Research studies have shown that there is improved blood flow to the rectal mucosa after biofeedback therapy. [1] The overall rate of complete resolution of both symptoms and ulceration varies at 50-75%. [8] Stool frequency and straining effort decrease after this treatment. [1] In about 56% of cases, biofeedback treatment stops rectal bleeding ...
Patients with portal hypertensive gastropathy may experience bleeding from the stomach, which may uncommonly manifest itself in vomiting blood or melena; however, portal hypertension may cause several other more common sources of upper gastrointestinal bleeding, such as esophageal varices and gastric varices. On endoscopic evaluation of the ...
Mallory–Weiss syndrome is a condition where high intra-abdominal pressures causes laceration and bleeding of the mucosa called Mallory-Weiss tears. [1] Additionally, Mallory–Weiss syndrome is one of the most common causes of acute upper gastrointestinal bleeding, counting of around 1-15% of all cases in adults and less than 5% in children.
Glomerulations appear as checkerboard/lattice patterns, splotches, or pinpoint-sized red marks on the bladder. [7] [8] Glomerulations are classified into five grades that take into consideration the type and location of injury: Grade 0 (normal mucosa), Grade I (petechiae in at least two quadrants), Grade II (large submucosal bleeding), Grade III (diffuse global submucosal bleeding), and Grade ...
CT scans are often used in the evaluation of abdominal pain and rectal bleeding, and may suggest the diagnosis of ischemic colitis, pick up complications, or suggest an alternate diagnosis. [26] [27] [28] Endoscopic evaluation, via colonoscopy or flexible sigmoidoscopy, is the procedure of choice if the diagnosis remains unclear.
Mucosal biopsy may aid in ruling out alternate causes of proctitis, but is not routinely necessary and may increase the risk of fistulae development. [6] Telangiectasias are characteristic and prone to bleeding. [3] Additional endoscopic findings may include pallor (pale appearance), edema, and friability of the mucosa.
The size of these blood vessels varies from 1–5 mm (more than 10 times the normal diameter of mucosal capillaries). Pulsation from the enlarged vessels leads to focal pressure that causes thinning of the mucosa at that location, leading to exposure of the vessel and subsequent hemorrhage. [1]
The pressure difference causes the mucosal lining of the sinuses to become swollen and submucosal bleeding follows with further difficulties ventilating the sinus, especially if the orifices are involved. Ultimately fluid or blood will fill the space.
