  • What is Diagnosis?(1) Dilated Colon >6cm(2) Effacement of Haustrae Peripherally located(3) Multiple Air Fluid LevelsLarge Bowel Obstruction
  •  IV & IVFs Analgesics & Antiemetics NG decompression Antibiotics for Gram (-) Aerobes & Anaerobes (ie. Flagyl, Cipro, Zosyn, Clindamycin) Surgery Consult Admission for all LBO Emergency Laparotomy if:  (1) Peritonitis (2) Peritoneal Free Air (3) Sepsis (4) Cecal Distention >12cm
  •  How to Differentiate Large from Small Bowel Obstruction: Gas in the Large Bowel is usually situated peripherally.  Gas in the small bowel is usually centrally located. Large intestine has haustrae, which are blunter, thicker, and do not completely transverse intestine.  Small Intestine has valvulae conniventes that transverse width of intestine, giving it a ribbed appearance. Feces are only found in Large Intestine.
  •  Rule of 3,6,9:  suspect obstruction if small bowel dilated >3cm; large bowel >6cm, cecum >9cm. Causes of LBO:  Carcinoma (60%), Diverticulitis (20%), Volvulus (10%)
