colectomy

Types

 hemicolectomy

• right hemicolectomy
• left hemicolectomy
• extended hemicolectomy[citation needed]

 sigmoidectomy

• It is a resection of the sigmoid colon, sometimes including part or all of the rectum (proctosigmoidectomy).
• When a sigmoidectomy is followed by terminal colostomy and closure of the rectal stump, it is called a Hartmann operation; this is usually done out of impossibility to perform a "double-barrel" or Mikulicz colostomy, which is preferred because it makes "takedown" (reoperation to restore normal intestinal continuity by means of an anastomosis) considerably easier.[citation needed]

 total colectomy
 total proctocolectomy

• If the rectum is also removed.

 Subtotal colectomy is resection of part of the colon or a resection of all of the colon without complete resection of the rectum.
