Size, differentiation, and stage of colorectal cancer in addition to the interval to diagnosis suggest that the majority of cancers found during surveillance colonoscopy followed prior false-negative examinations. Because cecal landmarks are most constant, prior photographic documentation may help to prove or disprove fast growth of cancers found in the cecum during surveillance colonoscopy.
Intraoperative enteroscopy is a valuable method for localizing gastrointestinal bleeding of obscure origin. The insertion and manipulation of an endoscope through an enterotomy, however, may result in significant trauma to the intestinal wall, as well as contamination of the abdominal cavity. We have devised a new technique for the introduction of the endoscope that lessens trauma to the bowel wall and allows a complete enteroscopy with minimal contamination.
Meckel's diverticulum is the most common congenital anomaly of the small intestine. It is a true diverticulum containing all layers of the intestinal wall and results from the incomplete resolution of the omphalomesenteric duct. The majority of the cases are asymptomatic; however, diagnostic challenges arise when it becomes inflamed, causes gastrointestinal hemorrhage, intestinal obstruction, or when it protrudes through a potential abdominal opening (Littre's hernia). We present a rare case of strangulated Meckel's diverticulum as a result of axial torsion presenting with right lower quadrant abdominal pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
