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.

The most common of these procedures are removal of all or part of the colon , or removal of the kidney (nephrectomy). Some surgeons perform these procedures completely laparoscopically, making the larger incision toward the end of the procedure for specimen removal, or, in the case of a colectomy, to also prepare the remaining healthy bowel to ...
Colectomy (col-+ -ectomy) is the surgical removal of any extent of the colon, the longest portion of the large bowel. Colectomy may be performed for prophylactic, curative, or palliative reasons. Colectomy may be performed for prophylactic, curative, or palliative reasons.
The colon is then mobilized from the retroperitoneum. Care is taken to avoid injury to the ureters and duodenum. The surgery then follows the same steps as small bowel resection. However, due to the colon's placement in the retroperitoneum, more dissection is often required to allow for tension free anastomosis. [5] [6]
Removal of large parts of the colon can lead to loss of electrolytes. Similarly, calculated measurements of renal function (such as the Cockcroft-Gault formula ) are unlikely to reflect actual activity of the kidney , as these calculations were developed for patients in whom the circulatory system correlates with the body weight; this relation ...
The cranial portion of the loop will develop into the jejunum and most of the ileum, while the caudal part of the loop eventually forms the terminal portion of the ileum, the ascending colon and the initial two-thirds of the transverse colon. As the foetus grows larger, the mid-gut loop is drawn back through the umbilicus and undergoes a ...
The same instrument used for sigmoidoscopy performs the colonoscopy. A colonoscopy permits a comprehensive examination of the entire colon, which is typically around 1,200 to 1,500 millimeters in length. [6] In contrast, a sigmoidoscopy allows for the examination of only the distal portion of the colon, which spans approximately 600 millimeters ...
