- Steakhouse syndrome is an impacted esophageal food bolus.
- Occurs because they have an esophageal stricture (schatzki ring, scarring, esophagitis).
- Classic treatments have consisted of effervescents, glucagon, and/or sublingual nitroglycerin (NTG).
- Recent case series has shown oral 400mcg tablet of NTG dissolved in 10cc tap water was 100% successful.
- Complications of NTG are hypotension and headache.

- The sodium-glucose cotransporter in the gut is essential for rehydration.
- Oral rehydration therapies require an equimolar concentration of glucose and sodium to be effective.
- ORT has saved millions of lives globally.
- Consider using ORT in patients with dehydration. Especially useful in resource limited settings.

- The use of fecal occult blood tests is falling out of favor in emergency departments
- These tests have strong evidence suggesting their efficacy in colon cancer screening but clinical significance in ED is limited
- They have relatively high false positive and false negative rates
- Small/microscopic bleeding are often not clinically significant in the ED but can lead to increased costs from over-testing and other harms from fecal occult blood testing

- Rare disease with 1-2 patients out of 100,000. About 60% of patients report a preceding diarrheal illness and classically presents with an ascending motor weakness.
- Pathophysiology is likely due to molecular mimicry where the immune system creates antibodies against a pathogen (C. jejuni ) which appears similar to the myelin of peripheral nerves resulting in autoimmune demyelination.
- Diagnosis is made by clinical presentation +/- a spinal tap with a characteristic high protein count but without cells.
- Treatment is IVIG or plasmapharesis. It is important to monitor respiratory function because about 15% of patients progress to respiratory failure.

- Common pathologies include cholecystitis, choledocholithiasis, and in concerningly ascending cholangitis.
- Cholecystitis is obstruction at the cystic duct leading to inflammation of gallbladder wall, while choledocholithiasis is a distal obstruction of the biliary tree, and ascending cholangitis is an ascending infection of the biliary tree secondary to obstruction.
- Risk factors for Cholecystitis are the 5 F’s (Fat, Forty, Female, Fertile, Family Hx).
- Classic symptoms seen in ascending cholangitis are Charcot’s Triad of fever, RUQ pain, and jaundice, or Reynold’s pentad which is more severe and has the addition of
altered mental status and hypotension.
- Porcelain gallbladder is a radiographic finding showing calcification of the gallbladder that is associated with cancer of the gallbladder.

- Cannabinoid Hyperemesis syndrome is a relatively new diagnosis that presents with vomiting and abdominal pain without a clear etiology in the setting of daily marijuana use.
- The pathophysiology is not well-understood well, but may involve cannabinoid receptors in the gut.
- Treatment is abstinence from marijuana, fluids, dextrose, and antiemetics (haldol, ondansetron, etc). Opioids should be avoided.
- Capsaicin cream on the abdomen may be helpful, as it can distract from the pain and vomiting. Milk can be used to reverse its effects.

- Chronic diarrhea is defined as 3 or more loose, watery stools lasting more than 2-3 weeks.
- Look for clues in the history, including travel (could suggest infectious etiology), antibiotic use (could suggest C. Diff), and family history.
- Irritable Bowel Disease (Crohn’s/Ulcerative Colitis) is an autoimmune disorder that affects 1.3 million Americans and is a leading cause of chronic diarrhea.
- Crohn’s always involves the terminal ileum, but can present anywhere along the GI tract. It causes transmural inflammation of the bowel wall and can lead to adhesions, perforations, and fistulas. Ulcerative colitis usually involves the rectum and causes mucosal inflammation only.
- Workup for IBD includes colonoscopy and tissue biopsy.
- Treatment for IBD includes dietary changes, 5-ASA/Mesalamine, steroids, and infliximab (anti-TNF alpha).

- While C. difficile infections are generally thought of as nosocomial, there is a subset of patients who acquire the infection in the community.
- One recent study showed that about 10% of patients presenting to the ED with diarrhea and without vomiting had a C. diff infection.
- Another study found risk factors for community-acquired C. diff included recent ED/Urgent care visits and antibiotic use. However, 36% of the patients in that study had no identifiable risk factors.

- MI and GERD can present similarly. For example, 47% with angina report increased belching with an anginal attack, and 20% of people with an MI describe symptoms of indigestion that are relieved by antacids.
- Overall, GERD is more common in those with CAD, so don’t be “reassured” by GERD symptoms in the setting of chest pain.

- Boerhaave syndrome (aka effort rupture of the esophagus) accounts for 10% of esophageal ruptures and is usually caused by strain during vomiting episodes. It can also be caused by childbirth, seizure, or prolonged coughing or laughing.
- Food and water swallowed after the tear end up in the mediastinum, eventually causing infection. Therefore, Boerhaave syndrome is a surgical emergency.
- Best diagnostic techniques are CT or endoscopy.
- Mallory-Weiss syndrome may present similarly, however it is less serious since it involves only a small tear through the mucosa at the gastroesophageal junction. This can be managed on an outpatient basis with PPI’s.
