How to Describe a Colorectal Operation During the Oral Boards
A precise method for turning procedural knowledge into an examiner-ready operation: enough detail to prove safety and judgment without drowning the answer in instrument-level narration.
Key takeaways
- Begin with indication, goal, approach, positioning, and the findings that would change the operation.
- Organize the description around exposure, anatomy, disease-specific planes, protection, resection, reconstruction, verification, and bailout.
- Name oncologic, functional, and physiologic principles—not merely a sequence of movements.
- Finish with specimen handling, stoma or anastomosis assessment, postoperative priorities, and the complication you will watch for first.
The seven-part operation skeleton
| Part | What to state | Why it matters |
|---|---|---|
| 1. Intent | Indication, operative goal, urgency, and alternatives | Shows selection before technique |
| 2. Setup | Consent, antibiotics, VTE prophylaxis, stoma marking, positioning, access, team and equipment | Demonstrates preparation for predictable risk |
| 3. Exploration | Peritoneal survey, disease extent, resectability, contamination, and unexpected findings | Establishes whether the planned operation remains appropriate |
| 4. Exposure and protection | Mobilization strategy, ureter, duodenum, autonomic nerves, gonadal structures, spleen, small bowel, and vascular anatomy | Proves anatomic control and injury prevention |
| 5. Disease-specific resection | Oncologic plane, vascular pedicle, margins, mesentery, bowel division, specimen orientation | Connects technique to disease biology |
| 6. Reconstruction and verification | Anastomosis or stoma, tension, perfusion, leak testing, hemostasis, drain rationale, bailout | Shows judgment at the highest-risk step |
| 7. Recovery | ERAS, pain, diet, fluids, urinary catheter, VTE prevention, pathology, function, surveillance | Demonstrates ownership beyond skin closure |
Right colectomy checkpoints
Selection
Confirm lesion location, staging, synchronous disease, hereditary context, obstruction or perforation, and whether extended resection is actually indicated.
Technique
Describe a medial-to-lateral or lateral-to-medial approach, ileocolic pedicle strategy, duodenal protection, mesocolic plane, hepatic-flexure mobilization, appropriate bowel and mesenteric margins, and specimen extraction.
Reconstruction
State anastomotic configuration, perfusion and tension assessment, mesenteric orientation, enterotomy closure, and leak or bleeding assessment.
Pivot
Explain what changes in shock, gross contamination, ischemic bowel, locally invasive disease, or unexpected peritoneal metastases.
Left or sigmoid colectomy checkpoints
Protection
Identify the ureter, gonadal structures, hypogastric nerves, spleen, and retroperitoneal plane before dense inflammatory or oncologic dissection.
Mobilization
Explain vascular control, mesenteric division, lateral mobilization, splenic-flexure decision, distal transection, and management of fistula or abscess.
Anastomosis
State perfusion, tension, orientation, stapler or hand-sewn plan, donuts when relevant, endoscopic or air-leak assessment, and diversion criteria.
Emergency branch
Choose primary anastomosis, diversion, end colostomy, subtotal colectomy, or damage control based on physiology, contamination, bowel quality, and operative findings.
Low anterior resection and TME checkpoints
Preoperative definition
State MRI relationship to mesorectal fascia, sphincter complex, levators, adjacent organs, tumor height, response to therapy, and functional baseline.
Pelvic dissection
Describe high-quality mesorectal-plane dissection, autonomic-nerve preservation, distal margin, circumferential margin, anterior and lateral planes, and control of a narrow or irradiated pelvis.
Reconstruction
State anastomotic level and technique, perfusion and tension, leak testing, diversion rationale, pelvic drain rationale, and contingency if a safe anastomosis is not achievable.
Function
Counsel regarding low anterior resection syndrome, urinary and sexual dysfunction, stoma expectations, and surveillance.
Abdominoperineal resection checkpoints
Indication
Explain why sphincter preservation would compromise margin, function, or safety and how the decision was discussed with the patient.
Two fields
Describe abdominal mobilization and pelvic dissection, perineal positioning and incision, levator strategy, specimen extraction, hemostasis, and avoidance of tumor perforation.
Perineal closure
State primary closure versus flap reconstruction based on defect, radiation, contamination, and wound risk.
Stoma ownership
Include preoperative marking, construction, perfusion, maturation, education, and early complication monitoring.
Proctocolectomy and pouch checkpoints
Selection
Confirm diagnosis, cancer or dysplasia, sphincter function, Crohn risk, comorbidity, fertility goals, obesity, nutrition, and willingness to accept pouch function and complications.
Staging
Choose one-, two-, or three-stage surgery based on steroids or biologics, malnutrition, anemia, urgency, sepsis, and physiologic reserve.
Pouch construction
Describe mesenteric reach, pouch configuration, anastomosis, perfusion, tension, leak testing, diversion, and specimen pathology.
Long-term plan
Discuss pouchitis, cuffitis, pelvic sepsis, obstruction, fistula, fertility, function, surveillance, and pouch failure.
A strong operative close
- The intended disease and specimen have been addressed.
- Hemostasis, perfusion, tension, orientation, and anastomotic integrity are confirmed.
- All protected structures are reassessed when appropriate.
- The stoma is viable, untwisted, tension free, and matured correctly.
- The postoperative pathway matches the patient’s physiology and operation.
- The first dangerous complication and its surveillance trigger are named.

Questions candidates ask
Frequently asked questions
What is the current ABCRS oral examination format?
ABCRS publicly states that each candidate undergoes at least three 30-minute oral examinations conducted in person by three two-member examining teams. The examination evaluates clinical experience, problem solving, surgical judgment, and familiarity with current literature in colon and rectal disease and surgery.
Does ABCRS publish a fixed number of cases in each room?
No fixed case count is stated in the public ABCRS format description. SurgiTest models each 30-minute room as an adaptive multi-case block and labels that case allocation as an educational simulation rather than an official Board rule.
Is the ABCRS oral examination based on personal cases?
The public oral-exam description does not identify a personal-case defense format. ABCRS does require an operative log during the application process, submitted through ACGME, but that credentialing requirement should not be represented as a published personal-case oral-exam structure.
Does ABCRS publish a candidate-facing numeric scoring rubric?
ABCRS publicly describes the abilities the examination evaluates, but it does not publish a simple candidate-facing numerical rubric or cut score that SurgiTest can reproduce. SurgiTest feedback is educational and is not an official ABCRS score or pass prediction.
Does SurgiTest reproduce recalled ABCRS questions or guarantee certification?
No. SurgiTest uses original educational cases and public format information. It does not reproduce secure examination content, claim ABCRS endorsement, calculate an official result, or guarantee certification.
