General Surgery
Sigmoidectomy
Sigmoidectomy is a surgery done by the removal of the
sigmoid colon and indicated to treat cancer of the sigmoid colon; sigmoid
volvulus; large cysts of the sigmoid; prolapse of the rectum; inflammatory
bowel diseases(ulcerative colitis and Crohn disease); benign tumors of the
sigmoid colon; fistula between the bladder and sigmoid colon; and
scleroderma of the colon. Before sigmoidectomy procedure can begin, the
individual is given general anesthesia. The patients lower abdomen is shaved
and washed with soap and antiseptic, and draped so that only the area
between the pubis and navel is exposed. A vertical incision is performed
between the pubis and the navel; some doctors prefer a horizontal incision
along a line just above the pubis. The muscles, fascia, skin are cut in
layers and bleeding vessels are cauterized or ligated. The sigmoid colon is
found and freed from its supporting structures by blunt and scalpel
dissection. After the diseased part of the sigmoid has been freed, it is
clamped at both ends and cut between the 2 clamps. The removed part is sent
for examination to the pathologist. The different layers over the colon,
such as fascia, skin, and muscle are closed with sutures. In some cases
staples may also be used. The person is transferred to the recovery room.
Most individuals will have a nasogastric tube (a tube that is inserted
through nose and runs down to the stomach) for the first few days after the
sigmoidectomy to keep the body regular secretion of gastric juices out of
the lower intestine. The tube is usually taken out, when it is clear that
the bowel is working again and the internal connections have had time to
heal. The person is started on a liquid diet and gradually returned to solid
food.
