Q

SPONTANEOUS BACTERIAL PERITONITIS (SBP)

“A 64-year-old man with a History of Hepatitis C presents with abdominal fullness, bloating, and chills. He says he has noted this his abdomen has become bigger and his pants do not fit as well as they used to. Exam shows shifting dullness and a fluid wave. VS show the patient is febrile (101.0F) and tachycardic. Labs show thrombocytopenia, low albumin, and INR of 2.3. “

What is the Best NEXT Step in the management of this patient?

A

Abdominal Paracentesis

This patient likely has cirrhosis and elevated portal hypertension based on his lab findings, low platelet count, low albumin, history of hepatitis C, and elevated INR – markers of impaired hepatic function.

17
Q

PERFORATION

ESOPHAGEAL PERFORATION

What are (3) Presenting Signs/Symptoms of Esophageal Perforation?

A
  1. Chest Pain or Upper Abdominal Pain
  2. Dysphagia or Odynophagia

18
Q

PERFORATION

ESOPHAGEAL PERFORATION

What is the Best INITIAL Test for Esophageal Perforation?

A

Gastrografin Contrast Esophagram

19
Q

OBSTRUCTION

What are (5) Symptoms that should cause you to suspect Obstruction?

A
  1. Severe Colicky pain
  2. Absence of Flatus or Feces
  3. High-pitched Bowel Sounds
  4. Nausea and Vomiting in patients with risk factors
  5. Constant Movement (patient tries to find comfortable position)
20
Q

OBSTRUCTION

What are the (6) Risk Factors in a patient with Nausea and Vomiting that should be concern for Obstruction?

A
  1. Prior abdominal surgery (adhesions)
  2. Elderly with weight loss and anemia or melanotic stools (tumor)
  3. Hx of Recurrent Lower abdominal pain (diverticulitis)
  4. Hx of Hernia (incarcerated)
  5. Sudden abdominal pain in Elderly (volvulus)
  6. Vascular events (ischemia, perforation/diverticulitis, AAA, or dissection)
21
Q

OBSTRUCTION

Which (3) Diagnostic Tests should be performed on a patient with suspected Obstruction?

A
  1. CBC and Lactate level (elevated)
  2. Supine and Erect Abdominal X-Ray:
    • Dilated loops of bowel
    • Air-fluid levels
    • Absence of Gas in rectum
    • Bird’s Beak sign for Volvulus
  3. CT Abd/Pel w/ contrast (Most ACCURATE Test)
    • Can show a Transition Point - location at which the obstruction has occurred.
22
Q

OBSTRUCTION

What are the (5) Treatments for Obstruction?

A
  1. NPO, NGT, and IVF
  2. Consider Gastrografin contrast study (until perforation has been ruled out).
  3. Sigmoid Volvulus: perform Proctosigmoidoscopy and leave the Rectal Tube in place. Perform Sigmoid Resection for recurrent cases.
  4. Hernia: perform Immediate Surgery if case describes Fever, Leukocytosis, Constant Pain, and Signs of Peritoneal Irritation (strangulated obstruction.
  5. All other Obstructions: perform Emergency Surgery
