```
ABX not usually requried in simple cases
71
hemorrhohids
Conservative = high fiber diet, increased fluids, warm Sitz baths & topical rectal corticosteroids & analgesics to help pruritis and discomfort or thrombosis.
If refractory to conservative management or debilitating pain or strangulation:
Rubber band ligation is MC; sclerotherapy or infrared coagulation
Excision of thrombosed external hemorrhoids
Hemorrhoidectomy - for stage IV or refractory
72
diverticulosis
In most cases, the bleeding stops spontaneously
If serious bleeding, resuscitation may be needed
Endoscopic therapy can be utilized to help control bleeding (epinephrine injection, tamponade)
Asymptomatic diverticulosis can be followed - recommend high fiber diet, use bran or psyllium.
