GI, Liver and General Surgery for the MCCQE Part I: Bleeds, Belly Pain and Cirrhosis

Weight and scope

Sixteen questions is roughly twenty-three minutes. The domain splits into two styles. Surgical and acute stems ask what to do first in a patient with abdominal pain or bleeding. Medical stems ask you to interpret liver tests, recognize a complication of cirrhosis, or choose a treatment for inflammatory bowel disease. Colorectal screening links the domain to the prevention dimension and is among the most Canada-specific items.

The MCC publishes no discipline weights. The 7% figure is our editorial estimate from the MCC Examination Objectives and clinical presentations, and the count is rounded because some items in each section are unscored. Questions from this domain are also spread across the four dimensions of care and the four physician activities.

What is tested

• Bleeding. Upper GI bleeding and variceal hemorrhage, the initial resuscitation, endoscopy timing and acid suppression.
• Upper GI disease. Peptic ulcer disease and Helicobacter pylori eradication, GERD, Barrett esophagus and esophageal cancer, dysphagia and weight loss work-up.
• Lower GI and bowel disease. Crohn disease and ulcerative colitis, irritable bowel syndrome, celiac disease, diverticular disease, diarrhea and constipation.
• Acute abdomen. Appendicitis, bowel obstruction, perforation, mesenteric ischemia, cholecystitis, cholangitis and pancreatitis.
• Liver disease. Cirrhosis, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, viral hepatitis, alcohol-related and autoimmune liver disease, and jaundice patterns.
• Surgical basics. Hernias and their complications, anorectal conditions, and nutrition including enteral and parenteral feeding and refeeding syndrome.
• Cancer. Colorectal cancer presentations, screening and referral.

Canadian points to anchor your answers

• Colorectal screening. The 2016 task force statement for average-risk adults aged 50 to 74 is FOBT or FIT every 2 years or flexible sigmoidoscopy every 10 years, with no screening at 75 or older and no colonoscopy as a screening test. Most provincial programs use FIT every 2 years from 50 or 60, so name the source in your reasoning.
• Hepatitis C. The task force published a hepatitis C guideline in 2017. Check its current direction before relying on a screening group.
• Alcohol. Canada's Guidance on Alcohol and Health (2023) sets 1 to 2 drinks a week as low risk, 3 to 6 as moderate and 7 or more as increasingly high risk. This applies to alcohol-related liver disease counselling.
• Reportable infections. Viral hepatitis and some GI infections are reportable. The list is provincial, so learn the principle.
• Choosing Wisely Canada. Its lists include imaging and investigation choices in abdominal pain and GI disease. Use them to judge low-value tests.
• Units. Liver enzymes in units per litre, bilirubin in umol/L, hemoglobin in g/L.

How the questions are framed

Surgical stems give a short history and a few signs, then ask for the most likely diagnosis or the next step. The first step is often resuscitation or a specific bedside decision rather than a scan. Medical stems give liver tests or an endoscopy result and ask for the interpretation or the treatment. Chronic stems often hide the answer in a detail such as alcohol intake, a medication, a family history or a travel exposure.

Communication items cover new cancer diagnoses, alcohol counselling and explaining a screening result. Professional-behaviour items include consent for a procedure in a patient with reduced capacity and discussing a surgical complication.

Three typical traps

1. Over-investigating a patient who needs surgery or resuscitation. In peritonitis, perforation, obstruction with signs of ischemia or a bleeding patient, the next best step is stabilization and surgical review.
2. Using a non-Canadian screening rule. A colonoscopy-first answer from another country can be wrong here. Read whether the stem refers to the task force or to a provincial program.
3. Misreading the liver test pattern. Hepatocellular, cholestatic and mixed patterns point to different causes. Identify the pattern before choosing the test.

How to revise it

1. Learn the acute abdomen by location and by the one finding that changes management.
2. Make a cirrhosis map with each complication, its test and its first treatment.
3. Write a colorectal screening card with the task force version and a note on provincial programs.
4. Practise liver test patterns with ten short cases.
5. Finish with mixed blocks that include emergency and oncology stems.

Pair this domain with the emergency and critical care and infection, hematology and oncology pages, and with the Canadian guidelines guide for screening.

Subtopic checklist

Our blueprint lists these 18 subtopics for this domain. Tick each one only when you can state the presentation, the first investigation and the first management step without notes.

• Upper gastrointestinal bleeding and variceal hemorrhage
• Peptic ulcer disease and Helicobacter pylori eradication
• GERD, Barrett esophagus and esophageal cancer
• Inflammatory bowel disease: Crohn disease and ulcerative colitis
• Irritable bowel syndrome, celiac disease and malabsorption
• Colorectal cancer, screening and referral
• Acute appendicitis, bowel obstruction and perforation
• Diverticular disease and mesenteric ischemia
• Gallstone disease, cholecystitis and cholangitis
• Acute and chronic pancreatitis
• Cirrhosis, ascites, hepatic encephalopathy and spontaneous bacterial peritonitis
• Viral hepatitis, alcohol-related and autoimmune liver disease
• Hernias and their complications
• Anorectal conditions: hemorrhoids, fissure and abscess
• Jaundice interpretation and liver enzyme patterns
• Dysphagia and unintentional weight loss work-up
• Diarrhea and constipation: acute and chronic causes
• Nutrition, enteral and parenteral feeding and refeeding syndrome

How the four dimensions of care show up

Every question in this domain is classified under one dimension of care, so revise GI and surgery in four ways, not one.

• Health promotion and illness prevention. Prevention: colorectal screening, hepatitis vaccination, alcohol counselling and H. pylori eradication to prevent ulcer recurrence.
• Acute care. Acute: upper GI bleeding, appendicitis, obstruction, cholangitis and pancreatitis.
• Chronic care. Chronic: inflammatory bowel disease maintenance, cirrhosis surveillance, celiac disease and irritable bowel syndrome.
• Psychosocial aspects. Psychosocial: alcohol use disorder, eating disorders, nutrition insecurity and the stigma of liver disease.

When you review a wrong answer, note which dimension the question belonged to as well as the topic. A pattern, such as repeated errors on the prevention items, tells you more than a topic score.
