The Hartmann's procedure with a proximal end colostomy or ileostomy is the most common operation carried out by general surgeons for management of malignant obstruction of the distal colon. During this procedure, the lesion is removed, the distal bowel closed intraperitoneally, and the proximal bowel diverted with a stoma.
A ureterosigmoidostomy is a surgical procedure wherein the ureters, which carry urine from the kidneys, are diverted into the sigmoid colon.It is performed as a secondary treatment in bladder cancer patients who have undergone cystectomy.
APRs involves removal of the anus, the rectum and part of the sigmoid colon along with the associated (regional) lymph nodes, through incisions made in the abdomen and perineum. The end of the remaining sigmoid colon is brought out permanently as an opening, called a stoma , which is used by the patient in conjunction with a colostomy pouch, on ...
The sigmoid colon is completely surrounded by peritoneum (and thus is not retroperitoneal), which forms a mesentery (sigmoid mesocolon), which diminishes in length from the center toward the ends of the loop, where it disappears, so that the loop is fixed at its junctions with the iliac colon and rectum, but enjoys a considerable range of movement in its central portion.

The transverse colon is usually less than 6 cm in diameter. [4] A megacolon can be either acute or ...
