TECAD Cirurgia Digestiva common mistakes
TECAD Cirurgia Digestiva · Understand the traps and how to avoid them.
On acute abdomen vignettes, choosing laparotomy immediately for every patient with peritonitis instead of first deciding resuscitation and whether laparoscopy is appropriate.
Candidates memorize 'peritonitis = surgery' as a reflex and skip the step of assessing hemodynamic stability, prior surgery, and whether the presentation suggests a benign or self-limited cause.
What to do instead
Before answering, write two lines: (1) is the patient unstable or stable, and (2) does the clinical picture mandate immediate source control or allow imaging/observation? Match the operative approach to stability and to the suspected diagnosis.
Confusing the diagnostic criteria and initial management of acute pancreatitis with those of chronic pancreatitis or pancreatic cancer.
All three present with epigastric pain and elevated enzymes in some form, and candidates conflate the two-of-three Atlanta criteria with tumor markers or with chronic pain management.
What to do instead
Anchor on the two-of-three rule for acute pancreatitis (typical pain, lipase/amylase above three times normal, imaging), then separately recall that chronic pancreatitis is a structural/functional diagnosis and pancreatic cancer is a tissue diagnosis with CA 19-9 as a monitoring tool, not a screening test.
Misclassifying lower gastrointestinal bleeding as upper bleeding or vice versa, and ordering the wrong first test.
Candidates see 'melena' or 'hematochezia' and jump to colonoscopy or EGD without linking the color and stability to the likely bleeding site and rate.
What to do instead
Use a decision tree: hemodynamically unstable or brisk hematochezia suggests a major lower or upper source and warrants urgent resuscitation plus EGD first when an upper source is possible; stable suspected lower bleeding starts with colonoscopy after prep. State the reasoning in one sentence before selecting the test.
Applying the Tokyo severity grading or the timing of cholecystectomy in acute cholecystitis incorrectly, such as recommending immediate surgery for every grade.
Guideline grades and timing windows are memorized as isolated numbers, and candidates do not map the grade to the recommended setting (laparoscopic early versus delayed versus percutaneous drainage).
What to do instead
Build a small table linking grade to timing and to the role of percutaneous cholecystostomy in high-risk patients, and rehearse one vignette per grade so the mapping becomes automatic.
Confusing the indications and technique of hernia repair types, for example recommending mesh in a contaminated field or choosing tissue repair for a large recurrent inguinal hernia without justification.
Candidates learn 'Lichtenstein for all inguinal hernias' and 'mesh is contraindicated in infection' as slogans without the nuance of contaminated-field options and recurrence risk.
What to do instead
For each hernia question, name the defect, the contamination status, and the patient risk factors, then justify mesh versus tissue repair and open versus laparoscopic approach explicitly.
Mismanaging the workup of obstructive jaundice by ordering the wrong sequence of imaging and missing the need for biliary decompression before surgery.
Candidates jump to ERCP for any dilated duct or to CT alone, forgetting that ultrasound is the first test and that cholangitis with sepsis requires urgent decompression.
What to do instead
Memorize the sequence ultrasound then MRCP or CT, with ERCP reserved for therapeutic decompression or stone extraction, and state the indication for urgent drainage when fever and hypotension are present.
Confusing the operative indications and expected outcomes of bariatric procedures, such as recommending a purely restrictive procedure for a patient with severe reflux or metabolic disease without justification.
Procedure profiles are memorized by name rather than by mechanism, so candidates cannot match malabsorptive versus restrictive versus mixed effects to the patient's comorbidity profile.
What to do instead
For each bariatric question, list the patient's dominant problem (reflux, diabetes, BMI, prior surgery), then match it to the mechanism of the candidate procedure and state the expected weight loss and nutritional risk.
Failing to recognize the indications for damage-control surgery and the timing of reoperation in trauma or severe abdominal sepsis.
Candidates treat every laparotomy as definitive and do not recall the triad of hypothermia, acidosis, and coagulopathy that mandates temporary closure and staged return.
What to do instead
Memorize the damage-control triad and the planned re-look timeline, and practice stating when to pack, when to leave the abdomen open, and what physiologic endpoints trigger return to the operating room.
Misapplying colorectal cancer screening and staging recommendations, such as choosing the wrong surveillance interval after polypectomy or confusing neoadjuvant with adjuvant therapy in rectal cancer.
Screening intervals and staging-based treatment pathways are numerous and similar, and candidates mix up colon versus rectal algorithms and the role of preoperative chemoradiation.
What to do instead
Create a one-page map separating colon from rectal cancer, with screening intervals by polyp type and the neoadjuvant indication for locally advanced rectal cancer, and test yourself with interval-based vignettes.
Overlooking perioperative risk assessment and prophylaxis, such as omitting venous thromboembolism prophylaxis or failing to adjust for cirrhosis and malnutrition before elective digestive surgery.
Candidates focus on the technical diagnosis and treat preoperative optimization as background noise, so risk-modifying steps are dropped from the answer.
What to do instead
End every operative-planning answer with a checklist: VTE prophylaxis, antibiotic prophylaxis, nutrition and cirrhosis assessment, and anesthesia risk, and verify each item is addressed before finalizing.
