Localised folate deficiency has been implicated in colonic carcinogenesis and supplementation has been proposed for certain populations at risk. However, identifying those groups that may benefit is difficult as the relation between blood folate and gut epithelial cell values is unknown. The aim of this study was to define this relation. Epithelial cells mean (SEM) (sigmoid: 5.35 (0.56) x 10(6)...
Background Sigmoid volvulus (SV) in pregnancy is a very rare entity, which can be associated with extremely high rates of mortality and morbidity for both mother and fetus. Care Report A 22-year-old female patient with a first pregnancy with a gestational age of 27 weeks was referred to the Omolbanin hospital, Mashhad, Iran, ...
A new sigmoid growth equation is presented for curve-fitting, analysis and simulation of growth curves. Like the logistic growth equation, it increases monotonically, with both upper and lower asymptotes. Like the Richards growth equation, it can have its maximum slope at any value between its minimum and maximum. The new sigmoid equation is unique because it always tends towards exponential gr...
Among women with intestinal endometriosis, the sigmoid colon and rectum are the most commonly involved areas. Sometimes, the differential diagnosis of colorectal endometriosis from carcinoma of the colon and rectum is difficult due to similar colonoscopic and radiologic findings. From October 2002 to September 2007, we performed five operations with curative intent for rectal and sigmoid colon ...
Post-traumatic colonic stenosis (obstruction) is rare. We experienced a case of sigmoid obstruction due to blunt abdominal trauma. A 75-year-old man was hit on the lower abdomen 3 days before admission and gradually developed abdominal pain and distension. Laboratory data showed severe inflammation and a barium enema disclosed obstruction of the sigmoid colon. Conservative treatment was careful...
1 of 2 DESCRIPTION A 87-year-old gentleman presented as an acute admission with abdominal distension and inability to open his bowels for the preceding 4 days. His co-morbidities included Down’s syndrome, moderate learning disabilities, osteoarthritis and hypertension. He was known to suffer from recurrent sigmoid volvulus which was extensively investigated. Colonoscopy did not reveal any intra...
The ileo-sigmoid knot is a rare surgical entity, corresponding to the wrapping of ileum around base sigmoid colon forming knot.An associated condition with rapid progression intestinal gangrene and high mortality. It cause obstruction especially during pregnancy. We report here case patient at 13 weeks amenorrhea an diagnosed late stage fetal loss.
To investigate the reason why, during a mass contraction, the stool moving from the colon to the sigmoid colon stops short of the rectosigmoid junction (RSJ) instead of passing directly to the rectum, and whether the sigmoid colon and RSJ share in the anorectal continent mechanism, 12 mongrel dogs were studied. Under anesthesia, the anorectum was excised, sigmoid colon and RSJ were mobilized an...
Sigmoid volvulus complicating pregnancy is a rare, non-obstetric cause of abdominal pain that requires prompt surgical intervention (decompression) to avoid intestinal ischemia and perforation. We report the case of a 31-week pregnant woman with abdominal pain and subsequent development of constipation. Preoperative diagnosis was achieved using magnetic resonance imaging and ultrasonography: th...
Colouterine fistula is an extremely rare condition because the uterus is a thick, muscular organ. Here, we present a case of a colouterine fistula secondary to colonic diverticulitis. An 81-year-old woman was referred to the emergency department with abdominal pain and vaginal discharge. Computed tomography showed a myometrial abscess cavity in the uterus adherent to the thick sigmoid wall. Upo...
