      • Plication: Alteration of bowel to relieve obstruction
      • Enterectomy: Resection of damaged or neoplastic segment of bowel
      • Colectomy: Resection of damaged or neoplastic segment of colon
      • Ostomy: Temporary or permanent opening of bowel onto surface of abdomen for feeding or drainage purposes
