The length dependence of the spontaneous contractile activity of human colonic muscle was assessed in vitro. Muscle obtained from the right colon was more distensible than that of the left colon. This was true for all muscle layers. Maximum spontaneous active stress was exerted by both circular and longitudinal muscle layers of the right colon at greater degrees of stretch (p less than 0.001) t...

AIM Tumours of the right and left colon are suggested to be different entities with different prognosis. The aim was to explore differences related to the location of a colonic tumour. PATIENTS AND METHODS A single-centre retrospective analysis of all patients treated for colon cancer during 1999-2008 (n=1558) was carried out. Assessed data included demography, pathology and survival by cance...

BACKGROUND Incidence rates of colorectal cancer (CRC) in New Zealand rank among the highest worldwide. Internationally, there has been evidence of a shift in colon cancer from left- to right-sided. The objective of this study was to determine trends in left- and right-sided colon and rectal cancers incidence by sex, age and ethnicity. METHODS Using datasets created by linking data from the Ne...

BACKGROUND We evaluated the clinicopathologic features and outcomes of Taiwanese patients with right-sided versus left-sided colon cancer according to various cancer stages. METHODS A total of 1095 patients with primary colorectal cancer (CRC) undergoing surgery at a single-institution were enrolled. We analyzed patient differences in terms of clinicopathologic features, overall survival (OS)...

Congenital anomalies such as positional anomalies of the right half of the colon are more common when compared to its left half. We report a rare case of congenital anomaly where the transverse colon was totally absent. Ascending colon continued as descending colon at the right colic flexure. Ascending and descending colons formed an inverted U shaped loop which was situated in the right half o...

Ultrasound is essential for differential diagnosis in patients with left lower quadrant (LLQ) abdominal pain. Causes of LLQ pain are variable such as diverticulitis, colitis, appendagitis, and rarely appendicitis (in situs inversus). Colon cancer also an occasional cause. findings colon irregular wall thickening loss stratification luminal narrowing. We report a case descending hepatic metastas...
