General Surgery Basics

Definitions

  • Laparotomy: opening up to abdomen
  • Laparoscopy: performing keyhole surgery on the abdomen
  • Adhesions: scar tissue in the abdomen that attach its contents together (like spiderman’s webs)
  • Volvulus: twisting of the colon
  • Tenesmus: symptoms of full rectum/needing to open bowels after having emptied bowels
  • Hemicolectomy: removing a portion of the bowel
  • Hartmann’s procedure: removing rectum and/or sigmoid colon and forming a colostomy

 

There are three main causes of intestinal adhesions: previous surgery, peritonitis and intra-abdominal infection. Rarely radiotherapy and congenital adhesions.
