Build complete colorectal breadth

Colorectal Surgery Oral Board Practice Cases by Domain

A domain map that turns broad content coverage into speaking practice, operative defense, complication rescue, and literature-aware decision-making.

Key takeaways

  • Use the repository’s ten Colorectal Surgery domains as a coverage framework, not as a claim about an official ABCRS blueprint.
  • Every domain should include elective selection, emergency presentation, operation, postoperative care, and complication rescue.
  • Practice mixed rooms so performance transfers across rapid topic changes.
  • Original cases should test principles and evolving information rather than imitate recalled secure examination questions.

Educational domain map

ABCRS publicly describes a broad examination of colon and rectal diseases and surgery but does not publish a detailed public Part II topic allocation. SurgiTest organizes practice using its established Colorectal Surgery content domains.

Congenital and hereditary

FAP in a young adult

Choose timing and extent of prophylactic surgery, rectal preservation versus proctocolectomy, pouch candidacy, desmoid and duodenal surveillance, fertility, and family testing.

Lynch syndrome with colon cancer

Defend segmental versus extended colectomy, age and comorbidity, metachronous risk, gynecologic risk, molecular testing, and surveillance.

Pouch complication

Evaluate pelvic sepsis, fistula, Crohn phenotype, mechanical obstruction, pouchitis, cuffitis, dysplasia, function, and salvage versus excision.

Neoplasms

Obstructing right-colon cancer

Resuscitation, staging that does not delay care, resection, anastomotic judgment, hereditary assessment, pathology, and adjuvant planning.

Locally advanced rectal cancer

MRI anatomy, systemic staging, neoadjuvant sequencing, response, organ preservation, TME, margin, diversion, function, and surveillance.

Anal squamous-cell cancer

Biopsy, staging, chemoradiation, response assessment, salvage APR, inguinal nodes, HIV or immunosuppression, and wound reconstruction.

Synchronous liver metastases

Resectability, systemic therapy, primary symptoms, sequence, multidisciplinary strategy, ablation, portal-vein or hypertrophy strategies, and goals of care.

Inflammatory and infectious disease

Crohn stricture with abscess

Drainage, antibiotics, nutrition, medical therapy, timing, limited resection versus stricturoplasty, anastomotic risk, and recurrence prevention.

Acute severe ulcerative colitis

Resuscitation, infection testing, rescue medical therapy, daily surgical assessment, toxic megacolon, timely subtotal colectomy, and staged reconstruction.

Complex perianal Crohn disease

Drain sepsis, examination under anesthesia, seton, imaging, biologic coordination, continence, diversion, proctectomy, and wound risk.

Diverticular and appendiceal disease

Diverticular abscess

Antibiotics, drainage, failure criteria, fistula, interval evaluation, elective selection, and operative strategy.

Free perforation in shock

Resuscitation, antibiotics, operation, source control, primary anastomosis versus end stoma, damage control, and ICU plan.

Appendiceal mucinous neoplasm

Avoid rupture, pathologic category, extent of resection, peritoneal disease, staging, surveillance, and referral for cytoreductive strategy when appropriate.

Benign anorectal disorders

Recurrent fistula

Define anatomy and continence, MRI or ultrasound, seton, fistulotomy, sphincter-sparing options, Crohn disease, recurrence, and functional counseling.

Hemorrhoids with anticoagulation

Confirm the diagnosis, grade symptoms, optimize bowel habits, office treatment, operative selection, anticoagulation management, pain, bleeding, and stenosis risk.

Necrotizing perineal infection

Immediate resuscitation, antibiotics, broad debridement, serial operations, urinary or fecal diversion, critical care, reconstruction, and mortality discussion.

Functional and pelvic-floor disorders

Fecal incontinence

History, examination, stool optimization, manometry or imaging when useful, pelvic-floor therapy, sacral neuromodulation, repair selection, and quality-of-life goals.

Full-thickness rectal prolapse

Constipation and continence phenotype, frailty, defecography, abdominal versus perineal repair, resection decision, mesh considerations, recurrence, and function.

Slow-transit constipation

Exclude secondary and outlet disorders, document transit, pelvic-floor testing, maximize nonoperative therapy, select colectomy carefully, and counsel regarding pain and function.

Vascular, trauma, and iatrogenic injury

Ischemic colitis after low-flow shock

Severity, serial examination, imaging or endoscopy, antibiotics, operative threshold, resection, anastomosis versus stoma, and second look.

Colonoscopic perforation

Timing, bowel preparation, defect size and site, contamination, endoscopic closure, laparoscopic repair or resection, diversion, and delayed-presentation sepsis.

Rectal trauma

Anatomic level, associated injuries, contamination, repair or resection, diversion, presacral or distal washout controversies, antibiotics, and staged restoration.

High-yield perioperative practice

High-risk anastomosis

Nutrition, smoking, steroids, frailty, anemia, bowel preparation, antibiotics, perfusion, tension, diversion, and leak surveillance.

High-output ileostomy

Volume and renal assessment, medication and dietary review, output measurement, oral rehydration, antimotility strategy, obstruction, infection, and closure timing.

Postoperative urinary and sexual dysfunction

Baseline counseling, nerve injury or pelvic sepsis assessment, bladder management, specialist involvement, rehabilitation, and long-term follow-up.

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.
