Definition Colectomy is the surgical removal of all or a part of the colon, the primary a part of the enormous intestine.


Cause doctors participate in colectomy to remove massive Stage I colon melanoma lesions or to remedy colon cancer that: has unfold beyond the mucous membrane, has infiltrated or spread beyond the intestinal wall, or is more likely to recur. Medical professionals also participate in this system to strengthen patients’ first-rate of lifestyles by using relieving suffering and stopping bleeding and other symptoms that occur when colon melanoma invades organs close the bowel, and likewise, when nonsurgical approaches are unsuccessful, to treat diverticulitis, ulcerative colitis, and benign colon polyps.


Precautions This surgical procedure can drastically cut down bowel manage and sexual operate.


Description Colectomy is the desired medication for colon cancers that may be cured. Carried out in a clinic, underneath general anesthesia, this approach entails doing away with the cancerous part of the colon, a margin of typical bowel, and any tissue or lymph nodes littered with the sickness, and reconnecting the healthy segments of the colon (anastomosis). If illness or obstruction make it unattainable to reconnect the colon, the health care professional creates an opening (stoma) in the abdominal wall (colostomy) by means of which feces passes from the physique into a disposable assortment bag. Colostomy is also: • temporary, with the ends of the intestines being recon- nected at a later time, or • everlasting in patients whose cancer can’t be com- pletely eliminated.


Open and laparoscopic methods common, or open, colectomy is an invasive proce- dure requiring a extensive surgical incision. This surgical procedure makes it possible for the general practitioner to view the interior organs very clearly. Laparoscopic colectomy requires just a few small incisions, allows for medical professionals to view the inner organs, and outcome in a shorter sanatorium keep and fewer aspect results. Experiences advise that laparoscopic colectomy could also be safer than open surgical procedure for elderly patients. A scientific trial funded via the national Institutes of well being (NIH) is evaluating survival charges for the 2 methods.


Varieties of colectomy LEFT RADICAL HEMICOLECTOMY. Medical professionals participate in left radical hemicolectomy to eliminate cancer and other irregular tissue within the: • descending colon, which extends from the pelvis to the spleen, • and splenic flexure, the location the place the descending colon joins the a part of the significant intestine that extends throughout the center of the stomach (transverse colon). When melanoma is found in the splenic flexure, the general practitioner eliminates the splenic flexure, the first half of of the descending colon, and about one-third of the transverse colon.


Correct RADICAL HEMICOLECTOMY. Medical professionals participate in this procedure to do away with tumors and different abnormalities of the: • component to giant intestine nearest the appendix (cecum) • element of the colossal gut that extends along the correct aspect of the physique from the small intestine to the transverse colon (ascending colon). This procedure includes taking out the cecum, descending colon, the hepatic flexure the place the ascending colon joins the transverse colon, and the primary onethird of the transverse colon. These strategies are considered radical considering that they involve disposing of nerves, blood vessels, and lymph nodes close the tumor.


TRANSVERSE COLECTOMY. Carried out to do away with disorder within the transverse colon, this system includes casting off the: • transverse colon, • and hepatic and splenic flexures. SIGMOID RESECTION. Used to get rid of cancer in the a part of the colon (sigmoid) between the descending colon and rectum, this system entails taking away the: • sigmoid colon • backside two-thirds of the descending colon


RECTOSIGMOID RESECTION. Used to get rid of tumors within the part of the colon (rectosigmoid) just above the rectum (sigmoid flexure), this procedure removes: • the sigmoid colon • most of the rectum and surrounding rectal tissue (mesorectum) in view that tumors in this part of the colon commonly involve the bladder, uterus, or other organs, the general practitioner may just insert drainage tubes or a catheter to draw urine from the bladder.


ABDOMINOPERINEAL RESECTION (APR). This extensive approach, which is also performed in two elements or by way of two surgical groups operating whilst, entails doing away with the: •slash sigmoid colon •rectum • anus • neighborhood lymph nodes, blood vessels, and nerves Sphincter-saving APR is designed to lower lack of bowel manipulate via: • taking away only the tumor • maintaining nerves and blood vessels close the tumor. These specialized strategies contain repositioning the tumor at the same time eliminating it, can cause shedding of tumor cells, and might not be to be had in all hospitals. After finishing any of these tactics, the health care provider makes use of: • sutures • clips • heat and electrical present (electrothermal bipolar ves- sel sealer) to tie off the ends of blood vessels before closing the incision.


Coaching The day before the operation, the sufferer may just eat only clear drinks, and could take nothing by means of mouth after midnight. To decrease the probability of infection, antibiotics are given to the sufferer the night earlier than the operation.


Aftercare A sufferer who has had an open colectomy will spend at least a week in the medical institution and experience giant postoperative soreness. A patient who has had a laparoscopic colectomy will spend 4–5 days within the hospital, expertise much less affliction, and resume normal activities within two weeks. A patient who has had a colostomy have to learn to maintain the collection bag and hold the field clean. Patients who have had colostomies typically fear about: • no longer being equipped to take care of themselves • odors, gas, and leakage from the collection bag • wellbeing problems •recurrence of melanoma A patient who’s depressed about sexual dysfunction, bowel issues, or different aspects of cure may improvement from professional counseling or from becoming a member of a support workforce.


Risks aspect results of colectomy comprise bladder issues, diarrhea,bowel irregularities, urinary urgency, and sexual dysfunction.


Traditional outcome Most patients experience postoperative pain. Sufferers who have laparoscopic surgery have much less soreness than patients who’ve open colectomy. Some sufferers require temporary colostomy except usual bowel function returns. Some of these procedures don’t impact sexual function, but rectosigmoid resection could make it intricate for a man to gain erection for the period of intercourse.
