Before removal, the portion of the bowel to be resected must be freed or mobilized. This is done by dissection and removal of the mesentery and other peritoneal attachments. Resection of any part of the colon entails mobilization and the cutting and sealing, or ligation, of the blood vessels supplying the portion of the colon to be removed. [8]
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]
While the first part of the large intestine is responsible for the absorption of water and other substances from the chyme, the main function of the descending colon is to store waste until it can be removed from the body in solid form, when a person has a bowel movement. The stools gradually solidify as they move along into the descending ...
Proctocolectomy is the surgical removal of the entire colon and rectum from the human body, leaving the patients small intestine disconnected from their anus. [1] It is a major surgery that is performed by colorectal surgeons, however some portions of the surgery, specifically the colectomy (removal of the colon) may be performed by general surgeons. [2]
The signs and symptoms of colorectal cancer depend on the location of the tumor in the bowel, and whether it has spread elsewhere in the body ().The classic warning signs include: worsening constipation, blood in the stool, decrease in stool caliber (thickness), loss of appetite, loss of weight, and nausea or vomiting in someone over 50 years old.

Postcholecystectomy syndrome (PCS) describes the presence of abdominal symptoms after a cholecystectomy (gallbladder removal). Symptoms occur in about 5 to 40 percent of patients who undergo cholecystectomy, [1] and can be transient, persistent or lifelong. [2] [3] The chronic condition is diagnosed in approximately 10% of postcholecystectomy ...
Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. [1] The field is also known as proctology, but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular.
Treatment consists of intravenous fluids, antibiotics, and avoiding oral intake of food, water, etc. until symptoms improve. Risk factors include right colon polypectomy, large polyp size (>2 cm), non-polypoid lesions (laterally spreading lesions), and hypertension. [47] Although rare, infections of the colon are a potential colonoscopy risk.
