preoperative colonic cleansing

Polyethylene glycol electrolyte lavage solution was compared with a 10 percent mannitol solution for preoperative colonic cleansing. Eighty patients were prepared randomly with one of these solutions on the afternoon prior to surgery. Colonic cleansing was better with polyethylene glycol electrolyte lavage (90 percent optimal cleansing vs. 75 percent). Analysis of hematologic, biochemical, and weight changes before and after the bowel preparation, demonstrated a mild subclinical dehydration with the use of mannitol. Evaluation of patient tolerance demonstrated more nausea, cramps, and abdominal pain with mannitol. Other symptoms were similar with both preparations. Colonic hydrogen gas was sampled during surgery, and two patients in the mannitol group had combustible levels. This study confirms that both 10 percent mannitol and polyethylene glycol electrolyte lavage are safe, effective methods of preoperative bowel cleansing. Better cleansing, patient tolerance, and lower hydrogen gas level make polyethylene glycol electrolyte lavage the preferred method
