Osmotic laxatives can be used in patients not responding satisfactorily to bulking agents. Start with low-dose polyethylene glycol (PEG) as it has been demonstrated to be efficacious and well-tolerated in older adults.

Stimulant laxatives — Stimulant laxatives affect electrolyte transport across the intestinal mucosa and enhance colonic transport and motility.

The left side! Virchow’s node (left supraclavicular) is associated often with gastric cancer. The RIGHT supraclavicular node is associated with Hodgkins lymphoma, as the right node drains the mediastinum and it is common for HL to originate in the mediastinum.

148
Q

dilated veins in the distal esophagus or proximal stomach caused by elevated pressure in the portal venous system, typically from cirrhosis

Presents with: hematemesis with coffee ground/ Melena

Initial presentation: tachycardia/hypotension ⇒ may bleed massively but cause no other symptoms

A

Esophageal varices

Varices offer a channel that diverts pressure from the portal circulation. Often found in lower 1/3 of the esophagus and can extend into gastric veins

Dx: EMERGENT EGD after stabilizing patient
diagnostic and therapeutic

Labs: Hgb, Hct and Platelet (usually low in liver patients)

149
Q

Treatment for esophageal varices? Liver related

A

Treatment consists of intravenous octreotide which is a somatostatin analog that decreases portal blood flow
MOA:
Octreotide inhibits the release of glucagon, which is a splanchnic vasodilator.

Antibiotic prophylaxis with IV ciprofloxacin x1 week to lower the risk of a bacterial infection,
and
in severely-ill individuals, IV ceftriaxone is given instead

An upper endoscopy is done within 12 hours of presentation and variceal ligation with elastic bands placed on the varices to stop them from bleeding

150
Q

What is endoscopic sclerotherapy?

A

a sclerosant solution like sodium morrhuate is injected in the varices endoscopically

151
Q

What to do with massive bleed and if endoscopic therapy fails to stop the bleeding in esophageal varices?

A

Balloon tamponade using Blakemore tube
This applies direct pressure which can stop an ongoing bleed. It can be used for about 48 hours

When endoscopic approaches fail, another procedure is a
transjugular intrahepatic portosystemic shunt or TIPS, which creates a path between the portal and systemic circulation in order to lower the portal pressure

152
Q

How to preventrebleeds?

A

Nonselective beta-blockers - propranolol, nadolol (treatment of choice in primary prophylaxis to prevent rebleeds)
Isosorbide: long-acting nitrate

153
Q

What are considered alarm symptoms or features with abdominal pain, IBS?

x5

A

Alarm features include

  • Weight loss
  • Iron deficiency anemia –

-Family history of certain organic GI illnesses (eg, inflammatory bowel disease, celiac sprue, colorectal cancer)

Although rectal bleeding and nocturnal symptoms have also been considered alarm features

They are not specific for organic disease.

154
Q

What is post-parandial urgency with irritable bowel disease?

A

Postprandial urgency is common, as is alternation between constipation and diarrhea.
Symptoms not consistent with IBS should alert the clinician to the possibility of an organic pathology.

Inconsistent symptoms include the following: Onset in middle or older age Acute symptoms (IBS is defined by chronicity) Progressive symptoms 
Nocturnal symptoms 
Anorexia or weight loss 
Fever 
Rectal bleeding 
Painless diarrhea 
Steatorrhea 
Gluten intolerance
155
Q
Which of the following infections has been associated with an increased prevalence of IBS?
Giardia lamblia
Escherichia coli
Shigella
Salmonella
A

Infection with G lamblia has been shown to lead to an increased prevalence of IBS as well as chronic fatigue syndrome. In a historic cohort study of patients with G lamblia infection as detected by stool cysts, the prevalence of IBS was 46.1% as long as 3 years after exposure, compared with 14% in controls.
